Chaos Control

(Sonic)

It seemed like such a nice day in the green hills of Mobius, the birds chirped in the vast great forest that many animals called home, flowers where now fully bloomed, a calming feeling radiated through the forest, however, there was also a feeling of panic. Deep inside the forest concealed by very high hills, was a small town, or more along the lines of a camp, the houses sure looked like cabins.

The people though they were not people, they were animals, and they looked more worried and scared then happy go lucky. However in a much bigger cabin near the front of the town, were six other animals, they were sitting around a huge table that seemed to hum. The animals varied between a purple walrus wearing a yellow hat and brown jacket, to a hybrid robotic rabbit, with a cowboy hat, pink shirt and brown vest.

However there was one animal that seemed most unique, His fur was blue, as well as his quills on his back, his stomach was more peach like in terms of color, as well as his face. He wore white gloves on his hands, on his feet where red shoes with a single white stripe in the center going from one side of the shoe to the other. His eyes were closed as his feet where kicked up, he looked more relaxed than anything, to relaxed in fact, he was sleeping.

The only one standing was a female squirrel; she had brown fur except for some tan fur around her face, chest and stomach, she also had red bushy hair. She had an open blue vest as well and knee-high blue boots. Her blue eyes were on the table as she pressed a button on the side showing a dark fortress all the animals except the sleeping hedgehog took an uneasy breath as they saw it.

The girl sighed to herself as she looked over everyone, she knew this fear a bit too well, many a time they had seen this city, and many a time had they been to this city but this was to be the last time.

"Freedom Fighters, today is the final battle," she started "Today we fight the odds and march into battle, to not only save our world but to return our friends and…family to the way they were."

The room was still silent except for the soft snoring of the blue hedgehog. The girl glared at him and crossed her arms taping her foot on the ground waiting. Next to the hedgehog was a small fox, he had yellow fur all around his body, he had three hairs sticking out of his forehead, and he had white fur on his face, chest and stomach.

He looked like the youngest one there, when he moved to grab the hedgehogs arm to shake him awake, it showed he had not one but two tails, they where as well yellow but half way up they turned to white. He continued to shake the arm of the blue hedgehog till it finally started to open his eyes slowly.

He stretched a bit and shook his head as he opened his eyes fully now. He looked around and was confused why everyone was looking at him. "What?" he asked.

The girl sighed loudly "Sonic, why do you even bother coming to these when you aren't going to listen?" she asked him.

The hedgehog just smiled and said "Sal, you know me, I get sleepy during meetings."

The girl sighed and placed a hand on her head like she had a migraine, witch seemed to happen a lot around Sonic. "Do you at least know the plan?" she asked him

Sonic now had a smirk "Yeah, while you guys get all the generators shut down I will be finding Eggman , and teaching him a lesson he won't forget." he said.

The girl who was named Sally nodded feeling a bit relived as she looked into Sonics emerald green eyes, she always could trust him, always believe in him to do the right thing, even when it looks bad.

Sonic smiled and leaned back again "Sal is right though this is our last fight, this is the day we teach the good doctor who's in charge!" he said.

This time the other freedom fighters looked less scared and some even cheered a bit. Sally wasn't that surprised at this, Sonic was the one that gave many of the freedom fighters the courage to fight.

Sonic smiled a bit as he looked around, he knew this was possibly the most dangerous mission to date, but this needed to end all the pain that man had caused to many friends ternd into mindless slaves to his empire, he had have enough of it.

In the city there were no light, the air was so polluted breathing it was considered dangerous, and there where once again no people, only machines, everything hummed with electrical power, that was what the freedom fighters where here today to make sure these machines never hum or work again.

They were all together in one section near a dump of old robot parts and mechanics, Sonic was taping his feat and just trying to stay active, he hated staying still. He went over the plan one last time before the teams went there separate ways to the different generators.

It was only Sonic Sally and the two tailed fox boy who was named Tails. Sonic knew this was a solo job for him, and he didn't what to get anyone hurt, "Liston guys if anything happens stick to the plan." He said.

The other two looked a bit worried but nodded slowly, Sonic was about to leave when Sally grabbed his arm and kissed him.

She pulled back a bit with small tears in her eyes "Be safe okay." She told him softly.

Sonic smiled a bit as he hugged her back "I always am" he said winking at her. "Tails keep her safe okay?" he asked his friend.

The fox smiled and nodded "You got it Sonic; I won't let anything hurt her." Sonic nodded as he let go of Sally who also had a smile on her face as she stepped back.

"Hold onto something guys." He said as he ternd around. As commanded they held onto some sturdy and heavy parts of old robots. The blue hedgehog smirked a bit as he stretched his legs out, then in one sonic boom he was off running at speeds no machine could ever match.

He blurred down roads and past robots, some who got too close to him got blown away, and he loved every minute of it, he loved being able to see the world blur around him as he sped around it, he felt invincible, untouchable.

He snapped out of his little day dream when he saw a huge building in the distance quickly getting bigger. He had reached his target, now to get in word be fun. He smirked to himself as he ternd slightly and found an old piece of metal sticking up like a ramp. Sonic not being scared of taking risks used it to propel himself airborne and head straight for it. But before he made impact to the building he curled into a ball making his blue quills the only think that could be seen, It impacted and broke a small hole in the wall. When the smoke cleared he was standing once again, he smirked as he started to run again heading to the top of the building.

