This is my very first fanfic, so I have chosen two of my favorite shows, Sonic SatAM and Digimon Season 3. I'll try to put most of my notes at the end of each chapter so you can get to the story faster (aren't I nice). Remember that this is only the prologue, I'll try to make my future chapters longer, until then, ENJOY!

Disclaimer: If I said I owned Sonic or Digimon, I'd be lying through my teeth.

Tails's Transition

Tails was traveling through the Great Forest to the secret village of Knothole. The forest was just as green as ever in the late spring noted the two- tailed fox. He paused for a moment and closed his eyes to allow a cool breeze that had just come up to flow through his brown fur as it rustled some leaves in the trees above him.

It all seemed so peaceful and serene that it was almost hard to believe that just nine years earlier, Robotnik had come so very close to destroying all of it with his Doomsday Project. If Sonic and Sally didn't use the Deep Power Stones to destroy it, the entire planet would have become a technological nightmare just like Robotropolis was.

With the threat of the Doomsday Project gone and Robotnik dead, they thought that they could finally rebuild Mobotropolis and restore it to its former glory, but Snively somehow survived and assumed control over Robotropolis. It took them another long, hard year of fighting before they finally overthrew him and reclaimed what was originally taken from them. Eight years afterwards, they had been able to rebuild most of Mobotropolis.

After the wind had died down, Tails opened his eyes and resumed his trek towards Knothole with a more refreshed feeling. While he walked, he gazed at the treetops above him and began to reflect on a more recent. This was when Sonic's uncle, Sir Charles Hedgehog, had finally perfected the deroboticizer. It was a real jubilation when the last of the Mobians had been returned to their original states, especially for Bunnie whom had wanted for the longest time to be normal again.

Tails was still lost in his thoughts when he felt a strong gust of wind pull him forward with a sudden jerk. He snapped his head down in time to see an almost blinding white portal that was dragging him towards it with increasing force.

Before Tails could wind his dual- tails up to fly far enough away so he wouldn't be affected by the pull, he was already sucked into the vortex of swirling, white light. When he was through, it seemed like he was falling into a void of nothingness. He managed to twist his body around in the empty space to see that the portal behind him had closed completely and that that direction was just as blank as what he had turned away from.

It was like falling through water he could breathe, everything seemed to slow to a crawl. Tails continued falling, although it wasn't so much as falling but floating downwards, into the seemingly never- ending abyss when he landed with a loud splash in the cool waters of a lake. Fortunately, he managed to remain calm enough to swim to the shore. He slowly crawled out of the water and onto the bank, sopping wet. After shaking himself off, he could already feel the warm rays of the sun start to dry out his fur.

Tails scanned his surroundings and noticed that he still seemed to be in a forest due to the fact that trees surrounded the lake he had fallen into. Although he greatly doubted that he was still in the Great Forest since he couldn't recall ever seeing the lake he fell in anywhere there.

Tails was ready to take to the air to get a better view of the area when he got the strange feeling that someone or something was watching him. He dismissed it as just nerves since he was still a bit disoriented from the ordeal he had been through. When he was only a few feet off the ground, he heard something disturb the leaves behind him. He dropped to the ground and spun around to see what had made itself known to him, but couldn't even see the movement of the leaves he just heard. He was wondering if he was letting his imagination run wild when he heard a low, almost emotionless female voice behind him ask, "Who are you?"

Tails turned to face his inquisitor and was relieved to see what could only be another Mobian. She was a vixen who appeared to be about the same age as him, although she was a couple inches shorter, roughly 5'5''. She had calculating deep blue eyes, purple gloves that almost reached her shoulders with the yin- yang symbol on the back of each hand, and ears that were slanted back at an extremely sharp angle. Her fur was a goldenrod color.

The blue- eyed vixen asked again with the same icy voice after his long silence, "Well, who are you?"

Tails realized that he had been silent for longer than he should have been. "I'm Tails." He answered since he wasn't in the habit of using his real name, Miles Prower. He was about to ask her for her name when she said the oddest thing he had ever heard.

"So you're not a Digimon." She said as if he was supposed to know what a Digimon was.

"What exactly is a Digimon?" Was all he could say after hearing such an unusual statement.

The concept of vulpine Mobians and certain other species being taller than four feet was, as far as I know, the idea of Joseph DelaCroix in the fanfic "Starship Down".

This is nine years after the Doomsday Project so the ages set for the characters are, Antoine: 27; Sonic, Sally, and Rotor: 25; Bunnie; 23; and Tails: 19.

This is 1 year after the D- Reaper incident in the Tamers Season so their ages are Takato, Rika, Henry, Kazu, Kenta, and Jeri: 14; Ryo: 15; and Suzy: 8.

If you have any questions, feel free to ask in your reviews.

Last note; I'll be starting on some other Sonic crossovers and try to update them along with this story in turns.
