An even darker Batman
Batman is the famous hero disguising himself as a bat to fight crime in the DC Comics universe. He can be found in many different versions, including the Dark Knight Heavy Metal comic book series that followed the Dark Knight Metal series. In the latter, Batman and the Justice League had discovered a dark multiverse hidden beneath the known multiverse, accessible by previously encountered strange metals. During his investigation, Batman had unwittingly released seven evil versions of himself from his multiverse controlled by the dark god Barbatos. Dark Knight directly follows the fight with the Batman who laughs, who released Perpetua from his cosmic prison. Batman, Superman and Wonder Woman continue to fight these creatures from the dark multiverse aided by the mysterious Quintessence.
