"Agent Shadow, I have an assignment for you," said Commander Abraham Tower as Shadow walked into the command room.

"What is it, sir?" asked Shadow as the twin doors closed behind him. Images flashed through Shadow's mind as he asked that question. Images on how he got here in the first place.

Shadow the Hedgehog was created by Professor Gerald Robotnik to be the ultimate lifeform, and the cure for Neuro-Immuno Deficiency Syndrome, or NIDS, that infected his grandaughter Maria. But the Guardian Units of the Nation, or G.U.N for short, saw Shadow as a weapon and wanted to destroy him. Knowing this, Robotnik told Maria to take Shadow to an escape capsule so that Shadow would be out of G.U.N's reach. In the process of doing this, Maria was shot by one of the G.U.N agents, making her death that much quicker. In her last moments alive, Maria launched the capsule with Shadow in it to earth, saving him. When Shadow was reawakened by Gerald's grandson, Doctor Ivo "Eggman" Robotnik, he promised that he would destroy all humanity for the death of Maria Rovotnik. In the end, it was Shadow who helped save the earth alongside Sonic the Hedgehog. At the end of it all, Shadow plumeted to the earth, making everyone think that he was dead. Little did everyone know that Eggman later searched for Shadow's body and put him in a capsule, giving Shadow the long rest that he needed.

A few months later, Shadow was discovered by Rouge the Bat, who was sneaking around Eggmans. Shadow realized at that moment that he had no idea who he was or where he came from. So he, along with Rouge and the robot E-123 Omega, chased after Eggman in search for answers about his past. In the end of his search, Shadow discovered nothing.

Three months later, Shadow confronted an alien race called the Black Aliens, lead by their leader Black Doom. Black Doom confronted Shadow, telling him that he knew about Shadows past and promised to tell him everything about it if he helped the Black Aliens collect all seven chaos emeralds. Once he collected the seven chaos emeralds, Black Doom betrayed Shadow and tried to stop him, but Shadow resist Black Doom's powers and proceeded to chase him. Once catching up to him, Shadow proceeded to ask Black Doom questions about his past. Black Doom started to lie, but a video behind him started to play that had both Professor Gerald Robotnik and Maria Robotnik in it, telling him about why he was created. At that moment, Shadow's memories started to return and he remembered why he was created. Black Doom transformed into his ultimate form, Devil Doom, and he tried to stall Shadow long enough for the Black Comet to destroy the earth. Shadow used the seven chaos emeralds to transform into Super Shadow and fought Devil Doom, defeating him. Shadow then used Chaos Control to move the Black Comet into outer space, right in front of the ARK, the weapon that he had helped to stop from destroying the earth several months in the past. Shadow then warped himself into the control room of the ARK and fired the main canon, destroying the Black Comet. After that, Shadow joined Rouge as an agent of G.U.N, doing missions that other soldiers could not do.

Shadow snapped back into the present as Tower started to speak to him.

"We have received reports from one of our agents that a chaos emerald has been found somewhere at Mount Everest. The last time that Super Sonic transformed back into normal Sonic, the green chaos emerald flew to Washington. Our men found it and tried to retrieve it."

"So whats the problem?" Shadow asked.

"We were not the only ones to find the chaos emerald. When our men tried to grab it, a enemy attacked them and tried to prevent them from reaching it. We..." Tower looked down at the ground, as if in pain from what he was about to say, "...lost their signal." Tower turned to one of his men. "Play the video."

"Yes sir!" The soldier turned and started to type on his keyboard. As he did, a monitor lowered from the ceiling and the screen lit up. Tower turned back to Shadow and started to speak.

"Before all of our men were wiped out, one of them managed to send us a video of the events that happened." Both Tower and Shadow looked at the screen as a picture started to show up. The first thing that they saw was an explosion being set off and snow flying all over the place, as well as G.U.N soldiers.

"Mayday! Mayday! An unknown enemy is attacking our forces! I repeat, an unknown enemy is attacking our... Look out!" Another explosion was set off, interrupting the soldier's sentence. The soldiers were firing at someone, or something, that was off the screen. The soldier started to speak again. "Send backup! Send anyone! We can't hold it off much... Guah!" The transmission ended and the screen started fuzzing. Shadow looked at the soldier. "Rewind the video to 2 seconds before the transmission ended."

