For two long, grueling years, Cin sat in Impel Down's Level 6, surrounded by monsters, killers, and the worst criminals in history.
But he did not waste this time.
He trained. He evolved. He mastered everything.
Even with Seastone shackles, Cin pushed his body to adapt, developing ways to fight even under extreme limitations. He forced his Haki to new heights, clashed against the strongest prisoners, and became the apex predator of Level 6.
Now, his moment had finally come.
Race: Abyssal Predator – Apex Form

Threat Level: Beyond Yonko Commander
Haki Mastery:
Conqueror's Haki (Peak): Can split the sky with his will alone.Observation Haki (Future Sight): Can see several seconds ahead with perfect clarity.Armament Haki (Internal Destruction): Can bypass defenses and destroy enemies from within.

BOOOOOOM!
The entire prison shook violently as a massive explosion tore through the upper levels.
Alarms blared, prisoners screamed, and guards panicked.
Cin, sitting in the darkness of his cell, opened his glowing eyes and smirked.
"He's here."
Luffy, alongside Ivankov and Inazuma, was running through Level 6, searching for Ace's cell.
But instead, his eyes locked onto Cin, the towering predator chained in reinforced Seastone cuffs.
Luffy narrowed his eyes. "Who the hell are you?"
Cin chuckled. "I'm your way out of here."
Luffy frowned. "Tch! No time for distractions! I gotta find Ace!"
Cin leaned forward, his eyes glowing ominously. "I know exactly where Ace is."
Luffy hesitated.
Ivankov narrowed his eyes. "Straw Hat Boy, this guy... He's dangerous!"
Cin smirked. "Of course I am. But if you free me... I'll help you save your brother."
Luffy clenched his fists. He could feel the overwhelming aura coming from this being.
After a moment of thought, Luffy made his decision—
"Alright! Let's do this!"
Inazuma quickly sliced through Cin's restraints.
The moment the Seastone fell away, a monstrous wave of energy exploded outward, shaking the entire level.
Many weaker prisoners collapsed instantly, overwhelmed by Cin's Conqueror's Haki.
Ivankov's jaw dropped. "Oi, oi, what the hell is this guy!?"
Cin rolled his shoulders and cracked his neck. "Now then... let's cause some mayhem."
As they fought their way up, Magellan himself stood in their way, his Venom-Venom powers flooding the corridors with deadly poison.
Luffy gritted his teeth. "Tch! This guy again!?"
But before he could act—
Cin vanished.
BOOM!
In an instant, Magellan was sent crashing through three floors, his body twisted and mangled from a single attack.
Cin cracked his knuckles. "Pathetic."
Luffy's eyes widened. "Whoa! You took him down in one hit!?"
Ivankov stared in disbelief. "This is beyond anything I've ever seen..."
Cin simply smirked. "We're wasting time. Let's go."
As the group raced toward the exit, they were suddenly stopped by something unnatural.
The ocean itself... was freezing solid.
A massive wall of ice blocked their escape, stretching as far as the eye could see.
Luffy's eyes widened. "This is...!"
Cin narrowed his eyes. "Kuzan."
Aokiji stood atop the frozen sea, arms crossed, his usual calm expression unshaken.
"You should've stayed locked up, beast."
Luffy gritted his teeth. "Damn it! We don't have time for this!"
Cin exhaled. "Leave him to me."
Before Aokiji could act, Cin grabbed Luffy and hurled him over the ice wall, sending him flying toward the waiting ship.
Luffy screamed, "WHOAAAAA!?!?" before safely landing on the escaping vessel.
Ivankov and Inazuma followed suit, barely escaping before Aokiji could react.
Cin, standing alone, smirked. "See you at Marineford."
Then, with a flash step, he vanished into the frozen wasteland—escaping before Aokiji could stop him.
The war at Marineford was already a nightmare.
Whitebeard vs. The Marines.
Luffy charging in to save Ace.
Yonko Commanders battling Admirals.
But nothing—nothing—prepared them for Cin.
