A quick note: I have not played Sonic Unleashed, nor have I watched playthroughs. This story is based purely on the cutscennes, so if I miss a boss battle or how to play a level or a boss battle, don't judge. This is meant to follow the cutscenes with me playing around and adding characters and my spin on it. If you have something against that, Don't read.

Now that that's out of the way, I'm starting up a new story. This one'll be easier cuz I don't really need to think of what comes next. Well, enjoy!

Disclaimer: I don't own Sonic and Co. or Sonic Unleashed. If it wasn't obvious.

Chapter 1: Changes

Space was reasonably peaceful. It was rather quiet, as sound had trouble making its way through nothing. Well, unless you live on Mobius, that is. Then again, laws still had to apply there as well, right? And, if you're a certain egg-shaped genius inside your own little spacecraft, you can hear sound, as there is air in there, right? You'd be correct. Said scientist was currently laughing in triumph. He'd destroyed the Tornado; blasted it to smithereens. And even if you were a two-tailed fox who-and the man had serious trouble admitting this-had an IQ that could nearly match your own, it would be difficult to rebuild a plane in so little time.

Eggman's laughter died and he turned a curious glance outside as a loud boom of an explosion sounded from outside, and then as sirens began blaring. Remember what I said about laws still having to exist on Mobius? Well, you could circumvent said rules if you were a blue supersonic hedgehog. Eggman had his theory that all normal laws and rules had long-since given up trying to restrain the hedgehog. Never worked when they tried. But, he had to question quite a few things. Like, how-in the name of Chaos-could that hedgehog breathe in space? Or stand on the ship, or jump and come down with no gravity, or how he wasn't freezing, or how he was able to make noise come from something in space, or-never mind. But, how had he gotten here so fast? Granted, he was a supersonic hedgehog, but not even he could fly! Well, unless he was Super Sonic. But he wasn't.

The hedgehog straightened up-almost lazily-and stood, a slightly amused smile on his face. He made no further move as Eggman snarled. "How did-? Never mind, take aim!" He slammed a fist onto a bright red button and the turrets mounted on his ship rotated until they were aimed at the hedgehog, who was currently re-lacing his shoe. A swarm of robots rose from the floor and took aim as well. The hedgehog glanced up-almost surprised-as he finished re-lacing the other shoe. A haughty grin passed over his face as Eggman threw a hand forward, screeching. "FIRE!"

Only then did the hedgehog move. He lunged forward, ducking underneath the barrage of missiles and bullets with ease. He grinned, jumping and ducking as he flashed by. On one particular jump, he tucked into a tight ball, slicing through five robots in the same amount of seconds. The final jump sent him high into the air, where he uncurled and gave a loud whoop. Eggman couldn't help but let his jaw drop. The hedgehog was actually enjoying this! He didn't get the chance to question the hedgehog's sanity, as Sonic had curled up again, then hit the ground running-literally. Another round of robots awaited him, and he allowed himself to have a little bit of fun with a few, running circles around-and sometimes on-the robots, then allowing them to teeter to the side, where they struggled to get back on their feet. Having the same general shape as your creator had downsides.

Eggman gave another snarl of frustration. The hedgehog was going to rip all of them to shreds in no time at this rate! Not that this was anything new, but he had just made those ones! Brand new models all of them! Well, they weren't the only new thing. He smirked as he pushed another button, his chair dropping down suddenly into a large battle suit.

Sonic glanced up as something jumped down from a nearby tower, and his eyes widened in slight surprise. He yelped and ducked as a barrage of bullets immediately fired from it, and he jumped into another spindash, giving a slight grunt as a bullet nicked his ear. It stung, but nothing he couldn't take. The next jump sent him high into the air, and he could hear a muffled: "Why you little-"

He cut Eggman off with a grin and smart retort. "Watch the language, Egghead!" His spindash took him directly before the robot, and he slipped between its legs with a roll before uncurling again and racing away. Eggman immediately reacted, turning and launching the first round of missiles out the robot's back. Sonic turned at the sound of the explosions, slightly confused. His face cleared and he returned his attention forward again as a loop-de-loop reared up in front of him. He raced through it, now dodging the rockets as well as bullets as his nemesis began to fire again. One of the missiles blew up close behind him-he could feel the heat-as he turned to speed down a long corridor. Eggman gave a snarl of frustration, just the rodent's type. Run until your enemy follows you. The snarl disappeared into a smirk. How good it was that he was prepared, then. "You're not getting away!" He pushed another button, and the barrel of the guns on one of the robot's arms turned into a giant metallic hand. It shot forward with incredible speed, attached to an impossibly long cable after the blue hero.

