Sonic★the★Hedgehog

Sonic and Tails are enjoying a carefree life on South Island when Dr. Eggman claims that a sabotaged generator in the Land of Darkness will soon destroy Planet Freedom. Suspicious but unwilling to risk their home, the pair race into enemy territory to stop the disaster.

The mission is a trap. Eggman uses Sonic's data to create Hyper Metal Sonic, a mechanical rival capable of matching his speed, memories, and instincts. With the planet itself in danger, Sonic must face an opponent who knows him almost as well as he knows himself.
