Winter Soldier

"What you did all these years ... it wasn't you. You didn't have a choice." "I know. But I did it."

- Steve Rogers and Bucky Barnes

Sergeant James Buchanan "Bucky" Barnes is a former soldier of the 107th Infantry Regiment and the childhood best friend of Steve Rogers. As World War II was escalating, he was recruited to become a member of the Howling Commandos. During the time between 1943 and the end of the war in 1945, the Howling Commandos had attacked and disabled many HYDRA bases.

In 1945, in an attempt to capture HYDRA scientist Arnim Zola, Barnes was attacked and promptly plummeted off the side of a HYDRA train. He was then presumed to be deceased, though unbeknownst to his teammates Barnes had actually survived, due to the experiments performed on him by Zola while he was briefly captured as a POW, albeit with the loss of his left arm. Brainwashed and armed with a new cybernetic limb, Barnes ultimately became an enhanced HYDRA operative known as the Winter Soldier. Over the next several decades, he would eliminate anyone who posed a threat to HYDRA, including his former ally, Howard Stark. Between missions, Barnes would be put into a cryogenic stasis to preserve his longevity. Over half a century later, when he was ordered by HYDRA leader Alexander Pierce to assassinate S.H.I.E.L.D. Director Nick Fury, the Winter Soldier was confronted by his old friend, Steve Rogers, triggering him to begin remembering his prior life.

In the aftermath of the Battle at the Triskelion, the Winter Soldier went on the run from HYDRA on a self-imposed mission to remember his past and end his violent history. However, during this time Barnes was accused of being the perpetrator behind the Bombing of the Vienna International Centre, which claimed the lives of many individuals including T'Chaka, the king of Wakanda, which led to T'Chaka's son T'Challa to pursue him to gain vengeance. Barnes was saved by Captain America, sparking the Avengers Civil War as he also became a target for Secretary of State Thaddeus Ross and Iron Man. When Iron Man learned that the Winter Soldier had killed his family, Barnes was once again saved by Rogers as it was revealed that Helmut Zemo had organized the entire civil war between the Avengers as revenge for incidentally killing his family a year prior during the Battle of Sokovia. Barnes was then taken to Wakanda, where he chose to be cryogenically frozen until his mind could be cured of the mental programming implanted by HYDRA.

Meeting Steve Rogers
"Thank you Buck, but I can get by on my own." "The thing is, you don't have to. I'm with you to the end of the line, pal."

- Steve Rogers and Bucky Barnes after Sarah Rogers' funeral

James Buchanan Barnes was born on March 10, 1917 as the eldest child of four. Barnes grew up to be an overachiever, having been an excellent athlete who also excelled in the classroom. Sometime during his childhood, he met Steve Rogers when bullies were trying to steal his money. . The two became best friends and stuck together for many years. In 1936, Steve's mother, Sarah Rogers, died of tuberculosis. After her funeral, Barnes walked Rogers home and offered him his place to stay, but Rogers refused, saying he could get by on his own. Seeing Rogers struggling to find his house keys, Barnes revealed his secret key and told him that he did not have to because he was with him "to the end of the line," something Rogers would keep to heart for a long time.

Training Rogers
A year later, during an art class, Barnes and Rogers found out that America had joined the Second World War. By this time, Barnes was a three-time YMCA welterweight boxing champion. He then spent two weeks training Rogers at Goldie's Boxing Gym. They visited the US Recruiting and Induction Center in New York City where Rogers was classified as 4F and rejected from service. Barnes was later drafted in the Army.

Sergeant Barnes
"They'll catch you and worse they'll actually take you." "Look I know you don't think I can do this..." "This isn't a back alley, Steve. It's war! Why are you so keen to fight? There are so many important jobs."

- Bucky Barnes to Steve Rogers

Barnes, along with the rest of the 107th Infantry Regiment, was trained during the winter at Camp McCoy, Wisconsin. Eventually, Barnes rose to the rank of Sergeant. The day before his shipment out to England, Barnes found Steve Rogers getting beaten up by a bully. He came to the defence of his friend and quickly sent the bully running away with a punch to the jaw and a kick to the behind. Barnes learned that Rogers had been attempting to enlist in the army again so he could fight in World War II, using false documents to try and get deployed. Barnes informed Rogers that he had received his orders and would be going to war the next morning. At first, Rogers seemed upset, as he was not shipping out to war as well. Barnes remained determined to cheer his friend up and reminded him that he would last be the last eligible bachelor left in New York City. Barnes and Rogers then went to the Stark Expo together, with Barnes determined to enjoy his last day in the city before shipping out. What Barnes did not tell Rogers, however, was that it was in fact a double date with Connie and Bonnie, who were both highly excited to spend the evening with a handsome soldier like Sgt Barnes. When Rogers asked what Barnes had told his own date about him, Barnes simply replied, "only the good stuff" while greeting the girls. While happily exploring the Expo together, the group of four saw the inventions which Stark Industries was showing off, such as Phineas Horton's Synthetic Man. They later watched as Howard Stark himself demonstrated his prototype flying car, which had greatly impressed Barnes, until it malfunctioned and fell to the ground hard, although Stark was still able to joke that the car was only a prototype. When Barnes turned around to suggest the group go dancing, he saw that Rogers had walked away from the group to try and enlist in the army yet again, despite Barnes' many previous objections. Barnes soon found Rogers trying to enlist, and first tried to persuade him to rejoin him on the double date. When that did not work, he reminded him that he wasn't going to be fighting in a back alley, but in a war. Despite Barnes' protests, Rogers went through with it, but said a heartfelt goodbye to Barnes before doing so. Rogers told him not to win the war until he got there, and Barnes left with the girls. Barnes and his unit, the 107th shipped out to England the next day.

Prisoner of War
"I thought you were dead." "I thought you were smaller."

- Captain America and Bucky Barnes

On the frontlines, Barnes and his unit, including Dum Dum Dugan and Gabe Jones, were ambushed by the Nazis at Azzano. Though the battle seemed hopeless as they were strongly outgunned with no reinforcements, the battle turned when another German unit appeared and used an extremely powerful tank to kill the Nazis. The tank then turned to Barnes' unit and they were soon captured by HYDRA. They were sent to work at the HYDRA weapons facility in the Austrian Alps, halfway between and. In October 1943, Barnes met other Allied POWs: including Jacques Dernier and James Montgomery Falsworth. During his imprisonment in the facility, he was viciously beaten by Colonel Lohmer. However, other prisoners organized an "accident" which resulted in Lohmer's death. Barnes and his friends worked on parts of the Valkyrie, a giant super bomber. When Barnes became too weak to continue, he was taken to undergo experiments conducted by Arnim Zola. In November 1943, the facility was infiltrated by Steve Rogers, who had undergone an experiment giving him enhanced strength. Rogers made his way through the base and freed the prisoners, including Barnes, having discovered him while chasing down Zola. Seeing his friend and his newly transformed body, Barnes was highly surprised and confused, noting that he remembered Rogers being considerably shorter than he was now while Rogers dragged him out.

