Lakewood, Washington, 10:00 pm

Mchord Air Base sat silent, the full moon shining down on it. A Hercules airplane sat on the runway. A figure was walking towards it, carrying a duffle bag and wearing a black cloak he stopped in front of the ramp. There were two of the pilots waiting for him. "Uh…Hello, you must be-'' "No time for introductions, lets go.'' the figure walked inside the plane. "Well, very intriguing, get his bike.'' the pilot said to the other as he walked inside the plane. The figure was sitting on one of the seats, he watched the pilot bring his motorcycle onboard, making sure he didn't damage it. "Alright boys, your cleared for takeoff.'' the command tower operator said "Roget that, taking off.'' the pilot responded. The pilot steered the Hercules steady, he accelerated the speed, and in no time they were up and flying to their destination.

London, England, 12:00 pm

Flying through the night sky with stars spread across the sky, they were over their destination. "Alright sir, we're opening the door.'' the pilot called. The ramp opened up, the figure strapped his bag on his back and he got on his motorcycle. "What're you doing? Your jumping out of a plane on a bike?'' the pilot said confusedly "I like taking risks.'' the figure replied. He revved the engine and did a wheelie out of the airplane. Now in a freefall, the figure took out the green chaos emerald. "Chaos control!'' he shouted. He teleported on top of the London bridge. The figure got off his bike, his two way radio ringed. He reached in his bag and pulled it out. He raised the antenna, "Yes?'' he answered "Well it's been a while, shadow.'' a voice replied. Shadow sighed and lowered his hood, "Very funny general.'' shadow replied "Listen, a quick apology about awhile back-'' "No need, besides you just threatened to kill someone and nearly shot me, not too surprising in my life." replied shadow.

"Thank you, now we received images from our satellites that there was a sighing of metal sonic, find him and-'' "Take him out?'' shadow finished his sentence "Your smart shadow, yes exactly, Richards out.'' he hung up. Shadow sighed, "Generals these days.'' he put his hood back on and hopped on his motorcycle. He jumped his bike onto the support beam of the bridge and rode down it. He steered himself onto the traffic filled bridge. Minutes later he got out of heavy traffic and into a quiet part of the city. He looked up and saw the clock tower, he teleported onto a roof. He stepped off his bike and he used chaos control to make it disappear. "So far no sign of him.'' shadow mumbled. Suddenly he was grabbed from behind, it was metal sonic. Metal flew up around in the air, shadow turned himself toward the villain and punched him.

Metal sent a punch back, but shadow grabbed his fist and kneed him in the stomach. Shadow pushed metal sonic downwards into the roof of a building. Shadow threw his cloak off, knowing he won't be needing it. Metal charged first, shadow dodged and kicked metal in the back of the head tossing him threw a window of a lower building. Metal came smashing through the wall of the house at shadow. He tackled the hedgehog, both punched each other senselessly while in the air. Metal flew up to the clock tower and flung shadow through one end, shattering it and he came out the other end. Shadow teleported himself to safety on top of a building. Shadow looked up to see metal sonic crash down on him sending both crashing through each floor of the building. Finally both slammed to the bottom floor, sending out a wave of dust and dirt coming out from the windows. Metal sonic was thrown through the concrete wall and crashed into the side of a car. A volley of chaos spears out of the building and hit metal where he sat. It caused the car to explode into flames.

Shadow jumped out onto the empty street. A cluster of missiles came straight out of the smoke, shadow put his arms up in defense as he was thrown against a wall and pummeled by the rockets. Shadow teleported behind metal and grabbed him by the wrist. Shadow smashed metal into the hood of another parked car. Shadow dove at metal with his foot aimed at his head. Metal at the last second struck shadow in the stomach with his foot. Metal kicked him in the side of his head with his other foot, flinging shadow across the ground. Shadow saw metal charging at him, shadow got up and drove his fist through metals stomach and out the other end. Shadow took his arm out and watched metal stumble backwards then collapsed to the ground. Shadow rubbed his head, "Man that hurt.'' he walked away. Shadow teleported onto the roof of a building where a helicopter was waiting for him. He hopped in and it lifted off back to Mchord Air Base, but he's going to have one rude welcoming waiting for him.

