Marvel's Avengers Assemble Wiki

James Buchanan "Bucky" Barnes was a former soldier in the U.S. Army during World War II and the best friend of Steve Rogers since childhood. He was later brainwashed and turned into a HYDRA assassin under the moniker of the Winter Soldier.



Bucky accidentally walked in on Steve Rogers changing into his uniform, thus discovering his friend was Captain America, and insisted that he join him. He underwent extensive training and was assigned to be Captain America's partner. Together, Bucky and Steve fought in many battles throughout the war, alongside James Howlett and Robert Frank.

In the closing days of World War II in 1945, Bucky was believed to have been killed in action. In reality, he survived and was taken to Belarus and experimented on by Baron Heinrich Zemo, Red Skull, and Arnim Zola. Bucky was brainwashed and given a variant of the Super Soldier Serum and a cybernetic arm, turning him into the HYDRA assassin Winter Soldier.


In modern times, the Winter Soldier infiltrated the Avengers Tower to abduct the Red Skull, who was being imprisoned by the Avengers at the time. He used the Aven-Jet as a distraction to escape into the sewers, where Captain America followed him. Steve tried to convince the Winter Soldier to give the Skull back, as he had valuable information on Thanos, but Bucky knocked him out and escaped by climbing on a train. Captain America caught up with them, but the Winter Soldier escaped in a drone and caused an explosion in the train tracks to slow him down. Falcon used a tracking device that Black Widow had put in the Red Skull to pin the Winter Soldier's location to a missile silo in New Jersey. After pinning the Red Skull to one of the missiles, the Winter Soldier found the tracking device and destroyed it. Having realized the Avengers would come for him, Bucky launched all the missiles at the base. Captain America and Falcon tracked down one of the missiles headed to Belarus, the place where the Winter Soldier had been created, as the rest of the team dealt with the other missiles. On the missile, Captain America was confronted by the Winter Soldier after trying to free the Red Skull. Captain America tried to make the Winter Soldier understand that if he let the missiles hit their targets, he would only finally become what the Red Skull wanted: a villain. With 27 seconds for impact, the Winter Soldier escaped the missile, but not before warning Captain America about the time limit for some reason. Captain America would manage to disarm it with the help of the Falcon.


When Captain America, Thor, and Iron Man destroyed the "power amplifier" that Ant-Man built for Doctor Spectrum, Spectrum used his power prism to unleash the fears and regrets of the three Avengers. In Cap's case, it was his guilt over his involvement in Bucky becoming the Winter Soldier. The prism's nightmare version of Winter Soldier claimed that Cap had left him to die and that he was lying to himself when Cap stated he tried to save Bucky. Cap was able to defeat Nightmare Winter Soldier by admitting that his inability to save Bucky was something he would always have to live with, causing Winter Soldier to return to the power prism.

Personality and Traits[]

Originally, Bucky was very much like Falcon, but after he was brainwashed, he became a stone-cold mercenary, though there could still be some good in him. Once he is freed from HYDRA's control, he desires nothing but vengeance towards Red Skull for what he did to him.



Captain America[]

Steve Rogers was Bucky's best friend during and before the war against the Axis Powers and HYDRA. While never suspecting that the clumsy army private whom he befriended during his beginning years was the American hero and idol whom he cherished, Captain America. Until the day he stumbled upon Rogers while changing into his costumed alter ego, not losing any respect for his friend and his hero, Bucky became a loyal vassal to the star-spangled icon as the two pressed on against the forces of Johann Schmidt, The Red Skull, nearing the end of WWII. Decades later, after Cap and he himself were presumed dead when the Soviet Winter Soldier was backed by the Skull's Hydra initiative, Bucky Barnes became rather embittered with his old friend as well as the world at large. He was somewhat ashamed of himself and angry at Steve for not saving him when he needed it most.

