"You failed!" Robotnik was sitting in a floating chair in front of a trio of floating keyboards of light.

"Yes!" Metal Sonic stood behind Robotnik. He toyed with the idea of blasting the fat doctor in the back with his lasers, but he didn't feel like blowing up.

Robotnik nodded, "I don't blame you this time. Even I didn't think GUN would get involved so early in the game." Robotnik started typing and three screens appeared, "The girl was injured, but she will live. Luckily for you."

"Why is she so important?"

Robotnik chuckled, "All will be revealed in time." The fat man pressed several buttons and a large screen appeared. It showed a large mountain with a pair of steel doors in the side of it. "You and Sperk will lead my strike forces so that we may acquire the next piece of my plan."

"As you command!" Metal bowed and stepped out. Metal walked through Robotnik's hidden base and wished he had just kill the man. He hated him for creating him, for blowing his chances at ruling the world, and his inability to defeat a teenager. Metal walked into the small medical ward. Since most of Robotnik's followers had no need for doctors, he had little need for it. But he was himself, human, "Humans are so weak!" Metal spotted Sperk sitting next the girl echidna who was sleeping on a medical bed. Her torso was bandage and she had an IV tube in her arm. Sperk's eyes had turned cobalt blue. "Sperk!" The hedgehog's eyes turned crimson as he turned and looked at the android, "Our lord is sending us on a mission." Sperk nodded and stood up. Both walked out of the ward and towards the hangers.

Sonic and Shadow walked in-between four human troops as they walked down a metal hallway. They had landed a few minutes ago, but had no idea where they were. The walked up to a gray metal door and it slid open. Both hedgehogs walked into a large command center. It was circular with computer screens and terminals all around the wall. Humans sat at each terminal. A large chair was in the center of the room. It spun around and a man in a blue suit stood up out of it, "Sonic! Shadow!" He walked to them and held out his hand, "Thanks for coming."

Sonic shook the man's hand, "Thanks for the rescue Mr. President!"

The man held out his hand to Shadow, but the hedgehog just shrugged. The man nodded, "Sorry! We have a problem."

"Robotnik!"

The president nodded, "Our satellite images and radar has picked up ships matching Robotnik's energy signature have appeared all over the planet. But we can't seem to keep track of them or figure out what he is up too."

Shadow walked past the president and sighed, "I have an idea!"

"Well don't keep us in suspense!" Sonic quickly ran up next to him.

"He is creating something!"

"How do you figure that?"

"That hedgehog, Sperk called me a prototype. That echidna that attacked you in West City. How Metal Sonic can use Chaos Control. Robotnik is attempting to create something. But what?" The room shook and red lights and alarms went off.

"Report!" The president jumped into his chair.

"A large burst of energy impacted the outer doors." One of the solders at a station brought up a visual on a large overhead screen. A large robot turtle was slowly walking towards them. On the turtle's shell was a large beam weapon.

The screen sparked and Robotnik's image appeared, "People of Earth! I the brilliant Dr. Robotnik have created the ultimate army. To prove my power, I will kill the president of The United Federation. HAHAHAHAHHA!" The screen returned to normal, but the turtle had been joined by six others and a hundred hedgebot troops. Four Egg Warships floated down from the sky and hovered over the army.

The room erupted to life as orders were sent to the defense force. Sonic and Shadow headed to the door. "Hold on!" Both hedgehogs stopped as the president stood up, "GUN can handle this. Send GUN Sentry! I won't let that man have his way."

The doors on the side of the mountain slid open and GUN troops poured out of the opening. Several black tanks and armored mechsuits rolled out. They took position as Robotnik's forces stopped a mile from the mountain. A large silver humanoid robot stepped out of the base. It had large chain guns on its arms and shoulder rocket launchers. Jets activated in its feet and it flew into the sky. From Robotnik's side, a large metal ball rolled forward. It uncurled and reviled itself to be Metal Sonic. The flying robot stopped and hovered above the android. They were halfway in-between each army. The robot aimed its chain guns at Metal, "I am GUN Sentry! You our outnumbered and outmatched. You have five minutes to surrender."

