A Fabulous Mix Up

Story by Mehlahphuse on SoFurry

It has been a while since I have uploaded here. So many projects I had started and either dumped or simply left unfinished. This is my first attempt to get myself writing again. Doing something I used to love before life started pounding on me. I'll admit it will likely come off as awkward to read in places. I'm very rusty. Very out of practice. And it has also been hard to visualize my story (I try to form a mental picture and put words to it) with real life distracting me constantly. But I'll keep trying to do this. And finish things I still owe. And return to something I regret leaving for so long.

Anyways to sum up this story my self-insert (I'm not gonna even pretend I don't self insert into these) gets a hold of a mixture that is supposed to turn him into the anthro gal of one of his many various fantasies. However a slight mix-up in the order causes things to go awry.

By the way if you are confused as to why I use male pronouns (at first) while my self insert is trans-female its because I have yet to figure out how to convey a shift in physical sex and have the real gender pronouns come off naturally. It is something I need to work on without confusing the reader.


Stephen stood in his bedroom holding a vial in his hand, lightly swirling the concoction that reminded him a bit like cotton candy in terms of colours. A mix of purple and blue swirling together within the vial. It was his recent purchase from Ditto Pharmaceuticals, a company specializing in distributing serums and pills made for transforming humans into pokemon and poke-human hybrids. From what he knew they somehow used dittos, or rather their unstable genes, to allow humans to transform into the pokemon whose genes were used as a primer. Basically a successful attempt to replicate ditto's transform ability (excluding the failed attempts but no one really talks about those). Hence the name of the company. And that brings everything back to the vial in Stephen's hands. A vial that will turn him into an anthro rapidash. More specifically a female galarian one. At least for a few days. It took him a lot of paperwork and a blood sample for a reversing formula should something go wrong but he finally had the means to experience what many others have been. Who knows, maybe if he enjoyed the change he might fill out more forms to take things in a more long term direction.

Who was he kidding. Course he would take the more permanent plunge. At least, once he was sure it was safe enough to. He looked over his self. Pale skin. Long lanky arms. A bit of ponch in his belly covered by a plain white t-shirt. Long skinny legs covered by jeans slightly torn at the ankles. Wasn't really much to look at in terms of physique. He brushed his long very dark brown hair out of eyesight. He could go for a trim but at the same time he longed for longer hair. He adjusted his round rimmed glasses a bit on his face, blue eyes returning to gaze at the vial in his hand. The transmutative drink that will let him not only leave his humanity behind for a while but also experience what he always felt deep down. To finally be something physically the ignorant would say was only in his head.

Today he was about to become a woman.

"Well, guess this is it. My first step into life as a pokemon gal. Bottoms up I guess."

He quickly popped the cork and chugged down the potion. Unsurprisingly it tasted just how it looked. He was glad they flavored these things. Course now was the question of how long it would take before the changes started. The instructions said it was fast acting but that could mean anything from instant to 5 minutes from now. He was about to pull out the instructions again just to double check if he missed anything when he started to feel a pressure on his face. It felt like nasal congestion at first but as the pressure built he notice his nose was starting to look bigger, taking up more and more of his peripheral vision while slowly shifting his glasses.

"Huh, that was fast." Stephen said to himself as he rubbed his nose. Felt weird but oddly nice feeling it grow bigger and rounder. The feeling extended to his jaws as well, his entire face contorting and slowly stretching. Before his glasses fell off his transforming face he decided it best to remove his glasses. Just in time too as he felt his ears begin to stretch and change positions on his head which was a truly queer feeling but still not unpleasent. The changes didn't seem restricted to his head however as he was starting to feel a pressure in his pants. Realizing he should have removed his clothes before chugging a liquid ment to change his form he quickly moved to remove his belt and slide down his pants. Was a good thing too as he felt the beginnings of a tail forming and his backside growing more plump. The last thing he needed was to feel the pain of having a tail trapped in ill fitting pants. He slipped his underwear off, blushing as he noticed he was getting aroused by these changes.

