History

It seems that he wants revenge aswell as Batman's cowell as his thirtenth hat. He traps the caped crusader in clay but he escapes. Batman and Robin confront him but Jervis straps them to a hat machine which will cut them open. They escape and defeat him. He is presumably sent back to prison (BM: The Thirteenth Hat and Batman Stands Pat)

He escaped from prison again in an attempt to steal Batman's cowell once more. (BM: The Contaminated Cowl and The Mad Hatter Runs Afoul)
