In Sonic Riders, Dr. Robotnik has set up a speed challenge, and all the Sonic characters, including Sonic the Hedgehog, Knuckles the Echidna, Storm the Albatross, Jet the Hawk, Miles "Tails" Prower and Web the Swallow, have decided to compete.

in other words, all your favorites and three no-hopers.
