Mecha overlord Prologue: The secret project
Location: Green forest, Eggmans base…
Shadow was running through the base, smashing one robot after another. The G.U.N. Commander told him Eggman was developing a secret weapon, and that he would have to find it and destroy it. "The doctor is going to regret making that secret weapon." Shadow said. Suddenly a voice was heard. "Very well Shadow, you've taken out almost every single robot here, but now you'll have to face me!" Eggman said. A giant dragon like creature landed on the floor. Eggman was in the cockpit. "Prepare yourself Shadow, I will end your life once and for all!" Eggman shouted. The dragon robot lifted its claw and tried to hit Shadow, but he avoided the attack. "Chaos control!" Shadow said. "Huh? Where did that hedgehog go?" Eggman wondered. Shadow then landed on the cockpit. "Chaos..." Shadow said as he began glowing red. "BLAST" Shadow shouted. The robot dragon was destroyed by the explosion and Eggman barely survived. Shadow walked up to him. "Please let me live! I'll pay you! I'll go to jail! Just let me live!" Eggman begged. Shadow, however didn't want to show mercy. He grabbed Eggman. Shadow threw him against a wall. "Goodbye forever, doctor!" Shadow exclaimed. "Chaos Strike." Shadow said. Eggman didn't know what was happening, but suddenly shadow appeared in front of him, his hand surrounded by electricity. And then bam, Shadow punched Eggman in the stomach and Eggman was electrocuted. Shadow looked at Eggmans body, smiling. "Finally this world can live in peace." He said. He was walking through the base until he heard a voice. "EGGMAN KILLED, EGGMAN KILLED! RELEASE PROJECT MSH! RELEASE PROJECT MSH!" The voice said. Shadow was now on his guard. "This must be the secret project! Time to destroy it!" Shadow said confidently. Suddenly a robot came flying towards him. The robot kicked Shadow in the stomach before Shadow could even dodge. When Shadow stood up he saw how the robot looked like. It was similar to Mecha Sonic, but this one looked like Shadow. "Well, Well, Well, Shadow the hedgehog. I finally get to see you." The robot said. "Who are you? And how do you know my name?" Shadow asked. "Just call me Mecha Shadow! The REAL ultimate life form!" The robot, now known as Mecha Shadow said. "Now if you excuse me, I have things to do…" Mecha Shadow said. "CHAOS CONTROL!" He shouted, as he disappeared. "I got to go to G.U.N. headquarters and report this to the Commander!" Shadow said, before using Chaos Control.
