Note To Readers: I just finished TMNT UNLIMITED. I'm trying to revamp my style of writing and get deeper into my stories. I am trying to have better descriptions and better storylines. So enjoy!!!

Chapter 1: Metallic Homecoming

"Systems On. Full Power restored. Damage Report: Tesla Power Coil, Left leg. Scanner Report. Location: Atmosphere of Earth. United Federation Government Base number 272002. Code Name: Space Colony ARK. Life form Report: 1 in area. Activate Search Mode."

Inside one of the many chambers of the ARK, a machine is awakened from its deep slumber. The robot stood up on its one leg, and held itself steady with its limp one. The chamber opened, allowing the harmed robot to roam the corridors. It entered a large room that contained a central pod. "Dead End…must find…life form…" The robot turned around and began to exit the room.

He entered a different room that contained a view of all space and Earth. "I have located the Escape Pod Port. Secondary Machine detected." The robot turned around to reveal a large and bulky red robot.

"Intruder. Memory Databank check: Metal Sonic." The red robot reported. "Threat Level: Red. Commence Motive 2: Destroy." The Red Robot's arms transformed, revealing machine guns.

"I…remember…" Metal said. He suddenly remembered his identity. "You attempted to destroy me! You will pay for your disrespecting me, E-123 Omega." Metal activated his main engine and charged at the red robot. Suddenly in midflight, the engine explodes and crashes into the ground. "VOF Engine failing. Power level 67%." Omega began to unload his bullets on Metal, covering the smaller blue robot with dents. "Activate Black Shield." Suddenly a diamond shaped force field covered Metal. "Black Shield dropping power level 32%" Metal stood to his feet. " 12% Power to Main Engine." Suddenly, Metal propelled himself into Omega, ripping through his chest. The two of the robots crashed into the windows.

"Main Power Core destroyed, systems failing," said Omega, as the window began to crack. "Self Destruction sequence starting. 10, 9, 8, 7…" Metal began to struggle to remove his head from Omega's chest. " 5, 4, 3, 2…" Metal kicked off of Omega and sent his body flying through the window, causing space to suck out Omega and the window. A blast shield lowered its self over the opened window, and closed off the space vacuum. The room shook as the robot exploded. " Power level 12%. Must locate Life Form."

"You have," Metal Sonic turned around and saw the life form standing in the door way. " You destroyed Omega. This shows how useless he really was. Still, I hope you are aware that you will not remain a burden to me in my home. Goodbye."

"You can't destroy me," said Metal. " Sonic the Hedgehog…" Metal's system corrected his error. " No…Shadow the hedgehog. His fleshy counterpart. No matter, you will die!"

Metal leaped with his working leg at Shadow. "Foolish machine." Shadow lifted his hand and released a blast of golden light at the attacking robot. Metal was engulfed by the blast and sent flying out a window. The Blast shield closed the window. "Omega was so easily destroyed by a damaged robot. Yet, that robot…he was designed to be just like Sonic." Shadow smirked. "No wonder Omega was demolished so quickly. He still didn't even stand a chance against me."

Metal began to drift into the atmosphere of Earth. "Atmosphere Shield cannot be activated. Power Level 5% and dropping. Main Engine destroyed." Metal started to catch fire and felt his limp leg rip away from him, followed by his right arm and foot. "Power Level 1%. Entering the Atmosphere. Shutting Down." Metal looked down and saw through his red vision the reflection of himself before blacking out.

Days Later

" Systems Start Up. Power Level Rising. Loading Memory Databank" Metal Sonic woke up to the new female voice on his CPU. His vision came in and revealed his new High Definition view. He previously was only able to see things through a heavy red tint. He was able to see clearly and he experienced the random colors of the room.

"Where am I?" Metal sat up and surveyed the room. The room was grey and lit by a single florescent light. Above was a one sided window and in front of Metal, he saw a mirror of himself. "What is this?" Metal looked at himself in the mirror and began to rub his mouthpiece. It was rubber. He moved his hands over his new mouth. He reached into it and ran his fingers across the inside of his mouth and felt the voice box guarded by steel teeth. He continued over to his ears, no replaced with long diamond shaped antennas. He reached back and gripped his quills, which seemed soft and the hung low. He then flexed them and they hardened to that of his original.. He looked at his arms, no complete with bulky forearms and jointed claws. He flexed his hand and a blade extended from the back of his hand. He flexed it once more and it retracted. He turned around and saw a short metal tail.

He looked down at his new oval shaped torso. In the center was a large circular generator that glowed bright blue. He ran his fingers across it. " I replaced your Telsa Power Coil with a Ion Reactor." Metal looked up to see his creator speaking down onto him. " It can generate 12 gigajoules of Power. I also replaced the 4 Valve Organ Fusion Engine with a customized version of my own creation. You should be able to reach a speed faster than the speed of sound. I am actually clueless to how fast you really can go! Your Ion Reactor could can last for centuries."

"Why are you telling me this?" Metal asked.

"Because," the large man turned on the light in his observation deck, allowing Metal to see him clearly. "I WILL complete my plans, and I WILL NOT stands for Sonic the Hedgehog getting in the way. I want you to keep him out of my sight, even if that means killing him."

"And what makes you believe I will help you?"

"You will be destroyed." Eggman laughed. He showed his wrist revealing a remote. " All I have to do is press this button and you will self destruct. You will obey me this time. Now…prove your worthiness!"

Suddenly, a wall opened and revealed a different Metal Sonic. "This is the Metal Sonic I replaced you with when you betrayed me before. He doesn't have an adaptable brain like you have, which is both an improvement and a flaw. He is very skilled in combat, yet he doesn't have a weapon's system like you do now. I will leave you to your match."

"Objective Located: Destroy!" The Metal Sonic charged at its original, slashing at him with his claws. The original extended his hand blade and slashed at the remake. The remake fell back, but got back up and attacked again.

Metal activated his flight mode and revealed his new turbines. He had one on his back and one on each foot. His tail extended to become stability fin. " Interesting." Metal opened the ball of his hand and shot out a blast of electricity that shot the replica into a wall. " Very interesting."

Metal then landed on the ground. His forearm's opened up and two disks formed on each side. His spines started to extend and rap around and connect to the disks. Once completed, it formed a sphere. Suddenly electricity charged around the ball and blasted off to its target.

The replica stood up, already damaged from the electric blast. He looked through his red vision and looked at the electric ball that was charging. Suddenly, it is ripped apart as the metal sphere crashed through the robot. Metal transformed back, victorious. " Sonic…your time is almost up."
