Nebula

"There are little girls like you across the universe who are in danger. You can stay with us and help them." "I will help them by killing Thanos."

- Gamora and Nebula Nebula is a Luphomoid assassin, an adopted daughter of the intergalactic warlord Thanos and adopted sister of Gamora. As the right-hand woman of Ronan the Accuser during his and Thanos' quest to retrieve the Orb, she helped him fight the Guardians of the Galaxy during the Battle of Xandar. Fleeing the battle after a fight with Gamora, Nebula was soon captured by the Sovereign and handed back to the Guardians. She escaped and helped Taserface lead the other Ravagers in a mutiny against their former leader Yondu Udonta before leaving to find and kill Gamora. After forgiving and helping her sister alongside the Guardians during the Battle on Ego's Planet, she left in a ship to pursue a revenge mission against Thanos.

Nebula was eventually captured by Thanos, however, and used as a bargaining tool to convince Gamora to reveal the location of the Soul Stone. Escaping and then pursuing Thanos to Titan, Nebula learned that Thanos had killed Gamora and aided both the Guardians, Doctor Strange, Iron Man and Spider-Man during the Battle of Titan. Despite their efforts, they failed to stop Thanos from obtaining the Infinity Stones, which he then used to wipe out half the universe's population. Nebula was among those who survived but was left alone in space while departing from Titan to Earth with Stark in Benatar until they are found by Captain Marvel, who brought the pair to the New Avengers Facility in New York.

Now on Earth, Nebula joined the Avengers, participating on the Ambush on Thanos. Following Thanos' murder at the hands of Thor, she spent the next five years traveling throughout the world with Rocket Raccoon under Natasha Romanoff's command. In 2023, she joined her fellow Avengers in the Time Heist, traveling to Morag in 2014 with War Machine to retrieve the Power Stone, creating an alternate timeline in the process. However, she was kidnapped and replaced by her alternate past self, who took her place and returned to the future. Teaming up with the Gamora from alternate 2014, Nebula killed her past self and participated in the Battle of Earth. In the aftermath of Stark's sacrifice during the battle to use the Infinity Stones to eliminate Thanos and those loyal to him, Nebula attended his funeral to honor him. Nebula, along with Thor and Rocket, left the Avengers and rejoined the Guardians of the Galaxy once again.

Trained for Thanos
"My father would have Gamora and me battle one another in training. Every time, my sister prevailed. My father would replace a piece of me with machinery, claiming he wanted me to be her equal. But she won. Again, and again, and again, never once refraining."

- Nebula

As an infant, Thanos invaded Nebula's home planet, murdering her whole family yet taking her to train her as merciless warrior devoted to his service. While Nebula greatly despised her other adopted siblings, she formed a genuine bond with Gamora to the point that they began to truly consider each other as sisters. Throughout her childhood, Nebula trained to be a Galaxy-class killer under the tutelage of Ronan the Accuser. Nebula would often train alongside Gamora and Korath.

Thanos regularly had Nebula spar with Gamora to test their strengths with Gamora winning every match. Every time Nebula lost, Thanos would upgrade her to try and make her Gamora's equal. Nebula grew to resent Gamora for never letting her win causing Thanos to torture her.

One training scenario on the arboreal world of Dervani saw Nebula and Gamora pitted against each other in a competition to retrieve a data ingot for Ronan. The girls sparred on the surface, leading to Gamora throwing Nebula off a cliff, severely injuring her and requiring multiple cybernetic replacements in order for her to live. Upon reaching adulthood, Nebula and Gamora served Thanos under the command of Korath.

On a mission to locate the Orb on Praxius IX, inside of one of the Cloud Tombs of Praxius, Nebula went in without waiting for Gamora and fell into a trap. Ensnared by an impenetrable Laser Thorn Energy Net, Nebula found herself at the mercy of the inhabitants and needed to be rescued by Gamora. Never one to tolerate failure, Thanos ordered Gamora to leave Nebula behind, with only a sharp blade to free herself. Nebula was forced to amputate her own arm in order to escape the netting.

Family Conquests
"Father's found an Infinity Stone." "Where?" "On a planet called Morag."

- Gamora and Nebula

Under Thanos' orders, Nebula and Gamora participated in the cleansing of half of the Korbinites. During the skirmish, she managed to kill a few soldiers. However, she is attacked by a enemy soldier who threw a stray grenade in her direction, causing her to fall. Fortunately, Nebula was saved at the last minute by Gamora, who killed the enemy soldier. Extending a helping hand, Nebula scoffed at claimed not to have needed help, only for Gamora to remind her that she always needed her help. The two daughters of Thanos then regrouped back on the Q-Ship after their mission was completed. Gamora learned about Thanos' success in locating the Power Stone on Morag and shared that information with Nebula, who then began to stress to Gamora that their adopted father would finally put his plan into effect to hunt for the Infinity Stones. However, Gamora assured Nebula that Thanos only found one of the stones at the moment and is yet to uncover the others. As Nebula continued to fret over Thanos' plan, Thanos suddenly appeared on their Q-Ship as he wiped off blood from his double-edged sword. As he approached his daughters, Thanos informed the two that his ally in the Kree Empire, Ronan the Accuser, had located the Power Stone on Morag and was therefore planning to dispatch his two daughters to Ronan's Kree ship — the Dark Aster — to oversee the retrieval of the Power Stone for him and deliver it to him. Gamora, however, pointed out that Ronan would be displeased with them being at his side during his search for the Power Stone. Thanos then warned the two that Ronan's alternate was death if they refused, noting that his obsession with the Kree-Nova War clouded his judgements. Nebula then bowed down to Thanos and promised to not fail him, to which Thanos responded that she won't fail him.

Following Ronan's Orders
"You think I don't know? You would keep me from advancing! You would have Ronan tell father only Gamora furthers his great plan!" "I will keep you alive!" "Compassion? What would Ronan say to that?"

- Nebula and Gamora

Nebula and Gamora left the Q-Ship and were dispatched to the Dark Aster, belonging to Ronan the Accuser, who made a deal to retrieve the Orb for Thanos so he would, in turn, destroy Xandar. As Korath the Pursuer returned to the Dark Aster, having returned from Morag, Nebula updated Ronan that he arrived back after which he concluded with the ritualistic execution of a Nova Corps officer sent to negotiate the peace deal. Nebula, Gamora, and Ronan the Accuser then listened to Korath as he reported that he had failed to retrieve the Orb on Morag, thanks to Star-Lord's intervention, but informed the trio that, through his various sources, he believed that the Ravager would be selling the Orb to the Broker on Xandar. Ronan, ranting on how badly he wanted to destroy Xandar and wipe out all the Nova Corps as an act of vengeance for what the transgressions they committed against the Kree Empire and being responsible for the deaths of his family, tasked Nebula to retrieve the Orb from Star-Lord on Xandar and bring it to him on the Dark Aster once she recovered it. As Nebula told him it would be an honor, Gamora resisted, reminding Ronan that he would have to stand in front of Thanos and report his failure if the Orb wasn't brought to him. Nebula, slightly offended by Gamora's statement, arrogantly claimed to be the daughter of Thanos just as Gamora. However, Ronan, considering Gamora's warning, instead sent Gamora to Xandar, threatening her with a severe punishment if she failed, despite the fact that she had never failed Thanos. When they left the meeting, Nebula confronted Gamora and they had a brief argument where they tried to break each other's fingers. Nebula accused her sister of now attempting to become Ronan's favorite and they argued over who was the superior killer. When Nebula mentioned that the screams of her victims could be heard across the galaxy, Gamora replied that it was because she took too long to kill them before walking away from Nebula.

Meeting With Thanos
"Thanks, Dad, sounds fair. This is one fight you won't win. Let's head to the Kyln."

