Prologue

The reality-warping power of the Super Genesis Wave ravaged the planet Mobius, spreading outward throughout the entire cosmos! Dimensions convulsed and universes burned in the ensuing chaos! Only Sonic the Hedgehog and the New Freedom Fighters are aware of the change and the reality that never was. However, the mad scientist Doctor Eggman also remembers how things used to be — he was the man who induced the Super Genesis Wave in the first place. It seems that after his attempts to secure control over the Mobius dimensions Dr. Eggman still came out of the situation with more knowledge than before. He uncovered special properties concerning the "Genesis Portals" that were exploited in his previous endeavor, and now he's on the hunt not only for the seven Chaos Emeralds, but another power source, one that in itself equals the limitless potential of the great gems of the Chaos Force. The Freedom Fighters alone will not be enough this time around. The world's greatest heroes will need the assistance of others, others who have proven their worth as the noblest of fighters saving the planet from terrors the likes of which equal the monsters that Sonic and his friends have fought in the past. For this fight, our heroes turn to the East for assistance in the battle for all things, and our fate rests within their hands.
