Black Widow

"I used to have nothing. And then I got this. This job. This family. And I was better because of it. And even though they're gone... I'm still trying to be better."

- Natasha Romanoff to Steve Rogers

Natalia Alianovna "Natasha" Romanoff, also known as Black Widow, was one of the most talented spies and assassins in the entire world and a founding member of the Avengers. Originally a KGB operative and dangerous assassin, Romanoff was recruited into S.H.I.E.L.D. by Clint Barton. Having extensive mastery in martial arts and armed with her Widow's Bite, Black Widow became one of S.H.I.E.L.D.'s most efficient agents. During one mission, she was sent undercover into Stark Industries to watch Tony Stark due to the fear that he was dying. During this mission, Romanoff assisted Stark with defeating Ivan Vanko's terrorist plots against him.

When Loki declared war on the Earth, Black Widow was recruited into the Avengers after Hawkeye had just been enthralled by Loki. Romanoff assisted in recruiting Stark and Bruce Banner into the team while they tracked down and attempted to capture Loki, eventually saving Barton from his grasp. Once Loki's entire plan had been uncovered, Romanoff joined the team during the Battle of New York and was instrumental in destroying the portal over the city which had been created by the Tesseract, effectively ending the entire invasion while Loki was defeated and captured.

In the wake of the Avengers successfully defeating Loki, Romanoff had continued her work with S.H.I.E.L.D., this time working with Captain America. While working together, Romanoff and Rogers uncovered a conspiracy following an assassination attempt on Nick Fury, which had eventually led to them discovering that HYDRA had somehow been infiltrating their entire organization. Despite the efforts of the Winter Soldier to stop them, Romanoff helped expose Alexander Pierce's evil schemes to the world, which also resulted in all of her own morally dubious history being revealed. As a result, Romanoff was forced into dropping off the grid again and began rebuilding her cover.

Romanoff eventually rejoined the Avengers, working to bring down various HYDRA cells across the world and assisting in the capture of Wolfgang von Strucker. However, before she could form a romantic relationship with Banner, the rogue artificial intelligence Ultron was created by Stark and Banner, forcing Romanoff and the rest of their team to join together and defeat him. Despite being captured, Romanoff was able to inform the team of Ultron's location on Sokovia, resulting in a final battle in which the Avengers had defeated Ultron once and for all. Unlike most members of the original Avengers, Black Widow remained a member while forming the second incarnation of the team.

As many of the governments of the world had demanded the Avengers to sign the Sokovia Accords in the wake of their recent battles, Romanoff agreed to their terms and signed the Accords. She later joined Iron Man in a fight against Captain America due to his disagreements with the Accords and his criminal activities with the Winter Soldier who Rogers was attempting to protect. As the two Avengers' factions fought against each other, Romanoff betrayed Iron Man's team in order to assist Captain America to find the instigator of the team's fight. As a result, Black Widow had to escape from the government for aiding Rogers, while being on the run, Romanoff soon joined him and Wilson in stopping terrorists.

When the threat of Thanos approached Earth, Romanoff, Rogers, and Wilson protected Vision, who had the Mind Stone, which Thanos was after. They later defended Wakanda from the attack and managed to kill all of Thanos' forces but unfortunately Thanos effortlessly overpowered Romanoff and the other heroes when he personally came to Wakanda and destroyed half of all life in the universe with the assembled Infinity Gauntlet, with Romanoff being one of the survivors.

After meeting Captain Marvel, Romanoff was part of the Ambush on Thanos in an effort to retrieve the Infinity Stones and undo the Titan's snap, with no success. Five years later, Romanoff led the Avengers alongside Captain America, now formed by Okoye, Rocket Raccoon, Nebula, War Machine, and Captain Marvel.

In order to undo the Snap, the remaining Avengers split up in teams to retrieve all Infinity Stones from an alternate timeline. Romanoff was sent to retrieve the Soul Stone on Vormir with Hawkeye. Having been told by Red Skull a sacrifice was required for the Stone, she and Hawkeye fought to be the one sacrificed, ultimately resulting in the both dangling off a cliff and Romanoff on the lower end, holding onto Hawkeye's hand. Romanoff begged Hawkeye to let her go, and after shaking herself loose, let go and fell to her death in exchange for the Soul Stone.

Red Room Training
"In the Red Room, where I was trained, where I was raised, they have a graduation ceremony. They sterilize you. It's efficient. One less thing to worry about. The one thing that might matter more than a mission. Makes everything easier, even killing."

- Natasha Romanoff to Bruce Banner

Natalia Alianovna Romanoff was born in 1984 in Stalingrad. At a young age, Romanoff was recruited by the KGB. At a Red Room Academy, she endured both an education and indoctrination into the world of spy-craft. Romanoff excelled in this strict training environment and soon became regarded as a master spy and one of the world's greatest assassins. Her ruthless effectiveness in later years earned her the code name, Black Widow, deriving from the Red Room program she went through. As a final ceremony to complete her training, Romanoff was sterilized, as to avoid any distractions and focus solely on her missions, something she deeply regretted later in her life.

On S.H.I.E.L.D.'s Radar
"I have a very specific skill set. I didn't care who I used it for, or on. I got on S.H.I.E.L.D.'s radar in a bad way. Agent Barton was sent to kill me. He made a different call."

- Black Widow to Loki

Due to both her expertise and her growing threat to global security, Romanoff quickly appeared on S.H.I.E.L.D.'s radar, prompting Nick Fury to send Clint Barton to eliminate her. Hawkeye disobeyed this order, recognizing her skill, and recommended her for recruitment for S.H.I.E.L.D. At the behest of Fury, Romanoff later defected from Russia and joined the ranks of S.H.I.E.L.D.

From that moment on, she developed a lasting partnership with Barton, becoming best friends with each other. Together, they had tactical missions within Budapest, and many other locations. The pair became so close that Romanoff was the only other person Barton told about his family. She became a close family friend to them and adopted an aunt-like relationship with their children.

The Winter Soldier
"Five years ago, I was escorting a nuclear engineer out of Iran, somebody shot at my tires near Odessa. We lost control, went straight over a cliff, I pulled us out, but the Winter Soldier was there. I was covering my engineer, so he shot him straight through me."

- Natasha Romanoff to Steve Rogers

In 2009, when she was assigned to protect a nuclear scientist, she was attacked by the Winter Soldier, who was sent to kill the scientist. Though she and the scientist were pushed over a cliff, Romanoff managed to save both herself and the man she was protecting. Seeing this, the Winter Soldier fired a single round through Romanoff's stomach and into the scientist, effectively killing him.

After this encounter, Romanoff would go on to attempt to track down the Winter Soldier for an unspecified amount of time, but was forced to give up after accepting that he was more elusive than any other enemy she had encountered.

Natalie Rushman
"Oh, wow, very, very impressive individual. She's fluent in French, Italian, Russian, Latin. Who speaks Latin?" "No one speaks Latin, it's a dead language. You can read Latin, or you can write Latin, but you can't speak Latin." "Did you model in Tokyo? 'Cause she modeled in Tokyo."

- Tony Stark and Pepper Potts

Under the name "Natalie Rushman", Romanoff did modeling work in Tokyo, Italy, France and United States as part of an undercover operation from 2005 to 2007. Romanoff was then sent on one of her usual missions, sent to ruin an operation of the Ten Rings. She boarded the Ten Rings plane and caused its explosion. Just as she was fighting off a Ten Rings operative in the plane, she was sent by Nick Fury to infiltrate Stark Industries.

Later, Romanoff was hired as a Stark Industries notary public by Bambi Arbogast. Romanoff worked her way at getting to Tony Stark in many ways, including secretly making Samantha Carlisle sick in order to deliver documents to Stark.

Watching Tony Stark
"Who is she?" "She is from legal, and she is potentially a very expensive sexual harassment lawsuit if you keep ogling her like that." "I need a new assistant."

- Tony Stark and Pepper Potts

The ulterior motive for her employment was for her to keep an eye on Tony Stark after he signed his company over to Pepper Potts. In reality, Romanoff had been assigned to assess whether he was suitable for a Avengers Initiative. Romanoff arrived as Potts' replacement catching the attention of Stark and Happy Hogan while they were boxing. Romanoff obtained signatures from Potts as Stark asked for her name and then telling her to join him in the boxing ring. Stark then told Hogan to give Romanoff a lesson for which Hogan didn't take seriously not being aware of her training. Stark ran a search on her and discovered that she was fluent in French, Italian, Russian, and Latin and had done some modeling in Japan. As Romanoff watched Stark ogle her, Hogan went to hit her, but Romanoff blocked the blow and scissored him around the head and pinned him to the ground. Romanoff then got out of the ring and obtained Stark's fingerprint and then left, leaving Stark astounded. Romanoff went on to be Stark's assistant from then on.

Monaco
"You look fantastic." "Why thank you very much." "But that's unprofessional. What's on the docket?" "You have a nine-thirty dinner." "Perfect, I'll be there at eleven."

- Tony Stark and Natasha Romanoff

Romanoff met Stark and Potts in Monaco who greeted them and guided Stark with the photographers and informed him of his nine-thirty dinner which he told her he'll arrive at eleven. When Stark appeared on the television, contesting in the Monaco Grand Prix, Potts called Romanoff over to see if she knew about it which she didn't. Potts asked for Romanoff to get Hogan and bring him to her so they could stop Stark.

Stark's Party
"If this was your last birthday party you were going to have, how would you celebrate it?" "I would do whatever I want to do, with whoever I wanted to do it with."

- Tony Stark and Natasha Romanoff

On Tony Stark's birthday, Romanoff walked in on Stark, who was observing his Arc Reactor in his chest which was getting worse, with a selection of watches to wear for his party. The two then talked about whether he should cancel his party due to recent events. Romanoff then covered up some of Stark's bruises on his face as Stark asked her what she would do if it was her last birthday, which she told him that she would do whatever she wanted with whoever she wanted to do it with before leaving. Taking in what Romanoff said, Stark got really drunk, flirting with Romanoff and letting her wear the Mark IV's gauntlet and blast an ice sculpture. After being frustrated with Stark's behavior, James Rhodes stole Iron Man Armor: Mark II and engaged in a fight with Stark, causing the party guests to leave. During Stark's and Rhodes' fight, Romanoff ran into Potts who confronted her saying that ever since she arrived she knew something wasn't right. Suddenly, the fight made its way to the two causing them to evacuate. Romanoff then contacted Nick Fury and debriefed him on the situation. When he offered to come, she told him not to.

Revealing Herself to Stark
"We've secured the perimeter. But I don't think we should hold it for too much longer." "Huh. You're f... fired." "That's not up to you."

- Black Widow and Tony Stark

Now dressed in her S.H.I.E.L.D. uniform, Romanoff met with Fury at Randy's Donuts to provide a short-term antidote to Stark's palladium poisoning. Sneaking in from the back entrance, Romanoff surprised Stark as she revealed to be a S.H.I.E.L.D. agent the entire time. Stark said she was fired, but Romanoff made it clear that it wasn't up to him. Fury introduced her to Stark revealing Natalie Rushman isn't her name and that she was assigned by Fury to watch him. Romanoff gave Stark a serum which postponed the effects of the Arc Reactor's radiation, which was poisoning his body, so he could work on a cure. Later, Romanoff, along with Fury and Phil Coulson, went to Tony Stark's Mansion and she was told by Fury that she was to remain in position as an assistant. Later at Stark Industries Headquarters, while Stark was visiting Pepper Potts, Romanoff walked in and requested for Potts to sign something. Romanoff was told by Potts to sort out the personal belongings with Stark. When Potts left, Stark started to grill Romanoff and told her that he found it amazing that she does what she does. When he claimed that she could not speak other languages, she replied in Latin, then repeated herself in English, telling him that he could, "Either drive himself home or she can have him collected."

Hunt for Ivan Vanko
"When we arrive I need you to watch the perimeter. I'm gonna enter the facility and take down the target. Watch the road."

- Natasha Romanoff to Happy Hogan

At the Stark Expo, Romanoff was in attendance with Pepper Potts when Ivan Vanko started to take control over the Hammer Drones. Romanoff and Potts followed Justin Hammer where they discovered that Vanko had taken control over the drones after Romanoff threatened Hammer. Romanoff left Potts and went outside where she ordered Happy Hogan to go to Hammer Industries Headquarters. As they drove, Romanoff got changed in the back into her S.H.I.E.L.D. uniform, causing Hogan to try to watch. When they arrived at the facility, Romanoff told Hogan, who was confused about what she was wearing, to stay in the car. Romanoff broke into the facility and the two were approached by a guard who Hogan engaged in a fight while Romanoff continued. She then defeated any guards in her way using multiple gadgets like her Taser Disks, Flash Bombs, Wire and as well as her skills. Romanoff managed to defeat all the guards with ease and continued to Vanko's location where she found he wasn't there. Romanoff was able to gain back control over Rhodes' battle suit. She also informed Iron Man of Vanko arriving at his location after they defeated all the Hammer Drones. She then retrieved Hammer Industries data before Ivan Vanko's bombs went off.

Big Problems
"These are gods and monsters and machines of war we're mixed up with."

- Natasha Romanoff

Returning to S.H.I.E.L.D. Headquarters with the data, she was given orders by Nick Fury to go to Culver University and watch over Bruce Banner. She arrived and witnessed Banner get locked in the bridge by Thaddeus Ross and the United States Army; Banner then transformed and a battle ensued.

