Born from the nightmares of the Dark Multiverse, The Batman Who Laughs is a hybrid version of the Batman and The Joker from Earth -22. This twisted version of Batman was created when nanotoxins from The Joker’s heart were released into Bruce Wayne’s bloodstream, causing the Dark Knight’s perfect mind to merge with the warped psyche of the Clown Prince of Crime. He soon became part of an attempt to plunge the entire Multiverse into ultraviolence, chaos, and utter darkness.
Hailing from Earth -22, these young boys were infected by the absolutely nightmarish Batman Who Laughs to become his own band of twisted Robins. Kept on a chain-link leash, these sinister sidekicks follow the evil Dark Knight’s bidding, fighting tooth and claw to take down any enemy.
