The Joker is a character created by Bob Kane, Bill Finger and Jerry Robinson. He was a normal man until he accidentally fell into a vat of chemicals. The chemicals mutated him, turning his skin white, his lips red and his hair green. This drove him to insanity, and he become the supervillain known as the Joker, dedicated to spread chaos and destruction across the world. He is Batman's arch-nemesis.
