Attempting to flee from the clones with Doomsday, the Superman Family discovered that their ship was on course for Earth with the potential to trigger an extinction-level event if it were to strike. Their attempt to divert the ship was interrupted by a being called "Doomslayer", who resembled a cyborg version of Doomsday and was later revealed to be a Doomsday who was tossed down an infinite tube that gave it time to evolve. Doomslayer effortlessly tore Eradicator apart and proclaimed that Earth must die for the future.