She called Fury and barely escaped uninjured. She revealed to Fury that she witnessed Emil Blonsky in action against Hulk and that they enhanced him. Fury was forced to deploy Romanoff to Grayburn College after Ross revealed, in a short conversation, that he intended to capture Banner. She arrived too late, however, and informed Fury over the phone that Ross captured Banner and was taking him away in a helicopter. Romanoff was then ordered to make sure that Banner did not leave anything for Samuel Sterns, with whom he had recently been, to work on. As she headed up the front steps, she witnessed Blonsky, now as Abomination, emerge from the building. She was buried in rubble, but still managed to make her way upstairs. She stumbled upon Sterns, whose mutation had heightened significantly, and his brain power had been augmented exponentially. After a brief dialogue with him, during which Sterns identified Black Widow's birthplace from a hint of accent in her voice, Romanoff shot him in the leg.

She called in a S.H.I.E.L.D. cleanup team and signaled her location on the roof with flares. She saw the chaos of Abomination and Hulk's battle in the distance. Back at S.H.I.E.L.D. Headquarters, she confronted Fury, stating that all of the events going on were too much to handle.

Security on the Helicarrier
Ignorant that Nick Fury had ordered Hawkeye to check the security of the Avengers Initiative database, Romanoff attacked Barton when he infiltrated the Helicarrier while wearing a mask. Fury arrived and stopped the scuffle; the three then discussed Fury's choices for the Avengers.

Back in Russia
"And... what do you get out of this if you "win"?" "Oh, I'm sorry, didn't I mention? If I win, I take over the mantle of "Black Widow"."

- Natasha Romanoff and Sofia

Once again on a mission, Romanoff arrived in Moscow where she searched for missing Stark Industries technology. Disguised as Tatiana Sokolova, she worked at a nightclub. While trying to interrogate Mikhail Fjodorov, one of the world's most successful illegal arms dealers, Fjodorov was killed by an unknown woman and Romanoff was forced to leave the club via the roof, fighting several security men.

After she returned to a hotel, she was attacked by a team of masked mercenaries, but she defeated them and received a SIM card to reach the mysterious woman she has seen in the night club. Later, Romanoff talked to Sofia and learned that she is a "fan" and wants to take over the name "Black Widow". Romanoff agreed to meet with Sofia and broke all her contacts with S.H.I.E.L.D..

A few days later, Romanoff confronted Sofia in a sports hall in Sochi, where she almost drowned in cold water, but she was saved at the last moment by Phil Coulson, who was following a pair of goons working for Starodoub. Coulson gave Romanoff the necessary equipment to infiltrate the yacht belonging to Yuri Klementiev, one of Starodoub's business partners, where she met Sofia again, an encounter which cost them Gennady Markov's life.

When Coulson discovered that Sofia was employeed by Richard Frampton, Natasha infiltrated his headquarters in Vladivostok. She discovered that Frampton works for the Ten Rings and that he had made a Jericho missile that would explode near the border between Russia and North Korea, greatly destabilizing the world peace. Romanoff infiltrated the launching area and destroyed the missile. Both Frampton and Sofia were killed in the explosion.

Interrogated by Georgi Luchkov
"I'll brief you on everything when you get back. But first, we need you to talk to the big guy." "Coulson, you know that Stark trusts me about as far as he can throw me." "Oh, I've got Stark. You get the big guy." "Боже мой!"

- Phil Coulson and Black Widow

Romanoff was tasked by S.H.I.E.L.D. with find and take down Georgi Luchkov who illegally sold weapons to the highest bidder. Romanoff was sent to spy on Luckkov's activities in Russia, however, she was knocked out from behind by his henchmen, who caught her sneaking around. When she awoke, she found herself tied to a chair, yet when Luchkov interrogated her, he unknowingly spilled all of his secrets. However, as Luchkov was preparing to seemingly torture Romanoff, and whilst the mention of torture gave Romanoff a scare, her interrogation was interrupted when Phil Coulson called and requested to speak to Romanoff. Coulson informed Romanoff that she needed to come in which she refused as she was in the middle of an interrogation, but when Coulson informed her that Clint Barton was compromised as an incentive. Romanoff put Coulson on hold and then immediately freed herself and fought and captured Luchkov and his men. Coulson told Romanoff to go recruit Bruce Banner which she hesitated and asked to recruit Tony Stark, which Coulson had covered. Romanoff then picked up her shoes and left the warehouse and went to go recruit Bruce Banner.

Recruiting Bruce Banner
"You know, for a man who's supposed to be avoiding stress, you picked a hell of a place to settle." "Avoiding stress isn't the secret." "Then what is it? Yoga?" "You brought me to the edge of the city, smart. I... assume the whole place is surrounded?" "Just you and me."

- Natasha Romanoff and Bruce Banner

Romanoff traveled to Bruce Banner's hidden location in Kolkata, India. She had a child to act as if her father was sick to lead him into an abandoned house. Banner realized that it was a set up as Romanoff calmly introduced herself and explained the situation to him. Romanoff told Banner that it was just the two of them, which was a lie as multiple S.H.I.E.L.D. agents were outside. She told Banner about the Tesseract and that they require his help to locate it as the Tesseract emits a weak Gamma Radiation signal. Banner reassured that Hulk was not needed which Romanoff told him that Nick Fury had not mentioned anything about Hulk. When Romanoff tried to assure Banner that he would not be imprisoned, Banner mocked rage to test her reaction; she pulled a gun on him and aimed it at his head, but Banner calmly explained he was testing her. Romanoff then ordered agents outside to stand down and convinced Banner to come with her.

Assembling On The Helicarrier
"It was quite the buzz around here, finding you in the ice. I thought Coulson was gonna swoon."

- Natasha Romanoff to Steve Rogers

Romanoff brought Bruce Banner onto the Helicarrier, to help locate the Tesseract. Phil Coulson then arrived with Steve Rogers and introduced the two before Romanoff told Coulson that he was needed on the bridge. The two then walked together and got acquainted and asked him if Coulson asked him to sign his trading cards. She introduced Banner to Rogers and recommended that they move inside as it would become hard to breathe. The Helicarrier then began to take off so the three went inside. Inside the Helicarrier, Romanoff showed Banner to his lab and continued to search for Clint Barton.

Capturing Loki
"I'd sit this one out, Cap." "I don't see how I can." "These guys come from legends, they're basically gods." "There's only one God, ma'am. And I'm pretty sure he doesn't dress like that."

- Black Widow and Captain America

S.H.I.E.L.D. located Loki in Stuttgart, Germany and Romanoff flew on Quinjet to this location with Steve Rogers. As Captain America fought Loki, Romanoff tried to get a shot at Loki but was unable to due to Loki using his magic to make multiple illusions of himself appear. Suddenly loud AC/DC'S "Shoot to Thrill" started to play on the Quinjet as Iron Man flew in to help to ask if she had missed him, making Romanoff smile. They succeed in capturing Loki and brought him on the Quinjet to take him to the Helicarrier.On their way back in the Helicarrier, Nick Fury asked Romanoff whether Loki had said anything, which Romanoff informed him that Loki had stayed silent. Suddenly an unexpected lightning storm was taking place and Thor suddenly entered the Quinjet and left with Loki in tow. Romanoff asked if Thor was another Asgardian as Iron Man went to retrieve him. Rogers then went to join Stark, when Romanoff warned him that he should sit this one out as Thor comes from legend and is basically a god, but he chose to fight anyway.

Interrogating Loki
"Regimes fall every day. I tend not to weep over that, I'm Russian. Or I was." "And what are you now?" "It's really not that complicated. I've got red in my ledger, I'd like to wipe it out." "Can you? Can you wipe out that much red? Dreykov's daughter? São Paulo? The hospital fire? Barton told me everything."

- Black Widow and Loki

As Loki was being locked up, Romanoff listened in as he and Nick Fury talked to each other. Romanoff told Thor that Erik Selvig and Clint Barton are under Loki's control. When Thor told Bruce Banner to take care of how he speaks about Loki as he is his brother, Romanoff informed him that Loki had killed eighty people in two days making Thor tell them that Loki was adopted. Romanoff decided to interrogate Loki and find out his intentions. Romanoff approached the demigod Loki, undetected so she could interrogate Loki which he noted that not a lot of people could sneak up on him. Romanoff wanted to know what Loki has done with Clint Barton which Loki told her that he had expanded his mind. Whenever Romanoff asked what would happen to Barton after Loki had conquered Earth, Loki questioned Romanoff's feelings asking if it was love. Romanoff made it clear that she owed Barton a debt and she told Loki about her history with Barton. Loki instead told Romanoff that she fought in the service of killers her whole life, asking her if she would be willing to sacrifice the fate of humanity for the safety of Barton. Romanoff decided to pretend to break down her barriers to Loki so he would reveal his plans. Loki then began to taunt Romanoff telling her about her history which Barton had told him about. Loki then told Romanoff that he would force Barton to kill Romanoff but he ended up revealing that he planned on unleashing Hulk. Romanoff then warned S.H.I.E.L.D. about Loki's plan and went to escort Banner to his room.

Loki's Manipulation
"Loki is manipulating you." "And you've been doing what exactly?" "You didn't come here because I bat my eyelashes at you." "And I'm not leaving because suddenly you get a little twitchy."

- Black Widow and Bruce Banner

After figuring out Loki's plan to unleash Hulk, Romanoff made her way to the lab Bruce Banner was working in to escort him. An argument then broke out between the Avengers due to the effects of the Mind Stone. Romanoff stayed silent for most of the time except when she tried to escort Banner to his cell. While the group argued, Clint Barton, under the control of Loki, fired an explosive arrow onto the Helicarrier which blew up the lab. Romanoff was briefly knocked out and she and Banner were thrown into another room.

Attack on the Helicarrier
"Doctor Banner... Bruce, you gotta fight it. This is just what Loki wants. We're gonna be okay. Listen to me. We're gonna be okay, right? I swear on my life, I will get you out of this! You will walk away, and never–" "Your life?!"

- Black Widow and Bruce Banner

Whilst Romanoff lay senseless on the floor, a large piece of equipment had fallen on to her foot, and she awoke to find herself trapped with Bruce Banner transforming into Hulk. Romanoff attempted to calm Banner down, but he was too angry. Romanoff saw two S.H.I.E.L.D. agents coming to help, but she told them to leave, knowing they would be in danger. As Romanoff tried to free herself, she witnessed as Banner transformed into Hulk, leaving Romanoff horrified. Romanoff eventually freed herself and attempted to escape from Hulk. Filled with rage, Hulk chased after Romanoff and nearly killed her. Romanoff tried to hide from Hulk but she could not escape from him. Romanoff attempted to fend herself off from Hulk and barely did causing her to try to run away from Hulk. Hulk managed to outrun Romanoff and threw her aside, which winded her and broke 2 of her ribs. As Hulk went to kill Romanoff, Thor charged into Hulk saving Romanoff. Still dazed after her encounter with Hulk, Romanoff was forced to take on Clint Barton who was under Loki's control. Barton was walking down the Helicarrier when he was confronted by Romanoff who snuck up behind him in an attempt to disarm him. The two friends had a prolonged fight using her combat skills, Romanoff was able to fight Barton and defend herself from his attacks with his bow and arrows and knife. When the fight got dirtier, Romanoff used her teeth to disarm Barton. Barton used all his top-level training to kill his friend, including firing several arrows at her, although Romanoff was able to dodge them, as well as attempting to drive a knife into her neck while pulling her hair back. In the end, Barton was no match for Romanoff's speed and quick-thinking and eventually, she got the upper hand, disarming him and slammed Barton's head onto a steel pipe. The blow weakened Loki's grip on Barton's mind and he recognized Romanoff, calling her by her first name before she knocked him out with a final strong punch to the head, breaking his connection to Loki and restoring his mind. Romanoff watched as Barton was taken away by a S.H.I.E.L.D. team to be rehabilitated.

Clint Barton's Recovery
"Do you know what it's like to be unmade?" "You know I do."

- Clint Barton and Natasha Romanoff

After Romanoff defeated Clint Barton, he was arrested and tied down until it was certain that Loki's control was gone and he was no longer a threat. Romanoff looked after Barton in the recovery room, listening to him as he described the experience, which he compared to being unmade, which Romanoff understood from past experiences. Despite him asking, Romanoff refused to tell Barton how many S.H.I.E.L.D. agents he had killed, telling him that Loki and Loki alone was responsible for the killings and he must not blame himself. When Captain America arrived to ask Romanoff if she could pilot a Quinjet, Barton told him he could. After Romanoff gave him the nod of approval, Rogers allowed Barton to join them on the mission.

Battle of New York
"Just like Budapest, all over again." "You and I remember Budapest very differently."

- Black Widow and Hawkeye

Black Widow was prepared to fight Loki beside the other Avengers and his Chitauri army, though being a spy and not a soldier. Hawkeye flew her and Captain America to New York City in a Quinjet where the portal had already opened over the city, allowing thousands of aliens to enter and attack. Loki managed to shoot the Quinjet out of the sky and the team fought the extraterrestrials on the ground. Bruce Banner, meanwhile, reunited with the Avengers, arriving to the site on a motorcycle. Banner deemed it an appropriate time to morph into the Hulk. Alongside Hawkeye, Black Widow fought the oncoming horde of Chitauri soldiers until the rest of the Avengers arrived. Black Widow used all her skills and weapons to defeat the Chitauri army while the civilians all clear out. While Black Widow and Hawkeye fight the Chitauri, she reminded him that the situation of being similar to a mission they took place in Budapest, which Hawkeye told Black Widow that he remembered Budapest differently. When the others arrived, Captain America ordered that Black Widow and he would stay on the street to protect the people and keep the fight where they could control it. She and Captain America fought hard; She used her Black Widow's Bite and guns to kill dozens of Chitauri soldiers. However, the fight was almost too exhausting for her.

