Two-Face
Harvey Dent was a bright and upstanding district attorney of Gotham City, dedicated to ridding its streets of crime and corruption. But after mob boss Sal Maroni threw acidic chemicals at him during a court trial, he was hideously scarred on the left side of his face and went insane. He adopted the "Two-Face" persona, becoming a criminal obsessed with the number two, the concept of duality, and the conflict between good and evil. He makes all important decisions by flipping a two-headed coin, with the other half scarred, given to him by his father.
