Joker is the main antagonist of Batman: Arkham Origins and Batman: Arkham Asylum and the secondary antagonist of Batman: Arkham City and Batman: Arkham Knight. He is an insanely homicidal supervillain and the arch-nemesis of Batman. His bleached white skin, green hair and blood red lips belied the chaotic nature that underlay his cartoonish appearance. The extremely intelligent, self-styled Clown Prince of Crime had no superpowers beyond for incredible violence and a skill at creating deadly mayhem. He frequently concoted elaborate schemes to entrap his nemesis.
