This is my prequel to Files, and is the Turbo Tails incident they talk of. You do not need to read Files to understand this, and neither do you have to read this to understand Files. I do not own Sonic and all related titles. This takes place right after Sonic Adventure/Sonic Adventure DX. And I mean right after. The night after basically.

Part I for Turbo Tails: The Fight Against Metal Sonic

Metal Sonic's Plan

"Those pitiful worms, they're celebrating," Metal Sonic spat as he made his way into his base, one far smaller and more secret then his creator's.

"They've defeated Chaos but the Chaos Emeralds have been scattered once more, giving me a chance to collect them. Then I'll be able to use them against Sonic. Super Metal Sonic will prevail!" the metallic being ranted, clasping his cold claws together for emphasis, even though no one was around to rant at.

Metal Sonic then turned into a room and linked up to the computer, downloading the information on the location of the seven Emeralds. With the data intact, he left his base, ready to carry out his plan.

Amy had talked them into celebrating. Amy, Sonic, Tails, and surprisingly Knuckles were in Station Square, Chaos using the last of his Perfect Chaos powers to repair what he had destroyed. The four were mostly ignored, having been saving the world quite a while now.

Knuckles, being the eldest, felt he had to be responsible, and made sure to lead them away from the nastier parts of town, which Sonic helped Knuckles on that part.

Finally they decided to a feast, and movie, and a small scuffle came deciding on the order.

When everyone's stomach growled at the same time, a feast was declared the victor, and they hurried off to an all you can eat buffet, which graciously let them in and let them eat for free.

Finally, stomachs nearly full (They were saving room for popcorn and soda at the movies), the group stumbled into a movie theater and watched Chao in Space.

All four, now experiencing the feeling where you want to sleep and run at the same time, decided to find a place to sleep.

One hotel later they had four rooms, paid for on a discount insisted by the manager.

As they slept, they knew nothing of the hideous plan of Metal Sonic.

Dr. Ivo Robotnik, more commonly know as Eggman among normal folk, was looking at his computer screen. As luck had it, a Chaos Emerald had appeared by his base, and he grabbed it. A file data was shown on the scientists grandfather's legacy, something about a Project: Shadow.

Eggman saved this file to his database, intending to look into more at depth later. For now he was busy rebuilding the Egg Carrier, hoping to make it more powerful and deadlier.

A loud alarm sounded through the base, as an intruder was detected. Robotnik growled as the security measures were activated. He wondered who had managed to get into his base, and also why were they here.

The unmistakable sound of explosions was heard in the distance.

The noises grew louder, and Eggman hoped that the last one he heard was the intruder gone.

The alarm still sang it's shrill cry, and the scientist pressed a button, covering himself in a protective bubble.

Nothing short of showing him the future could have prepared Eggman for this surprise.

The door was thrown open and Metal Sonic walked calmly in, eyeing the scientist.

Having little resources available due to the Egg Carrier's destruction, the scientist was helpless as the traitor and metal version of Sonic plucked up the prone Chaos Emerald, gave a wave and placed a small bomb on the desk.

When he looked back on it, Eggman was thankful he had put on his protective bubble.

The explosion rocked the compound, reaching the generator room and causing more explosions throughout the whole base. When it ended, Eggman struggled out of the ruins, and saw the destruction.

Grumbling about the fact he would have to walk to his secondary base, he dusted himself off and headed out, making sure his small hand held laser was charged.

Sonic awoke peacefully. He was lying on a huge bed, well, huge for him at the very least, and at peace with the world. He turned on his back, then turned his head and glared at the alarm clock. It read 11: 34.

The manager had insisted they sleep as long as they wanted, and Sonic, still tired from the fight and celebration, drifted back into dream land

Tails awoke a few minutes later, and having plenty of rest, he decided to try the TV.

Not wanting to see the news just yet, he watched a few cartoons, smiling at the antics of the unreal characters. Finally he changed the channel.

Someone was reporting the destruction of Eggman's base. Tails groaned. They had, had enough action for now, could it not rest?

Seeing as it was Eggman's base that no longer existed, that pointed out someone else was in the game. Tails wondered who.

Knuckles awoke a little past noon, surprised he had slept so long, then remembered he had not slept very much when finding the pieces of the Master Emerald.

Deciding to just listen to some music, he turned on the radio in the room, finding a good station, and just relaxed.

Amy awoke about ten minutes before Knuckles, and turned on the TV. She began to watch shows here and there.

Metal Sonic, in the dead of night, had already gather three Chaos Emeralds, and was soon to reaching the fourth.

The robot slid down a dirt path and into a rural area. A few cows were grazing in Metal Sonic's general proximity, but paid him no mind as the being scanned the area. Finding the Chaos Emerald, he boosted forward and grabbed it, then flew off, giving young Susie Jorgans a story to tell about the blue rocket.

Several hours later the fifth Emerald was collected, Knuckles was back at Angel Island, Sonic was asleep at Tails workshop, Tails was working on a land fighting mode for his plane, and Amy was at her apartment.

Doom was in the air, and only Tails had the inkling of it.

More hours passed, as Sonic finally got up and had a lunch of chili dogs, the sixth Emerald was gathered by Metal Sonic.

One hour later, Metal Sonic had all of the Emeralds.

Metal Sonic's plan was simple enough; Collect the Chaos Emeralds, go Super Form with a large number of Rings, cause mayhem until Sonic showed up, then kill him.

Metal Sonic allowed himself something he rarely did, an evil laugh, more of a chuckle if you will, as the seven Chaos Emeralds circled him. He blue body changed to yellow, and the robot flew towards Station Square.

Halfway there a thought entered Super Metal Sonic's mind. The Master Emerald could stop him.

He changed course and headed for Angel Island, a plan enough to take care of that.

What is Super Metal Sonic's plan? Just how many Rings did he collect? Will the battle take place soon or not, and how will Super Metal Sonic be defeated? Find this out and more! The next parts. Hehe.