As the freed POW's battled against the HYDRA forces, being led by Dum Dum Dugan, Rogers and Barnes became trapped inside the base as it began to self destruct. During the escape, Barnes and Rogers encountered Johann Schmidt and Arnim Zola, who mocked Rogers' transformation at the hands of Abraham Erskine. After a brief fight, Schmidt and Rogers soon became separated before Schmidt revealed to them his true demonic face, caused by taking an early version of the Super Soldier Serum. Schmidt mocked Rogers' belief that he was still a simple soldier despite being a higher class of humanity before escaping from the base. With Schmidt gone, Rogers and Barnes refocused their efforts and began working out an escape route. Rogers suggested that they move up and they decided to use a support beam to move to a safe section of the facility. Due to his poor health, Rogers insisted that Barnes get himself to safety first, however just as he reached the other side, the beam fell apart from under Barnes' feet, trapping Rogers on the other side of the exploding facility. Although Rogers ordered that Barnes escape now before the base exploded and killed them both, Barnes refused, insisting that he would not leave his friend behind; he claimed that they would be able to find another way across. Barnes watched in amazement as Rogers used his strength to bend a steel bar out of his way before launching himself across the gap and rejoining Barnes. They were then able to escape moments before the entire facility was destroyed. Barnes and Rogers regrouped with the rest of the escaped POWs and together they walked with the other freed soldiers all the way back to Colonel Chester Phillips' base in Italy, 30 miles out. Once they arrived along with the weapons and vehicles they had stolen from HYDRA, they were greeted warmly by the other soldiers and Phillips chose not to punish Rogers for undertaking the rescue mission against Phillip's strict orders. As the entire unit gathered together, Barnes called for all the soldiers to cheer for their savior Captain America. The POWs were then given medical attention before being given some time away from the battlefield to recover.

Recruited into the Team
"You ready to follow Captain America into the jaws of death?" "Hell, no. That little guy from Brooklyn who was too dumb to run away from a fight, I'm following him."

- Steve Rogers and Bucky Barnes

After their escape from the HYDRA prison, Barnes, Dum Dum Dugan, Jacques Dernier, Gabe Jones, Jim Morita, and James Montgomery Falsworth were given a break from duty. Steve Rogers later joined them in a pub and convinced them to join his crusade against the Nazis and HYDRA, forming a group of fighters known as the Howling Commandos. Barnes told Rogers that he would not follow Captain America, but he would follow his friend. When Peggy Carter also arrived at the pub to inform Rogers of an upcoming meeting with Chester Phillips and Howard Stark, Barnes had to deal with the realization that Rogers was now the one who gets flirted with, not him. Rogers teased his friend by suggested that she might have a friend before discussing if Rogers would be keeping the uniform of Captain America. Eventually, Barnes and the newly formed Howling Commandos joined Captain America on the battlefield. Over the following months the Commandos progressively destroyed most major HYDRA operations, preventing Johann Schmidt and Arnim Zola any real ability to work on their scientific projects and plans, all while destroying HYDRA's army units, tanks and facilities. Barnes would often work as the sniper of the group, protecting his team of the Commandos.

Final Mission
"I had him on the ropes." "I know you did."

- Bucky Barnes and Steve Rogers

At the beginning of 1945, Barnes, Captain America and the rest of the Howling Commandos prepared for a mission to board a HYDRA train carrying Arnim Zola, with the aim of capturing the HYDRA scientist to learn about the plans of the Red Skull. While they looked over the side of the snowy mountain they would have to manurer around, Barnes joked that this mission was Rogers' way of getting payback for the time Barnes made Rogers ride a roller coaster that made him throw up, which Rogers neither confirmed nor denied. When Jim Morita intercepted a radio signal from HYDRA confirming that Zola was on the train, Barnes, Rogers and Gabe Jones used a zip wire to board the train as it traveled through the mountains. While Jones stayed on top of the roof of the train, Barnes and Steve Rogers entered and began exploring the various carriages. Moments after their arrival however, they were suddenly split up and ambushed by a team of armoured HYDRA soldiers sent to kill them by Zola. While Rogers was forced to fight a heavily armed HYDRA guard, Barnes became pinned down by three soldiers. Although he was able to kill two, he quickly ran out of ammunition and feared he would soon be killed. Rogers, however, was able to open the door and throw him a new gun which he used to shoot and kill the last remaining soldier when Rogers distracted him. Barnes claimed that he had him on the ropes and Rogers assured him that he believed him. However just as the pair began to relax, another HYDRA soldier then appeared behind them and fired at them with a HYDRA Assault Rifle, blowing a hole through the side of the train and knocking Rogers off his feet. Barnes picked up Captain America's Shield and fired at the soldier, but he was shot again, the power of the blast throwing him off the train and leaving him hanging on to a damaged rail for dear life as the train continued to speed through the mountains. Rogers dispatched the soldier by launching his shield at him and turned his attention to desperately trying to rescue Barnes as he hung off a rail on the side of the train. Rogers begged Barnes to hold on as he inched closer to him and tried to grab his hand, but before they could reach each other the rail snapped, which resulted in Barnes falling into an icy river below while Rogers could only look on in horror as his closest friend seemingly disappeared forever.

Found by HYDRA
"Sergeant Barnes... the procedure has already started. You are to be the new fist of HYDRA!"

- Arnim Zola to Bucky Barnes

Due to his enhanced physiology produced by HYDRA's experiments, Barnes was just able to survive the fall from Arnim Zola's train, though his left arm was ripped from his body upon impact. His nearly lifeless body was discovered by a Soviet soldier, and was handed over to HYDRA. He was kept their prisoner for many years, until Arnim Zola was released from the SSR's custody, wishing to continue his experiments. In the care of the new HYDRA, working within S.H.I.E.L.D., Barnes underwent further experimentation at the hands of Zola, as the first subject of the Winter Soldier Program. Removing the remnants of his severed arm, the doctors replaced the missing limb with a prosthetic one. Barnes underwent mind control methods to keep him under their command. Over time, Barnes would lose all memory of his former life and became nothing more than a weapon. With his body at the peak of physical perfection and his arm at the highest level of weaponized technology, HYDRA put Barnes to use as their personal weapon for many years. They had him frozen in suspended animation to prevent him from ageing after every mission. Whenever Barnes completed a mission, HYDRA would have his mind wiped to ensure he remained memory-free and emotionless towards those he killed.

