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. Now he is thrust into the world of Mortal Kombat, where he will fight for supremacy against all Kombatants.