Shadow saw they were about to fly over the base when suddenly a missile hit the middle of the helicopter. It spun out of control, shadow held onto something as it descended to the base's runway. With a loud bang it crashed into the ground and the screeching metal of the helicopter rang loudly. Shadow reached his hand up and grabbed the outside of the helicopter. He crawled out of the passenger seat and flopped onto the ground. He was on all fours coughing to breath. Shadow looked up, his eyes widened. Scattered around the air base were dozens of army soldiers, all dead. The jumbo jets were split in half or fully destroyed, burning vehicles laid around the base. Shadow limped away from the crash site, he then felt a sharp pain in his back. It was a dart, shadow's eyes slowly started to close. The last glimpse he saw was Metal Shadow walking towards him with two MP5's in his hands.

2 Hours Later

Shadow started to stir, he sat up. "Oh my head.'' he rubbed it. Then he noticed three apache helicopters watching him with their spotlights on him. Then SWAT members moved in, their guns drawn. "Drop the guns!'' one yelled. Shadow noticed in both his hands were MP5's. "No'' he whispered "Get down NOW!'' one shouted aiming his gun at him. Shadow not wanting to cause any more havoc, tossed the guns away and put his hands behind his back. They put handcuffs on him and dragged him to a prison bus waiting outside the base. Shadow, with hate filled in his body, vowed to get revenge, by any means necessary.

3 Months Later

Shadow was given a ragged ripped grey cloak, they were crossing a long bridge to an island, the prison shadow will spending his whole life at. The bus stopped in front of the doors leading inside to the prison. The bus stopped in front of the courtyard outside of the main prison building. Shadow stepped out with two armed officers walking along side him. All the prisoners looked at him, and started laughing because his "size". Shadow was sent into the prison, and to the warden's office. Shadow was sent inside, there was a middle aged man with brown hair and a brown mustache. "This must be the one.'' he got up.

Shadow was glaring at him, "Killing your allies…very evil don't you think?'' he said. "Warden Johnson, now from what I've seen, your not normal.'' he said looking at shadow's record "Aren't we all?'' shadow spoke up "An attitude, haven't seen that much around here.'' "You haven't seen nothing yet.'' shadow changed his tone "Very brave of you, you'd better watch yourself, being so such short of a prisoner can result in being squashed like a bug, get him out of my sight.'' the warden waved his hand and returned to his seat. A few hours later shadow was in the lunch room eating…alone. Most of the prisoners looked at him time to time and joked about it, but shadow didn't care, but if he had the chance he'd know what to do. Then a group of bald thugs walked over to him, one of them was taller and a tattoo of a dragon going down his neck. "Well well well, look at this, it must be the most smallest prisoner ever.'' he spoke out. Shadow continued eating his food, ignoring them. "Killing and ravaging a whole base of army soldiers, that's what your in here for?''. This is when the prisoners around were talking about what he said.

"Answer me scumbag!'' the prisoner yelled. Shadow remained silent, "Hmmm, no wonder you don't talk, do you have any friends, maybe one that's a girl?'' the prisoner whispered next to him. Shadow was tightening his fists at this point. "No matter, she probably thinks you're a piece of shit anyway.'' Shadow was on the brinking point, shadow's cloak started to rise slowly, he wanted to take all his anger out right now. "I bet she's a bit-'' Shadow gave a punch to his stomach throwing the prisoner across the ground and slammed into a table. Shadow grabbed another and slammed him head first into the table he was sitting at. The prisoner that threatened him came at him, but shadow jumped onto the table facing him. The prisoner threw a punch, but shadow grabbed it. "Tell me, do you really wanna' fight me?'' shadow lowered his hood. His eyes completely glowing red, shadow gritted his teeth, he grabbed the lowlife by the neck and started squeezing the life out of him. "Let him go.'' the warden said from behind. Shadow turned his head at him, shadow dropped him, as he started coughing madly. Shadow put his hood back up and followed the warden back to his office.

"You think you can do whatever you want don't you?'' the warden said "That's the idea.'' shadow replied "Hmm, very brave, I've been looking over your records, you have some skill.'' Johnson told him "You don't know the half of it.'' shadow said "Would you like to leave this place?'' he asked "What are you proposing?'' shadow responded darkly "We have a special sport here, as you saw, there is what looks like a track on the island.'' Shadow raised an eyebrow, "Win two races, and you're free.'' the warden sat back in his chair, smiling. Shadow looked to his right, looking at a part of the track. "So what do you say?'' Johnson asked. Shadow looked straight at him, "No'' he answered. Johnson's expression changed to an angry one, "I'm given you a chance, race and you will be set free, if you live.'' "I don't do things for others entertainment.'' shadow said angrily. The guard behind shadow lunged at him with a nightstick, shadow grabbed it without looking, he then tossed the guard out the window behind Johnson. Shadow stepped toward his desk, "What makes you think I'll do it?'' shadow said "You seem really desperate, so here's your chance.'' Shadow stepped away from his desk, "Fine, I'll do it.'' shadow gave in.

