Chapter 1

The sun had long since set, and I was walking home, alone. It was a long day at the post office, and I was eager to get home and eat some muffins. But unbeknownst to me, an evil stallion was lurking in a nearby alley, finishing up with his latest victim.

I passed the alley in question as quickly as I could, hoping I wasn't being followed. But I was being followed, and before long he pounced on my and dragged me into an alley. I tried to call out for help, but he slapped me, putting duct tape on my mouth and pinning me to the ground. I kept struggling, trying to yell through the tape, but he knocked me out.

When I woke, I was in a cold room, a basement of sorts. I saw a stallion with with a grey coat, and i blue and white striped mane and tail. He was good-looking, but my situation was more important. I spoke muffled words, a look of fear in my eyes. “What was he going to do to me?”

Smirking, as if answering my question, he grabbed a cat-o-ninetails whip with hooks on the end, and whipped me. Still struggling, I winced in pain. Then he spread my legs and Slapped my plot hard.

A tear began to trickle down my cheek. I usually liked to company of a stallion, but he didn’t have to be mean about it! He laughed evilly, and asked me my name. I tried to answer, but my distressed words were muffled by the tape from before. He ripped off the tape and asked again.

"D-D-Derpy Whooves," I stuttered, sobbing. "Wha-wha-what do you want from me?"

He smiled. "You'll find out later, miss Whooves. Answer me one last question. Are you a virgin?"

Sniffling, I did my best to compose myself and answer. "Well... no. I see ponies fairly often actually. In fact, if you had just asked in the first place, i probably would have been fine with it."

Smirking, he penetrated my pussy and laughed. I was barely holding back sobs at this point.

"Heh. Tight little slut, ain't yeh?" I was now openly crying, hoping that it would be over soon.

He thrusted hard enough to penetrate my womb in one thrust, then he slapped my plot, which  left a bruise.

It hurt, and he knew it. I could tell he was getting enjoyment from my pain. But I wouldn't give him the satisfaction. I had to stop crying. "Why would somepony do this!?"

"Correction, miss Whooves. Why would a changeling do this? Hm?" He transformed into his true changeling form, then slapped me some more. I felt slightly relieved, knowing that nopony would do this, but that didn't change the fact that I was being raped.

Then, a realization hit me; I had never had sex with a changeling before! I knew what to do! Struggling to move in my chains, I pulled the changeling into a kiss, hoping to surprise him, but to no avail. He kissed me back, then bit my lip, drawing blood.

This creature was devious, but i was more so. I was determined to enjoy this if it killed me. I continued the kiss, the taste of blood in my mouth.

He stopped kissing me, and pulled away, then he snarled. "The hell do ya think yer doing, Whooves?".

He then chopped of my left wing. It hurt, but it was nothing I hadn’t felt before, in my adventures with The Doctor.

I realized then that this creature indeed was going to kill me. Holding back a cry of pain, I instead let out a moan of pleasure. "You really know how to turn a mare on, don't you?”

He growled, then chopped off her other wing. "Nice try, Whooves, you aren’t fooling me!”

The pain was truly gone this time, possibly because of shock. The wings didn't matter, Doctor Hooves and Twilight could help bring them back if i survived this. I let out another moan.

He smiled. "Perhaps it's time I bring out the blue flashy weapon." He took the weapon out of a bag and pointed it at her. It was a sonic screwdriver!

"Where did you get that? Oh, it doesn't matter. It doesn't work on organic beings anyway."

He chuckled. "Oh so you know what it is? Are you an offworlder? Master will be pleased!"

"Oh no, I know a stallion who is though," I explained.

"Is it the evil One known as....the Doctor?" He smirked, then shoved the device up my plot. It really did feel good this time. "Yes, and he will take you down!!"

"How? When I have encased him in stone?" My face went rigid. So that's how he got it. Then a smile crept across my face. "The Doctor has friends in many places. I'm sure that he will escape, although I might not be here when he does."

He facehoofed, then started thrusting inside my marehood at maximum speed, really hard

"Ohh~" I was starting to enjoy this, although I shouldn’t be.

"Besides,” he said, “by the time he escapes, if he escapes, you'll be my submissive breeding slut." He let out another evil snicker. "Maybe, or maybe not," I said, trying to keep my hopes up. He then penetrated my womb again, and he took a knife out and started slashing me up. It hurt really bad, but also felt good. I don't know what was coming over me, but I needed to get out of this. I just needed to figure out how.

Then he came. At that moment, he came inside her womb, and he started strangling me.

The changelings extra-terra fluid mixed with my blood inside of me, sending me reeling into pain. Buck! I was The Doctor's companion, I could get out of this! But how??

I felt him laying eggs inside my womb, laughing evilly. "Unlike other changelings, i feed off of pain. So thanks for making me stronger, Whooves!"

