Ah Cap, brought to us originally in March 1941 he was one of the few patriotic characters that came out at the time that survived all the way till now. Someone realised that he doesn't just have to be fore WWII, he can be for every war. And as America, we are in a lot of those :D
He was said to be the counter to DC's Superman. Seriously.
But his birthday according to Marvel is, you guessed it, the Fourth of July.
So happy birthday to the Avenger we here think you should have taken the side of during Civil War.
