Pokemon Trainer of the Strawhats

Climax! Saving Fishman Island

Yukiko stared at her opponent, he was a large Angler Fishman named Trigger.

Rather than taking him down with her Pokémon, she fought him with her Devil's Fruit.

Then she heard a commotion.

"The Fishman District's Noah?" people were screaming.

"It's heading straight for the plaza!"

"Why is Noah floating above Fishman Island?!"

"It's gonna burst through the bubble!"

"If the bubble breaks...! The neighbourhoods in front of Noah are going to be blasted away by the water pressure!"

"I have no idea what's going on, but we're doomed!" Usopp wailed.

"If all of us were smashed at once, the ocean would probably be dyed red," Robin was commenting.

As a large and strange being named Wadatsumi fell off, a voice boomed from above.

"Decken, you crazy-ass pirate!" Hody hollered at the ark. "This wasn't anywhere in our plan!"

Decken's laughter echoed down from the ark, possibly due to a loudspeaker DenDen Mushi. "Wadatsumi, saving you is impossible now! With my ability, anything I throw will keep flying, crashing through anything it has to until it reaches its target! You'll be our sacrifice! Along with all of Fishman Island, you will die so that we can kill Shirahoshi!"

However, in the confusion....

"Hey, where did Princess Shirahoshi go?!” a fishman barked.

The four of us turned our heads at once, eyes widening when we saw that – low and behold – Shirahoshi had disappeared and was no longer near Surume!

“What?! Princess! Princess Shirahoshi!” Jimbei started looking around quickly for the mermaid princess. I did as well as Robin released my fingers.

“I am over here!”

We looked up at the sound of her voice and – she was hovering in the air above the plaza, a bubble around her middle, arms outstretched.

'I don't believe it. She's trying to get the Noah away!' Yukiko realized.

"Lugia, Kyogre, Tapu Fini, Manaphy! Stick with Shirahoshi and protect her!" Yukiko yelled as the legendaries did so as Shirahoshi swam into the ocean.

As everyone was in their own fights, Yukiko clashed with Trigger as she used her Devil Fruit power.

"Crystal Pulse!" Yukiko said as she used a crystal blast ball similar to an Aura Sphere.

Trigger started to get mad as he took a lot of Energy Steroids and began to act more beastly.

Yukiko dodged as she fought, using her Observation haki, then she focused her energy. And from her back, clear crystal wings like an angel's appeared. "Translucent Wings!"

"Even if you can create wings, you are no match for me!" Trigger yelled. "I'm an officer of the New Fishmen Pirates,  as strong as an Admiral of the Marines!"

"We'll see about that." Yukiko said as she took out a diamond and it shined as she charged forward.

"Divine Diamond Storm!" Yukiko said as a flurry of sharp glowing diamonds struck, hiting Trigger's nerve points, and he was down for the count.

"Strong as an Admiral? Sorry, you weren't even close."

Then she looked around seeing that her friends were done with their fights too.

She just had to wait for Luffy to finish his fight as Hody chased Decken on the Noah.

But from the looks of it, the ship was falling as Hody took down Decken.

It was tense, but I knew with the legendaries up there, Luffy would be fine.

Suddenly after a tense half hour, the Noah somehow stopped.

Looking up, Yukiko realized it was a group of Sea Kings that stopped the Noah! And they were talking to Yukiko somehow along with the Legendaries.
---------
"What? I didn’t do anything – I was just sad,” Shirahoshi argued.

"That's not true." Lugia said to her surprise. "You called the Sea Kings to help, whether you knew it or not, they responded to your desire to save Noah and the island."

"Yes princess, this power had been passed down through your ancestors for a thousand years and has finally returned with you." Tapu Fini agreed.

Then Manaphy turned to the Sea Kings. "Please take the Noah somewhere safe for repairs."

"Of course, Great Sea Prince. It's nice to have you all back." A sea king said.

"You should save your friend princess, he needs help bad." A sea king told Shirahoshi as she went to get Luffy.
----------
While Luffy was bleeding badly and needed medical help. However....

“I can stop the bleeding but he’s already lost a lot of blood!” Chopper said worriedly. “He’s lacking blood!”

"Luffy is the only one with blood type F among us,” Sanji commented.

Although the citizens were hesitant to help, Jimbei walked forward.

The others looked over as he came to a stop.

“Use my blood,” Jimbei said. He pulled back a sleeve. “It’s F. You can have as much as you need.”

“Jinbei!” Usopp exclaimed in relief.

I nodded in determination. “Chopper, what do you need?”

Chopper was cautious. “B-but it’s against the law—“

“Dont forget, I am a pirate! So it doesn't apply to me!” Jinbei snapped back.

Yukiko smiled as the others were preparing the procedure. She held onto Luffy's hand as Jimbei’s blood – as red as a human’s and just as useful to both humans and fishmen – started moving from Jinbei’s veins to Luffy’s through the blood bag hanging between them.

Such a little thing, but this was the first step in creating real peace between humans and Fishmen.

"Jin…bei….”

Luffy’s voice was weak, but it was there, and we all heard it in an instant.

“Luffy-sama, you came to life again!” Shirahoshi cried with relief.

“Luffy!” the rest of the crew called.

“What is it?” Jimbei looked over. “I didn’t know that you were awake.”

Cheers rose up from the outer cliffs of the plaza – the fishmen and merfolk were celebrating Luffy’s survival as well. The entire climate of Fishman Island seemed to sense and move with the shift to joyful voices.

“Hey, Jimbei.” Luffy’s voice was stronger now.

“Hmm?”

Luffy grinned widely and laughed, causing Jimbei and Yukiko to look at him in confusion.

Luffy opened his eyes, that usual determined life back in them. “Join my crew!”
