Brainiac sends Doomsday to kill Superman, as well as blocking out the sun to make Superman powerless, as Superman is fueled by sunlight. Brainiac teams up with Lex Luthor, but Superman is resurrected by a Kryptonian robot, the Eradicator. Brainiac wishes to possess the Eradicator and its technology. Powerless, the resurrected Superman is sheathed in a robotic suit formed from the Eradicator itself until his powers return, courtesy of sunbeams, and defeats Brainiac.