A monster beyond anything this world had ever seen.
As the war raged, Cin descended onto the battlefield like a demon.
Kizaru, Aokiji, and Akainu stood side by side, realizing that this single being was a bigger threat than Whitebeard himself.
Akainu sneered. "You're a fool for coming here, monster."
Cin smirked, his Conqueror's Haki cracking the very air. "And you're about to die, lava dog."
The Battle Begins
BOOM!
The moment Cin moved, the entire battlefield shook violently.
Aokiji launched massive icebergs.Kizaru fired light-speed laser barrages.Akainu created an entire tsunami of magma, aiming to incinerate Cin completely.
But it wasn't enough.
Cin vanished—dodging Kizaru's lasers before they even fired.
He appeared behind Aokiji, his fist coated in Internal Destruction Haki, and PUNCHED STRAIGHT THROUGH THE ADMIRAL'S CHEST!
"GAHHH!!" Aokiji coughed blood, crashing into the battlefield.
Before Akainu could react, Cin grabbed his face and SLAMMED him into the ground—shattering Marineford beneath them!
Akainu, enraged, erupted with magma, burning everything around him.
"I WON'T LOSE TO A MONSTER LIKE YOU!!"
Cin chuckled. "You already have."
BOOOOM!
Cin PIERCED THROUGH AKAINU'S CHEST, ripping his heart out in one swift move.
The entire battlefield went silent.
Then Cin devoured him.
The moment he ate Akainu, his body twisted, transformed, and evolved once again.
Haki Ascended:
Conqueror's Haki – Tyrant's Will: Can now crush weaker foes instantly.Observation Haki – Absolute Sight: Can predict attacks minutes ahead.Armament Haki – Black Abyss: Coating so strong it melts through defenses.
Devil Fruit Absorption:
Mag-Mag Fruit (Magu Magu no Mi) Absorbed.Now fused with his body, making him a living magma beast.
Physical Enhancements:
Now completely immune to fire, heat, and lava.Body density increased—strikes from even Garp won't fully break him.
Sengoku's voice roared across Marineford.
"ALL FORCES—ATTACK CIN NOW!!"
In a fit of rage and desperation, Sengoku, Garp, Aokiji, and Kizaru all charged at once.
Garp's RageTears of fury burned in his eyes."YOU KILLED AKAINU, YOU MONSTER!"He punched with enough force to shatter islands.Sengoku's WrathHe transformed into his Buddha form, unleashing golden shockwaves that obliterated entire fleets.Aokiji & Kizaru's DesperationAokiji, injured, tried freezing Cin completely.Kizaru unleashed a barrage of light beams, hoping to burn him away.
But Cin simply grinned.
"Come then. Let's see if you can stop me."
The battlefield was already drenched in blood.
Marineford shook under the weight of monsters clashing.
But no one—no one—expected what happened next.
Garp's fists shattered the ground.
Sengoku's golden shockwaves cracked the air.
Aokiji's ice turned the battlefield into a frozen wasteland.
Kizaru's lasers rained down like a divine purge.
But Cin stood tall.
Bruised. Bloodied. But undefeated.
He grinned. "You're all still standing? That's impressive."
But deep inside, he knew—this fight could drag on too long.
That's when he saw it—Luffy and Ace escaping.
Then it hit him. An idea.
A risky, monstrous, and utterly insane idea.
"If I help the Marines... I can eat Ace."
Luffy ran, dragging Ace with him toward the last escape ship.
Tears still stained his face.
Then—Cin moved.
BOOM!
In a flash, he appeared behind Luffy, his claws coated in Armament Haki.
Luffy barely turned, his eyes wide.
"Cin?! What are you—"
SLASH!
A blur of motion.
A spray of red.
Ace gasped. His body froze.
Cin's claws pierced straight through Ace's chest.
Silence.
Then—a scream.
"ACE!!!!!!"
Luffy's voice cracked as he watched his brother die right in front of him.
The battlefield stopped.
Whitebeard's crew froze in horror.
The Marines—even the Admirals—were speechless.