Red Skull[]

Barnes deeply despises Red Skull for the torturous physical and mental modifications he suffered under the Winter Soldier program. Initially, only an American patriot fighting against the Nazi's and Hydra's plans of global conquest as Captain Steven Rogers's sidekick, his training and abuse under the Skull's machinations left lasting psychological scars that damaged Barnes's psyche and persona. The reason for his kinder and moral characteristics being eaten away over the course of decades was that he was used as the attack dog of other greedy and apathetic individuals with ties to Hydra.

Powers and Abilities[]


Artificially Enhanced Physiology: Barnes was subjected to Hydra's Super Soldier Serum, giving him superhuman physical abilities.

  • Enhanced Strength: Bucky possesses superhuman strength, enough to go toe-to-toe against Captain America and hurt him through his durability with his right hand. His left arm is cybernetic, has greater strength than Captain America, and restrains Black Panther, in which he was falsely accusing him of killing Captain America.
  • Enhanced Speed: He has proven to be just as fast as Captain America. Through years of rigorous training, he has increased his speed beyond Captain America's limits.
  • Enhanced Agility: He has shown slightly more agility than Captain America.
  • Enhanced Stamina To be added
  • Enhanced Reflexes To be added
  • Regenerative Healing Factor: His blood has a regenerative healing factor in its system, which regenerates his injuries at an accelerated rate. It seems unlikely that he can regrow limbs. This constant cellular regeneration is causing his aging process to come to a complete stop. This healing factor makes him very difficult to kill.


Master Hand-to-Hand Combatant

  • Master Hand-to-Hand Combatant: Barnes has mastered several forms of martial arts. He is shown to be skilled enough to rival the likes of Captain America.
  • Master Marksman: He is also a master-level marksman.
  • Espionage Agent: He is a master of manipulation, tracking, marksmanship, tactical analysis, espionage skills, assassination, and computer hacking. He also has other espionage skills such as vehicular driving, escaping, disguise, gadgetry, weaponry, and thievery expertise.



  • Winter Soldier's Suit: His standard uniform comes with a glider webbing for which he can soar on air currents.
  • Bionic Robotic Arm: Barnes' left arm was replaced with a cybernetic prosthetic, which further served to bolster his physical strength. The replacement limb was created to compensate for the loss of his left arm when Barnes fell in the war. Aside from acting as a functional limb, the arm also has a couple of useful features and weapon modifications.
    • Hacking Capability: The limb's own AI enables the user to hack into and infiltrate even the most advanced security systems
    • Wrist Laser: Bucky's robotic hand sinks into the wrist, revealing a plasma caster able to fire lasers powerful enough to blow holes in large missile casings.
  • Taser Coil: Electrified stun cable latches onto and shocks a target into unconsciousness.
  • Knockout Gas: A sleeping vapor capsule is potent enough to knock out Gamma Mutates and Asgardians. Used by Bucky to incapacitate Hawkeye, Hulk, and Thor while infiltrating the tower.


  • Energy Rifle: Winter Soldier's regular equipment cache consists of a potent energized firearm with a great many weapon capabilities. It has an under-and-over gun barrel style, similar to a battle rifle with a grenade launcher added to it. The main gun fires charged particle blasts, while the mini-gun casts plasmite charges capable of wrecking infrastructure. He was forced to throw the gun in mid-air in order to keep it from blowing up Bucky.
  • Laser Whip: When he was fighting Black Panther, he used his laser whip to battle Black Panther, in which it somewhat failed, because of the martial arts that Black Panther was able to use.

  • In the Marvel's Spider-Man, Bucky has been redeemed.
  • According to Black Widow, the programming didn't go so well for either Red Skull or Bucky, which means that Winter Soldier must have betrayed the Red Skull at some point.
  • At the end of The Vibranium Curtain Part 1, he remarked to Tony regarding Captain America's presumed death, "If you keep me from trying to take him, then you and I are going to have a problem." Emphasizing the fact that it was Tony's fault that he falsely accused Black Panther when Black Panther was trying to explain the entire issue of the crown killing Captain America.
