One Piece: Trainers on the Straw Hat Pirates

Even if the opponent possesses the power of a legendary hero from the giant race!

"Don't be so arrogant, Straw Hat Boy!!!"

Seeing Luffy charging towards her, Big Mom suddenly let out a sharp roar, then raised Zeus and Prometheus in her hands and swung them forward with a thunderous roar.

In an instant, endless lightning and flames intertwined into a giant longsword, and the intense light illuminated the sky in a blue and red hue.

At this moment, the Conqueror's Haki emanating from the old woman erupted like a volcano, continuously condensing into the Thunderflame Greatsword in her hand!

"The Spear of Elbaf - Mighty Nation!!!"

The woman suddenly tore at her throat and let out a deafening roar.

She raised her giant sword high and slashed down fiercely at the incoming Luffy missile.

In an instant, the entire world seemed to darken, and countless black lightning bolts, as if tearing through the void, filled the area where Luffy and Big Mom were.

The sky flickered and changed color.

Luffy, now transformed into a rocket, finally showed a look of confusion and shock.

"Is this the fighting power of a Yonko?!"

Luffy pondered for a moment.

Even without the fusion of Nika's will, he can still think freely, even in Nika form.

boom!!!

The terrifying shockwave roared outwards in all directions like a world-ending tidal wave.

All living things on Whole Cake Island were affected by this impact, which shows just how terrifying the confrontation between the two was.

The standoff between Luffy and Big Mom didn't last long.

A few seconds later, Luffy, who had transformed into a rocket, suddenly showed a look of pain on his face.

The next instant, under Big Mom's full-force attack, Luffy, who had returned to human form, was slammed into the mountain behind him by the immense force.

Rumble rumble rumble...

The Whole Cake Island trembled violently.

"Mom, did you win?!"

When the higher-ups on Whole Cake Island saw Big Mom send Luffy flying again with a single blow, a group of Big Mom's children immediately showed joy on their faces.

After all, they had been worried for a long time when the old lady was knocked away.

Although they didn't have much of a familial bond with the old lady, their status as her sons was enough to make them thrive and stand out from the crowd in the World of Warcraft.

If the older women are really defeated, they will have no one to rely on.

But Perospero's words were like a bucket of cold water, instantly extinguishing everyone's expectations.

"How could it end so easily!?"

"That guy isn't someone you can just take down so easily!"

Even so, at this moment, a look of anxiety flickered in Perospero's eyes.

At this moment, he hoped more than anyone else that the old lady could win this battle.

Because just now...

He suddenly received an emergency call for help from his own territory, Candy Island.

At this very moment, his Candy Island is under attack by an unknown force.

After making some inquiries, Perospero was shocked to discover...

The islands of his other younger siblings, who also served as island ministers, were also attacked by mysterious people!

Upon closer inspection, it was found that none of the thirty-four islands were spared.

The only difference is the strength of the forces attacking the islands.

However, it seemed that the attackers had already scouted out the distribution of military forces in the Wan Guo Sea, and there was not a single island that could withstand their offensive.

The key is……

Because of the tea party, all the ministers from all the islands are currently gathered on Cake Island and will be unable to return to their own islands in the short term.

Of course, if Perospero still couldn't guess who these attackers were at this moment, then he would have wasted nearly fifty years of his life.

Throughout the entire World of Oceans, a special substance called BON, emitted by special Homies, would occasionally drift down from the sky.

This substance can effectively detect the presence of any unauthorized vessels passing through the international waters.

Despite the unprecedented scale of the attack on the international waters, no alarms have sounded at all.

That can only mean one thing...

The attackers who raided the world were not outsiders.

Instead, they're one of our own, having mastered the method of shielding the BON wave!

All these signs pointed to Perospero as indicating that the force that attacked Whole Cake Island was none other than the Straw Hat Pirates, who had suddenly launched an attack on the Big Mom Pirates at the tea party!

"Were these guys just playing us from the beginning?!"

"That damned bastard!"

Perospero cursed inwardly.

Looking back on all that time they spent hunting for high-quality ingredients to prepare for the tea party where the Straw Hat Pirates joined Big Mom's crew, they were just like a bunch of clowns!

but……

Who would have thought that someone in this world would go back on their word with a Yonko pirate crew?

Even the Straw Hat crew, whose bounties far exceed those of the Four Emperors!

"Could they... actually possess strength commensurate with the bounty?!"

Perospero, who had always thought that the Straw Hat Pirates only received such a high bounty because they had done something unforgivable, has had his thoughts completely reversed in less than an hour.

……

……

at the same time.

While Big Mom's crew members were preoccupied with their own thoughts, Luffy reappeared from the thick mountain wall.

Judging from his appearance at this moment, apart from a few breaths, he didn't show the slightest sign of fatigue.

Clearly, the damage that Big Mom just dealt to Luffy was negligible.

There was no way around it; Nika's power completely surpassed the ordinary Devil Fruit abilities in this world.

For the powerful figures in the One Piece world, this is an even greater blow!

"Hey~ Pretty impressive!"

Upon facing such a formidable opponent for the first time, Luffy's lips curled into an excited smile.

Since entering Gear 5, he hasn't experienced this feeling of "evenly matched" strength for a long time!

Of course, this evenly matched situation is only true for the moment.

Because of the stronger opponent, Luffy's power is also ignited!

"The real battle is about to begin!"

Luffy's eyes narrowed slightly. Without the silly grin brought by Nika's will, he looked more handsome than ever with white flames swirling behind him!

boom……

Dark lightning suddenly struck around Luffy, unleashing a powerful pressure that surged towards Big Mom's location.

It was Luffy's Conqueror's Haki that was being unleashed.

Come and go without indecent!

Since the old lady has shown such sincerity, Luffy feels he should respond accordingly.

"laugh!"

Luffy stomped his feet hard on the ground, instantly transforming the ground beneath him into a soft, waterbed-like surface.

The cascading waves rippled along the land toward where the old woman was.

"Um!?"

Upon seeing this, a look of confusion suddenly flashed across the woman's face.

of course.

Although she didn't understand Luffy's ability, considering Luffy's special characteristics, she still instantly stepped on Zeus and flew high into the sky.

However, what the woman didn't expect was...

Just then, Luffy suddenly swung his fist, which was covered in Conqueror's Haki, and slammed it down onto the ground beneath his feet.

"Rubber Mole Gun!!!"

Before the old woman could react, a huge fist suddenly rose from the ground beneath her feet, with a powerful aura of Conqueror's Haki swirling around it.

"What!?"

Seeing Luffy's attack, the familiar Big Mom's face flashed with surprise.

She truly hadn't expected that Luffy, who wasn't underground this time, could still launch an attack on her in such a way.

Fortunately, she had been on guard.

"Do you think I'd fall for the same trick twice?!"

The old woman frowned and roared, unleashing her Thunderflame Greatsword once more, slashing directly at the sudden giant fist.

As expected, the sharp, lightning-flame greatsword sliced ​​the giant fist formed by the earth in two.

Even with the entanglement of Conqueror's Haki, it was unable to survive even a second longer under Big Mom's full power.

However, upon hearing the old woman's words, Luffy suddenly grinned.

The next moment, endless Armament Haki surged from his body again, replacing the previous Conqueror's Haki and wrapping around his giant fist.
