"Sonic, wait for me!"  A familiar voice rang out as Amy Rose chased after the blue hedgehog before her.  But the results were the same as always, after a dismissal Sonic ran off and left her behind in his dust.  Without an immediate reason to stay in one place Sonic's feet were calling for the road and that left Amy standing alone in a patch of grass looking off into the distance where he had ran.  Letting out a sigh she turned on her heels to head back the way she'd came.  

It wasn't like this was anything new.  Sonic didn't always abandon her but when he was feeling cooped up for too long he couldn't rest in one spot.  She understood that, it was even a good thing as this kept him on the move to deal with Eggman where ever he would strike next.  But still that didn't mean she wasn't left wanting when he departed.  "I wonder sometimes if Sonic would be happier if I just disappeared?"  At least then she wouldn't be there on his heels every time he stopped for a rest.  Maybe that would have been the best for both of them.  Dejected Amy walked with the sunset at her back looking to get home before nightfall.  

Then she felt the tap of a finger on her shoulder.  

Turning around Amy could see the shape of spikes coming off the head of the person standing in the bright sunlight before her.  Despite the harsh glare there was the color of blue and the shape of a hedgehog body.  So overjoyed Amy sprung off her feet and leaped into a hug.  "Oh Sonic, you actually came back for me!  I'm sorry if I was coming on too strong but I'm really happy you're... back?"  Feeling the figure her arms were wrapped around she noted it was a lot more solid than what she had expected.  Like she was hugging steel.  Turning her eyes upward with the sun shadowed by the frame of the one before her she could see electronic red eyes staring down.  "M-M-Metal?"  

"Target acquired."  Metal Sonic stated, his hand reaching out and grasping around Amy's neck.  The sun had dropped further below the hills in the distance and she could much more clearly see the robot monstrosity.  Shaped like her beloved Sonic but twisted in all the worst ways to be as deadly as possible.  Eggman's creation to rival Sonic in speed and strength.  Though it didn't make sense what he was saying to her of all people.

"T-target?"  Amy asked, scrambling to pull the steel claw off her neck.  Unsure as to why the machine would be after her over his usual enemy.  Maybe it was taking her hostage again?  Not willing to just let the robot have its way Amy used her free hand to pull out her hammer but it was quickly disarmed by Metal as well.  

"Applying further pressure."  The robot said and squeezed her neck harder.  Amy abandoned trying to use her hammar and grasped at the metal fingers around her throat to free herself.  It was no use though as the world was going black around her from more than the setting sun.  

"Sonic... Sonic help... me..."  Was all she could utter before passing out.  

When things became clear again Amy had no idea how much time had passed, eye lids fluttering as consciousness returned to her.  "Where... where am I?"  She tried to move but found herself strapped down.  Metal clasps were held over her wrists and chest, along with her legs at the ankles.  Looking down past her torso Amy could tell not only was she being held prisoner but also she'd been completely stripped down.  "What's happening here!?"  

"Oh, she's awake."  A male voice said, Amy able to turn her head a little and realizing she was strapped down to a table.  The room she was in was large, white and clean looking.  There were machines everywhere around her and only one other living soul.  "Pity for you, things would have been much easier if you stayed asleep."  

"Eggman!"  Amy shouted in rage, trying to pull herself up again but unable to loosen the bonds.  "You pervert, why am I naked!?"  

"Your clothes would have gotten in the way of the process."  Eggman explained, turning his back to her again to work on whatever it was he'd been invested in before.  

"Process... what are you talking about?"  Amy asked, very concerned seeing he wasn't keeping her in just some cell to use later as bait.  

"Not that you'll understand it, but I've finally figured out how to perfect my machines.  Behold!"  Eggman came over to the table to show her the head of a robot.  It reminded her of Metal Sonic's face, with the exception that it was painted pink and looked eerily similar to her own. 

"What... what is that thing?"  Amy asked frightened and Eggman flipped the head around to show that the inside was hollow.  

"The start of my greatest creation.  I've always had robots that were powered by my organic batteries you see."  

"You mean... the ones with animals inside?"  Amy asked, having seen more than a few of his creations that had an innocent creature in the center of the machine as a power source.  He usually cultivated animals for this purpose.  

"Correct!  So you do pay attention.  While it's worked well to help me produce my armies I've realized that there was a more... elegant design I could capitalize on.  Instead of going to the trouble of feeding a robot any old battery, why not fit the two together?"  

