I do not own one piece

Fair Warning: At one point in the chapter is gets dark. I've marked it so if you wish to avoid it you may, it does retain to some of Katsu's past. I do try not to go into detail but as to avoid any kind of trigger I have placed a warning for ya'll.

...........................................

 "There, there, Captain." I mumbled, patting Luffy's back as he crumbled down on the ground crying about the disgusting legs he had on his back, which were no longer on his back. "I'm sure you'll..." I crinkled my nose in distaste, "fine another pair of legs."

The legs that had been on Luffy are no longer attached to my Captain. Instead it now has a detached head, which is apparently the owner of the legs. Though even now he's still missing parts of his body.

Meanwhile Franky, who is actually Nami, had whacked Nami, who is actually Sanji, as he... or she... was doing bad stuff to herself. Sanji, who is actually Chopper, is currently treating Nami's body.

Then of course there are the giant children. They're a thing too. A thing which I have no idea what to think of so far, but one of the smaller ones keeps staring at me and its weird.

"Ah, i wonder if this is a fever dream." I mumbled, "I've never been sick enough to have one, I wonder if I've finally fallen sick enough."

Did I take any drugs by accident?

Though I did contemplate the idea for a moment, I shook my head in the end. Even if I did, the likelihood of it actually working and causing me to trip this bad is very unlikely as my tolerance seems to be incredibly high.

Which would mean this is all real.

I wonder if Mamoru would believe this if I told him everything in detail?

"Shut your filthy traps!!" Franky raged, making the children surrounding him to run off.

I cleared my throat, standing up to walk towards the other crew mates who seem to be mixed up. My eyes trained to the cigarettes that were tossed on the ground before being placed in Nami's mouth. When Nami made the move to light the cigarette I blew out the flame.

"Don't do that." I mumbled, making them look at me with blinking eyes. "That's not your body, you shouldn't smoke in it."

"Katsu-chan!" Nami smiled then paled at the thought, "You're right..."

Crossing my arms over my chest I frowned and looked over the mixed up crew mates. "I think I have an idea, but go ahead and state who you are."

They nodded in agreement and Chopper stepped up first. "First, I'm Franky. Don't expect me to help you if you get hurt!"

How he managed to ruin Chopper's completely adorable face really confused me.

"And I'm Chopper!" Sanji popped up next, and I had to blink as he looked rather cheerful. Like Franky, the facial expression on Sanji looked like Chopper. "I will help you if you get hurt!"

"This is Nami." Franky pointed to himself, the tone deadpanned. "And I'd rather die than shoot a laser beam."

"But... the nipple lights..." I mumbled, puffing out my cheeks. "Lucky."

Nami opened her coat and immediately started groping her breasts. "And these babies-"

"Nope." I quickly stepped up and removed the hands before shutting the coat tightly and glaring at Nami, though it was truly Sanji I was glaring at.

"Sanji. Shame on you." I scolded, seeing Nami's freeze in shock. "You're inside Nami's body, therefore you need to be more cautious! Just because you're in her body doesn't mean she consents. You claim to be a gentleman, yet the first thing you do is grope Nami's body when she has no control over said body."

Nami's eyes widened as the realization hit her, and tears started to form in her eyes. "Oh no..."

"Yeah, stop that Rapey Cook." Zoro called out just as Sanji started to weep as he begged for forgiveness from the real Nami.

As Nami began to charge Sanji for his actions, I sighed and took out my sketchbook. Normally I loath the idea of tearing out papers, but this seems like a moment when they are needed.

"You don't seem too surprised." Zoro commented, looking down at me as I was drawing. I paused for a moment, glancing up at him before continuing to draw. Strange he would ask me that considering he doesn't look surprised at all.

"Yeah." I answered.

"I'm a bit surprised... Why aren't you?" He asked with a frown.

"You're all weird, this just seems like a strange day."

"The body switching?"

I  shrugged, "Fairly normal." It had to have been Law, but I don't know why he would do that to them.

"The leg guy?"

"Disgusting, and a bit weird."

"The random giant children?"

I paused at that, "I'm... worried about that one."

"Our crew mates being in different bodies, and a weird guy who has his body separated doesn't bother you as much. Yet, kids do?" Zoro asked, "I mean, I think its weird too, but our crew being in different bodies is weirder."

"Law did that." I answered, waving my hand when Zoro shot me a look of suspicion. "I don't know why, and I'm not sure about the gross leg guy. But the kids... this is an island that only allows marines here, so why the hell are there children here?"

My stomach dropped as the idea started to enter my head. They don't look cut up, so its likely they aren't undergoing the same experiments I went under, maybe they aren't being experimented on. Maybe they just happen to be kids of marines.

That doesn't make sense either.

................................

"We have here the samurai from Wano." Usopp explained, pointing at the sheet of paper he had me draw on for them. "The distress signal we originally picked up was sent to that boss croc-taur from one of his subordinates. In other words this whole state of affairs was started because our samurai friend here was slicing up the centaurs."

I nodded quietly then glanced at the Samurai who was really only a head and a set of legs currently. "I have more respect for you now, disgusting legs."

Robin giggled and patted my head to gain my attention. "Katsu, you may want to refrain from calling him that now that he isn't just legs."

I frowned and curled my lip at the memory of the legs stuck to Luffy's back. "Once my memory gets fucked up again and I forget them."

"I was only striking down those who stood in the way of my quest to rescue my missing son, Momonosuke!" I  paused as the Samurai spoke. "Simply observe how many children were locked in that laboratory! I know my Momonosuke must still be in there!"