"Better ditch this too." Stephen said as he started to remove his shirt. He shivered a little as he felt a tingle across his entire body. A tingle that turned into an itch he started scratching. As he scratched he noticed the hairs on his body turning white with more hair sprouting. No, not hair. Fur! He was sprouting fur. Very soft fur too as he ran his hand over the thicker patches. Soft and luxurious. Just like a rapidash. It felt so good to stroke as well as have stroked that he fell into a prolonged self petting session, rubbing all over his body. His hands stopped over his slightly flabby pecs and noticed they were a little swollen. He smiled as he wondered how big his new breasts were going to be though as he looked at the swelling flesh he found it a big odd how they sagged. But then again he had to remember real boobs weren't like how they often were in artist renditions. Still there was a small nagging in the back of his mind that something was a bit off.

He took his mind off his forming tits to focus on something else new he was gaining. Rubbing his forehead he felt the beginnings of a horn beginning to grow. Growing out roughly 20cm tall. Hard to tell without a ruler or measuring tape. Though it was odd it stopped there. He could have sworn Rapidash horns were longer, galar or otherwise. Maybe it was a convenience thing the drug makers manufactured in? It would be more difficult putting on clothes with a horn roughly 1 meter tall. The horn wasn't the only thing that felt off as when he ran his hands through his hair. It was growing longer as expected. Rapidash did have very long manes. But it felt like it was forming into one large clump rather than long silky strands that he was expecting. He quickly looked back at the tail which was still growing and sprouting hairs. Sure enough it looked like he had cotton candy growing out of his spine rather than the majestic tail he knew from the pictures he admired. He decided to quickly check the vial and packaging just to be sure he didn't make a mistake in his order. He grabbed the vial and box. Fortunately the change appeared to be fixing his eyesight as he could read the labels of each just fine without his glasses.

The vial itself oddly wasn't labeled but the box had humanoid galar rapidash written on its label. There was even a picture of a clothed anthro galar rapidash on the box. What he should be becoming. Yet his tail, mane, and purple tufts of fur now sprouting from both his wrists and ankles were telling a different story. So if he wasn't becoming a rapidash there was only one alternative he could think of. He was becoming the unevolved form of rapidash. He was becoming a galar ponyta. Certainly not what he had ordered and rather a bit of an annoyance. While he would have words with the company later once he found the proper number to call it wasn't exactly a bad thing. Ponyta was still pretty cute and the galar version doubly so. Still he was hoping to become something more queenly though still youthful in appearance rather than a princess. He was just glad age wasn't affected by the process.

The loss of feeling in his fingers brought his focus back to his changing body. His hands started to spasm and warp, fingers sticking together and unable to come apart no matter how hard he tried to move them. He dropped both the vial and the box as his morphing hands could not hold onto them anymore. He watched in shock as they squished together into one hardening mass. His hands were turning into hooves! So not only was he becoming the wrong species but his body was going full pokemon too? Well this was just great! Now he won't even be able to even make an angry call to Ditto Pharmaceuticals. Or do anything that required human hands. How in the name of Arceus could they have gotten his order completely wrong?

And odd squirming feeling drew his attention back to his chest. In both shock and awe he watched as the breasts he was growing start moving down his body which was starting to pack a bit more animalistic bulk. Wait... Those weren't breasts. Those were udders. Equine udders to be more precise. At least he thought that was the proper term. Wasn't exactly in a spot to look up online the proper terminology for feral horse tits. Especially when his feet felt like they were cramping up and he was losing his balance. Quickly he landed forehoof first against his bed before he fell backwards. His arms shifted not too long after landing, locking him in a quadrupedal stance. Both his arms and legs began shifting in size while he felt his toes scrunch up just like his lost fingers. As he watched his feet meet the same fate as his hands he didn't notice he was shrinking, losing a couple feet in height. He also couldn't see his eyes growing bigger, the whites turning a full dark blue while his pupils turned white. Soon his feet were hooves just like his hands, now standing on four beastial legs instead of two humanoid ones. His transformation was essentially complete. Well with one thing still remaining.

"Well, guess this ride is almost done." Stephen said as he looked down between his legs, still seeing his out of place human genitals. "I just hope they didn't screw up heeeeeeeeeaaahhh!"