HYDRA's Operative
"Most of the intelligence community doesn't believe he exists. The ones that do call him the Winter Soldier. He's a ghost. You'll never find him."

- Black Widow to Captain America

Receiving vast training from HYDRA, Barnes became a formidable fighter and an even more ruthless killer. His experiences with the KGB would earn him the name of the "Winter Soldier". The Winter Soldier would remain frozen for long periods of time until HYDRA saw fit to unfreeze him for missions. Over the next 50 years, the Winter Soldier was responsible for numerous assassinations, killing various sorts of targets, from scientific minds to political figures, including U.S President in 1963. Due to his expertise on the field and the shadowy nature of his existence, the Winter Soldier became something of a ghost story, with intelligence agencies doubting he even existed.

Assassination of Howard and Maria Stark
"Longing, Rusted, Seventeen, Daybreak, Furnace, Nine, Benign, Homecoming, One, Freight Car. Good morning, Soldier." "Ready to comply."

- Vasily Karpov and Winter Soldier

While being kept on ice in a Cryostasis Chamber, Winter Soldier was held in the HYDRA Siberian Facility alongside other Winter Soldiers. Eventually he was defrosted by Vasily Karpov who, once his memories had been wiped yet again by the Memory Suppressing Machine, ensured Barnes was loyal to HYDRA by using key words to activate his training. With his mind clear of his past life, the Winter Soldier once again became just an empty shell of a man simply awaiting his mission orders. Karpov informed Barnes that they needed him to steal a supply of the Super Soldier Serum from the car of Howard Stark, assassinating Stark in the process. As Barnes had no memories left of his time serving in World War II alongside Stark, he agreed to take on the mission without any hesitation. Taking on the mission, Winter Soldier waited for Stark to leave his home and travel down the road; at which point he gave chase on his motorbike and fired into the car, causing it to veer off the road and crash into a nearby tree. Momentarily ignoring the injured victims, Winter Soldier first ensured that the Super Soldier Serum was safe before turning his attention to Stark, who had survived and slowly crawled away from the car to attempt to escape. As Stark begged for his attacker to help save his wife's life, the Winter Soldier ignored the pleas and took ahold of Stark with his robotic arm. As Stark looked up at his assassin, he recognized him from their time together during World War II, as well as working with their mutual friend, Captain America. Confused, Stark addressed him by his real name of Barnes. However, the Winter Soldier ignored the comments and proceeded to beat Stark to death before placing him back in the car and strangling his wife. He then ensured the crash looked like an accident and destroyed the various CCTV cameras.

Training other Winter Soldiers
"I'm not the only Winter Soldier." "Who were they?" "The most elite death squad."

- Winter Soldier and Captain America

As HYDRA's enemies continued to grow on, it was decided that more enhanced Winter Soldier assassins were needed, so volunteers were injected with the Super Soldier Serum that the Winter Soldier had stolen from Howard Stark and used in the Winter Soldier Program. To ensure the soldiers were battle ready, the Winter Soldier was tasked with training them; if they were able to overpower and subdue him, then they would be accepted into the program. During one of these training sessions at the HYDRA Siberian Facility, the Winter Soldier was eventually beaten and, as a result, Vasily Karpov came in to congratulate the victor while a doctor went to check on his vitals. However, the Soldier was fuelled by adrenaline and attacked the doctor, slamming his face hard into the ground and killing him. As a result a riot began with the other Winter Soldiers rising up against their captors and attacking Karpov. As a fight broke out, the Winter Soldier was ordered by the terrified Karpov to protect him and managed to get him away from the danger, closing the door of the door behind him to lock the Soldiers inside. While the HYDRA guards eventually subdued the other soldiers, despite several being beaten to death, before putting them back into Cryostasis Chambers. It was then decided by Karpov that they should be kept on ice until they could be controlled completely.

First Encounter with the Black Widow
"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. A Soviet slug, no rifling."

- Black Widow to Steve Rogers about the Winter Soldier

In 2009, the Winter Soldier was sent to kill a nuclear scientist. He found his target being escorted by S.H.I.E.L.D. Agent Natasha Romanoff. Without hesitation, he attacked his target, sending the car containing the scientist and Romanoff over a cliff. Finding that Romanoff had saved the target from falling to his death, the Winter Soldier fired a single round through Romanoff's stomach. The bullet struck the scientist, effectively killing him. He then made his getaway without pursuit.

Bucky's Legacy
"Best friends since childhood, Bucky Barnes and Steven Rogers were inseparable on both schoolyard and battlefield. Barnes is the only Howling Commando to give his life in service of his country."

- Smithsonian Institution

Almost seventy years after the end of World War II, Steve Rogers, awakened in the 21st century, studied S.H.I.E.L.D.'s files about the Commandos. In Bucky's file, he was reported as "Missing In Action", as his corpse was never found. Therefore, he was never officially classified as deceased. In the Smithsonian Institution, a part of the Captain America Exhibit is dedicated to Bucky's memory and shows a short biography of his life. Before 2014, Barnes' name was listed on the Wall of Valor of the S.H.I.E.L.D. Academy of Science and Technology.

Attack on Nick Fury
"He's fast. Strong. Had a metal arm."

- Captain America

In 2014, the Winter Soldier was activated to assassinate the S.H.I.E.L.D. Director Nick Fury after he began to unravel HYDRA's secret existence due to questioning Project Insight. When Fury managed to escape death at the hands of over a dozen HYDRA agents in Washington, D.C., the Winter Soldier managed to get ahead of Fury's car and disabled it using a Magnetic Disk Grenade, which caused the car to flip as the Winter Soldier moved aside just in time. However, when the Winter Soldier made his way to the vehicle to finish Fury, he found his target had used a Mouse Hole to escape from his wrecked car and into the sewers to escape his would be assassins. Unwilling to allow his target to get away alive, the Winter Soldier later located Fury at Steve Rogers' apartment, where he was attempting to give Rogers vital information about his attack and the possible infiltration within S.H.I.E.L.D.. Before Fury could reveal his information, the Winter Soldier shot him through the back multiple times, puncturing straight through his Bulletproof Vest, through the wall from another building across the street. With Fury seemingly dead, the Winter Soldier made his escape, but Rogers gave chase and attempted to subdue Barnes by throwing his shield at him. However, Barnes stopped running and simply caught the shield with his bionic arm, throwing it back with incredible force after looking at Rogers for a moment. As Rogers stood frozen in shock at the assassin's strength and reflexes, Barnes leaped off the roof and escaped before Rogers could see where he went.

Hunting Captain America
"The timetable has moved. Our window is limited. Two targets, level six. They already cost me Zola. I want confirmed death of them in ten hours."

