Distant Abyss Zone and Inhabitant

Dr. Eggman encounters an unknown creature in the Distant Abyss Zone.

The Distant Abyss Zone is an alternate Zone that exists in the same Multiverse as the Prime Zone. The first inhabitant of Sonic's World to visit it was Metal Sonic, who ended up there after traveling through a Genesis Portal from the Burning Ruin Zone that was closed behind him by Silver the Hedgehog. Dr. Eggman later traveled to this Zone via another Genesis Portal to recover him, only to encounter a monstrous creature that he battled using his Big Arm vehicle. After defeating it, he successfully recovered Metal Sonic and returned to their world. (SU: #75; StH: #276)
