remarking that Croc "has a certain... eccentric way with evidence". Croc is shown leading a gang of thugs, and later becomes a high-level member of Joker's newly formed gang. This vision of the character is not unlike the one from Azzarello's previous work on Batman, Broken City. In the Batman Beyond comic, Killer Croc is mentioned as being a prisoner in a Cadmus Labs facility; his cell is briefly attacked by the new Hush, a clone of Dick Grayson, when Hush escapes the facility before he decides to simply leave. Another Cadmus official later contemplates releasing Croc to lure Hush out, but Amanda Waller dismisses the idea, due to the potential for collateral damage. In the crossover Batman/Aliens 2, Killer Croc is part of an experiment by the twisted black ops officer Doctor Fortune to create hybrid soldiers using DNA from the Xenomorphs and the DNA of some of Batman's villains, hoping to harness the villains' genetic traits for survival without their psychological trauma. However, her use of Croc proves to be her undoing, as Batman notes that Croc turned to villainy because he was naturally ruthless, rather than being subject to any sort of trauma, resulting in the Croc/Xenomorph hybrid tearing Fortune's head off before Batman manages to drown it after destroying her offshore base. In Batman: Crimson Mist, Killer Croc begins as a rumored serial killer stalking Gotham's sewers, later joining Two-Face's gang as the muscle. Faced with the threat of the vampire Batman stalking and killing his opponents, Killer Croc and Two-Face form an alliance with Commissioner Gordon and Alfred Pennyworth to trap Batman in the Batcave and expose him to the sunlight (although Croc briefly contemplated just physically tearing Batman apart himself before the others pointed out that he was too fast for Croc, the vampire Batman proving more than a match for him physically when they did engage in close-quarter combat, despite his withered physical condition). Although Croc and Two-Face attempt to kill Gordon and Alfred when Batman is believed dead, Alfred is able to help his old master recover by sacrificing his life and blood to give Batman the strength to stop Gotham's last criminals. With Alfred's sacrifice, Batman impales Croc with a stalactite, commenting that Croc can keep his cold blood, thanks to Alfred's sacrifice having sated his appetite for the moment. In the alternate timeline of the 2011 "Flashpoint" storyline, Killer Croc
