Winter Soldier

"I'm with you 'til the end of the line, pal."

- James Barnes to Steve Rogers

Sergeant James Buchanan "Bucky" Barnes was a soldier of the 107th Infantry Regiment and the childhood friend of Steve Rogers. During World War II, he became a member of the Howling Commandos. They attacked many HYDRA bases together. During a battle on a HYDRA train, Barnes was attacked and fell off the train.

He was then assumed to be deceased, but he actually survived, though he lost his left arm. Brainwashed and armed with a new cybernetic limb, he eventually became an enhanced HYDRA operative known as the Winter Soldier. Over the next decades, he would assassinate everyone who posed a threat to HYDRA, including his former ally Howard Stark, spending time between missions in a cryogenic state. However, when he was ordered by Alexander Pierce to assassinate S.H.I.E.L.D. Director Nick Fury, he was confronted by his old friend, Steve Rogers, which caused him to begin remembering who he really was.

In the aftermath of the Battle at the Triskelion, the Winter Soldier went on the run from HYDRA on a mission to remember his past and end his violent history. However, during this time he was accused of assassinating the King of Wakanda, causing the Black Panther to hunt him down. Barnes was saved by Captain America, sparking the Avengers Civil War as Barnes 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 was behind the devastation. Barnes was then taken to Wakanda where he could be frozen until his mind could be cleansed of the mental programming implanted by HYDRA.

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

- Steve Rogers and Bucky Barnes after Sarah Rogers' funeral

James Buchanan Barnes was born on March 10, 1917, the oldest child of four, and grew up to become an excellent athlete who also excelled in the classroom. During his childhood, he met Steve Rogers when bullies were trying to steal his money. . The two became best friends and stuck together for years. In 1940, Steve's mother, Sarah Rogers, died of tuberculosis. After her funeral, Barnes walked Rogers home and tried to offer him help with rent, but he 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 he did not have to because, as he placed a caring hand on his friend's shoulder, he was with him "'til 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
"This isn't a back alley, Steve. It's war!"

- Bucky Barnes to Steve Rogers

Barnes, along with the rest of the 107th Infantry, 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 defense of his friend and quickly sent the bully running away. Barnes learned that Rogers had been attempting to enlist in the army again, 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 day. At first, Rogers seemed upset, as he was not shipping out to war with his best friend. Bucky, however, was determined to cheer his friend up. 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. When Rogers asked what Barnes had told his date about him, Barnes simply replied, "only the good stuff." While exploring the Expo, the group watched Howard Stark demonstrate his prototype flying car, which greatly impressed Barnes, until it malfunctioned and fell to the ground. When Barnes turned around to suggest the group go dancing, he saw that Rogers had walked away from the group. Though Barnes was having fun, Rogers was interested in attempting to enlist for the fifth time. Barnes found him 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 Connie and Bonnie. Barnes and his unit, the 107th then 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, he met other Allied POWs: including Jacques Dernier and James Montgomery Falsworth. During his stay in the facility, he was viciously beaten by the commander of the compound, 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 an isolation clinic. There, he was forced 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. As the freed POW's battled against the HYDRA forces, 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. After a brief fight, Schmidt revealed to them his true demonic face before escaping. Rogers and Barnes began working out an escape route in which they used a support beam to move to a safe section of the facility. They were 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.

Howling Commando
"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 joined them in a pub and convinced them to join his crusade against the Nazis and HYDRA, forming an elite group of fighters that would eventually be 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, Barnes had to deal with the realization that Rogers was now the one who gets flirted with, not him. Eventually, Barnes and the newly formed Howling Commandos joined Captain America on the battlefield once again. Over the following months, Barnes, Rogers, and 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 Commandos from the HYDRA enemy.

"Death"
"I had him on the ropes." "I know you did."

