The Mutant Leader was a gang leader from a story told by Carrie.
The Mutant Leader, as his name implied, led a vast battalion of mutant punks bent upon taking over Gotham City, and wiping out all humans who stood in their way. Batman, however, planned to stop the operation, showing up in one of the group's many riots. Aided by Robin, the two managed to bring down the Leader, only after the Dark Knight battled with him in a mud pit, breaking his leg.
