Matt Hagan was an actor. He was known as the man with a thousand faces. But eventually, for reasons unknown, his career was cut short. He largely disappeared from the public eye, only being seen a handful of times each year. To the majority, it was like he had just disappeared altogether, forgotten to time. Now it is time for his reemergence. But now, he is not Matt Hagan. He is the shapeshifting monster, Clayface. 

Matt Hagen/Clayface appear in two episodes in one scene each.
