Aaron Cash is a former security guard at Arkham Asylum.
One of the most senior and respected guards prior to the Joker's breakout, Cash was only afraid of one inmate: Killer Croc. Croc severely wounded Cash during a riot, forcing him to wear a hook on his left hand. However, Cash remained determined to keep Arkham's inmates under control and conquer his fear concerning Croc.
