Initially an actor in horror films, Karlo went mad when he learned a classic film of his was to be remade with a different actor as the lead role. He took on the mask of the film's villan, Clayface, and killed several of the remakes cast and crew before being stopped by Batman and Robin. Later, Karlo joined the Mud Pack, an alliance of shape-changing, mutated villans who had subsequently used the name Clayface. While that group was defeated, Karlo tricked his allies, injecting himself with the essences of several of them, becoming superhuman imbued with the abilities to change shape, melt others into protoplasm with a touch, and mimic the powers of heroes or villans he copies
