One Piece : Kaido Brother

"A single piece of its trunk made my size grow by two kilometers? Amazing! Absolutely amazing!"

Caesar was ecstatic, his eyes gleaming with a greenish light as he fixed his gaze on the giant elephant's main body!

"This time, I should be able to devour this colossal elephant!"

Caesar split his massive jaws open once more!

Like a predator tearing into a thick slab of meat, Caesar began consuming the elephant's limbs.

As Zou's limbs disappeared into Caesar belly, they were continuously shattered and broken down by the energy within him, transforming into pure bursts of life force.

His size swelled wildly as he devoured.

Thirteen thousand meters.

Fourteen thousand meters.

"Moo!" The giant elephant, surprisingly still alive, let out a mournful cry, yet it did not struggle—as if it had already resigned itself to fate.

At this moment, Caesar heart was filled only with the joy of evolution, utterly unaffected by Zou pained cries.

His mind held but a single word:

Devour!

He continued to consume, his size expanding relentlessly.

Breaking through limits, shattering genetic shackles—it felt as though his very life was evolving, ascending, as if he were undergoing a transcendent metamorphosis!

When Caesar gaping maw finally reached the elephant's torso, the beast pitch-black eye sockets—still devoid of eyeballs—shed two clear streams of tears.

Caesar jaws stretched to their absolute limit, swallowing Zou whole!

Time seemed to freeze.

A terrifying energy brewed within him was on the verge of eruption.

BOOM!!

An endless surge of life force exploded within Caesar and his size skyrocketed once more.

Eighteen thousand meters.

Nineteen thousand meters.

Twenty thousand meters!

His colossal Kunpeng form, pitch-black and monstrous, now stretched twenty kilometers long.

His tail extended beyond Udon Prison, while his head reached the waters outside Okobore Town.

Caesar body had grown larger than the entire Okobore Town, containing an immeasurable amount of life force.

"Ooooh!"

With a resounding cry, Caesar gargantuan Kunpeng form slowly lifted from the sea, rising into the sky!

Golden feathers, radiant as sunlight, sprouted across his body.

His massive, dark fish-like form gradually transformed into a golden bird so vast it blotted out the skies.

The sheer size of this Golden-Winged Great Peng was so immense that even Garp and Sengoku, aboard a Marine warship outside Wano, froze in shock, staring dumbfounded at the sky above.

Wano geographical structure resembled a volcanic crater filled with water, its islands floating at the center.

To enter Wano, one needed an upward force—like the giant koi fish.

When Caesar took the form of the Great Peng, his wings spanned twenty kilometers, casting the sea below into darkness as if night had fallen instantly.

"Gulp."

Garp swallowed hard, speechless at the terrifying sight.

Sengoku face twisted in dread, his voice hoarse as he muttered.

"Garp... this... this can't be Caesar Kunpeng form, can it?"

Garp lips twitched, but no words came out.

He remembered 38 years ago, during his battle with Caesar, when the latter had also assumed the Golden-Winged Great Peng form.

But back then, though the bird had been large—nearly two kilometers long—it was still comparable only to a particularly big whale, far smaller than most Sea Kings.

Now, even from this distance, he could estimate that this monstrous bird was easily over ten kilometers in length.

This size surpasses that of the vast majority of Sea Kings.

'Luffy.' Garp thought of Luffy, his heart sinking to the depths.

Whoosh!

A golden light descended from the sky, landing on the deck.

Countless specks of light converged, forming Kizaru body.

He looked somewhat disheveled with fine beads of cold sweat on his forehead.

"Kizaru, why are you back so soon? Did you find Ryokugyu?" Sengoku asked urgently.

Kizaru pursed his lips, wiped his forehead and glanced up at the terrifying giant bird in the sky before replying.

"Don't even ask. Wano Country is far too dangerous right now. See that giant bird? That's Caesar, right? Sengoku-san, Garp-san do you know what that madman has done?"

Kizaru exhaled sharply, taking a deep breath.

"He tore apart Zunesha and ate it."

"Zunesha?" Sengoku and Garp gasped in disbelief, staring at Kizaru.

Sengoku struggled to speak "Are.... are you sure you weren't seeing things, Kizaru? Zunesha—that walking colossus carrying a country on its back? That elephant has lived for hundreds of years!"

Kizaru shook his head with a bitter smile. "Even if you don't believe it, I witnessed it all firsthand and it still feels like a dream. Not only that, but Kaido and Big Mom have fully regained their strength. The Beast Pirates and the Big Mom Pirates are practically unscathed!"

Sengoku and Garp exchanged glances, rendered speechless.

"This is bad, its really really bad."

Above Okobore town

"WRYYYY!!!"

Caesar raised his golden head and let out a triumphant cry, longing to spread his wings and fly to the ends of the earth without a care.

On the ground, everyone stared wide-eyed, mouths agape, their minds blank as they witnessed the scene.

The residents of Okobore Town had initially prostrated themselves before Zunesha, begging for the divine elephant's forgiveness.

Before they could receive a response, a golden giant bird appeared out of nowhere and tore the elephant apart.

Then, the giant bird transformed into a massive fish, which devoured the elephant, only to change back into a giant bird!

Their minds were utterly incapable of processing what they had seen, leaving them to cower on the ground, worshiping the great beast in terror!

Yamato had stopped fighting, staring blankly at the sky, her strength drained.

At the edge of Okobore Town, Momonosuke collapsed to his knees, his face drained of color.

Whoosh!

The golden bird that blotted out the sky rapidly shrank, revealing Caesar towering, domineering figure as he descended like a meteor.

BOOM!

The earth split apart.

With a wave of his hand, Caesar dispersed the billowing dust with a violent gust of wind and strode forward.

He looked the same as before, yet even more wild and overbearing.

His terrifying physique now faintly shimmered with a black-gold luster, every movement perfectly embodying the pinnacle of power.

Caesar swept his gaze across the scene. Wherever his eyes passed, people knelt on one knee, their faces filled with fervent reverence.

His vision pierced through space, landing on Momonosuke.

In the next moment, Caesar vanished, reappearing right in front of Momonosuke.

Momonosuke trembled all over, his face drained of color as he stared at the demonic figure of Caesar.

His mouth hung open, lips quivering like leaves in an autumn wind.

"Insignificant insect, even though you can command such beast but you still remain nothing but insect. Since you survived the great battle days ago, you should understand this truth—trash like you only prolong your wretched existence by groveling."

Caesar expression remained frosty as he slowly extended one massive hand.

"NOOOOOO...!" Behind them, Yamato face turned deathly pale as she reached out with a piercing scream.

Yet not a flicker of emotion crossed Caesar face.

The enormous hand pressed down upon the air above Momonosuke's head!

Layer upon layer of air compressed under terrifying pressure, like a thousand-meter mountain collapsing instantly!

Momonosuke eyes became a swirling maelstrom of despair, hatred, malice and primal terror.

BOOM!

Dust exploded from the impact as the ground cratered dozens of meters deep.

Within the pit remained only a human-shaped smear of pulped flesh.

Thud.

Yamato collapsed to her knees, staring blankly utterly hollowed.

[A/N : ngl momonusuke was super annoying somehow in this fic, finally he die]
