Hello folks! This is my first attempt at making a Fanfiction story. So don't kill me if its bad. I had the concept of this story down for a long time and really want put it down. So here it goes. Leave feedback about the story so I can improve.

Chapter 1: Crossover

Earth Dimension

A human boy was running at the speed of sound across the grassy terrain of a forest. For two years, he had been on the run from the government due to the power he possesses. His real name was Bailey To, but most people infamously call him the Shapeshifter. Bailey continued to run until the police sirens behind him got quieter and quieter. When it became completely silent, he stopped in place and fell down to the ground.

"I finally lost them."

He got from the ground and continued walking deep into the forest to get further away from the city and to find a safe place to sleep. He was lonely and hated the life he had now. Even more then the life he previously had with just sitting in the house playing Xbox all day and not hanging out with friends because he doesn't have any. As he walked past several trees and wildlife, he stomped onto a pond.

"Water?! Finally!"

He ran over and stuck his hands in the water and drank. He had been running from the government all day trying to stay free, but how is this free? To Bailey this was basically torture. He was tired of running and wanted to disappear. Somehow, someway, he got his wish. A weird sound in the distance made the human boy look up from the pond. A bright purple vortex appeared in the face of the Shapeshifter blinding him in the process. Bailey covered his eyes as the vortex sucked him into the portal leading him to an unknown world.

Mobius Dimension

Sonic the Hedgehog was racing across Green Hill Zone again. Going on his daily runs across Mobius and having a blast as always. The sun was shining over the vast forest of Green Hill.

"Man what a day to be alive! The sun is shining and the birds are chirping as always. Nothing can ruin this day."

However Sonic didn't realize that something was going to happen. As his wrist communicator started beeping to get his attention. When Sonic answered it, his best friend Tails popped up with an urgent message. Sonic answered with:

"Hey Tails! What's going on? Need help something?"

"Not with me specifically Sonic, its Knuckles and Shade. They're defending the Master Emerald from Eggman. He's trying to steal the gem again for his evil plans and he has a massive army attacking right now."

"Ugh of course we wouldn't go very long with Egghead keeping quiet. Alright, I'll head on over to your place and we'll head to Angel Island in the Tornado.

"Sounds good Sonic. I'll tell Knuckles and Shade to hold out a bit longer and that we're coming to help."

Sonic then hit hang up on his wrist communicator and raced off to Tails' workshop. When he got there, he saw Tails making final preparations on the Tornado before liftoff. He saw Sonic heading towards him.

"Come on Sonic! We got to get to Angel Island before Eggman's army takes the Master Emerald."

Sonic then hoped on the Tornado and he and Tails flew out of the workshop garage to help Knuckles and Shade.

Angel Island

Knuckles and Shade were originally relaxing on the Master Emerald shrine before Eggman attacked. They were holding off their robots, but were breaking down as Eggman's army was starting to overwhelm them. Knuckles bent down on one knee after a robot smacked him.

"Ugh! Damn! Where is Sonic and Tails? They should be here by now."

Shade took down a few robots and then helped Knuckles get up.

"I don't know. But we have to hold. The Master Emerald is depending on us."

Elsewhere on Angel Island, a purple vortex appeared and dropped a human boy onto the grassy surface. The human rubbed his head and slowly rose from the ground.

"Ugh. Where am I? Man that flash is giving me a headache."

Bailey slowly walked forward and flung his arms and flew backwards in time before he walked off the edge.

"What the hell what is this place? You can see the clouds near you in the distance and you can't see the bottom! Are I on a floating island?"

Bailey was right. The clouds on the strange island weren't too far in the distance and if you looked off the edge you can see the ocean down below. There was no land below and it made Bailey come to the conclusion that he was on a floating island.

"Has this place been around the entire time? I would've heard of this place by now."

Bailey continuously looked around the island searching for any residents. All he saw were animals such as rabbits, birds, and other creatures.

"I should look for someone and find out where I am. It's a risk I'll have to take."

