Mecha Overlord chapter one: Team Metal

Location: Radical City lab, Tails Dolls chamber.

Metal Sonic was walking through the chamber, searching for the Tails Doll. "Damn! Where is he?" Metal Sonic said furious. He walked around a little until he spotted him. He walked up to him, and saw he was sleeping, Tails Doll was the only one who was in the lab, he could not leave the lab though, it had to be opened from the outside. Metal Sonic slapped the Tails Doll, but it didn't work. "I'm going to devour your soul…" Tails Doll whispered. He was still sleeping and was obviously dreaming. Metal Sonic was tired of waiting and punched him in the face. He woke up. "WHO THE HELL DARES TO PUNCH THE GREAT GAMING SATAN!" He said furiously. He noticed Metal Sonic. "Metal! Why are you here and why the hell did you punch me?" Tails Doll asked. "Because I need your help and you were sleeping." He answered. "And why do you need my help?" Tails Doll asked. "Eggman is dead, but he made a robot named Mecha Shadow, he is dangerous and can destroy the world if he gets the Chaos Emeralds!" Metal Sonic answered. "But you do know that we are trapped here right?" Tails Doll said. "Just a second." Metal said. "Metal Drill" He said. Metal Sonic drilled through the wall and for the first time in 15 years, Tails Doll saw light. "Wow, just wow! Where did you learn that?" Tails Doll asked. "I'll explain later, right now we got to go to Reactive Factory!" Metal Sonic said. "Metal Knuckles?" Tails Doll asked. "Metal Knuckles." Metal Sonic replied. And thus they left off…

On the way Metal Sonic explained how he learned that stuff and explained his plan in Sonic Heroes to copy all the data, transform into Metal Overlord, and getting defeated…

Reactive Factory lab 2X, Metal Knuckles chamber.

Metal Sonic and Tails Doll entered the chamber. It looked so mechanical. They spotted Metal Knuckles and ran towards him. "He's turned off…" Tails Doll said. "I'll activate him." Metal Sonic said. He searched for a switch and found one. He Activated Metal Knuckles. "Huh? Where am I?" Metal Knuckles asked. "Reactive Factory, we just activated you." Tails Doll said. "Oh cool, but why?" he asked. "Metal Sonic will explain." Tails Doll said. "Eggman is dead, but he created a robot named Mecha Shadow! He is very dangerous and can destroy the world if he gets the Chaos Emeralds!" Metal Sonic said. "Okay, I'll help you guys!" Metal Knuckles shouted. "Sweet, but we need a team name…." Metal Sonic said. "…Why?" Tails Doll Asked. "Because when I tried to destroy Sonic and friends they had team names like Team Sonic, Team Dark, Team Rose…" Metal Sonic said. "How about Team Metal?" Metal Knuckles suggested. "That would work!" Tails Doll said. "But where will we go first? We need to find the Chaos Emeralds before Mecha Shadow!" Metal Knuckles exclaimed. "We'll go to Wave Ocean, my sensors indicate that there is a Chaos Emerald there." Metal Sonic said. And thus they went to Wave Ocean.

G.U.N. headquarters.

Shadow entered the headquarters and walked to the Commander's room. "Shadow, how did the mission go?" The Commander asked. "I killed Eggman but the robot was freed when I killed Eggman… Mecha Shadow is his name… He is much more powerful than anything I've faced before, he defeated me in a matter of seconds…" Shadow answered. "Oh… you did your best to defeat that robot, I know that. If he really is that powerful he'll probably go after the Chaos Emeralds…." The Commander said. "Great, do you know where one of the Emeralds is?" Shadow asked. "Yes, one is located in the Lost World. You'll need to go the Mystic Ruins for that. But I want Sonic, Tails and Knuckles to go with you." The Commander replied. "Fine with me, I'm going to need them." Shadow said. At that exact moment Sonic and co. walked in. "Alright, time to go the Mystic Ruins then!" Sonic said. "Let's do this!" Tails said. "Time to go retrieve the Emerald!" Knuckles shouted.

Unknown location.

"Ugh where am I?" A male red hedgehog said. "I must've passed out after that battle with Mecha Shadow." He said. "Okay Robin, time to go search for the Emeralds!" Robin said. Robin is a red hedgehog similar to Shadow but without markings on his quills, He has black eyes and tends to stay calm, and he has purple shoes, shoes similar to Sonic's.

What did you guys think of this chapter? Review! And I'll probably post the next chapter in a few hours. After that I'll slow down a little.