"I don't... understand what you mean but why do I have to be naked for this?  Where's my dress?"  Amy asked, finding his words no more comforting than her situation.  

"Oh it's somewhere, not that it matters.  Let's start loading up the machine."  

"The machine!?"  Amy asked and suddenly felt the table she was on slide backwards and then tilt forward until it had her standing straight up.  A glass tube slid over top of her and encased the table and her with it.  "Hey, what is this?  Let me out right now!  I don't want to help you with any of your weird experiments!"  As she shouted her voice echoed back to her and Amy was starting to realize she couldn't hear anything outside the tube.  She was sealed off completely.  The next time she saw Eggman he was back at one of his computers looking between her and the screen as something began to power up behind her.  "Hey... this is really scary, stop it already!"  

Those were the last words she was able to shout as the robot head designed to look like her own lowered down from above over her face.  The machines got louder around her and Amy could feel something hot pouring over her body.  It felt like it was sticking to her skin and sliding all over her from her neck to her feet.  She wanted to escape but as the hot stuff poured farther down she wasn't able to move her body.  Soon after there were hard impacts against her, rough ones that nearly knocked the wind out of her lungs.  The whole thing seemed to go on forever and all the while it was as if she was trapped in the dark inside this robot head.  

When the noises finally stopped she felt the table shifting again to lay her down.  She tried to get up but found she still couldn't, not even able to struggle anymore.  Like something heavy was keeping every muscle from moving.  Shortly after she could see again but it was through a green visor, as if she had some kind of electronic device pressed against her eyes that she was looking through.  

"Now for the real test.  On your feet, robot."  The scene before her shifted as Amy felt her arms and legs lift her up but not by her own command.  Standing upright she was looking at Eggman who was examining her carefully.  "We'll need a name for you, at least temporarily.  Robot, for now you'll be designated by the name Rose Bot to make things easy to remember."  Amy's head nodded in agreement to him without her telling her body to do it.  

"Hey, what's going on!?  What did you do to me!?"  Amy shouted but the words didn't seem to reach Eggman.  "Are you listening to me, stop this right now!"  

"Rose Bot, lift your arms."  Amy's body did as she was instructed.  

"Why... why am I doing what he says?"  

"Rose Bot, do jumping jacks."  Her body followed his command, performing these actions despite her trying to make them stop.  

"I'm scared... I don't like this."  

"Rose Bot, cease."  She stopped moving and Eggman nodded to himself.  "Fine work indeed, you'll make an excellent prototype to test this technology before I use it on the others."  

"Others?  Use what?  What's going on?"  Amy shouted, still trying to wrestle control from him.  

"Follow me now."  Eggman commanded and Amy did as she was told, her legs and arms moving to his beck and call.  Walking down a hallway Amy could see other robots, the kind he usually built, going various places and expanding his base around them.  Though they all stayed out of his way whenever he moved.  Stopping for a moment Eggman grinned and pointed.  "Take a look, Rose Bot.  I do excellent work if I say so myself."  Stopping her movements and turning to face the way he pointed Amy could see her body reflected back at her in a screen that was in a wall but turned off.  A perfect mirror for her to see herself.  

"I'm... I'm a monster."  Amy sobbed at the sight of her new body.  Her head, arms and legs were all plated with metal armor, her body covered by a metal dress designed to look like her normal one she always loved to wear.  She could see some sort of black under coating on her skin between the metal plates, likely the hot substance that had been poured on her skin before the metal portions had been installed on her.  "Is this what he meant?  When he said he'd take the robot and fit it to the battery?  Turning me into this!?"

"Come along now, we still have tests to do."  Eggman instructed and lead the way for her to follow.  He didn't seem to hear a word Amy said out loud, honestly she wasn't even sure if her lips were moving anymore.  So completely had this machine taken over her body that every movement and action was controlled by him now.  Maybe even her ability to speak.  "Here we are, let's see what your combat skills are like."  Walking into what looked like a hanger for a ship Amy could see several fat, humanoid figures across from her.  All classic Eggman robots she recognized and had smashed repeatedly in the past.  "Now pick up the hammer, we need to get started."

Searching around Amy found a metal hammer designed like her own she'd used in the past, grasping the heavy looking metal weapon and lifting it with ease.  She didn't feel any stress in her arms when she picked it up, such a feat was simple for her.  "I guess all these robot parts made me a lot stronger.  I wish I could use it to escape.  I wonder if Tails can fix me?"