- Bucky Barnes and Steve Rogers

At the beginning of 1945, Barnes and Captain America prepared for a mission in which they would board a HYDRA train carrying Arnim Zola, with the aim of capturing the HYDRA scientist. Looking at the danger of the mission, Barnes joked that Rogers was getting payback for a time Barnes made Rogers ride a roller coaster that made him throw up. 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 Gabe Jones stayed on the roof of the train, Barnes and Steve Rogers entered and began exploring the carriages. Moments after their arrival, they were split up and ambushed by a team of HYDRA soldiers. 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 kill the final soldier when Rogers distracted him. Barnes claimed that he had him on the ropes and Rogers assured him that he believed him. Before they could relax, another HYDRA soldier appeared behind them and fired at them with a HYDRA Assault Rifle, blowing a hole through the side of the train. Barnes picked up Captain America's Shield and fired at the soldier, but he was shot again with the assault rifle, the power of the blast throwing him off the train. Rogers was able to dispatch the soldier and attempted to rescue Barnes as he hung off a rail on the side of the train. However, the rail snapped before Rogers was able to save him, which resulted in Barnes falling into an icy river below.

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 he lost his left arm. 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, continuing his experiments. In the care of the newly recreated HYDRA and now working underneath S.H.I.E.L.D.'s nose, Barnes underwent further experimentation at the hands of Arnim Zola and various other doctors, 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 was also subjected to multiple 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 for his greatest enemy. 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 certain missions. Over the next 50 years, the Winter Soldier would be responsible for numerous assassinations, killing all sorts of targets, from scientific minds to political figures. 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 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, 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 crawled from the car to attempt to escape.

Winter Soldier grabbed ahold of Stark with his robotic arm as Stark begged him to save his wife's life. As Stark looked up at his assassin, he recognized him and even addressed him by his real name. However, 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 CCTV cameras.

Training other Winter Soldiers
As HYDRA's enemies continued to grow, 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 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 him, then they were accepted into the program.

During one of these training sessions, the Winter Soldier was defeated by Josef and as result, Vasily Karpov came in to congratulate the victor. However, a riot began with the other soldiers rising up against their captors and attacking Karpov. As a fight broke out, the Winter Soldier protected Karpov and got him away from danger while the HYDRA guards eventually subdued the other soldiers before putting them back into Cryostasis Chambers.

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 he made his way to the vehicle to finish Fury, he found his target had used a laser cutter to escape from his wrecked car and into the sewers to escape his would be assassins. Barnes later located Fury at Steve Rogers' apartment, where he was attempting to give Rogers vital information about his attack. Before Fury could reveal his information, Barnes shot him in the chest multiple times through the wall from another building. 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.
"I have her. Find him."

- 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 lept 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.

Search for the Truth
"I'm not gonna fight you. You're my friend." "You're my mission. You... are... my... mission!" "Then finish it. 'Cause I'm with you 'til 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 destroyed the machinery and beat up the scientists that created him before leaving to get away from his violent history. Barnes later went to the Smithsonian Institution's Captain America Exhibit where he found a memorial for a Howling Commando named James "Bucky" Barnes who had seemingly been killed during World War II. Afterwards, Barnes traveled to an old Romanian safehouse.

Found by Captain America
"Buck, do you remember me?" "Your mom's name was Sarah; you used to wear newspapers in your shoes."

- Steve Rogers and Bucky Barnes

Remembering the sins he commited when he was brainwashed by HYDRA, Barnes was on the run from the government. He travelled to an old Romanian safehouse to investigate his past. While walking through Romanian capital Bucharest, Barnes discovered he was being accused of the Bombing of the Vienna International Centre in Austria. He would come to his hideout to find Captain America was already there. Their re-union would eventually be interrupted by the arrival of German special forces. Captain America and Falcon tried to help Barnes escape as both the law enforcement and Black Panther - who lost his father in the bombing - pursued him. The manhunt was finished once War Machine cornered the escapees. The captive Barnes, Rogers and Wilson were brought to the Joint Counter Terrorist Centre Building in Berlin, Germany. There Barnes was locked in a containment cell with his cybernetic arm tightly fixed down. Helmut Zemo, under the guise of psychiatrist Theo Broussard, was sent to interview Barnes and evaluate his mental well-being. Zemo set off a blackout that hid his actions from the security cameras, and reactivated Barnes' Winter Soldier Program training by using the HYDRA manual he procured from Barnes' former handler Vasily Karpov, which led Barnes attempting to break free of his restraints and stop Zemo's plans, ripping his arms free and punching the glass to try to escape. However, Zemo was able to finish saying the codewords just as Barnes broke free and became his willing assassin. Zemo ordered Winter Soldier to fight and kill anyone who attempted to stop him, before getting into a helicopter and escape to seemingly prove his guilt for the bombing. As the Winter Soldier obeyed his orders, the escape attempt was thwarted by Rogers. Later, Rogers and Sam Wilson eventually managed to lock Barnes down on a remote location where he was trapped with his arm caught in a vise, leaving him defenseless and unable to continue fighting or running. Rogers asked if Barnes knew who he (Steve) was. Barnes replied that his mother's name was Sarah and that Rogers had worn newspapers in his shoes; personal facts that brought a smile to Rogers' face. 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 Zemo was seeking the program's Siberian training facility to presumably free the rest from cryostasis, and unleash them upon the world.