- Nebula to Ronan the Accuser

Ultimately, Nebula and Ronan realized through their sources that Gamora had been captured by the Nova Corps. However, through communication with The Other, the two learned from that she had betrayed him and instead planned to sell the Orb to a third party. The Other then demanded the two travel to the Sanctuary and discuss the issue with Thanos in person as Ronan's alliance with the Mad Titan was at risk. On the Sanctuary, Nebula repaired her cybernetic arm while Ronan argued with The Other, berating him and Thanos for claiming that she betrayed their cause, reminding the two that she lost the battle against Star-Lord on Xandar, despite being a deadly assassin. Nebula then witnessed as Ronan snapped The Other's neck, and she heard Ronan asking Thanos to understand the severity of the situation at hand. Thanos, unfazed by his servant's death, responded by threatening Ronan's life if he failed again. Thanos then claimed that Ronan's obsession with the Kree-Nova War bored him. Nebula then heard Thanos call Gamora his "favorite daughter", which irked her. Thanos promised to honor their agreement and supply Ronan with a formidable army, but threatened to "bathe the starwars in his blood if he failed again. As they left, Nebula thanked Thanos for the meeting and assured Ronan that he would not win a fight with her father.

Cleansing the Kyln
"Send Necrocraft to every corner of the quadrant. Find the Orb. Any means, any price." "And this place?" "The Nova can’t know what we’re after. Cleanse it!"

- Ronan and Nebula After Ronan and Nebula left the Sanctuary, they followed The Other's lead and arrived at the Kyln, only to discover that Gamora, Star-Lord, and three other individuals had escaped from the prison with the Orb in their possession. As a result, the Sakaarans took over the prison and interrogated the hostages in an attempt to gain information on Gamora's next destination. On the second floor, Nebula tortured a Nova Guard to gather more information. However, she suddenly received a message on her cybernetics that the Nova Corps were on their way to defend the prison. As they were leaving Ronan ordered Nebula to send their Necrocraft across the galaxy to search for Gamora through any necessary means. Nebula then asked him what to do with the prisoners, to which he responded to cleanse the prison of all the guards and prisoners in an attempt to prevent the Nova Corps from realizing what they were after.

Skirmish on Knowhere
"You are a disappointment, sister. Of all our siblings, I hated you least." "Nebula, please. If Ronan gets this Stone, he'll kill us all." "Not all. You will already be dead."

- Nebula and Gamora

Following the orders of Ronan the Accuser, Nebula and Korath continued their search for the Orb across the galaxy onboard the Dark Aster, until they received a message from Drax the Destroyer telling them it was on Knowhere where they went to recover it. Upon arriving onboard Necrocraft and their army of Sakaarans, they were spotted by Gamora and her new team, who escaped into a Mining Pod while Nebula gave chase with her small army. While Ronan began fighting with Drax, whose wife and daughter had been killed by the Kree, Nebula lead a squad of soldiers in fighters to chase Gamora across Knowhere, while fighting off Star-Lord and Rocket Raccoon who defended their ally. Eventually, Gamora was forced to head into deep space which shut down her pod. Nebula destroyed her ship, despite her pleas, and leaving her for dead in space and retrieved the Orb.

Betraying Thanos
"After Xandar, you're going to kill my father? You dare to oppose me? You've seen what he's turned me into. You kill him and I will help you destroy a thousand planets."

- Nebula and Ronan

After the Skirmish on Knowhere, Nebula returned to the Dark Aster and presented Ronan with the Orb. Both her and Korath the Pursuer were present when Ronan the Accuser contacted Thanos and updated the Mad Titan on his success on Knowhere. When Thanos told Ronan to bring the Orb to him, Ronan ignored his demands and instead informed Thanos that he was aware that the Orb contained one of the six Infinity Stones, which shocked both Korath and Nebula. To Thanos' horror, Ronan ripped the Orb open to reveal the Power Stone, which he observed while Korath warned him that he should not double-cross Thanos as he was the most powerful being in the universe. Ronan assured him that with the Power Stone, he was more powerful than the Mad Titan. Ronan then proceeded to harness the stone's power and attached it to his Cosmi-Rod, as he was strong enough to wield its power. Ronan then announced that he would destroy Xandar with the Power Stone, ending the existence of the Nova Corps and the status of the Kree-Nova War before personally threatening to kill Thanos shortly after. When the Mad Titan ended the transmission, Nebula offered her total loyalty to Ronan should he succeed, swearing to help him destroy a thousand planets.

Battle of Xandar
"The starboard kern has been breached! We have been boarded!" "Continue our approach." "But the Nova Corps have engaged!" "None of that will matter once we reach the surface."

- Nebula and Ronan the Accuser

When they arrived near Xandar, a fleet of Ravagers lead by Yondu Udonta and Star-Lord engaged them. Nebula then warned Ronan of their presence. The fleet fired a blot of flame to disguise their moves, but Nebula saw that they had dived under the ship and she ordered all their fighters to destroy the ships. Once they received word that the side of the ship had been breached, Nebula tried to convince Ronan the Accuser to retaliate but he refused, stating that his focus was to land on the planet's surface so he could finally destroy it. Nebula considered Ronan's plans and ordered the Sakaarans to seal the security doors so the Guardians of the Galaxy could not reach Ronan. Deciding to take matters into her own hands, Nebula took a squad of soldiers with her to engage the attackers before shutting the door, locking in Ronan. While the Sakaarans protected the ship, Nebula decided to confront the Guardians of the Galaxy herself. When Star-Lord, Gamora, Rocket Raccoon and Drax breached the ship, Nebula confronted them. As Nebula began to insult her former sister, she was silenced when Drax shot her with a rocket, sending her flying backward and damaging her body while allowing the Guardians to continue on their mission.

Duel against Gamora
"Sister! Help us fight Ronan! You know he is crazy!" "I know you're both crazy."

- Gamora and Nebula

The shot fired by Drax the Destroyer caused Nebula's entire body to be damaged, but her cybernetic implants helped to repair her within moments, twisting her arm and jaw back into place. Once she was repaired Nebula began to fight Gamora, using her electrified batons against Gamora's Godslayer. During their fight against each other, the side of the ship was suddenly torn apart by an explosion as the Battle of Xandar between the Yondu Ravager Clan and the Sakaarans continued on. During their fight, Gamora attempted to unlock an armored door to assist the Guardians of the Galaxy, however, Nebula did all she could to delay this action. Eventually, Nebula managed to gain the upper hand by disarming Gamora and then using her batons to electrocute Gamora, nearly killing her. However, Gamora regained her strength and knocked her outside of the hole in the Dark Aster and leaving Nebula hanging onto the edge of the hole. As Nebula hung hundreds of feet above Xandar's surface, with her hand trapped onto a spike, Gamora tried to convince her to fight against Ronan the Accuser, claiming Ronan was crazy. But Nebula refused, citing they were both crazy and cut off her cybernetic hand. However, instead of falling from the sky to her death, she landed on top of a Ravager's M-ship. Nebula then threw the pilot out and took control of the ship before flying it far away from the battle.

Captured by the Sovereign
"I understand she is your sister?" "She is worth no more to me than the bounty due for her on Xandar."

- Ayesha and Gamora

Sometime later, Nebula was arrested by Ayesha and the Sovereign for trying to steal expensive Anulax Batteries. Six months after the Battle of Xandar, the Guardians of the Galaxy were present at the palace and were given custody of Nebula as a reward for killing the Abilisk during the Battle of on Sovereign, thus ending its reign of terror on the Sovereign people. As Nebula was brought before Ayesha and the Guardians and unmasked, she exchanged a threatening stare with Gamora, who just looked at her calmly. When Ayesha claimed to have known that she is her sister, Gamora claimed that Nebula was worth nothing to her and was only taking custody of her to hand her over to the Nova Corps on Xandar to receive their bounty. Before leaving, Ayesha questioned Quill about his ancestry and hinted that his father was of a unique species, thus prompting him to wonder who his father really was. While still locked up Nebula continued to mock Gamora for joining the Guardians before demanding that she be fed some fruit, which Gamora refused to give her, claiming the fruit was still not ripe enough. As Gamora claimed to hate her, Nebula reminded her that she betrayed Ronan the Accuser and was deemed a hero by the Nova Corps for saving Xandar. She then threatening to kill her and exact revenge upon her. However, as Gamora arrogantly claimed that she would spend the rest of her life in a Xandarian prison wishing she had the opportunity to kill her, the Sovereign fleet attacked after Rocket Raccoon stole the batteries, Nebula was almost sucked out of the ship, but escaped her restraints. As the Guardians berated Rocket for his actions, Nebula called the Guardians a bunch of "idiots". Her hands remained handcuffed and she demanded to be released after they crashed on Berhert to fight whoever was in the unidentified craft, with Nebula surviving the crash with the others.