"Yes sir!" The soldier started to rewind it. As he did, Shadow noticed that on the screen was a figure. Not one of the G.U.N soldiers, but a flying figure. A blue flying figure. "Zoom in on the figure on the right side of the screen and clear the picture up." As the soldier did as he was told, Shadow realized what it was that attacked the soldiers. Only one other thing looked like him besides Sonic, and would be this evil. Shadow slowly said the name out loud. "Metal Sonic!"

Tower turned back to Shadow and started to speak. "We figure that Doctor Eggman found out about the emerald before we did. So he sent Metal Sonic to retrieve it for him." The commander shook his head. "We lost many good men down there today. And I don't want to loose anymore. And that brings us to your assignment."

Shadow turned to Tower. "What are your orders sir?"

"You're mission is to retrieve that chaos emerald and destroy Metal Sonic before we loose anymore soldiers."

"But I thought you said that the soldiers that were already there were all dead."

"We had already sent more troops to Mount Everest Before we had received the video. By the time that we figured out it was Metal Sonic, there was no way to stop them."

"Why didn't you call them back via the radio?"

"Because the radio frequency that we use to keep constant contact with them is being jammed. We figure that Eggman had found out about the extra troops and jammed the signal so that they could not return to base. Which means if you go in there, there is noway for you to contact us. The only way home is to get that chaos emerald or to stop the jam. Any questions?"

"When do I leave?"

"Five minutes from when we are done talking here. That is all." Tower gave off a salute. "Good luck, agent Shadow."

Shadow returned the salute and held it for two seconds, then turned around and started to head towards the hanger.

          _________________________________________________________________________________________________________________________

"ETA 2 minutes sir!"

Shadow looked at the pilot that was speaking to him for a second. Then he turned his attention back to the mountains. He had been in the helicopter for awhile now, thinking about what had happened to him in the passed. He had been through a lot, seeing his only friend die as he stood trapped on the other side of glass, loosing his memory for a long time, thinking for part of his life that he was not the real Shadow, he had been through many things that he wished that he could have done something about.

"But that was the passed, and this is the future. I may not be able to fix all the things that I had done in the past, but I can make things better for the future."

"ETA 30 seconds!"

Shadow opened the side door and looked down. There was snow everywhere, but no signs of battle. He looked at the pilot. "Where am I landing exactly?"

"The original LZ is too hot. Our soldiers are fighting as we speak. We are dropping you off 250 yards south of the battle ground." The helicopter slowed down to a halt. "We're here sir! Let me lower this bird a little bit so that you can get off safely."

Shadow looked at the pilot one last time. "No need." Shadow turned back to look at the ground and jumped. As he fell, he could picture the surprised look on the pilots face. That made him smile.

As Shadow landed, snow flew everywhere, making it look like a bomb had just been set off. When he got back up, he looked up at the copter and gave a thumbs up, letting the pilot know that it was alright for him to leave now. Shadow watched the helicopter leave for just a minute and then turned around and started to run north, towards the battle field.

He looked at his wrist watch. Every G.U.N agent was assigned one so that the could keep track of time, as well as mission updates and a GPS system that allowed soldiers to pinpoint where they were supposed to go and how far the destination is. 100 yards left. Shadow did not dare run as fast as he could to the battle. He wanted to be sure that his first attack landed on Metal Sonic, and not one of his own men. 50 yards left. Shadow slowed down to the point that he was running at the pace of a human track runner. 25 yards left. Shadow veered off course by about 5 yards so that he could find cover to look at what was going on before he went in. 10 Yards left. He could hear the sounds of fighting as he approached. He slowed down to a jog. 5 yards left. He could see the explosions now. He hid behind a tree and looked at what was going on.