Cin had done what even Akainu failed to do.
He killed Ace.
And then, before anyone could react—he devoured him.
Cin's body convulsed.
His veins burned as an explosion of power erupted from within.
He had consumed a being carrying the Will of D.
Something no one had ever done before.
His Haki surged to levels beyond even Whitebeard's.
New Power Gained:Conqueror's Haki – Supreme Tyranny → Can now crush even Admirals just by looking at them.Flame-Flame Fruit (Mera Mera no Mi)
Luffy collapsed, his screams of agony cut short as his body hit the ground.
Tears still rolled down his cheeks, but he was unconscious—his mind shattered from the loss.
Silence.
Then—an explosion of rage.
"CIN!!!"
Whitebeard's entire crew lunged at him, their fury turning into an unstoppable wave of vengeance.
Even the Marines—who once hated the pirates—stood beside them.
At that moment, Cin was no longer just an enemy.
He was a threat to the world itself.
With Ace's flames merging into his own power, Cin's body pulsed with a new, horrifying might.
[Cin's Status After Consuming Ace]Conqueror's Haki (Supreme Tyranny) – So powerful that even the strongest warriors struggle to stand.Observation Haki (Divine Foresight) – Can see seconds into the future like Katakuri.Armament Haki (Black Inferno) – His body is now so tough that even Whitebeard's spear barely cuts him.Flame-Flame Fruit (Awakened) – Can turn the battlefield into an inferno at will.
Cin stood there, unmoving.
Then, he grinned.
"Finally... you all recognize me as a true threat."
Whitebeard – "For my son... I WILL END YOU!" He swings his quake-infused naginata straight at Cin's head.
🔹 Garp – Tears fall from his eyes, but he moves anyway. "I should've done this earlier, you bastard!"
🔹 Sengoku – Golden Buddha form shines, his palm crashing down like judgment itself.
🔹 Kizaru, Aokiji, and the remaining Marines – All launch their strongest attacks.
The sky cracks.
The ocean rages.
The island itself begins to sink.
Cin, standing at the center, laughs.
The battlefield was drenched in chaos.
Marines and pirates alike lay scattered, bodies burnt, frozen, or crushed under the sheer power of the clashing titans.
At the center of it all—Cin stood victorious.
Whitebeard's breath was ragged. Blood trickled from his mouth as he staggered back, his once-unshakable strength wavering.
🔹 His body was scarred, a deep claw mark tearing across his chest, flames still burning through his wounds.
🔹 He clutched his naginata, but his hands trembled. His legendary endurance, the very thing that made him the strongest man alive, was finally breaking down.
Cin tilted his head.
"This is it? This is the power of the man they called a 'monster'?"
BOOM!
In an instant, Cin vanished—reappearing behind Whitebeard with his claws coated in blackened flames.
"Die, Whitebeard."
SLASH!
A deep gash tore through Whitebeard's back, and for the first time in decades—he let out a cry of pain.
The pirates froze.
Their father—their captain—was losing.
Even as his vision blurred, Whitebeard refused to fall.
His Conqueror's Haki burst outward, shaking the very heavens.
"I am Whitebeard!" he roared, slamming his foot down, his quake powers erupting in full force.
The island itself split apart—even Cin was forced back, sliding across the battlefield.
🔹 But Whitebeard knew... he didn't have much time left.
🔹 His crew was watching. His sons needed to escape.
Even if it meant his own death—he would not let Cin stand as the final victor.
Sengoku's fists clenched.
🔹 Garp's face darkened, his heart heavy with guilt.
🔹 Kizaru and Aokiji prepared to step in—but even they felt a shiver of fear.
No one... had ever done this to Whitebeard before.
And Cin... wasn't even done evolving yet.
"Come then, old man," Cin smirked, flames wrapping around his body like a demonic god. "Let's end this."
As Whitebeard lunged forward, his quake-infused naginata swinging toward Cin's head—
Something happened.
A pulse.
A shift in reality.
Cin's entire body shuddered, his eyes widening as an unimaginable power surged through him.
