Several characters have worn the mantle of the villain Clayface in DC comics across eight decades – but the two most prominent must surely be Basil Karlo and Matt Hagen.
Karlo, the first Clayface, who debuted in June 1940, was a B-movie actor who had no superpowers but did have a thirst for blood and a penchant for crime. In the 1950s Batman adventures, Clayface reappeared in the shape of Matt Hagen, a treasure hunter whose accidental encounter with radioactive material gave him the power to transform into a lumbering mass of muddy goo with superhuman strength and the ability to shapeshift into any likeness.
