Hundredfold Iron Fist

Mary Geoise - Battlefield.

Flames, dust, seawater, and blood mingled to create a hellish scene.

"Roy--!"

Ace and Luffy's roars tore through the chaotic Battlefield!

In their eyes, there was Roy's figure, pierced by Imu's Shadow Arrow—

That arrow was born from the void, its black body shimmering with an abyss-like light.

It penetrates the air, penetrates space, and penetrates everyone's beliefs.

Blood flowed like a mist.

They rushed out almost simultaneously, only to be intercepted by the figures of two saints.

Despite being forced back into human form and covered in blood, Saint Mars and Saint Shepherd Ju Peter still roared and lunged at the two brothers.

"You won't get past me!"

Metal and flames clashed once more, causing the ground to collapse repeatedly!

Roy's body was pinned in mid-air, black energy churning from the wound in his abdomen.

The tail, formed from darkness, flicked gently, dragging Roy's body before Him like prey.

"Hiss..."

The air was sucked out, and black fog billowed.

Imu looked down at Roy, his Rinnegan eyes flashing with endless indifference and mockery.

Roy--

"You're quite an unexpected presence."

With a gentle flick of its tail, Roy's body was pulled closer.

Imu looked down at him, his expression indifferent yet tinged with a mocking pleasure.

"Although I don't know how that thing you prepared for your parents stored Conqueror's Haki..."

"But—" His lips curled up slightly,

My goal has been achieved.

"Ugh--!"

The tail stinger trembled violently, and dark energy surged into the wound.

An extremely cold force surged into Roy's body, accompanied by the intrusion of his "consciousness".

"This is... soul interference?!"

Roy's eyes narrowed, he gritted his teeth, and his inner lightning and armored Haki erupted simultaneously.

Imu leaned forward slightly, Rinnegan the patterns in his Rinnegan rapidly magnified in his pupils.

His voice echoed in Roy's mind, layer upon layer, as if he were speaking directly to his soul.

"This is 'Mu's' power—everything within you now belongs to me."

Roy gritted his teeth and swung his arm, the spatial blade rapidly slicing through the air, creating cracks in the air.

"Air Slash·Continuous Style!"

Countless spatial rifts tore open around Imu, a power capable of cleaving mountains and shattering the sky.

However--

Each strike, upon touching His body, seemed to pass through the surface of water, creating only silent ripples.

"It's no use," Imu said softly, swaying his tail slightly.

"You have entered the realm of 'M'."

The next second, the world lost its color.

All light, sound, and breath were extracted.

Darkness spread beneath my feet, swallowing the flames, the waves, and even the flow of time.

It was as if the world had shrunk to just the two of them.

You said you were ready?

Imu's voice became eerie and echoing, his silhouette transforming into a flowing shadow in the darkness.

"But in my opinion--"

"This is nothing more than history repeating itself!"

He opened his arms, and the entire void seemed to breathe in response.

"Black Turn - Domination!!"

A dark light swept over Roy like a tide.

Energy penetrates the body and reaches deep into the soul.

Black runes spread from his chest to his entire body, his pupils sunken, and his pupil color gradually swallowed up to pitch black.

"Ah--!"

Roy growled, and blood and lightning erupted simultaneously, the patterns on his body flashing with the clash of light and shadow.

It was as if two completely opposing wills were tearing him apart!

The air trembled, the ground shook, and even the boundaries of reality began to distort.

Imu's laughter was deep and satisfied. "Very good... that's it."

"A little more, a little more, until your will is completely swallowed by darkness--"

"Darkness, you will use your own hands to destroy this ocean!!"

However--

Just as Imu was about to completely shatter Roy's will, His smile froze.

The face shrouded in shadow trembled slightly.

"... wrong."

His Rinnegan suddenly contracted, and an unusual pulse spread from deep within Roy's chest.

That wasn't a fluctuation corrupted by darkness, but rather... a backlash.

Imu's breathing became slightly sluggish.

That feeling was both strange and familiar, a power that made His heart tremble.

"This... this is impossible--!"

He suddenly lowered his head.

All that could be seen was Roy's hand, which was tightly gripping His tail, emitting an eerie black light.

That light wasn't deathly darkness, but a living blackness.

Like an abyss breathing, it devours everything.

"You--"

Imu was about to speak when he saw Roy slowly raise his head.

Blood slid down his jaw, and his eyes flashed with a light that was a mixture of lightning and black flames.

Pain, sneer, arrogance—all converged in that instant.

"Oh..."

Do you think you're the only one who can control the darkness?

Imu's pupils trembled slightly.

That aura actually made His divine body feel uneasy for a moment.

What did you say?

I was just kidding!

Roy's lips curled up slightly, revealing a bloodstained yet extremely arrogant smile.

The next moment--

Darkness, spatial manipulation, and Haki —multiple forces erupted simultaneously within him!

"Buzz--!"

The heavens and earth suddenly collapsed!

Space was torn apart, and the dark realm instantly shattered into countless cracks.

Imu's body shuddered, feeling an irresistible force explode from within him!

His shadow form began to twist and break, as if forcibly expelled from His domain by some stronger "rule".

"This... this is--?!!"

"Return to the real world, Imu!!"

Roy roared, and the black light in his hand exploded completely!

"Boom--!"

In an instant, the black mist over Mary Geoise was completely blown away!

Imu's body emerged from the void, solidifying completely for the first time.

His expression changed abruptly amidst the intense energy Impact, from a cold laugh to shock, and then... fear.

"This is impossible... This is... human power?!"

He had just looked up--

What entered those eyes of Rinnegan was a golden-white light.

It was a fist.

A fist covered in thunder, shockwaves, and blood.

Behind that fist was a towering old man, his silver hair whipping back in the gale.

He was Teleportation to Imu by Roy, his fury blazing and his muscles bulging like mountains.

What followed was Thunderclap roar:

"Doubling - One Hundred Times Iron Fist!!"

A dazzling halo suddenly burst forth from his clenched fist!

Haki, shockwave, life force, and Armament Haki all overlapped in an instant.

Power Doubling —ten times, twenty times, fifty times... up to a hundred times!

--Punch!

Boom!!

The moment that punch struck Imu, the sounds of heaven and earth were silenced.

Only pure light.

Silent destruction is spreading.

The air was compressed into white light, Shockwave swept across the sky at the speed of light, Quake-Split the sea and the earth!

Quoting famous scenes

Looking down from space--

A cone-shaped gap was instantly torn open in the planet's clouds, and a golden-white Shockwave spread horizontally from the center of the Holy Land, engulfing half of the sky.

A fierce wind swept by, fire and thunder mingled, and humanity's Iron Fist finally tore apart the myth of the gods.
