Synopsis
Set in a world where Doctor Eggman has conquered the world, a brave yet occasionally reckless hedgehog known as Sonic joins the Freedom Fighters to take down Eggman and other threats.

Main

 * The Freedom Fighters. A group of heroic Mobians who oppose Eggman's empire, consisting of:
 * Sonic the Hedgehog - A brave blue hedgehog who can run in superhuman speeds as he becomes a member of the Freedom Fighters in a race to stop Eggman.
 * Miles "Tails" Prower - Sonic's best friend, and a young twin-tailed fox who can fly by spinning his Tails, and is a mechanical genius, having built several tools for the Freedom Fighters.
 * Sally Acorn - A serious, but kind-hearted female chipmunk who is the leader of the Freedom Fighters, Sonic's love interest, and Tails's caring adoptive sister who is a skilled fighter and scientific genius. Along with use of high-tech (including energy boots which allow her to match Sonic's speed, and Ring Blades attached to her arms), Sally also possesses a Chaos Gem in her necklace which allows her to create astral projections.
 * Amy Rose - Sonic's cousin, and a pink hedgehog who wields a red and gold hammer pulsing with Chaos energy. She has a slightly obsessive crush on several people including Knuckles and Shadow.
 * Knuckles the Echidna - A short-tempered, yet noble red echidna with superhuman strength and spiked fists. He is the guardian of the Master Emerald in Angel Island as he befriends Sonic and surprisingly joins the Freedom Fighters.
 * Bunnie the Rabbit/Bunny Rabbot - A goofy, but friendly rabbit who has been partially roboticized by Robotnik as she joins the Freedom Fighters, heading to fight against his androids.
 * Antoine D'Coolette - A rather cocky coyote swordsman who has trained under an ancient order of knights known as the Gilded Blades as he soon joins the Freedom Fighters having both a friendly rivalry with Sonic and a crush on Bunnie.
 * Nicole the Holo-Lynx - Sally's A.I. assistant, best friend and surrogate sister. Initially a artificial intelligence entity without any form, Nicole evolves thanks to the energies of a Chaos Ring, allowing her to take on the physical form of a Mobian female lynx.
 * Rotor the Walrus - A member of the Freedom Fighters who is also a mechanical genius, known for being quite stoic and unable to express himself properly, being seen as aloof.
