Two-Face (Harvey Dent) is a fictional supervillain appearing in American comic books published by DC Comics, commonly 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). As one of Batman's most enduring enemies, Two-Face belongs to the collective of adversaries that make up Batman's rogues gallery.
Once an upstanding Gotham City District Attorney, Harvey Dent was hideously scarred on the left side of his face after a mob boss threw acidic chemicals at him during a court trial. He subsequently went insane and adopted the "Two-Face" persona, becoming a criminal obsessed with duality and the conflict between good and evil. In later years, writers have portrayed Two-Face's obsession with chance and fate as the result of schizophrenia, bipolar disorder, and dissociative identity disorder. He obsessively makes all important decisions by flipping his former lucky charm, a two-headed coin which was damaged on one side by the acid as well. The modern version is established as having once been a personal friend and ally of James Gordon and Batman.The character has been featured in various media adaptations, such as feature films, television series and video games. For example, Two-Face has been voiced by Richard Moll in the DC animated universe, Troy Baker in the Batman: Arkham series, Billy Dee Williams in The Lego Batman Movie, and William Shatner in Batman vs. Two-Face. His live-action portrayals include Billy Dee Williams and Tommy Lee Jones in the Batman film series, Aaron Eckhart in The Dark Knight, and Nicholas D'Agosto in the television series Gotham. In 2009, Two-Face was ranked #12 on IGN's list of the Top 100 Comic Book Villains of All Time.
