Scarlet Skull

Origin
The Scarlet Skull was a mercenary and assassin who allied himself with the Nazi spy mastermind, Sinhart, and his partner, The Condor. The three had developed a plot to kill the President of the United States and replace him with Condor, who had made himself the President's double. Unfortunately the whole plot was thwarted by the hero, Daredevil.

The Skull was actually an ordinary man wearing a skull mask, but he considered himself too ugly to be seen without the mask. He managed to sneak up on Daredevil twice and knock him out once, but he wasn't much of a match for Daredevil face to face. He used conventional weapons such as guns, knives and clubs.
