Doomsday is a Krypton weapon created for combat and destruction from the DNA from multiple species. When it arrives on earth it takes the human form of Davis Bloome in order to survive without detection. As Davis, he had little control over Doomsday and it turned him into a killer.
It is eventually separated from Davis, who becomes a killer again, and is killed. Doomsday is defeated by Clark and buried deep underground to prevent it from getting sunlight, hoping it would stop the creature. In the 31st century after regaining sunlight, and being unleashed on the Kryptonian's it comes back stronger than ever.