Bailey then heard an explosion in the distance coming from deep in the island. He ran over in the direction of the sound to see what was going on. After 20 minutes of flying, Sonic and Tails reached Angel Island in time to help Knuckles and Shade. Sonic immediately jumped off the Tornado to help his friends. He landed on the ground and spin-dashed multiple robots on all sides. He then slid in front of Knuckles and Shade.

"About time you showed up." Knuckles growled.

"What's wrong Knucklehead? Can't you handle a few Eggman robots?" Sonic said while grinning.

"Enough bickering you two." Shade roared. "We still have Eggman to deal with."

Speaking of Eggman, he finally joined in on the fighting with a massive robot of his own.

"Ho ho ho!" Eggman shouted. "Miss me you three?"

"Eggman." Knuckles said as he grinded his teeth. "Back off the Master Emerald."

"Oh why would I? It would be a great tool to use in my evil plans. Now step aside or be crushed."

"You'll have to get through us if you want the emerald." Sonic responded.

"Well alright then, if you insist on getting on my way, I'll just have to pummel you all into the ground."

Before Eggman could attack, an energy blast hit his robot in the back. Tails managed to reach the shrine in time.

"You'll regret that fox boy." Eggman growled.

Tails flew over towards Sonic, Knuckles, and Shade. Standing in a fighting position, he was ready to fight alongside his friends. Somewhere close by, Bailey was watching in the distance as the four heroes of Mobius fought Eggman. He was shocked at who the individuals were and their incredible powers. He figured that they were protecting a valuable object as he observed the shrine. Figuring the four animals were the good guys, he wanted to find some way to help them, but he held back as he didn't know if they react to his powers the way others have reacted. He figured he would hide his powers unless these four could be trusted. The opportunity to help the Mobians came when Knuckles and Shade were thrown back from Eggman's robot and Sonic and Tails were knocked on the floor. Bailey saw this and had to do something quick. He looked around for something to throw. Something that could distract Eggman and give the Mobians an advantage. He saw a rock on the ground, picked it up, ran out from the bush he was hiding in and threw the rock towards Eggman's cockpit. The rock hit Eggman in the head and he put his hand on the point of impact.

"Argh! Who dares disrupt my attempts at world domination?!" Eggman yelled.

"Over here fatso!" Bailey screamed.

Eggman looked over and saw the human in the distance.

"How dare you attack me boy. Now you will pay the price!."

Before Eggman could attack Bailey, Sonic sped up and spin-dashed the back of Eggman's robot. Tails followed up by throwing a homemade bomb on the massive robot. Knuckles and Shade then combed a series of power combos to the robot's legs, slicing them off the process. Eggman's special robot was defeated and he was forced to retreat.

"You're going to pay for this!" Eggman screamed as he flew away in retreat.

"Whew. Glad that's over now." Sonic said as he sat down.

"Agreed." Shade replied.

Knuckles looked over and saw Bailey staring at them. He approached Bailey and examined him. Confused he was. As he had never seen a human on Angel Island.

"You were the one who hit Eggman in the head with a rock right?"

"Yes… that was me." Bailey said still in shock that the echidna could speak and had immense power.

Tails spoke up. "Yeah you gave us a good distraction and we were able to finish off Eggman. That was very brave of you."

"Th…thank you." Bailey slowly spoke.

Sonic rose from the ground and dusted himself off.

"Hm…you're human. On Angel Island." Sonic spoke.

Shade broke her silence. "This is very strange. A human somehow appears on this island. Who are you foreign traveler and what is your name?"

Bailey was incredibly nervous as he has not had conservation like this in a long time. He looked down thinking of what to say. He still did not know where he was but figured that this was an entirely different place from what he's known. Talking animals with powers like him. He still wanted to be cautious in case they were some sort of spies from secret experiments of his government.

"My name… is Bailey." He finally spoke. "And I have never heard of this Angel Island."

Pretty long chapter I must say especially for a first chapter. Weird place to end though, but I'll update the next chapter soon. How'd I do guys? Please leave feedback. I'm really excited to start this story and really want this to be a good story.
