Clayface

Basil Karlo was an actor who upon discovering that a remake of one of his classic horror movies was being made went insane and began killing the cast and crew, wearing the mask of the film's villain Clayface, until stopped by Batman. Initially having no superpowers, Karlo joined with a group of other "Clayfaces" and stole their combined powers, allowing him to shapeshift into any forms he wants.

Powers All Clayfaces possess the ability to shapeshift and change the form of their bodies. This gives them the power to look like any person they chose as well create weapons out of their limbs to attack enemy and also melt. More recent powers added to Clayface's mantle is the ability to melt objects by just looking at them and also being able to pass on powers to ordinary humans.

Because of Clayface's body nearly all physical attacks are useless. Clayface can also use his body to smother victims until lifeless.

Upon large usage of his shape-shifting abilities he can get dizzy and even faint, this means he can't be in a form for too long.
