In S.T.A.R. Labs, Superman's allies used the original Doomsday's body to try to find a way to stop the Doomsday clones. Doomsday awakened, but Eradicator (who was thought to be killed by Doomslayer) was in control. As Eradicator and the heroes attacked the Doomsday clones, he warned that Doomsday's mind was beginning to awaken. In the final battle, a weakened Superman made contact with the ship's artificial intelligence before it reached Earth's core, hoping to have the tower teleport away. Meanwhile, the Doomsday clones were defeated by Earth's heroes and sent back into the pit in which the tower was located. Eradicator arrived and defended Superman, now very weak, from Doomslayer, quickly throwing Superman out of the tower and allowing himself to be trapped with Doomslayer before the tower teleported away.