Meeting Ego
"You're leaving me with that fox? He's not a fox. Shoot her if she does anything suspicious. Or if you feel like it."

- Nebula and Gamora

Nebula witnessed Ego's revelation that he was Star-Lord's father. The next day she was left in the Milano with Rocket Raccoon and Groot whilst Gamora, Quill and Drax the Destroyer went with Ego and Mantis. Before Gamora left with the others to Ego's planet, Nebula asked if she was being left with Rocket Raccoon, mistaking his species for a fox, to which Gamora responded that he was not a fox. Gamora then gave Rocket an official order to shoot her if she attempts to escape or if he simply feels like it.

Attack on Berhert
"Your friend… There's too many of them. He needs my help. If you care about him… You need to get me out of these bonds. They are going to kill him!"

- Nebula to Groot

After Star-Lord, Gamora, and Drax left Berhert and accompanied Mantis and Ego to his living planet, Rocket was ambushed by the Ravegers led by Yondu Udonta, having been dispatched by Ayesha to capture the Guardians of the Galaxy. Nebula, overhearing the commotion and witnessing the situation, managed to trick Groot into freeing her so that she could seemingly rescue him from the Ravagers. Groot, unaware of her sinister intentions, released her from her restraints. As an uprising began amongst Yondu Udonta's clan after which he revealed his intentions of double crossing Ayesha and taking the Anulax Batteries himself, she managed to persuade Groot to release her before intervening. The fight got to a point where Yondu summoned his Yaka Arrow on all his Ravagers as they were threatening to depose him. While Rocket tried to pacify the situation, Nebula came from behind and shot Yondu's fin before he could kill anyone who opposed his rule, thus rendering him unconscious before proceeding to shoot Rocket in the chest with the Electric Blaster. The Ravagers looked from Nebula's direction in shock as she announced herself that she was their new leader, and she began to take a bite out of the fruit before spitting it out and claiming it was not ripe.

Ravager Mutiny
"I thought you were the biggest sadist in the galaxy." "That was when Daddy was paying my bills. The Priestess wants to kill the fox herself. And he has bounties on his head in at least twelve Kree provinces. I assure you, I am not as easy a mark as an old man without his magic stick or a talking woodland beast."

- Nebula and Taserface

She was taken aboard Yondu's ship witnessing the mutiny led by Taserface, in which he executed associates of Yondu Udonta who opposed Taserface's new rule and still declared their allegiance to Yondu. As a vexed Taserface prepared to execute Rocket Raccoon who was mocking his name, Nebula announced that there would be no more killings that day, having been fed up with the mutiny. When Taserface questioned her if she was the deadlies woman of the galaxy, Nebula responded that she was under Thanos' tutelage, but Gamora stole that mantle from her time after time after defeating her in combat. She then demanded ten percent of the bounty Ayesha had placed on the Guardians of the Galaxy as well as 'some other things'. Nebula was given a new cybernetic hand by Kraglin Obfonteri as well as an M-ship. When asked what she would do with the bounty, she informed him of her upbringing with Thanos and how he had 'upgraded' her every time she lost a sparring match to Gamora. Nebula explained that after she kills Gamora she would use her ten percent to buy every ship she could to kill Thanos. A bewildered Kraglin wished her luck before Nebula left the Eclector and traveled to Ego's Planet so she could finally kill Gamora.

Fight with Gamora
"I'm not the one who just flew across the universe just because I wanted to win!" "Do not tell me what I want!"

- Gamora and Nebula

Nebula flew to Ego the Living Planet and began firing at Gamora, who was meditating in a flower field. Gamora fled from Nebula, hiding in one of the caverns. However, Nebula redirected her course, pursuing her into caverns, causing the ship to be destroyed. Nebula became trapped in the M-Ship as Gamora started shooting at the ship. Sensing that the ship was about to explode, Gamora rescued Nebula before the entire ship erupted into flames, which sent them to the ground. Both sisters, injured, got up and Nebula immediately attacked her. A shocked Gamora then continued to fight her until Nebula finally got her into a choke hold. Instead of finishing her sister off, Nebula let her go and finally expressed excitement at the fact that she finally bested her in combat, only for Gamora to claim that she saved her life and that the match was unfair, and, therefore, she did not truly win the match. Nebula, claiming that she just wanted a sister, expressed her anger at Gamora for always beating her in combat, which resulted in Thanos 'upgrading' her every time she lost. The pair formed an uneasy alliance, and explored their surroundings in the caverns. As they walked through the caverns, they discovered a large pile of bones, seemingly confirming that Ego had sinister intentions. Observing the chamber, Nebula claimed that they had to get off the planet before Ego killed all of the Guardians of the Galaxy.

Battle on Ego's Planet
"This is gonna hurt!" "Promises, promises."

- Yondu Udonta and Nebula

Nebula and Gamora rushed back to the palace and confronted Mantis who agreed to help them. Along with Drax the Destroyer, they burst into the main hall to find Ego attacking Star-Lord before a ship piloted by Yondu Udonta and Rocket Raccoon crushed him. Nebula agreed to help as the Guardians were her only ride off of Ego. During the Battle on Ego's Planet, she wired the ship up to her cybernetic arm to provide power to the lasers which electrocuted her and caused her great pain but destroyed the Sovereign fleet in the process, which pursued the Guardians on Ego's Planet with the final intent on killing all of them for stealing the Anulax Batteries shortly after the Battle on Sovereign. When the ship was destroyed she joined the Guardians of the Galaxy in the heart of the planet to continue the fight Quill's sadistic father and prevent him from killing all of them. When Ego attacked, Nebula saved Gamora from falling to her death with the sisters climbing back up to the fight before being trapped and suffocated in organic matter. When Star-Lord took control, they were both released, which allowed them to reach the ship piloted by Kraglin Obfonteri. However, Gamora, upon asking Rocket Raccoon where Quill was, ultimately realized from Groot that Quill had decided to stay on the planet to allow the Guardians to leave. Before Gamora could react, Rocket shot her unconscious, unwilling to lose another friend. However, Star-Lord reigned victorious over Ego and the Guardians set off the explosion in Ego's brain, thus killing him. At the last moment, Nebula witnessed as Yondu Udonta decided to sacrfrice his life for the life of Peter's. The two embraced each other, with Yondu lamenting that he had always been his true father as he raised him to be a Ravager and treated him as an equal. Star-Lord returned to the ship, and he, Nebula, and the others mournfully watched as Yondu suffocated and died in space.

Reconciling with Gamora
"You will always be my sister."

- Gamora to Nebula

Nebula prepared to leave during Yondu Udonta's funeral. Despite Gamora's attempts to persuade her into joining them, she chose to leave and try to kill Thanos instead and prevent other people's daughters from sharing the same fate she has suffered. The two sisters reconciled and hugged before Nebula departed.

Futile Vengeance
"Some time ago, your sister snuck aboard this ship to kill me. Very nearly succeeded."

