Brainiac blocks out the sun in order to negate Superman's powers, and while he's growing weaker, Brainiac teams out up with Lex Luthor to create Doomsday, who eventually kills Superman. However, Superman's remains are recovered by The Eradicator who brings The Man of Steel back to life but without his powers with a black suit. They believe Brainiac will destroy Earth like he did to Krypton and they have to stop him. The Eradicator then replicates Superman's powers, synthetically. Long enough for Superman to fight Brainiac and Luthor until his powers eventually return naturally after being re-exposed to sunlight. The climax has the Superman and Brainiac fight in the skull as Brainiac downloaded himself into the body of a giant spider-like creature called "Thanagarian Snare Beast."
