[A rebooted version of the anime, Sonic X. Obviously Enough.]
On an unnamed world, Sonic the Hedgehog, Miles "Tails" Prower, and Amy Rose attempt to rescue Cream the Rabbit and her pet Chao; Cheese, from the mad scientist Doctor Eggman, who has already retrieved the seven Chaos Emeralds. While attempting to destroy his base, one of Eggman's robots inadvertently shoots a machine containing the Emeralds, which activates the "Chaos Control" technique.
This teleports Sonic, Eggman (and his robots), Tails, Amy, Cream, and Cheese, as well as Big the Cat (with his pet frog Froggy), Rouge the Bat, Knuckles the Echidna, and the Chaotix (a detective crew comprising Vector the Crocodile, Espio the Chameleon, and Charmy Bee) to Earth, the parallel-universe version of their world with humans.
Running is what you love in Mobius, but a trail of the cold leaving your fingertips is what you love more.
But when helping Sonic and his friends to bring back the Chaos Emeralds, stolen by Eggman, and save Cream and Cheese, you and your friends magically end up in a world that was not your own.
And with the Chaos Emeralds scattered across this unknown world, a 12-year-old boy named Chris, helps you and Sonic stop the evil doctor from getting his hands on all seven of the Chaos Emeralds.
