Either Captain America was based off of DC's Commander Steel, or vice versa. Whoever came out second was based on the other. The similarities are uncanny. They're both patriotic super-soldiers with super-strength and they're both members of the two main teams in Marvel/DC (Avengers/Justice League). Heck, in the series finale of Justice League Unlimited, Commander Steel uses a shield to save Hawkgirl from a parademon.