He cried out as his shaft suddenly sprung to life and started throbbing hard. It felt like an invisible hand was stroking him off and it was stroking hard. The feeling was so sudden and powerful that he ejaculated all over his bedroom carpet. His eyes rolled back as he couldn't stop climaxing. He should have been worried that he was unloading like a coke bottle shaken after an earthquake if he was able to even form a thought through all that intense pleasure. He couldn't even process that, as his semen coated the floor, his dick was shrinking and balls were pushing into his equine body. The skin of his sack began sinking Into his body leaving behind a fleshy gash, his balls traveling further inside as organs shifted around. He huffed and moaned as his last male climax started to slow as the last of his sperm left him. His human cock was barely visible as new folds formed and his horse rump shifted a bit more. His hips widened painlessly and things shifted in position behind him to better fit his new body shape. The new female folds grew thicker and flesh darkened, looking more like proper mare genitals. With one more cry that sounded more like a whinny he climaxed one more time. Not as a male but as a fully fledged female. Panting after that climactic finish Stephen collapsed against the edge of her bed, panting heavily.

"Holy shit... *huff* I read a change in gender could come off strong but that warning certainly didn't prepare me for that!" The now ponyta exclaimed to herself, just now noticing the change in her voice. She sounded so girly it reminded her of animations made for young girls. "Oh mew, I fricken sound like a cartoon character."

She frowned a bit and unsteadily got onto the floor on all four hooves. Still wobbly from the end of her transformation and unused to talking on all fours, she took a few practice steps, nearly falling into her face a couple times but eventually managing to get the hang of walking.

"Alright. I think I might have walking down." She suddenly stopped when she heard a soft squish and looked down to see that she just stepped in the remains of her masculinity. "Oh eww eww eww! Ack! How am I even gonna clean all that up like this! Argh!"

She cried at her ceiling in frustration. Frustration turned into surprise when stuff around her flung around her. She was about to ask out loud what just happened when she stopped to think. She then remembered she was now both a fairy type and a psychic type pokemon. So it stands to reason she can move things with her mind. So if she concentrated she could lift and move anything. To test this, she tried it on her desk chair. She stared at it and pictured it lifting off the ground. Her horn began to glow and sure enough her chair lifted into the air with ease. She was actually surprised how easy this was. It was like she was born with this ability. With this revelation she started to clean up all the stuff she accidentally tossed around in her hissy fit with her new powers and even got around to cleaning the mess in her carpet. Sadly it still left a stain. She'll have to get a steam cleaner or something to fully remove that sign of shame.

She jumped up in surprise when she heard the phone ring. On impulse she galloped out of the room and towards the phone in the living room area. Course it wasn't exactly an easy journey despite the short distance as hooves don't go well on uncarpeted hardwood floors but she managed to make it to the phone in time with just a slight bruise to her flank. Without even thinking she telekinetically picked up the phone.

"Hello?" She mentally grumbled at the reminder of how girly her voice now sounded.

"Hello. This is Diane calling for Ditto Pharmaceuticals. Is Mr. Stephen Geisbreche there?"

"Speaking... and it is her now." She couldn't believe they were calling her. Just as she was thinking about calling them to complain about the messed up order. Course that brings up the question of why they were calling her.

"Oh. Well we're calling because it has come to our attention that there was a mix up with your order. While it isn't company policy to reveal the cause we did find in our records that you were sent the full form, semi-permanent, female Galar ponyta formula instead of the human form, 4 day duration, female Galar rapidash formula. I apologize for any distress this may be causing you at this time."

Stephen snorted and glared angrily at the phone but did her best to keep a polite composiour. This was just a help desk employee and not the ones actually responsible for the mix up. "Yes, I am distressed. I mean if I hadn't learned about my psychic abilities as surprisingly quickly as I did, let alone had the power to move things with my mind at all, we probably wouldn't be talking right now as I'd be unable to pick up the phone. Also did you say semi-permanent? Please tell me you have a reverse formula made. That's why you took that DNA sample, right? To have one made for me in case something went wrong. In fact..." Stephen stopped to think for a sec and just realized there was only one vial in the package. "You didn't even send me the reverse formula. What gives?"

"Umm... please hold." There was a very concerningly long period of hearing faint talking in the background before Diane returned. "So I just talked with some folks from the lab and I have some good news and bad news. I'm going to do my best to explain it but from what they told me they couldn't make a reverse formula from your DNA. The fact you were sent your package in the first place, even if it was the proper order, violates our company safety ru-."

