Lex Luthor II is desiring to prove that the four pretenders to the name Superman are all liars when the LexSat communications satellite picks up an enormous spacecraft approaching Earth, with telemetry suggesting that it's heading toward Coast City. Meanwhile, the Last Son of Krypton is in Coast City helping to put out a fire at Ferris Aircraft when he hears the warning of the spacecraft coming and decides to stay and help. White House security contacts Cyborg Superman of the same situation and decides to head to Coast City to deal with it. As the enormous ship hovers over Coast City, it launches loads of carnage globes all over. The Last Son of Krypton is puzzled over their appearance and decides to investigate the ship that's dropping them, but the Cyborg Superman blasts him away, saying he will be blamed for the destruction of Coast City. Soon the carnage globes ignite, releasing a firestorm that consumes the entire city and reduces the Last Son Of Krypton to a nearly powerless humanoid form of energy. Over the crater that was Coast City, the ship launches mechanical "seeds" that burrow into the ground and build a new "city" in its place. The Cyborg Superman hides what he sees from White House security by saying that there's nothing left in the place where Coast City was and rendezvous with the captain of the ship, who turns out to be Mongul, kneeling before him and kissing his hand. Cyborg Superman says that Metropolis will be next.
