Although the Death Egg is no more, Eggman has wasted no time in constructing an even more powerful space station, the Atomic Destroyer. Sonic knows the evil scientist is hiding somewhere in this massive maze with the final Chaos Emerald on hand, and it's a long and difficult road to reach the final confrontation. Along the way, Fang appears yet again but this time there seems to be an internal struggle as the bounty hunter tries to attack Metal Sonic but of course is no match. With Metal and Fang busy fighting each other, Sonic and Tails race through the innermost portions of the station, soon enough coming face-to-face with Eggman.
Eggman is beaten once again, however the day isn't won just yet. Metal Sonic goes rouge, and steals the seven Chaos Emeralds in a sneak attack. Using the doctor's latest copy technology, Metal creates the seven Dark Emeralds and transforms into a powerful new entity. Using the power of the Chaos Emeralds, Sonic achieves his own super form and the two Emerald-powered hedgehogs engage in the final showdown...
