Batman: The Revenge of ClayfaceLibrary Binding, 1 January 2009

Billionaire BRUCE WAYNE is asked to support the military's newest weapon, the ParaBomb X, a high-tech orb that emits a paralyzing light. But during the weapon's demonstration, a general grabs the orb, crashes through the window, and falls to the street below. BRUCE WAYNE is stunned. When he looks down at the street, he sees the thief turn into a gooey pile of mud and slip down a storm drain with the stolen weapon. He wasn't a general at all, he was one of BATMAN'S strangest enemies, CLAYFACE.
