Episode 13

Previously on Sonic The Hedgehog - Chaos on Mobius...
Sally's robot double arrived at Freedom HQ, but 'she' didn't harm Amy or Nicole in anyway. In fact she joined them in their game, although Nicole suspects something strange... While on the ARK, the pot plant that Tails found with Chaos Emerald, grew to form a small rose with large vines that freed Tails from the control of the 'Artificial Chaos'.
As TodStar got reaquainted with Vector, Knuckles introduced him to the rest of the Chaotix before travelling to Robotropolis.
Meanwhile, dispite a warning from a local (who was apparantly royal), Shadow and Gamma entered the abandoned castle, hoping to find a Chaos Emerald. Little did they know that one of Eggman's robots that was bound to the local legend was waiting for them. "I AM OMEGA, THE ULTIMATE E-SERIES ROBOT." While Gamma was fighting Omega, Shadow confronted Chaos Dracula, the evil spirit who dwelled within the castle. What Shadow didn't realize was that Chaos Dracula had possessed someone close to him... "Rouge?"
After TodStar and the Chaotix arrived outside Robotropolis, Eggman revealed his latest acheivement... "My very first victim of Roboticization: Sonic the Hedgehog!"

Chapter Thirteen: "Damsels" in "Distress" (Part 4 of Robot Rampage!)

"Sonic..." Said a worried TodStar, while looking at a Roboticized Sonic.
"Oh hohoho! He goes by 'Mecha Sonic', now." Eggman pointed out. "Princess Sally was perfect bait to lure him here!"
"Sally's here, too?" Asked TodStar.
"You better not have hurt her!" Warned Knuckles.
"Oh. You see, with my new pet, I don't respond well to threats." Eggman pointed out. "Mecha Sonic?" Roboticized Sonic then smashed into Knuckles, sending him quite far!
"Chaos Spear!" TodStar shouted as he threw an arrow of Chaos Energy at Sonic, but the only effect it had was get his attention. "You guys go find Sally and the girl! I'll deal with Sonic!"
"Not alone you're not!" Yelled Vector as he ran to help TodStar. "I'm givin' you a hand."
As Mecha Sonic charged at TodStar & Vector, the scene changed to Omega charging at Gamma within the castle of Mercia. Gamma managed to stop Omega's charge with a high-powered laser beam.
"Let Rouge go. Now." Shadow ordered Chaos Dracula, while readying a Chaos Spear, as Chaos Dracula had possessed someone close to Shadow: Rouge the Bat.
"*giggle* Do you really think it will be that easy?" Chaos Dracula replied in the seductive female voice, but it slowly transitioned into a demonic male voice. "Besides, that Chaos Spear will merely hinder you, not help you."
"We'll see about that." Said Shadow. "Chaos Spear!" Shadow threw the Chaos Spear at Chaos Dracula, but he merely made a soothing sound. "What?"
"*chuckle* Thanks for the refill, Shadow..." Chaos Dracula replied, getting closer to Shadow. "...but I sense a large amount of Chaos Energy within you..." Chaos Dracula then licked Rouge's lips, then raised her mouth to Shadow's ear. "...and I want it." Shadow then stomped on Rouge's foot, which caused Chaos Dracula to fall back and allowed Shadow to use Chaos Control without getting grabbed.

Meanwhile, back on the ARK, Tails had just awakened to find a Mobian-like girl around his size lying next to him. She had a rose on both sides of her head, her hair seemed like it was made of leaves (in fact, all of what she wore looked very natural. In more ways than one!).
"Uhh... who are you?" He asked her.
"Oh, I'm sorry. My name is Cosmo." She replied with a sweet young voice.
"Well, I'm Miles Prower, but just call me Tails." Said the fox, as he and the girl sat up. "Forgive me, but I've never seen a Mobian like you before."
"Mobian?" Cosmo repeated, not understanding. "I came from Planet Wisp."
"Planet Wisp, huh?" How far away is that?" Tails asked her, but she just shrugged.
"The Chaos Emerald... this is what has sustained me all this time..." Said Cosmo, holding the Emerald up high.
"Wha?" Tails thought. "C'mon, I'd better get you and the Chaos Emerald back to Freedom HQ. I think I saw a teleporter on the way through here." Tails and Cosmo soon found the teleporter Tails mentioned.