I took the chain that i was bound with, and choked the changeling. While he was momentarily distracted, I bucked the creature off of me. I didn't know what to do next.

He growled, pissed off to the nth degree. "YOU'LL PAY FOR THAT, WHOOVES!"

I had to think on my hooves. MY SADDLE BAG!! I reached into it, grabbing the spare sonic screwdriver that the doctor gave me, and used it, disabling the one that the changeling had and killing the lights. then for good measure, I activated the cloaking device embedded in the watch that I wore.

He turned the lights back on, then laughed. "You idiot. The chains are floating." He punched me right in the face, and saw blood and a few teeth fly out of seemingly nowhere.

The changelings fluids were still inside me, mingling with my blood. At that moment, I felt a surge of strength as I broke from the chains, punching the creature square in the face. I must have been temporarily strengthened by the alien DNA in my body. I wasn’t questioning it.

He fell backwards, then he sighed. "Look, miss Whooves....you probably think That I’m doing this just to be evil. But as i said before, I’m feeding off your pain...and..well....I'm the last of my kind...trying to find a willing breeder isn’t easy...trying to rebuild the changeling empire isn’t fun....it isn’t MY fault that i was born to cause sexual pain! I...I'm trying to survive....I just.....give up."

I stormed out. I had to get to Twilight, she would know what to do.

As Derpy ran away, The changeling called in Dalek reinforcements, then went out a door, before getting word that a purple unicorn had tried sneaking in and was exterminated on sight. He smiled, and walked over to the Doctor, suspended in stone.

Getting to the library, I banged on the door as quickly and loudly as I could. "I'm coming, I'm coming!" came a voice from within. Soon after, the door opened, and there stood a bewildered Spike. "Derpy, what happened?" I quickly explained to him what happened and told him that I needed to see Twilight.

"I haven't seen her," said the dragon. "Not since she tried to sneak into that Dalek ship." This made my blood run cold. This probably meant that she was dead, now a pile of ashes on the floor of the Dalek ship. This wasn't good. "Spike, i need you to send a letter to Princess Celestia." Moments later, a distress letter was sent. Hopefully Celestia would arrive soon.

The changeling transformed into The Doctor, and ran out with screwdriver in hand. pressing a button, the TARDIS soon appeared.

Before long, Princess Celestia arrived. she was fast on her wings, being a goddess and all.

A look of relief came across my face. "Good, you're here. I think we're looking at a full-scale Dalek invasion here. Then the TARDIS appeared, and The Doctor stepped out. "Doctor!? It's been so long!"

I began to run to the changeling to hug him, but Celestia stopped me. "That isn't The Doctor," she said. "It's a changeling, possibly the one you mentioned in the letter." The alicorn princess cast a spell, and the 'Doctor' was reverted back to his true form. "You could never fool an alicorn," she said.

The newly revealed creature immediately facehoofed. "Well. Shit. I'm in trouble. I should possibly get the hay outta here then." I jumped into the blue box and started pressing buttons.

Celestia stepped forward. "Something tells me that you hardly know how to pilot that thing. And furthermore, now that you don't look like The Doctor, I doubt she'll even let you."

He  walked out of the blue box, smiling.

"You must be Celestia. The one responsible for murdering my kind"

"I would hardly call it murder if your entire race  is evil and bent on world domination, but sure, I suppose that you could put it that way."

"Evil? Domination? First off, you banished us to bucking death, we were pissed off. You Equestrians like to keep your goddamned love and not bucking share it. Now, I’m the last of my kind, trying to find willing breeders so that the changelings can return, and we could be at peace...I asked the Daleks to keep the doctor outta my mane, otherwise my plan to bring my kind back...would fail...it’s not an invasion, relax. Also found some purple unicorn, possibly your friend.....uh.......she was...er....exterminated."

Celestia looked taken aback by the news of her pupil’s death. But then she was over it.

"And so your plan was to rape this poor mare?" She gestured towards where I was standing before, but I  wasn't there.

"Well...what mare? The grey one? Maybe...look, when the changelings were alive, we didn’t ask our mares if they wanted to breed, But they liked it. I thought it was the same with you ponies....shows how much i know about you freaks."

Celestia considered this for a moment. Then, she said "I may seem cruel in your eyes, but in all truth I'm just doing what is best for my country. Maybe you see yourself as good too. But we have conflicting interests, and I do not see a peaceful solution." In that moment, The Doctor and I could be seen galloping in the distance. "You had better hope that he is in a forgiving mood."

He sighed, half hoping he would agree with him, half hoping he wouldn't kill him

The Doctor slowed to a stop in front of the changeling. He stared at you for a long moment. he could see the time behind  the Time Lord’s eyes, the weight of the universe on his shoulders, much like Celestia's eyes. Then he tackled the changeling, pinning him to the ground. He punched the creature in the face repeatedly, while yelling "HOW--DARE--YOU--HURT--MY--DERPY!!!"

