Mecha Overlord chapter five: Hot, cold and in between

Location: Dusty Desert

Sonic, Tails, Knuckles and Robin walked through the desert, hoping to find Mecha Shadow's forces. "Man, have they left? It's like they aren't here at all!" Knuckles said. "Relax, this desert is big, they are here." Robin replied. "Yeah, this desert is big, I remember when I had a whole pack of robots following me!" Tails said. "Ugh don't remind of that… I had to run through here to save Elise, ugh memories of her kissing me are still haunting me…" Sonic said. "Oh yeah, I remember that!" Knuckles said. "You guys want to hear a lame joke?" Tails asked. "Sure." Sonic, Knuckles and Robin replied. "Will you guys remember me is 5 seconds?" Tails asked. "Yeah!" Knuckles, Robin and Sonic replied. "In a minute?" "Yeah!" "In an hour?" "Yes!" "In a day or week?" "Of course!" "In a month?" "Yes." "In a year?" "Yup!" "Forever?" "Heck yeah!" "Knock knock!" "Who's there?" "YOU GUYS DON'T REMEMBER ME!" They all laughed. "That wasn't so lame!" Knuckles said. They spotted some robots. "Damn! They are here!" Sonic said. "Relax!" Robin said. "We can take them." Knuckles said. "Hey isn't that…. IT'S MECHA SHADOW!" Tails shouted. The robots heard him and marched towards their location. "Well, well, well, look who we have here? A bunch of enemies!" Mecha Shadow said. "We can take you on! You are nothing!" Robin said. "Oh really? I can destroy you all if I feel like it." Mecha Shadow replied. "Face it, you can't destroy us without any Emeralds, we're too strong for you with them!" Knuckles said. "Let's battle to find out!" Mecha Shadow replied. Sonic ran towards him and used a spinning kick, but Mecha Shadow grabbed his legs and threw him up in the air. Mecha Shadow spindashed towards Knuckles, who guarded. Mecha Shadow launched missiles at Knuckles who couldn't avoid them. Robin made a sword out of electricity and attacked Mecha Shadow with it. Mecha Shadow guarded, but the attack was too strong and hit him, he was stunned. Tails used an Arm Cannon to hit Mecha Shadow with a Plasma Ball. Sonic finally landed on the ground, Mecha Shadow wasn't stunned anymore and grabbed him up. He was ready to launch a missile in his face. Knuckles hit Mecha Shadow before he could launch the missile, and flew towards Knuckles. He punched him with immense power and knuckles crashed into a rock. Mecha Shadow flew towards Robin next, ready to kill him. He used his Mecha Shadow combo, a lot of kicks and punches, a few missiles and a spindash. Robin's injuries were heavy, he couldn't stand up. Mecha Shadow grabbed the three Emeralds he had, and punched Robin until he coughed up blood. Sonic stopped Mecha Shadow with a Spindash. "I'll admit that you are all putting up a good fight, but it isn't over yet…!" Mecha Shadow said. The Emeralds circled around Mecha Shadow and entered his mechanical body. He transformed into Super Mecha Shadow. He used Light Speed Attack on Sonic to knock him out. He kicked Knuckles into a rock, hard. And he threw Tails up in the air, teleported, and kicked him down. The transformation ended and Mecha Shadow left with the Emeralds. Sonic, Robin, Knuckles and Tails were completely unconscious.

Location: Ice Cap

The Egg Carrier landed. Metal Sonic, Tails Doll, Metal Knuckles, Blaze and Silver came out. Mephiles wanted to guard the ship, just in case that any intruders wanted to take it. "It is cold, but the Emerald is nearby!" Metal Knuckles said. "Yes, I can feel the energy, but I also sense signs of life nearby." Tails Doll said. "If it's a monster we will take it down…" Blaze said. "Yes, but now let's focus on our mission." Metal Sonic said. They walked through the icy hills, they were beautiful, lots of snow, a sea, and some robots to kill, Eggman robots who were not destroyed and lived here, but harming living things. "There must be a cave nearby, well, an entrance to a cave." Silver said. "Probably not, there can't be any caves here Silver!" Tails Doll replied. "He is right, I sense an entrance to something, but it is blocked." Metal Knuckles said. "I'll burn whatever is blocking the entrance." Blaze said. They walked a little further and saw a few icy rocks blocking a path to a cave. "I'll handle it!" Blaze said. She burned the rocks, and they could enter the cave. "You are a big help Blaze." Metal Sonic said. "Thanks." She replied. They entered the cave. It was full of ice, obviously. Suddenly, a voice was heard. "You won't come any further." A robot said. "Who are you?" Silver asked. "I am E-114 Omicron. An abandoned Eggman robot, I rebelled against him, so he left me here deactivated, but something activated me a few years ago" The figure, now known as Omicron said. "Hey, Eggman was killed a few days ago! And you have a Chaos Emerald. We need it to destroy a robot known as Mecha Shadow." Tails Doll said. "Mecha Shadow…. That name is not in my databanks." Omicron said. "He was created a few months ago." Metal Sonic said. "That makes sense. But if you want this Emerald, you will have to battle me. I want you, blue robot, to battle me!" Omicron said. "Fine but if I win, I get the Emerald and you will join us." Metal Sonic said. "Deal." Omicron said. Omicron launched a few missiles at Metal Sonic, who avoided all of them. Omicron threw a few grenades, they hit Metal Sonic, damaging him. Metal Sonic used a Light Speed Attack to damage Omicron. Omicron began kicking Metal Sonic, Metal Sonic couldn't avoid the kicks. Metal Sonic got up and hit Omicron with a Metal Sonic combo, a few kicks, punches a Light Speed Attack and a spindash. "Sensors indicate I have 30 percent of my health left. Activate Hyper Mode!" Omicron said. Omicron was now faster and more powerful . Omicron used Missile Bombardment, 50 missiles were launched at Metal Sonic, who could only avoid 20. "Prepare for Omicron combo!" Omicron said. Metal Sonic had a plan. He was charging a Full Power Light Speed Attack, 10 Light Speed Attacks which could finish Omicron. They were ready charging the attacks. Metal Sonic used his Full Power Light Speed Attack, Omicron could not avoid it. Soon Omicron was defeated. "Here is your Chaos Emerald, I will also join your group." Omicron said. "Great! Welcome to the team!" Silver said. "Yes, you will be a great help." Blaze said. And the six left the cave and got back to the ship, and they got Omicron a room, and introduced him to Mephiles.

