A once-famous character actor, Basil Karlo was enraged when one of his classic roles, in 'The Terror' was re-imagined by another actor. He disguised himself in a claylike mask and began to murder those involved in the remake of the classic film until his capture by Batman and Robin I. He has escaped from prison on a couple of occasions, and was last defeated by Batman, with help from the Looker, after he successfully duplicated the super-powers of Clayfaces III and IV.
