Doomsday

Summary
Doomsday was created on a prehistoric Krypton thousands of years ago by a scientist named Bertron as a bio-mechanical super-soldier and living weapon of mass destruction.

This process involved Bertron cross-breeding the artificial birth of a Kryptonian hybrid, left to fend for itself in the more harshest environments of the Kryptonian wilderness with creature killed and its genetic material collected to create a more resilient clone. This process, along with a further cross-breeding with the DNA of the strongest creatures on Krypton, was repeated over and over for decades as a form of accelerated natural evolution.

The agony of these repeated deaths was recorded in the genes of Bertron's final creation, driving the creature insane and to follow one overwhelming instinct: destroy everyone and everything in sight. When the creature proved too difficult to control, the Council discontinued Bertron's experiments and banned all forms of cross-breeding while having the creature jettisoned into the Phantom Zone. However, the beast acted in his final moments of consciousness to change the stasis cell's trajectory and it eventually crashed on Earth, the force of the impact driving it deep underground.

The beast slept for centuries before finally reviving and bursting free. Dubbed "Doomsday" by Booster Gold, the beast is still motivated by his instincts to kill everything around him yet has a greater obsession to kill all Kryptonians.