Closing the Portal
"Captain, none of this is going to mean a damn thing if we can't close that portal." "Our biggest guns couldn't touch it." "Well, maybe it's not about guns."

- Black Widow and Captain America

After a while the plan of keeping the fight contained proved meaningless; she decided to obtain one of the Chitauri Chariots and fly it to Stark Tower. On the way she was chased by Loki and called on Hawkeye to shoot him out of the sky. She eventually made it to Stark Tower where the portal to their domain was open and met Erik Selvig, who had come out of the mind control. Together, using Loki's scepter, they closed the portal for good, ending the invasion. As Loki was taken into custody, Romanoff and Barton elected to remain in Stark Tower to rest from the battle. Later, the team took a breather at the Shawarma Palace before they were interrupted by War Machine, who arrived too late to help in the battle. The Avengers gathered together in Central Park the next day to send Thor with Loki and the Tesseract back to Asgard. While Loki was in chains, Romanoff whispered something in Barton's ear about Loki's punishment, causing Barton to grin. When the team went their separate ways, Romanoff left with Barton in a S.H.I.E.L.D. car.

Zodiac
"A lie, yes... but well-intentioned."

- Natasha Romanoff

After participating in the Battle of New York, Romanoff became partners with Captain America and they ran many operations together. One such operation occurred upon the theft of the Zodiac weapon from S.H.I.E.L.D. Romanoff was tasked to infiltrate Baker's terrorist cell using the alias "Audrey". Posing as Audrey, she spent several weeks undercover determining what Baker's plan for Zodiac was.

Upon discovering Baker's plan to release the Zodiac in the Willis Tower in Chicago during the height of the day, killing all within, Romanoff alerted Captain America. Romanoff, Rogers, and Brock Rumlow confronted Baker's cell in the Skydeck of Willis Tower, and after a brief combat, subdued the terrorists, and recovered the Zodiac.

Brooklyn
"My work for S.H.I.E.L.D. has taken me all over the world... and that is, without a doubt, not just the best milkshake in Brooklyn... but on the whole darn planet."

- Natasha Romanoff to Steve Rogers

Receiving intel that Sana Amanat was going to be abducted, Nick Fury dispatched Romanoff and Steve Rogers to New York City on protection detail. Under the guise of Rogers showing Romanoff the places that he grew up, they managed to draw out the Cadre mercenaries that had set up in multiple locations throughout the neighborhood. Tracing the mercenary that had abducted Amanat through a maze of alleyways, Rogers succeeded in taking out the last mercenary with a little help from Amanat herself.

Picking up Rogers
"Hey, fellas. Either one of you know where the Smithsonian is? I'm here to pick up a fossil."

- Natasha Romanoff to Steve Rogers and Sam Wilson

Romanoff drove down to Washington, D.C. where she would pick up Steve Rogers who was talking with Sam Wilson. Romanoff sent Rogers a text to meet her as they had a mission and drove up to the two. As Rogers made his way in the car, Romanoff joked about his age by calling him a fossil. The two then drove away to meet up with the STRIKE team.

Fighting the Pirates
"You're saving S.H.I.E.L.D. intel." "Whatever I can get my hands on." "Our mission is to rescue hostages." "No, that's your mission, and you've done it beautifully."

- Captain America and Black Widow

Romanoff and Rogers were sent with the STRIKE unit to retake the Lemurian Star that was hijacked by pirates led by Georges Batroc. Romanoff and Rogers were debried about their mission by Brock Rumlow. As the team got ready to land, Romanoff and Rogers chatted about Saturday night plans which Rogers had none. She also tried to get Rogers to ask a woman out but he claimed he was too busy as he jumped out of the Quinjet without a parachute. As the Rogers and the rest of STRIKE team went to rescue the hostages, Romanoff suggested that he ask out the nurse across the hall from him and proceeded to the engine room. As Batroc ordered a pirate to start the engines, Romanoff snuck up behind him and knocked him out, as well as several other pirates as she grappled down the boat. Rogers asked Romanoff for her status as she was in the middle of a fight with a few pirates in the engine room. She secured the room and knocked out the final pirates with a blow to the face with a steel pipe. She then proceeded with her mission, collecting the confidential information regarding Project Insight on the flash drive. When Rogers knocked out Batroc, he discovered Romanoff's real mission was to retrieve confidential protected S.H.I.E.L.D. files in a flash drive. Romanoff insisted that his mission was to rescue the hostages, while hers was to secure the information on the Lemurian Star. As the two argued about the mission, Batroc threw a grenade at them which Rogers knocked away and Romanoff shot the glass and the two jumped through the window, just getting clear of the blast. Romanoff took responsibility for Batroc getting away and the two made their way to the Quinjet.

Fury's "Death"
"Most of the intelligence community doesn't believe he exists. The ones that do call him the Winter Soldier. He's credited with over two dozen assassinations in the last fifty years."

- Natasha Romanoff to Steve Rogers

Romanoff met up with Steve Rogers at the hospital and witnessed Nick Fury being operated on. Romanoff asked Rogers about the shooter as Maria Hill joined them telling the two the ballistics were untraceable. The three then watched as the doctors attempted to revive Fury but were failing to leave Romanoff devastated as she watched Fury "die". Romanoff said her goodbyes to Fury when Hill told them that she needed to take Fury. Romanoff then asked Rogers why Fury was in his apartment the night he was shot which he told her he did not know but Romanoff could tell that he was lying. After Rogers was made a fugitive, he went back to the hospital to retrieve the USB he left in a vending machine behind pieces of gum only to find it was gone. Romanoff then stood behind Rogers chewing gum implying she took the USB. Rogers questioned Romanoff about the USB's location and what was on it which she told him that it was safe and that she didn't know what was on it. She then told him that Fury was killed by an assassin known as the Winter Soldier and she had encountered him once before.

On the Run from S.H.I.E.L.D.
"Kiss me." "What?" "Public displays of affection makes people very uncomfortable." "Yes, they do."

- Natasha Romanoff and Steve Rogers

Romanoff, who was now also on the run from S.H.I.E.L.D., followed Steve Rogers and they went to an internet cafe to see if there was any valuable information on the drive. As Romanoff tried to decrypt the USB, she informed Rogers that they had nine minutes until S.H.I.E.L.D. would find them. As the two looked through where the USB files came from, Aaron asked if they needed help which Romanoff told him that she and Rogers were looking for honeymoon locations as the USB located where the files originated, New Jersey. Brock Rumlow and STRIKE unit attempted to find them but failed to do so. On the way out Romanoff made Rogers kiss her to make oncoming STRIKE agents avert their gaze.

HYDRA's Plan
"Project Insight requires insight. So I wrote an algorithm." "What kind of algorithm? What does it do?" "The answer to your question is fascinating. Unfortunately, you shall be too dead to hear it."

- Arnim Zola and Natasha Romanoff

They stole a car and drove to Camp Lehigh in New Jersey. The two talked during the drive including Romanoff asking if the time they kissed in the mall was the first kiss he had since 1945. They then arrived at the army camp where Rogers had trained during World War II. At first, Romanoff thought the base was a dead end due to there being no heat signatures of radio signals, making her believe whoever wrote the files must have used a router to throw people off. Rogers then discovered a building which was in the wrong place of the base and they then entered. There, they found a secret storage room full of old computers inside an abandoned S.H.I.E.L.D. office. In there they found a more modern looking USB slot and they put the USB in. Having inserted the USB drive, Romanoff quoted a line from an old movie, asking Rogers if he watched it to which he replied yes.The computers powered up and someone began to talk to them. The voice turned out to be Arnim Zola, who told them that he was recruited by S.H.I.E.L.D. after World War II and that he helped to rebuild HYDRA, inside S.H.I.E.L.D. In the 1970s, after being told he would soon die, he transferred his mind into a computer. As Rogers noted that HYDRA died with the Red Skull's demise, Zola countered his statement, revealing that he used his recruitment as an opportunity to rebuild HYDRA, implying that HYDRA masterminded behind dozens of events that changed history. Romanoff and Rogers soon learned Zola was also involved in the Winter Soldier Program with Zola providing some blurred photos of the Winter Soldier eliminating HYDRA threats such as Howard Stark and Nick Fury. But before Rogers and Romanoff could get any more information out of Zola, Alexander Pierce sent a missile to Camp Lehigh, blow up the base. They both survive the blast, however, Romanoff was knocked unconscious.

Seeking Refuge
"When I first joined S.H.I.E.L.D. I thought I was going straight. But I guess I just traded in the KGB for HYDRA. I thought I knew whose lies I was telling, but I guess I can't tell the difference anymore." "There's a chance you might be in the wrong business."

- Natasha Romanoff and Steve Rogers

The next day, Romanoff and Rogers went to seek refuge with Sam Wilson as everyone else they knew was trying to kill them. Romanoff told Rogers that when she joined S.H.I.E.L.D. she believed she was going straight instead of just trading the KGB for HYDRA. Romanoff then asked Rogers would he trust her if it was up to her to save his life which he told her he trusts her now. Wilson then interrupted the two to inform them that he made breakfast which he was unsure if that was something they ate. Romanoff and Rogers began to question who could launch a domestic missile strike which Rogers figured out it was Alexander Pierce, as Zola's algorithm was onboard the Lemurian Star along with Jasper Sitwell. As the two thought how to kidnap a S.H.I.E.L.D. officer as they are the most wanted people in Washington which Wilson suggested that he do it and showed them files of missions that he had been on as well as files on the EXO-7 Falcon suit he used on his missions. Wilson told them where they could find one of the EXO-7 Falcon suits and the protection it has, which Romanoff saw as no trouble.

Kidnapping Jasper Sitwell
"Is this little display meant to insinuate that you're gonna throw me off the roof? Because it's really not your style, Rogers." "You're right. It's not. It's hers."

- Jasper Sitwell and Steve Rogers

Focusing their attention to Jasper Sitwell, Natasha, Sam, and Steve located the HYDRA mole and abducted him. Despite having been interrogated at the top of the roof as a means of intimidating him, Sitwell refused to answer the questions, only taunting Rogers that he could not throw him off the building, only for Romanoff to kick him off the building. The two then discussed people who Steve could date, including Sharon Carter, his neighbor. Terrified, Sitwell finally confessed that HYDRA had hijacked Project Insight, further explaining that Zola's Algorithm was developed to eliminate potential threats to HYDRA, including Bruce Banner and Stephen Strange, and many others. Still under duress, Sitwell proceeded to reveal that HYDRA's ultimate plan was to use the Insight Helicarriers to eliminate the list of threats directly from the Triskelion.

Return of the Winter Soldier
"Insights launching in sixteen hours. We're cutting it a little bit close here."

- Natasha Romanoff

As Romanoff, Steve Rogers and Sam Wilson drove their way to infiltrate the Triskelion, they were interrupted when they were attacked by the Winter Soldier who jumped on their car and threw Jasper Sitwell out, killing him. Romanoff went to shoot the Winter Soldier when an oncoming car ran into them from behind, causing Romanoff to drop her gun. When the Winter Soldier caused the car to crash, Rogers grabbed Romanoff and Wilson and jumped out of the moving car. While Rogers crashed into a bus, Romanoff and Wilson came under heavy fire. As the Winter Soldier and HYDRA mercenaries shot at the two, Romanoff continued to shoot back at them while hiding behind a car, until the Winter Soldier shot the car shielding her with one of his grenade launchers, forcing her onto the intersecting highway. Romanoff used her Black Widow's Bite to grapple off the bridge, while a car fell off the bridge, exploding. As the firefight continued, Romanoff attempted to outrun the Winter Soldier, only for her to see his shadow from above the highway. Romanoff then decided to trick the assassin into believing that he killed her. Believing that he successfully killed Romanoff, the Winter Soldier attempted to shoot at a bus's engine to cause an explosion, until Romanoff suddenly shot the Winter Soldier in his goggles from the ground. She then used that opportunity to move behind the bus for protection. However, the Winter Soldier survived due to his protective goggles, and responded by shooting at Romanoff's direction with his gun. As the two mercenaries shot at each other, Romanoff decided to run in hope to escape but the Winter Soldier personally decided to pursue her while the mercenaries were dispatched to find and kill Rogers. Knowing she could not escape the Winter Soldier, Romanoff distracted him with a radio message on her phone letting her get the jump on him. As the car exploded, however, the Winter Soldier immediately discerned the trick and turned around. As the Winter Soldier spotted her, he engaged in a hand to hand fight with Romanoff. She was able to use her skills as a former spy to use deception and gadgets to gain the upper hand against her opponent. She managed to temporarily subdue the Winter Soldier and attempted to strangle him. However, he threw her off and attempted to shoot her until she disabled the Winter Soldier's Prosthetic Arm with her Taser Disk. After temporarily subduing the Winter Soldier, Romanoff continued to run and telling civilians to leave and stay out of harm's way until was shot in the shoulder. As the Winter Soldier finally attempted to eliminate Romanoff, Rogers interrupted their fight, saving her. Rogers then fought the Winter Soldier himself until his mask was removed revealing himself to be Bucky Barnes. Before he could shoot Rogers, Romanoff saved him by firing a grenade launcher, causing him to flee. A team STRIKE agents led by Brock Rumlow and Jack Rollins apprehended Romanoff, Rogers, and Wilson.

Reuniting with Fury
"We have to stop the launch." "I don't think the Council's accepting my calls anymore."

