Meanwhile, Akainu's figure shot toward Big Mom like a crimson lightning bolt.
His fists had already transformed into scorching magma, the intense heat distorting the surrounding air.
His eyes burned with cold killing intent, as if he wanted to completely devour the Yonko Big Mom before him.
"Hell Hound!"
Akainu growled, his right fist swinging violently.
Magma erupted from his fist like a volcanic explosion, forming a ferocious magma hound that opened its bloody maw and lunged straight for Big Mom's face.
This strike carried destructive power capable of burning everything to ashes.
Big Mom stood her ground.
Facing Akainu's attack, she didn't retreat but instead let out a wild, arrogant laugh.
"MAMAMAMA! Akainu, is this all you've got?"
Even as she spoke, Big Mom had already taken action.
Her Napoleon greatsword instantly became coated with dense Armament Haki, the blade gleaming with a dark light as lightning continuously crackled around it, seemingly capable of tearing through space itself.
"Emperor Sword: Heaven Splitter!"
Big Mom shouted, bringing her greatsword down with tremendous force.
The blade collided violently with Akainu's magma fist.
A deafening roar erupted!
Two terrifying forces collided in midair, with scorching magma and pitch-black domineering energy intertwining to form a massive vortex of power.
The sea surface churned violently from the colossal waves, causing the surrounding warships and pirate ships to rock uncontrollably under the force.
Akainu's brow furrowed tightly; he could sense the terrifying power behind Big Mom's strike.
This old hag has grown stronger again!
Katakuri's earlier transformation had already unsettled him, giving him a foreboding sense of dread.
He never expected it to be confirmed so quickly!
Big Mom must also be a dual- or even three-Devil Fruit user!
"Damn Whitebeard Pirates, damn that bastard Ron, you all deserve to die!"
Compared to Big Mom's Armament Haki, though he was evenly matched, her sheer physical strength was monstrous—he was being completely overpowered.
Despite his magma fists burning with intense heat, Big Mom's defensive capabilities were absurdly high; he couldn't even hurt this old hag!
"MAMAMA, Akainu, have you not eaten yet?!"
Another punch sent Akainu stumbling back several steps, the deck beneath his feet cracking under the strain.
"As expected of a Yonko," Akainu said coldly, the killing intent in his eyes growing more intense.
He lunged forward again, both fists swinging simultaneously, unleashing a torrent of magma like a downpour toward Big Mom.
Yet, she withstood it all, emerging almost completely unscathed!
Big Mom's laughter echoed across the sea, the very air hissing and vibrating.
Her body began to tremble slightly, the surrounding air twisting as if distorted by an invisible force, forming visible ripples.
Dark scales gradually surfaced on her skin, each one as hard as refined steel, gleaming with a cold metallic sheen.
"MAMAMAMA! Akainu, witness what a true power looks like!"
As she spoke, Big Mom's body rapidly expanded, her muscles bulging like mountains, bones cracking loudly.
Her arms transformed into massive dragon claws, sharp as blades and gleaming with a chilling light.
Her head began to change as well, sharp dragon horns sprouting from her temples, wreathed in dark Armament Haki as if capable of tearing through space itself.
Her eyes turned crimson, pupils burning with savage flames that seemed to devour everything in sight.
Her mouth parted slightly, revealing sharp fangs wreathed in black flames that emitted suffocating heat.
As her body continued to swell, a massive dragon tail extended from her back, its tip whipping through the air like a lash, capable of stirring up towering waves with a mere flick.
Her back became covered in dark scales, and black flame clouds billowed beneath her feet.
With a powerful surge, she whipped up a fierce gale, churning the sea into chaos.
Finally, Big Mom's body fully transformed into a colossal black dragon, coiling high above the sea!
Her body stretched hundreds of meters long, scales covering her like armor, dragon eyes burning with a crimson glow that seemed to pierce through all.
"Have you seen it? My Dragon form, the Black Dragon form! MAMAMAMA!"
Big Mom's voice roared from the dragon's mouth, filled with madness!
Her overwhelming strength made her disdain any need for concealment, for in the face of absolute power, all schemes and tricks were nothing but fragile illusions!
"…Kaido's Devil Fruit ability…" Akainu stood in the distance, his gaze fixed intently on Big Mom, a trace of gravity flashing in his eyes.
He knew that the Big Mom before him was no longer an ordinary Yonko but a terrifying existence that had fused with Kaido's Azure Dragon Fruit!
Her defense had reached a nearly invincible level, and her attacks were even more terrifying.
Now, even her recovery ability had...
"Black Dragon..." Akainu murmured softly, his fists clenching tighter, but his expression was as unpleasant as if he had swallowed a dead rat.
"Akainu, prepare to die!"
Big Mom's voice echoed from the dragon's mouth, filled with domineering authority.
Her dragon claw swept out violently, colliding with Akainu's magma fist.
With a thunderous roar, Akainu's body was sent flying backward, crashing heavily onto the deck.
But he quickly stood up, a trickle of blood seeping from the corner of his mouth.
"It seems I have to get serious."
Akainu muttered under his breath, his arms suddenly swelling, transforming into scorching magma sources billowing with thick smoke!
His fists resembled two volcanoes, magma flowing down his body, melting the surrounding deck into a crimson liquid.
"Great Eruption!"
Akainu roared, swinging both fists simultaneously as magma surged toward Big Mom like a tsunami.
The raging magma erupted like flames, gushing forth with a scorching, all-melting momentum!
"Is that all?"
A flicker of disdain passed through Big Mom's dragon eyes as her body coiled abruptly, spewing black-gold flames from her mouth!
"Heat Breath Shock!"
This was her "Dark Buddha Flame," born from the fusion of the Buddha Fruit ability, its flames containing the destructive power of a terrifying shockwave.
It clashed with Akainu's magma, erupting into a deafening roar.
The two forces deadlocked in mid-air, blazing magma and pitch-black flames intertwining to form a massive energy barrier.
The sea churned violently from the stirred-up waves, and the sky was dyed crimson by the fiery light.
