After being defeated by Perfect Chaos, Sonic loses the Chaos Emeralds and Perfect Chaos sent him flying into the air by spitting him out of his mouth, when trying to devour him, but Tails saved him in the Tornado. Then Dr. Eggman finds them in Chaos when Chaos leaves his Perfect form. Then Eggman takes the Chaos Emeralds to his most fearful robot, Metal Sonic, which is a robot that is supposed to be better than Sonic in every way possible. So now that Sonic is powerless, Dr. Eggman makes Eggman land and everything is madness. Sonic then has to stop Eggman and collect the Chaos Emeralds not only to defeat Eggman, but return Mobius back to it's peaceful form.