Back in Freedom HQ, Amy, Nicole and 'Sally' had given up on racing, and decided to take a break.
"Wow, you were on fire, Sally!" Amy pointed out.
"Thank you, Amy. I did tear up the track, didn't I? As opposed to someone else..." 'Sally' replied, smirking at Nicole. Nicole had noticed the way 'Sally' was acting, and she did not like it...
"Pardon me, Sally, but may I speak to you alone?" She asked 'her', and 'she' nodded. 'Sally' and Nicole then entered the lab, where they could be alone.
"What's wrong, Nicole?" 'Sally' asked her.
"I know you're not the real Princess Sally." Nicole replied, to which 'Sally' just shrugged.
"So I've turned over a new leaf." Said 'Sally'. "How did you come to the conclusion that I'm not the real Sally?"
"I scanned you after you sat down with myself and Amy, and I sensed underneath that fur was nothing but metal and electricity." Answered Nicole.
"So? What are you gonna do about it?" 'Sally' asked, and Nicole responded with a Spin Dash, which sent 'Sally' flying out of the lab, and into a bookshelf that dropped many a book, but a weird-looking ring came out of one book.
"Nicole? What's going on?" Amy asked the former Gizoid.
"That's not the real Sally, Amy."
"What?"
"She is an impostor created by Dr. Eggman."
"You don't have to tell me twice!" Amy said as she got out her Piko Piko Hammer.

Meanwhile, deep within Robotropolis, the real Sally was trying to sleep, but it was hard for her in the capsule. Suddenly, she heard footsteps approaching. When Sally turned around, a pink echidna was looking at her.
"Shh." She said quietly. "I'm gonna get you outta here."
"Who are you?" Sally mouthed before the capsule opened.
"My name's Julie-Su." The echidna whispered. "Just keep quiet Princess, and stay right on my tail."
"Okay, but just call me Sally in the future."
"Noted. Now c'mon."

