Amphibius seemingly had a similar history as his Earth-616 counterpart. He was among those native to the Savage Land assembled by Magneto that he experimented on and gave powers to. The group became known as the Savage Land Mutates.
Savaged[]
The Savage Land Mutates were taken over by
Tyrax, who used them to recreate and prefect Magneto's equipment as well as guard
Arcadia. Once the Mutagenic Machine was completed, Tyrax used it on
dinosaurs to create
Dinosauroids. The Savage Land Mutates came in conflict with
Badrock,
Kar-Zar,
Wolverine, and
Zabu. The four stormed Arcadia and defeated the Savage Land Mutates and reverted the Dinosauroids. During the battle, Tyrax escaped. Afterwards, Kar-Zar exiled the Savage Land Mutates from the Savage Land.