Metal chuckled, "So there is a human in that shell." His blades sprang out of his arms and he grasped them, "Like I would surrender to a human!" Boosters activated in his feet and he jumped into the air. GUN Sentry fired his chain guns, but Metal moved too quickly and shot above him. Metal threw his daggers and they impaled the rocket launchers on his shoulders. They sparked, but their ammo didn't explode. Metal grasped the chains attached to the blades, "I can't fly, but my technology is far superior to yours." GUN Sentry fired at Metal as he dropped to the ground. Metal ignored the impacts to his arm and tugged on the chains. GUN Sentry set his jets to full burn, but Metal kept him still. The bullets from the guns ripped into Metal's armor, but it held. Metal would have activated his guns, but he couldn't give the flying human a chance to hit a vital system. A green ball shot across the area and shot into the air. It rammed into GUN Sentry's back. The temporary loss in balance was enough to allow Metal to drag the man out of the sky. GUN Sentry crashed into the ground. The ball uncurled into a green hedgehog. The hedgehog pulled four daggers from his belt and threw them. The impacted the ground around GUN Sentry and exploded. Metal nodded and activated his tri barrel cannons in his shoulders, "Took you long enough, Sperk!" Metal retracted his blades as the robot pushed himself up. His once shinny silver armor was dented and burnt. The GUN forces behind him started to move. GUN Sentry flew into the air in an attempt to retreat. Metal sent a radio signal to the turtle tanks. They locked on and fired their plasma burst. The shots hit GUN Sentry and the bot exploded.

"You could have killed him yourself."

Metal glanced at Sperk, "He wasn't worth my time. Attack!" Robotnik's forces moved to attack GUN's.

"No!" The president shot out of his chair, "He beat our best weapon."

"Second best!" Shadow turned towards the door, "I'll handle them."

"Wait up!" Sonic was quick to follow him.

The president just sat back down and held his head in his hands, "We're counting on you two now."

Sonic and Shadow made it halfway down the hall before a hidden doorway in the wall slid open. The GUN Commander stepped out, "Sonic! Shadow! I have something for the both of you." Both hedgehogs followed the large man in uniform into the hidden room. On a steel table were a pair of foot long metal rods and a pair of guns. The commander picked up the two rods, "These are for you Sonic." He handed them to the blue hedgehog. Sonic pressed a hidden button on each and a blue blade of energy appeared out of each of them. They started at each end of the rods, arched over his fists, and joined to form a pair of three-foot blades.

Sonic swung them around, "I don't really like weapons!"

The commander sighed, "These were designed just for you."

Shadow nodded, "Robotnik is upping the stakes. We will both need to rise to the occasion." Sonic nodded and deactivated the blades.

"These are for you Shadow!" The man handed Shadow the guns. They were made of red and black metal. "These are advance blaster pistols. Capable of automatic fire and single burst fire." Shadow nodded his approval as the commander grabbed a pair of black belts from the wall, "Use these to hold your new weapons and good luck. My troops will offer you whatever help they can." Both hedgehogs left.

Metal and Sperk ran towards GUN's bases as the two armies fought around them. The metal hedgehog had been repaired.GUN had more troops, but Robotnik's forces were unyielding. Had no concern about their lives or pain. So far they were even. The few troops the two hedgehogs ran into were easily dispatched. They stopped in front of the closed metal doors. Sperk gave a signal to one of the Egg Warships. Hanger doors on the underside of it opened and hundreds of objects flew out of it. They were robotic yellow and red bees. The size of a GUN Beetle, they used jets instead of wings and their stingers held a laser cannon. Robotnik had upgraded these old Buzzbombers and they effectively distracted GUN's robots. With the beetles distracted, five more objects dropped from the ship. They were eight-foot tall black and red echidnas. Dressed in cyber armor, they had a large plasma cannon on their backs. Metal and Sperk stood back as the echidna's pulled the cannons from their backs and took aim at the door. Each one fired a steady stream of green energy at the door. The beams intersected and hit one spot at the bottom of where the two doors connected. Several GUN troops tried to stop them, but Metal and Sperk were quick to intercept them. The echidna's stopped firing and switched their weapons to normal mode. They turned and fired bolts of energy at the GUN troops. A small hole had been burnt through the steel doors. Metal sent a radio signal and several hedgebots curled into balls and rolled into the hole. Metal and Sperk followed them in.