Soldiers were shooting into the air and throwing grenades at what looked like nothing. "There is no way that they will be able to hit Metal Sonic. He was designed to match the speed of Sonic. I need to act fast. And for that, I will need to find him." At that moment, a blue flash caught Shadows attention. He kept his eye on that blue blur that was flying around the soldiers. "I am one of the few beings on this earth that can actually keep up with his movements. I better get ready." Shadow started to build up his chaos energy. In 2 seconds, he had built it up and formed it into the shape of a spear. He look back at the field and noticed that everyone had stopped fighting. All the G.U.N soldiers were just starring at Metal Sonic, who was in turn, starring back at them. Then he raised his hand into the sky. Sparks of electricity started to shoot from his hand as a little ball of energy developed and started to grow. He was about to wipe out everyone. "Now's my chance!"

Shadow jumped out from behind the tree and started to run towards Metal Sonic. He threw the spear, which hit Metal Sonic in the back of the head. Shadow jumped up into the air. Just as Metal Sonic was turning his head, Shadow delivered a kick to his head and kept his foot in Metal's face as they fell to the ground. Once they landed, Shadow jumped up into the air and started his spin dash attack. He landed square on Metal Sonic's chest and stayed there for a little while. "Everyone, clear the area!" All the soldiers looked at both hedgehogs for a few seconds before acknowledging that they were being talked to. They all started to evacuate the area. "Good. Now I don't have to worry about holding back my power."

Shadow discontinued his attack and, while in a hand stand, grabbed hold of Metal's arms. He landed on his feet and threw Metal over his head and towards the side of the nearest mountain. He wasted no time just watching his handy work. He ran as fast as he could past Metal Sonic's still flying body and stopped 15 yards in front of him. Once Metal Sonic was close enough, Shadow lifted his leg up and kicked the still flying body up towards the sky. Shadow looked at where the body was going to start falling at and looked for a place to intercept it while it was still traveling at a great speed. "Chaos Control." Shadow teleported himself in front of where Metal Sonic's body was flying towards and used his rocket shoes to keep himself afloat. As the body flew closer, Shadow grasped both of his hands and held them into the sky. When he thought that the body was close enough, he threw both his hands downward, which landed right on Metal Sonic's head.

As he watched Metal fall towards the ground, Shadow raised his right hand and started to form another chaos spear. "I have been waiting to try out this attack." Shadow looked back down and saw where Metal Sonic's body had landed. "Chaos..." He herald the green spear down down towards the mini crater that Metal Sonic made. He waited until the spear was 30 yards away above the body. "... Scatter!" Shadow clenched his right hand into a fist. The spear, now 20 yards away from the motionless body, separated into what looked like 20 or 30 different spears. The spears hit the ground where Metal Sonic was, creating several green explosions.

Shadow looked at the crater that was left from the explosions. All that was left was a few scattered pieces of the remains of Metal Sonic. "Now all I have to do is find that chaos emerald. It should be around here somewh...Ah!" Shadow grunted as he was hit in the back of the head. Before he could react, he was hit in the stomach by a black object. Shadow fell to the ground, creating another crater. As he got up from his fall, he looked up to see what hit him. What he saw surprised him. It was not one, but two flying objects. They slowly started to fly towards him. What he saw was something he had not seen before. He saw another Metal Sonic and another robot. It looked like a Shadow android, but it was darker looking. The robot threw an object towards Shadow. He braced for impact. The object landed at his feet. He looked at it and picked it up. There was a screen on it that turned on as soon as he grabbed it. Eggman's face appeared.

"Hello Shadow. Were you the one who destroyed one of my Metal Sonic 9.0 units? No matter, for I will retrieve that chaos emerald with my two new robot minions. On that note, let my introduce you to them. The blue one is Metal Sonic 10.0. And that black one..." Shadow looked at the black robot that Eggman was talking about. "...is Metal Shadow 1.0. My latest creation that is superior to you in every way possible. You can't win!" The ball that Shadow was holding started to float. Shadow looked back at the robots. "Chaos Control." He teleported behind Metal Shadow and kicked towards his head. To his surprise, his robot doppelganger grabbed his foot and threw him towards the ground.

Shadow broke his fall using his rocket shoes. Before he could launch a counter attack, Metal Sonic appeared behind him and kicked him towards the ground. Right before he hit the ground, Metal Shadow landed a kick, sending Shadow upward. Before he started to slow down, Metal Sonic kicked him so that he flew sideways. Metal Shadow intercepted Shadow and kicked him upwards, while Metal Sonic kicked him to the side. Before Shadow could react, Metal Shadow landed on him while he was still flying and plummeted to the earth. they landed on the ground, creating another crater. Metal Shadow flew away and joined Metal Sonic.