Zemo's Pawn
Knowing that the Accords would never allow them to stop Zemo in time, Rogers assembled his own team of Avengers to confront Zemo and the Winter Soldiers in Siberia. Joining his old friend's team of Avengers, but meeting another group of Avengers led by Iron Man who fought to capture them, Barnes ended up being the only one to flee with Captain America in a Quinjet to follow Zemo. Iron Man later discovered Bucky's innocence and followed them to Siberia to form a truce to capture 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 flew into a rage and attacked Bucky, 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 Bucky's bionic arm broken and Captain America destroying Stark's arc reactor, shutting down the the armor Stark was using. Now fugitives, the two fled, Captain America laying down his shield.

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, while Steve Rogers freed the rest of their allies. Barnes willingly went back into cryogenic sleep as punishment for the sins HYDRA made him commit and until Wakandan scientists could cure him of his brainwashing. As Rogers worried that the United Nations and Iron Man would hunt T'Challa for allowing Rogers and his fellow Avengers refuge, including Barnes, T'Challa mockingly dared them to try.

Personality
Bucky Barnes was extremely devoted, loyal, headstrong, 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.

Out of the two friends, Barnes would be considered the more attractive and the more flirtatious; however, when Rogers transformed into Captain America, Barnes was a bit jealous of the attention now bestowed to his once sickly friend.

After his apparent death from falling off a train, Barnes returned as the Winter Soldier, an elusive, dangerous and amnesiac assassin. He was ruthless, brutal and under the complete control of HYDRA. After Captain America reminded him of his past, Barnes seemed to break from his programming and saved his former friend and current target from drowning. While he still holds a mostly serious demeanor, he is still shown to retain a sense of humor, as shown when he and Sam Wilson both smiled with approval at Steve Rogers' kiss with Sharon Carter and later as the two reminisced over earlier times in their friendship. His sense of humor can also be dried at times, as shown when he told Wilson he couldn't use his gadget on Spider-Man earlier to take him down.

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

- Captain America

Powers

 * Artificially Enhanced Physiology: After Bucky Barnes fell into a trench in an ice mountain, he was saved and given a metal arm, along with other enhanced abilities from a serum that had a similar effect on the human body as the Super Soldier Serum given to Steve Rogers.
 * 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.
 * 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 comparable to that of Captain America. It should be noted that Captain America can run at 30 miles per hour with relative 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 biology has regenerative abilities, similar to Captain America. He can heal at high speeds, though he is unable to regenerate missing limbs. This may be one of the factors of his survival from the Swiss Alps.

Abilities

 * Master Martial Artist: Winter Soldier is a highly trained martial artist and excels at improvisation and weapons handling. The Winter Soldier 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 Falcon, Black Widow, and Black Panther with relative ease, and go toe to toe with Captain America. 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. Barnes also single-handedly killed up to a dozen well-armed Quinjet pilots in a single encounter, and escaped uninjured.
 * 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.

 * Expert Pilot: Winter Soldier was able to hijack a Quinjet after killing the pilot.
 * Multilingualism: Barnes speaks fluent English, Romanian and seasoned Russian.

 * 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.
