Bucky Barnes

Bucky Barnes is a character from the Marvel Universe and is remembered more as a Winter Soldier than the regular Bucky
During World War II, Bucky appears as:
A loyal friend and trusted ally, he's been Steve Rogers' best friend since childhood and always stood up for him.
A responsible and compassionate person. He did not tolerate violence and did not tolerate injustice.
Brave and proactive, he stood up for Steve as a teenager when hooligans tried to rob him. During the war, he served Captain America with distinction and was a member of the Invaders.
Possessing a sense of humor, despite his rigorous duties, Bucky never lost his ability to joke around with his comrades. After his "death" during the war, Soviet intelligence found Bucky and implanted a program in his mind, turning him into a killing machine. In this state, he:
He lost his own will. He acted as if he were carrying out orders, feeling no remorse about the periodic memory wipes.
He became cruel and merciless. He lost the capacity for compassion, completely succumbing to the programming. As his memories returned, Bucky was overcome with a deep sense of guilt for the murders he committed as the Winter Soldier. He remembered every life he had taken and did not consider brainwashing sufficient justification. In Wakanda, after being cured of the Hydra program with Shuri's help, Bucky earned the nickname White Wolf and attempted to start anew. He sought to atone for his past by living quietly and trying to avoid attracting attention.