- Natasha Romanoff and Nick Fury

During the drive, Steve Rogers informed Sam Wilson and Romanoff that the Winter Soldier's true identity was Bucky Barnes, his friend who supposedly perished during World War II. As Rogers told Romanoff that Arnim Zola was most likely the mastermind behind Bucky's transformation into the assassin that he currently was, Wilson could see the Romanoff needed a doctor as she was losing blood from her gunshot wound. The three were rescued by Maria Hill who disguised herself as a STRIKE agent and knocked out another guard. Hill took them to a secret facility where an alive Nick Fury shocked Romanoff. Romanoff was then taken to Fine who treated her wound as Fury told them how he faked his death. After Romanoff was bandaged up, Hill and Fury revealed that there was a plan in place to stop Project Insight. The group decided that at the end of all of it, that S.H.I.E.L.D. and HYDRA had to be eliminated for good.

Battle at the Triskelion
"I'm sorry. Did I step on your moment?"

- Black Widow to Alexander Pierce

To stop Project Insight, Romanoff used a Photostatic Veil to disguise herself as Hawley and infiltrated the World Security Council. As Romanoff stayed with Alexander Pierce, Captain America, along with Falcon and Maria Hill infiltrated the Triskelion and revealed that S.H.I.E.L.D. was compromised by HYDRA. The council was held hostage by STRIKE who were all HYDRA agents until she took them down and stopped Pierce from executing Singh, thus revealing herself to everyone. Romanoff then began disabling security protocols, releasing all of S.H.I.E.L.D. and HYDRA's secrets onto the Internet. When the encryption required to be disabled, which needed two Alpha Level members, Romanoff told Pierce that company was coming right as Nick Fury arrived. Fury and Pierce gave their authorizations to release all of the files which Romanoff pointed out that it was trending on the internet. Pierce then activated a button on his phone causing all of the council members chests to explode due to their security tags except for Romanoff's. As Captain America and Falcon were successful in destroying the Helicarrier's, Romanoff was ordered by Pierce to accompany him, but as he escaped but Romanoff used her Black Widow's Bite to disarm her security tag, knocking herself out and letting Fury shoot Pierce, killing him. Fury then checked on the unconscious Romanoff, who came round shortly after. Romanoff and Fury then piloted the helicopter and flew to Falcon's location, where a Helicarrier was crashing into the side of it. They flew the chopper around the northwest corner to catch Falcon who dove out of the window and fell through the chopper, but was caught by Romanoff and pulled him up. The three then flew away as Romanoff asked Hill if she knew where Captain America was.

A New Start
"You need us. Yes, the world is a vulnerable place, and yes, we help make it that way, but we're also the ones best qualified to defend it. So if you want to arrest me, arrest me. You'll know where to find me."

- Natasha Romanoff

Romanoff later attended a government inquiry into the HYDRA affair. When asked why no one has heard from Steve Rogers, which she believed there was nothing more for him to say due to the wreck in the middle of the Potomac made his point. Romanoff also told them that HYDRA was selling the government lies instead of intelligence which General S. Scudder pointed out that Romanoff was responsible for handing out those lies. When it was brought to attention that Romanoff should be arrested, she stated that she and the other agents that fought against HYDRA in the HYDRA Uprising would not be arrested because they are the best qualified to protect the world and then left the inquiry. Now that her secrets were revealed to the world, Romanoff needed a new identity.

One Last Favor
"That thing you asked for, I called in a few favors from Kiev. Will you do me a favor? Call that nurse." "She's not a nurse." "And you're not a S.H.I.E.L.D. agent."

- Natasha Romanoff and Steve Rogers

At the personal request of Rogers, Romanoff had contacted some of her acquaintances in Kiev who sent her an old top secret document about the Winter Soldier and his own long history working for HYDRA. Later, she stopped by Nick Fury's fake grave, she told Rogers that she wasn't going with Fury or staying as she had blown all her covers and needed new ones. Romanoff gave the document to Rogers and told him to do her a favor and call Sharon Carter and kissed him goodbye. Before she left she told Rogers to be careful before digging deeper into finding the Winter Soldier.

Finding Her Parents
"After everything that happened with S.H.I.E.L.D., during my little hiatus, I went back to Russia and tried to find my parents. Two little graves linked by a chain fence. I pulled some weeds and left some flowers. We have what we have when we have it."

- Natasha Romanoff to Steve Rogers

A few months later, after Phil Coulson's reorganization of S.H.I.E.L.D., Romanoff contacted Melinda May. A while after S.H.I.E.L.D.'s downfall, Romanoff went back to Russia in hope to find her parents who she barely knows. When she got a location, all she found were two graves so she placed some flowers on them. Romanoff then returned home accepting to accept what she had when she had it.

Fighting HYDRA
"Thank you for choosing Air Widow. We hope you've enjoyed your flight."

- Black Widow

With the rising threat of HYDRA, the Avengers team was officially reassembled, with the financial backing of Tony Stark. Using the Avengers Tower as their headquarters, they embarked on several missions to thwart HYDRA's plans for world domination. Romanoff was in Sudan when she hijacked a plane carrying HYDRA operatives meeting with Jensen who had perfected a weapon using Chitauri technology. Finding a platoon of armed soldiers there, Romanoff had J.A.R.V.I.S. assemble the Avengers to provide her with assistance. Ultimately, the Avengers and Romanoff defeated HYDRA and Jensen and destroyed her weapon.

Attack on the HYDRA Research Base
"Loki's Scepter must be here. Strucker couldn't mount this defense without it. At long last." "At long last is lasting a little long, boys."

- Thor and Black Widow

Avengers' next mission together was to recapture the Scepter from HYDRA Research Base. Romanoff stole a jeep so she and Hawkeye could keep up with the rest of the Avengers as they fought HYDRA soldiers. Romanoff crashed the jeep and pursued to fight on foot using her skills and weapons to kill many HYDRA operatives sent by Wolfgang von Strucker. When Thor pointed out that the Scepter must be at the base at long last, Romanoff said that the long last was lasting a little longer. When Hawkeye was injured, Romanoff immediately went to aid and told the others that they needed to evacuate. When the battle was won, Romanoff watched as the remaining HYDRA soldiers were being apprehended by the Iron Legion. Captain America told Romanoff to get to Hulk and calm him down. As Romanoff approached Hulk, she took off her gloves and began the lullaby method to calm him down. The lullaby worked and it caused Hulk to calm down and transform back into Bruce Banner. On the way back to Avengers Tower, Romanoff told Banner that the lullaby worked better than ever although he was not expecting the battle to need Hulk. Romanoff then told Banner that if he had not of fought than Barton would have been killed. Romanoff asked Thor for an assessment of Banner's skills on the battlefield; Thor commented on Hulk's violence has resulted in the deaths of dozens of HYDRA soldiers. Seeing that this upset Banner, Thor told him that many of the injuries he inflicted on the soldiers were nonfatal.

Celebration
"How'd a nice girl like you wind up working in a dump like this?" "Fella done me wrong." "You got lousy taste in men, kid." "He's not so bad. Well, he has a temper. Deep down, he's all fluff. Fact is, he's not like anybody I've ever known. All my friends are fighters, and here comes this guy, spends his life avoiding the fight because he knows he'll win."

- Bruce Banner and Natasha Romanoff

When the Avengers returned from Sokovia, Romanoff stayed by Clint Barton's side while his injured skin was being repaired by Helen Cho using a device called the Cradle. Romanoff asked if her friend was going to be ok and she joked that pretending to need him brought the team together. Bruce Banner explained what the Cradle is and Cho mentioned that Barton's girlfriend wouldn't even be able to notice the difference which Barton told her that he did not have a girlfriend, not mentioning his wife which only he and Romanoff knew about. Tony Stark organized a party in Avengers Tower to celebrate their victory against and obtaining the Scepter. During the Party, Romanoff talked with James Rhodes and bartended for the guests. Romanoff flirted with Bruce Banner, so he would understand that she had feelings for him. Romanoff told Banner about how all her friends are fighters except him as he stays out of the fight as he knows he would win. Before long many of the guests had departed leaving on the Avengers and a few others. As they sat around and drank, Thor invited the Avengers to try and lift Mjølnir. Romanoff watched as the Avengers failed at lifting the hammer and when Banner's turn came, he pretended to turn into Hulk, which none of the others found funny, except Romanoff. Banner invited Romanoff to attempt to lift Mjølnir but as she drank her beer, she politely declined to claim that it was a question that she didn't need answering.

Attack on Avengers Tower
"I'm ready. I'm on a mission." "What mission?" "Peace in our time."

- Ultron and Natasha Romanoff

The party was interrupted when one of Tony Stark's Iron Legion made a surprise appearance, and after admitting that it was the result of Stark's Ultron Program mixed with his research into the scepter, it and several more like it, attacked the group. Romanoff took cover behind the bar and dragged Bruce Banner after her causing him to fall on her, which she reminded him to transform into the Hulk. She then drew a pistol concealed under the bar to help with the fight. She then covered Banner as the two made their way to a safer sort upstairs. However, the attack was a diversion, and one of the robots made off with the scepter while the Avengers and their friends were engaged in battle. Eventually, all the armors were defeated except for the first Iron Legion who announced his intentions to end the Avengers to achieve his idea of peace.

Argument
"He's been in everything. Files, surveillance. Probably knows more about us than we know about each other."

- Natasha Romanoff

After the brief fight, the team discussed what had occurred. Romanoff said that Ultron had deleted all their files and that he was in the surveillance. She also said that he maybe knew about them more they knew about each other. Tony Stark admitted his involvement in the creation of Ultron, although he still strongly defended the idea as he believed it was a beneficial plan to save the world. Thor, clearly furious at Stark's recklessness, charged in and grabbed Stark by the throat, but Steve Rogers was able to calm him down. The team later learned that Ultron had sent them a message by murdering Wolfgang von Strucker and leaving the word "peace" written in his blood. Together they worked out that Ultron would be going after Vibranium and he would get that from Ulysses Klaue in Johannesburg.

Battle at the Salvage Yard
"Natasha, I could really use a lullaby." "Well, that's not gonna happen. Not for a while."

- Iron Man and Hawkeye

When reports of robots attacking sources of Vibranium began surfacing, the Avengers raced to a coastal scrapyard in Africa, where they found Ultron, along with Quicksilver and Scarlet Witch, taking the Vibranium. As Iron Man, Captain America and Thor confronted Ultron directly, Black Widow and Hawkeye stayed further back to provide cover. As peaceful negotiations quickly failed, Ultron and the Maximoffs attacked, at the same time Ulysses Klaue sent his mercenaries to attack the Avengers. Romanoff took down many of Klaue's men to protect the rest of the Avengers from attack as they took down the Ultron Sentries, holding her ground until she was eventually overwhelmed and knocked out. Klaue's men then turned their attention to Hawkeye, who managed to take them down and clear the area. Romanoff came to shortly after, yet was incapacitated when Wanda Maximoff snuck up behind Widow whilst she was still dazed and inflicted a nightmarish vision upon her. Widow languished in a scene from her past while the fight carried on around her and the enemy made their escape.

Seeing Visions
"You'll break them." "Only the breakable ones. You're made of marble. We'll celebrate after the graduation ceremony." "What if I fail?" "You never fail."

- Natasha Romanoff and Madame B.

In the vision that Scarlet Witch had inflicted upon Romanoff, she woke up and relived experiences in the Red Room Academy the place she had grown up in and was trained to be an assassin. Romanoff walked down the stairs where she came across Madame B., her former trainer, who commented on Romanoff not being breakable and told her that they will celebrate after the graduation ceremony. Romanoff displayed worry of failing, but Madame B. assured her she wouldn't. Romanoff then shot at a few targets followed by a human who she the executed. Romanoff proceeded to relive her experiences during her graduation doing some training where she was holding back so she wouldn't have to go through the ceremony. Madame B. made it clear that the ceremony was necessary in order for Romanoff to take her place in the world, which she believed she didn't have. Romanoff was then sterilized, as to avoid any distractions and focus solely on her missions. As half of the Avengers were suffering from Wanda Maximoff's nightmares, Iron Man was chasing after Hulk, who had also fallen victim to Wanda's powers and was on a rampage. Iron Man requested Romanoff to give Hulk his lullaby method to calm him down, but Hawkeye informed him that she was not going to be able to help him as she was disoriented by the visions. As the Avengers retreated in the Quinjet, Romanoff, along with Steve Rogers, Thor and Bruce Banner remained temporarily scarred by what they saw in the visions.

Retreat
"It's bad right? Nat seems really shaken." "Ultron has these allies, these kids, punks really."

- Laura Barton and Clint Barton

Still suffering from the effects along with the rest of the Avengers, Romanoff was forced to make a quick escape to the Quinjet not being able to give the Hulk his lullaby. Iron Man was then forced to stop the Hulk's current destructive rampage through Johannesburg, as Banner was also affected by Wanda Maximoff's powers. The Avengers become unpopular due to a massive battle between Hulk and Iron Man in his "Hulkbuster" armor in the middle of South Africa; at the same time many of the members were still suffering from the effects of Maximoff's visions. Maria Hill stated that there was no information about Banner's arrest order yet. Knowing they needed to get away and recover, Clint Barton flew the team to his homestead, realizing that no one would be able to find them there.

Barton's Homestead
"How's little Natasha?" "She's... Nathaniel." "Traitor."

- Natasha Romanoff and Laura Barton

The Avengers arrived at Barton's homestead where Barton helped her make her way to the house as she was still haunted by the ghosts of her past. Romanoff's troubles were washed away when she was welcomed by Laura Barton and their two children who consider her family by calling her "Aunty Nat". Romanoff talked with Laura about her pregnancy only to be disappointed when she found out that they baby is a boy and not going to be a "Natasha", but a "Nathaniel".

