The origin of Super Villians: Clayface
https://en.wikipedia.org/wiki/Clayface
Clayface is an alias used by several supervillains appearing in American comic books published by DC Comics. Most incarnations of the character possess clay-like bodies and shapeshifting abilities, and all of them have been depicted as adversaries of the superhero Batman. In 2009, Clayface was ranked as IGN's 73rd-greatest comic book villain of all time.[1]
A prominent enemy of Batman, Clayface has appeared in various forms of non-comics media, and has been voiced by Ron Perlman, Steve Harris, and Alan Tudyk among others, with a version of the character appearing on the television series Gotham, portrayed by Brian McManamon.
Publication history
Created by Bill Finger and Bob Kane, the original Clayface, Basil Karlo, appeared in Detective Comics #40 (June 1940) as a B-list actor who began a life of crime using the identity of a villain that he had portrayed in a horror film.[2] The character only appeared twice in the Golden Age, but was the inspiration for the shape-shifting Silver Age version.[3]
In the late 1950s, Batman began facing a series of science fiction-inspired foes, including Matt Hagen, a treasure hunter given vast shapeshifting powers and resiliency by exposure to a pool of radioactive protoplasm, who became the second Clayface. He retained the title for the next several decades of comic book history.[4]
