Dr. Eggman is at it once again. This time, he's discovered a supercharged element, known as ragnium, on the mythical island of Ragna Rock.

Dr. Eggman uses the supercharged fuel to power his ultrafast bot racers in a new plan to discredit his eternal rival, Sonic. Plus, with his powerful ragnium, fire and ice, a vast robot army and his new and unflinchingly strong henchman, D-Fekt, backing him, Dr. Eggman may actually succeed this time.