A Life with Banner
"I had this dream. The kind that seems normal at the time, but when you wake..." "What did you dream?" "That I was an Avenger. That I was anything more than the assassin they made me."

- Natasha Romanoff and Bruce Banner

As Romanoff waited for Bruce Banner to get out of the shower, she thought about her visions a dream that she had about being an Avenger. When Banner got out, the two talked about their relationship as well as the visions they were shown. Romanoff told Banner about the dream she had where she believed she was an Avenger and not an assassin that the Red Room created.

Romanoff suggested that they run away together but it was rejected by Banner as he believed he could not live a normal life like what Barton had both as a threat and not able to have kids. Romanoff told him that she was also not able to have kids due to the Red Room's graduation ceremony where she was sterilized to stop her from distractions. Believing herself to be a monster like what Banner considers himself, the two then considered to run away.

Fury's Inspiration
"So stand. Outwit the platinum bastard." "Steve doesn't like that kind of talk." "You know what, Romanoff..."

- Nick Fury, Natasha Romanoff and Steve Rogers

Nick Fury also arrived at the farm and spoke with the group at length about stopping Ultron. While they listened, Romanoff was brought a drawing of a butterfly by Lila Barton. Fury went on to inspire the Avengers who had been defeated by Ultron and called Ultron a platinum bastard causing Romanoff to continue a running joke between the Avengers about Steve Rogers telling Tony Stark to watch his language. While trying to think where Ultron would be, Banner figured out he wanted to evolve by using the cradle. Romanoff, Barton, and Rogers got ready to leave for Seoul where they believed Ultron would be as he needed to use the cradle.

Battle of Seoul
"I'm always picking after you, boys."

- Black Widow

After Banner made the observation that Ultron was trying to evolve, the remaining Avengers split into two groups, with Black Widow joining Captain America and Hawkeye in a bid to stop Ultron obtaining the Cradle in South Korea. The trio raced for their objective and found that Ultron's plan to create a new android body for itself was already well underway, but the Avengers' arrival caused it to grab the body and flee. Hawkeye located Ultron escaping in a truck trailer in heavy traffic, and when a window of opportunity presented itself, Romanoff dropped to the streets on a motorcycle to pursue it herself. Romanoff made her way through the city, being guided by Hawkeye to reach Ultron's location. As she made her way, she noticed Captain America's Shield on the road and picked it up. She eventually made her way to their location where Ultron was beating Captain America who she rescued by threw him his shield. Romanoff then boarded the truck which became airborne, but she was successful in delivering the dormant android to Hawkeye. However, whilst entering the Quinjet, she was knocked out and taken captive by Ultron.

Ultron's Plans Revealed
"I wasn't sure you'd wake up. I hoped you would. I wanted to show you... I don't... have anyone else."

- Ultron to Black Widow

When she awoke, Romanoff found that she had been transported back to HYDRA Research Base in Sokovia, where Ultron made a show of demonstrating his latest upgrade to her. He revealed to her his plan, still believing that the Avengers are the problem, before confining her to a cell. Romanoff, watching in horror, watches as Ultron destroys his body after building a new and stronger one. After he left, she turned to use an old Cold War-era communication technique in a bid to expose her location without being detected, but could do little else but sit and wait.

Rescue
"You're not going to turn green?" "I've got a compelling reason not to lose my cool." "I adore you. But I need the other guy."

- Black Widow and Bruce Banner

Hawkeye eventually received her signal and revealed it to the rest of the Avengers leading them to fly to Sokovia to defeat Ultron and rescue her. As she sat in her cell, Thor destroyed a wall and he and Bruce Banner entered to find Romanoff. Banner eventually made his way to the cell and freed her by blasting the cell open with Chitauri Gun.

While Banner wanted to run away with Romanoff, she knew that she had to stay and fight, so after kissing Banner, she pushed him down a hole causing him to transform into the Hulk. Romanoff then held onto Hulk as he jumped from HYDRA Research Base to the airborne Sokovia. The two made their way to Novi Grad and continued to help the rest of the Avengers fight the fight to stop Ultron.

Battle of Sokovia
"Well, it's not like we ever had a place in the world..."

- Black Widow

Black Widow regrouped with Captain America and asked if Scarlet Witch was wearing her jacket. Captain America informed her that she was with them which didn't explain the jacket to her. Rogers told them that fighting the robots was getting the nowhere, Hawkeye joined the group and told them that the air is getting thin. Scarlet Witch and Hawkeye left and Black Widow asked Rogers what do they do. He told her they fight robots as she took out her Batons. The Avengers fought hard to break the ranks of Ultron Sentries in Novi Grad. Black Widow used her martial arts mastery and weapons, along with her new taser batons, to fight the robots alongside her fellow teammates.

Reinforcements
"I'm not leaving this rock with one civilian on it." "I didn't say we should leave. There's worse ways to go. Where else am I gonna get a view like this?" "Glad you like the view, Romanoff. It's about to get better."

- Captain America, Black Widow and Nick Fury

When Iron Man told Captain America that his only solution to save the world from Novi Grad being smashed into it was to destroy Novi Grad itself, Rogers refused to entertain the idea. Black Widow, however, tried to persuade Steve to consider the option as the world's population would logically take precedence over the people of Novi Grad. When Rogers declared he wouldn't leave Novi Grad and its people to their fate, Black Widow told him that she never intended for them to leave and that they would die with the people of Novi Grad if needed. She reassured herself and Rogers that there are worse ways to die and that at least she'd die seeing a great view. Nick Fury interrupted their conversation by saying that Romanoff's view was about to get a lot better. Fury revealed his Helicarrier and used it to enact Rogers' plan and evacuate the civilians while War Machine joined the battle. Fury sent out a squad of rescue boats to evacuate the citizens while Black Widow and the Avengers ensured no one was left behind.

Protecting the Key
"Romanoff? You and Banner better not be playing hide the zucchini." "Relax, shellhead. Not all of us can fly."

- Iron Man and Black Widow

Iron Man then came up with a plan to dispose of Novi Grad and called all the Avengers to the city church where the drill was located. Iron Man jokingly told Black Widow that she and Hulk better not be playing "hide the zucchini". Black Widow retorted that she was en route slower since she could not fly as she used a bulldozer to run over Ultron Sentries. The Avengers were tasked with protecting the drill in the church known as the key so that Ultron could not activate it. Ultron unleashed his army of Ultron Sentries upon them in a final offensive. Black Widow and the Avengers put all their force into destroying the seemingly endless horde of Ultron Sentries, with Black Widow using her guns and Bite to destroy many of the robots. After a vicious battle, the Ultron Sentries were eventually pushed back. When Ultron attempted to join the fight in his strongest form, the Vision, Iron Man and Thor nearly destroyed him with their combined powers. With the battle almost won, Captain America ordered the team to get to a rescue boat and leave the city before Iron Man and Thor destroyed the city. Black Widow went with Hawkeye and confiscated a car, making small talk about how to renovate his homestead during their drive.

Losing Banner
"Hey, big guy. We did it, the job's finished. Now I need you to turn this bird around, okay? We can't track you in stealth mode, so help me out. I need you to–"

- Black Widow to Hulk

As the battle wound down, Black Widow and Hawkeye turned their attention to evacuating the civilian populace, but soon she received the call to calm Hulk back to his human state. However, the process was interrupted by Ultron, who raked Hulk with gunfire whilst at the controls of the Avengers' own Quinjet, and knocked Romanoff out. Hulk grabbed Romanoff and bore her to safety on a newly arrived Helicarrier, before leaping after Ultron to vent his rage. Romanoff soon learned that Hulk had beaten Ultron in the departing Quinjet and appealed to him through a video link to disengage the plane's stealth technology, but Hulk simply severed the connection.

The New Team
"Well, we're not the '." "We've got some hitters." "They're good. They're not a team." "Let's beat 'em into shape."

- Steve Rogers and Natasha Romanoff

With the Ultron Offensive finished, Romanoff returned to the New Avengers Facility with the rest of her teammates. With her plan to run away with Banner having failed, and Banner missing in action, she had nothing else but to remain a superhero. She joined Captain America in co-leading the second incarnation of the Avengers, featuring Scarlet Witch, War Machine, Vision and Falcon.

Attack of Ultimo
"I remember you saying Fury once tasked you with doing a psych evaluation on Tony Stark–" "You had to remind me of that. Keep your guard up."

- Steve Rogers and Natasha Romanoff

HYDRA collected many of the parts of the destroyed Ultron Sentries and took them to an undisclosed location in Eastern Europe, where they used the parts to create the Ultimo and then used it to attack a small village. Romanoff joined the Avengers to an attack on the giant robot and together, they managed to destroy Ultimo.

Attack on the IFID Headquarters
"Looking over your shoulder should become second nature." "Anyone ever tell you you're a little paranoid?" "Not to my face. Why, did you hear something?"

- Black Widow and Falcon

Romanoff was on a mission in Lagos with Captain America, Scarlet Witch, and Falcon, where they were waiting to ambush Crossbones. Romanoff was sitting at a cafè with Maximoff, observing the area. When Redwing scanned a garbage truck, it was revealed to be at maximum capacity; Romanoff realized that the truck was a battering ram. The team then moved out to the IFID Headquarters where the truck had gone to. Rumlow, having retrieved the biological weapon, escaped the building with his henchmen. Romanoff gave chase on a motorcycle. She defeated Rumlow's agents with relative ease, but was grabbed by Rumlow himself, her Black Widow's Bite ineffective against his armored suit. Rumlow, claiming that his allegiance was no longer to HYDRA, threw Romanoff into a truck containing two of his agents, tossing a grenade inside and closing the roof. Romanoff incapacitated the agents and escaped the truck when the grenade blew. Rumlow gave the chemical to one of his agents and ordered them to split up, letting the Avengers chase them around Lagos. While Rogers fought Rumlow, Romanoff and Wilson pursued the agents. Romanoff reached the agents and held them at gunpoint; however, one of them threatened to drop the chemical. Romanoff killed one of the agents as the Redwing drone killed the other. Romanoff caught the vial before it hit the ground, thanking Falcon as she left the area. Though Falcon insisted that she thank the drone, Romanoff refused. They battle ended with a blast that accidentally caused by Maximoff, which killed several civilians.

Sokovia Accords
"If we have one hand on the wheel that can still steer." "Aren't you the same woman who told the government to kiss her ass a few years ago?" "I'm just... I'm reading the terrain. We have made some very public mistakes."

- Natasha Romanoff and Sam Wilson

While recovering from the the mission at Lagos, the Avengers were presented with the Sokovia Accords by Thaddeus Ross, which would put them under the direct command of a panel of the United Nations. Much to the shock of her comrades, Romanoff agreed with Tony Stark and was willing to agree to the terms of the Accords. She then called Clint Barton and asked if he would sign the Accords, but he claimed he had retired rather than sign. On her way to Vienna, where the Accords would be amended, she stopped at Saint Luke's Cathedral, where Steve Rogers had attended the funeral of Peggy Carter. He asked her who else had signed the Accords, so she replied that Stark, James Rhodes and Vision had all signed. She asked Rogers if he would reconsider his decision to not sign the Accords, saying that the Avengers should stay together regardless of how. He, as she expected, still refused and she admitted she was there as a friend to support him as he mourned the loss of Carter.

Vienna Conference
"I know how much Barnes means to you. I really do. Stay at home. You'll only make this worse for all of us. Please." "Are you saying you'll arrest me?" "No. Someone will if you interfere."

- Natasha Romanoff and Steve Rogers

In the conference at Vienna, Romanoff met T'Challa, who thanked her for supporting the Sokovia Accords. She also met his father, T'Chaka; to him, she gave her condolences for the death of the Wakandan citizens in Lagos. During the conference, a bomb was activated, killing T'Chaka. The authorities suspected that Bucky Barnes was responsible for the bombing from security tapes showing the man responsible. Outside the building, Romanoff apologized for T'Challa's loss and promised him that the task force would catch Barnes, but T'Challa said that he would kill Barnes himself. Steve Rogers called her and asked if she was fine and Romanoff responded positively, asking Rogers to stay out of the case with Barnes, or he might make things worse. However, Rogers insisted that he should be the one who to bring Barnes in since he would not die by trying it. He hung up the phone, and Romanoff knew he went to defend Barnes.

Winter Soldier's Escape
"We're seriously understaffed." "Oh, yeah. It would be great if we have a Hulk right about now. Any shot?" "Do you really think he would be on our side?"

- Natasha Romanoff and Tony Stark

Steve Rogers, Sam Wilson, T'Challa and Bucky Barnes were captured by the the Joint Counter Terrorist Centre, and were brought to the agency headquarter in Berlin. There, Romanoff told Rogers that what he had done had made things worse. In a meeting hall, Romanoff, Rogers, Wilson, Stark, and Sharon Carter watched Bucky's interrogation by Theo Broussard. However, Rogers began to suspect the psychiatrist was involved somehow with the setup of Barnes. During Barnes' psychological assessment, a power failure occurred. Barnes freed himself and tried to escape; however, Romanoff, Tony Stark and Sharon Carter engaged him. After which Stark and Carter were subdued by the Winter Soldier, Romanoff engaged him personally. Romanoff was strangled by Barnes. As he attempted to finally kill his enemy once and for all, Romanoff claimed that at least he recognized her from their last encounter during the Battle of Washington, D.C. until T'Challa saved her in the nick of time. However, Barnes escaped, but she and Stark knew Barnes was most likely with Rogers, who, along with Wilson, had also escaped custody. Thaddeus Ross gave Stark thirty-six hours to bring them in. Stark asked Romanoff if Hulk could assist them, but Romanoff knew that even if he was here, he would probably not be on their side. To get the fugitives in time, Romanoff approached T'Challa to ask for his help, promising she would help him find Barnes.

