A displaced story starring the power ponies and a scientist named Derek from another franchise who became Naoto Shirogane A.K.A The detective prince. Co-Starring references to other franchises and the multiverse

Not so average scientist Derek Maximus is cosplaying as Naoto Shirogane from persona 4 (The animation), when he buys Naoto's pistol, cap and glasses from a strange merchant who was inside a tent. A tent which shows shining red eyes? After experiencing what could only be described as an Acid trip through a portal, he wakes up in a whole new world. And realises that the population are just ponies. And he's finally female after researching a serum to become one for ever since he started his job at Abbadon labs. (S)he also suspects that the merchant may have a crush on her. That's just a theory cause he keeps popping up and sometimes blushing. Yep. The merchant, force of chaos and the multiverse, F***ing blushing.

Main characters name is changed to Derek so that I can destroy the multiverse even more. You'll understand after the first Authors notes. Mwahahahahaha.

Sex tag is for calling things sexy and stuff. Nothin serious.

Story is not on hiatus anymore

Try not to swear too much in the comments. Thanx

Note: Needs a Beta Reader so I can post longer chapters without worrying about spelling mistakes.

Chapter 1 - Day ? - Location ? (Short)

Hello and welcome to me. Today has been one hell of a day and now my brain has been enhanced to be as smart as Naoto Shirogane and I'm standing in front of a strange pony corpse being eaten by a ghoul from Tokyo ghoul. Looks like a rule 63d one. Let me explain. My name is Derek Maximus, although now you should just call me Naoto. I was going to comicon after finally convincing Liam that I should get a break from work because working at Abbadon is fun but can get tiring. I finally got there after a three hour train ride and was pretty excited to go. I was cosplaying as Naoto Shirogane from persona 4.

When I got there, many people complimented my costume, saying things like "Wow, nice cosplay" or "that's amazing". One person even tried to get my number because they thought I was a girl (I was developing a gender change serum so they weren't really too far off). I forgot to bring the cosplay cap, glasses and pistol though. When I was looking around, I found a merchant who had everything I needed. He looked like a creepier version of the merchant from Dust : An Elysian Tail. I walked up and the merchant said "So a persona fan eh, I have just the things for you. And since your cosplay is so good, I'll give them away for half price."

"How much is half price then?" I replied. The merchant then stopped for a second as though he was thinking.

"Well, full price is £67.84." He said. I then said

"Is this a test of detective skill cause if it is then the answer is... Umm £33.92?"

"Good work!" He exclaimed loudly. I purchased the items and he said "By the way, I gave you fifteen shots of the pistol from infinite ammo a day and your phone will still be able to receive and send emails. Good luck." Everything suddenly went blurry and I fell to the ground. When I was getting up, I saw the scene I mentioned at the beggining. I decided to stay in the shadows just incase and decided to sleep where I was for the night. I felt so tired I could sleep for a month. So somehow, I did.

I slowly got up and stretched my limbs. I was in a purple room

Chapter 2 - Day 26 - Location Velvet Room / ? (Short)

"We would prefer it if you called it the velvet room" I heard.

Huh, who said that?Also, the velvet room? I thought only Yu and minato could go there

"Did you really forget about us?" The voice said again.

wait a second, that's Margaret.

"I'm glad you remember." Said Margaret calmly.

So what's this about, why can you hear my thoughts and why can't I speak here?

"Because most people are mute here except me and igor." She thought? I couldn't tell with that quote echoing unlike the others. Maybe I had developed telepathy and she was trying to keep that thought(?) a secret

Where is Igor anyway?

"He's not in here right now. Do you realise that you have been asleep for 26 days."

Wait, WHAT!? "Don't worry, nopony noticed you" Oh good. The only bad thing now is that I'm in a coma. Also, nopony?

"Who said that. Your half awake now." She replied, ignoring the nopony comment

Okay. In that case, can you wake me up now?

"Nope, just wanted to tell you that you own the wild card now but you still have to accept your shadow."

Are you sure I'm not just drugged up

"100% positive." She said with a trolling smirk. I can't trust a smirk like that but I have to.

Well in that case, when can I leave?

"In a few minutes."

Why? "Because you have to encounter this new species somehow."

So your gonna wake me up in front of a Horse

"They prefer being called ponies."

Whatever. Wait, I haven't spoke since the transformation. I may sound like Naoto. AND FINALLY BECOME A GIRL!!! Gender swap serum can go burn now. I just wish I still had the genetic infusion chamber. Wait, isn't Naoto pretty much... I trailed off, even though that should be impossible for my thoughts to do.

"Maybe you will still have it. Also chances are, you're a like Naoto now, Flat and short haired. Well, goodbye for now."

No, not flat and short. Noooooooo!! Also, wait, I have morequestionsssss

"I hope you enjoy this new world. Also, get you're priorities straight. Big boobs and long hair aren't everything."

When I awoke, I was tied up in front of a strange Pony woman. Mare? Anyway, she tied me up with her hair (WTF) and exclaimed "Hm, another Human. I am the Mane-iac, but you will soon call me master. The last one of your kind may have beat me but with my mind control hair spray, this one shall help me defeat the power po-" I kicked the 'Mane-iac' in the face and she dropped me. "Another resilient one, no matter. I shall still control i-" I shot her in the leg with my pistol.

"I can hear you, you know. And you shouldn't monologue around me. It's bad for your health."

