You should not have sat on the mech's shoulder during his visit to the mad science lab on the ship. If you weren't in the wrong place at the wrong time, you would not be in this weird situation.

This was way too strange...

Megatron

"I must admit (Y/N), you are becoming quite the marksman. Or perhaps it should be markswoman. It is hard to say considering our current circumstances." Megatron sat to the side, watching in your body as another shot hits the target dead center. 

Right after you and the leader of the Decepticons apparently switched conscious', the scientists did tests to see if it was reversible. The good news was that it was indeed possible to undo what happened, but they did not know how or how long it may take.

You lower the giant blaster, looking your handiwork over with red optics. You then smile, the sharp denta that usually belongs to the Decepticon warlord showing. "Why thank you. I had a good teacher." 

Megatron smirks, "Good!" The human-female-mech's grin then widens, "Now shoot my fushion cannon." 

"What?" You were slightly surprised that he would allow you to do this. 

Megatron leans back, getting comfortable. "You heard me, (Y/N). Prove to me that you are worthy by wielding my weapon." 

You look towards your arm and at the massive (yet lighter than you originally thought) cannon. It would give a fair kick and you were uncertain how to activate a weapon that was mounted onto you instead of one you simply held. 

Stepping into place, you look towards your mark once again. It is relatively far away and you are not certain whether the shot could travel that far or if it would just disintegrate something before it. 

Deciding to just do it, you glare at the bullseye with slanted optics, concentrating. Your arm is lifted, the cannon with it. 

You aim it...

...and form a fist...

...it glows a purple hue...

...and the blast shoots out of the weapon like an explosion.

You lower your arm, optics widened slightly. 'Was this truly how powerful Megatron was?' 

Sitting straighter, Megatron smiles at the smoking target- half of it nothing but tiny pieces or melted. "Well done. It seems you no longer require me as teacher." 

"On the contrary. I think I'll need your help more than ever..." You face the human-bodies warlord fully, optics shining with determination.

"I want you to teach me everything you know. Teach me how to fight. Teach me the skills I need to be able to go up against the best warriors and stand a chance."

Megatron gets up and stands a close to you as possible, a hand resting on his chest as he bows slightly. "My dearest (Y/N), I would be honored. But know..." his smile becomes smug, a bit.of.his wickedness showing through.

"I won't make it easy." 

Starscream

"SCREEEEEEEEEE!!!!"  

You grip the sides of your helm, trying to block out Starscream's shrill, mortified shriek. "Starscream!" 

"How could this be happening!? I didn't add anything to the experimental synthetic energon formula that could've caused something like this!" Starscream pulls at his (h/c) locks. 

"How sure are you?" you ask, cringing as your voice cracks. 

"Very sure! Stop undermining my expertise!" He folds his arms and glares. "We need to find a way to reverse this. I do not want to be stuck like this forever." He wrinkles his nose.

"What's wrong with being human?" you ask, slightly hurt that he felt that way. 

Starscream instantly regrets his words, realising the other meaning that it could insinuate. "That's not what I meant (Y/N). You are a wonderful femme and I am happy to have you as a companion." 

A warm sensation made its way through your body, your wings fluttering. The guy knew how to get himself out of trouble. 

The mech (in your body) climbs onto your servo. "Now, since I am too puny to use the equipment, you will have to work with it while I instruct you on what to do." He makes himself comfortable. 

You groan and drag your healed pedes to where you needed to go.

---------------------

Starscream was in his element as he lorded over you. Despite his ordering, however, you had to agree that he did try his best to explain how everything works in case you need to use it in the future. 

"Do you see the centrifuge? Put the vile into it." He tracks across the table's surface, hands folded behind his back as he watches as you do as he says. "Excellent. Now turn it on. Make sure it is at its highest setting." 

Once again you do as he commands of you. With a flip of a switch the piece of equipment is turned on and starts spinning.

"That should do it. That is, of course, if my calculations are correct." Starscream places a hand to his chin. 

"And if it isn't?" 

"Then we may never turn back or meet a terrible demise as soon as we consume it," he states simply.

You prayed neither would happen. 

"But before then, clean up," Starscream smirks and waves a hand, then returning it to its folded position behind him. 

You huff and glare, not in the mood to fight. Picking up some empty viles, you go to put them away. As you walked, you did not notice the wire across the floor. The point of your pede gets hooked in it and you trip with a yelp. Soon you find yourself tumbling to the ground. The viles fly through the air and shatter on the ground next to you. 

"What the frag did you do!?" Starscream yells as he runs to the edge of the table. 

You did not answer him; just writhed on the ground in pain as an agony like no other flared through your now bent wing. 

Seeker wings were sensitive, you knew, but this...

"You fool! I'm going to have to live with that now!" Starscream freaks out, completely ignoring the fact that you were currently in anguish. 

Biting your derma, you slowly get up. Tears pricked at your optics as you grunted. You limp to him, taking up. "I-I'm sorry S-Starscream. I didn't mean it..." 

