Clayface

Actor once called "The Man of a million faces"
Disfigured in a terrible car accident, became a test subject Renuyu;
Allowed him to physically reshape his face to any face he desired
Effects were temporary & addictive, forced to do criminal activities for more Renuyu
Eventually refused to cooperate, pushed into a vat of Renuy;
Overdose saturated every cell in his’ body, turned into bulky & misshapen clay-like form
Body dissolved in saltwater, restored by waste chemicals
