After defeating Dr. Eggman and rescuing his friends, Sonic is finally enjoying some peace and quiet in Cryptic Coast. But when his mysterious cloning machine arrives at his doorstep, Sonic can't resist testing it out.
What starts as a harmless prank quickly spirals out of control when Sonic's clone develops plans of his own.
Convinced that he is the one true Sonic, the rogue clone traps Sonic, Tails, and Knuckles in a series of bizarre challenges across strange worlds, floating fortresses, lava-filled wastelands, and mysterious portal dimensions. As the clone's obsession grows, Sonic must race to stop him before he takes over Sonic's life for good.
Facing deadly obstacles, dangerous Badnik armies, giant robotic machines, and some of the strangest places they've ever visited, Sonic and his friends will need all their speed, skill, and teamwork to make it home.
But one question remains...
If there can only be one Sonic, who will everyone believe is the real one?
The fastest hero on Earth is about to face his greatest rival... himself!