- Thanos to Gamora

In the years following the battle with Ego, Nebula attempted to kill Thanos by sneaking onto the Sanctuary II. She nearly succeeded, but was caught by her former master and put in a torture chamber, where her cybernetic parts were pulled apart from her body, causing immense pain. When Thanos captured Gamora after she attempted to stop him on Knowhere, he brought her to Nebula to force her to reveal the location of the Soul Stone. Thanos began torturing Nebula again, tearing the cybernetic parts from her body using the Infinity Gauntlet, in an attempt to get the information from Gamora. Gamora at first resisted, claiming she didn't know the location of the Soul Stone. Thanos, who knew that Gamora was lying, stated that he made her a strong assassin, but never taught her to lie, and he played a clip from Nebula's memory using a projector in her cybernetic parts. The clip showed Gamora having a conversation with Nebula, in which Gamora stated that she found the map to the Soul Stone, but decided to burn it to ash to prevent Thanos from finding it. After commenting on how poor of a liar Gamora was, Thanos started ruthlessly torturing Nebula again, until Gamora gave in and told Thanos the location of the Soul Stone: Vormir. The two then departed to Vormir to retrieve the Soul Stone. When Thanos and Gamora left, one of his Chitauri henchmen began putting Nebula back together. Seizing a quick opportunity, she killed the henchman and made a quick escape from her captivity. Nebula contacted Mantis, requesting her and the rest of the Guardians of the Galaxy to meet her on Titan, knowing that the members of Thanos' Black Order would meet him there once they found the Time Stone and Mind Stone. Getting inside a Necrocraft, she flew to Titan with the desire to enact her plan to kill Thanos.

Battle of Titan
"You should have killed me!" "It would have been a waste of parts!"

- Nebula and Thanos

When she arrived on Titan, the Guardians of the Galaxy were fighting alongside Iron Man, Spider-Man, and Doctor Strange in a battle with Thanos. Nebula crashed the Necrocraft into Thanos, then exited the spacecraft and attacked him with an electrified staff. She furiously told him that he should have killed her, to which Thanos coldly remarked that it would have been a waste of parts. As she continued to fight him, Nebula demanded to know where Gamora was. Although she fought ferociously, Nebula would prove to be no match for Thanos and was quickly thrown back into a pile of rocks. Eventually, the Guardians and Avengers then restrained Thanos, with Mantis successfully putting him into a passive state. Star-Lord then asked Thanos where Gamora was. Nebula got up and approached her restrained father whose thoughts and consciousness was pacified by Mantis. As Star-Lord inquired about Gamora's whereabouts, Thanos began to weep in front of a shocked Nebula, who deduced that Gamora had not returned with Thanos from their trip to Vormir upon obtaining the Soul Stone. Nebula informed this to Star-Lord, and Thanos confirmed that it was true by muttering that he had to kill her. Stricken with grief, Star-Lord began to attack Thanos' face with his blaster in a state of blind fury, weakening Mantis' grip. Despite Iron Man's attempts to hold Star-Lord back, it was too late; Thanos was able to break free and overpower the Avengers and the Guardians. He regained control and after escaping, Thanos removed the souls of Drax, Star-Lord, and Nebula with a burst of energy from the Soul Stone. Thanos then pulled chunks of Titan's moon down from orbit, causing a meteor shower to engulf the planet. Nebula, Drax and Star-Lord all began to lifelessly float in the air due to Titan's fluctuating gravity and the intense impact from the meteors. Nebula was saved by Spider-Man, who had also saved Star-Lord, Drax the Destroyer, and Mantis restored their souls to their bodies. After successfully besting Iron Man and Doctor Strange, Strange gave Thanos the Time Stone so that he would spare Stark's life, saying that the Avengers were now in the end game. Thanos then left Titan in pursuit of the final Infinity Stone, the Mind Stone, on Earth.

Thanos' Victory
"He did it..."

- Nebula

While he was on the Earth, Thanos had successfully got the Mind Stone and, using the full Infinity Gauntlet, snapped his fingers, wiping out half of all sentient life in the universe. Nebula, having survived the Snap, grimly watched as the Guardians of the Galaxy as well as Doctor Strange, and Spider-Man had all perished and faded into ash as a result of Thanos' victory. Nebula told Tony Stark that Thanos had succeeded in his mission, with visible despair on her face. She then sat on the ground as she grieved Gamora's death and Thanos' victory along with Iron Man, who sat in despair at the fact that half of the universe was killed by the Snap and he could do nothing about it. With her own ship damaged, she joined Stark in commandeering the Benatar in order to leave Titan.

Trapped in Space
"You don't need to do that. Because uh... you're just holding position. Oh yeah, that was close. That's a goal. We're now one apiece." "I would like to try again." "We tied up. Feel the tension? It's fun."

- Nebula and Tony Stark

The fuel cells of the Benatar had been damaged during the Battle of Titan, forcing Tony Stark and Nebula to work together to repair it. After succeeding in repairing the ship, Stark set a course for Earth. However, the ship only possessed forty-eight hours worth of fuel left, leaving the pair stranded in deep space with no help. Over the course of twenty-four days, they bonded and developed a friendly relationship, rationing their food, and water and playing games to pass the time. Nebula continued to provide medical assistance to Stark due to the stab wound he had received from Thanos during the Battle of Titan. Nearly a month later, their supply of oxygen began to run out and Nebula and Stark were aware that they most likely were going to die. Before, Tony sent a final transmission to Pepper Potts. Luckily, Captain Marvel showed up in front of Benatar, and she single-handily moved the stranded ship to Earth. Landing at the New Avengers Facility, Nebula reunited with Rocket Raccoon and the other Avengers, while Tony and Steve awkwardly encountered each other, with both claiming that they were defeated by Thanos during Infinity War. A disheartened Rocket asked about the status of the other Guardians of the Galaxy, only for her to solemnly look down, thus confirming to the surviving Guardian that the others perished during the Snap along with half of the universe.

Locating Thanos
"Don't bother. I can tell you where Thanos is. Thanos spent a long time trying to perfect me. And when he worked, he talked about his great plan. Even disassembled, I wanted to please him. I'd ask "where would we go once his plan was complete?". His answer was always the same: "To The Garden."

- Nebula and the Avengers Nebula and the Avengers regrouped in the meeting room where Natasha Romanoff went over the list of casualties of the Snap to both Tony Stark and Nebula which included T'Challa, Sharon Carter, Shuri, Erik Selvig, Sam Wilson, Bucky Barnes, Stephen Strange, Wanda Maximoff, and others. Steve Rogers then attempted to gain information on Thanos' current whereabouts by interrogating Tony, who had fought him on Titan. Instead, Stark and Rogers started to fight due to unresolved issues stemming from the Avengers Civil War. With Tony rehabilitating and resting in another room, the Avengers started to discuss Thanos's possible location. Nebula revealed Thanos's location- the Garden- as she elaborated upon Thanos fixing her in her youth to make her equally formidable as Gamora was. Nebula then joined the Avengers as they traveled to the Garden so they could use the Infinity Stones to resurrect every victim of the Snap. While they traveled, Rocket sarcastically told them not to throw up on his ship.

Ambush on Thanos
"The work is done. It always will be. I am inevitable." "We have to tear this place apart. He... he... he has to be lying." "My father is many things. A liar is not one of them."

- Thanos, War Machine and Nebula

Nebula then joined the Avengers as they traveled to Garden on the Benatar. During the trip, Rocket sarcastically instructed the Avengers not to throw up on his ship as none of them, except for Nebula, had been to space before. When they arrived to the Garden, Captain Marvel was dispatched to scout the entirety of the planet. After which she concluded that Thanos was alone in exile, the Avengers headed to Thanos' resting place, restrained him, and cut off his arm with the Infinity Gauntlet. Rocket Raccoon, who Nebula developed a bond with both having lost the little family they had managed to gain, then kicked Thanos' detached limb to discover that the stones are gone. Thanos explained that he actually destroyed the Stones prior to their arrival to ensure that the Snap remains permanent, mentioning that it had almost killed him when doing so. Many of the Avengers were skeptical of this, but Nebula said that while Thanos was many things, a liar wasn't one of them. Thanos confirms this by thanking Nebula for pointing that out and admitting that he was wrong to be too harsh on her. This enraged Thor who cut Thanos' head off in retaliation, which made some of the Titan's blood splatter on Nebula's face. Despite her hatred towards Thanos, Nebula was touched by his last words and mourned for him by closing his eyelids out of respect. She and the other Avengers were forced to accept the losses for the rest of their lives.

