Fishman Karate
Gin and Sanji stood in front of Kuroobi.
"Now we have to help Luffy," Zoro said getting up.
"Don't worry! Nami's sister probably got him by now," Gin responded.
"Why don't you do us a favor and go see why Luffy isn't awake yet," Sanji responded.
"No, I can still fight!" Zoro responded.
"You're not going anywhere Kuroobi yelled moving in for a punch.
Gin took out his tonfas and blocked.
However Kuroobi punched enough force to send Gin into the water.
"Hah! Now I can fight in my own zone!" Kuroobi said as he jumped into the water.
"Dang it Gin!" Sanji responded as he jumped after both of them.
"Idiot! What are you doing?" Zoro yelled.
"You should realized that you are just humans!" Arlong laughed, "Those two are doomed!"
Kuroobi was moving in to strike Gin who took out his Tonfas too guard.
"Oh no you don't!" Sanji thought as he did an underwater flip for a kick.
Sanji kicked Kuroobi, but it didn't seem enough to do damage.
Kuroobi did feel it as he turned around and grabbed Sanji.
"That won't work! Your strength is cut in half underwater," Kuroobi responded.
Gin moved in to strike, but Kuroobi's ponytail moved and wrapped around Gin and threw him into Sanji.
"You're wasting your energy and time," Kuroobi responded, "It's only a matter of time before you humans need air."
Kuroobi swam in and started punching and kicking Sanji and Gin.
It didn't help that Gin was still tangled in Kuroobi's ponytail, and everytime Sanji tried to help, it just got them both beat up.
"I need to cut myself free," Gin thought.
Sanji moved in to try to free Gin again.
Kuroobi attack Sanji in the process.
This gave Gin a chance put away both of his tonfas, to reach into his jacket inner pocket and pulled out a knife.
Gin used the knife to cut himself free.
"What?" Kuroobi responded.
This gave Sanji and Gin both a chance to swim up for air.
"Nice job Gin!" Sanji responded.
"Thanks," Gin responded, "We should fight him on land where we have the advantage."
"Good idea," Sanji agreed.
However something yanked them under so quickly that they only had a minute to gather air in their mouth.
It was, of course, Kuroobi that pulled them under.
"I'm not about to let you get back on land just yet!" Kuroobi responded as he punched both and forced them into the ocean floor."
Sanji and Gin struggled to keep their breath.
"After this, I'll kill that rubber man instantly, and then I'll kill that long nose boy, Zoro, and every villager who try to go against us. And for that, I'll make sure that betrayer Nami don't live peacefully. And nothing you two do will make a difference," Kuroobi said, "All humans are weak! And it seems you can't take changeable water preasure so, if you go deep into the ocean, you will explode."
Kuroobi grabbed them both swam up for another dive hit.
Sanji pointed at Kuroobi's gills.
Gin nodded as took out another knife he had hidden on him and stabbed Kuroobi in the gills.
"Ahh!" Kuroobi yelled in pain as he let go of them.
Gin and Sanji use the time to swim up to the surface for air.
They reached land.
"Good move Gin," Sanji responded.
"Thanks," Gin responded.
However Kuroobi swam up to the surface and jumped onto land.
His gill slits were still bleeding but he took a stance.
"You don't seem to get it! It doesn't matter if I'm on land or in water, with my fishman Karate, I will kill you!" Kuroobi responded, "My punches has the power of 1000 punches."
However, Sanji moved in and hit Kuroobi with so much force that he was pushed into the ground.
Before Kuroobi could get up, Sanji kicked kicked him in wounded gills.
Sanji kept kicking Kuroobi until he hit the wall of the building.
"I should of seen that coming," Gin laughed.
"Of course. That fishman insulted Nami, and now he got his just desert," Sanji responded.
A/N: Sorry about the long update. I had been updating other stories before I stopped, but September been a hard month for me. It didn't help that my grandmother died Friday.
I don't expect sympathy from all my readers, but at least take my advice, spend time with your family and love ones, and keep in contact with those that don't live near you, because you never know when you'll never hear from them or see them again.
Also, one thing about being on the 61st chapter and yet not being in the Grand Line yet. Keep this in mind, the reason I'm not in the Grand Line yet is because I wanted spread out the archs in One Piece in more chapters with each action that takes place in the series, and not just try to jam all of the archs into few chapters like I usually do. If you have a problem with that, tough.
Also for those that pointed out mistakes in character's I used. Thank you. This is my first One Piece only based fanfiction, and after updating Ninja Piece before starting this story, mistakes are expected (especially since Ninja Piece is a crossover of One Piece and Naruto).