"It's no good. I need more power if I want to beat both of them." Shadow reached for his wrists and removed his inhibitor rings. Immediately, he felt a huge surge of power flow through his body. He looked at the two robots for a few seconds and then flew towards him at an amazing speed.

Both the Metals went into a defending stance. Just as he was closing in, Shadow vanished. He reappeared behind both the metallic hedgehogs and punched them in the back of the head, sending them flying.

"I already feel my power fading away. I have to end this quickly, otherwise they will be the end of me!"

Just then, Metal Shadow appeared behind him and punched him in the face. Shadow turned around and kneed his metal twin in the stomach. shadow curled his hand into a fist, ready to hit Metal Shadow with a barrage of punches. Before he could even touch The robot, Metal Sonic flew in and and kicked Shadow in the back of his head. Both hedgehogs went flying away from Metal Shadow.

While they were still flying, Shadow reached back and grabbed a hold of Metal Sonic's leg. He threw the blue hedgehog over his shoulders and began to start swinging him around. Shadow noticed Metal Shadow flying towards him, so he swung Metal Sonic around one more time and then let go, sending one metal hedgehog to the other.

Just before Metal Sonic could collide with him, Metal Shadow disappeared. He reappeared behind Shadow and prepared to kick him. Shadow teleported behind Metal Shadow and shot a Chaos Spear point blank at the back of his metal doubles head. Metal Shadow teleported behind Shadow and tried to kick him in the back of the head, this time succeeding. The Chaos Spear that was fired flew downwards, straight into Metal Sonic, who was flying towards the two fighting hedgehogs. The green bolt hit Metal right between his red eyes, sending him flying into the ground.

Shadow turned around and punched Metal Shadow as hard as he could in the face, sending the robot backwards at an incredible speed. Metal Shadow used his rocket shoes to stop his descent backwards and faced Shadow. He put his hands by his sides as if getting ready for a quick draw contest. His hands stared to glow green. Shadow looked at his metal twin and smirked.

"Fine. I'll play your little game." Shadow got into the same pose as Metal Shadow and his hands started to glow green as well. Both black hedgehogs starred at each other for a few seconds. Then, simultaneously, they shot both their hands forward and fired endless barrages of Chaos Spears towards one another. Metal Shadow started to push Shadow's attacks back.

"I... Will... Not... Lose!" Shadow put all of his energy into his attack. Shadow's Chaos Spears got bigger and came at a faster rate then before. Metal Shadow's Spears started to get pushed back. Soon, Shadow's attacks had reached him and he was engulfed by a bright green light.

When the light dimmed down and the smoke had cleared, Metal Shadow was still flying. Sparks fell out of different parts of his body and he twitched his head up and down. Shadow teleported above the robot and kicked him on top of the head, sending his metal duplicate towards the ground. Metal Shadow hit the earth, right where Metal Sonic was.

Shadow landed on a blanket of snow and kneeled. He grimaced and started panting. "I used too much energy on that last attack. I need to find that Chaos Emerald and get back to base."

Just then, Shadow heard a noise. He looked up and saw both Metal Sonic and Metal Shadow flying towards him slowly. They both landed on the ground simultaneously. The orb that Eggman had been talking through came up to Shadow out of nowhere and the little screen on it turned on. Eggman's face appeared.

"Well done Shadow! You held your ground against both of my strongest robot minions. Sonic would not have lasted 5 minutes against both of them. But you manage to damage both of them! I am impressed."

Shadow looked up at the orb. "Is there a point to this? Or are you just trying to distract me for something?"

Eggman smiled as he started to speak again. "There is a point to all of this. You did good Shadow. However, these to robots have one more trick up their robotic sleeves."

As soon as Eggman finished talking, both Metal Sonic and Metal Shadow fell to pieces. All the parts fell to the ground. Before Shadow could figure out what was going on, the parts started floating. They all formed into a ball and a light shot out of it, blinding Shadow. When the light had dimmed, Shadow saw a figure standing in front of him. Different parts of it were black and other parts of it were blue. Eggman began to speak once more.

