Lets start with I don't own Sonic/Sonic Characters, but man that would be cool 8D

Anywho I figured it would be nice to do an fan fiction on one of my favorite Sonic games- Sonic Unleashed. This is based on it but I added my own twists to it, to add some spice to it of course. So yeah there will be differences, just saying that now but in the long run I hope the differences would be a nice touch. Alright I'll stop talking, please do enjoy ^-^

Sonic hitched a ride with one of Robotnik's robots. He had no clue where it was going but he figured it would bring him right to the doc himself. Once the blue hedgehog could see that he was now entering space, he began to wonder what in the universe Robotnik was up to. Sonic did not even let Tails in on what he was up to for he figured it was just going to be a quick job.

A fleet of ships were soon seen in the distance, Sonic could see that it could be a bit bigger then expected but it probably being Robotnik he figured to be done in a few minutes. He waited until a good time to drop down onto one of the ships. A few seconds went on by, another robot figured out that he was hitch hiking and started to fire. The robot went down onto one of the ships with a crash, the hedgehog though stood up and brushed himself off.

"Well thats one way to land" he said to himself.

Meanwhile on the main screen of Robotnik's ship he got an alarm that an intruder was aboard. The screen shown the blue hedgehog that more then once foiled his master plans. Robotnik pressed a button

"FIRE, get rid of that hedgehog" yelled the doctor

Sonic started to see robots start appearing out of holes in the ground. He wore a smirk.

"Its nice of him to give me a warm welcome" laughed the blue hedgehog as he raced towards robots that were firing at him. He quickly took them out and then some cannons showed up. Sonic glanced at them quickly before dodging their attacks by running on the walls of the ship, it was like Robotnik was using his whole arsenal against him.

Without warning a metal arm grabbed Sonic off guard so he could not dodge it. It then retracted backwards. Soon Sonic was face to face with his arch nemesis.

"That was too easy" muttered the evil genius as he looked at the blue hedgehog.

"Did you think seriously think I came unprepared?" said Sonic, there was confidence in his voice. He then closed his eyes and the seven chaos emeralds appeared around the hedgehog. The once blue hedgehog with green eyes was now golden colored with red eyes.

The doctor tried to grasp the hedgehog with the robot arm but the super powered hedgehog would not allow it and just broke himself free. Fear seemed to strike the evil doctor's face as he tried to make a getaway from Sonic. The golden hedgehog stood there for a second as if to let the doctor get a head start so it was be a fun chase.

Explosions happening from all around, confusion engulfing everywhere. Sonic seemed to be everywhere at once so Robotnik felt safe for a few seconds but then the hedgehog was behind him. The doctor in a panic began to shut all the doors behind him, that though proved to be worthless for Sonic had no trouble blasting through the thick doors.

The two of them found themselves in a huge room and then Robotnik fell out of his robotical chair onto the ground. Sonic stopped a few feet in front of him. The evil doctor then started to do something out of character, plea with the enemy.

"Sonic, please don't hurt me. I didn't mean to do it, honestly I didn't know what I was doing was evil"

Sonic looked at Robotnik with a confused look "Are your seriously turning over a new leaf? Well if you played nice in the first place Eggman I wouldn't have to break your toys"

The doctor held a odd looking button in his hand and said "For the last time, my name is Robotnik not Eggman!". He then pressed it.

"Wait,what" but before Sonic knew what was going on he was surrounded by weird looking columns which then grabbed him with a strange energy. He tried to run from it but could not. No matter how much he tried to get himself free it was futile. Robotnik was laughing at Sonic's lame attempts to get himself free. It got worse though was a sharp pain ripped through his body causing him to yell in pain as the emeralds were forcefully ripped away from him. Sonic could feel the power draining from him as the emeralds left his body and he returned to his normal blue self. He was becoming weaker but the pain was not stopping. Sonic then started to hear machines and what now looked to be a huge cannon.

Robotnik gave a evil laugh for his saw his victory in his grasp. With much joy he press a huge bright orange button and watched the cannon faced towards Mobius work it's magic. The planet was then blasted with a huge purple blast which went through the atmosphere with no problem and hit the what looked to be a body of water that could possibly an ocean. The force of the blast caused the water to be blasted up and the crust underneath began to crack from the shear force of the blast. When the crust cracked a strange energy seemed to creep out, only to be found out that it was no energy but an massive monster. Robotnik watched his plan unfold with excitement.