At a large warehouse in the prison, shadow and the warden were walking throughout it. "Here are where the cars are tuned up and fixed, your station is up ahead.'' Johnson informed him. It was a small box like work station, we'll have a car for you and-'' Johnson stopped when he saw shadow looking at an old motorcycle. "Cars aren't my strong point, I'll take this.'' shadow grabbed the handles and pulled it over to his work spot. "You do realize that you could be easily killed on this.'' Johnson told "We'll see about that.'' shadow replied, and so he began to armor up his motorcycle.

The next day, the warden arrived at Shadow's workstation. The motorcycle was covered in steel, pieces of steel overlapped on the front wheel and back wheel, along the top of the steel plates were spikes. Attached to the front wheels on the left and right were mini-guns, in front of the handle bars was a small rocket launcher, with the push of a button would fire a rocket. "Wow, very amazing shadow.'' the warden said. Shadow turned to him, "Is the race today?'' he asked putting away his tools. "Yes, it actually begins in a few minutes, get your bike at the starting line.'' the warden walked off to the control room.'' Shadow put his cloak and put the hood over his head. Shadow drove the motorcycle outside with the other vehicles. Shadow looked at his two holsters on the left and right sides of his bike, in both was an MP5. The drivers pointed and laughed at the sight of a bike on the track. The warden watched the screens showing the racers.

Shadow looked at the other cars, covered with armor plating and mounted with high tech weapons, but shadow wasn't intimidated. The racers got in their cars, each one determined to win at any cost. Shadow noticed the guy next him was the one that threatened him earlier. Shadow ignored it, the engines of the cars throttled up. The light changed to yellow, shadow narrowed his eyes, then green. Shadow did a wheelie off the starting line already in the lead. The cars trailed behind him, shadow saw an opposing driver right next to him. The driver laughed at him, shadow got behind him, shadow tossed a C4 charge on the back of his car. Shadow rode out in front of him, "Laugh at this.'' shadow pressed the detonator.

The back of the car exploded in flames as it was thrown forward sliding across the ground. Shadow made a sharp turn into a warehouse, a driver was on his left and one on his right. Shadow shook his head, both cars drove at him attempting to squeeze him. Shadow slowed down and watched both cars smack into each other, shadow fired his rocket launcher. The rocket exploded between the two and sent them crashing into the brick wall in front.

Shadow drove out of the warehouse, suddenly bullets shot at him. The prisoner he encountered was right behind him, the rival flew past him and stopped in front of him. "Eat this!'' he shouted pressing a button. From the back of the car was a wave of flames. It covered shadow, finally the flames died out. His cloak was completely burned off, his identity revealed. "What in the world is he?'' the warden watched the screen. Shadow jumped off his bike and fired a barrage of chaos spears on the car. Most made their mark, then shadow landed on his hood. "Chaos'' "Oh sh-'' the prisoner said "BLAST!'' a giant red dome wiped across the whole island. The prison complex completely leveled, the warden got up out of the rubble limping. A piece of metal was in his leg, causing him to collapse onto the ground in pain. Shadow stopped his bike next to him and got off. "You'll…p-pay for t-this.'' Johnson stuttered while the pain exceeded "Just so you know, no one tells me what to do.'' shadow said "J-Just who are you?'' Johnson asked "I'm the Ultimate Life Form: Shadow The Hedgehog!'' he told him. "Y-You can't e-escape.'' Johnson muttered "At least you won't have to see me do so.'' shadow walked back to his bike. "Oh, and here you go.'' shadow tossed a C4 charge in front of his face. Shadow accelerated his bike toward the long bridge, he broke through the gates. He held up the detonator and pressed it, there was only an explosion and a very loud scream of death.