The final missile exploded in front of him, and Sonic coughed as he plowed through the smoke. He chanced a look behind him as the smoke cleared, and his eyes widened as a metallic hand reached forward out of nowhere. He gasped as it swept his feet out from under him, and then retracted with a jarring thud. He squirmed desperately as Eggman grinned at him from inside his bubble. He struggled in the grip. It was cold, and holding him far too tightly for his tastes. Realizing he couldn't escape through ordinary methods, he gave a smirk and closed his eyes. The Chaos emeralds appeared around him, all seven colors showing up on his blue fur and glinting on the metal holding him captive.

Eggman leaned forward, his eyes widening. "What?" He maneuvered the other hand of the robot to try and clamp down over the hedgehog, to prevent what he knew was coming, and to-if he was lucky-snuff the bright blue flame that was the hedgehog's life. Not happening. The instant the second hand touched the hedgehog; there was a brilliant gold explosion and the robot's hands fell apart. Sonic paused to suck in air happily-that robot had a tight grip-before shooting forward, blasting through the center of the battle suit and continuing onward.

Eggman smiled inwardly. All going according to plan. He forced his voice to sound scared and he hastily pushed another button. He needed the hedgehog in a specific place, and he needed to get there first as well. "Uh oh, time to go!" the robot around him fell apart as his hovercraft shot forward, along the very corridor he had caught the hedgehog in.

"Yo! Egghead! Get back here!" Sonic followed not a second later, not giving the numerous doors that slammed shut in front of him a second thought as he rammed through them in brilliant gold explosion after brilliant gold explosion. The craft burst into smoke and flames the second the two combatants had left it, Eggman still in front. Though only by a few seconds. He raced towards the strangest shaped satellite in his fleet, and couldn't decide if he was happy or sad that the gold hedgehog was currently occupied playing a deadly game of hopscotch with the remainder of his fleet.

He shot into the nearest entrance and up the shaft. A slight steering miscalculation sent the craft gently nudging the side, and catapulted the round man out and onto the floor. Where he bounced. Yes, he bounced. Not seconds later, the golden hedgehog-shaped superhero plowed through the floor, where red eyes gleamed with a slightly amused twinkle. Eggman immediately dropped to his knees pleadingly as the hedgehog started to land. "S-Sonic! I-I'm sorry! R-Really! L-Look, go easy on me! I'll turn over a new leaf, I swear! Just give me a chance!" At these last words, he bent over and clasped his hands together over his head.

Sonic landed and gave the man a haughty look. When he spoke, amusement dripped off his voice, like this was all a game, a way to keep his mind entertained, though the fresh nick in his ear didn't reinforce that fact. "Well, this is new. Showing remorse, Eggman? If ya played nice, I wouldn't have to break all your toys."

The hedgehog was far too busy gloating to notice as Eggman began to slowly pull an item from his pocket. At least, until it was too late. The man's thumb slammed down on the glowing red button as he proudly proclaimed: "Gotcha!"

Sonic glanced around in shock and surprise as metal pillars rose from the floor around him and unfolded from the ceiling. "Wha-?" He whirled as they rose quickly, and he shot to the side, the alarm bells in his head going off at an annoying loud rate. Too late. Strange beams of energy surrounded him, holding him in place while keeping him slightly held off the ground. He ground his teeth and struggled as a pillar under Eggman began to rise, taking the man with it as he began to cackle happily. By the time Sonic really noticed his change in height, the thought was swept from his mind as strange purple electricity crackled from the beams on the ceiling, and shot towards him. He screamed in shock and pain as a strange feeling accompanied it. A strange sucking feeling, like the beams were trying to take something. He ground his teeth as he realized what. He struggled to keep it and closed his eyes, shaking slightly, then the pressure became overwhelming and he screeched again as the chaos energy was torn from him, and the emeralds reappeared in a circle around him even as the gold faded from his quills.

