eventually defeated them both, and Fuller was put into custody. The "DC Rebirth" version of Sondra Fuller appeared in the Watchmen sequel Doomsday Clock, where she claims that Kobra was not the person who gave her the powers of shapeshifting after all. Instead, she claims that her powers were the result of a government conspiracy to create superpowered beings. Her proclamation further adds to the global scandal known as "the Supermen Theory", which suggests that the United States has been secretly creating superheroes and supervillains for an unknown/unstated purpose. Clayface later accompanied Black Adam in his attack on the White House.

Cassius finds it very painful and distressing to have pieces of himself taken, and will go to crazed lengths to recover them. When Thomas Elliot attempted to give himself the shapeshifting abilities of the Clayfaces, he determined that Cassius is the only 'pure' Clayface in existence, as all others retain fragments of their former human DNA where Cassius is the only