"Now attack!"  Eggman commanded as Amy's thoughts switched from thinking of how to free herself to fighting.  Even though she hadn't wanted to engage in combat her mind becoming angry, with a burning desire to fight.  Lifting the hammer high Amy laid into the enemy robots, crushing them easily as they came at her.  Metal pieces flew and crumpled beneath her attacks, the hanger strewn about with robot bodies.  When it was over Eggman commanded her to cease and Amy stopped, adrenaline still pumping through her but leaving her more scared than excited.  

"I... I didn't do that!  I didn't do that!"  Amy shouted in her head, realizing how freely her body moved as she attacked.  She never consciously thought of how to strike the robots but her mind knew exactly how to wield the hammer.  As if her conscious mind wasn't necessary anymore for the machine on her to work.  "I... I felt it but I didn't do it.  Please someone make this stop.  I don't want this."  

"Not too shabby."  Eggman said, kicking a few pieces aside as he approached her.  Amy wanted to use that strength to attack him but her body simply wouldn't move a muscle against her new master.  His commands absolute.  "But against the riffraff even that weak girl you used to be could handle them.  Let's get you a real challenge."  Amy turned to see the one that had captured her approach.  Metal Sonic walked into the hanger and stood before her, glowing red eyes staring at her form.  Did he feel anything like she felt?  Was there a mind inside of his that was tortured like her own?  "Well get on with it."  Eggman ordered and even though she was programmed to respond her body still wasn't quick enough. 

"Acknowledged."  Metal said and struck Amy across the face, sending her to the ground.  It wasn't a punch or a stab, he just slapped her aside.  Lifting her head Amy looked up to see he was already above her and kicked her in the stomach, sending her rolling across the hanger floor.  

"It hurts!"  Amy shouted in her mind, surprised from the sudden pain.  "I can feel it when he hits me."  Despite the odd situation Amy tried to wrestle some control, picking herself up onto her feet and blocking another slap with her hammer.  When Metal stopped in surprise she pushed him forward to make an opening and swung fast and hard, sending him flying.  

"Whoa ho ho!"  Eggman laughed at the turn of events.  Watching as his creation sailed through the air and scratched up the floor as it drug across the hanger with its spikes.  "Seems we've got a contender over here.  Don't let me down now."  Metal Sonic looked at his creator's pleasure in Amy getting the upper hand on him and then took a runner's stance, charging her again.  

Amy blocked the attack with her hammer but it shook her off her feet.  She didn't feel any pain from the impact but was jostled when Metal swung around to strike her in the side.  "He's... not going to stop.  He... it... it doesn't hesitate to hurt me."  Maybe because it just saw her as another robot now but Amy had never been struck so hard before by the machine.  Riding the anger high the machine controlling her provided she tried to fight back, pushing as hard as she could.  But it was becoming painfully clear that Metal was still the superior robot.  Worse yet, no matter how much she fought and lost the attacks never stopped from either of them.  Even though each hit hurt her she never lost breath or energy, throwing herself again and again into the fight.  "He's too strong... I just want it to stop... how long do we have to do this for?"  The fight seemed to carry on forever until finally Eggman called for it to end, both fighters stopping in their tracks.  

"Hmph... she's better than the assembly line models but nothing that special.  I'm sure we'll find a use for her yet.  Metal, go back to your tasks.  Rose Bot, follow along."  Just like that it was over, the fight had ceased and both robots moved on to the next task they were given.  Amy followed with her head locked in place as she looked forward, wondering if some king of mistake happened during Eggman's experiment.  

"Am I supposed to be awake for this?  Wouldn't it have been better if I didn't know what was going on?  Please, if I can't be normal... if I can't be normal again don't make me watch it too."  Her cries for help were ignored as always, marching back into the room she'd come from as Eggman directed her to stand inside of a circle nearby.  When she did a glass tube lowered over her not unlike the one that had transformed her in the first place and pulled the metal armor pieces off of her body.  Just like that she was left to stand there with the minimal amount of robotics left on her frame, and then Eggman left.  

After the first few minutes Amy wondered what he had planned for her next, though as time went on she began to realize he wasn't coming back.  Panicking a little she tried to wiggle out of her bonds but couldn't even begin to move her arms or legs to do so.  As it was becoming apparent that there wasn't any escape Amy tried to fall asleep, at least to ignore this torture.  But a frighting realization was coming upon her.  

