On one dark day, the planet wept as the World’s Greatest Super Hero fell. No one will ever forget the day that Superman died. Nor will they forget the name of the monster responsible—Doomsday. A creature whose rampage of destruction and violence could only be stopped when the Man of Steel made the ultimate sacrifice.

Doomsday was originally created on Krypton as part of a deranged scientist's quest to create the perfect hunter. The creature was subjected to cruel and terrible experiments—killed and cloned thousands upon thousands of times—a process that allowed his body to adapt natural defenses against whatever previously had bested him. Through this sort of rapid evolution, Doomsday became an unstoppable, nearly indestructible creature of violence and death that knew only hate and sought to kill everything in its path.

Doomsday possesses an immeasurable level of strength and invulnerability beyond those of even Superman. His disregard for life and endless rage make him an unpredictable and dangerous force, destruction itself let upon the world.