Location: G.U.N. headquarters

"Good to see you again Shadow." Omega said. "Yeah, I haven't seen you in 4 months!" Rouge said. They all hugged and left off to the Lost World, they needed to research the text on the walls.

Location: Dusty Desert

Knuckles regained consciousness. "Ugh, that was a hard battle…." Knuckles said. "The rest better regain consciousness soon!" Knuckles yelled. Tails regained consciousness a few minutes later and so did Sonic. "I'm going to get us outta here!" Tails said. He had a remote with him and pressed the red button. "The Tornado should come here soon." Tails said. "Great, but why hasn't Robin regained consciousness yet?" Sonic asked. "He uses the elemental powers of the Chaos Emeralds, that requires a lot of energy, so he won't regain it soon." Tails explained. They waited a few minutes and the Tornado III arrived. They hopped in and flew away.

Location: The Sky

They flew past clouds, birds and more. "Hey Tails! I see something!" Knuckles said. In the distance he saw the Egg Carrier. "Hey that's the Egg Carrier!" Sonic said. "That old man is alive?" Knuckles asked. "Impossible. Must be an unused model." Tails replied. "Makes sense, but who activated it?" Sonic asked. "I don't know, we might as well take a look!" Tails replied. They flew over to the Egg Carrier. They made a safe landing.

Location: Egg Carrier mark III

Mephiles walked up to Metal Sonic. "A plane landed on the deck, should I go check it out?" Mephiles asked. "Yes, but take Silver with you Mephiles." Metal Sonic replied. He told Silver to come with him and they left off to the deck. They arrived. "Hey that's Sonic and co.!" Silver said. "Sonic?" Mephiles said. "Yeah, the future has been ruined a few times and he helped me restore it." Silver explained. "Oh, okay, let's ask why he is here." Mephiles said. "Fine with me." Silver said. They walked up to them. "Hey Silver!" Sonic said. "Good to see you!" "Yeah, this is Mephiles, a friend of mine." Silver said. "Nice to meet you Mephiles!" Sonic said. "Yes, but who are they?" Mephiles asked, pointing at Tails, Knuckles and Robin. "Tails is the fox! He is a genius! Knuckles is the red echidna! He guards the Master Emerald. And the red hedgehog is Robin, he can use the elemental powers of the Emeralds, but we recently fought Mecha Shadow and lost, and we all lost consciousness. Robin will regain it later because using the elemental powers use up a lot of energy." Sonic explained. Metal Sonic, Tails Doll, Metal Knuckles, Blaze and Omicron landed on the deck. "Sonic, why are you here?" Metal Sonic asked. "I'm fighting against Mecha Shadow with Tails, Knuckles and Robin, but we lost the last fight and lost three Chaos Emeralds." Sonic explained. "And why are Metal Knuckles and Tails Doll here? And who is the green robot?" Sonic asked. "Metal Knux and Tails Doll are helping me, and the robot is E-114 Omicron." Metal Sonic explained. "Oh, I see, great to see you all!" Tails said. "Yeah great to see you four too!" Tails Doll said. "Oh and we got two Chaos Emeralds here!" Omicron said. "Great!" Knuckles said "I shall guide you to your rooms here, that is if you want to stay here with us." Metal Knuckles said. "Of course!" Sonic said. Robin regained consciousness. "Ugh, where the hell am I?" He wondered. "We are on the Egg Carrier mark III" Tails said. "I'll explain everything to you!" Knuckles said. Knuckles explained what happened the last few hours. "I see, so we will stay here?" Robin asked. "Yup, I will show you your room Robin!" Knuckles said. Robin was guided to his room. "Wow it's awesome!" Robin said. "Yeah, we will have dinner in an hour! I'll show you around the ship if that is okay with you!" Knuckles said. "Sure." Robin said.

Location: Mecha Shadow's base

"Now I got three of my Emeralds!" Mecha Shadow said. "Now to find the other 4!" He said. A robot walked into the room. "My lord, we have located an Emerald in the Green Forest, shall I order the troops to go there?" The robot asked. "No, I want my enemies to get the Emerald, and when we know who has it, we will strike with all of our forces and kill the one who has the Emerald!" Mecha Shadow replied. "Yes, my lord." The robot said as he left the room.

Flashback

"Where is it! Where is that blasted robot!" Eggman asked. "We don't know sir." An egg pawn replied. "I want you to send all the troops and search for him!" Eggman ordered. All the troops were gathered and in the conference room. Mecha Shadow blasted through a door and Killed every single robot. "Now to find Eggman and kill him!" Mecha Shadow said.