"I can't sleep."  She realized.  "I can't even close my eyes. I'm... I'm stuck like this."  Looking through the green visor the light of the laboratory never went dark.  Instead she was left just to stare across the room at a wall that never changed through glass that never moved.  After the first few hours she tried to think of anything to alleviate the boredom.  Then she tried to think of nothing.  Then she just began hoping for Eggman to return to free her from this.

She had no idea how much time had passed when the glass before her finally moved and Eggman gave her the order to exit, just happy to hear another voice and do anything at all but stand still again.  Even if her mind didn't have control over what that was.  Yawning to himself Amy thought it must have been morning, meaning he'd left her there all night while he got to sleep and rest.  If she wasn't so happy to have something to do she'd have been furious to know he slept while she didn't.  

"Alright Rose Bot, come over by the computer."  Amy did as instructed and stood next to the machine, Eggman moving around her and plugging in cables to her helmet.  "Hmm... let's see... well that's something, isn't it?"  Eggman said sounding intrigued.  "Not only are you still fully functional but the battery isn't damaged in the least!  All signs point to it being in perfect health, I'm a genius!  I may have mastered keeping both the machine and the battery in a constant loop of protecting one another."  

"You're a monster."  Amy thought.  "Those attacks hurt so much, how can I possibly not be hurt?"

"There's no internal damage, which is good or else this would have been a waste of time.  Let's check the exterior."  Getting up from his chair Eggman began to inspect her figure, Amy wincing mentally as she felt his hands grip all over her body.  Touching her in various places while able to sense all of it.  

"Why does he have to feel me everywhere?  Didn't that computer already say I was fine?"  Amy complained in her mind.  

"Hmm... it looks like the coating really did the job.  It's like a second skin.  Or well... just skin now."  Eggman said, pulling at the plastic like cover on her arms and legs.  Then suddenly she felt a hand grasp her breast and pull at it.  

"H-hey!  What are you doing you pervert!?"

"Hmm... a little artificial feeling but still moves like the real thing."  Eggman wondered aloud, his hand reaching down further on her body.  

"Wait, where are you looking?  Don't go just sticking your fingers where ever you want!"  Despite her protests he kept searching, his hand slipping between her legs and pressing up.  Amy mentally shuddered as she could feel his fingers pressing against her pussy, pushing it around and eventually slipping a finger inside of her.  "No!  No, I don't want to feel this!"  

"Well that's a surprise, it really is like a new skin."  Eggman said, pulling his hand back.  Moving behind her Amy felt him pull up her tail and press a finger against her ass as well, finding that opening was available too.  "It seems the process took closer to your body than expected.  That likely means it's not the only orifice that's still available."  Leaving her side Amy was concerned with the sudden revelation that not only was she no longer in control of her body but the body underneath was still available to be tampered with.  When Eggman returned he had a screw driver in hand and began to work on the helmet above her head.  She hoped that maybe he was going to pull it off, free her from this hell, whether letting her go or just making her no longer experience it.  Instead though she felt the plate over her mouth be removed from the helmet.  "Rose Bot, open your mouth."  

Her jaw opened, Amy feeling her mouth move for the first time since this had happened to her.  

"Well that's a surprise.  Rose Bot, say 'Hail Eggman'."

"Hail Eggman."  Amy heard her voice say out loud.  Now it was clear that even with her mouth exposed she could never speak what she wanted to say.

"Excellent!  You're just full of surprises, Rose Bot.  We'll have to give you an entire speech program to respond with.  Isn't this delightful?"  To her it was just reinforcing the nightmare.  The existence she wanted to end by any means.  "Say this is delightful, Rose Bot."

"This is delightful."  Amy repeated in a monotone voice.

"Hm... we'll need to work on adding some inflection.  But we'll handle that later."  Eggman returned to his seat, leaving Amy to look forward at another wall.  It was the closest thing to time to herself she could ever hope for anymore.  "Let's have a real test now and see if those organic parts are working.  Rose Bot, pleasure yourself."

It was terrible knowing what she was about to do, but had no will to stop it.  Horrified knowing that someone would be watching her, Amy felt her legs spread apart as her right hand moved between them and began to rub her pussy.  Her left hand rose to her breast and rubbed it, despite the feeling no longer resembling her skin she could still feel the sensations of pleasure when it was touched.  Worse yet she was already becoming turned on, her mind seeming to accommodate her master's wishes.  

