The Mutant Leader is one of the primary villains in The Dark Knight returns by Frank Miller. He has appeared in a few animated adaptations of the comic.
History[]
The Mutant Leader was, as his title implies, the boss of the Mutant Gang.
After Batman attacked the gang at their headquarters, the Gotham City dump, in the Batmobile, the Mutant Leader called him a coward for using rubber bullets and for hiding in the Batmobile. This caused the Dark Knight to get out of the tank and fight the Mutant Leader, despite Alfred's protests. The Mutant brutally beat Batman, but just as he was about to kill him, Carrie Kelley, wearing a Robin outfit, provided a distraction, which was enough for Batman to subdue the brute. In prison, the mayor of Gotham tried to negotiate with the Mutant Leader, only to be murdered by him.
Later, following a plan conceived by Batman, Commissioner Gordon released him. Ending up near a sewer outlet, where his gang had assembled, the Leader is ambushed by Batman. Whereas during their first battle Batman tried to match the Leader physically, the second time he used his strategic mind to defeat him.
Following the Mutant Leader's defeat, the Mutant Gang split into several gangs, one of which was the Sons of Batman.
