Captain America has become a very public face for Marvel comics, billed as the “First Avenger” and known as the moral center of Marvel's universe.

The only problem with that is that Marvel didn't create him.

He was actually created by Joe Simon and Jack Kirby, the latter of whom later helped Stan Lee create heroes such as the Fantastic Four, the Incredible Hulk, Thor, and the X-Men.

The first Captain America comic debuted in 1940, when many Americans were hungry to enter World War II.

Captain America didn't make his Marvel debut until The Avengers No. 4, complete with the now-familiar back story about being frozen in ice.
