One Piece : Marine Scientist

"Hahahaha…"

Inside the Fleet Admiral office at Marine Headquarters, Sengoku's laughter echoed.

Reports of victories came frequently from all corners of the sea as various pirates were captured.

During this time, there was hardly any loss of personnel, the Marine barely had to intervene, as the Seraphim handled everything.

The three Admirals leading them found their missions remarkably easy.

Especially the reports coming in from Kizaru…

***

Ten minutes ago, on a small island in the Grand Line, a warship was slowly sailing.

In the next moment

"Admiral Kizaru! We've spotted a pirate ship ahead; it seems to be plundering the town's resources. Upon investigation, it's the Fire Tank Pirates, led by Captain Capone Bege!"

"Oh? I don't recall anything about that!"

"This man hails from the West Blue, is notoriously brutal and possesses a Devil Fruit ability. He is now a pirate with a bounty of over one hundred million."

"Oh? That sounds quite terrifying!" Kizaru pouted and said slowly. "Let's move closer!"

"Yes, sir!"

The warship gradually approached the shore.

At this moment, a man dressed in a pinstriped suit, wearing a top hat and scarf, was leisurely smoking a cigar while listening to his subordinates plunder the town's goods and treasures.

He was none other than Captain Capone Bege of the Fire Tank Pirates, a user of the Castle-Castle Fruit!

A multitude of treasures and goods were being piled in front of him by his lackeys, only to be shrunk and absorbed into his body in the next moment.

Suddenly

"Not good, Godfather! The Marine is here!" A subordinate in a suit rushed over, panic written all over his face.

"Oh? The Marine is here?" Capone Bege raised an eyebrow, a cigar dangling from the corner of his mouth.

"So what? We're not inferior to any ordinary Marine!" His eyes were filled with disdain, but the arrival of the Marine still raised his alertness.

"Everyone, gather and retreat into the castle!"

"Yes, sir!"

Soon, all members of the Fire Tank Pirates assembled and entered the body of Capone Bege castle.

"Let's go!" Capone Bege turned to leave, leaving behind a group of trembling residents.

However, just as Capone Bege was about to step out of the town, a group of Marine personnel blocked his path!

"The Marine… only about ten of them?"

"With such a small force, how could they possibly take me down?" Capone Bege's eyes were indifferent, confident of his victory.

Then, at that moment, a child with white hair, brown skin and a pair of black wings wreathed in flames stepped out from behind the Marine.

"Hmm?" Capone Bege was taken aback "What is that thing?"

But he quickly sneered.

"Even if it's a child, I won't show mercy!"

"Fire!"

As soon as he finished speaking, countless cannonballs seemed to shoot out from his body.

"Boom! Boom! Boom!"

Instantly, the deafening sounds of explosions filled the air.

The ground before them was engulfed in thick smoke and dust, debris flying everywhere!

"Hmph, that should take care of this, let's go!" Capone Bege turned to leave, glancing back one last time.

However, as the smoke cleared, the area was left pockmarked and still emitting smoke.

But it was completely empty!

"What?!" His expression changed drastically!

"Whoosh!"

At that moment, a sound of air being sliced through rang out behind him.

Capone Bege quickly turned around.

It was that child from earlier! He lightly touched the ground and swiftly darted forward!

"What incredible speed!" Capone Bege was startled and quickly ordered.

"Everyone, open fire!"

Immediately, various high-powered weapons bombarded the area again.

However, this time they saw it clearly: The child seemed able to predict the trajectory and landing spots of the cannonballs in advance.

Combined with his incredible speed, he was able to dodge them effortlessly!

Capone Bege pupils constricted as he seemed to realize something.

"Observation Haki!!"

"This child can actually use Observation Haki!" Capone Bege was shocked beyond belief, his feet transforming, moving back at high speed like a tank.

His subordinates continued to fire wildly.

Yet, none of it could stop the child; in fact, as he dodged, he closed the distance even faster!

"He's just a child, how could he be so powerful… wait!" Capone Bege suddenly realized.

"No! This is a new type of weapon developed by the Marine, the Seraphim!!!"

Looking at the child before him, who resembled a younger version of Admiral Kizaru and noting the features of the Lunarian Tribe on him, Capone Bege finally confirmed!

He had never encountered a Lunarian before and didn't react in time, never expecting to face the Marine Seraphim!

"Whoosh!"

In a flash, Seraphim Little Kizaru appeared right in front of Capone Bege!

Various cannonball attacks struck Seraphim.

Logically, at such close range, nearly all enemies would be dead, but Little Kizaru was enveloped in a black aura, as if a shield had formed around him!

It was, in fact, Armament Haki!

"What?!" Capone Bege face turned pale and he immediately unleashed his strongest move!

"Castle—Full Size—Big Father!"

In an instant, he transformed into a massive castle!

"Boom!"

But Capone Bege transformation didn't stop Little Kizaru.

Little Kizaru raised a finger.

His body suddenly leaped high into the air.

His finger, surrounded by Armament Haki, jabbed at the giant castle body!

In that moment, Capone Bege felt a terrifying force pierce through his castle form, causing his entire body to shudder!

His eyes rolled back and he reverted to his original form.

Not only that, but all his subordinates were also exposed.

They all fell from the sky to the ground!

"Thud—"

"Thud—"

With several dull thuds, the Fire Tank Pirates, including Capone Bege, all rolled their eyes back and fainted, completely defeated!

The entire battle lasted no more than five minutes and the Seraphim had only used one move!

He had crushed Capone Bege, a pirate with a bounty of over one hundred million!

"Successfully captured the Fire Tank Pirates!"

"Take them back and report to Admiral Kizaru!"

The Marine personnel appeared, shackling them one by one and bringing them back to the warship.

Meanwhile, Admiral Kizaru hadn't even shown up, he was leisurely sipping coffee on the ship, waiting… And the scene of the Seraphim crushing pirates was similarly unfolding across various seas.

Even on the territories of the Four Emperors, they defeated their officers!
