Two-Face is a DC Comics supervillain, an enemy of Batman. Created by Bill Finger and Bob Kane, he first appeared in Detective Comics #66 (August 1942). Inspired by Robert Louis Stevenson's novel The Strange Case of Dr. Jekyll and Mr. Hyde, Two-Face was once Harvey Dent, District Attorney of Gotham City and close ally of Batman. After a criminal disfigured half of his face with acid, Dent became the insane crime boss Two-Face.
He obsessively makes all important decisions by flipping a two-headed coin, one side of which is scratched. While Dent claims his Two-Face persona is a result of his disfigurement, his face has been restored several times, only to be damaged once again by his own doing.