- Alexander Pierce to the Winter Soldier

Instead of being returned to cryo-sleep, the Winter Soldier was later sent to Alexander Pierce's house for his next orders. He was informed that his next targets were Steve Rogers and Natasha Romanoff, who were attempting to reveal HYDRA's Project Insight plan which involved wiping out over a million targets using S.H.I.E.L.D.'s Helicarriers.

Battle of Washington, D.C.
"У меня есть ее. Найти его."

- Winter Soldier to his HYDRA team

The next day he attacked Rogers, Romanoff, and Sam Wilson on the freeway while they were kidnapping HYDRA sleeper agent, Jasper Sitwell. Throwing Sitwell from the car into the path of an incoming truck, the Winter Soldier destroyed the car and forced it off the road. When he fired a grenade at his targets, Rogers took the blow and went flying off the bridge into a bus below. With his targets off the bridge and seemingly taken out of the fight, the Soldier took a machine gun and aimed off the bridge to finish him off. However, he was shot in the eye by Black Widow, surviving due to his protective mask. Instead of engaging Romanoff, the Soldier pursued her through the streets of Washington, D.C., as the civilians ran for cover. Barnes soon believed he had Romanoff cornered when he heard her voice from behind a parked car. In an attempt to kill his target, the Winter Soldier dropped a grenade but soon discovered it was a trick and was ambushed as Black Widow jumped onto his shoulder and attempted to strangle him. The Winter Soldier managed to throw her off onto a nearby car before having his prosthetic arm temporarily disabled by one of Romanoff's Taser Disks. After shooting Romanoff through the shoulder, the Winter Soldier was attacked by Rogers before he could assassinate her. The two engaged in a brutal one-on-one fight, both rivaling each other with every move. Determined to kill his target, the Winter Soldier fired every round in his gun at Captain America, only for them to be blocked by the shield. Barnes resorted to using his knife, attempting to plunge it into Rogers' throat, but was soon disarmed. Barnes briefly got a hold of Rogers' shield and attempted to throw it at Rogers with force, but it missed Rogers and cut through a nearby van. The pair were forced to resort to hand to hand combat, and in the midst of the fight, Rogers ripped the Winter Soldier's mask off and stared in disbelief as Barnes turned and revealed his face. Recognizing him as Bucky Barnes, Rogers brought the Winter Soldier to a stand still. The Soldier briefly questioned who Barnes was, but soon remembered his mission and swiftly raised his gun to take a shot. The Winter Soldier was suddenly knocked to the ground by Falcon. He attempted to shoot again, but was then shot at by Natasha Romanoff with the grenade launcher he dropped while fighting Rogers. He dodged the grenade and was forced to flee while HYDRA agents captured Rogers, Romanoff, and Wilson.

Forgotten Memories
"The man on the bridge, who was he?" "You met him earlier this week on another assignment." "I knew him."

- Bucky Barnes and Alexander Pierce

Regrouping with HYDRA, Barnes was taken back to the Ideal Federal Savings Bank, where he became erratic and violent towards the doctors. After they repaired his arm, he began to remember fragments from his past. These fragments included his fall from the train, as well as the operations performed on him by Arnim Zola which threw him into a rage. Alexander Pierce arrived at the Base to obtain Barnes' mission report, only to find Barnes unresponsive and refusing to speak until Pierce hit him across the face. Barnes claimed that he knew Steve Rogers somehow. Pierce claimed that he only remembered him because he had met him a few days ago on the assignment to kill Nick Fury, but Barnes insisted that he knew him. Pierce ordered Barnes to undergo further mind alterations to force his cooperation.

Battle at the Triskelion
"People are gonna die, Buck. I can't let that happen... Please don't make me do this."

- Captain America to Barnes at the beginning of their showdown

Before HYDRA could complete their goal and activate the Helicarriers, Captain America and his allies infiltrated the Triskelion and revealed HYDRA's presence to his fellow agents who actively engaged in battle with HYDRA's undercover agents. In the ensuing chaos, Barnes began murdering pilots and destroying Quinjets. He flew a Quinjet to a Helicarrier, where he ambushed Rogers and Falcon. He shoved Rogers off the Helicarrier, destroyed Wilson's flight suit and kicked him off the Helicarrier. Seeing that Rogers did not die and was still on the Helicarrier, the Winter Soldier ran ahead to meet him at the Target System for a final showdown. The Winter Soldier went to confront Captain America himself before he could reboot the Helicarrier's Target System. As the two stood opposite one another, Rogers pleaded with his former best friend for him to remember him and think of the amount of people who were going to die. Barnes remained silent and ignored these pleas. Seeing no other choice, Rogers engaged Barnes in combat once again. The two fought in a lengthy violent hand-to-hand fight, during which the Winter Soldier got possession of the Targeting Chip. Desperately trying to obtain the chip, Rogers broke Barnes' arm, disabled the robotic one and injured his leg before subduing him. The Winter Soldier, however, regained consciousness before Rogers could reach the System Override, shooting him multiple times. Despite this, Rogers managed to swap the Data Chips and had S.H.I.E.L.D. Agent Maria Hill reset the three Helicarriers to target each other and open fire, even with himself still aboard one. As the Helicarrier began to fall apart in mid-air, the Winter Soldier became trapped under debris. Rogers leaped to his friend's aid and freed him. The Winter Soldier instantly betrayed Rogers and attacked again. Begging for Barnes to remember him, Rogers reminded him of his name and past. Rogers allowed his shield drop out of the carrier, refusing to fight. Barnes refused to listen, violently beating Rogers with his bionic arm as their surroundings began to deteriorate.

Regaining Memories
"I'm not gonna fight you. You're my friend." "You're my mission. You're... my... mission!" "Then finish it. 'Cause I'm with you to the end of the line."

- Captain America and Winter Soldier

As the Winter Soldier ignored Captain America's words and insisted he was only his mission, Steve quoted something Barnes said to him more than 70 years ago after his mother's funeral. As Barnes began to remember, he relented, unwilling to throw another punch. The surface beneath them fell away, and Rogers plummeted into the river below. Barnes quickly grabbed on to a metal beam, which allowed him to stay on the Helicarrier. Realizing that Rogers truly was his friend, Barnes let go of the beam and dove into the water after Rogers and pulled him ashore, saving his old friend's life. After saving him, Barnes quickly checked to see if Rogers was still breathing. After he discovered he was, he slowly walked off into the nearby woods, going on a mission to discover his true identity. Having escaped the Triskelion wreckage, Barnes returned to Ideal Federal Savings Bank, where he encountered the HYDRA scientists. Free from the mind control, Barnes assaulted them; however, this reminded Barnes of the people he murdered, preventing him from killing them. Barnes later went to the Smithsonian Institution where he found a memorial for the late Howling Commando James Barnes, who had seemingly been killed during World War II.