Clash of the Avengers
"You know what's about to happen. Do you really wanna punch your way out of this?"

- Black Widow to Captain America

Black Widow, along with Iron Man, War Machine, Vision, Black Panther, and Spider-Man confronted Captain America, Hawkeye, Falcon, Scarlet Witch, Ant-Man, and the Winter Soldier at the Flughafen Leipzig-Halle. She asked Rogers if he wanted to punch his way out of the situation knowing what was about to happen, but he did not surrender. When Falcon found the Quinjet, the rest of Captain America's team ambushed them and the two teams clashed. Black Widow found herself fighting against Ant-Man who was hesitant to hurt her which she told him not to stress about as he didn't stand a chance against her. As the two began to fight, Black Widow started to finish him off, but Ant-Man was able to shrink and tried to restrain her. However, Black Widow freed herself by shocking him with her bite causing him to be temporarily knocked out. Later, Captain America threw a fire truck which was also enlarged by Ant-Man's size-altering disk at Iron Man's team which Black Widow successfully avoided. Stark helped her get up and she asked him if fighting was part of his plan, and he responded that he had planned to go easy on Rogers but was now going to change it up.

Fighting Former Comrades
"This isn't going to end well."

- Black Widow

Iron Man then flew Black Widow across where the rest of Iron Man's team were and the two teams then faced and ran towards each other while Black Widow pointed out that it wasn't going to end well. As the two teams clashed again, Romanoff defeated Ant-Man easily and then proceeded to fight Hawkeye. As the two clashed and he threw her to the ground, she asked if they were still friends in the process which Hawkeye confirmed it by telling her it depended on how hard she hit him. Black Widow then got the upper hand, before Scarlet Witch intervened and knocked her out when she saw that Hawkeye was pulling his punches. After coming round, Black Widow then made her way to the hangar to guard the Quinjet. As Rogers and Bucky Barnes made it to the hangar, she stood in the way of them and realized that Rogers was never going to stop so she decided to follow her conscience and trust Rogers. She used her Taser Disks to stall Black Panther who was right behind them and was going to apprehend them. Rogers and Barnes escaped the airport in the Quinjet just as Black Panther got free from Black Widow's Bite. As the two watched Rogers and Barnes fly away, Black Widow told Black Panther that she had said to him that she would help him to find Barnes and not to catch him.

On the Run
"T'Challa told Ross what you did, so, they're coming for you." "I'm not the one who needs to watch their back."

- Tony Stark and Natasha Romanoff

Moments before the end of the Leipzig battle, James Rhodes crashed on the ground due to Vision's misfire. In a hospital, Tony Stark approached Natasha and told her that his spine had been damaged. Stark was disappointed at her for her betrayal, claiming that she was still acting as a double agent. She replied that they hadn't dealt with Steve Rogers rightfully. Stark scoffed at her biases towards Rogers before informing her that T'Challa had told Thaddeus Ross of her betrayal, giving her a halfhearted warning that the government would come to arrest her before denouncing their friendship and commenting that betraying people was the only thing Natasha was good at. Insulted, she told him that she was not the one who needed to watch her back, and ran to go underground.

Months later from going on the run, Romanoff joined up with Rogers and Wilson. Romanoff, Wilson and Rogers were shortly afterwards met with by Nick Fury. After dying her hair blonde, Romanoff used her KGB contacts to track down a terrorist organization supplied with Chitauri fueled weapons in Syria. Infiltrating the terrorists, Rogers, Wilson, and Romanoff disabled the weapons and then left for Lebanon.

Attack on Vision
"We don't want to kill you. But we will."

- Black Widow to Corvus Glaive and Proxima Midnight

Nearly two years after the Avengers Civil War, Romanoff, Steve Rogers, and Sam Wilson received a call from Bruce Banner, who warned them about the threat of Thanos as well as the fact that Proxima Midnight and Corvus Glaive were hunting the Mind Stone. The three headed down to Edinburgh, Scotland to protect Vision from the Black Order. The three arrived just in time and fended off the Black Order members with great ease. They were able to overpower the two and Black Widow even severely injured Glaive. After which Falcon arrived and subdued Proxima Midnight, who was dueling both Rogers and Romanoff at the same time, Romanoff watched as he held Mindnight and Glaive at gunpoint. Romanoff then claimed that the Avengers did not want to kill them but they would, Midnight taunted Romanoff that they will never get the chance again before retreating to their Q-Ship. They then decided to head back to the New Avengers Facility to try to help Vision, who was also severely injured.

Reuniting with Banner
"Hi Bruce." "Nat.""

- Black Widow and Bruce Banner

Arriving at New Avengers Facility, Black Widow and the rest were greeted warmly by James Rhodes. Thaddeus Ross, present at the compound via a holographic video call, ordered Rhodes to arrest her, Steve Rogers, Sam Wilson, and Wanda Maximoff, but he disobeyed the order, cutting off the call. As Rhodes welcome them back, Bruce Banner emerged, having been missing for over two years. Black Widow greeted Banner while Wilson commented that the meeting was awkward. Banner then warned the Avengers about Thanos's threat, informing them that Thanos recently obtained both the Power and Space Stone during the Massacre of the Xandarians and the Attack on the Statesman, as well as the fact that Thanos has an enormous army ready to invade Earth. When asked about the others, Romanoff revealed to Banner that Clint Barton and Scott Lang were both on house arrests due to their involvement in the Avengers Civil War. Romanoff then listened as Vision suggested that he would sacrifice himself so as to destroy the Infinity Stone within him, only for Rogers and Maximoff to protest his statement. Vision instead reminded that Rogers was willing to sacrifice his life. Banner related back to Tony Stark's creation of J.A.R.V.I.S. and Ultron, suggesting that they could remove the stone imbedded within Vision without killing him. Rogers then claims to know one place capable of doing that, Wakanda.

Arrival at Wakanda
Romanoff and the Avengers arrived to the Golden City in Wakanda where they were greeted by T'Challa and the Dora Milaje. Rogers also reunited with Bucky Barnes, who had recently been cured of his HYDRA programming. The Avengers then met Shuri, who explained how she planned on removing the stone from Vision.

Battle of Wakanda
"Where's your other friend?" "You will pay for his life with yours. Thanos will have that Stone."

- Black Widow and Proxima Midnight

While the Avengers listened to Shuri's method, Thanos' army attempted to breach Wakanda's shield but was repulsed, forcing them to land outside the shield perimeter. Assembling the Avengers and the Wakandan armed forces to oppose them, Black Widow joined Steve Rogers and T'Challa in talking to Proxima Midnight and Cull Obsidian at the shield boundary. Black Widow inquired where Corvus Glaive was; Midnight intimated that he was dead. Midnight and Obsidian then initiated the Battle of Wakanda as they proceeded to released their army of Outriders. A great battle commenced after which T'Challa ordered the Dora Milaje to open up their defenses. The Black Order and Outriders swarmed the battlefield, attacking the Avengers. At one point, the Avengers became overwhelmed by the Outriders. However, the team and the Wakanda army were saved by the arrival of Rocket Raccoon, Groot, and Thor, who recently obtained his new weapon, Stormbreaker, from Nidavellir. The battle continued with the Avengers gaining the upper hand against Thanos's army. After facing off against the Outriders, Scarlet Witch was subdued by Midnight and was about to kill her, when Black Widow and Okoye intervened, preparing to face off against the alien warrior. Black Widow managed to fend off Midnight's attacks and then proceeded to fight back, outnumbering her. However, they were soon overwhelmed by Midnight's strength, and Romanoff was knocked out whilst Okoye was thrown to the ground. Midnight then approached a subdued Black Widow and put a blade to her. When Midnight went to finish off Black Widow, only barely holding her back, Scarlet Witch used her powers to restrain Midnight and launch her into the path of one of Thanos' war machines, killing her, resulting in some of her blue blood being splattered across her face. Romanoff, lying on the floor commented that Midnight's blood was gross before getting up and continuing to fight against Thanos's army. The Avengers then located Vision in a forest who prompted Scarlet Witch to destroy the Mind Stone within him while Romanoff and the Avengers awaited Thanos's arrival. Once Thanos finally arrived on Earth, Black Widow tried to stop him from obtaining the Mind Stone, but found that she and her allies were hopelessly outmatched by Thanos's use of the Infinity Gauntlet. While War Machine, Black Panther, Okoye, Bruce Banner, Falcon, and Winter Soldier were blasted away by the Power and Space Stones, Black Widow was subdued by Thanos who used the Reality Stone to form stone pillars to trap her, watching as Thanos claimed the Mind Stone. As Thanos united the six Infinity Stones, however, Thor impaled him with the Stormbreaker. Moments later, however, Thanos snapped his fingers and wiped out half of the life in the universe. Despite being weakened by a fatal blow from Thor's Stormbreaker, Thanos transported to Titan II, leaving Black Widow as one of the survivors of the genocide. She had freed herself from Thanos' prison as she and her remaining allies could do nothing but accept their defeat.

Meeting Captain Marvel
"We don't even know what this is." "Fury did. You tell me the second you get a signal. I wanna know who's on the other end of that thing."

- Bruce Banner and Natasha Romanoff

Following the Battle of Wakanda, Romanoff, along with Steve Rogers, James Rhodes and Bruce Banner, returned to the New Avengers Facility. The Avengers sought out to hunt Thanos, using deep-space scans and satellites, only to have no results. Having discovered the Transmitter Pager in Atlanta that Nick Fury had activated prior to his death, the Avengers bypassed the pager's battery in order for it to continue to send out its signal. As Rogers and Romanoff were witnessing reports on the aftermath of the Snap, Rhodes, who was monitoring the pager, informed the pair and Banner that the pager had stopped transmitting the signal. Rogers requested that they reboot the pager and resend the signal, only for Banner to respond that they had no idea what the signal was for. As Romanoff explained that Fury knew whom the signal was for and that she wanted to know who it was as well, she came face to face with Captain Marvel herself, who demanded to know where Fury was.

Ambush on Thanos
"This is going to work, Steve." "I know it will. Because I don't know what I'm going to do if it doesn't."

- Black Widow and Captain America

Twenty-three days after the Snap, Captain Marvel returned from her mission to find Tony Stark, carrying Benatar towards the New Avengers Facility. The Avengers, along with Pepper Potts stood outside and witnessed Stark exit the ship, along with Nebula. They all then gathered inside where Romanoff informed Danvers and Stark of the Snap and the effects that have occurred since. As they continued to talk about Thanos, Stark began to get angry because of the encounter he had with Thanos alone. However, due to being in a weak state, he collapsed so Bruce Banner tended to him while the others waited. When Danvers decided to go out and find Thanos on her own, Romanoff stopped her, informing her that they work as a team. Nebula then joined the conversation and informed them of Thanos' location, Titan II, where Rocket Raccoon told them of a power surge that occurred two days ago. They then began to discuss going after Thanos, where they planned to retrieve the Infinity Stones and bring everyone back, something that Romanoff felt they owed to those who were gone because of the Snap. As they continued to discuss the plan, Danvers told them that they would be successful because they had her this time, causing an annoyed War Machine to retort back at her. As she claimed that there were many other planets in the universe which did not have a team like the Avengers, Thor, who had been silent for all of this, got up, and summoned Stormbreaker to prove she was worthy. Danvers did not blink and Thor exclaimed his fondness for her. With all the Avengers on board with the plan, they all suited up and boarded the Benatar. A team of Captain America, Black Widow, Thor, Captain Marvel, Nebula, Banner, Rocket and War Machine all made their way to Titan II by making a jump through space. Rocket asked them not to throw up on his ship, having learned that they have never been to space. When they arrived at the planet, Captain Marvel exited the ship to do recon while the others waited. Black Widow saw Captain America look at his compass, and reassured him that the plan was going to work, to which he responded by saying he wouldn't know what to do if it didn't. Captain Marvel then returned and updated the Avengers that it was only just Thanos on the planet. They then began their ambush, with Captain Marvel bursting into his home, placing him in a headlock. Bruce Banner in the Iron Man Armor: Mark XLIX quickly joined her, restraining the Infinity Gauntlet, with War Machine holding Thanos' other Arm. Thor then arrived and sliced off Thanos' left hand with Stormbreaker, releasing the Gauntlet and causing great pain to the Titan. Captain America, Black Widow, and Rocket Raccoon then entered the hut, and they were all shocked when they saw that the stones were no longer in the gauntlet. Under interrogation, Thanos revealed that his most recent usage of the Infinity Stones had been to destroy them, ensuring that he could not be tempted to use them again and that the Snap could not be undone. The Avengers initially believed Thanos to be lying, so Romanoff demanded the location of the Infinity Stones, but Thanos assured them they were gone and that he was nearly killed because of it. Nebula addressed that while her adoptive father was many things, he was not a liar. Thor then cut off Thanos' head, killing him. He then left, leaving a feeling of despair amongst them all.

Keeping her Family Together
"This channel is always active, so if anything goes sideways, anyone's making trouble where they shouldn't... comes through me."