The changeling blocked the punches as best as he could. "Oh shut up, Time Lord! You of all ponies should know how it feels to be the last of your kind!"

The Doctor was angry. He usually didn’t act this way, but the changeling had hurt me, so all bets were off.

"But that isn’t the way!!"

"Then what is?? No mare would willingly have sex with something like me. The future of the changelings....is screwed..." He started to, for the first time in years, cry.

The Doctor lightened up on his punches, then stopped. Getting up, he said "I may have a solution for you that would never work for me." The changeling looked hopeful. ".R-Really?"

"Yes, It's simple really. Actually not simple at all. You see, the DNA of changelings is very easy to manipulate, as a result of their shape-shifting powers. And so, it wouldn't be out of the question to create another changeling, a female one, from your DNA."

"Yes...but there's the problem. With Chrysalis, every changeling was from her DNA, and they turned out....evil drones. So i thought that mixing pony DNA from your marefriend Whooves and my DNA wouldn’t make the offspring brainless drones, but instead free-thinking changelings.."

"The way that i could do it would make a free-thinking one working you want, not just a cheap knock-off. You see, I want to, in laymans terms, take half of your soul, and put it in a new body, not just make a mindless drone from your blood. The only drawback is that in doing this, you, your clone, and basically every changeling after that, would lose the ability that makes them inherently different... That is, the ability to shape-shift."

The changeling sighed. "No.....forget that idea..." He walked off, sighing. "Besides...whoever heard of a changeling who couldn’t....change form?"

It's either that, or total extinction. Think about it." The conversation was cut short by the sight of a Dalek ship in the skies. “What did you do???”

He turned back to face the Doctor, smiling sheepishly. "I've asked the Daleks to keep you out of my mane.....I thought you were gonna be a pain in the plot."

"Well now they're going to murder the entirety of Equestria, possibly the world!" The Doctor quickly wove some of his regenerative aura into the air, Then Celestia used it to power up her healing spell. Before long, I was healed, wings and all. "Cmon," He said to me, gesturing to the TARDIS. I

went in, and Celestia followed suit. "You're coming with me," he said as he dragged you in with him.  "Gah!"

Minutes later, the TARDIS appeared in the heart of the Dalek ship, just out of sight. "Okay, here's the plan. You call off the attack," He said, pointing towards you. "We will stay here where its safe. If that doesn't work, we'll have to go with plan B." "What's plan B?" I asked. "I don't know yet," he said sheepishly. "I have linked us telepathically, so you can speak to us while you are out," said the princess. "Now go," The Doctor said as he pushed the creature out the doors.

The changeling smirked, walked to the bridge, and told the Daleks to retreat. He was shot, yet surprisingly, He was dying slowly. He faintly saw me running towards him. "Oh no. I knew that wouldn't work. What was he thinking?" I put him on my back, and sped off to the TARDIS.

Weakly, the changeling opened my eyes and noticed that the grey mare known as Whooves had brought me back to the TARDIS. dazed, he tried to get up

The Doctor frowned. "Yeah, that was a stupid idea. But it gave me another one. The fact that you aren't a pile of of ashes right now is astounding! That means that changelings must be resistant to the Dalek's death rays."

The creature sighed. "Doctor, perhaps now i should give you your...uh....whatever the feck its called...the...i think davros called it a sonic......oh wait, i gave that to the Daleks two days ago."

"Oh, that's bad. the Daleks likely recreated it, turned it into a weapon..." He was silent, lost in thought for a moment. "Wait! Do you have one of these devices?"

"I did....i think i shoved it up Whooves' plot....i may have forgot to take it out..." He weakly smiled.

Blushing, I pulled it out, a disgusted look on my face. "Eww."

After a moment, it was washed off. "Okay" said The Doctor. "We're going to fight fire with fire."

"How so, you idiot!? Those don’t work on Dalek shells, I tried. and i’m slowly dying....but of course, you'd rather see my race extinct....."

"I never said that. Celestia however...." The princess in question rolled her eyes. "It doesn't work on them because it isn't reverse engineered to do so. Derpy, do you still have that spare sonic i gave you?" Nodding, I grabbed it out of my saddlebag of handed it to him. Taking it, he smiled. "You see, it's simply a matter of reversing the polarity of the neutron flow!" He did a thing with his sonic to the Dalek-sonic, and that apparently did what he wanted to do.

Annoyed that they apparently just wanted to save their kind, without caring for him, the changeling weakly dragged myself out of the box, pissed. "Ugh....buck you guys..."

"For bucks sake, can you bring him back in here Celestia?" The princess did as she was told, even though she was royalty and he was just a mad pony in a box. "I'm not giving up on you," he said to the changeling. "You're going to live. In fact, I you aren't even that badly hurt. like I said, you seem to be resistant to their death rays."