"WHAT DO YOU MEAN YOU CAN'T MAKE A REVERSE FORMULA? HOW THE HECK AM I SUPPOSED TO CHANGE BACK THEN? I CAN'T LIVE LIKE THIS!?" Stephen shouted into the phone, all composiour lost by that nugget of information. How incompetant can these people be? She was all for becoming a humanoid pokemon lady but to be trapped like this? She had no plans to work around a quadrupedal body like this. How was she supposed to function? Or avoid being confused as a regular pokemon and ending up trapped in some kids pokeball? She was starting to hyperventilate cause this was just too much.

"Please sir.. err... ma'am.. umm.. Just please let me finish explaining. The doctors told me the reason why is because you have blood that apparently works far too tell with our formula. How they explained it to me is your genetics have a 95% bonding rate. Meaning that they bond really well with the ditto genes we use in our formulas. So well that if the formula you drank didn't have another pokemon's genetics as a primer you'd be a ditto right now instead of the ponyta you are now. They even told me that any higher and even with the primer you'd get... really? That is the term you are using? Ok, fine! ...dittofied."

Stephen sat down on her hindquarters and let this all sink in. "So you're telling me that if things were slightly different this mistake could have left me as a ditto for the rest of my life?"

"Yes but fortunately this is not the case. Unfortunately this does mean they have been unsuccessful in forming a reverse formula as each attempt resulted your genes completely being overwritten in every test sample. However there is some partial good news. It isn't a solution but we can make you a human form ponyta or any pokemon of your choosing. We do ask we have someone bring you here to our labs or at the very least allow one of our experts into your home so we may administer the new formula so if anything unexpected happens we can respond accordingly. If you do not want this we can offer you other compensation within reason. So which do you want?"

Stephen looked down and thought about this for a sec. She was considering the pokemon life anyways. But she wasn't exactly prepared to stay like this for the rest of her life. She mulled it over in her head for a bit before finally giving her response. "Alright. Send someone over. Though before you do I have some extra conditions I wish to talk over with you first."


Cheers and applause came from the audience as the show host came up on stage. She was a caucasian woman in her mid thirties with short red hair, blue eyes covered by squared black rimmed glasses, and wearing a velvet red suit with blank pants. She waved to her adoring audience and the cameras pointed at her before taking a seat behind her onstage desk, a city backdrop behind her.

"Thank you! Thank you!" She said as her audience calmed down. "Welcome to Unova Tonight with me, your lovely host Joanne. Once again we got some amazing guests lined up tonight. And our first might just have the most interesting tale to tell. She is one of the stars of the Live Action remake of My Little Ponyta and model for Meloetta Fashion magazine. Please give a warm round of applause for Meleny Stardust!"

The audience cheered again as a well dressed galar ponyta pokemorph stepped onto the stage and waved back. She stood at 5'3 and had the appearance of a young lady whose teenage development treated her rather well. Her fur was coloured a lovely shade of violet, granted not her natural fur colour, and her mane and tail were dyed a dark purple with a mix of strawberry pink. She was wearing a sparkling red dress with matching red hoof heels. It wasn't one of the latest designs but it was her favorite. She did feel a little embarrassed as they had the theme song to her show playing as her entrance music but she didn't let it show as she strode forwards and took her seat next to the host's desk. She was certainly grateful once the music died down and the audience calmed down again.

"Thank you, Meleny, for taking the time to come onto the show. I heard you were in town for charity visits at the Unova Kids Hospital."

Meleny smiled and turned to Joanne. "Why yes. It is for the Jirachi Wish Foundation. Brightening the days of sick kids with my costars, Cindy Dewmane and Wanda Firehoof. Sadly the other girls couldn't come. Jackie had a family emergency and Lisa... well... she'll probably kill me for this but she is dealing with some girl troubles, if you get what I mean." Meleny chuckled a little, getting a little bit of laughter from the audience. "But yeah, I am glad to be here in Unova helping kids smile and also raising money for the foundation."

"That's fabulous to hear, hun. Not everyday people get to see their favorite pony actor for real. Though I do have to ask about this rumor that has been going around that you weren't always the Galar princess we Have here on stage. And I am not referring to your acting career."