Back in the castle of Mercia, Shadow and Gamma were still struggling to fight off both Omega and Chaos Dracula.
"Chaos Spear!" Shadow shouted while throwing an arrow of Chaos Energy at Omega, that not only hit the robot, but it also seemed to shut down.
"Omega! Chaos Blast!" Yelled Chaos Dracula as he released a beam of Chaos Energy from Rouge's body, and aimed it at Gamma. Gamma was too slow to get out of the way, got hit by it, and was sent flying, suffering extreme damage.
"Gamma!" Shadow cried, as Chaos Dracula launched another Chaos Blast at Shadow, but missed thanks to Chaos Control. Wherever Shadow showed up, Chaos Dracula would launch another Chaos Blast, but kept missing.
"One of us will wear out eventually, my dear Shadow *cackles*" Chaos Dracula pointed out before Shadow showed up behind Rouge.
"Hmph, you're right." He replied before Chaos Dracula unleashed another Chaos Blast at Shadow, but again, missed. "And the one who will wear out first will be you."
"We'll see about that. Chaos... Blast!" Chaos Dracula challenged as he was about to unleashed another Chaos Blast, but nothing happened. "What? Chaos BLAST!"
"Hmph. I think it's safe to say you're out of power." Shadow pointed out.
"No! NO! I can't lose this body now! NOOOOOOO!" Screamed Chaos Dracula as he slowly left Rouge's body, letting her not only rest, but her original clothes she had on before being possessed returned: A yellowish-brown tank-top, dark blue jeans, brown worker gloves (like in Sonic Rivals 2) and leather boots. "YOU WILL REGRET THIS, SHADOW THE HEDGEHOG!" Chaos Dracula warned as his spirit flew up higher. As Chaos Dracula left the room, the armored hedgehog was watching from a window.
"Hmm... This may prove to be quite the challenge, once I confront him..." He thought.
Shadow then ran over to his fatally damaged robot friend.
"Gamma! Gamma, are you okay?" He asked it.
"NEGATIVE." It replied. "MY SYSTEMS ARE NOW BEYOND REPAIR. I AM SORRY I-I-I COULD N-N-NOT HELP YOU FURTHER-THER-THER, SHADOW."
"Gamma... don't leave like this..." Shadow begged his robot friend.
"I AM SORRY, SH-SH-SH-SHADOW." Gamma stuttered back, now struggling to speak, so he activated a light which it used to talk to Shadow: "REMEMBER MARIA'S WISH, SHADOW."
"*sniff* I will." Shadow replied. Gamma then lit up the wall behind him with one last comment: "...GOODBYE." After Shadow read that, the light Gamma used to speak faded, and so did the light from it's eyes. "Goodbye, Gamma." Shadow said as he closed his eyes, trying to hold back his tears. But he also noticed Gamma's chest plate opened, revealing a Chaos Emerald. "Th-the Chaos Emerald!"
"Shadow!" Cried a familiar female voice behind him.
"Rouge?" Shadow asked while turning around and experiencing a hug from his friend.
"Shadow, I'm so sorry! I wanted to stop him, but I couldn't. *sob*" She tearfully said.
"*sniff* It doesn't matter now, Rouge." Shadow replied. "What's done is done. Can you still command that robot?" He asked while pointing at Omega.
"I think so." Rouge replied while approaching it. "He was bound to me before I got possessed. Omega, can you hear me?" Omega's eyes suddenly lit up, indicating that it was operational.
"SHADOW." Omega said, getting the black hedgehog's attention while getting to his feet. "GAMMA SENT ME ALL OF THE DATA HE HAD AQUIRED WHILE TRAVELLING WITH YOU. YOU MAY NOW CONSIDER ME AN ALLY."
"Hmph. Why should I?" Shadow asked, giving the large robot a cold look.
"FOR STARTERS, I REMAIN BOUND TO ROUGE THE BAT." Omega replied. "IF SHE WILL JOIN YOU ON YOUR JOURNEY, SO SHALL I."
"Will you, Rouge?"
"Sure thing, sweetheart. I could use some Mobian company."
"SECONDLY, SINCE I RETAIN ALL OF THE INFORMATION ABOUT YOU THAT GAMMA SENT TO ME, I NO LONGER HAVE THE DESIRE TO MAIM YOU."
"Hmm... Very well, Omega. You may join me."

Back within Robotropolis, Sally and Julie-Su were trying to sneak out, but they were stopped by Metal Sonic.
"Eep!" Said Julie-Su.
"Metal Sonic!" Sally cried as Julie-Su got out a blaster she had. But before she could use it, a glove with spikes on it smacked Metal Sonic away.
"C'mon, right this... way." Knuckles said before he noticed Julie-Su, and trailed off. Julie-Su was just as far away as Knuckles was when she saw him. In fact, they may have been in that same faraway place, all alone...
"Uhh, Knuckles, Julie-Su?" Sally said, bringing the two echidnas back to Mobius.
"Uhh, right. Come with me." Knuckles told the girls. "You guys can handle Metal Sonic, right?"
"Consider it done." Espio replied, unaware that Metal Sonic was right behind him.
"Espio, heads up!" Yelled Mighty before he curled up into a ball and blocked Metal Sonic's attack.
"Hmph. Impressive." Espio pointed out as Mighty stood back.
"Yeah, my shell's pretty much inpenetrable." He replied.

Back outside, Vector was out cold, while TodStar had used his Chaos Boost to fight Mecha Sonic, but he was exhausted.
"One advantage to being a Robian? I can never get -as you would say- knackered." Teased Mecha Sonic.
"*huff huff* Sonic, for the last time, mate... *puff huff* please... stop... *groan*" TodStar tried to get out, but eventually lost his Chaos Boost, and passed out.
"Nice knowing you, TodStar the Echidna." Said Mecha Sonic as he was charging up a beam-like attack. But before he could release it, he felt a laser hit him in the back. Turning around, Mecha Sonic saw Sally, Knuckles and a pink echidna holding a blaster.
