Joker’s origin was told in Detective Comics #168 (February 1951), nearly a decade after the character’s debut. In this origin story, Joker is a laboratory worker who becomes the Red Hood (a masked criminal) to steal a million dollars from his employer and retire. He falls into a vat of chemical waste when his heist is thwarted by Batman, emerging with bleached white skin, red lips, green hair and a permanent grin.
The joker explains, “I was a lab worker, until I decided to steal $1,000,000 and retire! So I became The Red Hood! Finally, I reached my goal – by stealing from the Monarch Playing Card Company. My hood’s oxygen tube enabled me to escape by swimming under the surface of the pool of chemical wastes.” The joker didn’t realize the effects of the chemicals until he got home. He then decided to use his looks to his advantage and name himself the Joker after the playing card he most resembled.