Chapter 4 - Day 26 - Location Maretropolis

"Yes, yes it did." I heard, so I swivelled my head towards the voice. He looked like a creepier version of th- HOLY HELL IT WAS THE MERCHANT.

"So, why are you here?" I asked him. "Are you here to mess with my life some more?"

"No, I came to tell you that you are one of the most chaotic displaced I've ever sent to an equestria ever."

"Yeah, and?" I asked curiously

"I gave you a second form which you would have received if I didn't displace you. In fact I gave you all of them." He said. "Just say the name of the form from this piece of paper and you turn into it. They're written how you would write it." He continued. He then handed me the piece of paper so I read everything on the sheet.

"Sexy chick, flat chick with short hair, slime chick, snake chick, cat chick and furry." I would have recieved those in regular life? Awesome. Also, furry? I realised that I was still in the 'furry' form and noticed I was a green furred cat person. "So that's why my body felt weird earlier when I was saying those. So to change back I just say Naoto?" I then changed back.

"I'll talk to you later anyways, also check your email. Liam may send something interesting."  He said in a familiar voice.

Wait, email? Liam? That voice? Yael? "Come back here Yael, you... Um... You Scrub. There we go, an insult." I yelled

"I'm not Yael, I just like trolling you and your friends." He said in a gravelly voice. Then he shifted to look like the merchant from the resident evil games.

"Don't you dare F with Liam!!" I yelled, but he simply moved his hand down and I suddenly fell face first into the floor. He opened a black portal and dissapeared into it. "So I guess I should try out my new forms." I said weakly after wasting three minutes trying to pull myself out of the dirt. So I yelled "Slime girl mode!!!" it was awesome and totally dramatic, just ask the anynobody here.

When I yelled, my arm looked like it was melting into blue goo, and then I was a blue puddle. I focused on forming my human form and ended up looking like a woman with long hair and Huge boobs. Except I was a blue slime. Not a problem. Nope. Not at all. I then yelled "Sexy Chick Mode!!!" I was the same as the last form except for a blue dress, a bra and actual hair. And it was long and green. Also skin. Can't forget skin. Still, better keep to the original form so as not to confuse anyone. And I should stop shouting. So I said "Naoto." And transformed.

I missed my busty form already, but I had to stay in character here.

"Gee, the power ponies helped stop another crime today. That's amazing" I heard from outside the alleyway. They have superheroes. Really? Even I'm not that childish, and I tried to make a serum to become a woman who I can now become anyway. I think using the slime form takes a lot of energy but the sexy chick one worked fine without energy costage. Hey wait a second, the merchant said I could email and that something happened. I need to check on Liam.

,

I opened up my flip phone. It said it was at infinite charge? The charge bar became a green infinity symbol. So, it also had six-hundred and ninety-two bars of wifi. WTF? So I checked my emails and had one from Liam that said that they tried the gender swap serum, and it smashed against the wall because when balancing the vial, Yael went scrub mode. So they're all female, except for the one woman who became male. Wow. They got to partake in my dream and I wasn't there. Also, Liam now goes by the name Lynn, she accidentally gave Yael my just-in-case-it-works breast enhancement serum and Dan isn't coping well. She sent me a picture of herself and damn is she hot.

I sent Lynn an email about what happened and showed her a sneakily taken picture of what the street looked like. She believed me, surprisingly. I sent her a picture of all of my forms, in order of the sheet of paper. She described them as in order " Sexy, Cute, freaky but cool and sexy, Really useless (I replied the fact that I can constrict things.), adorable and sexy, and strange."

I think I have extra abilities compared to other displaced because of my new forms but that just made them better. I called them displaced because that's what merchant guy called them and cause he acted like there were more than one. Suddenly, I was nailed in the head by a book. It set on fire and exploded. What the hell was that I wondered. Maybe it was just an attack attempt or something. Oh well, it's gone now. Also, I had detective vision now, after thinking about it being an elaborate attack plan. I looked at the crater of ashes. It didn't look safe. I looked carefully and discovered that it had fallen from a tree and been cursed to be a grenade. That's seriously what the detective vision told me, and I'm not arguing with batman physics.

Chapter 3 - Day 26 - Location: Maretropolis?

"Now answer a few questions for me. The first: Where the hell am I?!" I shouted.

"Your in my secret base in maretropolis." The pony 'supervillain' exclaimed

"So your secret base is an alleyway. Or did you get kicked out of the first for being an idiot."  I said.

"If you must know, my old base was shut down by one of your kind."

"Well then, you're used to what's about to happen." I replied. "Now, do you notice the pain on your leg."The minute I said that she realised it and screamed in pain.

"I can do that to you again. In fact, 14 more times today." Then the mare ran off and I sat down. "YOU BETTER RUN!!!!" I shouted. Then I realised that I sounded exactly like Naoto.

"It looks like my dream of being a girl has come true." I said happily. I hopped back up and started skipping around in a circle. Then thought Now to be extremely dramatic and picked up a random card with a magnifying glass picture on it. I wonder why that was there I thought before getting a sudden urge to proclaim who I am. So I said I am Naoto Shirogane. The detective, the persona user and the friend of good. If you are good and seek assistance or a friendly chatthen crush this card in your hand. If you are evil then let's just hope you like bullets in your brain.. I then accidentally dropped the card and it was swallowed by a portal. wut?

"Did that seriously just happen?" I questioned the air. And a voice answered

"Yes. Yes it did"