Found by Captain America
"I wasn't in Vienna, I don't do that anymore." "Well the people that think you did are coming here now, and they're not planning on taking you alive." "That's smart... Good strategy."

- Bucky Barnes and Steve Rogers

Free from HYDRA, Barnes was on the run from the government. He traveled to an old Romanian safe-house to investigate his past; the more he learnt of his past life in the Howling Commandos, the more he added into a notebook of all his memories. While walking through Romanian capital Bucharest and buying plums from a street seller, Barnes caught sight of a nervous man staring at him. Fearing that his identity might be at risk of being learned, Barnes walked over to the man who ran as fast as he could away from him. Taking one of the newspapers the man was selling, Barnes then discovered that he was being accused of the Bombing of the Vienna International Centre in Austria, which had claimed the lives of several people, including King T'Chaka of Wakanda. Seeing this, Barnes decided to collect his belongings and flee. Returning to his hideout, Barnes discovered Captain America was already there. When Rogers asked if Barnes knew who he was, Barnes claimed that he had learnt of him in a museum although Rogers knew he was lying. Barnes insisted that he was not responsible for the terrorist attacks as that was not who he was anymore, but Rogers noted that the people who did blame him were coming to their location now intending to kill him. Their re-union would eventually be interrupted by the arrival of the Joint Counter Terrorist Centre who charged into the building from the rooftop and the hallway. Working together, Barnes and Rogers deflected a grenade thrown inside by covering it with Captain America's Shield. Barnes took his backpack and threw it out of the window where it landed on the next building's roof, reassuring Rogers that he did not plan on killing anybody. As more agents charged into the room, Barnes used his Prosthetic Arm to block the gunshots before using any weapons were nearby to subdue his attackers, including a concrete block. Moving into the stairway where a large unit of Joint Counter Terrorist Centre agents were moving to him, Barnes continued to fight back against his would be killers, while Rogers followed behind, ensuring nobody was accidentally killed due to Barnes' less careful fighting style. Leaving Rogers behind, Barnes jumped down several stories, using his Prosthetic Arm to catch himself before running to a balcony and leaping onto the next building's rooftop, regaining his backpack and continuing to run. However just as he began running, he was attacked by Black Panther, who had lost his father in the bombing. Without a word being spoken, Barnes and Black Panther began fighting as he used his Panther Habit to try and kill Barnes. As Panther tried to use his claws to cut Barnes' throat, he became distracted as a Joint Counter Terrorist Centre helicopter began shooting at the pair, only for Panther's Vibranium armour to protect him from the bullets. Barnes began to run again, with the Panther and Captain America running close behind him as they leapt down from the building and onto the street while the Falcon managed to knock the helicopter out of the way of danger to protect them all. Barnes used his momentary lead to run ahead of Black Panther and jumped down into a busy underground road, fleeing through the traffic while Black Panther and Captain America followed close behind him. Realising that Black Panther would be able to outrun him eventually, Barnes was able to get ahold of a man's motorbike and used the extra speed to get ahead in the chase while Rogers and the Panther used a stolen car to try and catch up with him. Despite his head start, Black Panther managed to catch up with Barnes and attempted to kill him, however Barnes was just able to use his Prosthetic Arm to block Black Panther's attack, grabbing him by the throat and knocking him into the road. While also grinding his hand across the tarmac to keep from falling off his bike and continued to ride away from danger while the still determined Joint Counter Terrorist Centre agents followed behind in their cars. Coming to the end of the tunnel, Barnes used an explosive to destroy the roof, hoping to trap his attackers and get away. However Black Panther was able to gain extra speed by jumping on Falcon's back and knocked Barnes off his bike before Rogers kept him from killing his friend. The manhunt was finished as War Machine cornered them and they were arrested by the Joint Counter Terrorist Centre, with Black Panther revealing himself to be King T'Challa of Wakanda.

Captured
"What the hell is this?" "Why don't we discuss your home? Not Romania. Certainly not Brooklyn. No, I mean your real home."

- Bucky Barnes and Helmut Zemo

With Barnes now in custody, he was locked in a containment cell with his cybernetic arm tightly fixed down and taken to the Joint Counter Terrorist Centre Building in Berlin, Germany. From within his cell, Barnes watched as Steve Rogers, Sam Wilson and T'Challa were greeted by Sharon Carter and the leader of the Joint Counter Terrorist Centre, Everett Ross, before Barnes was taken away to await his questioning. Barnes was later greeted by what was supposedly the psychiatrist Theo Broussard, who had been sent to interview Barnes and evaluate his mental well-being. "Broussard" claimed to only want to ask Barnes some simple questions in order to help him, but Barnes remained silent, only answering to say that he would prefer to be called Bucky rather than James while "Broussard" asked him about the horrors he had seen during his time with HYDRA. "Broussard" set off a blackout that cut the security cameras, and began reciting the trigger words that would reactivate Barnes' Winter Soldier Program training by using the Winter Soldier Book originally owned by Vasily Karpov. Unwilling to be a slave to HYDRA again, Barnes gathered all of his strength and attempted to break free of his restraints and stop "Broussard"'s plans, ripping his arms free and punching the glass in an attempt to escape. However, "Broussard" was able to finish saying the code words just as Barnes broke free and went into his compliant assassin mode, blind to all his loyalty to his friends. "Broussard"'s first question was about his mission in 1991 where he had assassinated Howard Stark and his wife, Maria Stark, in order to steal the Super Soldier Serum. "Broussard" demanded to know the location of the HYDRA Siberian Facility so he could unleash the other Winter Soldiers.

Escape from the Joint Counter Terrorist Centre
"Zhelaniye. Rzhavyy. Semnadtsat’. Rassvet. Pech’. Devyat’. Dobroserdechnyy. Vozvrashcheniye na rodinu. Odin. Gruzovoy vagon....Soldat?" "Ya gotov otvechat."

