Mister Zsasz is a Gotham City serial killer who acts as a recurring villain to Batman. His body is covered in self-inflicted scars shaped like tally marks, one for every murder he's committed. Originally a business entrepreneur, after a series of deep personal tragedies he was driven to madness and became obsessed with nihilism, killing anyone he met to relieve them of the burden of their lives. Because of this he regularly resides in Arkham Asylum. He has been a member of the Secret Society of Super-Villains.
Zsasz was created by Alan Grant and Norm Breyfogle, first appearing in Batman: Shadow of the Bat #1. (1992)