- Natasha Romanoff to the Avengers

Losing all hope on bringing everyone back, over the next five years, each Avenger eventually moved on from this, Tony Stark starting a family, Steve Rogers holding support group meetings, Thor rebuilding Asgard on Earth and Bruce Banner becoming a combination between his two sides. However, being alone all her life until she was a part of the Avengers, which she saw as her family, Romanoff continued the team, with Carol Danvers, Rocket Raccoon, Nebula, James Rhodes and Okoye acting as members, operating on a bigger scale than they used to, helping reform the world back to normal after the Snap. In 2023, Romanoff held a meeting with the Avengers, who were all at different locations, where she was provided with updates on what they were each doing. When the meeting concluded, Romanoff reminded them that the channel would always be open if there was ever a problem. Rhodes stayed on the channel, telling her that he was in Mexico, still following Barton, telling her that after witnessing the scene he had left, he was not sure if he even wanted to find Barton. However, Romanoff asked if he could keep looking anyway. When he left, Romanoff began to cry over the thought of her best friend until Rogers entered the room. Rogers, noticing his friend was in distress, attempted to comfort her, but she stopped him from telling her to look on the bright side by threatening to hit him with her sandwich. When Rogers sat down, the two began to discuss moving on, something Rogers had been telling others, but was not reciprocated by them. Romanoff pointed out that if she didn't lead the Avengers, no one would, something Rogers believed might be fine. However, Romanoff told him that she used to have nothing in her life until she became an Avenger, giving her a family and making her better. She then addressed that even though people are gone, she was still trying to be better, which Rogers then stated that they both needed to get a life.

Scott Lang's Return
"Thanos happened, and I got stuck in there." "I'm sorry, that must have been a very long five years." "Yeah, but that's just it, it wasn't. For me it was five hours."

- Scott Lang and Natasha Romanoff

Suddenly, an alert appeared for the front entrance camera, so Romanoff opened it revealing Scott Lang to be standing outside. They then let him inside, where he asked them if they studied, which Romanoff said she was, only for conversation. Lang then told them about how he got trapped in the Quantum Realm five years ago due to the Snap. Lang then revealed that for him, it was actually five hours in the Quantum Realm. Rogers then tried to get Lang to clarify what he was saying, which was that time works differently in the Quantum Realm, but there is no way to navigate it. He proposed the idea to control the Quantum Realm, entering at one point in time and exiting out another. However, none of them knew how to handle this idea, so they decided to visit Tony Stark, who was living a normal life with his family. They drove to his house and sat down with him to discuss Lang's idea, but Stark was opposed to it. Romanoff told Stark that they had to try, but he continued to refuse. Stark then left them when his daughter came out, causing them to leave without his help. Rogers then suggested another brain they could use to help them, Bruce Banner.

Time Travel
"You are kidding, right?" "I have no idea, we're talking about Time Travel here. Either it's all a joke or none of it is."

- Natasha Romanoff and Bruce Banner

The three then met up with Banner in a diner, who explained to Lang his new transformation into a mixture of Banner and the Hulk. They were then interrupted by some kids who wanted a picture with Banner, and when they left, Banner informed them that Time Travel was outside his area of expertise, but Romanoff reminded him that he was able to merge his two personas, something that seemed impossible at one point in his life. He then agreed to help them, and they returned to the facility to work on navigating the Quantum Realm to ensure time travel. They then began to test time travel, with Lang wearing the Quantum Realm Exploration Suit. When Banner mentioned not wanting something to go wrong and have Lang stuck in the past, Romanoff said he was joking, but Banner was unsure of that, due to the uncertainty of the experiment. Banner set the machine up to send Lang back a week and bring him back in ten seconds. They then activated the machine, which sent Lang into the Quantum Realm, and when they brought him back, he was a child. Banner then tried to fix this error by sending him back, but when he returned he was an old man, followed by a third try which brought Lang back as a baby. Banner then told Romanoff to kill the power on his signal, which successfully returned Lang to his normal age.

Reuniting with Clint Barton
"We've found something... a chance, maybe." "Don't." "Don't what?" "Don't give me hope." "I'm sorry I couldn't give it to you sooner."

- Natasha Romanoff and Clint Barton

After their failed experiment, Stark arrived at the facility having figured a way to perform time travel successfully. He then agreed to help them, and they began to get the Avengers back together. Romanoff went to Tokyo in search for her best friend, Barton, having discovered that is where he was. She made her way to Barton's location, to be confronted with him ruthlessly murdering Yakuza boss Akihiko. When Barton became aware of her presence, he told her that she should not be there, which she replied neither should he. Barton told Romanoff he had a job to do, but she told him that it wouldn't bring his family back. She then revealed their plan to bring everyone back, but he told her to not give him hope, something he had lost which Romanoff wished she could have given him sooner. She then held his hand to comfort him and the two returned to the facility.

Creating A Plan
"Guys, if you pick the right year there are three stones in New York." "Shut the front door."

- Natsha Romanoff and Bruce Banner

With all the Avengers assembled once again, they began to work on creating the machine as Scott Lang prepared to test it. They finished the machine, but Clint Barton ended up being the one to test it, as Lang was not ready. They all watched as Barton stood on the machine and then went into the Quantum Realm. A few seconds later he was brought back, and Romanoff checked up on him. After telling her he was fine, he showed her a baseball glove he retrieved, revealing that their experiment had worked.

With the means of transportation achieved, the team then began to discuss the Infinity Stones' history. They started with the Aether, watching on as Thor told them about it, but started to get off topic due to him not being in control of his emotions. They then moved onto the Orb, which Rocket Raccoon informed them was on Morag when Peter Quill stole it in 2014. Nebula then told them about the Soul Stone, which Thanos retrieved on Vormir by sacrificing her sister. Romanoff, Tony Stark and Bruce Banner then discussed the Time Stone, which they told her Doctor Strange had, and he lived in New York. Romanoff then realized that at one point in time, there were three stones in New York: the Time Stone, the Space Stone and the Mind Stone. With this point being brought up, they were then able to complete their brainstorm for the Time Heist and plan out who was going where. Romanoff and Barton would go to Vormir in 2014, along with James Rhodes and Nebula, who were going to Morag, Stark, Steve Rogers, Banner and Lang were going to New York in 2012, and Thor and Rocket were going to Asgard in 2013.

Retrieving the Soul Stone
"Who are you?" "Consider me a guide to you and to all who seek the Soul Stone." "Oh good, you tell us where it is, then we'll be on our way." "Lieblich, if only it were that easy."

- Black Widow and Stonekepper

The Avengers all then suited up in their Advanced Tech Suits and made their way to the platform, where Captain America gave them a speech about everything that had led up to that moment and how this was their only opportunity to change what had happened. Bruce Banner then activated the machine, as Romanoff told them she would see them in a minute, and they all were transported to the Quantum Realm, where they each traveled to their designated time. Black Widow, Hawkeye, War Machine and Nebula all successfully arrived in 2014 on Morag, where they enlarged the Benatar and waited for Nebula to lower the Benatar's Space Pod. Black Widow and Hawkeye then boarded the Benatar and said goodbye to War Machine, who asked them to watch over each other. They then departed Morag and headed to Vormir, to retrieve the Soul Stone. As they traveled to Vormir, which Nebula had set the coordinates for, the two best friends enjoyed the sight of space travel, laughing with each other, as Hawkeye mentioned that they had gone through so much since being S.H.I.E.L.D. agents, mentioning their mission in Budapest. They soon arrived at the planet, which amazed Hawkeye, saying that what they were doing would be awesome if not for the circumstances. They then made their way through the planet, climbing up the mountain, which they found to be exhausting. Black Widow pointed out the physical effort of their mission by stating that Rocket, who she referred to as a raccoon, wouldn't have had to climb a mountain, which Hawkeye stated that technically he was not a raccoon, but she didn't care. When they made it to the top of the mountain, they were greeted by the Red Skull who alarmed them, causing them to draw their weapons at him. Schmidt, who had revealed Black Widow's father's name, informed them that he was a guide for those seeking the Soul Stone, so Black Widow demanded that he show them where it was. However, he informed that it is never that simple. They learned that the stone was at the bottom of the cliff, and that they had to make a sacrifice of what they love for the Soul Stone.

Self-Sacrifice
"Then I guess we both know who it's gotta be." "I guess we do." "I'm starting to think we mean different people here, Natasha." "Last five years I've been trying to do everything to get to right here, that's all it's been about, bringing everybody back."

- Hawkeye and Black Widow

Upon learning about the price to pay for the Soul Stone, Black Widow and Hawkeye took a moment to let the severity of the situation sink in. Black Widow sat down as she contemplated doing whatever it takes to retrieve the stone, while Hawkeye voiced his disbelief. She then remembered how Nebula told them that Thanos killed Gamora on Vormir, meaning the sacrifice was legitimate. They then repeated what Captain America had said before their mission "whatever it takes", before accepting that one of them needed to sacrifice themselves for the stone. Hawkeye decided that he would make the sacrifice, holding Black Widow's hand to comfort her in their final moments. However, she then reciprocated the same gesture, making him realize that she intended on sacrificing herself. They then argued over which one it should be, neither wanting to willingly let the other die. Black Widow attempted to make her case, saying this is what she had been working towards all these years, and that she did not want Hawkeye to die. However, Hawkeye told her he should do it, as he saw himself as too far gone, which she assured him that he is more than his worst moments. However, when he told her that she should not try and give him a chance, she responded to the fact that he did for her when they first met. They then took a moment to embrace each other's friendship, resting their heads on one another, until Hawkeye took her off guard and threw her down so he could sacrifice himself. He told her to tell his family, when they were brought back, that he loved them. However, Black Widow gained the upper hand and threw him down, deciding to make the sacrifice herself. She hit him with her Black Widow's Bite, causing him to get shocked. As she made a run for the cliff, Hawkeye ripped off the Taser Disk, drew his bow, and fired an explosive arrow near her, causing her to be thrown away from the cliff. He then made it for the cliff and jumped off, but Black Widow also jumped and grabbed him, shooting a grapple and attaching it to him, so he wouldn't fall, forcefully sacrificing herself. However, Hawkeye was able to grab onto her, but could not pull her up, without both of them falling. He got mad at her for stopping him from sacrificing himself. She asked him to let her go, knowing that there was no other way, but he couldn't bring himself to do it. He desperately tried to get her to not do it, not letting go of her, as he did not want his best friend to die, but she felt the exact same and forced him to let go. Hawkeye cried as he watched Black Widow fall to her death, helpless to do anything else. With the sacrifice being made, Hawkeye then obtained the Soul Stone.

Legacy
"You know, I wish there was a way... that I could let her know... that we won. We did it." "She knows."

- Clint Barton and Wanda Maximoff All the Avengers then returned to 2023, believing that the mission had been a success, until they saw Barton fall to his knees as Romanoff did not return. Banner asked him about her whereabouts, but he was too saddened to respond. However, they were able to understand that Romanoff had died during the mission, causing their initial celebration to perish. The original Avengers all gathered outside to mourn the loss of their friend, Stark asking if she had any family they had to inform, which Rogers noted that they were her family, something she had told him earlier.

When Thor questioned why they were acting like she was dead, believing that they can bring her back with the stones, Barton told them that it couldn't be undone. Barton then became angry over the death of his best friend, stating that it was meant to be him who made the sacrifice. Banner then agreed that she couldn't be brought back, so he told them that they wouldn't let her death be for nothing, so they began constructing a Nano Gauntlet to control the Infinity Stones.

Banner used the Gauntlet to reverse the Snap, successfully restoring the lives of the individuals who lost their lives five years ago, though Romanoff could not be revived despite Banner's attempt. After Stark's funeral, Barton spoke to Wanda Maximoff beside the lake at the Stark Residence. Barton told her that he wished there was a way for him to let her know that they were successful and her sacrifice meant something. Maximoff comforted him by saying that she knew, as well as Vision.

Personality
"The truth is a matter of circumstance. It's not all things to all people, all the time. Neither am I." "That's a tough way to live." "It's a good way not to die, though."

- Natasha Romanoff and Steve Rogers

The entirety of Romanoff's character is hard to distinguish based on how she lies and tricks people for a living. She was capable of convincingly portraying friendly and flirtatious, timid, vulnerable and scared. For the most part, she was a level-headed, strong-willed and independent woman. Romanoff normally maintained a controlled, almost emotionless persona to keep whatever she was thinking a secret unless she was around people she absolutely trusts. Although she was more than willing to rush into deadly battle and other unnerving missions for S.H.I.E.L.D., she was not completely fearless, as she was visibly frightened of Hulk. However, she was no longer afraid of him due to falling in love with Bruce Banner.

Though a very serious agent, Romanoff was by no means stuffy and has a sarcastic sense of humor, which mostly surfaces when she was with Captain America or Hawkeye, both of whom she was comfortable around. Romanoff was very smart and loyal which was displayed when she made good on the debts she owed Barton and Rogers (saving the former from Loki's mind control and trying to protect the latter during a highway assault). While tough and at times ruthless, she was still a good person and can be quite heroic in her own right. These qualities are usually brought out by her other Avengers, mainly her missions with Steve Rogers. And no matter how injured she was in battle, Romanoff will go out her way to make sure bystanders are out of harm's way (keeping several S.H.I.E.L.D. agents away when Banner was transforming into Hulk, helping Hawkeye evacuate civilians when the Chitauri attacked Manhattan, and risking her life to make sure innocent people weren't shot by the Winter Soldier when he was chasing her). Her close loyalty to both Rogers and Barton was shown in the Avengers Civil War, as she was willing to aid their faction despite being forced to go on the run from the United Nations afterward. As a result of her childhood, she considered the Avengers her family, being desperate to keep them together when the Sokovia Accords were due to be signed and was affected when Tony Stark denounced her as a friend and made it clear he would not help her in the future. She was further shocked and saddened when Barton following the loss of his family became more ruthless and violent when she encountered him in Tokyo.