Meleny knew this question was going to come up eventually and yet she still felt unprepared to give the answer. Still she wasn't gonna get anywhere by keeping silent about it. Best to try to be nonchalant about it. "Well if you must know I used to be human. And this also might blow your mind but I used to be a guy too."

"Really?" It was hard to tell if Joanne was legitimately surprised or just playing it off for the audience. "And how did that happen? How do you go from being a guy to...how do the kids say it? The best ponyta?"

Melena smiled and gave a slight snort. "Well truth be told it was an accident that ended turning out better than expected. You heard of Ditto Pharmaceuticals, right?"

"Yes! They were the guys that started the whole humans becoming pokemon fad right? Didn't they go out of business recently?"

"Right. And yes, though from what I heard many of the scientists there are working for Palkia Labs now. But I digress. So yeah, I had heard good things about the company at the time and it all sounded like a dream come true. I should also say that I played off the guy part a little strong. I actually used to be a trans girl. Though now I don't think I need the trans label anymore considering my current beautiful physique." Melene said as she ran her hand through her mane. "Anyways I had originally ordered the humanoid galar rapidash formula but low and behold there was a mix up and I actually ended up a fully quadrupedal ponyta. Just like how I am on the show."

"Wait so the stuff you took made you a full on ponyta? But how are you a pokemorph now?"

"Well the company actually got back to me on that as they found out someone had been sleeping on the job and shipped me the wrong stuff. And it kind of turned out that I had a rare gene that made it impossible for them to change me back. But after working some things they were able to change me into the humanoid form you see today. Though I also had them compensate me a lot for what they did to me. Mistake or not they did owe me for leaving me stuck in an unfamiliar body. New name, new ID. Stuff like that plus a settlement to keep me from suing."

"Right, but in the show you are a regular ponyta. Is that all CGI trickery or how do they do that?"

"Ah! Well that is where my weird DNA comes into play, Joanne. Turns out that after giving me that second dose to give me back my hands and allow me to walk on two legs again I had gained a lesser form of ditto's transform ability. So I can shift from biped to quad and back again at will. It's actually kind of freeing to just slip off civilization for a bit and go full pokemon for a while out in the open fields. Also I will admit I have had fun giving kids ponyta rides at parties."

"Wait! So you can change forms at will? Can you show us right now?" This time there was no denying the legitimacy of Joanne's expression. The curiosity and wonder was clear as day for all to see.

"Sadly my agent and several others told me I couldn't on stage. Mainly cause that would require me to take off my dress and last time I checked we weren't on JBO." This got some heartier laughs from the audience as well as a few hoots and hollers, making the ponyta blush a little. "Though I can show you after the show more privately." This got a lot more hoots and hollers from the crowd. "Not in that manner, you guys!" She frowned and crossed her arms in that cute fashion she had practised like an artform. The audience laughed loudly and even Joanne got a good laugh out of that line.

"Well, I certainly look forward to that.One more question before you have to go. Why Meleny Stardust? You said you changed your name but why that one?"

"Well that's actually a funny story. See it wasn't originally Meleny. Originally it was just Stephenie with no change to my family name. But after doing the live action show the role kind of grew on me. And the more kids started associating me with my character. So I got some stronger dyes for my hair. Had my fur fully colour treated rather than the typical fur paint we use on set. And after some paperwork voila! Meleny Stardust is now the real deal! Well, minus the whole princess of a magical pokemon world."

"Well whether on Webflix or in real life I think many would agree you certainly look the princess role. Anyway, we are out of time together. Thank you for coming onto the show and telling us all your humble origins."

"Well thank you, Joanne, for letting me on the show." Meleny smiled and got up, giving a little curtsey.

"Give a round of applause for Meleny everyone and don't go away! We'll be back after this commercial break!"

The crowd cheered and applauded as Meleny walked off stage. She actually felt good getting that truth off her chest. Her agent had his doubts about it but she felt it went off without a hitch. And while she remembered that past being a stressful time she had to admit if none of that happened she wouldn't be the rising star she was today. If she was sent back in time and given a chance to change anything back then she wouldn't change a thing at all. Not now, at least. She was even glad she turned down going rapidash like she originally planned. Though it was still possible for her to evolve if the scientists were correct about her transformation. For now she could enjoy her life and role as a pony princess from Evolutia.

Stephen Geisbreche was yesterday. Today there was Meleny Stardust!
