James Buchanan "Bucky" Barnes is the best friend of Steve Rogers from childhood who was thought to have died during World War II, while on a mission with Captain America. However, decades later he was revived as the assassin codenamed "The Winter Soldier".
He appears in the final scene "End Of The Beginning" in footage from Captain America: The Winter Soldier. As he survived the events of the film, he could potentially have an impact, or even appearance, on the developing life of the team.
