Bio: Once under the private collection of Morgan Edge, Clayface
was sealed away in bio-hazard containers, under lock and key. In an
attempt to get their team strengthened by the shape-shifting behemoth,
Clayface was freed by the Secret Society. Feeling guilty otherwise, he
agreed and together they attempted to take the League down.
During one of their battles, Clayface was frozen, while J'onn J'onzz, in
Clayface's form, was posed as Clayface. He was later un-frozen when the
League began to attack one another in a football stadium, with an
audience well in the thousands. The Justice League prevailed and
Clayface was taken down.
