Proud Four Emperor, Biochemical Bomb

"The situation seems urgent—"

The beheaded Doflamingo looked at Luffy and Law before him, and Kyros, who was freeing King Riku from his restraints. These three were not to be trifled with, and there were others as well.

After being nearly killed by Nami in one hit, Doflamingo dared not underestimate the Straw Hat crew again. However:

"Your navigator and that strange ship are at sea, right? Hee hee hee hee~~~"

As another Doflamingo emerged from the adjacent room, the beheaded 'Doflamingo' also stood up.

"I am Donquixote Doflamingo!"

"My ambitions haven't been realized yet, how could I possibly be defeated by you little brats? It seems it's time to make a firm decision!"

As the entire palace shook violently, the area where Doflamingo was located rapidly rose higher! Luffy, who wanted to rush up, was immediately blocked by the rocky structures controlled by Pica's Devil Fruit ability.

As the real Doflamingo gritted his teeth, countless threads shot into the sky from the neck of the decapitated 'Doflamingo'! Through the threads stored by 'Shadow Knight', Doflamingo was able to unleash his ultimate attack.

"Birdcage!!"

The countless threads that make up the doll are ejected into the air like a volcanic eruption. When these thousands of transparent threads reach a certain point in the air, they immediately fall in all directions like a meteor shower. The threads that fall to the ground extend from one point in the air to the point on the ground, forming a huge arc-shaped Birdcage from the air to the ground.

"Here we go,"

Roman, who had brought Usopp to the ground and handed him over to Chopper, watched the lines descending from the sky and nodded in satisfaction.

"Closing the door to beat the dog"—with this move, Doflamingo's house won't even have a place to run. Brilliant!

"Luffy, Roman,"

Just then, a crisp sound suddenly came from their wrists, startling Roman and Luffy, because:

"Nami!"

"What is it?"

Nami wouldn't contact them at this time unless it was an urgent matter. After all, if she were to be distracted by her own people during a battle, wouldn't she suffer an unjust defeat?

"A ship is attacking us,"

Nami's voice rang out amidst the booming cannon fire, causing Roman's expression to change! Because he had suddenly remembered something he had forgotten:

"Judging from the flag, it's the Big Mom Pirates. Should we retreat or—"

"Who cares what kind of pirate crew they are, fight back!"

Luffy's voice rang out immediately, while Roman frowned and then explained.

"The BIG MOM Pirates are Big Mom than Charlotte Linlin, one of the Four Emperors."

"No matter who it is, they cannot hurt my comrades!"

Luffy answered without hesitation, and at the same time:

"Roman, you should have gotten there by now, right?"

"... Exactly."

With a rustling sound, Roman in the arena began to disintegrate into scattered pieces of white paper, while on the deck of the Sunny Merry in the ocean next to Dressrosa, the flying papers began to form Roman's body.

This is the original body!

"That's settled then, the 'Big Mom' Pirates are yours, Roman."

Luffy's voice remained steadfast.

"Give them a good beating!"

"This is the captain's order."

This is also a responsibility that the captain must bear.

With this order, Luffy's own head will become the target of the entire 'Big Mom Pirates'. While other crew members might still have the possibility of defecting, the captain will definitely be used as a warning to others.

"Good."

Roman glanced back at the Birdcage that was beginning to close in the distance. This thing could block everything in and out, and even interfere with the transmission of Den Den Mushi. —Originally, it was Doflamingo's 'coffin' that Roman had prepared for himself, and Roman had even wanted to join in the fun. Now it seemed:

Nami,

As Roman looked to the side, the orange-haired girl nodded.

"Let's finish this battle quickly, maybe we can catch up with Luffy's 'big show'."

As the Birdcage fell, even the communication Paper Phone that Roman created using his 'Flower-Flower ability' was severely disrupted. However, Roman wasn't worried. Not only was the Straw Hat crew inside basically at full strength, but Luffy Fourth Gear alone was enough to easily defeat Doflamingo!

It can't be that another group of experts are just pushing Birdcage around without fighting, can it?

As for the Big Mom Pirates—

Amidst the thunderous roar of cannons, a massive pirate ship, whose figurehead alone resembled the 'Sunny Merry,' gave chase.

"Pa la la~~Pa la la~~"

The bow features a cartoonish smiling face wearing a crown, singing and rolling its eyes as it stares at the 'Sunny Merry' ahead. Giant biscuits are embedded in the keel, the hull is covered in cream, and the cabins are like giant cakes...

The entire ship was filled with a 'dessert' style, which made Roman feel nauseous just by looking at it.

"I don't dislike desserts, but hot pot is also good."

"However, everything needs to be done in moderation. So:"

Roman, still in his magician pose, looked behind him at the enormous 'Queen Mama Chant' and the two figures, one tall and one short, on the deck.

"Baron Tamago, Pekoms, what brings you here?"

"It seems we've finally found a smart person who can remember our names."

Baron Tamago, who resembled a compass, elegantly removed the cup of Black Tea from his head and took a sip.

"Enough with the small talk, hand over Caesar. He still owes 'Mother' a promise, otherwise we'll have to settle this with 'pirates'."

Rob!

"That's a real shame,"

Roman, dressed as a magician, shook his head.

"My captain just gave the order to 'give you a good beating,' so:"

As the book at Nami's waist flew up and flipped open with a rustling sound, dark clouds began to gather in the sky! The ocean currents beneath the ship surged and roared! Gale-force winds howled all around! Violent natural disasters were protecting the Straw Hat crew.

