Summary: What would have happened if Sonic didn't beat Perfect Chaos, but Shadow came back in time at the request of a human girl and a hedgehog boy, and defeated Perfect Chaos for the blue hero...?

Prologue: A shadow of the past awakens

Two small figures bumped against each other, immediately, the two creatures hands were at each others throats. "Identify yourself!" They hissed at the same time, recognizing each other's voices they dropped each other. "Darren?" "Sally?" They both sighed in relief and hugged each other, the girl was a human, the boy was a hedgehog. The corridor they were in was dark, damp, and had an abandoned air. "Do you think that somethings REALLY in here?" Asked the boy rubbing his arms for warmth, the girl did the same and looked around, "I think so, besides, what better place for hiding something than an abandoned place no one would think of looking in?" The hedgehog smiled, "You did." The girl pondered this awhile, "True. But they don't know me personally do they?" On the outside, the girl looked pleasant and eager to make people happy, she had raven black hair that fell around her face, well, the amount that wasn't held up in a ponytail. "Which corridors have we not searched?" She asked. He looked at a map which had x's all over it. "The one to our right." The turned, this one, if possible, seemed even more abandoned than the others. They went down it cautiously, aware of every tiny sound, not that anything could be heard except their breathing and the treading of their shoes. "What is that?" The boy asked, his voice slightly high from panic. "Sh Darren, you're okay." The girl advanced, it looked like a strange capsule of some kind. There was a slot at the top, the girl pulled a dully glowing emerald from her pocket and put it in, it fit perfectly, then she turned to the keypad. "Sally?" The boy sounded like he would scream any moment from terror, ignoring him, the girl turned it over, a note was tapped to the back, in tiny writing, the word could only just be deciphered, MARIA. Sally set it back down and typed the five letters. Instantly steam hissed and the pod slowly opened, the girl and the boy backed away as a dark figure hidden in fog stood up and turned, and started walking... STRAIGHT TOWARDS THEM.
