Congressman James Buchanan "Bucky" Barnes is a World War II veteran, former sergeant of the 107th Infantry Regiment, the best friend of Steve Rogers since childhood, and a founding member of the New Avengers. Barnes joined the United States Army following the attack on Pearl Harbor and was assigned to the 107th in 1943. His unit was captured by Hydra, where Barnes was injected with the Super Soldier Serum by Arnim Zola before he was rescued by Rogers, who had become Captain America. Barnes and Rogers then formed the Howling Commandos to battle Red Skull's forces. However, during the attempt to finally capture Zola in the Austrian Alps in 1945, Barnes plummeted hundreds of feet. As no body was recovered, Barnes was presumed deceased and was honored as a hero who died in service to his country.

Unbeknownst to his team, Barnes' enhanced abilities allowed him to survive the fall, albeit with the loss of his left arm. Once he was found by the Soviet Armed Forces and Hydra, Barnes was brainwashed and armed with a new cybernetic arm in order to become a super soldier assassin known as Winter Soldier. Over the next seventy years, he killed anyone who posed any kind of threat to Hydra or the Soviet Union, including John F. Kennedy, as well as Howard Stark and his wife, Maria. Between missions, Winter Soldier was placed into cryogenic stasis to ensure his longevity. In 2014, Winter Soldier was ordered by Alexander Pierce to kill Nick Fury, in order to ensure that all Pierce's schemes with Project Insight could go ahead. However, Winter Soldier was challenged by Captain America, leading to him to begin remembering his prior life.

In the wake of the Battle at the Triskelion, Barnes, now free, deserted Hydra in order to remember his past and regain his agency. Two years later, Barnes was framed by Helmut Zemo for the bombing of the Vienna International Centre, which claimed the life of T'Chaka. As Black Panther targeted Barnes in order to avenge his father's death, Barnes was repeatedly saved by Captain America, which sparked the Avengers Civil War as a team of Avengers led by Iron Man was sent to capture him. Zemo revealed to Iron Man that Winter Soldier had murdered Stark's parents years ago. Having survived Stark's attempt to kill him, Barnes was given amnesty in Wakanda by T'Challa and was placed in cryostasis until the Hydra Winter Soldier programming could be removed from his mind.

By 2018, with the help of Shuri, Barnes was finally cured of his brainwashing and earned the nickname White Wolf while living in Wakanda. However, as Thanos attempted to kill Vision for the Mind Stone, Barnes received a vibranium arm and joined the defense of Wakanda. Winter Soldier defeated many of the Outriders alongside Rocket, only for Thanos to defeat them and assemble all of the Infinity Stones. Barnes was killed when Thanos eliminated half of all life in the universe. Five years later, Barnes was resurrected by Bruce Banner and participated in the final battle against Thanos. In the aftermath of the battle, he attended Stark's funeral with all the other heroes. Later on, Barnes bid Rogers farewell, knowing of his intention to time travel back to the 1940s. Barnes then witnessed Rogers, as a much older man, return home in order to pass the shield onto Sam Wilson.

With his name pardoned, Barnes sought atonement for all his actions as the Winter Soldier. His attempts were interrupted when John Walker was made the next Captain America, and the Flag Smashers emerged to act against the GRC's efforts to handle the aftermath of the Blip. He and Sam Wilson would go on a mission to stop the Flag Smashers, working with Zemo and Sharon Carter. However, their mission was complicated by Walker's attacks, until Walker murdered a Flag Smasher over Battlestar's death. Barnes and Wilson were forced to defeat Walker to stop him from continuing to be Captain America. Barnes would then join Wilson and Walker in the final battle with the Flag Smashers, helping in their defeat and making amends with his past. The next year, he was attacked by Nebula, who stole his arm so that she could give it to Rocket as a Christmas gift. By 2027, Barnes entered into politics and began a campaign to get elected into the United States Congress.

Halfway through his term in Congress, he worked to gather incriminating information against Valentina Allegra de Fontaine for her upcoming impeachment hearing. This pitted Barnes against Valentina’s former assassins, although he would eventually work with them against de Fontaine. With them, he would go on to confront de Fontaine in the Watchtower, only to be forced to retreat by the genetically modified Sentry. As soon as New York was attacked by the Void, Barnes worked with his newfound team to stop the threat, letting themselves be engulfed by the void to aid Yelena Belova in trying to convince Sentry to fight the Void, his dark ego, for control. They eventually succeded and returned, where, in an attempt to confront de Fontaine, Barnes and the others were dubbed as the New Avengers.

In the Marvel Cinematic Universe (MCU), Bucky Barnes (James Buchanan Barnes) transitions from a charming, fiercely loyal WWII soldier to a traumatized, silent assassin, and finally to a recovering man searching for peace and purpose.

Pre-War / 1940s Persona

• Charming and Charismatic: Before the war, Bucky was laid-back, popular, handsome, and comfortable in social settings.

• Patriotic & Selfless: As a sergeant in the 107th Infantry, he had a strong moral center, putting others before himself and serving his country with honor.

The Winter Soldier Persona

• Conditioned & Robotic: After falling from the train and being captured by Hydra, Bucky suffered decades of physical and psychological trauma, memory wipes, and cybernetic enhancement.

• Rigid & Restrained: As an assassin, his behavior became mechanical, silent, and hyper-focused on executing orders.

• Haunted by Memory: Unlike Steve (who was haunted by what he lost), Bucky was tormented by the full, terrifying weight of everything he remembered doing while under Hydra's control.