- Helmut Zemo and Winter Soldier

The Winter Soldier was then ordered by "Broussard" to fight and kill anyone who attempted to stop him, before getting escaping in a helicopter to seemingly prove his guilt for the recent terrorist attacks. The Winter Soldier was soon found by Steve Rogers and Sam Wilson, who were trying to question "Broussard", so the Soldier quickly fought and subdued the pair before heading back upstairs. Finding himself surrounded by Joint Counter Terrorist Centre agents, the Winter Soldier fought his way through until he was attacked by Tony Stark, who attempted to use an Iron Man Gauntlet to subdue the Soldier. Despite being hit by several shockwaves, the Winter Soldier was able to withstand them and attacked Stark, attempting to shoot him in the head, however Stark fought back and disarmed the Soldier before being subdued himself with a punch to the chest. Before the Winter Soldier could kill Stark however, Sharon Carter and Natasha Romanoff came to his aid and began fighting the Winter Soldier together, using their combined skill to try and subdue the assassin. However the Winter Soldier's remarkable strength allowed him to defeat the pair and smashing Carter against a table before attempting to use his Prosthetic Arm to strangle Romanoff to death, despite her attempts to reason with him. The Winter Soldier was again stopped from killing one of his own allies when T'Challa charged in and began fighting his enemy, proving that even without his Panther Habit he remained a fierce opponent to the Winter Soldier. The pair proved to be eventually matched as they each managed to briefly subdue the other until T'Challa was able to kick the Winter Soldier down a stairway where he managed to escape towards the rooftop. Having gotten to the helipad, the Winter Soldier ripped the cables away and prepared to make his escape from the building, however not before Steve Rogers found his friend and refused to allow him to leave. Using all his might, Rogers grabbed ahold of the helicopter and pulled it back down towards the helipad, with the Winter Soldier watching as Rogers managed to pull it towards the ground despite the Soldier's attempts to fly away. Seeing that Rogers would not allow him to leave, the Winter Soldier instead crashed the helicopter towards him, hoping to decapitate him with the blades. When Rogers survived, the Winter Soldier grabbed him by the throat as they fell into the river below. During the crash, Barnes hit his head and was knocked unconscious. Rogers then rescued his friend from drowning and took him to a warehouse as police helicopters continued their search.

Fighting Back
"He wanted to know about Siberia. Where I was kept. He wanted to know exactly where." "Why would he need to know that?" "Because I'm not the only Winter Soldier."

- Bucky Barnes and Steve Rogers

Later, Steve Rogers and Sam Wilson, not knowing if Barnes was still activated as the Winter Soldier or not, trapped his metal arm in a vice leaving him defenceless and unable to continue fighting or running. When Barnes woke up, he recognized Rogers, prompting him to ask Barnes whether it was him or the Winter Soldier speaking. Barnes replied that Rogers' mother's name was Sarah and that he had worn newspapers in his shoes, personal facts that only Barnes knew that were not in a museum. Rogers and Wilson discussed the situation, deciding they would not call Tony Stark and Wilson saying he knew a guy who could assist them in Stark's place. Barnes also revealed he was not the only Winter Soldier, and Helmut Zemo, the man posing as Doctor Theo Broussard, was seeking the program's Siberian training facility to presumably free the other Winter Soldiers from cryostasis, and then unleash them upon the world to cause chaos. Stealing a car, the three went to meet with Sharon Carter, who had recovered Captain America's Shield and the EXO-7 Falcon. While Rogers spoke with Carter, Barnes asked Wilson if he could move his seat forward in the car to give him more room, but Wilson refused, as he still disliked Barnes due to their many fights. When Rogers and Carter shared a brief but passionate kiss before she departed, both Barnes and Wilson smiled at their friend.

Having regained their equipment, the group met with Clint Barton, who had successfully rescued Wanda Maximoff from the New Avengers Facility and had also recruited Scott Lang into their cause. While Lang expressed his delight in being invited to join the fight, Barnes listened as he overheard an announcement saying that the nearby airport was being evacuated due to Iron Man's arrival and translated this for everybody else.

Clash of the Avengers
"I didn't kill your father." "Then why did you run?"

- Winter Soldier and Black Panther

With time running out to find Helmut Zemo before he reactivate the other Winter Soldiers, Barnes and the rest of the assembled members of Captain America's team arrived at the airport to locate him. Barnes and the Falcon took position inside the building while Rogers was confronted by Iron Man and the people supporting his views of the Sokovia Accords, advising Rogers to hand himself and Barnes over to Thaddeus Ross for questioning before the situation got even worse. When Rogers made his move, Barnes and the Falcon ran to their position, only to find themselves being followed and confronted by Spider-Man. When Spider-Man attacked and kicked Falcon away, Barnes tried to hit him but the hero caught his Prosthetic Arm and commented on how cool it was. A fight then broke out with Falcon and Spider-Man chasing each other while Barnes threw items at Spider-Man, only for them to be thrown back at him. As the fight continued throughout the airport, Barnes found the Falcon had been almost subdued by Spider-Man, who had used his Web-Shooters to pin him to a wall. When Barnes attempted to assist his ally, they were both knocked off a platform and pinned to the floor with Spider-Man's webbing. When Spider-Man tried to mock them, Falcon used Redwing to throw him out of the building, at which point Barnes mocked him for not doing that sooner. Rejoining the rest of his teammates, Barnes attempted to run for the Quinjet to escape, only to find that their path was blocked by Vision, who used the power of the Mind Stone to stop them and insisted that they surrender now before it was too late. As Barnes and Rogers' team faced off against Iron-Man's team, it became clear that their views of the Sokovia Accords would not change. Seeing no other alternative, Rogers ordered his team to fight and together they ran forward against their opponents. Barnes quickly found himself engaged in a one on one fight with the furiously vengeful Black Panther. As the battle raged on, Barnes managed to wrap his Prosthetic arm around the throat of the Panther Habit, while locked together, Barnes tried to insist that he was not responsible for the death of King T'Chaka during the Bombing of the Vienna International Centre, but Black Panther only questioned why he had run when confronted about it. Not accepting his plea of innocence, Black Panther managed to gain the upper hand and kicked Barnes across the runway. Once Barnes was on the ground and recovering from the blow, the Panther attempted to cut his throat with his claws. However, Scarlet Witch intervened and used her powers to stop Black Panther's hand inches before they cut Barnes, stopping him before he could kill his enemy; she then launched him across the runway. Having regrouped with Captain America, Barnes listened in as the group, including Hawkeye agreed that the only way to win this war was if a lot of them lost the battle of Iron Man's team while Rogers and Barnes escaped. Knowing that it would be almost impossible to reach the Quinjet without being stopped, Ant-Man volunteered to make a distraction, turning himself into Giant-Man and attacking War Machine while Barnes and Rogers ran to the Quinjet.

While Giant-Man caused chaos, Barnes and Rogers ran to the Quinjet, almost being stopped when the Vision tried to destroy a tower to block their path, although Scarlet Witch ensured it stayed up long enough for them to make it under. They were then confronted by Black Widow who considered stopping them, but knowing Rogers would not stop, decided to use her Taser Disks to keep Black Panther at bay while they escaped on the Quinjet.

While travelling on the Quinjet having escaped from Iron Man's team, Barnes asked Rogers what would likely happen to the members of the Avengers who were supporting his cause. Although Rogers claimed he did not know, he in fact knew that Thaddeus Ross would send them to the Raft Prison. Although Barnes questioned if his life was worth all this suffering, Rogers insisted that what he did while a HYDRA assassin was not his own fault.

