From Brooklyn, New York on Earth, James Buchanan Barnes (a.k.a "Bucky") was a Sergeant in the U.S. Army during World War II and later joined Captain America's Howling Commandos. He was stationed in Europe and ended up a Prisoner of War with the Nazi scientific branch known as HYDRA until he was later freed by Captain Rogers. During captivity, he was the sole survivor of intensive experimentation that enhanced his body enough to assist in surviving an otherwise deadly fall over a year later that landed him back into HYDRA's hands. After further experimentation, training, brainwashing and memory wipes, Barnes was made into one of Earth's deadliest assassins and was kept in cryogenic stasis in between missions over the course of 70 years. He is codenamed The Winter Soldier.

Executes missions impersonally and efficiently. Humanity is mostly repressed, though that may change with the absence of his former oppressors and the recent return of some memories. An inherently good man whose perceptions of morality have been fiercely warped; how much good remains or is salvageable is currently uncertain. At this stage, he is unpredictable, likely to become unstable under certain stimulus due to trauma, but for now remains suitably controlled through force of will. Social skills are minimal, emotional responses are impaired and likely to default to varied degrees of anger or disassociation. Self knowledge and self expression are a work in progress, though some recovery of lost identity is not impossible.
