Kijafa

Dosun, the hammerhead shark fishman, shot himself into the air from the water, intending to use his downward momentum to add force to his mighty overhead hammer strike.

*BAM*

An arm of massive proportions swung through the air in that same moment and swatted Dosun far into the distance. He struck a mountain that almost collapsed on impact.

Robin wore a casual smile as she dismissed the enormous arm. Usopp and Chopper were gawking at her with amazement and stars in their eyes.

Not to be outdone, Usopp started to rapidly fire his pop greens into the water. As the tiny, green spheres struck the water, they expanded to great width in mere moments in the form of giant lily pads. This allowed some solid ground for their devil fruit users to stand on and fight without falling into the water and being helpless to face the fishmen in their natural terrain.

"These lily pads are extremely buoyant, guys! Don't worry about how much weight they can hold, they'll be fine!" Usopp spoke proudly.

Chopper and Zoro took his word for it and made their way into the battlefield. Franky brought out two of his new vehicles, a motorcycle and a tank. Usopp hopped into the tank to make use of its cannon. Then both rolled out onto the lily pads and started attacking the New Fishman Pirate goons who were clambering up onto the lily pads.

Zoro mostly ignored the goons and went straight for the officers targeting Luffy. He was feeling a bit annoyed that he didn't get a decent fight earlier and now that he had all this open space, he wasn't going to waste the opportunity.

Luffy and Jinbe managed to get the chains off of the royal family before the platform beneath them suddenly broke apart and threatened to drop Luffy into the water. Fortunately Jinbe caught him in time and tossed him over to the lily pads.

"RAAAH!" The little cookie cutter shark gremlin bit into Jinbe's leg as he was distracted whilst saving Luffy.

If that wasn't bad enough, Luffy didn't get a chance to land as Hody came bursting out of the water to intercept him. His eyes' sclera had become deep red in color and his hair turned stark white, even his face had become somewhat monstrous.

Luffy stretched his arm to grab something and pull himself away, but he was going to be too late to dodge the shark fishman's deadly jaws.

*SHING*

Fortunately, a cyclone of flying sword slashes carried Hody off his mark as well as cutting him up real good. An unimpressed Zoro said "Keep your guard up, Luffy!"

"Thanks, Zoro!" Luffy said sincerely, getting his feet on solid ground.

The battle raged onwards, few against a hundred thousand strong. Strangely the few were largely unharmed whilst the hundred thousand were being quickly whittled away by them.

"Check this out! Docking initiated! Combining commencing! Behold! General Franky!!!" Franky said from the cockpit of his combination robot suit.

"""So cool~!""" Usopp, Chopper, and Luffy exclaimed in delight.

""..."" Nami and Robin deadpanned in silent judgment.

"Hmph! Consider me unimpressed, Franky!" Cherry called out as she throttled a fishman goon to unconsciousness.

"Oh no…" Robin muttered only loud enough for Nami to hear.

"What did you say?! You just can't appreciate a man's dream! Every mans' dream of a SUPER combination move!" Franky growled with a pointed finger.

"Kukukuku! You call that a combination?! Cabernet, take your position!" Cherry said with a dramatic pose.

"She isn't going to… please tell me she won't… Robin…?" Nami said with clear desperation in his pleading tone.

"I'm afraid so, Miss Navigator…" Robin turned away, unable to watch.

Cabernet landed a few feet to Cherry's left with a huge smile of anticipation on her face.

""FUSION- HAAAA!!!"" Cherry and Cabernet shouted in harmony. They did what looked like a strange dance that ended with them pointing with both hands at the other so that their fingertips met.

A bright flash of light briefly blocked the view. When it faded there was only one woman standing in their place. Strangely she looked like both and neither of the original two at the same time.

Usopp, Chopper, Luffy, and even Franky looked like they were about to faint from their excitement. The ladies of the crew, not so much.

"Haaah…" Cherry/Cabernet let out a flaming sigh.

"What's your name?! Is it Chaberry?!" Chopper excitedly asked.

"I am Kijafa!" She said valiantly. "Now to take care of these evildoers!"

The flames on Kijafa's shoulders went out and she vanished from her place. Thousands of fishman goons received a blow just for them in only a handful of seconds, each of them being rendered unconscious by the sudden attack they had no hope to defend against.

"Go to sleep, you misguided youths! This is not the place for you! You ought to get an honest job instead of galavanting around like criminals!" Kijafa lectured.

It was at this moment that Luffy felt that something was off. "Wait a minute…"

"I am certain that his majesty will reward us greatly with both treasure and food! I will insist he gives both to the poor and downtrodden in the hope that these misdeeds are not repeated!" Kijafa said.

""NO! You can give away the-"" "Food!" "Treasure!" Luffy and Nami exclaimed in simultaneous horror.

"HAHAHA! Your jests are very funny, friends! It would not be very heroic of us to accept a reward that could help others, no?" Kijafa said with all seriousness.

""We're not heroes! We're pirates!"" Luffy and Nami shouted in unison.

Kijafa seemed to have an epiphany. "My goodness! You're right!"

Luffy and Nami heaved a sigh of relief.

"We should turn ourselves into the proper authorities as soon as possible! I cannot believe my two halves have made such an unlawful career choice!" Kijafa spoke with disappointment in herself.

"Just ignore her. She can only maintain that form for about 15 minutes." Robin said, looking very tired.

The battle swiftly came to a conclusion after that. Even with the leaders of the New Fishman Pirates doping with energy steroids as they called them, they didn't stand a chance against the combined might of the Straw Hats, Jinbe, and the royal family, not even in the water.

"I am glad that this all ended without too many deaths." King Neptune said, noting that even with the brutality of the battle, hardly anyone had actually died. "But what to do with all of you?"

As King Neptune's gaze swept over the defeated New Fishman Pirates they trembled in fear. They fully anticipated that they'd be put to death for their act of sedition.

"Please don't behead us! Hody forced us into it!" Was the common sentiment among them.

King Neptune thought for a moment, then began to speak. "You shall-"

"Pshhhh*

The screens that normally broadcast news from the palace came on and showed an electric eel fishman clad in a black uniform.

"Attention, residents of Fishman Island. We, the Neo Marines, have taken control of the palace." Garcelo announced with calm discipline.

"What is this?" Princess Shirahoshi asked under her breath.

"I thought we were done already…" Usopp complained.

"This isn't good…" King Neptune furrowed his brows. The three Princes echoed his expression.

"What's going on, do you know them?" Nami asked.

"That man… Gelato, I think his name was? He's with that new faction in the New World, the Neo Marines. He came to me some time ago and asked me to close off the island from all pirates, and to disavow Whitebeard as well. I refused of course. Pirates are one of Fishman Island's largest sources of business, and Whitebeard is our benefactor." King Neptune explained.

"I have no desire to conquer your kingdom." Garcelo continued. "I came only for one purpose. To eradicate pirates and prevent them from entering the New World. Your King refused to see reason, so now you must suffer for his mistakes. In ten minutes, our super weapon will destroy the bubble surrounding Fishman Island. I suggest you make your escape, or if not, make your peace with death."

The screen cut off. Then the island's residents exploded into chaos.