Battle of the Siberian HYDRA Facility
"Do you even remember them?" "I remember all of them."

- Iron Man and Winter Soldier

Iron Man later discovered Barnes' innocence and followed them to Siberia to form a truce to capture Helmut Zemo. However, Zemo used security footage of Howard Stark's "car crash" to reveal Barnes was responsible, having been sent to steal the vials of Super Soldier Serum in Howard's possession. Iron Man, blinded by rage, attacked Barnes and did not listen to Captain America's explanation that HYDRA made Barnes kill them via brainwashing, resulting in a fight with both Barnes and Captain America.

Barnes attempted to flee through the top of the silo, but Iron Man destroyed the hatch. The fight ended with Barnes' bionic arm destroyed and Captain America disabling Stark's Arc Reactor, shutting down the the armor Stark was using. Now fugitives, the two fled, Captain America laying down his shield, as Stark's father was the one who created it.

Awaiting a Cure
"Sure about this?" "I can't trust my own mind. So until they figure out how to get this stuff out of my head, I think going back under is the best thing... for everybody."

- Steve Rogers and Bucky Barnes

Having been pardoned by Black Panther, who had secretly followed Iron Man to Siberia, and granted asylum in Wakanda, Barnes had the remains of his mostly-destroyed robotic arm removed. Shaken at how easily his Winter Soldier programming could be activated, Barnes willingly went back into cryogenic sleep until the Wakandan scientists could cure him of HYDRA's brainwashing. As Barnes went under the ice, Rogers stood by his friend and offered him support as he was frozen. Worried that the governments of the world would invade Wakanda for harboring Barnes, Rogers spoke with King T'Challa, who mockingly dared them to try, claiming that both Barnes and his father were victims and therefore he wanted to help Barnes find peace. Sometime later, Steve Rogers freed the rest of their allies from their cells in the Raft.

Personality
"This doesn't have to end in a fight, Buck." "It always ends in a fight."

- Captain America and Bucky Barnes

Bucky Barnes was extremely devoted, loyal, headstrong and patriotic and had a strong moral center. He was a good and close friend to Steve Rogers during their youth; he helped him when he got into fights and tried to cheer him up and look after him when Rogers' mother died. Best friends since childhood, they went through many trials and tribulations together. He was also protective of Rogers, as when he planned to enlist in the United States Army. Barnes tried to talk him out of it, as he knew he would die because of his physical condition and poor health.

Due to his advanced physiology however, Barnes survived his apparent death, but was found by HYDRA instead. Trained as a living weapon, Barnes became a new man so to speak as his memories and identity were constantly being wiped until he was augmented into the perfect assassin, the Winter Soldier. As the Solider, he was brutal and ruthless with an utter lack of conscience, and followed remorselessly on Hydra's any order. Even so, he still saved Steve Rogers from drowning after the Insight Helicarrier blew up. Although he states he did not know why he did such, it was due to Rogers reminding him of who he was, which he initially reacted with violence before finally accepting.

While he still holds a mostly serious demeanor, he is still shown to retain a sense of humor, as shown when he and Falcon both smiled with approval at Rogers' kiss with Sharon Carter and later as the two reminisced over earlier times in their friendship. His sense of humor can also be dry at times, as shown when he asked Wilson why he couldn't use his gadget on Spider-Man earlier to take him down.

Even though Barnes has regained his identity and former values, he has also developed a guilt-ridden conscience, and became deeply ashamed over his actions as the Winter Soldier. He previously stated that he has an absolute memory of every person he has killed, and knows that the fact he was brainwashed does not change the fact that he killed them. Fearing for his mental state and anyone around him (as Helmut Zemo was able to manipulate him with the Winter Soldier Program), Barnes ultimately decided that placing himself in cryogenic stasis until he can be cured of HYDRA's mental programming completely would be the best course of action.

Powers and Abilities
"He's fast. Strong. Had a metal arm."

- Captain America

Powers

 * Artificially Enhanced Physiology: Barnes was one of many prisoners of war used in Zola's quest to recreate the Super Soldier Serum. There were no apparent effects at the time of his rescue by Steve Rogers, but the changes wrought on Barnes' body were sufficient to let him survive plunging into an icy river at the bottom of a fall that should have killed him. Zola further refined Barns' body in the Winter Soldier Program, ultimately creating an enhanced soldier with abilities equal to the Captain America, and without psychological instabilities which continue to plague similar programs into the 21st century.
 * Superhuman Strength: Winter Soldier has strength that is seemingly equal to that of Captain America. Barnes's physical strength is enhanced to the early levels of superhuman condition by a series of treatments performed on him by HYDRA scientists. He has used his legs and flesh arm to kick and punch others with a display of strength that far surpasses normal humans and closely resembles Captain America's own abilities, but was matched when he faced off against Spider-Man and Black Panther.
 * Bionic Arm: HYDRA also removed the remnants of his severed left arm and replaced the missing limb with a cybernetic one. The bionic arm gives him superhuman strength superior to that of Captain America, though not quite on par with that of Spider-Man. Winter Soldier was able to rip open a S.H.I.E.L.D. armored SUV, rip apart Falcon's EXO-7 suit, and smash concrete by punching it. With his bionic arm supporting his already enhanced natural strength, the Winter Soldier was shown to overpower Captain America in a fight.
 * Enhanced Speed: Winter Soldier's speed is is enhanced beyond the peak of human potential, moving into the early levels of superhuman condition. Bucky's speed is comparable to that of Captain America, who can casually run at 30 miles per hour with ease, and still had trouble keeping up with Barnes.
 * Enhanced Durability: Winter Soldier's bones and muscles are apparently denser and more resilient than a normal human's. Arnim Zola's experiments fortified his form to the extent that he routinely leaps from significant heights onto hard surfaces and lands without any apparent injury.
 * Enhanced Stamina: Winter Soldier's musculature produces far less fatigue toxins during physical activity than the musculature of an ordinary human.
 * Enhanced Agility: Winter Soldier's agility is superior to that of an ordinary human. He has demonstrated the ability to leap on top of midsize cars in a single bound and do acrobatic flips avoiding gunfire into cover.
 * Enhanced Reflexes: Winter Soldier's reflexes are enhanced to extraordinary levels. His reflexes are responsive enough to catch Captain America's shield being thrown at him at a high velocity. He was also able to catch enemy grenades thrown at him, dodge fire from Falcon's Steyr SPPs, and leap on top of a moving car accelerating towards him with pinpoint accuracy.
 * Regenerative Healing Factor: Winter Soldier's body is able to heal with speed and efficiency beyond a regular human being, though he is unable to regenerate missing limbs. This may be one of the factors of his survival from the Swiss Alps. Also, the injuries he had received during his battle with Iron Man healed in a matter of days without bruises or scars.

