He made his debut in late 1940 in Captain America Comics No. 1, fighting Nazis at every turn. Twenty years after World War II, he was found frozen in ice. Now a man living in the wrong time, he became the leader of the Avengers, and fought some of the Marvel Universe’s greatest villains: Red Skull, Baron Zemo, Batroc the Leaper, MODOK—and even Cap’s former sidekick, now known as the Winter Soldier.
