Although this article is about an official minifigure, it never existed in physical form or appeared in any official LEGO sets.
Matt Hagen was a treasure hunter who discovered a pool of protoplasm. Upon bathing in the pit, he was transformed into Clayface and received shape-shifting powers. Hagen could transform his body into any form. Hagen used his powers for crime and had to return to the pit frequently to retain them.
Clayface's head is combined to a sandwich plate to help give the appearance that he is somewhat of a blob. His face is coloured orange, like the rest of his body, has two, white squinting eyes, an opened, black mouth with a row of white teeth on the bottom, and several areas with his clay-like protoplasm in compacted together to give him shape, like above his eyes where it forms a brow. Clayface's body also uses the design to give his body shape and blends right into the blank orange torso. Clayface's arms, hands, and legs are also orange.