Helping the Avengers
"Yeah, we boarded that highly suspected warship Danvers pinged." "It was an infectious garbage scowl.""

- Rocket Raccoon and Nebula

In the five years after the Snap, Nebula continued to protect the universe as she served as an Avenger under Natasha Romanoff's command, helping maintain peace across the universe to help those who lost people to the Snap. She also changed her left superficial armor plating with bronze colored ones. Nebula returns to space with Rocket Raccoon using the Benatar and inspects a ship suspected of selling weapons, only for it to be a garbage scow. During a holo-conference, she voices her frustration at Captain Marvel for sending them into such a situation. At the conference's end, she and Rocket return to patrol, while Romanoff continues her conversation with War Machine, who informed her about a recent attack in Mexico in which members of a drug cartel were ruthlessly murdered by an unknown assassin. This eventually prompted her to locate Clint Barton.

Discussing the Infinity Stones
"Thanos found the Soul Stone on Vormir." What's Vormir?" A dominion of death, at the very center of Celestial existence. It's where... Thanos murdered my sister"

- Nebula and Natasha Romanoff

Following Scott Lang's return from the Quantum Realm and proposed the idea of the "Time Heist" to undo Thanos's actions, she and Rocket Raccoon returned to Earth following a summons from the Avengers about a plan to undo Thanos' snap. Arriving at New Avengers Facility, she came across Lang eating a taco, and as he claimed that Nebula looked awesome, she sarcastically transmitted a message on her earpiece to James Rhodes, advising him to be careful entering the landing zone, calling Scott an "idiot". The Avengers later regrouped in a debriefing room and discussed the history of the Infinity Stones. As such, the Avengers learned from Thor that the Aether- a manifestation of the Reality Stone- was formerly owned by the Dark Elves of Svartalfheim, but it was taken away by the Asgardians, who hid it in a secret chamber until Thor's ex-girlfriend Jane Foster uncovered it and became its next host. Through Rocket Raccoon, the Avengers also learned that the Power Stone was stolen by Star-Lord on Morag in 2014. When Natasha asked about the Soul Stone, Nebula solemnly stated that it was located on an isolated planet called Vormir, and she also proceeded to inform the Avengers that Vormir was the location from which Thanos murdered Gamora. As they tested the Advanced Tech Suit, Nebula adjusted the inner functions while Bruce Banner educated James Rhodes and Lang about time travel mechanics. Following a successful time jump, she along with the Avengers gear up with their suits, and aim for their targets, the Infinity Stones in the past. After reexamining the information about the Infinity Stones across their respective encounters, Banner, Tony Stark, Steve Rogers, and Natasha Romanoff managed to narrow down three periods where each stone are aligned with three small teams: 2012 with the Mind, Space, and Time Stones at the Battle of New York and the New York Sanctum; 2013 with the Reality Stone occupying Jane Foster on Asgard; 2014 with the Power Stone on Morag and the Soul Stone on Vormir.

Arriving on Morag
"We're not the only ones in 2014 looking for the stones." "Wait a minute, what are you talking about right now? Who else is looking for these stones?" "My father, my sister, and me."

- Nebula and War Machine

When the teams are assigned, Nebula teams up with War Machine, Black Widow, and Hawkeye to collect the Power and Soul Stone in 2014, creating an alternate timeline in the process. The four arrived on Morag hours before Peter Quill would have showed up to steal the Orb on Morag and would have been confronted by Korath the Pursuer. After enlarging the Benatar and the space pod, Nebula and War Machine were hurried by Romanoff and Barton who reminded them that they needed to speed it up. War Machine jockingly claimed that all of their complaints were not helpful to their mission. The four then proceeded to hug and they wished each other luck in obtaining the Power and Soul Stones before Romanoff and Barton departed for Vormir. Nebula and Rhodes observed as the two quickly left the desolate planet, with Nebula noting that she had supplied the Benatar with the coordinates for Vormir and that the two Avengers would only need to survive the jump point. While Black Widow and Hawkeye sojourned for Vormir to retrieve the Soul Stone, War Machine reviewed the plan and asked Nebula if they were supposed to wait for Peter Quill to arrive on Morag and allow him to lead him to the location of the Power Stone, to which Nebula responded that they should take cover. Nebula reminded him that there are others searching for the Stones. Namely Thanos, Gamora, and herself; as Nebula was still a fanatic of Thanos' grand plan in 2014.

Memories Intertwined
"Who was that?" "I don't know... My head is splitting... I don't know... " "Her synaptic drive was probably damaged in battle." "Shhh... Bring her to my ship"

- Gamora, Nebula, and Thanos

Meanwhile on the others side of the universe, 2014 Nebula is seen battling Korbinites as Thanos wages another cleansing for half of the species' population. She is bested by a stray grenade and rescued from an enemy soldier by 2014 Gamora, who extends a helping hand only to be smacked away. Perturbed by being helped, Nebula demands an explanation, only for her to relay that Thanos has found the Power Stone on Morag. The two return to one of Thanos' Q-Ships and discuss the prospect of him obtaining all six of the Infinity Stones and completing his plan. Suddenly, Thanos appeared in front of Nebula and Gamora, wiping blood off his Double-Edged Sword, and he informs them that Ronan the Accuser has located the Power Stone, and announces that he is planning to dispatch the two assassins to the Dark Aster to oversee the retrieval of the stone for him. When Gamora stated that Ronan would be disturbed by their presence, Thanos warned her that his alternative was death and that Ronan's obsession clouded his judgements. Stepping ahead of Gamora, Nebula bows before Thanos promising to return with the Stone when suddenly, her Synaptic Drive glitches and a hologram of War Machine appears before the gathering. Thanos, curious, orders Nebula to be examined by Ebony Maw on his ship.

Theft of the Power Stone
"Whoa, whoa, whoa, whoa...This is the part where spikes come out with skeletons on the end and everything..." "What are you talking about?" "When you break into a place called the temple of the Power Stone, there's gonna be a bunch of booby traps-- Okay. All right. Go ahead."

- War Machine and Nebula

Meanwhile on Morag, Nebula and War Machine observed as Star-Lord arrived on Morag to claim the Orb for himself while dancing to his Walkman. As the Ravager continued his dance, War Machine nodded his head in thought and commented on Quill being an idiot. Deciding to end the nonsense, War Machine intervened and punched Star-Lord, knocking him unconscious as Nebula looted his thief tools to enter the Temple Vault. As the two finally entered the shrine, War Machine, having seen too many movies, was hesitant to enter, urging Nebula be wary of traps, only for her to shake her head in annoyance, and she casually walked into the chamber, dismissing his fears of the imaginery booby traps. Exploring the Temple Vault, she located the Orb being protected by a force field. She approached it and reached in the pedestal, bypassing the incineration field and retrieved the Orb at the cost of her arm getting severly burnt. As War Machine witnesses her cyborg hand at its base mechanics, she remarks how she did not used to be like how she is now; a sentiment War Machine shares, following the airport battle in Germany with the Avengers Civil War. Synchronizing their Quantum Bands, War Machine activated his return beacon, but Nebula's could not as her network was connected with 2014 Nebula's network. Petrified, she attempted to press the button again, only for it to do nothing.

Captured By Her Past Self
"That's not me. It's not. I could never... I would never betray you. Never." "I know. And you'll have the chance to prove it."