His Observation, Armament, and Conqueror's Haki—
They merged.
They twisted, fused, and transformed into something new.
Something beyond haki itself.
The skies darkened.
The sea trembled.
The very heavens recoiled in fear.
🔹 Whitebeard's strike—halted in midair. Not because Cin blocked it, but because an invisible force crushed the attack before it could even reach him.
🔹 The ground ripped apart, creating a chasm so deep, it looked endless.
🔹 The air itself vibrated, carrying a silent scream of the universe as if reality itself was rejecting Cin's existence.
"What... is this?" Whitebeard's voice was barely above a whisper, his grip tightening on his weapon.
Cin lifted his hand, his claws coated in a darkness deeper than anything before.
"This..." he muttered, feeling the energy in his veins, "is something this world has never seen before."
With a single step, he vanished.
The battlefield stood still, locked in silent horror.
The legendary Whitebeard, a man whose very presence shook the world, now stood before something beyond comprehension. Cin had become an entity that even the heavens feared. His new power—no longer just haki—radiated from him like a force of nature, warping the very fabric of the world itself.
Then, he moved.
It wasn't speed. It wasn't teleportation. It was something else entirely. One moment, he was standing there. The next, he was behind Whitebeard.
A sickening crack echoed as a shockwave erupted from Whitebeard's back. Blood spewed from his mouth as his body jerked forward unnaturally. The strongest man in the world had never felt an impact like this before.
Yet, he did not fall.
Whitebeard, ever the warrior, spun around with a guttural roar, his naginata coated with the full force of his Tremor-Tremor Fruit. He swung with all his might, the air itself fracturing from the devastating quake force.
But Cin didn't move.
He didn't block.
He didn't even acknowledge the attack.
The moment the weapon was supposed to connect, the space between them shattered, twisting reality itself. The tremor force dispersed into nothingness, as if it had never existed in the first place.
Whitebeard's eyes widened. "Impossible... What have you become?"
Cin gazed down at his own hands, flexing his fingers, feeling the sheer weight of his own power. This wasn't just haki anymore. It was something more. Something primal. Something cosmic.
And then he looked back at Whitebeard, a slow grin spreading across his face. "I have become what this world has always feared but never knew existed."
A black shockwave exploded outward as Cin raised his hand, forming a claw-like shape. The very air around him became heavier, pressing down on everything in sight. Marines watching from afar collapsed instantly, their eyes rolling back, foaming at the mouth from the sheer pressure.
Even the other Admirals, Garp, and Sengoku—some of the strongest warriors alive—felt their legs trembling.
"This is beyond Conqueror's Haki..." Sengoku muttered, sweat dripping down his face. "No... This is beyond haki itself. It's something else entirely."
Whitebeard knew he couldn't hold back anymore. His body ached. His lifespan had already been whittled down by his injuries. But none of it mattered.
With an earth-shattering roar, he mustered all the power in his body. The sky cracked. The sea split. The very foundations of Marineford threatened to collapse.
"GUURAAGH!!" Whitebeard unleashed a final, full-powered strike aimed directly at Cin's heart.
Cin simply sighed.
Then, with nothing but a flick of his wrist, he canceled the attack.
The entire battlefield shook violently as Whitebeard's attack was swallowed whole. His ultimate move, an attack that could have split an island in half, was erased as if it were nothing more than a passing breeze.
For the first time, Whitebeard felt fear.
Cin didn't hesitate. In the blink of an eye, he was in front of Whitebeard, claws piercing through his chest.
A gasp escaped the legendary pirate's lips as his vision blurred. He could feel it—his very life being drained away.
Cin leaned in close, whispering, "The age of pirates? It ends with me."
With a final, monstrous burst of power, Cin ripped Whitebeard apart.
The world seemed to stop.
Silence.
Then, chaos.
Screams erupted across Marineford. The Whitebeard Pirates, witnessing their captain's brutal death, charged at Cin in a desperate frenzy. But it was useless. He moved like a phantom, slicing through them with horrifying efficiency. Each strike carried not just raw power but an erasing force that shattered the essence of their very beings.
