A/N: Hi, this is neosonic2 here with my first-ever fanfic. I decided that my first fanfic would be a Sonic Adventure 2 fanfic, because that's my favorite Sonic game, and I believe it is the best Sonic game that Sega & Sonic Team have produced so far.

Italicized information either represents a term or concept. If this information is preceded by an A/N, that means that it's an author note, like what you're reading now.

Please don't forget to review this fanfic…but go a little easy on the reviews, because after this is only my first fic and so I'm real new at this.

Thanks for reading this fic! I don't know how long it will be but there will be quite a few chapters. Each chapter may or may not be preceded by an author's note.

So without further ado, let's get to the fanfic!

Sonic Adventure 2: A Promise Gone Awry

A Sonic the Hedgehog fanfic written by neosonic2

Chapter 1: Introduction

On a lonely, deserted island in the Pacific Ocean, one man plotted his next scheme. This man, however, wasn't like any normal man. He was heavyset, shaped like an egg, and had an enormous IQ of 300. In other words, he was a genius. He knew just about everything there was to know about science, technology, and how to invent things. But unfortunately he decided long ago to use his genius and resources for world domination.

So here he was now, this man, on his deserted island in the Pacific Ocean, trying to think and come up with a plan on how to defeat Sonic once and for all. Yes, Sonic, that pesky, spineless blue hedgehog we've all come to know and love. This man, this Dr. Eggman, if you will, hated Sonic the Hedgehog. He hated him mainly because of his speed. Sonic could go over 700 mph and even break the sound barrier if he tried. He used his speed to his advantage, often defeating Dr. Eggman in his quest to take over the world simply by sheer determination and speed. This was why Dr. Eggman was looking for a way to get rid of Sonic once and for all. He needed a master plan, something that he knew wouldn't fail. And little did he know that today would be the day that he would unleash his greatest and most dangerous weapon yet—a weapon so volatile that even Sonic might not be able to stop him this time.

And so, our story begins.

Dr. Eggman was sitting in the high-backed, throne-like green chair that was positioned conveniently in front of his main console. This console was where he controlled every aspect of his hidden base, located on a remote, deserted island somewhere in the Pacific Ocean. For some reason that Dr. Eggman couldn't quite put his finger on, Sonic the Hedgehog always seemed to figure out where Eggman built his new bases and would always eventually come and tear them down. Eggman hoped that Sonic would never be able to find this new, well-hidden base. After all, it was discretely hidden inside a giant pyramid that was surrounded on all sides by miles and miles of quicksand, something even Sonic couldn't travel through without help.

"Dr. Eggman, content search complete," said the synthesized voice of a worker robot that had just entered the room. "Excellent, E-117," said Eggman. "What have you found?" "We have searched through all of your files and have not found any schemes or plans that we think would stand up to Sonic based on the criteria you provided us with," the worker robot said. "However, we did find one floppy disk that contains data on it that we cannot decode. We think it may be useful to you, sir." "Hand it here!" said Eggman, a little too eagerly. For days he had been commanding his worker robots, including the new E series line of robots he had been working on for some time now, to search through all of his files, disks, cabinets, etc. looking for some "new material" – some kind of new scheme that Eggman had never before used on Sonic. So far the search had not gone over well, but this most recent piece of news left Eggman a little over-eager for excitement.

The worker robot handed Dr. Eggman the floppy disk, and he quickly proceeded to put the disk into his computer. After taking a second to read the disk, his main computer screen lit up with the following information: "Password required – A password is required to access the data stored on this floppy diskette. Please type the correct password and hit the ENTER key to begin accessing the data. Password hint: Gerald." "Password?" Eggman asked himself, "I don't remember encoding any of my disks with a password. I've never had the need to. I wonder how this disk got in here... And I wonder what the password is too."

Eggman thought for a few seconds about what the password might be. He considered the password hint given to him by the computer, and then suddenly snapped his fingers, a possible password popping into his head. He faced his keyboard and typed, "M-A-R-I-A" into the console and then hit the ENTER key. The computer screen went blank, to be replaced by a progress bar that slowly started to creep across the screen. After a few seconds of this, the screen went blank again, this time being replaced by a list of the files on the diskette. "Excellent!" Eggman exclaimed, "That was the right password!"

Eggman proceeded to look through the files on the floppy diskette. Most of them, he noticed, were of military records or machine construction information for his various weapons, ships, and vehicles. But there was one file with a name he didn't recognize, called "Project Shadow". He double-clicked on this file, and while the computer proceeded to open it he thought to himself about what the file might possibly contain. Finally, his word processing program started and the contents of the file appeared on-screen. He stared intently at the document, trying to read what it said. It appeared that the document had something to do with a research project codenamed "Project Shadow". This project, according to the document, had been shut down sometime in the 1950s by a military organization known as G.U.N, or Guardian Unit of Nations. Apparently the project had been cancelled because there had been an accident on the ARK, the space colony where research and development on the project had begun. The document went on to talk about the various powers that Project Shadow would have, among which were its vast array of weaponry and fighting know-how, and, something that really caught Eggman's eye, its immortality.

"This is perfect!" exclaimed Eggman. "This is exactly what I need to get rid of that pesky, high-speed hedgehog once and for all! All I need to do now is to figure out how to get into G.U.N's base so I can steal Project Shadow. The file said that the project had been placed there after the ARK had been shut down, but it didn't tell me how to get into the base. No problem, though. With all of my advanced machines this should be a synch. Sonic, look out, because I, the evil Dr. Eggman, the greatest scientific genius of the world, am back. And this time, there's no stopping me! Muhahahahahahahahaha!"

A/N: Well, that's the first chapter. Kind of short isn't it? The first chapter is always the hardest to write, so they'll probably get longer as I go along -- remember, I'm new at this.

After writing this chapter and submitting it, I realized I had left out some very crucial info in my author's note. So this is why there's one down here. Anyway here's the info I left out.

(1) I will update this fanfic often, every few days or so as inspiration strikes.

(2) At the beginning of each chapter there will usually be an author's note that has comments about the reviews I've gotten (if any) since the last chapter, as well as a few other details and copyright info and stuff.

(3) Please review. It's what helps me to grow as a writer and its what inspires me to continue writing and submitting chapters. Thanks in advance to everyone who reviews.

(4) The standard Sonic disclaimer applies. I don't own anything having to do wiith Sonic, but I wish I did, because then I could make the games better than they are now.

Guess that's it, thanks for reading this chapter, and I hope to have the next one up real soon! Oh and you can now follow my updates to this story on Twitter, just look up the username neosonic2. And, if you want other creative ways to review my chapters, and you've got Skype, look me up on Skype at neosonic2 and we can chat/talk for a while about what you think of my story.
