I saw the thread here about favorite heros, and a few entries didn't fit because they were bad guys. So who is your favorite evil person of all time?
My favorite would probably be Blackheart. Not from the movie "Ghost Rider", the one from the comics. 15 foot tall black demon that fought by throwing lost souls at you. Can't quite get cooler than that. Plus, in "Marvel vs. Capcom 2", Blackheart can launch a barrage of demon piggies on the enemy.