Eggman smiled as the faint sound of machinery came from below them. This was just too good to be true! His plan was going perfectly, and-to add to the bargain-he got to watch his nemesis in pain! The color slowly began fading from the emeralds as Sonic turned with a slightly pleading look to Eggman as another fresh wave of pain rippled over and sent him into screaming agony again.

Eggman smiled as another-more distant-sound of electricity joined the closer one, and he stepped into a nearby control room. He laughed and gleefully rubbed his hands together in anticipation. "Ho ho ho ho ho! Oh, I've waited a long time for this!" he grinned and raised a hand high before bringing it down dramatically on a button flashing with the seven colors of the emeralds. "Fire!" He watched happily as his wish obeyed, and a purple beam shot from the strange satellite before crashing down to earth, the shockwave scattering visible clouds. He returned his attention back to the hedgehog, who had by then dropped to the floor, shivering visibly as the electricity continued to crackle, though not nearly as strong, then returned his attention to the shattering planet.

If he was being honest with himself, Sonic would say that all he really wanted right now was to curl up and stay there until he no longer felt like he was about to die. Of course, he was far too stubborn for that, and he struggled to stand. He barely heard the awed: "Whooa" from Eggman as he managed to get to his hands and knees. He groaned and was sent back to the floor as something seemed to smack head-on into his chest. When he glanced down, there was nothing there, but a strange feeling came with it, and more pain. But it wasn't the pain of electricity, no, it seemed to come from inside. He groaned as he felt like he was going to explode, before his arms swelled painfully and dark blue fur burst from the originally tan arms. His voice deepened as he groaned in pain as his hands grew too large for the gloves, and giant hands and claws tore them to shreds. His ears shifted to a pointier, more triangular shape, and his stub tail stretched and lengthened into a bushy one he could move freely. His teeth were pulled into vicious fangs, and he gave a final howl as the pain subsided, and the electricity faded. The seven emeralds-now a motley collection of dull greys- fell to the ground with a clatter and Sonic gave a wheezy gasp of relief before his hands slid from under him and his chest hit the floor, where he struggled to calm his rapidly beating heart and trying to forget the ordeal.

Behind him, Eggman was in full gloating glory, forgetting the hedgehog was there. "Success! A brilliant success! It's just as the Gaia Manuscripts foretold! The entity that was sealed within the planet has awakened. Now I just need to harness its power. Eggman Land will finally come to be!" He launched into a barrage of victorious laughter, during which Sonic stood and glanced at the window. His jaw dropped and he whimpered slightly. He was not a hedgehog-that was for sure. Yes, he had retained his quills, though they looked…furrier. His eyes glanced down at his hands, and he found that they had grown to around twice their original size, and were tipped with deadly claws. He glanced up again, forcing his gaze away from the teeth that poked out of the corners of his mouth, and focusing on the planet outside. His fur immediately spiked up and he snarled when he looked at the planet. Questions raced through his head as he stared with a horrified fascination. How could it still function? Was everyone down there safe? And-most importantly-how the heck was he going to fix this?

He whirled on the man behind him with a snarl. "You've really gone and done it this time! How do you plan on ruling a planet when it's been made into seven?!"

Eggman glanced down at the deeper voice, trying to place it. What he found was a large wolf-like creature in the place where Sonic had been. For a second, he stared, dumbfounded, at his enemy. This…this was not in the plans! He shook it off and answered. "Ah, S-Sonic. That's a good look for you. Festive!" The man slammed his hands down on the control panel, making Sonic's now hypersensitive ears twitch and he jumped slightly. "So long, Friend." The word was said with mocking contempt, and Sonic's eyes narrowed at this. Before he had the chance to respond, a glass wall had slid down around Eggman and he pressed a button.

Sonic glanced around at a sucking sound, and his eyes widened as the glass wall behind him lifted. He fell backwards and managed to catch a tiny ledge with his newly gained claws. He struggled to pull himself back up into the room, struggling to fight the tug of space. But his encounter with the machine had left him drained and weak, and he couldn't hold on for long. He lost his grip and fell with lifeless Chaos emeralds down to the planet.

Well, there's chapter one. yes, this is supposed to be almost exactly like the cutscenes and game. Yes, I added some dialogue to it. Yes, it might not flow well. Yes, it is supposed to have some humor in it.

Hope you enjoyed, and leave a review if you did!