"Behold, the Metal Shadic!!! Hahahahahahahah!!!"

"Metal... Shadic?!"

"Yes! Just like how you and Sonic fused to beat that hedgehog known as Nazo, my Metal Sonic and Metal Shadow fused into Metal Shadic! While it might not be as powerful as the original Shadic, it is much more powerful than you, even in your Chaos form! You can't win!"

At that moment, Metal Shadic appeared in front of Shadow and kicked him in the chin, making Shadow jump five feet of the ground. Before he could land, the fused monster punched him, causing to go flying backwards. While Shadow was still in the air, Metal Shadic teleported in front of him and kicked him into the air. Shadow flew upward a great distance before he used his rocket shoes to break his ascent.

Metal Shadic appeared in front of Shadow and started to repeatedly punch him in the face with lightning speed. "He's too fast! I can't block or even dodge his attacks!" Shadic 1.0 finished his attack by punching Shadow towards the ground.

Shadow unburied  his head out of the snow and looked up to where Metal Shadic was flying. He blinked and when he opened his eyes, the robot was gone. He heard a thumping sound, as if a giant hand taken a step on the snow-paved ground. Shadow turned around and saw black and blue menace. They starred at each other for a minute before Metal Shadic started to slowly walk towards him. The robot's right hand closed into a fist and it started to glow.

Shadow opened his right hand and started to build up power. "I don't have much power left. I have to catch him by surprise, otherwise I won't be able to beat him." He winced as he felt all of his power flow into his hand. He looked back at the advancing metal fiend. He took a step forward and herald the green ball of chaos power. The ball flew at an incredible speed towards the robot.

While he arm was still glowing, Metal Shadic crossed his arm and waited until the ball was close enough to singe human skin. Right before the attack hit him, the robot quickly opened up his hand and backhanded it, just as if he swatted away a tiny fly. Shadow's eyes widened as he realized his last ditch effort to stop the robot from finding the Chaos Emerald had failed. Metal Shadic stood still for a few seconds, then vanished. Shadow (out of reflex) turned around. Just as he did, he froze as he felt a sharp pain in his stomach. Metal Shadic had teleported behind him and gave him an upper-cut to the gut.

The robot pulled it's hand back while activating it's rocket-shoes. It lifted the right leg up while Shadow stood there, frozen in pain. Metal Shadic swung it's leg forward and hit Shadow in the stomach, sending him straight into the air. After watching the body of the black hedgehog fly up for 50 yards, Metal Shadic warped above and curled up into a ball while starting to spin. The metallic demon than shot downwards and landed right on Shadow's head. Shadow plummeted into the ground, creating (yet again) another crater.

Eggman's orb flew along side Metal Shadic. "It's time to finish it. Metal Shadic, use all of your power and finish him off!"

As it rose them up high, Metal Shadic's hands started to glow as surges of electricity flowed from it's power turbine to them. The robot pointed both open hands towards the ground where Shadow had landed. When it felt all the energy it could spare go into the hands, it started to fire rapid shots at Shadow.

Shadow looked up as he saw the hundreds of small balls of energy fly towards him. "I can't move. I am helpless." The energy attack flew closer to Shadow. "No! I will not die here!" He held his hands up just as the energy balls started hitting the ground all around him.

Metal Shadic thrusted both it's hands forward and back at a lightning speed, shooting more balls of energy each time that a hand was sent forward. A giant yellow ball was building on the ground where Shadow was. The coby-bot stopped it's rapid fire attack and held it's right hand high in the air, building a beach ball sized orb of power. It hurled it towards the bigger ball on the ground. Once they made contact, the big ball expanded, a sight that would blind anyone close by that was directly looking at it.

Dust and snow floated through the air as the robot lowered itself down towards the ground. Eggman threw his head back laughing. "Hohohohoho! And so ends the tale of Shadow the Hedgehog!" Eggman looked back at where Shadow had been. He then pressed his nose against the screen. "What?! That's impossible!!!"

As the dust started to clear, a bubble-shaped orb was on the ground. It disappeared and laying there on the ground was Shadow. Right before the barrage of energy balls hit him, he formed a shield with his Chaos energy.
