Mecha Overlord chapter three: The battles

Location: Wave Ocean

Silver, Blaze and Mephiles searched everywhere, but couldn't find the Emerald. "You sure it's here Mephiles?" Silver asked. "Yes, but it is hidden quite well. We will find it though…" Mephiles replied. They walked around a little and found some robots, they weren't Eggman robots though. These robots were made by G.U.N.! "I'll handle them." Blaze said. Blaze used her Pyrokinesis to make flames enter the ground. Blaze moved her eyes and was looking at the robots. She raised her hand and bang! Eruption! She made the flames rise from the ground and they burned the robots. Only a pile of ash was left. "Wow, that must be your secret move…" Mephiles said. "Yes, it is." Blaze said. "Hey look! A Chaos Emerald!" Silver said. He saw it sparkling in the ashes. Silver used his Telekinesis to get the Emerald. "Great! We got one!" Mephiles exclaimed. Suddenly, Silver was punched in the back and flew 15 feet away, crashing into a rock. The one who punched Silver was Metal Knuckles, who quickly grabbed the Emerald. "I believe that belongs to us!" Metal Knuckles said. "Mecha Shadow's minions!" Blaze thought. "We aren't going to let you keep the Emerald without a fight!" Mephiles said. Silver got up and the two teams charged into each other. Metal Sonic punched Silver in the stomach and kicked him in the face, Silver wasn't going to give up that easily though and used his Telekinesis to pick up some rocks to throw at Metal Sonic. Metal Sonic dodged them all and used Chaos Control to appear behind Silver and use his Metal Sonic Combo, 30 rapid kicks and punches with enormous amounts of power. Silver was kicked into the sand with the last kick and was getting weaker. He got up and used his Meteor Smash while gathering over 300 rocks. Metal Sonic was hit but didn't want to give up so easily and used his Chaos Blast to hit Silver. Silver survived and they clashed into each other once again. Tails Doll was fighting Mephiles, Tails Doll used his axe to hit Mephiles hard and used Demon Beam to finish him off. Mephiles, however, was still alive and used his cloning ability to create two clones. The clones and Mephiles kicked and punched the Doll to defeat him, but Tails Doll used his red gem before the finishing blow to destroy the clones. Tails Doll used his secret move: Demon explosion to unleash 100 demons from hell. They attacked Mephiles and knocked him out. Blaze was having a hard time battling Metal Knuckles. Metal Knuckles was way too powerful to beat and had the upper hand. Blaze used her Pyrokinesis to create a Fire Sword. She could keep up with Metal Knuckles now. She hit him over and over and over until he was knocked into a rock. Metal Knuckles became angry and wanted to finish Blaze off. He used his Metal Knuckles combo to finish her off: 15 Knuckle punches and 1 full power Knuckle punch. Blaze wasn't knocked out though, and they clashed into each other once again. Meanwhile Silver and Metal Sonic were still fighting. "You will never win! I have to defeat Mecha Shadow!" Silver said. "You are after Mecha Shadow! We too, we thought you were his minions!" Metal Sonic said. "We thought you were his minions!" Silver replied. "Let's stop fighting and work together, okay?" Metal Sonic said. "Great idea! We will definitely stand a chance if we work together!" Silver replied. Blaze, Metal Knuckles, Tails Doll and Mephiles, who had just regained consciousness, heard them. "Good idea…" Mephiles said. "Yeah, we'll be one step closer to defeating Mecha Shadow!" Metal Knuckles said. "But we need a place to stay, a base you know?" Blaze said. "I have an idea!" Metal Sonic said. He picked up the Emerald. "CHAOS CONTROL!" He shouted.

Location: Egg Carrier mark III, control room.

The six heroes arrived in the control room. "We're here! This is the Egg Carrier mark III, Eggman planned on using this when he released Shadow, but abandoned it once he was inside the ARK." Metal Sonic said. "Wow, this is place is big! I don't get why he didn't use this thing." Silver said. "He thought the ARK would help accomplish his plan." Mephiles said. "So this is where we will be staying?" Blaze asked. "Yes, go look around a little if you feel like it. I need to start this thing up." Metal Sonic said. "I'll stay with you, I want to see how this thing works." Tails Doll said. "No wonder why you are a doll of tails! You're just like him!" Metal Sonic said. Metal Sonic and Tails Doll tried to figure out how to start the thing and found a button which says: PRESS TO START. Metal Sonic pressed it and the Egg Carrier began to fly up. In a few minutes they were flying across the sky with the Egg Carrier.

Windy Valley

Robin was jumping from island to island trying to find another Chaos Emerald, but he couldn't find any. "Damn, where are those Emeralds! I'm going to need them…" He said. He jumped from island to island again until he saw a familiar looking robot…. Mecha Shadow. "So Robin, you found me, impressive for a weak hedgehog like you.." Mecha Shadow said. "Weak? I'm not weak. I'm more powerful than you with this Emerald!" Robin replied, showing him the Emerald. "Wrong! I have an Emerald too, that means I am way stronger than you, you insect!" Mecha Shadow said. "I have an idea, we'll fight, who wins… will get both Emeralds!" Robin said. "Prepare for the last fight you will ever get!" Mecha Shadow said confidently. And they began fighting. Mecha Shadow used his Spindash to hit Robin, but Robin guarded. Robin quickly kicked him a few times which stunned Mecha Shadow. Robin then used Light Speed Attack to hit Mecha Shadow with intense power and speed. Robin crashed into the floor, hit Mecha Shadow and the power of the attack left a crater behind. Mecha Shadow got up and teleported, appearing behind Robin and kicking him into the air. He quickly teleported again to kick him into the ground, leaving another crater behind. Mecha Shadow teleported again to pick Robin up and threw him into the air, while preparing a Chaos Beam. He used the Chaos Beam to defeat Robin, who landed on another island. "I can't lose now….. I won't lose now…. I WILL DEFEAT YOU!" Robin thought. Suddenly he rose up in the air and his Chaos Emerald entered his body, giving him a burst of power and a lot of energy. He teleported and appeared behind Mecha Shadow, kicking him into the air. He quickly teleported again and used Chaos Control to stop time. He rapidly hit Mecha Shadow with Kicks and punches, and the effect of Chaos Control was over, Robin used a Dark Chaos Beam to finish him off. He took Mecha Shadow's Emerald and left, he was off to the G.U.N. headquarters.
