A Little History
Before there were Kryptonian’s there was Doomsday. Doomsday was the work of an alien group of engineers. They set out to create a monster that the galaxy had never seen before. Bertron, the alien responsible for the work, took an infant and had it survive on its own on the unforgiving Kryptonian landscape.
The infant, of course, did not and could not survive the harsh realities of Krypton. Bertron was unfazed and expected these results. Each time the infant perished, he reanimated the infant through an intense cloning process. This process was repeated for many years, and each time the creature died, it adapted to that form of death. In short, it learned from how it had died, and adapted so that it would never die that way again.
As time passed, the power of the creature grew. It grew so much that it turned its attention to its creator and destroyed the lab he was conceived in. Bertran was unable to escape the path of destruction and while he laid on his floor breathing his last breathes, he remarked that he had finally succeeded in creating a lifeform that the galaxy would fear.
When the supply ship arrived to restock the lab, Doomsday took control of it and made his way into space. It was here that he truly began his reign of terror on the planets.
