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, he was well-spoken, funny, charming, and a great dancer. In present times he tends to be more distant and self-contained. He's grumpy, reserved and doesn't like interacting with people.

As the Winter Soldier, Bucky was an elusive, dangerous, and amnesiac assassin. He was ruthless, brutal, and under the complete control of HYDRA.
