Authors note: Im going to be skipping a lot of the cannon stuff since i want to mainly cover what changes. I dont want it to be a story where it takes 7 hours just to get to the actual what if. Also i apologize for how short the Rayleigh vs Luffy fight was and i promise to make the other fights as entertaining as possible. Final note, it will take me a while to release the next chapter since i forgot how punk hazard went since its been so long so im gonna have to rewatch it and im not looking forward to it since punkhazard was dragged on for way too long in my opinion.
Everything goes as cannon up until the straw hats fight Hordy and the fishmen*
"HELP ME, LUFFY-SAMA" Screamed the mermaid princess.
In a flash Luffy shot towards hordy and landed a bone shattering kick right into his gut. Causing him to spit out a lot of blood.
With that blow Hordy was sent flying into the cliff shattering the rocks making everything collapse. The other fishmen looked in shock.
Luffy landed and the straw hats did their signiture walk in.
"Oi marimo dont worry ill save u" Smirkes the love cook.
"You sure u haven't lost a lot of blood from those pathetic nosebleeds that pissed off the fandom?" retorted the swordsman.
As the two continued to bicker Luffy walked up with his straw hat covering his eyes. He pushed the two arguing aside as he walked forward with everyone wondering what he would do.
Luffy raised his hat and released all of his conqueres haki onto every single fishman. This in turn cause all 100,000 Fishmen to pass out.
Everyone looked shocked. A single man who could knock out an entire force of 100,000 fishmen without lifting a finger was pratically unheard of.
"Hordy right? im gonna give u 5 minutes. 5 minutes to attack me. I wont block, attack or dodge. I wont even put up any tyoe of defence. If you are unable to defeat me i will just beat you" Spoke Luffy.
After hearing this everyone thought that Luffy was insane. No matter how strong someone is, if the take a beating for 5 minutes straight they are bound to be taken out.
"Luffy thats too reckless" Shouted Nami
"Shes right Luffy, you might have trained with the dark king but that doesnt make u invincible" Continued Robin.
"Listen to the ladies Luffy" protested Sanji.
"Dont worry guys, i know what im doing" replied Luffy.
"Hah! Ill take you up on that offer straw hat" Screeched Hordy.
In a flash Hordy charged towards Luffy at break neck speeds. When he reached Luffy he landed a bone shattering fist into luffys face sending hin flying back.
Hordy then followed up with watter bullets that smashes into luffys back. This made The straw hatted man fly into a mounting creating a large crator.
Hordy grinned as he ran up to the crater to then land a barrage of punches into Luffy. He then followed up with a kick to the sternum sending Luffy flying up into the sky.
Hordy then prepares his spear and started spiraling up towards luffy. When he reached him he plunged the blade into luffys back causing a large amount of blood to shoot out from the wound.
"LUFFY!!!' shouted the straw hats.
"LUFFY-SAMA!!!" Cried shirahoshi.
"3 minutes and 44 seconds left" stated the swordsman.
"We should probably take down the ones that are getting up now" said the cook.
With that the straw hats used their new abilities to take down the fishmen that started to get up.
When we go back to luffy we see that he is being attacked from all angles by hordy who was spiraling with his spear. This inturn made a lot of Luffys life fluid to be forced out.
3...2...1...Times up!" stated Luffy. With that the straw hatted boy cocked back his fist coated it in basic armament haki and shot it towards hordy sending him crashing down toward the floor.
This got everyones attention as luffy landed back onto the ground.
"Well Hordy, u see that you were unable to beat me... Too bad" said Luffy.
Hordy slowly stood uo with blood leaking from his mouth and nose.
"WHAT DO YOU KNOW! YOU'RE JUST A WEAK HUMAN THAT HAS NO BUSINESS IN FISHMAN AFFAIRS" screamed Hordy.
Luffy with his eyes shadowed by his hat coated his fist in ryo. Shot it backwards to the other side of the battlefield. In that moment his entire arm caught on fire. When that happened luffy jumped foward at light speed. Just before his attack hit he shoutes "Red Hawk"
Luffys fist shot foward into Hordys gut sending flames and shockwaves all through his body this made his eyes go blanc and a tremendous amount of blood to shoot from Hordys mouth, nose, eyes and ears.
Without a doubt the terrible fishman Hordy jones was dead. he was killed by the infamous Straw Hat Luffy with a bounty of 400,000,000 Berries.
The fishmen and mermaids stood in awe at the power of Straw hat Luffy. This made Luffy laugh as he collapsed from blood loss.
Chopper ran over in desperation to save his captain.
"Is anyone type B here? He needs a blood transfusion" Screamed Nami.
Everyone stood in silence as they realise that no fishman or mermaid wanted to give their blood to a human.
"I am" stated a familiar voice.
The strawhats looked behind them as they saw Jimbe.
Jimbe laid down and the blood transfusion started.
"Hey Jimbei... Join my crew" stated Luffy.
Silence...
