Doomsday src
Doomsday is an ancient Kryptonian monster with the ability to quickly adapt to its surrounding.

Living only to kill, Doomsday came to Earth and quickly made itself an enemy of Superman.

Fives Years of Superman's Regime

Doomsday, having been held in captivity for the five years of Superman's regime after the fall of Metropolis, was personally taken prisoner by Superman. The dictator attempted to re-educate the monster through means of the Phantom Zone, but the methods were ineffective. Instead, Kal used mind control technology, which proved much more successful. Doomsday, the creature that knew only how to kill, was now forced to work as Superman's bodyguard.

After Superman killed Lex Luthor and Shazam, he instructed the Flash and Yellow Lantern to "get Doomsday ready" for the impending attack on Metropolis and Gotham. When an alternate-reality Superman arrived to fight the Regime, Doomsday was summoned to combat him but was defeated and thrown into the Phantom Zone.[1]

Doomsday IGAU Epilogue 0001

Free of Superman's control, Doomsday eradicated the remaining meta-humans. He then manipulated technology in the abandoned Fortress of Solitude to terraform the Earth. It soon resembled prehistoric Krypton. At last, it felt like home.

After a few years of exterminating humanity at his leisure, however, Doomsday needed a challenge. Having assimilated Superman's ability to fly, he headed for a nearby space sector. He had heard rumors of an opponent worthy of his attention: a Czarnian mercenary with a taste for violence. Doomsday was eager to meet this "Lobo" in battle.
