They both realized—a drawn-out battle wouldn't work. They needed a decisive blow.

Big Mom's ranged attacks, Prometheus and Zeus, were useless against Arthur. And Arthur's lightning, at its current level, couldn't penetrate Big Mom's iron balloon defenses.

Without a word, Arthur unleashed his full Thunder God form.

Lightning surged, his body growing until he matched Big Mom's colossal size.

BOOOOOOOOOOM!!!

Arthur's lightning fists and Big Mom's Haki-enhanced punches clashed, a flurry of blows that reshaped the landscape, Whole Cake Island groaning under the strain.

Big Mom, a true force of nature, wouldn't be easily defeated.

BOOOOOOOOOOOOOOOM!!!

As the ground beneath them cracked, seawater seeping in, Arthur retreated, leaping into the air, his hands raised high above his head.

Zzzzzzt!

Lightning surged towards him, converging in his hands, the energy building rapidly.

He didn't wait for it to reach its full potential, unleashing a smaller, less powerful—but still devastating—Raigo.

"What the—?!"

"That's insane…"

The underworld bosses and the Charlotte siblings, having retreated to their ships, watched in awe and terror.

The massive sphere of lightning, a condensed ball of pure energy, hurtled downwards like a meteor.

BOOOOOOOOOOOM!!!

The force of the impact was earth-shattering. Even Big Mom, her eyes widening, her face hardening, recognized the danger.

Few could withstand such a direct attack.

Katakuri's usually impassive face was creased with worry. Big Mom's massive size made her a slow, easy target. She couldn't dodge an attack with such a wide area of effect.

Just as Arthur thought Big Mom was finished—that she'd be blasted into the sea—she roared, her pink hair standing on end, her massive hands raised above her head, sword energy coalescing between her palms.

Razor sharp—capable of cleaving the very sky!

"Ikoku Sovereignty!"

The sea around Whole Cake Island churned as she unleashed the attack, her furious roar echoing across the waves, its force enough to rupture eardrums, sending weaker onlookers sprawling, blood trickling from their ears and noses.

The massive sword beam, a concentrated blast of pure energy, sliced through the sky, slamming into Arthur's Raigo.

BOOOOOOOOOOOOOOOOOOOOOOOOOOOM!!!

The world warped.

Arthur's Raigo, powerful enough to obliterate half of Whole Cake Island, shattered under the force of Ikoku Sovereignty, dissipating harmlessly in the air.

The clash of their attacks ripped through the sky, scattering the clouds.

Arthur, his eyes wide with a mixture of surprise and excitement, acknowledged Big Mom's power. She was a true contender, a force to be reckoned with in the New World.

"Now this is interesting! This is the New World I've been waiting for! HAHAHAHAHAHA!" His laughter, fueled by adrenaline and a touch of madness, echoed through the air.

He spread his arms, lightning crackling around him, his Thunder God form flickering.

A Thunder Dragon roared.

A Thunder Beast charged.

A Thunder Kirin stomped its hooves.

Zzzzzzt!

"Stampede!"

The lightning beasts, a furious, chaotic mass of energy, surged towards Big Mom.

She wouldn't be outdone. She wouldn't let him take the initiative.

She unleashed another Ikoku Sovereignty—aiming for Arthur in the sky.

As the sword beam collided with the lightning beasts, annihilating them both, she stomped her foot, sending tremors through the already fractured earth, channeling her power, her very soul, into the sea below.

The ocean surged, a massive wave, dozens of yards high, rising up, carrying Big Mom skyward.

"Mamamama! You think you're my equal, Thunder God? Because of your strength? Arrogance like yours—it won't last long in the New World. You don't even know what you're up against! You want to die? I'll gladly oblige! I don't need Whitebeard to finish you off!"

Big Mom, standing atop the monstrous wave, her voice a thunderous roar, unleashed her attack—tendrils of seawater snaking out from the wave, transforming into water dragons, lunging towards Arthur.

This was Big Mom at her most terrifying—a true Emperor of the Sea—her madness, her power, her ruthlessness unleashed.

Her eyes blazed with a predatory hunger.

Arthur, his Thunder God form crackling with power, his expression cold, his gaze unwavering, waited for her attack. He looked like a god of thunder, ready to unleash his wrath.

Nine water dragons, their scales shimmering, their jaws open wide—descended upon him.

Zzzzzzt!

"Two Hundred Million Volts—Discharge!"

Arthur's lightning flared, a blinding blue light engulfing the water dragons.

Sizzle!

The water dragons vaporized, their forms dissolving into a cloud of steam.

But the steam obscured Arthur's vision. Big Mom, riding the massive wave, her aura radiating outwards, her voice a thunderous roar, charged towards him.

"DIE, THUNDER GOD!"

The shockwave from her voice dispersed the steam, revealing Big Mom's Haki-clad fist hurtling towards him.

Arthur's head rang from the force of her voice, his senses momentarily disoriented. A close-range sonic attack like that—without preparation, it was difficult to defend against.

Bang!

Big Mom's fist, hardened with Armament Haki, shattered the air itself—the impact echoing through the air—her attack reaching him in a heartbeat.

Her fist wasn't just imbued with Haki, but also with the combined power of Prometheus' flames and Zeus' lightning—a terrifying combination.

Her mastery of the Soul-Soul Fruit was extraordinary, granting her limitless offensive capabilities—Charlotte Linlin, a force of nature, a true agent of chaos.

Some Devil Fruits were simply destined for greatness—paired with the perfect user.

Whitebeard, the "Strongest Man in the World," his Tremor-Tremor Fruit hailed as the most powerful Paramecia.

Which had come first? The strength—or the fruit? They'd amplified each other, a perfect synergy.

The Goro Goro no Mi had elevated Arthur, its power undeniable—but his own relentless pursuit of its potential had made him a legend in the making.

Big Mom's fists were upon him.

Arthur, grinning, didn't even try to dodge, meeting her attack head-on, his own lightning-wreathed fist a surge of pure, destructive energy.

"HAHAHAHAHAHA!"