That tone... It reminds him of so many horrible memories.

His hard gaze softens. "It's alright (Y/N). Let's try and get changed back so you can be relieved. At least I know how to handle damaged wings by now."

"H-How so? The war?" you place him down. 

"The war...and my many failures." 

You look back at the wings and, for the first time, notice the faint scars from abuse. 

Soundwave

As you woke up you felt strange. Your limbs felt like lead, and your body felt different.

The first thing you notice is that you are in Soundwave's quarters. The thing is, you weren't in your bed, but rather on the berth. The moment your eyes were fully open, vootage from around the Nemesis flashed across your vision. 

"What the-"

That was not your voice...

You jolt upright, immediately feeling clanks and creaks where there should be none. You look down, pinicking as you find not your own body, but Soundwave's frame instead. Turning, your eyes fall on your bed and, on your bed, your own form sleeping.

You try to stand up, but fail miserably when you fall down to the floor.

Immediately, your body jolts awake, probably from all the commotion. Its head turned to you, seeming confused just as you were when its eyes fell on you.

Immediately your body's eyes widen in horror. Its face pales and the mouth hangs open.

It springs out of bed and tuns towards you. You were running towards you...

The body stops in front of you, waving its arms in the air.

You looked at the body, trying to figure out what was happening, while your vents kicked in overdrive. 
At that moment realisation dawned on you.

"Soundwave?"

The man-woman turns even paler as he flings his arms wildly.

It is then that, Rumble, Frenzy, Lazerbeak and Ravage almost flew into the room, looking ready to fight. 

"What's wrong, boss?" Frenzy questions, all of them looking at you. Ravage let's out a growl.

"How did t-this happen?" you ask. For a moment it seems like Lazerbeak forgot how to fly. The twins were struck dead in their spots and Ravage's growling got caught in his throat.

"B-Boss?" Rumble gawks. This is the first time the twins heard him speak besides over their bond.

 Soundwave comes up to him in your body. "It is (Y/n). Our bodies seemed to have been switched."

You were looking at him, dumbfounded."This is what you sound like?"

Soundwave turned to you, irritated. He wanted you to stay quiet, you knew. You were about to say something when you decided to just mute yourself.

Rumble looks at both of you, moving a digit from the one to tge other, "I can't keep up with all this drama..."

"At least we are not the cause this time Bro!" Frenzy grins. Ravage swats him over the helm with his tail.

"Let us stay calm. I will have (Y/N) help me to find a way to reverse...this." Soundwave refers to himself. Catching on, you pick him up and head to his usual workstation. 

Immediately both of you start working. You were however slightly distracted. Now you know what Soundwave sounds like when speaking without recordings; without speaking with a robotic static or in but a whisper as he did when in holoform. It was a smooth, kind voice- so much so it caused your heart to, or spark, to skip a beat.

Knockout

"Nope! Nononono!" Knockout (in your body) paces around, panicking slightly. "Today is check up day..."

You lift an optical ridge, arms folded in a very Knockout way. "Check up day?" 

"The vehicons are all coming in for their medical examination! I can't do it while looking like this!" He throws his arms into the air. 

"Relax, I'll just do it for you." You place a servo on your hip. "How hard can it be?"

"Do you even have the slightest idea of how to look for any symptoms of cosmic rust, viruses or spark failure!?" he grips his head. "Do you know how to work the equipment?" 

"No..." you admit. "But I am willing to try if you'll help." 

"How!?"

You think for moment, a plan forming...

-------------------------

In came the final patient: vehicon G-4rY or simply Gary.

The vehicon before you seemed quite nervous as you scanned him. He was the last one on your list of check ups- the others all done and dusted. It was thanks to your idea of having Knockout call you using your phone so he could guide you that helped you get through the masses.

The beam moved over his frame as you searched for any signs of ailments. The light stayed green until it reached his shoulder.

Frowning, you read the findings aloud so Knockout could hear you over the phone, "It seems there is a slight...circuitry malfunction in the...left...secondary hidrolic." You look up at him and grin.

"Alright. You need to give him an anti-rust injection and prescribe him some antibiotics which he'll need to take for three cycles." Knockout whispers over the line from his spot under one of the berths.

You nod once then turn your full attention to Gary. "Well, it seems you have a slight infection forming in your joint. I'm going to prescribe you some medication which you'll need to take for...three cycles. Before you go, however, I need to give you a shot." As you say it, you take the syringe and ready the medicine.

"Will...it hurt?" Gary asks with a small voice, looking like a scared little boy. 

You tapp the syringe, knowing exactly what to do after watching Knockout do it a hundred times before. "No, not if you're brave." 

"W-Well... I'll be brave then." he states, determined. 

Within a blink of an optic you allow the needle to.penetrate into the soft mesh of his protoform and inject the antibiotic. "There, all done! You're good to go." You smile, catching the soldier off gaurd. 

