Background
After Darkseid and Doomsday failed to kill the heroes and steal one of the Foundation Elements, Grand Emperor Enoch decided to merge the two together into one as punishment for their failure, making sure they won't fail again, and resulting in the creation of Doomseid, an entity based mainly off Doomsday, but also adding Darkseid's power to Doomsday's body that could spell certain doom in the hearts of those who oppose him.
