Bucky is the name of several fictional characters that were masked superheroes in the Marvel Comics universe. The original one, James Buchanan "Bucky" Barnes, was created by Joe Simon and Jack Kirby as a sidekick character in Captain America Comics #1 (cover-dated March 1941), published by Timely Comics (Marvel's 1940s predecessor). Decades later, the original Bucky was brought back from supposed death as the Winter Soldier in 2005 and then he becomes Captain America in 2008 after Steve Rogers was presumed to be dead, before returning as the Winter Soldier once more.
