The Unkillable Doomsday?

Doomsday. A perfect war monster created from Kryptonian genes, it existed solely to hunt Kryptonians. Apokolips had merely acquired a small amount of Doomsday's genetic material and added it to Parademon cultivation, yet it had enhanced the Parademon soldiers by more than tenfold! Eight years ago, while Xi Nian and Gwen had been drawn into the Battle of New York, Superman had perished together with Doomsday right here in present-day Metropolis! Later, to commemorate Superman, the local city had specially built this Superman Plaza.
