Joker

the Joker is a villain in the DC Universe and the archenemy of Batman.

Origin
The true origin of the Joker has always been shrouded in mystery. What is known was that he fell into a vat of chemicals while fleeing the police, and upon his escape, discovered that the chemicals bleached his skin white, dyed his hair green, and stained his lips red. A common belief is that he was a criminal called the Red Hood who attempted to steal from the Ace Chemical Plant, where he worked as a chemist. When Batman and the police arrived on the scene, the Hood had no choice but to dive into a chemical vat and swim out a pipe in the vat. The mere sight of the disfigurement the chemicals had done to his body, coupled with the deaths of his wife and unborn son, drove him insane. Thus, the Joker was born, terrorizing Gotham City with his flamboyant crimes and his unique mass murders.

Powers
Joker has no powers, but is a master of hand to hand combat and a skilled chemsit.
