Bio: This blue hedgehog can move faster than the eye can detect. Somewhat leader of the three, he is often the one who is taking the initiative to get into action, rushing into things and sometimes messing things up. He plays a unique 3 necked guitar.

Bio: Sonic and Manic's sister, and the brains of the operation. She grew up in a more upper class family and got a better education, as well as karate lessons. She operates a sweet crotch rocket motorcycle, a laser shooting keyboard, and can tornado spin like Sonic can.

Bio: Manic puts the punk in punk rock. This sibling grew up in the sewers with a band of theives. He is a bit rough around the edges when it comes to proper ediquate, but he's a kind hearted kid with a drum solo that will leave anyone shaking.

Bio: The mother of Sonic, Manic, and Sonia. Queen Aleena is the rightful ruler of Mobius, but was overthrown by Robotnik. She often is in the background, keeping an eye on her children in the shadows, and guiding them to fullfil their destiny.

Bio: This Oracle boasts some pretty nifty magic power, but does not get invovled in the fight. He is the one who predicted that Sonic, Sonia, Manic, and thier mother would someday reunite and make the councel of four, and overthrow Robotnik. Sometimes he gathers the siblings and sends them to a far off place to test their courage and strength to further their abilities.

Bio: This long haired "hippy" looking mouse is no tree hugger. Although not a big combator in the Freedom fight, Trevor is trained enough to help out where he can and to take the risks needed.

Bio: Cyrus is to SU as Rotor is to SatAM. Cyrus is the freedom fighter's mechanical whiz, providing Sonic and his siblings with new devices to help in the freedom fight.

Bio: Knuckle's first appearance in a cartoon series, this Echidna is a friend of the Queen, and protects Angel Island. He is first discovered when Sleet and Dingo try to take the master emerald that keeps the island afloat.

Bio: Sonia's ex-fiancee. This aristrocrat pays taxes as with all the aristrocrats, and tries to stay out of trouble. A bit of a coward, and also thinks fighting is distasteful, he is often on the bad side of Sonia. Sometimes he's in the way, sometimes he helpful.

Bio: This guy doesn't get it. Robotnik has overthrown the rightful ruler of Mobius, Queen Aleena, and has roboticized the citizens, only allowing the aristrocrats to live (to pay taxes and help support the Robotnik Empire). He "hires" Sleet and Dingo to help capture any of the four who threaten his empire.

Bio: The brains of this two mobian team. Sleet basically tells Dingo what to do, and uses a special device that can transform Dingo into whatever Sleet wants (from a fish to a fly). Sleet is always cruel, and often the subject of falling objects.

Bio: The lacky of Sleet, this poor guy has brute strenght, but no brains what so ever. He gets confused easy, and is always being used by Sleet. Also has a sort of crush on Sonia. His ability to morph into any object when Sleet uses the device allows him to be the ultimate spy, just without the brain power.
