Winter Soldier, also known as James Buchanan "Bucky" Barnes, is a Marvel Comics superhero who was first introduced in Captain America #1 in 1941. He was created by Joe Simon and Jack Kirby. Bucky was originally portrayed as Captain America's teenage sidekick, serving as his partner in the fight against the Axis Powers during World War II. However, in a tragic turn of events, Bucky was presumed dead after a mission gone wrong, leading to Captain America being frozen in ice and preserved for several decades. Decades later, Bucky was revealed to have survived the mission and had been brainwashed by the Soviet Union to become a deadly assassin known as the Winter Soldier. He possesses superhuman strength, agility, and endurance, as well as extensive combat training and knowledge of espionage. The Winter Soldier's most notable power is his bionic left arm, which is capable of crushing metal and firing energy blasts.
