A crash course in the threequel's prospective big baddie
When the Avengers fished Captain America out of the ocean in 1964′s Avengers #4, it was revealed that the hero had seemingly met his demise at the end of World War II and been preserved in ice until the modern day. The thing is, that story had never been told in the comics. In fact, Captain America survived World War II and appeared in a number of comics in the 1950s – including "Captain America Comics" and the incredibly-1950s-sounding "Young Men" and "Men’s Adventures". Avengers writer Stan Lee had even written some of those adventures, a fact that he says he forgot when he concocted the resurrected Cap’s tragic new back story.
Years later, "Captain America" writer Steve Englehart was not content to let the 1950s stories exist outside of canon and instead chose to challenge the inconsistencies head on. In 1972′s "Captain America" #153, he introduced the idea that every adventure that took place after 1953′s "Young Men" #24 and before Cap’s return in 1964 had actually starred a replacement Captain America and Bucky. Englehart brought the 1950s Cap back to active duty – and he wasn’t brought back to play nicely with Steve Rogers and the Falcon.
