Born on the planet Krypton during a time when only the strongest creatures could survive, Doomsday was the result of a rapid natural selection process bred to hate all life. Doomsday's body is covered with vicious bony spurs that can render even Superman's skin. His endurance makes him almost impossible to kill. He is the epitome of villainous power and strength. With the ability to regenerate after every battle, Doomsday becomes bigger and stronger; therefore no opponent of his has ever defeated him twice.
