I'm no longer the Winter Soldier. I'm James Bucky Barnes.
Background
Personality
Bucky is loyal, brave, honest to a fault, headstrong, resilient, and has a strong sense of justice and honor; during the 1940s he was charming and a ladies man, in present times he tends to be more distant and self-contained.
As the Winter Soldier, Bucky was an elusive, dangerous, and amnesiac assassin. He was ruthless, brutal, and under the complete control of HYDRA. After Steve Rogers reminded him of his past, Bucky broke from his programming and saved his friend and former target from drowning.

Name figuring upon "The Wall of Valor" memorial wall at the SHIELD Science and Technology Academy.
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..
Steve Rogers’ best friend Bucky Barnes was a member of the Howling Commandos and a former member of the 107th Infantry Unit. He had been captured during the Italy campaign by Red Skull's HYDRA forces and experimented on by the Swiss HYDRA scientist Arnim Zola, with Rogers, re-branded as Captain America due to Project Rebirth, rescuing him from the facility. He joined the Howling Commandos in gratitude, specifying he was joining for Rogers, not for Captain America. On one mission to capture Zola, however, Barnes was thought to have died from falling down a crevice while pinned by HYDRA soldiers. However, thanks to the experimentation done unto him earlier, he survived and was recovered by Zola (who had presumably just been released by the SSR in exchange for information about HYDRA) and some Soviet agents, with his arm forcibly removed through surgical operation and replaced with a bionic arm, and presumably undergoing brainwashing to remove any memories of his former identity. However, he resurfaces decades later as the Winter Soldier, a brainwashed, mega-enhanced Super-Soldier doing dirty work for a mysterious organization. By the time of the end of the Cold War, he was kept so classified that most of the intelligence community had doubts that he even existed, and gained the codename "The Winter Soldier," acting as an assassin for the USSR and presumably HYDRA. He once had an encounter with then-KGB agent Nastasha Romanoff while she was protecting a nuclear engineer, where he managed to shoot out their protection vehicle's tires and also kill the engineer by shooting straight through her gut. His MO was using Soviet rounds that were from antiquated weapons and thus "untraceable." By the time of the 21st century, the hardened Winter Soldier has no memories of his former identity and that suits him just fine — he is simply a killing machine. The Winter Soldier is first seen in the film leading a herd of fake police to chase after Nick Fury. Eventually, the Winter Soldier shoots a bomb with a magnet that attaches itself to Fury's vehicle, which explodes and flips the car over. The Winter Soldier walks over to Fury, but he finds a hole in the ground where Fury should have been. Fury then limps over to Steve Rogers' apartment to attempt to tell him that SHIELD has been compromised.
However, the Winter Soldier manages to find where Fury is hiding and shoots Fury through the wall, three times, seemingly killing him. Steve chases after the Winter Soldier and attempts to throw his shield at him, but is shocked when the Winter Soldier catches it, and throws the shield back at Steve before disappearing.
Later, Natasha reveals to Steve that the Winter Soldier has been responsible for many assassinations for 50 years. After Steve and Natasha escaped Hydra once again, Rumlow requested the Winter Soldier's help. ("Call in the asset")
Alexander Pierce, the official head of the reorganized HYDRA terrorist group operating within SHIELD, finds the Winter Soldier in his apartment, and tells him to assassinate Captain America and Black Widow, wanting their confirmed deaths in ten hours. However, Pierce's house-keeper stumbles upon their meeting and sees the Winter Soldier, resulting in Pierce shooting her with the Winter Soldier staring unfazed.