Amazon Jungle, 3:00 pm

"For the last time! Just stop!'' a voice yelled "Why? I'm so bored!'' a small rabbit complained "Just listen to me and stop.'' a anthropomorphic dog told him. The rabbit was the pesky and annoying Mr. Whiskers, the dog was Brandy Harrington. She sighed and sat in her chair, "What's wrong this time?'' asked whiskers "It's just-'' "Oh, Oh! Wait I know, you miss sonic don't you?'' "Shut up whiskers! Why can't you let me talk!'' she exclaimed "See? It just proves my point even more.'' whiskers said "Grr, your so dead!'' she got up, but that was until sonic crashed through the house and out the back, sliding across the dirt. Sonic leaped back inside, "Hey brandy!'' he jumped back out of the house. Both looked to see sonic fighting Metal Knuckles. "You need any help?'' brandy called "Nope, I'm alright!'' sonic ducked one of metal's punches.

Sonic kicked him across the face and then spin dashed him right into a tree. Sonic slid down the tree and stood in his stance. Metal came back, sonic easily dodged it, but metal swerved back quickly and punched sonic in the face. Sonic got back on his feet to stop himself, he spun in a ball and hit metal head on. Metal slammed against the tree holding the tree house up, sonic charged at him again. Metal grabbed sonic and smashed him against the tree, the shaking caused brandy to fall off! She screamed as she headed for the ground, sonic elbowed metal in the head and got free. Sonic leaped up and grabbed brandy. "You alright?'' he asked "Yeah, thanks.'' she said. Sonic then put her back on her feet, but he was tackled by metal already. Sonic rapidly punched him in the face, metal kneed him in the stomach. Sonic was sent flying through the air, he landed on a branch. Metal came flying at him, sonic jumped to another branch as metal splintered through the other. Sonic snapped the branch off and pushed himself from the trunk of tree towards metal.

Sonic swung the branch across metals head. Metal crashed through a row of trees, all snapped and fell on him. Sonic landed in front of the carnage, he tossed the branch away. Suddenly hovered out of the branches and charged at sonic. Sonic sent a powerful punch into metals core power source. Sonic's hand stuck out the other end, "Eugh!'' sonic took his hand out. A gape in metals chest was left as he collapsed backwards to the ground, defeated. "Once again the mighty hedgehog wins again!'' whiskers said in a deep voice, brandy rolled her eyes.

"This isn't right, either this one isn't real or I'm just stronger!'' sonic smirked, brandy just shook her head. "Why was he after you anyway?'' brandy asked him "Don't know, but I did buy this TV from New York!'' sonic ran to a bush and took out a medium sized television. "Sweet!!!'' whiskers shouted. The three went back to the tree house and set the TV up. "Let's see what's on.'' sonic turned it on. The news came up, BREAKING NEWS was written on the bottom. "The most secure penitentiary has been completely destroyed yesterday.'' the male reporter said "Wow something already interesting.'' sonic said "This video was found by a tourist who was just walking on the boardwalk of the city when he saw it.'' he finished. A giant red dome exploded then vanished in the night time sky. "That's very interesting.'' sonic rubbed his chin.

New York City, 6:00 pm

Shadow was standing on top of a skyscraper with his arms crossed. "Man, what am I suppose to do now?'' he asked himself "Where am I suppose to go?'' he said. A bang came from behind him, he turned around and saw a hand with sharp claws sticking out of the ground. The other fist punched through, it pulled itself on top of the roof. Shadow widened his eyes, it was WereSonic. "What're you doing here Sonic?'' shadow asked. Without answering he charged at him and tackled him off the building. Both hit each other as they were spinning in a freefall. Shadow kicked him in the stomach with both his feet as. WereSonic crashed through the wall and rammed through a couple walls.

Shadow stopped in front of the hole, debris covered across the floor. Shadow jumped into the spot WereSonic crashed, but he wasn't there. Shadow stood back normally, "Where is he?'' he whispered. Then WereSonic grabbed him by the arm and slammed him sideways into a wall, then into another. He finished by throwing shadow up through the roof and bouncing against the ceiling. WereSonic jumped up at him, but shadow drove his feet into WereSonic's face throwing him down two more levels down.