A chill went down my spine and I felt goosebumps rise on my arms. They had been locked in a laboratory. My head turned to look towards the children, whom I knew for sure now were experiments.

"Yeah, we're not all the kids that were there." One of the smaller kids stated.

"We don't even know the names of the newer ones...."

"The problem is what happened after the S.O.S. Tell us about it." Zoro cut in, wanting to get straight to the point.

"It was that man! The one the others called a warlord of the sea, or some such nonsense..." The Samurai answered.

I grinned and laughed, "I told you it was totally him. Well at least for them, I wasn't completely sure about Disgusting Legs but it made sense."

"See, you shouldn't be trusting that doctor." Zoro shook his head, "He's a no good kind of doctor."

I felt a tug at the end of my sleeve, making me blink and look down. Surely enough it was the little kid that had been looking at me.

"You're Crimson Hurricane Katsu?"

My eyebrows pulled together and I nodded, "Yeah? Why?"

"Doctor Osamu has your picture on his desk." I felt as if someone had just pored ice water over me and my chest tightened. Why was it hard to breath? I wasn't controlling the air. "He said you were his best... How did you become the best? I want to be the best."

"Katsu?"

Who was that? Their voice was muffled.

My head was tingling and I felt a surge of crippling fear overcome my body. I couldn't catch my breath, and why was it getting incredibly hot?

"Chopper!"

Black overtook my vision and the chatter was replaced by something else. When I began to see again, I wasn't in the cave with me crew anymore.

-Contains Dark Themes Ahead-

Pain filled my body, and upon looking down I found I wasn't my current age anymore. Nor was I free. I was held down to a metal table, cool metal biting in on my wrists and ankles. My heart started to race as I felt tears fall down my face and soft cries escape me.

The door to the brightly lit room opened and a man walked inside, a blood stained lab coat still on him and a white mask covering most of his face from view.

"Dr. Osmau, her vitals have stabled." The doctor that laid eyes on me turned back to grab the clip board he was being handed. "She may very well be the first successful experiment."

My lip quivered as I brought my head up to look down at myself. No longer was I wearing the sundress Shanks had given me, instead I appeared to be in some kind of white loose clothing.

Everything ached.

Why did everything ache?

"Ah, it seems she's awake..." The voice sent a chill down my spine and made me glare with all my might at the marine that walked towards me. "I'll go ahead and inform you 0791, you should be grateful. Instead of being sent to Impel Down, or executed, you've been granted the privilege of being my test subject."

Immediately I began shaking my head, tugging my arms despite the metal digging in more and feeling warm liquid travel down my wrists. "N-No! Shanks is coming for me!"

Shanks won't let this guy hurt me. He should be here soon.

He has to be.

"Mmm, not likely." The doctor mumbled, pressing his fingers to my neck and pausing before humming contently. "I'm currently working on making the perfect weapon for the marines. Since you're young, you're perfect. All of the older test subjects die immediately after the first test. Yet, you've not only made it to the next day, but you seem to be taking perfectly to it."

He paused to write some notes. "Once that Pirate learns you've become a weapon for the marines, they'll all abandon you."

"You're lying!" I shrieked, my eyes widening as more tears filled my eyes. Mom said Shanks would never leave any of us, no matter what.

He wouldn't abandon me. He wouldn't abandon Sato or Makoto either.

He'll save me, and them. All of us.

Then we'll be okay.

But... I don't feel okay right now.

"You'll be an enemy to them, 0791." He rolled his eyes, turning around and walking behind me to mess with something. I could feel incredible heat emitting from whatever it was.

"Now then, considering you're the first to actually live past the first test, and you're already on the way to recovery, you need to be properly marked." I tilted my head upward to try and see what was going on, my eyes immediately landed on him holding a long rod that had been sitting in some flames. "Wouldn't want any mishaps and accidentally losing an experiment."

I tensed, my eyes growing wise as he picked up the rod and turning towards me. My chest heaved and I tugged my body harder, a sharp pain barely registering in my wrist as he came closer with the rod. The end of the rod I could see the world government symbol on the rod, glowing an angry hot red.

The closer he came the hotter the air became, panicked pleading began to escape my mouth as I tried to move away.

"Uncle Shanks!" I cried, shaking my head. "No, stop! It's hot!!"

The doctor hummed, "Stop moving, I would hate to have to reheat this to try and mark you again."

Then without warning, he used his free hand and held down my shoulder. The other hand jammed the molten hot symbol onto my flesh. A sickening sizzling sound hissed in my ear as I was in too much shock to react at first. A burning smell assaulted my nose as my flesh burned, and the intense burning pain settled down into my shoulder.

A shrill finally escaped me as I tried to move away from the burning rod. However, even when the man moved it away from my arm, the pain didn't stop.

Why didn't the pain stop?

It wasn't on my arm anymore, it shouldn't be burning still.

Hard sobs escaped me as I shook my head and begged for Shanks again. Mom wasn't here, Shanks was supposed to be here. Why wasn't Shanks here?

Nothing bad was supposed to happen.

Doctors were supposed to be good, weren't they?

-End-

.................................................

End of Chapter 86!

Well, that took a very dark turn at the end.... That's just the beginning of the memories Katsu is going to be remembering. Those chapters will likely all be under the warning, as well... it's gonna be fairly bad. I will try not to go into too much details, and for those chapters I will place some kind of warning at the beginning so you are all aware.

How do ya'll think the crew is gonna react? Now knowing for sure that one of Katsu's tormentors is there on the island? Or Katsu? I like reading ya'lls thoughts on the chapter!
