Discovering an element known as Ragnium, Dr. Eggman starts harnessing it for himself, using it to create robots that can allegedly outrun Sonic and his friends while also damaging the environment in the process. Meanwhile, D-Fekt, a rejected robot Eggman created to search for Ragnium, starts using his magnetic powers to try to become more powerful. Sonic and his friends attempt to stop Eggman and D-Fekt and restore balance to the environment.