Shadow landed on the floor WereSonic was. He marched toward him, and grabbed him. WereSonic awoken and punched shadow further into the building, shadow came to a stop and saw Weresonic running at him. Shadow swung his leg at his legs and he fell onto the ground. Shadow grabbed his ankle and threw him onto the floor above them. Shadow teleported in front of him and fired chaos spears at him. It caused fires to break out, the sprinklers from the ceiling sprayed water all over the area. Shadow picked WereSonic by his ankle and threw him hard. Shadow used chaos control and he had a M72 rocket launcher in his grasp. He fired the rocket, WereSonic still being thrown walls was hit by the rocket and finally crashed out of the building and smashed into a car on a busy street. Shadow sped out of the gap in the building and landed onto the street.

He jumped forwards dodging a car, WereSonic punched him back and through a rectangular glass window. WereSonic leaped inside the window, shadow was surrounded by smoke. WereSonic charged without care, shadow growled. "Chaos BLAST!'' A red dome of energy exploded out of the building. The windows above shattered as it went throughout the building. Shadow walked out of the building holding his head. "Ugh, where'd he go?'' shadow looked around. He saw WereSonic scaling up and around the side of a building. Sirens of police cars rang, "Forget it, I'm outta' here.'' he sped up a building. When he got to the top, he looked at the sun setting. "Time to pay Sonic a little visit.'' he said angrily.

Amazon Jungle, 8:00 am

Sonic, with Brandy and Mr. Whiskers were watching TV. "Turn something else on.'' whiskers said "Why? I bet you can't find anything.'' sonic snapped. "Just let me see it.'' whiskers whined "Fine" sonic tossed him the remote. Whiskers smiled and change the channel, right when he did the wall and TV exploded. "What was that!?'' sonic exclaimed "I don't know! But the TV is gone!'' whiskers cried. Hovering into the house was Shadow. Sonic widened his eyes, "Uh, hey shadow what's up?'' sonic greeted "Your what's up.'' he fired a chaos spear at his feet throwing him out of the house and into the air. Sonic saw shadow coming at him, sonic spin dashed straight into him until he crashed into the ground. Sonic jumped back, "What's wrong with you?'' sonic shouted "Oh you know faker.'' shadow teleported behind him and kicked him in the head. Sonic fell face forwards on the ground, shadow dived at him with his foot aimed for his head. Sonic rolled out of the way and gave shadow an uppercut. Shadow crashed onto a tree branch and snapped through it. Sonic ran and grabbed him by the wrist, sonic threw him against the trunk of a tree. Sonic threw another punch at him, but shadow grabbed it. Sonic threw his other at him, shadow grabbed that one as well. "Why are you attacking me?'' sonic said "Because, you attacked me, you freak!'' shadow shouted and pushed him all the way against the dirt.

"Freak? He thinks I attacked him as WereSonic? Oh no that means…'' sonic came back to reality and dodged three chaos spears. "Shadow Stop!'' he jumped over him "I didn't attack you, it was Eggman's new robot!'' sonic said. Shadow stopped a few feet in front of him, "A new robot?'' he said "Yes, it's disguised with a identical outside, but under the disguise is a metal!'' sonic explained "Why should I believe you?'' shadow asked "Because I didn't no where you were? How could I have found you and how would I get there?'' sonic answered "Hmm really didn't think about that.'' shadow confessed, sonic slapped himself on the forehead.

"So, exactly what are we waiting here for?'' shadow asked "We really don't know, but once something comes up we'll be ready.'' sonic sat back in his chair. Shadow walked over to his duffle bag when he heard something. Shadow took out his two way radio. "Hello?'' he answered "Shadow, I've heard what happened.'' it was General Richards "Listen I didn't do it!'' shadow exclaimed "Really, I had fingerprint tests on the MP5's you had, they matched with yours.'' Richards told him "There's a situation, we have a large energy source heading towards Beijing, the Olympics just started and whatever it is, its heading for the stadium.'' he finished "Why are you telling me?'' asked shadow "Because you better not dare interfere, my men will handle it, and shadow stay out of it.'' he hung up. Shadow threw the phone onto the ground angrily. "Whoa, what's wrong with you?'' sonic asked "I'm heading out, I'll be back.'' shadow said. He reached in his bag and took out his black cloak, he threw the hood over his head. He threw his bag over his shoulder. He opened the door and sped through the jungle. With a new mission on hand, will shadow know what's coming? Will he be ready? Read on to find out.

A/N: WOO! First chapter! The transitions at the beginning are crazy, I know. I'll say that not only all the characters from my previous stories will be in here, but there new characters will also be introduced! Virtual cookie to who guesses right where the race scene came from, XD.
