[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.
It all started when Sonic and his friends had a mission to stop Dr. Eggman from using the Chaos Emeralds to take over the world. Not only that, but he also kidnapped their friends. Cream, a 6-year-old rabbit, Cheese, her Chao, and Howl, a 16-year-old wolf.
Sonic, with the help of his buddy Tails, managed to stop Dr. Eggman, but the Chaos Control freaked out and teleported everybody through time and space.
Sonic ends up running into a 12-year-old human boy when he saved him from the adult pool in his backyard. (Since Sonic can't swim.)
After getting all of Sonic's friends together, except for a certain red echidna, they are on a mission to gather all of the chaos emeralds in order to get home. Dr. Eggman tries his best to stop them along the way.
Will they be able to succeed? Keep reading to find out!