- Nebula and Thanos

Connecting to the network, Future Nebula saw Ebony Maw examining 2014 Nebula's memory network, where he found a duplicate connection. 2014 Nebula is suspended upwards by Thanos on the Sanctuary II, with her memories being examined by Maw. As Thanos demanded him to show him her memory file, the member of the Black Order informed the incredulous Titan that her memory originated from another version of Nebula, nine years into the future- in 2023. Puzzled, Thanos inquired Ebony Maw about the current location of the future Nebula, to which Maw responded that she is currently located on Morag. A curious Thanos then asked Maw to scan her memories for files that pertained to the Infinity Stones. While watching a memory that was taken during the ambush on his original self, Thanos learned that the 2023 version of Nebula joined the Avengers as he recognized a few of its key members including Tony Stark and Steve Rogers. Proceeding with his demands, Thanos later instructed Ronan the Accuser and Korath the Pursuer to delay their search for the Power Stone as he wanted to abduct Nebula from the future. Thanos ultimately discovered that he completes the Snap in the original timeline. This accessed memory therefore struck him with the realization that the Avengers are the ones orchestrating the Time Heist with the intent of undoing the Snap, which he caused in their original timeline. After having discovered that he eventually dies at the hands of Thor four years later, Thanos acknowledged that he completed his destiny after which Gamora asked him what he did. Maw, while joyous for his master, prepares to execute Nebula for her future betrayal. Thanos, however, knew his daughter at this time is loyal to his grand plan, and spares her; he instead planned to use her for hijacking the Time Heist. Without hesitation, Thanos later instructed Maw to set a course for Morag so they could abduct the future Nebula.

Evil Nebula Strikes
"You disgust me. But that doesn't mean you're useless."

- Past Nebula to her future self

Awakening from her memory link, a horrified Nebula 2023 storms out of the Temple Vault and seeks refuge in the Benatar's Space Pod, before rushing to warn Hawkeye and Black Widow that 2014 Thanos and his forces are aware of their plans, and that he is planning to abduct her on Morag. However, she receives no response from the two Avengers and moments later, the Sanctuary II descends on Morag and tracks her shuttle. Nebula is later captured and interrogated by Thanos's forces. As Nebula is interrogated by her 2014 self, the younger takes offense to her future self for betraying Thanos' goals. But as the future Nebula tries to talk sense to 2014 Gamora, she is knocked down by her younger self. Threatening her with a knife, instead of killing or torturing her future incarnation, 2014 Nebula instead removes superficial armor plating to equip to herself, and hands Thanos the Pym Particle device to transport to the future. With her outward appearance identical to her future self and equipped with the Avengers suit, acting as a tether 2014, Nebula activates the beacon to jump to 2023. But as the Avengers were reeling from the revelation that Natasha Romanoff had to sacrifice herself for the Soul Stone, the past Nebula had to make herself scarce under a pretext of letting them grieve. As the Avengers come to terms, Tony Stark, Bruce Banner, and Rocket Raccoon construct their own Infinity Gauntlet, and as they debate who should use it, 2014 Nebula activates the Quantum Tunnel to summon Sanctuary II. However, at this exact moment, Bruce Banner uses the Nano Gauntlet to undo the Snap, therefore resurrecting every victim of the Snap. Despite this, the Sanctuary II was transported to the present, and Thanos proceeds to open fire on the New Avengers Facility, destroying the vast majority of it, which also separates the Avengersfrom each other. Approaching Thanos, 2014 Nebula is instructed by her adopted father to find the Nano Gauntlet and bring it to him while he waits to battle the Avengers.

Freed by 2014 Gamora
"Tell me something. In the future, what happens to you and me?" "I tried to kill you. Several times. But eventually, we become friends. We become sisters."

- Gamora and Nebula

Upon seeing the destruction Thanos laid down to claim the Nano Gauntlet, 2014 Gamora goes to an incarcerated 2023 Nebula, asking her about their future, remembering 2023 Nebula's cryptic message to her about her fate which pertained to Thanos finding the Soul Stone during on Vormir during the Infinity War. Nebula proceeds to inform Gamora that she tried to kill her and her soon-to-be friends on multiply occassions such as during the Skirmish on Knowhere and the Battle of Xandar. Soon after, Gamora receives an honest and heartfelt truth: it was her's genuine sisterly love and openness during Ego's Expansion that allowed Nebula in the future to become someone better, allowing the two to finally be like real sisters. Processing the information, 2014 Gamora extends her hand to the future Nebula, giving her confidence that they could still stop Thanos. 2023 Nebula accepts help that her younger self would reject in hubris.

Killing Her Past Self
"You can change." "He won't let me." "No!"

- 2023 Nebula, 2014 Nebula, and Gamora After the New Avengers Facility is destroyed, 2014 Nebula locates a fatigued Clint Barton who had just eluded and killed Outriders who were chasing him in the sewer systems. Clint looks up and claims to recognize Nebula, unaware that the one he was talking to was the version from 2014. As 2014 Nebula contacts Thanos, Clint realizes he was duped and attempts to fight her until she ends the transmission with her father and aims a blaster pistol on him to silence him Suddenly, Gamora and Nebula from 2023 arrive at the scene, holding 2014 Nebula at gunpoint, defending Barton, who scurries away to observe the confrontation at a distance. As Nebula attempts to urge her younger self to lay down her arms, noting the shared memory network, past Nebula cannot fathom such a future with her present-tense mindset. 2014 Gamora stands down to show good faith, and appeal to her sister, but it is all in vain as 2014 Nebula aims to shoot at her present self. In reflex, 2023 Nebula shoots her past incarnation through the cardiac region, killing her.

Battle of Earth
"This is the one? Seriously?" "The choices were him, or a tree."

- Gamora and Nebula

After rescuing Hawkeye and killing her past self, Nebula nonchalantly confirmed to and Gamora from 2014 that she fell in love with Star-Lord, the man she kneed in the groin twice after saving him from a Sakaaran soldier, in the future. Nebula then joined other heroes in an unsuccessful attempt to return the Infinity Stones to the past before Thanos could get to them. Ultimately surviving the battle, Nebula fought alongside the Guardians of the Galaxy and many of their allies. Along with Pepper Potts, 2014 Gamora, Valkyrie, Scarlet Witch, Captain Marvel, Mantis, Shuri, and Okoye, they attempt the protect the Nano Gauntlet from Thanos's forces. Through the self-sacrifice of Tony Stark, Thanos and his entire army were killed as the Avenger snapped his fingers with all six Infinity Stones attached to the Nano Gauntlet. As Pepper Potts grieved at the corpse of her deceased husband, every hero, including Nebula, bowed out of respect for Stark's sacrifice.

Team Reassembled
"You should fight one another for the honour of leadership." "Sounds fair."

- Drax the Destroyer and Nebula

Days later, they solemnly mourned the loss of Tony Stark at his lakeside cabin with Nebula and the other Guardians of the Galaxy with the exception of Gamora in attendance. She then rejoins the Guardians in the Benatar as Star-Lord reasserts his role as the leader of the team, suggesting that he and their new team member, Thor, fight for that position.

Personality
"You'd love her. Very practical, only a tiny bit sadistic."

- Tony Stark to Pepper Potts

Like Gamora, Nebula greatly despised her father, Thanos, for torturing her and turning her into a cybernetic assassin. However, despite this, she always tried, often in vain, to prove her worth to her father. Nebula lost any desire to do this after betraying Thanos, though, and has since vowed to kill her adopted father, now free to express her hatred for him. Her hatred for Thanos eclipsed any fear she had of him, as she went as far as to infiltrate the heavily guarded Sanctuary II just to try to kill Thanos, which failed miserably and she was captured and tortured badly by Thanos. This likely compounded her hatred for him even further and Nebula later immediately became furious and brutally attacked him unhesitatingly when he coldly told her he considered killing her would have been a "waste of parts". However, like Gamora, it would appear that as Thanos was the only parental figure she knew for the majority of her life, Nebula deep down did have some sentiment towards him, as she didn't look glad when Thor decapitated Thanos and even cried a bit.

