- "Let me tell you a story. A bat saves a scorpion from drowning in a river. But as the bat carries him out of the churning, deadly water, the scorpion stings the bat! In terrible agony, the bat asks 'Why?! I tried to save you, now we'll both die!' And the scorpion says 'That's the point, sucker!' HAHAHAHA! Oh, I love that story. Cracks me up every time." —Joker
The Joker is Batman's antithesis, a force of fear and chaos against Batman's fight for safety and order. His weapons include Joker toxin, pistols, nuclear warheads, various joke props and gags, and a sick enjoyment of pain and fear. The Clown Prince of Crime is a warped psychopath who inspires chaos.
Despite multiple incarcerations in the infamous Arkham Asylum, he remains gleefully insane - and determined to torment Batman by any means possible. The Joker has belonged to many criminal organizations, but his fellow villains fear him almost as much as Gotham City does. He is unpredictable, manic, bloodthirsty, and capable of twisting even the sanest minds to his warped plans.
The story of his origins are relatively unknown. One of the more reliable origins describe that the man-who-would-be-the-Joker was a lab assistant for Ace Chemicals who had a dream of working as a stand-up comedian, however, after quitting his job and taking a shot at his dream, he wasn't very successful and suffered low self-esteem and self-worth issues because of this.
Married to a loving wife named Jeannie, the pair were expecting their first child. To get money for his family the-man-who-would-be-the-Joker becomes involved with the criminal gang the "Red Hoods", and agrees to help them into the Ace Chemical plant to rob them.
Donning a black tuxedo and red helmet, the same as the other gang members, the-man-who-would-be-the-Joker finds out that his wife had died as she was testing a baby-bottle heater on the eve of the robbery, however, he was forced to continue the robbery. As the gang encounters the Batman, who has come to thwart the robbery, the-man-who-would-be-the-Joker becomes terrified of the Batman's appearance and jumps/falls into a vat of chemicals while escaping.
While surviving the plunge and chemical exposure, he goes mad seeing his disfigured face on top of losing his wife and family, and starts to perceive life as one black, awful joke.
Taking the name "The Joker", the man lost all sense of remorse or perceived sanity, instead only acting upon his own whims in a world where nothing is more than a cruel joke.
Possessing no notable M.O., the Joker might one time perform an overly complex heist and the next embark on a purely homicidal spree; sometimes for money, sometimes for revenge, sometimes for fun and sometimes just for the pure hell of it. Over time, however, the Joker's "games" got rougher, with higher stakes and a darker sense of humor.
Beginning to reason that he and the Batman were two sides of the same coin, it was at that point that what was considered his crime career ended and his personal goal to drive the Batman insane began.
Starting with James Gordon, the Joker attempted to break the commissioner by invading his home, paralyzing his daughter and subjecting him to torture. However, Gordon was saved by the Batman, who attempted one last time to find a truce between them but failed.
Next was Jason Todd, the second Robin, whom the Joker beat to death with a crowbar before leaving him with his biological mother to die in a building explosion. The Batman was too late to save them.
Dangerously unpredictable and certifiably insane, the Joker is just as likely to work as a reliable team-mate as to back stab everyone for no apparent reason.
He also has a romantic relationship with his girlfriend Harley Quinn (Harleen Quinzel).
