A scientist studying Clayface (05 - Cassius) was attacked by a "sample" taken from the child. The doctor was overtaken by the clay entity, giving him the ability to melt things from a distance. It headed toward Gotham City to find its parents. D.E.O. (Department of Extra-normal Operations) agent Cameron Chase was assigned to "Clay-Thing." Batman got to her at the cave where he was born and learned what she knew. They confronted it at Arkham Asylum. Clay-Thing liquidized before them.
