Deep beneath the surface of Wano Country, within the hidden, ancient world that housed the legendary battleship Pluton, a fierce battle reached its climax. The air hummed with a heavy, oppressive energy that only those with the strongest wills could withstand.
On one side of the battlefield stood a figure that commanded respect from across the seas: Whitebeard. The legendary pirate was a vision of raw power, his massive frame enveloped in a thick shroud of Conqueror's Haki. His legendary polearm, Murakumogiri, crackled with violent streaks of red lightning. Every movement he made was reinforced by the devastating vibrations of the Tremor-Tremor Fruit, a power capable of shattering the very air.
Facing this titan were four members of the Tobi Roppo from the Beasts Pirates: Fūz Fū, Ulti, Sasaki, and Page One. They, too, were surrounded by the aura of Conqueror's Haki, though their mastery varied. Ulti stood out among them, her weapon glowing with the distinct, black-red discharge of Haki imbuement. Remarkably, all four warriors possessed the same vibrating glow of the Tremor-Tremor Fruit upon their weapons, a sight that would have shocked any observer of the Grand Line.
With a deafening "Boom!" that shook the foundations of the underground cavern, the four subordinates launched a coordinated strike. The combined force was immense, colliding with Whitebeard in a flash of light and sound. Under the sheer pressure of the assault, the figure of Whitebeard began to blur and fade, eventually dissipating into thin air like mist.
"We did it! That was amazing!" Ulti cheered, her voice echoing off the metallic hull of the ancient ship. She jumped slightly, her excitement overcoming her fatigue.
Beside her, the other three were panting heavily, their bodies covered in sweat and grime. Despite their exhaustion, they couldn't hide the grins on their faces. They had just accomplished the impossible. Even if it was an unfair four-on-one fight, they had managed to defeat a simulation of the strongest man in the world.
It had been six months since they first arrived in this secret place. They hadn't come here to hide under the protection of Big Brother Kaido; instead, they had earned their place through sheer grit. Over the past year and a half, thanks to the abilities of Lily's Time Fruit and the brutal physical training Kaido had put them through, their bodies and Haki had reached a level where they could even survive the intense heat of the underground lava.
When Kaido first brought them down here, they were stunned. They never imagined such a majestic and terrifying world existed beneath the soil of Wano. But there was no time for sightseeing. As soon as they arrived, the deceased Whitebeard had appeared before them, causing them to jump back in shock.
Kaido had quickly stepped in to explain. He told them that this was the power of the Ancient Weapon $Pluton$. Through its mysterious technology, the legendary Whitebeard had been revived in a phantom form. Most importantly, this version of Whitebeard was under Kaido's total control, serving as the ultimate training tool.
The early days were a nightmare. Against a Whitebeard at his absolute physical peak, the four were little more than punching bags. They were beaten, bruised, and broken daily, with no way to fight back against the sheer scale of the Emperor's power. However, their year of hellish training had given them bodies of iron. They endured the punishment, and slowly, the latent power within them began to stir. They started to manifest the Tremor-Tremor Fruit abilities and combat techniques that Kaido had shared with them.
After half a year of constant combat, they could finally trade blows with the legend. Their strength had officially ascended to the rank of Top Commanders, the elite of the New World. Yet, a gap remained. There was still a massive wall between a Commander and a true Emperor of the Sea. That wall was the advanced application of Conqueror's Haki—the pinnacle of power.
Originally, only Ulti possessed this rare gift. But a month ago, Kaido had appeared with a mysterious energy, bestowing it upon the others. Suddenly, Fūz Fū, Sasaki, and Page One found themselves wielding the very power they thought was reserved for the chosen few. Kaido called it Pluton's gift.
Fūz Fū didn't care much for the origins of the power. In the past, he might have been ambitious or curious about the Ancient Weapon, but his life had changed. Since the birth of his two children, Fūz Jo and Fūz Manny, his old dreams of conquest had faded. He had been a philanderer in his youth, never caring for the women he stayed with, but his own flesh and blood changed him.
His daughter, Manny, was his world. To Fūz Fū, she was a treasure more valuable than anything on the Grand Line. If someone offered him the coordinates to Laugh Tale in exchange for her, he would have laughed in their face. The children were already showing signs of greatness; at only two years old, they possessed the leg strength of wild animals.
He knew his own genes were strong, but not this strong. He realized this power came from his wife, Sinamon, who carried the legendary bloodline of Big Mom. Fūz Fū had settled into the role of a father, shedding his former coldness. He realized that the only way to keep his family safe was to ensure the Beasts Pirates remained at the top of the food chain. As a former agent and a traitor to the World Government, he knew his children would be hunted if the crew ever fell. This protective instinct fueled his Haki, proving that a change in spirit can lead to a massive leap in physical power.
Sasaki had undergone a similar transformation. In the past, he was a loud, unreliable drunk who often made mistakes. Marriage to Galette had tempered him. As a Fishman, Sasaki had spent his life dealing with discrimination and loneliness. He didn't have the same emotional foundation as others, which had bred a hidden bitterness in his heart.
However, the Beasts Pirates gave him a home, and Kaido gave him respect. Galette gave him love, and his children gave him a purpose. He became composed and strategic, thinking of ways to protect his family without needing Kaido's direction. He was no longer just a brawler; he had the presence of a Marine Admiral.
Ulti and Page One remained the simplest of the group, driven by their sibling bond and their loyalty to Kaido. Being only 22 and 20 years old, they were in the prime of their growth, soaking up experience like sponges. If the Tobi Roppo had reached this level, the Four Calamities were undoubtedly even more terrifying.
Deep inside the Pluton battleship, Kaido stood with his Four Calamities before a massive, semi-transparent furnace. This was the heart of the Ancient Weapon. Inside, a violent crimson energy pulsed like a heartbeat, flashing with red lightning that looked dangerously similar to a Mother Flame. The power room hummed, signaling that the era of the old world was coming to an end.
