Powered by the energy of the 5th dimensional being, Superdoom attacked Superman, with growing strengh. However shorty after the defeat of his master, Superdoom triggered a self destruction system. Superman could put him in a safe distance where he blow up, without any further damage to anyone.

During Multiversity he appeared to have been revived and fought alongside the other heroes of the Multiverse against The Gentry.
