Joker

The Joker is a supervillain published by DC Comics. A sadistic criminal mastermind, he is the archenemy of Batman. Created by Bill Finger, Bob Kane, and Jerry Robinson in Batman #1 (April 25, 1940), the Joker would endure to be one of the most iconic characters from the DC library, often listed among the greatest comic book villains and fictional characters ever created. His origin is ambiguous, with the Joker himself admitting that he prefers his origin story to be multiple-choice. What is apparently true is that he was once a failed comedian who fell into a tank of chemical waste that bleaches his skin white and turns his hair green and lips bright red; the resulting disfigurement drove him insane. The Joker's chaotic insanity often results in partnerships with other supervillains being temporary and volatile. The Joker has appeared in various media, merchandise and even theme park rides.
