Erik Larsen's Savage Dragon has fought with all manner of menaces over his career. Early on, he teamed with Hellboy to fight one of history's greatest villains, Adolf Hitler. The pair prevailed, but that wasn't the end of the Nazi menace for our heroes. They saved Hitler's brain - why do they always do that - and transplanted it into the skull of a superhumanly powerful monkey. And thus was created Brainape. The Dragon has also gone toe-to-toe with a gigantic Osama Bin Laden as well.
