"You bastard…"
The simultaneous detonation of dozens of Micro Vibration Cores within her body—along with the overwhelming pain and loss of control—completely ignited Big Mom's feral nature.
"Get the hell away from Mama!!!"
She unleashed a heart-rending roar. The monstrous strength hidden within her colossal frame erupted outward, blasting away the surrounding rubble that had begun to collapse in around her.
Almost the instant she tore free from the internal destruction, her burning eyes locked onto Gern.
Both hands gripped Napoleon—restored to its original shape yet still wrapped in flames and crackling lightning.
She poured every ounce of her power and Haki into it, drawing the blade back in a fully charged stance.
"Elbaf's Spear—Wei Guo!!!"
The giant sword swung.
A spiraling shockwave of sword energy—over dozens of meters in diameter—exploded forward. It pulverized everything in its path and tore through the air at a speed that surpassed sound itself.
Where it passed, the ground was carved into deep trenches. The atmosphere screamed in piercing shrieks. Its range was so vast that it sealed off nearly every possible escape route.
Facing this giant clan secret technique—capable of cleaving an entire town in two—Gern's gaze sharpened.
He did not retreat.
He advanced.
His left hand clenched into a fist. Vibration particles coiled around it, fused with Armament Haki.
"BZZZ—BOOM!!!"
With a single, straightforward punch, he struck forward.
The space before his fist seemed to solidify—then shattered like glass under unbearable pressure.
The spiraling Wei Guo shockwave collapsed from its center point, violently dismantled by a far more savage and domineering force.
The energy scattered into chaotic currents and dissipated into nothingness.
One punch—Wei Guo destroyed.
The recoil from the impact launched Gern upward.
He surged into the sky, rising even higher than Big Mom.
Both hands gripped Bahuang. He raised the black blade overhead as dark-purple Conqueror's Haki and pale vibration particles gathered, compressed, and condensed around it with frenzied intensity.
"Heavenquake…"
He brought the blade down toward Big Mom below.
"…Tyrantfall!!!"
As the sword descended, the air along its path was completely evacuated, leaving behind a vacuum corridor.
The instant the slash collided with Big Mom's crossed arms—both coated in top-tier Armament Haki—
"BOOOOM—!!!"
A destructive sphere of energy, laced with dark-purple lightning and pale shockwaves, erupted outward from their point of contact.
Blinding light swallowed everything.
The deafening roar was so overwhelming that even Katakuri and the others, who had already retreated far away, felt their eardrums ache.
The spherical shockwave blasted outward, tearing away what remained of the Cake Castle's ceiling and walls as if they were made of paper.
"Prometheus! Zeus! Heavenly Flame Thunder!!!"
Despite being forced onto the defensive—arms locked in place to block Gern's descending slash—Big Mom barked out an order.
"Yes, Mama!"
Floating at her sides, her Homies responded instantly.
Zeus and Prometheus poured out every ounce of their energy.
Savage violet lightning intertwined with all-consuming flames, fusing into a torrent of destructive power. The blazing thunderfire roared downward toward the center of the explosion—toward Gern's position.
"BOOM!!!"
Two landscape-altering forces collided violently at the peak of Cake Island.
An even brighter flash erupted—like a second sun rising above the island.
A raging storm of energy tore through everything.
Gern and Big Mom were completely swallowed by the cataclysm.
...
Not far away, as the all-consuming torrent of destruction slowly began to dissipate—
Katakuri and the others, still in urgent retreat with their siblings in tow, could not help but stop.
Their hearts climbed into their throats.
They stared toward the epicenter of the explosion, desperately hoping to see their mother's towering figure still standing.
Hoping the battle had ended.
However—
"BASTARD!!!"
A roar laced with pain and fury exploded from the clearing smoke.
An enormous figure was hurled skyward as if struck by invisible force.
It was Big Mom.
Her condition was far from pristine.
A wisp of black smoke drifted from the corner of her mouth. Her ornate dress was scorched and torn in multiple places. Clearly, she had suffered heavily in that earth-shattering clash.
Before Katakuri and the others could even process what they were seeing—
"Whoosh!"
A second figure shot upward from the dissipating smoke below at an even greater speed.
Like a purple meteor, Gern accelerated past Big Mom's ascent, overtaking her midair and appearing above her in an instant.
It was Gern.
His left hand slid along the blade of Bahuang.
As his palm traced its length, dark-purple Conqueror's Haki wrapped around the black steel once more, resonating with a low hum.
Even more terrifying—
Countless microscopic vibration particles were compressed along the blade's edge at unprecedented density.
They formed a rotating, contracting pale ring of energy.
As he ascended, the blade left behind streaking arcs of distorted light.
At that same moment—
"Blazing Roar Cannon!!!"
Big Mom screamed in hysterical defiance, making her final stand.
Prometheus flung his fiery maw wide and bit down on the base of Napoleon's hilt.
Zeus stretched and contorted, allowing the sword's sharp tip to pierce straight through his lightning-formed body.
The powers of all three converged violently.
A tri-colored ring of energy—blazing fire, raging thunder, and overwhelming Haki—formed at Napoleon's tip, radiating heart-stopping destruction.
"BOOM!!!"
Big Mom swung the giant sword.
The energy ring compressed and erupted into a beam—a hyper-condensed tri-colored laser of annihilation.
Where it passed, space twisted and warped. Everything in its path disintegrated.
It shot downward from above at blinding speed toward Gern, who was still mid-air, gathering power.
This was Big Mom's ultimate combination technique—her final trump card—uniting the power of her three great Homies with her own Haki.
Facing the laser that could pierce through anything, Gern's eyes did not waver.
He simply pushed the power condensed upon Bahuang even further.
The sky dimmed completely.
"Heavenquake—Sky Rend!!!"
Gripping the blade with both hands, Gern reached the apex of his ascent.
Facing the incoming Blazing Roar Cannon.
Facing Big Mom.
He performed one simple upward slash.
The instant the black blade cut—
the world seemed to mute itself.
Then space wailed.
"Crack… crack-crack-CRACK—!!!"
From the edge of Bahuang's blade, the blue sky itself shattered like a massive mirror.
Pure white fractures spread outward in crisscrossing lines across hundreds of meters of airspace.
A perfectly straight slash—its edges flickering with pale vibration arcs and dark-purple lightning—shot forward.
Silent.
Yet faster than thought.
"Pfft!"
The Blazing Roar Cannon shattered.
The slash pierced through.
There were no dazzling effects—only a distorted, blurred scar across vision itself, moving beyond the speed of cognition.
It cleaved through Napoleon and Big Mom's hastily raised arms.
It tore apart her defensive Haki.
It ripped through the "Iron Balloon" body that had withstood countless assaults.
Then—
Big Mom's enormous body froze.
Every movement halted.
The slash did not stop.
It continued upward—toward the sky itself.
The re-forming clouds were split in two.
All who looked up saw it—
The sky had been torn open.
A massive black fissure, its edges crackling with pale vibration arcs, was carved into the heavens.
It stretched across hundreds of meters.
And Big Mom—directly pierced by that Sky Rend—
fell like a severed kite, powerless, toward the shattered earth below.
Gern hovered beneath the fractured firmament, Bahuang still humming in his grasp.
His cold gaze followed Big Mom's descent.
Silence.
A deathly silence.
Only the temporary black scar across the sky—already beginning to mend—remained to testify in wordless awe…
to the might—
of Heavenquake.
