Catman is a supervillain that uses cat-themed weapons. In "Legends of the Dark Mite!", he tries to sell an endangered Sumatran Tiger to the highest bidding poacher, animal collector, and chef. Catman was then attacked by Batman. The poacher, collectors, and chefs end up fighting Batman. Catman released the Sumatran Tiger to attack Batman only for it to fight Ace the Bat-Hound. After the Sumatran Tiger was defeated, Catman was cornered up a tree and begged Batman to call him off. Catman was then sent to Blackgate Prison. He later appeared as an illusion in Bat-Mite's fantasy alongside the other Batman villains. Bat-Mite defeated him by turning him into a cat.
