Joker

Joker (Unknown) is a DC Comics character from Prime Earth, first appearing in Detective Comics Vol 2 1, created by Jerry Robinson; Bill Finger; Bob Kane.

The Joker is a supervillain published by DC Comics and the definitive archenemy of Batman, introduced in 1940 by Jerry Robinson, Bill Finger, and Bob Kane. Styled as the "Clown Prince of Crime," he is a homicidal criminal whose clown-white skin, green hair, and rictus grin have made him one of the most recognizable villains in fiction. His true name and history remain deliberately unverified, and he is widely regarded as the chaotic thematic opposite of Batman's order and self-control.

The Joker has no superhuman powers, relying instead on a brilliant if unstable criminal mind, expertise in chemistry and toxins, and an extraordinary talent for manipulation and long-term planning. His signature weapon is Joker venom, a toxin that leaves victims laughing and locked in a deathly grin, supplemented by acid-spraying flowers, razor-sharp playing cards, joy buzzers, and an oversized handgun. His unpredictability and apparent indifference to pain or death make him unusually difficult to anticipate or contain.

The most commonly cited origin depicts a failed comedian coerced into a robbery at a chemical plant as the criminal Red Hood, who falls into a vat of chemicals that bleaches his skin and shatters his sanity, though the Joker himself insists his past changes with the telling. Over the decades he has driven much of Batman's mythology, crippling Barbara Gordon, killing the second Robin, and terrorizing Gotham through schemes such as citywide gas attacks and elaborate psychological traps. Modern arcs have explored his obsession with Batman as a necessary counterpart, his brief stint as Arkham orderly "Eric Border," and his repeated returns from apparent death.

Some versions of his backstory include a pregnant wife, Jeannie, whose death precedes his transformation, along with an unnamed mother and a son, Jeremy; the vigilante Lonnie Machin has been suggested as another possible son. His most enduring relationship is with Harley Quinn, the psychiatrist-turned-accomplice he manipulated and abused before she eventually broke away. Above all, his defining bond is his fixation on Batman, an obsessive rivalry he treats as the central relationship of his life.

The Joker generally works alone or with expendable henchmen, but he has led the Red Hood Gang, organized his own Joker Incorporated, and joined villain coalitions including the Legion of Doom and the League of Villainy. He has also been a recurring member of Injustice League-style alliances, though his unreliability makes him a liability to any organized group.

Among his many aliases are Red Hood, Jack Napier, the Pale Man, the Comedian, and Pagliacci, while his legal name has never been definitively established in mainstream continuity. He is central to landmark stories such as The Killing Joke, The Dark Knight Returns, and A Death in the Family, and has been portrayed on screen by Cesar Romero, Jack Nicholson, Mark Hamill in voice work, Heath Ledger, and Joaquin Phoenix. Ledger and Phoenix both won Academy Awards for their performances, a rare distinction for a comic book role.