It took only a minute at most to get to get to the top, Sonic stopped when he almost slammed into two giant doors. He knew what was beyond them and he wasn't afraid or if he was he wasn't showing it.

He knocked on the doors, "Hello anyone in there?" he asked. The doors started to open slowly to a dark open room. Sonic was caught off guard at what he saw in the center. A huge green emerald sat in the center of the room radiating green light. Sonic knew what this was, but what troubled him was why it was here, he got tense as he looked up and saw a giant robot, it looked incomplete but the face was all to familiar to the blue hedgehog. Then the lights came on and the entire room was filled from top to bottom with black robots their arms pointed to Sonic with a clip on their hand that glowed red.

Sonic looked around a bit then herd laughing, he turned around as a small door opened from the ceiling, coming down in a small chair sat the man himself, his evil red eyes, burned into Sonics sole. He was a big guy dressed in a red lab coat, he had on black pants that went over his stomach, his head was bald but on his head where a pair of goggles. He had a very long brown mustache on his face that just made him look more evil.

"Welcome Sonic, oh I do hope you like the surprise I have here for you, it took me months to plan this out." The evil doctor said.

Sonic looked around at all the robots and chuckled a bit "Not bad Eggman, got to admit this is one heck of a surprise…never saw it coming." He said smiling.

The doctor smirked a bit at him "Well I'm glad, for you see my little blue friend your end is here!" he said pointing to Sonic "Swat Bots make quick work with him." He said as he pushed a button on his chair, he started to go up but the emerald was as well. Sonic saw that and tried to stop it but got stopped by a laser to his feat, it missed but it got the message clear, he needed to get rid of these guys before he could get to Eggman. He took a deep breath and smirked "Okay boys come and get me!" he said getting down low.

It got chaotic fast all the robots firing there lasers at once at the blue hedgehog, he was moving back and forth jumping from wall to wall to avoid getting hit, but even he isn't that lucky. One robot grabbed him by the leg and tossed him into a wall. However inside the wall a blue streak came out going throe the robot and making it explode.

Sonic was tired but he continued to fight on curling into a ball and playing pin ball with all the robots taking them down one by one, till there only a few more left. Sonic landed on the ground after he was hit with a laser knocking him out of his pin ball craze. He was breathing hard almost out of energy, he slowly stood looking over the rest of the robots, he glared at them and charged at them as they fired there lasers.

Another dust cloud went up, concealing the rest of the fight, but as the dust settled one thing was standing a very tired blue hedgehog. He was breathing deeply now, he never fought that many before and he felt like he got lucky, he fell to his behind and tried to catch his breath. After a second or two he stood up and jumped turning into a ball and smashing the door that Eggman and started to role his way to the evil mans location.

Sonic landed on his knees as he arrived, he saw Eggman with a smirk on his face as well as the giant emerald behind him glowing still. "So you decided to join me Sonic." He said with an evil smirk.

The hedgehog stood up and smirked as well "Just had to take care of some your guests." He said pointing to the small opening in the ceiling. "Now the real party will begin, but first tell me what you are doing with that?" he said now pointing at the giant emerald.

The doctor smirked a bit more as his eyes glowed a bit looking over at the gem then back to sonic " That my little blue friend is a secret." He said. Sonic looked more closely and saw that there where wires sticking into the emerald, conceited to a generator. "Even if your friends shut down my other generators, this will give me power to destroy them as well as that little village you call home."

The smile left sonic fast as he now glared at the evil doctor, "Like to see you try!" he said as he charged at him. The man didn't back away as another blue streak came and slammed into Sonic sending him into a wall.

Sonic slowly got up and saw another hedgehog only this one was a robot, it had evil red eyes as well a turbine on its back, and its red shoes almost matched Sonics. The evil man laughed again "You can't win hedgehog, just give up while you still can!" he said.

Sonic slowly stood up as he glared at him and his robot look alike. "No way Eggman, my adventures don't end till I stop running!" he said charging once again at the robot and him.

"Take care of him Metal Sonic!" Eggman said as the machine also charged at Sonic. They collided at full force sending them in serpent ways, Sonic was able to turn himself so he could land on a wall and push himself off turning into a ball and colliding with Metal sending it to a wall.

Eggman was cheering as he jumped up and down "Go Metal show that hedgehog whose boss!"

Metal had Sonic by the neck as he choked the life out of him he was flying in the air no way Sonic could kick off of something or anything. Sonic choked a bit his hand moving behind him reaching for something, Sally had given him before coming here. He grabbed it and smiled a bit at the robot he pulled out a gold ring and held it in his hands he felt power surge thru him as he instantly entered into a ball and started to spin at fast speeds. Metal was sent flying right into the generator; Sonic soon lost that energy and landed face first on the floor.

For a while there was no sound, and then an explosion could be heard Eggman looked to see what it was on one of his screens and was shocked "What! One of the generators, no two…no all of them are exploding!" he said a bit panicked.

Sonic lifted his head and slowly stood as he looked at the emerald, it was glowing even brighter and it continued to glow brighter. Eggman was panicked "This can't be happing the main generator has entered reverse, it's giving power to the emerald!" he said.

Then what seemed like on cue there was a loud roar so loud it maid Sonic jump a bit yet it also sounded…familiar.

The emerald was now glowing as its power started to shine even more and as the light got brighter and brighter as explosions could be heard all over a single white light shot from it and Sonic blacked out.
