During the dark days of the early 1940s, a covert U.S. Military experiment turned Steve Rogers into America's first Super-Soldier, Captain America. Throughout the war, Cap and his partner, Bucky fought alongside infantry and with a group of heroes known as the Invaders. In the closing months of World War II, Captain America and Bucky were both presumed dead in an explosion. Decades later, Captain America was found trapped in ice and revived in the modern world.
