HISTORY

Quite who the Joker was before the accident that transformed a common crook into a hideous parodic image of a circus clown has never been conclusively established. What is known about him is that he is an extremely dangerous homicidal maniac who may at times seem silly but is almost always in a murderous mood. The extent of his evil actions is best summed up in three of his actions: crippling Barbara Gordon; killing the second boy to bear the name of Robin; and holding New York City to ransom in a nuclear missile attack. The latter action got him incarcerated in the ultra-high security prison the Slab, which won't be anywhere near as escapable as Arkham Asylum for the criminally insane, from which he often burst out to match wits with the Batman.
