Doctor Eggman, disguising himself as "King Doc of Toreggmania" and Team Rocket, announce another World Grand Prix and promises vast riches to the winners (Sonic Free Riders belongs to SEGA, Pokémon belongs to Nintendo).
Sonic the Hedgehog is not safe. Everyone is out to get him. The only person on his side is Weiss Schnee, heiress to the Schnee Dust Company. She is not the best company to have. Together they must recover Sonic's rings of power so he can escape to the mushroom planet. But to do that, they'll have to outrun the evil Dr. Robotnik and his army of robots. Fortunately for Sonic, outrunning people is what he does best.
