7. Baron Blitzkrieg

Well, he's a Nazi.

The Baron began as a ruthless officer of the German army during World War II. But some nameless hero of a concentration camp prisoner hit him in the face with a bottle, blinding and disfiguring him. He was given back his sight, but remained horrific looking, so he got himself a sweet helmet to hide his visage. As a consolation prize, the Nazi scientists gave him super powers. Blitzkreig fought Wonder Woman and the All-Star Squadron numerous times.

He eventually founded the super villainous organization known as Shadowspire, which sounds like a really cool Dungeons and Dragons module. Working with fellow supervillain Vandal Savage and his supervillain organization Symbolix, the Baron helped to create the superhero known as Damage, who would later go on to face and defeat him time and time again. He joined Lex Luthor's Secret Society of Supervillains and wound up getting nearly annihilated by shockwaves from the Liberty Bell while fighting"¦well"¦Liberty Belle.

He survived though, and lived just long enough to be IMMEDIATELY murdered by Superboy-Prime.