Nebula had very little loyalty to a cause as she quickly betrayed Thanos once Ronan the Accuser harnessed the power of the Power Stone, believing he could kill Thanos as he declared to do so. However, when the Battle of Xandar became too intense for her liking, she quickly abandoned Ronan to escape, despite her sister's pleas for her to help the Guardians of the Galaxy, becoming an independent criminal. Nebula is also known to be highly sadistic, even being referred to as the biggest sadist in the galaxy by Taserface and she seems to take pride in her sadistic killing of her targets, with her proudly telling Gamora that "The screams of my victims can be heard through the galaxy", which Gamora replied in stride by saying that it was because Nebula often took a long time to kill her foes because she tortured them first. Unlike her sister who seeks to atone for her past crimes, even after she had redeemed herself, Nebula shows no visible signs of regret for her own crimes and she was perfectly willing to murder anyone tasked to her and anyone who stood in her own way. However, she did say that she would help the universe by killing Thanos, indicating that after her reconciliation with Gamora, she not only saw Thanos' death as vengeance but also to save other children from suffering at his hands.

Although she and Gamora grew to genuinely care for each other and develop a strong bond, ever since Thanos considered Gamora his favored children and Gamora's repeated victories over her, which caused her to be painfully cybernetically altered, Nebula had grown to resent Gamora, both for never letting her win and for being Thanos' favored daughter. However, she does still like and care for her to an extent, as Nebula said she disliked and hated her the least out of all the other children of Thanos and she did not have the heart to let her be captured by Thanos and Ronan, as she knew that either Ronan or Thanos would torture her first before killing her, causing her to genuinely believe that when she destroyed her ship and left her to die in space that she was doing Gamora a favor. However, while she ruthlessly tried to kill her sister when they fought in Ego, even dishonorably attacking Gamora despite Gamora saving her, when Nebula finally had the chance to kill her sister, she could not bring herself to do so and although she first revealed that she finally beat Gamora, Gamora's lack of care on it and admonishing her for still continuing their rivalry caused her to furiously reveal why she hated her and this caused them to warm up with each other, with Nebula finally forgiving Gamora, even joining forces with the Guardians of the Galaxy and saving her. When Nebula departed from their company, she did so on equal terms, sharing a hug with her sister before she left.

Years later, Nebula's relationship with Gamora and the Guardians appears to have improved considerably, as she trusted the Guardians enough to tell them to meet her on Titan so they can fight Thanos. Her care for Gamora was most notably shown when she furiously dueled with Thanos, she angrily asked where Gamora was. Upon realizing that Thanos had sacrificed Gamora, Nebula was visibly distraught as she implied it and seemed to show some sympathy towards Star-Lord, Gamora's boyfriend, showing more emotional sensitivity, as rather than bluntly telling him Gamora had died, she never actually openly said it and looked almost in tears when Star-Lord, in denial of Gamora's death, angrily asked Thanos to tell him that she was lying. She showed genuine care for the Guardians, looking visibly distraught as they ceased to exist. Nebula also bonds with Tony Stark as they fix a ship and leave Titan, with her using her technology to treat Tony's wounds before they infect, and Tony acknowledging in a message intended for Pepper Potts that she would like the "only slightly sadistic" cyborg. She also performed very affectionate acts for Tony, the main ones being when she wrapped a blanket around Tony and positioned him on a chair instead of on the cold floor and also offering food to Tony demonstrating how far she's come from who she once was.

Nebula's growth was most displayed when she confronted her past self, hoping to sway her to join their cause by telling her of what she becomes in the future, only resorting to lethal force when she felt that there was no other choice. She also grew to be rather sentimental, solemnly recounting to the past Gamora of how they grew as sisters in the future. She has even displayed a subtle lightheartedness and a knack for dark humor, engaging in macabre but playful banter with her comrades in the Guardians upon reuniting with them.

Powers
Luphomoid Physiology and Cybernetic Enhancements: Nebula possesses natural higher physical capabilities beyond any human being, which are further enhanced by her physiological enhancements.


 * Superhuman Strength: GotGV2 - Big Game 24.png Nebula has higher levels of superhuman strength, much greater than that of a human being. She managed to break through the windshield of an M-ship and throw its pilot out of the vehicle in mid-air with ease and managed to temporarily overpower [[Gamora]] after the two of them survived an explosion. She was also able to easily snap the neck of a Chitauri soldier with one arm, even while weakened due to prolonged torture at Thanos' hands. Nebula was even able to slightly stagger Thanos with a punch and several baton strikes, although Thanos soon easily overtook and sent her flying with a punch.
 * Superhuman Durability: Nebula can easily withstand multiple injuries, especially impact trauma, such as falls from great heights. While her body was contorted by being blasted with Drax the Destroyer's cannon at point blank range, she was otherwise unharmed and her cybernetic implants twisted her body back into place. She managed to jump onto an M-ship from several stories without withstanding injuries and survived to be inside an exploding ship before landing on her feet several stories down unharmed. When plugging her mechanical arm into the ship to power the ship's energy beams, she was electrocuted and experienced great pain, but otherwise survived. She even managed to survive a powerful blow from Thanos and later a shockwave from the Infinity Gauntlet.
 * Superhuman Agility: Nebula has agility and coordination greater than that of a human being, allowing her to easily keep up with Gamora in a fight and dodge her sister's attacks.
 * Regenerative Healing Factor:Nebula-Broken-Jaw.png Nebula's extensive cybernetic implants allow her to quickly heal from otherwise near-fatal injuries, such as when her body was crushed and mangled when withstanding a direct blow from Drax's cannon. Due to her implants, she was able to reshape her body back to its original form by snapping her arms and jaw back into their normal place. Nebula was able to reshape her body after the impact of an exploding M-ship.
 * Light Emission: Due to her extensive cybernetic visual prosthesis, Nebula is able to emit vast amounts of light energy from her eyes. This enables her to see within places of low light.
 * Image Projection: Nebula's built-in synaptic drive and bionic visual enhancements give her the capability of replaying past memories in the form of light projections. This was shown when Thanos accessed the memory file of 2023 Nebula through her past self, as the two were mentally linked.
 * Concussive Energy Blast Generation: Nebula’s cybernetic arm allows her to fire concussive electroshock charges from her hand towards her enemies or over a specific target area.
 * Electronic Hacking: Nebula's cybernetic hand is able to be internal connected into any computer system or digital device so she is able to hack and access many electronics. This was shown as she was able to connect her cybernetics with the computer system linked with the Quantum Tunnel to transport 2014 Thanos and his army to the present.

Abilities
"I am every inch the warrior you are. The screams of my victims fill every field."

- Nebula to Gamora


 * Master Assassin: Ever since she was a child, Nebula has trained extensively as an assassin under Thanos. She trained with Gamora throughout her childhood, but Nebula stated that she was not as skilled as her sister. Despite that, Nebula was skilled enough that even Thanos commented Nebula almost succeeded in killing him after sneaking into his spaceship.
 * Expert Combatant: As a highly trained assassin of Thanos, Nebula is accomplished in armed and unarmed combat. Nebula's skill in combat allowed her to compete with "the deadliest woman in the galaxy," Gamora, for a prolonged amount of time and even managed to defeat her when both were wounded after escaping an explosion, although it should be noted that Gamora was weakened more than Nebula was due to Nebula's more extensive cybernetics and the fact that Gamora had not been fighting to kill, but was trying to reason with Nebula; thus, she was holding back. Her most impressive display of skill was seen when she briefly fought Thanos one-on-one; although she was eventually no match for her far stronger and more experienced father, Nebula was still able to fare better than Drax the Destroyer as well as Doctor Strange, able to briefly pressure and land two blows on Thanos, whereas Drax and Strange had difficulty fighting Thanos even with a webbed cotton hampering Thanos' eyesight and could not a land single hit in said occasion, although Thanos was briefly distracted by her mentions of Gamora and soon easily knocked her aside.
 * Staff Mastery: Nebula is highly skilled in using sticks and staffs, her retractable electric batons being her preferred weapon. Using her staff, she was able to contend with Gamora using her sword and even managed to disarm her. Later, she was able to briefly force Thanos to the defensive and land some blows until she was defeated easily.
 * Expert Pilot: Nebula is a highly trained pilot, with Gamora acknowledging her as being better and more knowledgeable at piloting than her, capable of easily flying a Necrocraft and an M-ship with great efficiency. During the Skirmish on Knowhere, Nebula was able to maneuver around Gamora's mining pod with ease and eventually shoot her ship down.
 * Expert Marksman: Nebula is proficient in sharpshooting. During the Attack on Berhert, Nebula was able to accurately shoot off Yondu Udonta's Yaka Arrow Controller before incapacitating Rocket Raccoon.
 * Gifted Intellect: Due to her synaptic drive, Nebula possesses the ability to quickly process vast amounts of information. Nebula also possesses vast knowledge on how time travel works, displayed by her notes on how changing the past does not affect one's future.

