Widely considered Batman's arch-nemesis, the Joker has also been responsible for numerous tragedies in Batman's life, including the paralysis of Barbara Gordon and the death of Jason Todd, the second Robin. In recent years, the character has taken on the persona of an evil-incarnate, simply taking joy in tormenting Batman or trying to push him into villainy. Falling into obscurity by the 1960s, he was re-introduced in the 1970s as a more legitimate threat and one of the most infamous criminals within Gotham City. By the late 1940s, Joker had been reimagined as a harmless prankster. Initially intended to serve as a one-time appearances, Joker's instant popularity ensured that the character would continue to appear, becoming a frequent enemy of the Dark Knight and Robin, the Boy Wonder. First introduced in Batman #1 (Spring 1940), he was originally a criminal mastermind with a devious sense of humor. The Joker is a supervillain and the archenemy of Batman.