Armed with the might of heaven and earth, and facing the enemy with calamity, the small 'Sunny Merry' actually outshone the massive 'Queen Mama Chant', which was as large as an aircraft carrier! This caused Baron Tamago's face to darken on the ship's side.

"This is not a wise choice..."

"I'm sorry,"

Roman adjusted his top hat.

"Our captain's goal is to become the 'King of the Pirates,' so we've been 'enemies' from the start, right? Besides:"

"Let go of, let go of this genius—?!"

"Oh my god! It's the Big Mom Pirates!!"

When Caesar, who was being escorted out by Brook, looked up, he was instantly paralyzed with fear! What's it like to have a creditor come knocking on your door? And one you can't fight back against, a creditor with the World's Greatest intelligence network: the Big Mom Pirates.

"Don't hand me over! Keep me to trade with 'Joker' or even Kaido..."

"Don't worry, I won't let you fall into the hands of the 'Big Mom' alive."

Roman's words had just relieved Caesar, but the next second he suddenly realized something!

"Hey, hey, hey, what do you mean—"

"Arm up!"

A metallic sheen instantly appeared on his hands, one hand gripping the back of the neck, the other the spine! Roman lifted Caesar high above his head, and at the same time, intense cold air rapidly covered Caesar's entire body, freezing him into a crystal-clear and hardened state like millennia-old ice.

"If you want them, you can have them!"

With a powerful throw from Roman's arms, Caesar, frozen into an ice Caesar, flew hundreds of meters like a cannonball and crashed into the deck of the 'Queen Mama Chant'.

?!

"Retreat immediately!!"

In an instant, Baron Tamago's expression changed drastically. As he retreated, he didn't forget to pull Pekoms next to him along.

Boom!!

As the 'Frozen Caesar' slammed into the deck of the 'Queen Mama Chant' like a cannonball, it indeed exploded with a deafening roar! Countless fragments of hard material, mixed with icy flames, emitted sharp, piercing sounds, sweeping wildly in all directions like a metal storm. The nearest cabin and dozens of Homies were instantly torn to shreds like paper in the explosion.

"Damn madman!"

Baron Tamago, retreating at high speed, cursed without regard for his manners. A large amount of purple smoke with a pungent smell spread out and quickly enveloped the ship. The combat members of the 'BIG MOM Pirates' on board changed their expressions at the same time and desperately fled out of the area covered by the purple smoke.

One unfortunate middle-aged man, dressed in a dark blue shirt, yellow shoulder pads, and a metal helmet, was standing nearby. Although he was tough, as the person closest to the epicenter of the explosion, he was covered in countless cuts and scratches from shrapnel!

Although each wound was shallow and only superficial, the blood that flowed out was all purple. He forced himself to retreat several dozen meters before finally collapsing onto the deck, his entire body covered in purple skin. The lively flowers, plants, and trees around him, with their human-like faces and features, withered and died in agony, withered leaves and fallen petals falling like rain. A large group of 'Homies' lost their 'life' on the spot.

"Damn it, Lord Haifat has been poisoned!"

"The ship's doctor! The ship's doctor is over there!"

"Antidote—"

Immediately, combatants shouted that the armored giant was named Charlotte Heifet, the twentieth son of the Charlotte Family. Although he was tall and imposing, his strength... well...

The guy who was taken down in Jinbe move by Jinbe after he came ashore.

"The Straw Hat crew are lunatics! You're asking for death!!"

"In the name of 'Big Mom,' I will destroy you—"

Facing a group of Big Mom Pirates officers on deck, each displaying their unique abilities to disperse the poison gas and erupting in fury, Roman calmly waved his hand.

"You fired first, are you saying we can't retaliate?"

"It seems the 'Big Mom Pirates' are nothing special after all, so arrogant as to think the enemy would surrender?"

Caesar is a 'Gas- Devil Fruit user,' not a 'Self-Destruct Devil Fruit user.' The reason he transforms into a poison gas bomb is, of course, because:

The instant he was grabbed by Armament Haki, Roman simultaneously used his 'Ice-Ice ability' and 'Magma-Magma ability'. One was poured into Caesar's body from the outside, the other from the inside. The surface was frozen solid, as hard as metal, while the inside was filled with terrifying temperatures of thousands of degrees and raging magma ready to erupt at any moment!

Caesar had absorbed the deadly poison of the 'Death Country,' and every cell in his body was filled with it. Had his heart not been removed by Law, he would have been an extremely dangerous individual. In this state, he had become a terrifying high-explosive gas bomb, every piece of bone and flesh carrying a deadly poison that would kill anyone hit, and all the evaporated flesh turning into lifeless purple toxic smoke.

While each of the abilities Roman 'recorded' from others may not be particularly strong individually, when combined, they can unleash a power greater than 3! Not only are they powerful and versatile, but they also have no weaknesses.

"Not bad power,"

Roman turned to look at the two people on the boat. Normally, he wouldn't use such ruthless methods to consider the feelings of others, but if it were:

"Remember to keep this a secret from Luffy and the others, after all, this kind of scene is a bit unappetizing."

"Okay, but it's also a way to make use of waste."

Nami nodded calmly. In her eyes, a guy like Caesar who experimented on children and even poisoned and controlled them deserved to be shot as many times as he wanted!

"Oh ho ho, I understand, Mr. Roman."

Brook didn't say anything—don't forget that all his former companions died from poisoning, and he had no liking for Caesar, this inhuman mad scientist.

"Well, next."

After gaining the upper hand, you'll face a fierce counterattack from the other side.
