History
After regaining the Jeweled Scepter from Captain Whisker and his band of pirates, and obtaining the Chaos and Sol Emeralds, Gardon told Sonic, Tails, Blaze, and Marine that someone broke in and stole the Jeweled Scepter. Shortly, a greater earthquake occurred and the group went outside, the Egg Wizard suddenly appeared and Dr. Eggman appeared along with Eggman Nega and told the group that they built Whikser to steal the Scepter so they could unleash the Power of the Stars. The Eggmen left to get the Power of the Stars (which was under the Southern Island) and Sonic and friends went after them in a new machine, built by Tails, called the Magma Hurricane. Once they get there, they saw they were too late as the two Eggmen got to the Power of the Stars and threatened to destroy both Sonic's world and Blaze's world and create a multidimensional Eggmanland. The immense power seperated Sonic and Blaze from Tails and Marine and Eggman and Nega also said that both Emeralds couldn't compare to their power. Nega also threatened to destroy Blaze's kingdom and taunted her ancestors, saying that it was their duty to protect the Scepter and that their help was much appreciated. This angered Blaze, but Sonic got her to calm down and they used the Emeralds to transform into Super Sonic and Burning Blaze. They then challenge the Egg Wizard for the sake of both worlds and Blaze's kingdom and people.

The first section has the Egg Wizard fly away and Super Sonic and Burning Blaze much catch up. Once they reach the Egg Wizard, Blaze has to fire some fire balls to damage the Egg Wizard. At times, the Egg Wizard may fire three dragons will can be reflected back with Sonic's deflect ability. After enough hits, the Egg Wizard will fly away and Sonic and Blaze will give chase again. Sonic and Blaze will gain 24 more rings along the way. The second section is much like the first, but the Egg Wizard will perform an electric attack that will stun the player for a few seconds. After a few more hits, the same thing happens and the Egg Wizard will perform another attack, which is a group of missiles. The ones with a blunt tip can be deflected.

After the fight, Eggman Nega presses the "Planet Buster Cannon" button to try and destroy Sonic and Blaze, even though Eggman told him not to press that button, but suddenly, Marine hits the Egg Wizard with some kind of odd, green ability from her hands. Blaze uses this opportunity to hit the Egg Wizard, throwing it into the air, while Sonic comes from behind and charges at the mech from behind and exits through the jewel on the front and the Egg Wizard explodes. The player then is graded on how much time was spent and how many rings the player has left.

The next morning, Tails said that he used both sets of Emeralds to build the SS Tornado EX to get Sonic and Tails back to their world. Blaze offers Sonic a handshake and the two depart. Sonic and Tails start wondering where Marine was and just before they lift off, Marine appears on the S.S. Super Marine and Marine is upset that they have to go and they promise to see each other again some day. After the credits play, Blaze and Marine look off into the horizon with Marine in tears to see her friends leaving.