Abilities

 * Master Martial Artist: Winter Soldier is an extremely skilled and formidable martial artist and hand-to-hand combatant, excelling at improvisation and weapons handling. He employs a mixed martial arts that include elements of Kali knife fighting, Boxing, Taekwondo, and Krav Maga. Receiving vast training from HYDRA, as well as the United States Armed Forces, Barnes became a master assassin who can slaughter dozens of enemies alone, take on extremely skilled combatants such as Black Widow and Black Panther with relative ease, being in charge of training the other Winter Soldiers, and going toe-to-toe with Captain America himself. The two engaged in a brutal one-on-one fight, both matching each other with every move, though Rogers was ultimately able to defeat him in their second duel. He later beat Rogers after being released by Zemo, catching him off guard. Barnes also single-handedly killed up to a dozen well-armed Quinjet pilots in a single encounter, and escaped uninjured. Bucky later overpowered a suitless Tony Stark, Sharon Carter, and Black Widow, all in rapid succession, though he was notably pressured when fighting against Black Panther.
 * Knife Mastery: Winter Soldier excels in knife fighting with an emphasis in Kali knife fighting. The Winter Soldier usually resorts to his combat knife in close quarters combat. He usually holds the knife in his natural hand and uses his bionic arm for support should he need more force to overpower a downward stab or toss it between hands to advance his assault.
 * Master Marksman: Barnes has expertise in handling firearms and was a remarkably precise shot, even prior to being turned into the Winter Soldier. During World War II, he shot a HYDRA operative that even Captain America did not see until he was down. As the Winter Soldier, he became an even deadlier marksman. He fired a single round through Black Widow's stomach and into a nuclear scientist that she was protecting, killing him. Winter Soldier is also capable of making long range shots without the use of a rifle, for example, shooting Nick Fury multiple times through the wall of Steve Rogers's apartment and from the top of another building. As the Winter Soldier, Barnes has caught and handled Captain America's Shield on two occasions and showed impressive ability in doing so.
 * Master Assassin: Winter Soldier is a master assassin. Ever since he's been brainwashed, Winter Soldier has lived in anonymity with most of the intelligence community not even believing he exists. He's been credited with over two dozen of HYDRA's most crucial assassinations in the last 50 years. He was even able to shoot Nick Fury while himself outside of Rogers' apartment, and shoot through Black Widow to take out his target.
 * Master Acrobat: Winter Soldier has shown expertise in using flips to evade fire such as when he flipped to cover when he was being shot at by Falcon's Steyr SPPs. He was also able to maintain balance of a moving motorcycle he was utilizing while engaged in a fight with Black Panther.
 * Expert Pilot: Winter Soldier was able to hijack a Quinjet after killing the pilot.
 * Multilingualism: Barnes speaks his native English, as well as fluent Romanian and seasoned Russian (albeit with a thick accent).

Winter Soldier's Arsenal
"Ballistics." "Three slugs, completely untraceable." "Soviet made?" "Yeah."

- Natasha Romanoff and Maria Hill



While working for HYDRA, the Winter Soldier carried a vast array of weapons for combat, adapting his uniform with customized holsters to carry them. He was also usually handed extra weapons by his support henchmen.
 *  : The Winter Soldier's weapon of choice in close quarters combat. He has two of them holstered with the hilts both facing opposite sides (one at the back of his utility belt and the other in the lower back of his uniform). He used it against Captain America while confronting him on the streets of Washington, D.C. and inside one of Project Insight Helicarriers.
 * : The Winter Soldier was equipped with this pistol during his Assassination of Howard and Maria Stark. Barnes used this semi-automatic pistol to destroy a nearby security camera which recorded his successful assassination.

 * : A very small gun that the Winter Soldier carried in the right thigh custom holster.
 * : A sub-machine gun carried on the back of his vest. Steve Rogers forced him to use it as he had to drop his assault rifle, but Rogers quickly disarmed him. He later used it to kill a Quinjet pilot at the Triskelion, stealing the jet to board a Helicarrier.
 * ' 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. The Winter Soldier was handed one of them by one of the mercenaries that accompanied him on the streets of Washington, D.C. while trying to kill Steve Rogers and Natasha Romanoff, using both the grenade launcher and the assault rifle against them. He lost it during the battle, but he obtained another in the Triskelion, and used to kill all S.H.I.E.L.D. pilots that were about to board their Quinjets and help Captain America.
 * : A heavy rifle that the Winter Soldier used as a sniper rifle during an assassination. He was captured in a photograph released by the press, but his image was so blurry and small that needed technological enhancements to be distinguished.
 * : Barnes took this machine gun from Black Widow's equipment locker on the Quinjet in order to investigate the HYDRA Siberian Facility with Steve Rogers. He carried it while navigating inside the base, but he was quickly disarmed when he and Rogers started a fighting Iron Man.
 * : A grenade launcher customized to fire Magnetic Disk Grenades. The Winter Soldier used it against Nick Fury's SUV, in an assassination attempt against Fury.
 * : A six-shot revolver-type grenade launcher, that the Winter Soldier used on the streets of Washington, D.C. against Steve Rogers and Natasha Romanoff. His first shot sent Rogers to the street down a highway, and he kept using it to destroy the cars that Romanoff used for cover until she also fell to the street.
 * : The Winter Soldier caught a grenade thrown against him by one of the S.H.I.E.L.D. agents protecting the pilots at the Triskelion, and quickly threw it inside a Quinjet to destroy it.
 * Winter Soldier Grenades: The Winter Soldier rolled a heavily-customized variant of the "Ручная Граната Наступательная (Ruchnaya Granata Nastupatel'naya)", a Soviet hand grenade, underneath a car towards what he thought was Natasha Romanoff, but was in reality just her PDA.

Other Equipment
"You have a metal arm?! That is awesome, dude!"
 * Uniform: HYDRA designed a lightweight tactical suit for Bucky, complete with a half-face mask in an attempt to conceal his true identity from the world. The uniform is constructed from nomex thread and kevlar fiber. The lightweight suit provides resistance to small arms fire, and has advanced flexibility for close quarters combat. In addition, he also sometimes wears bulletproof tinted goggles to further conceal his face and for eye protection.

- Spider-Man


 * Bionic Arm: HYDRA designed a special metallic bionic arm to replace Bucky's lost arm, which he lost after falling from the train. During his transformation progress, he started to gain control over his new arm, strangling a HYDRA scientist. His new arm has also a red star on its shoulder, hinting that the Soviets who operated as HYDRA's allies had also participated in the process of Barnes's transformation into the Winter Soldier.