"Please..." Amy thought, not wanting to do this.  "Don't... not in front of him... I don't want him to see me like this."  Her desires no longer mattered though, Amy feeling herself already become wet as her fingers rubbed inside of her pussy and her thumb pressed up to her clit.  Normally she'd never be able to keep on her feet after touching herself this intensely but her new body made it easy to maintain her strength.  Once she felt her climax finally coming on Amy's body clenched and shook as she came, her fluids from her excitement running down the new plastic like skin of her thighs.  When it was over she returned to just standing still and looking forward.  

"Interesting, she even reacted at the very end."  

"You made me do that and that's all you have to say?"  Amy thought, nearly sobbing at how merciless he was at playing with her body like a new toy.  

"Let's put it to a real test."  Eggman said and stood up, walking away from Amy and leaving her in place.  She didn't know what a real test was but figured it couldn't have been good.  It was strange, despite everything being so horrible when she was forced to pleasure herself she noticed then at least she had felt good.  Maybe the helmet was reinforcing the feeling of pleasure like it did with anger when it made her fight?  Some time later after all the noise in the rest of the lab ceased Eggman returned to her.  "Rose Bot, take this."  Holding out her hand Amy took what he'd finally made.  

"He can't be serious..."  Through the visor she was able to see the blue dildo he'd created for her.  All that time to make something this crude?  "What... what's he planning on doing with this!?"  

"Rose Bot, insert that into your lower orifice."  Unable to stop what happened next Amy felt as her hands moved down and slid the dildo into her pussy, it's size an issue at first but unfortunately for her the new robot arms didn't account for her own discomfort as just pushed harder.  "Well well, look at that.  It went all the way in.  Rose Bot, pleasure yourself with that for... the next hour."  

"An hour!?"  Amy shouted in her mind but didn't get to think long as her hands were now working the toy into her, sliding it up and down inside of her pussy.  The invasion was enough to jumble her natural thoughts as it dragged against her inner walls.  Nodding at his work Eggman left Amy alone in the lab as her hands continued to use the toy. 

"It's big... I don't want it."  Amy thought as her body was forced to masturbate, taking the toy into her body and slipping it in and out.  The color unfortunately reminded her of Sonic and with the reinforcement of the machine on her head she found her mind drifting to thoughts of him.

At first it was rough, even with her body prone to excitement, but once the thickness was no longer an issue Amy stopped letting thoughts of resistance get in the way and just accepted it.  With one hand she continued to use the toy, her other moving to her breasts and able to tease her nipples, which even through the plastic coating felt as sensitive as ever.  Possibly even more as her body was purposefully driven to feel arousal.  As before time seemed to pass without her able to keep track, long past her caring how many times she shook with each orgasm that hit her body.  When it seemed she wouldn't be able to keep her sanity through all the stimulation it suddenly stopped, her hands returning to her sides and the toy sliding out of her pussy onto the floor.

The hour was up.  

Just like that the excitement began to fade, leaving Amy to mentally recover from everything that had just happened.  It was awful and humiliating and just drove the point further that she wasn't viewed as a woman anymore but instead a toy to be used for this old man's desires.  Still, despite it all, that was the best she'd felt since this happened to her.  

"If I can't sleep... if I can't die... just make me feel good, till I can't think anymore..."  Amy thought, wishing to be free of this.  She didn't know how much time had passed until Eggman finally returned, looking at the results on the floor beneath Amy.

"Still intact I see.  Well if I can't use you for combat maybe you'll have other uses."  Eggman grinned evilly at her, Amy horrified to think of what he could be imagining now.  "Get a mop from the supply closet and clean your mess up, then return to your pod.  We'll work on your refined programming tomorrow.  I've got better things to do tonight."  Just as quickly as he came Eggman was gone, Amy's body already in motion to do as he commanded.  She didn't know where the supply closet was, but her other mind that controlled her did.  Grabbing a mop and bucket Amy went to work cleaning up the puddle of excitement she'd left on the floor from her forced orgasms, looking at the mess she'd made and thinking if nothing else at least her friends couldn't see her like this.  Maybe it was better to die in this machine than have them find her like she was now.  

Finishing her chore Amy put the mop away, then returned to her new home, picking up the blue sex toy and returning to her pod.  The glass cylinder dropped around her, the lights stayed on and Amy stared forward as she awaited her next nightmare to begin.
