The Joker
DC Comics / Batman
The Joker has no confirmed origin — and that is precisely the point. He first appeared in Batman #1 in April 1940, created by Bob Kane, Bill Finger, and Jerry Robinson as a grinning killer whose chemical poison left victims with a permanent rictus smile. For decades he was a colorful nuisance. Then Alan Moore's Batman: The Killing Joke (1988) reframed him entirely. In Moore's story, he was once a failed stand-up comedian — a desperate man with a pregnant wife who agreed to help criminals rob a chemical plant and had one catastrophic bad day. He fell into a vat of chemicals, emerged with bleached skin and green hair, and broke. His central argument, tested on Commissioner Gordon through a night of psychological torture, is that any person can become him given sufficient misery. Batman refuses to accept the lesson. The Joker has never forgiven him. His most devastating storylines span decades of DC Comics history. In A Death in the Family (1988), readers voted by telephone to allow him to beat Robin — Jason Todd — to death with a crowbar. In No Man's Land (1999), he murdered Commissioner Gordon's wife. In Batman: Endgame (2014), he claimed immortality and nearly destroyed Gotham entirely. On screen, each actor has found a different truth in the character. Cesar Romero played him as a prankster in the 1966 television series. Jack Nicholson gave him operatic menace in Tim Burton's 1989 film. Heath Ledger's portrayal in The Dark Knight (2008) — a force of pure chaos who burns money, blows up hospitals, and tells a different story about his scars every time — won a posthumous Academy Award for Best Supporting Actor. Joaquin Phoenix's Joker (2019) depicted Arthur Fleck as a mentally ill man failed by every institution around him; the film won the Golden Lion at Venice and earned Phoenix the Academy Award for Best Actor.