Slowly, he gets up and makes his way to the door where he stopped to look back at you again. You wave, him reluctantly returning the gesture and exiting. 

"..."

"You're way too nice," Knockout says as he comes out from his hiding place. 

"You mean you're too nice," you smirk and place a hand on your hip. 

Knockout huffs, then smirks back. "Oh, by the way, you're out of minutes." He takes out your phone, waving it around. 

Breakdown

*Warning: Sorry not sorry! Breakdown is asking some embarrassing questions about the body! Your body in particular!*

It was awkward. So, so very awkward. The most awkward thing you have ever experienced. Especially when Breakdown had to go use the bathroom in your body.

The human-girl-mech did not exactly know what to do since certain parts were lacking...

"You know, human parts are really similar to Cybertronian parts," Breakdown muses as he smirks.

"Breakdown, don't you dare! It's already freaky enough that I had to help you which means your optics saw me...!" You slowly cut yourself off, not wanting to think back anymore.

"Relax (Y/N)! I used to be a medic's assistant." He reassures you.

"And did you see any naked femmes in that time period?" you inquire, glaring with your single optic. Breakdown just stays silent, red pushing up to his cheeks.

You huff and sit down on the berth. You don't know what to do. 'What if Breakdown is called out on a mission? You can't go out into the field!'

'What if you suddenly received your period? There's no way you're explaining how everything works!' 

'What if you accidentally stepped on him-er-yourself?'  

Quickly you take him up and place him higher up. The woman yelps in surprise, not used to being lifted up like this- especially not so suddenly and so roughly. "Sorry," you apologise. 

He just caughs and waves you off. "Now I know what it feels like," he jokes.

Breakdown then absent mindedly starts inspecting his new body. He never knew it would feel so different being human and female. "Hey (Y/N), isn't it annoying to have to change clothes every few hours? And to have different sorts of clothes for different reasons?"

You humm, "Well, I never really gave it any second thoughts. I've been doing it for so long it's just a normal thing to do."

"And what about having to brush out your hair?" He tugs at a few strands.

You shrug and lay down on the berth (which was pretty comfortable). "That's a bit annoying at times, but you gotta do it or you'll have a rat's nest on your head." 

The mech-girl tugs at her shirt. "Do you find it hard to do things with...uhm...boobs?" 

Your optic rapidly opens to find Breakdown staring down at his- your- cleavage. 

"..."

"..."

"Breakdown, that's real perverted."

"So it's a 'yes'?"

"I will squish you."

"So it's a 'no'."

"Breakdown!"

Predaking

You woke up finding yourself lying on the floor, stomach touching the cold surface. To top it all off, the moment you opened your eyes, your body was standing in front of you.

"(Y/n), I know this looks troublesome, but it seems like Shockwave's experiment lead to our bodies being switched..." your body speaks.

You are extremely confused and a tad bit panicked. You try standing up, but your body doesn't obey the way you want it to. Looking down, you discover Predaking's beast form. You attempt to speak, but all that comes out is a small whimper.

"(Y/N), listen to me. It's Predaking," your body, Predaking, places his hands on his chest. "I need you to calm down, alright. Shockwave is working on a solution as we speak."

It is only now that you realise that your vents were working extremely hard.

You get up.

'KISHHH!' 

Both you and Preda turn to look behind you at the shattered glass of an old energon cube. You had accidentally knocked it down, courtesy of your tail. 

'A TAIL?!?!?!'

Panic takes hold of you again. Rushing forward, you attempt to get away from the new appendage, bumping more things over.

Predaking flails his arms in an attempt to get your attention, failing miserably. "(Y/N)! Transform!" 

But you did not know how to.

Things continue to clatter onto the ground as you rammed into every piece of possible furnishing in the room. 

"(Y/N)!" Predaking drops down as your powerful tail swoops over his head, almost decapitating it. The girl-mech stays low, tucking and rolling in a means to escape the rampaging Predacon. 

Everything finally comes to and end when you plow into a wall, knocking yourself unconscious from the force. You grow limp, losing all signs off life.

Predaking rushes towards you, panic-stricken. A little bit of energon trickled down your snout, causing him to immediately call Shockwave on your cellular device for assistance.

'He only hoped that you were alright.' 

------------------------

Shockwave came to your aid. Though he was no medic, he managed to come to the conclusion that you were alright- the hit simply caused some of the forehelm armour to cut into the protoform beneath it. 

He reassured Predaking that everything was alright and that you would soon return to normal. Then he left to do some science-y stuff, leaving Preda to wonder what he could do to occupy himself. 

He found your cooking equipment.

_______________________________________

After a good night's rest​​​​​​ (and probably thanks to dump luck) the two of you once again found yourself in your own body.

You woke up drooling with your legs over the edge of your bed. A headache followed. This caused you to reconsider ever getting drunk. Hangovers must not be fun...