Romanoff was also very close with Clint Barton's family, especially with his and Laura Barton's only daughter, Lila, being the only member of Avengers who knew of their existence. Romanoff was genuinely affectionate with the child, hugging her the moment they reunited and sweetly commended the little girl on the drawing she made. They originally named their youngest child after Romanoff prior to them discovering that it was, in fact, a boy, thus naming him Nathaniel instead, with Romanoff humorously referring to the unborn child as a "traitor". This was further proven in Vormir where she refused to let Clint sacrifice himself, knowing how much he meant to his family and vice-versa and died instead because she had little to lose.

Romanoff was sterilized as a rite-of-passage for her graduation from the training she underwent in the Red Room under the supervision of Madame B. This event deeply affected her, as she regretfully told Banner of the so-called advantages of the procedure.

Despite her lifestyle of espionage and operating within the shadows, Romanoff's adaptability influenced her opinions on the Sokovia Accords. Realizing the difference between S.H.I.E.L.D. and the Avengers with many of their activities seen in the light of day amongst the public, Romanoff wanted to appease public opinions by signing and also that she didn't want conflict with her close friends and teammates like Barton and Rogers. This care for Captain America eventually caused Romanoff to betray Stark's team and assist their escape so they could clear Barnes' name, eventually becoming a fugitive because of this.

Abilities
"You are mind-blowingly duplicitous. How do you do it? You just tear things out? You're a triple imposter. I've never seen anything like it. Is there anything real about you?"

- Tony Stark to Natasha Romanoff

"You lie and kill in the service of liars and killers."
 * Master Spy: Romanoff was a dangerous secret agent highly skilled in espionage, stealth, disguise, infiltration, and demolitions. Her talents and years of experience have enabled her to reach a high ranking as a special agent of S.H.I.E.L.D. Romanoff is well versed in internal destabilziation and was soon deemed a threat to global secuirty because of this. She often resorts to seducing men to obtain her goals while working undercover, such as when she posed as an assistant to evaluate Tony Stark for the Avengers Initiative. Romanoff's skills were so legendary that Nick Fury created a Lie Detector that he hoped she could not deceive.
 * Master Martial Artist: Romanoff was one of the best fighters in the world, having been trained from a young age in the Red Room and S.H.I.E.L.D. in her later life as a top operative. During her time in the Red Room, she was seen using her martial arts to defeat a grown man by swinging his head into the corner of a desk, proving how formidable she was even when she was young. She was extremely skilled in the field of martial arts, having mastered arts such as, , , , , , multiple styles of , , and with her batons. Romanoff has efficiently taken down many enemies, such as multiple Hammer Industries security guards, Georges Batroc's armed pirates, several members of STRIKE, Ultron Sentries, and even Chitauri aliens. She was skilled enough to be able to defeat a mind-controlled Hawkeye, maintain the upper hand against Ant-Man, and even hold her own against the much stronger Winter Soldier, though he was able to bring her down in the end. Black Widow also proved capable of defeating numerous Outriders and managed to compete with Proxima Midnight alongside Okoye, even managing to disarm her with her electrical baton, holding her off long enough for Wanda to kill her. In addition, she had enough skill to stab Corvus Glaive using Proxima Midnight's Spear.
 * Spear Mastery: Romanoff shows great skill in the use of a spear in close combat, she was seen wielding a Chitauri staff to battle the Chitauri. She was also skillful enough to use Proxima Midnight's spear to almost kill Corvus Glaive. Romanoff also combined her batons into a staff to battle Proxima Midnight, using it to defend and attack simultaneously.
 * Staff Mastery: Romanoff possessed tremendous skill in using a staff, demonstrating her prowess during the Battle of Wakanda to fight against Proxima Midnight.
 * Master Acrobat: Romanoff was highly skilled in incorporating gymnastics and acrobatics into her fighting style as she battles opponents. During her fight within Hammer Industries Headquarters, Romanoff used these skills to defeat the guards. During the Chitauri Invasion, she got to ride a Chitauri Chariot by using her acrobatics to commandeer it.

- Loki to Black Widow

"She's fluent in French, Italian, Russian, Latin."
 * Master Assassin: Romanoff was notorious in the art of assassination, considered to be one of the most dangerous assassins in the world. She was known to have killed many people during her time serving the KGB and S.H.I.E.L.D.. During her time in the Red Room, Romanoff was trained to kill without remorse and was seen demonstrating her sharpshooting skills on a live captive, showing no emotion as she killed him.
 * Master Marksman: Romanoff was a very accurate marksman skilled in sharpshooting. During the Battle of Washington, D.C., Romanoff would have shot the Winter Soldier through his eye if he had not been wearing his protective goggles. She had also been trained from a young age in the art of sharpshooting, as she was seen practicing on targets, making several headshots in quick succession.

- Tony Stark "The person who wrote this is slightly smarter than me. Slightly."
 * Multilingualism: Romanoff was fluent in Latin, Russian, English, French, German, Chinese, Italian, and various other languages.
 * Gifted Intellect: Romanoff's intellect seemingly put her on par with Steve Rogers and Clint Barton. She possessed the ability to quickly process multiple information streams (e.g., threat assessment) and rapidly respond to changing tactical situations. Romanoff also possessed a vast knowledge of human anatomy, displayed by her often using joint locks and hitting enemies in the weakest parts of their bodies; for example the crotch, stomach, armpits, and the head. Her prodigious skill from her years of training also allow her to predict her opponents' plans of attack as well, such as when she was able to save herself, Captain America, and Falcon from being shot by the Winter Soldier by predicting the order in which he would shoot at them through the roof of their car. Victoria Hand has even stated that Romanoff does not usually require extraction teams on S.H.I.E.L.D. missions and is resourceful enough to make her own escape.
 * Master Interrogator: Romanoff was able to trick Loki into telling her about his plan to use Hulk against the Helicarrier to bust him out of his cell. She was able to do a "reverse interrogation"; while she seemed to be in danger, in truth, she was getting all the information she wanted to know.

- Natasha Romanoff to Steve Rogers


 * Expert Hacker: Romanoff could hack into most computer systems without tripping any firewalls or security. She used this talent to hack into Hammer Industries mainframe and help James Rhodes regain control of the War Machine Armor and enabled him to help Stark fight the rest of the attacking Hammer drones, and again to access the location of Camp Lehigh from the USB Steve Rogers received from Nick Fury.
 * Pilot: Romanoff was a skilled pilot, capable of flying a Quinjet with ease.

Weapons

 * Black Widow's Bite: Electroshock weapon that can deliver powerful electrical discharges from two bracelets worn by Romanoff. When the Chitauri forces invaded Earth during the Battle of New York, she used the Widow's Bite to electrocute several enemy troops by jamming her charged fists into them. Romanoff used the Widow's Bite to take out a pirate guarding the Lemurian Star ship's engine room. Romanoff acquired a more powerful version of the Black Widow's Bite from Tony Stark, which causes the piping in her suit to light up and glow. She made use of her bite during the Avengers Civil War. She zapped Ant-Man with her bite, sending her miniaturized opponent flying away, and later used the bite to cover the escape of Captain America and the Winter Soldier by using Taser Disks fired from her bite to hold off Black Panther.
 * Black Widow's Batons: Electroshock weapons that can deliver powerful electrical shocks to incapacitate her targets. Romanoff used the batons to take down dozens of Ultron Sentries with a combination of her weapons and martial arts mastery and later employed these weapons during the Avengers Civil War, although not charged with electricity. She once again utilized her batons to battle the Black Order and the Outriders and was able to combine them to form a staff; she kept these batons in a holster worn on her back.
 * : During her training with the Red Room, Romanoff trained with this gun, shooting it in quick succession while alternating her shooting arm, and being forced to use it against living targets.
 * : Romanoff's original weapon of choice. She carried it when she went to stop Ivan Vanko at Hammer Industries Headquarters, but chose not to use it against the security guards inside the complex.
 * : Romanoff took a Heckler & Koch USP Compact from one of the guards at Hammer Industries Headquarters. She dual-wielded it along with her Walther PPK/S when she stormed inside the room where Ivan Vanko was supposed to be, only to find it empty.
 * : Romanoff replaced the Walther PPK/S for a pair of Glock 26 handguns as her weapon of choice. She had one of them concealed in the abandoned house in India where she staged a meeting with Bruce Banner, and then used both her firearms shortly after to fight the Chitauri army during the Battle of New York. Romanoff continued to used them during her missions with S.H.I.E.L.D., killing some of Georges Batroc's pirates during a mission to rescue the Lemurian Star, and later during a shootout against the Winter Soldier in Washington, D.C., managing to shoot and damage his goggles and forcing the Soldier to remove them. During the Battle of Sokovia, Romanoff resorted to the use of her handguns to shoot point-blank some of the Ultron Sentries. She still carried them during the Clash of the Avengers, but she kept them holstered so as not to harm her former allies.
 * : The Glock 19 pistol is the standard sidearm carried by STRIKE. Romanoff was able to obtain one of them when she posed as Councilwoman Hawley inside the Triskelion, using it to threaten Alexander Pierce. She also retrieved one of these guns hidden beneath the bar of Avengers Tower in order to shoot at the Iron Legion drones hijacked by Ultron. She used it to great effect, shooting one Iron Legion drone in the head while running up the stairs with Bruce Banner for cover, and continued to fire at another before Steve Rogers destroyed it with his shield.
 * : Romanoff managed to obtain this gun from one of the mercenaries working for Crossbones who attacked the Institute for Infectious Diseases in Lagos. When Romanoff grabbed the gun, one of the mercenaries threatened to release the biological weapon they had just stolen. She used it to quickly kill one of the mercenaries while Redwing killed the other, managing to secure the biological weapon.
 * ' with a ': A fully automatic carbine and the standard weapon used by S.H.I.E.L.D. Strike Team members, outfitted with a grenade launcher. Romanoff took the weapon that the Winter Soldier had been using and shot a grenade at him, forcing him to make his escape before he could kill Steve Rogers in Washington, D.C.
 * Chitauri Staff: Romanoff took one of the staves used by the Chitauri army when they invaded New York City and effectively used it against them as both a ranged and melee weapon.
 * Proxima Midnight's Spear: Romanoff used this during the Attack on Vision against Corvus Glaive.

Uniform

 * S.H.I.E.L.D. Uniform: Black Widow's first uniform was a bluish-black catsuit. It zipped up the front and had fingerless gloves with a S.H.I.E.L.D. logo on the shoulders. It had two belts, one of which had a red hourglass symbol on it and the other serving as a utility belt. It also had a thigh holster.
 * Avengers Uniform: Her second uniform was a slightly modified version of her earlier one, made of smooth gray fabric. The red hourglass was brighter and the belts were slightly different. The only major difference was the inclusion of built in wrist tasers.

 * Advanced Tech Suit: This suit was designed in order to time travel through the Quantum Realm safely. It is a white, red, and black suit that materializes around the wearer's regular clothes when time travel is required and disappears when no longer in use. It has size-shifting adaptability down to subatomic levels and a wrist gadget that allows for displacement through time and space.

Other Equipment

 * Taser Disks: Romanoff used two Taser Disks aimed at the feet of one the security guards at Hammer Industries Headquarters, paralyzing his legs to temporarily disable him.
 * Flash Bombs: Romanoff used two of these Flash Bombs to blind some of the security guards at Hammer Industries Headquarters, easily dispatching them afterward.
 * Garrote: Romanoff carried a garrote inside one of her bracelets, using it to deflect the blows of one of the security guards at Hammer Industries Headquarters, and later to strangle him until he lost consciousness.
 * : Romanoff took one of the pepper sprays carried by Hammer Industries security guards, and used to dispatch the last guard before attempting to arrest Ivan Vanko.

Fury was eventually forced to use it in response to the Snap. It was later found and used by the Avengers.

Vehicles

 * Quinjet: Romanoff has used a Quinjet for transportation to travel around the world and take out threats during active missions as an agent of S.H.I.E.L.D. and as a member of the Avengers. She usually co-pilots the Quinjet, controlling the weapons that are built into its systems.
 * Chitauri Chariot: During the Battle of New York, Romanoff realized that they needed to close the portal after containment proved to be overwhelming. Captain America helped her to jump on a Chitauri Chariot to quickly ascend to Stark Tower while the rest of the Avengers continued to battle the Chitauri.
 * Jeep: During the Attack on the HYDRA Research Base, Romanoff and Barton used a Jeep to fight the HYDRA soldiers and move around faster. When all the Avengers regrouped to attack the HYDRA soldiers, Romanoff crashed the Jeep as she and Barton jumped out to continue fighting on foot.
 * Motorcycle: Romanoff used a motorcycle during her missions with the Avengers prior to its destruction during the Battle of Seoul.
 * Truck: Romanoff drove a truck with a plow attached to its front in order to run over many Ultron Sentries so she could rendezvous with her fellow Avengers at the citadel.

 * Avengers Tower: After the collapse of S.H.I.E.L.D., Tony Stark decided to fund the Avengers, redesigning Stark Tower as a new headquarters for the team. After retrieving Loki's Scepter, the Avengers held a party at the tower which fell under attack by a newly created Ultron. The Avengers then proceeded to search for Ultron in the tower, going through their files until they came across Ulysses Klaue.
 * Clint Barton's Homestead: When Romanoff was spared by, and eventually became best friends with, Clint Barton, she was one of the few people to know of his family. She would develop a close relationship with the family, forming an aunt-like relationship to his children, often visiting his home, including when all the Avengers were defeated by Ultron.
 * New Avengers Facility: After the Ultron Offensive, the Avengers relocated their base of operations to a facility upstate. There, Romanoff and Steve Rogers would train the new lineup of Avengers, as well as use it as their place of residence.