Sonic was aware of what was happening but there was nothing he could do for he was still trapped. He was in a lot of pain but stayed quiet for it had started to become unbearable and did not want Robotnik to have the pleasure in knowing that he was in pain. The hedgehog was all of a sudden feeling a strange sensation that took over his body within seconds which caused him to fall onto his knees. Sonic oddly started to growl, but in a low tone that was hardly even noticeable, and then clutched his hands into fists as if he was trying to keep himself together. His physical self was the first to seen changing, his arms started to become very muscular and his fur was beginning to become denser and thicker as well. Due to his slender body becoming muscular the gloves that he wore could not handle the sudden change and when his hands changed along with the rest of his body the gloves got shredded. Sonic released his fists revealing that he now had sharp claws. His teeth also started to change as well. He was making groaning sounds mixed with the low growl as his teeth grew, it sounded awfully painful. The teeth become noticeably bigger and even some of them become very sharp. After the transformation Sonic let out a massive roar, the laser field that held him gave way letting him free. He laid on the ground, the seven chaos emeralds fell around him. They though were grey and lifeless, they held no more power.

Robotnik wore a grin, his plan had began to unfolded perfectly. Sonic even played his part right by bringing the power for the cannon, it was great fun to trick the hedgehog into following his plans instead of having the plan foiled by the same hedgehog. "Success, a brilliant success. Just like what those Gaia Manuscripts foretold, there was an living life force within the planet's core. Now I just need to harness all that power and then Robotnik land will begin. This is my greatest ingenious plan yet"

Sonic was breathing heavy due to the massive change that he just had went through but was standing up now. He heard what Robotnik was saying that him turn around and glare at him.

"Seriously where do you get this stuff" said Sonic in a lower tone then usual, he sort of sounded mean.

Robotnik noticed that Sonic had transformed, he had not really a clue why that happened but it was something to be wondered. Sonic looked to have some canine mixed in him, making the ex-hog something different entirely. It kind of reminded the doctor of werewolf movies, it was kind of amusing. He bet that Sonic was not even aware that the change occurred, which made the situation even funnier. "Well Sonic that is an great look for you, maybe you can be useful as a mop or something. You out lived you usefulness, so long 'friend'" Robotnik seem to want to choke on the word friend as he spoke it. He then had a protective dome placed over him and his machines, Sonic wondered what the guy was up to. He soon found out when Robotnik opened the emergency door, with much force it started to suck Sonic out side into space. He tried to hold onto the ship but there was hardly anything to hold onto and soon lost his grip. Robotnik watched Sonic fly outside of the door and into space. He though also saw that the chaos emeralds were also ejected with Sonic, his expression dropped.

"Ah crap" he muttered under his breath seeing them float away towards Mobius with Sonic.

The energy monster was too massive and collapsed with a hissing sound,spreading itself through the planet of Mobius. From the space ships it looked as if an dark purple cloud engulfed the planet. Sonic just watched himself fall towards the planet that many times over he saved would probably kill him on impact with the ground.

Knuckles was sleeping on the steps to the shrine that belonged to the Master Emerald. The night sky was speckled with stars and overall it seemed like a nice,quiet, normal night. That night though was interrupted when a huge purple flash broke through the sky. It woke up the guardian with a jolt.

"What the hell is happening" said Knuckles to himself as he sat up and watched the light flash across the sky.

The laser hit the ocean and caused a huge boom. Water splashed up to unbelievable heights, even though it was a pretty far away he could tell the hit was massive. The wind that the hit made though managed to make it's was to Angel Island and it was pretty strong, Knuckles had gotten blasted off the steps. He was irritated as he got off the ground all of a sudden he had a sinking feeling.

The Master Emerald with no warning had lost its power, with out it Angel Island could not stay in the sky. Knuckles could not place what could have caused it to lose it's energy, which was bad because now the island would begin to fall and there was not anything Knuckles could do at the moment. He started to run to an edge of the island to get a better look.

He was not far from an end when a weird energy seem to start up, Knuckles could see what he thought were tentacles form up and then a monster thing appeared. It was thrashing about with what appear like anger. It hit Angel Island a few times, causing massive tremors that had Knuckles fearing the stupid monster was going to rip the island apart. The Master Emerald, Knuckles was sure was probably the safest thing on the island at the moment. The monster let out a spine tingling screech and it seemed to...fall a part, almost like it was melting.

Another strong wind hit, this one was pretty massive and just took Knuckles right off the island with ease. Knuckles forgot about the thing realizing that he was no longer on the island. He could see something was seriously wrong, it looked like the world was broken as he saw one of the cracks that was made. He was gliding so it was not life threating at the moment that he was blown off the island but another wind had hit. This caused him to be blown a few more miles by force and lose balance, making it harder for him to stay up. He knew he could not stay up much longer and slowly drifted towards the water, knowing that he could swim and it would be better to hit the water with less force as possible. Knuckles landed in the water with a splash.

And that concludes the first chapter, yay! Why yes I like Robotnik's full name but Eggman isn't a bad name but I think its more funny to have it be a name that he doesn't like to be called XD

So I'll try to get chapter 2 up as soon as I can, till then see you later :3
