Sonic and Tails spot a strange glow off in the distance after landing the Winged Victory and decide to check it out. Coming across a dome of energy, Sonic deduces that it's a result of a weakened barrier between Mobius and another Zone caused by the Ultimate Annihilator. The pair is pulled into the dome and flung into a strange zone. Sonic thinks the zone is familiar and realizes where they are just as the two are blasted.
