Sonic the Hedgehog, known for his speed, has become the most famous person on Mobius! But after a battle with Eggman, the Blue Blur lost his speed! To get it back, he'll have to learn where he got it in the first place: being experimented on by Eggman with one of the Star Sapphires, gems that give one the ability to make the Master Emerald look like a paperweight, that he eventually lost 13 years ago. The Star Sapphires could only be triggered by one of a selfless and generous heart, and without his self-esteem, Sonic was neither. He, Tails, Amy and Knuckles must travel to the East of Mobius, where no one on Mobius has traveled before, while Eggman finally finds the gem he lost, enabling him the ability to conquer Mobius! Sonic and his friends will have to face a journey filled with deadly tasks, but will an arrogant Sonic be more difficult while Eggman wreaks havoc on Mobius in their absence?
