Two-Face

Two-Face (Harvey Dent) is a fictional supervillain appearing in American comic books published by DC Comics as an adversary of the superhero Batman. The character was created by Bob Kane and Bill Finger, and first appeared in Detective Comics #66 (Aug. 1942). Two-Face is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.

Once an upstanding district attorney of Gotham City and an ally of Batman, Harvey Dent goes insane after a mob boss throws acid at him during a trial, hideously scarring the left side of his face. He adopts the "Two-Face" persona and becomes a criminal, choosing to bring about good or evil based upon the outcome of a coin flip. Originally, Two-Face was one of many gimmick-focused comic book villains, plotting crimes based around the number two, such as robbing Gotham Second National Bank at 2:00 on February 2 and stealing 2 million dollars.

In his autobiography, Batman creator Bob Kane claims to have been inspired by Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde, specifically the 1931 film version which he saw as a boy. Some inspiration was also derived from the Pulp magazine character the Black Bat whose origin story included having acid splashed in his face. In later years, writers have portrayed his obsession with duality and fate as the result of schizophrenia, bipolar disorder, and dissociative identity disorder. He obsessively makes all important decisions by flipping a two-headed coin, one side defaced. The modern version is established as having once been a personal friend and ally of Commissioner James Gordon and Batman.