He used the Dalek-sonic on the changeling, and he was healed. "Just as I thought. this can now reverse the effects of the death ray if it doesn't kill you instantly. Now it should also have a deadly effect on the Daleks."

The creature grinned. Maybe it wasn’t time to tell him the important thing...or maybe it was. "Doctor...can i speak to you...privately?" I gave the princess a glare.

The princess scoffed, and walked into the other room. "What is it?"

"Well...when I was....forcefully breeding with Whooves....I noticed that sometimes, she actually, genuinely got pleasure from it....uhh....um....how do I say this...." he sort of stared at my flanks.

"That's because before that, she had never slept with a changeling before, of course she got excited sometimes And if you're worried that she might become unfaithful, don't be! We aren't exactly exclusive. We ARE together, but she sleeps around, and i let her." He looked at the mare in question, who wasn't paying attention, as she was preoccupied with a particularly scrumptious looking muffin. "She really is a different kind of mare."

"I was going to ask if you would let me breed the grey one, but, seeing as i screwed things up, i doubt that. She could be the only hope for my kind, doctor."

"I'm not sure if she would be up for that. You would want to bring that up with her, and this time be a gentlecolt about it."

"There's another problem.....i...don't know how to be a...a....gentlecolt."

The Doctor looked annoyed. "We can talk about this later. we have more pressing issues."

"Yes...wait. I know what to do. Stay here, Time Lord." the changeling rushed out of the box, to the storage room, hopped into a spare dalek shell, and drove it and three other empty shells to the box. Poking his head out, he yelled. "Doctor! Grey one! Freaky white pegacorn! Get the hay out of there and into the shells!" The Doctor and I came out, followed by a Scowling Celestia. they got in the shells.

"I retrofitted the binary couplings, that way we can easily control them. Doctor, if you'll just insert your sonic into the port labeled weaponry system, then we'll all have dalek destroying weaponry...also....whooves....I’m sorry we didn’t meet on a clean slate, as they say in...ah, buck it. allons-y!”

The Doctor was flustered. "H-Hey, that's my line!" but he did as he was asked, jumping into the first shell. I looked at the creature, smiling. "Oh, that's all right. I had fun!" I bounced into the second shell. Celestia walked up, growling at the changeling. “After this is over, I don't want to see hide nor hoof of you ever again." She climbed into the third shell.

The changeling grinned. "Oh, shut the buck up, Celestia. All of you. Activate your communication radio arrays, and listen up. You three go towards the bridge, i'll shut off the machine that makes the sonic weaponry. GET A MOVE ON!"

Celestia and I hesitated. Then the Doctor yelled, "You heard him! Lets go!" We  turned to leave but I stopped. "Wait, what's your name?"

"My name isn’t important, Whooves, only your species' EXISTENCE. but, my name is Crystallion.

"Ok!" and with that, we all left.

Crystallion made his way towards the machine, and destroyed it, destroying my shell's life support in the process. Unwilling to die in the shell, he popped out, and, weaponless, made his way to the bridge, passing the three pony-driven shells "I hope you know what you're doing," The Doctor said, worried.

Crystallion grinned. "Nope. I don’t." Then he ran to the bridge and started shooting Daleks left, right and center. He locked course for a black hole, and grinned. "Doctor, get Whooves and the princess out of the ship. NOW. I have turned on the self-destruct sequence. Save yourselves."

"NO! You're coming with us!" I jumped out of the shell. Get on my back!"

I growled at Whooves. "I'm sure that Celestia would love having me sacrifice myself for you guys.

Now get the buck out of here before i go batshit crazy!!”

"Oh, shut up." This voice came from Celestia herself. Just get on her back, you nitwit."

He mocked Celestia for a bit. "Oh, shut up..." I then got on my back

I sped off, not nearly as fast as Rainbow Dash, but still impressive. The others followed suit, and soon all were in the TARDIS. Moments later, we all watched as the Dalek ship was sucked into a black hole.

Crystallion gave Celestia a smirk. "Not bad for a filthy no good changeling, eh, you royal prick?"

"I guess so. You were prepared to die to save all of Equestria, and for that I am thankful. I take back what i said earlier. You are welcome in Equestria." The princess looked apologetic. "All in a days work," said The Doctor chuckling.

Later, after the princess was back in Canterlot, The Doctor, Crystallion  and I sat in the TARDIS. "I think theres something that Crystallion here wanted to ask you," he said to me. I gave the changeling an inquisitive look. "What is it?"

"I...er......wanted to ask if you were...uh.....willing to help me bring my species back through...uh.....breeding with me....."

"I would be glad to! but be gentler this time, ok?"

"Okay."

The End