Equipment

 * 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 materialize around the wearer's regular clothes, managing to be summoned when time travel is required again, and disappear 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.

Cybernetic Enhancements
In her early years under Thanos' wing, Nebula received various upgrades that allowed her to gain extensive cybernetic properties and body features.
 * Cybernetic Arm: Nebula possesses a cybernetic metal arm after her escape from a Laser Thorn Energy Net within the Cloud Tombs of Praxius. Nebula's arm contains many internal components such as a and contact whiplash which serves as a grappling hook that she used when infiltrating Praxius IX. The arm is also capable of acting as a generator for electricity as it was used to power the broken down Ravagers ship her and Yondu Udonta were on to eliminate the multiple Sovereign ships. Her hand is designed to imitate the appearance of flesh, but it is capable of hacking into computer systems, demonstrated by a time traveled version of Nebula from 2014. However, after losing her left hand during the Battle of Xandar, Nebula replaces it with another cybernetic hand which does not imitate the appearance of flesh. In order to obtain the Orb, Nebula had to damage her arm in order to pull it out of the energy barrier encasing it.
 * Tempersteel Claws: Nebula possesses two sets of retractable claws, one in each hand, that she can activate to grip onto surfaces to assist her when she is climbing.
 * Regeneration Implant: Nebula possesses a regeneration implant that is situated within her body. This implant allows her to rapidly heal from near-fatal injuries and wounds as well as enabling her to reshape her body back to its original form.
 * Cybernetic Communicator: Nebula has a cybernetic message communicator planted in her brain, which she used to alert the Sakaarans that Gamora had the Orb, and to directly confront her shortly thereafter. Nebula also used to it to alert Thanos that she was in possession of the Nano Gauntlet during the Attack on the New Avengers Facility.
 * Visual Prosthesis: During Nebula's upbringing with Thanos, her father had pulled her eye from her head as a consequence for losing a battle against Gamora. Thanos replaced her left eye with a bionic one, this bionic eye allows her to create projections of a specific event.
 * Synaptic Drive: One of Nebula’s cybernetics includes a neuro-synaptic implant located on the side of her head and also forms part of her brain. It is capable of recording memories and replaying memory files from past events. A glitch can occur if Synaptic Drives from different timelines are located in the same time, malfunctioning and granting the drives access to the records of the other.

Weapons

 * Electroshock Batons: Nebula-Fight-Gamora.png]] Nebula's weapon of choice are baton-like electroshock weapons which can be combined to form a longer electroshock staff that can generate powerful amounts of electrical energy. It could also be thrown and return magnetically to her cybernetic arm, demonstrated by her brief skirmish with Thanos.
 * Electric Blaster: Nebula’s alternate weapon is a blaster which can fire blasts of electricity to electrocute and stun its targets, knocking them unconscious. She used it on Rocket Raccoon and Yondu Udonta to escape Berhert.
 * Godslayer: During their skirmish on Ego the Living Planet, Nebula took Gamora's sword Godslayer and attempted to kill her sister with it. However, she chose not to.
 * Nebula's Energy Dagger: During the Kidnapping of Nebula, 2014 Nebula possessed a dagger that was able to release blue light energy and used it to remove the orange headpiece from the face of her future self.

Vehicles

 * Dark Aster: During her time working with Ronan the Accuser, Nebula was a passenger on his ship. She and everyone else on the ship used it for transportation during Ronan's campaign for vengeance. She later abandoned the ship during the Battle of Xandar.
 * M-ship: After being defeated in combat by Gamora during the Battle of Xandar, Nebula was left hanging hundreds of feet above Xandar's surface, with her hand trapped onto a spike on the outside of the Dark Aster. Gamora tried to reason with Nebula but Nebula refused and cut off her cybernetic hand. Instead of falling from the sky to her death, she landed on top of a Ravager's M-ship. Nebula then threw the pilot out and took control of the ship before flying it far away from the battle. She would later use another M-ship to fly to Ego to try to kill Gamora, she crashed the ship during her fight with Gamora.
 * Milano: Nebula was held prisoner on the Milano after being captured by the Guardians of the Galaxy before it crashed on Berhert.
 * Sanctuary II: Nebula snuck aboard this ship to kill Thanos. She nearly succeeded, but failed and was captured. When Thanos captured Gamora, he brought her to Nebula to force her to reveal the location of the Soul Stone. Thanos started to torture Nebula and Gamora told Thanos where he could find the stone to stop her sister's suffering. After Thanos and Gamora left, Nebula escaped after killing a Chitauri henchman and stealing a Necrocraft.
 * Necrocraft: After escaping captivity on the Sanctuary II, Nebula stole a Necrocraft and used it to go to Titan and crashed the ship onto Thanos in an attempt to kill him, interrupting his battle with the Avengers and Guardians, although Thanos was uninjured.
 * Benatar: Following the battle of Titan, Nebula and Iron Man fixed Star-Lord's ship and left the planet. It would break down after 24 days of travel, but eventually, they were rescued in deep space by Captain Marvel, who delivered them to Earth. Nebula would also ride the Benatar to take part in the Ambush on Thanos.

Trivia

 * In the comics, Nebula is a space pirate and mercenary who claims to be Thanos' granddaughter. Her appearance in the movies seems to be based more on her second incarnation from the comics.

Behind the Scenes

 * revealed she was up for the role of Nebula.
 * In Guardians of the Galaxy, Karen Gillan shaved her head to play Nebula (the hair, in turn, was made into a wig, which Gillan wore in the TV show Selfie). In later appearances, her hair was only shortened, with the reminder lifted into a bun which was hidden by the prosthetics that make Nebula's facial make-up.
 * Nebula's make-up, which includes a glued together five-piece prosthetic in the head and contact lenses, took approximately four hours and 15 minutes to apply and another 30 minutes to remove in Guardians of the Galaxy. By Guardians of the Galaxy Vol. 2, the applying was reduced to a two and a half hours.
 * Karen Gillan stated that "I think she's a really interesting character. What I like to play around with is how jealous she is. She's Gamora's sister, and there's a lot of sibling rivalry. That's the most interesting aspect to me because jealousy can consume you and turn you bitter, and ugly. And she's a total sadist, so that's fun too."
 * Karen Gillan also said, "She is very sadistic and evil, but I like to think for a very valid reason."
 * The 2014 self of Nebula was originally going to die during the Battle of Earth sequence in Avengers: Endgame upon trying to use the Infinity Gauntlet to please Thanos, but the idea was scrapped.
 * Monique Ganderton, Olivia Jackson, Kelly Richardson, Amy Lynn Tuttle, Shauna Galligan, Joanna Bennett and Jess Durham were stunt doubles for Karen Gillan in the role of Nebula.
 * Collette Von Tora, Caileigh Scott and Tracie Garrison were stand-ins for Karen Gillan in the role of Nebula.