Garp clenched his fists so tightly they bled. "That's enough."
He vanished in an instant, reappearing in front of Cin with a fist coated in the purest, most refined Armament Haki ever seen. It was an attack fueled by rage, sorrow, and duty. An attack meant to end the madness.
Cin smirked. "Try it."
The moment Garp's fist made contact—
The world broke.
A massive explosion of energy engulfed the battlefield. Mountains trembled. The ocean raged. Even the distant islands felt the shockwave.
When the dust settled, Garp stood there, panting heavily, his fist still against Cin's chest.
Cin looked down at where Garp had struck him.
There was nothing.
No wound. No damage. Nothing.
Then he grinned.
"Nice try, old man."
With a brutal counter, Cin grabbed Garp by the face and slammed him into the ground, creating a crater large enough to swallow an entire battleship.
Sengoku, Kizaru, and Aokiji rushed in next, each attacking from different angles. But it was pointless.
Cin was no longer fighting on their level. He was above them. Far above them.
And he knew it.
Marineford, the center of the world's greatest war, had turned into a slaughterhouse.
The battlefield stood still. The moment Cin's Haki merged into one—Conqueror's, Armament, and Observation intertwining into a single, devastating force—the very heavens above Marineford seemed to crack. Lightning of a deep crimson hue rippled through the sky, storms brewed without warning, and the sea trembled under his presence.
Everyone could feel it. Something beyond comprehension had just been born.
Whitebeard, the legendary "Strongest Man in the World," coughed up blood as he staggered. His injuries were severe, but his will remained unshaken. However, Cin was different now. He wasn't just a threat to the battlefield—he was a threat to the entire world.
With a single step, Cin appeared before Whitebeard, claws coated in the unknown fusion of his Haki. The old man barely had time to react before Cin pierced through his chest, gripping his heart with a monstrous grasp.
"Old man... your time is over."
Whitebeard's eyes widened as his strength faltered. The moment Cin devoured him, his entire body pulsed with a new, terrifying energy. The power of the Gura Gura no Mi—the fruit that could shake the very world—was now his.
The Marines and Pirates alike froze in horror.
Sengoku, still in his golden Buddha form, shouted in rage, "Cin! You monster! We cannot allow you to exist!"
But before anyone could strike, Cin vanished and reappeared before Garp. The old Marine legend barely had time to clench his fists before Cin's claws ripped through his torso.
Garp's eyes, once full of determination, dulled. The moment he collapsed, Cin absorbed him as well.
A tidal wave of new power surged through his being.
Cin's body shifted once more. His muscles became more defined, his skin darker, and his entire aura took on an abyssal shade of black with streaks of red lightning. His Haki—no, his very existence—became something beyond mere mortals.
The world stood no chance now.
"ENOUGH."
Suddenly, a force unlike any other descended upon Cin.
The entire universe rejected him.
A massive, golden portal tore open above him, its light blinding and divine. The very laws of reality twisted as the world itself sought to correct the overwhelming imbalance Cin had created.
"You do not belong here."
It was as if the universe itself was speaking.
Cin growled as his feet began to lift off the ground against his will. He resisted, digging his claws into the fabric of space itself, but it was futile. The cosmos had deemed him a threat beyond comprehension.
As he was sucked into the portal, the last thing he saw was Marineford, completely decimated, and the faces of warriors who now feared him more than they ever feared death.
Then, all went white
Cin stood motionless, his body tense as the winds of this unfamiliar world howled around him. The sheer pressure radiating from the three warriors before him—Goku, Vegeta, and Jiren—was beyond anything he had ever felt.
In the One Piece world, he was a god. But here...
Cin took a cautious step forward, clenching his fists as he tried to gauge his own strength. He could feel the power of the Gura Gura no Mi, the devastating Haki he had mastered, and the abilities he absorbed from Whitebeard, Akainu, and even Garp.
But when he focused... he felt nothing.
"What the hell...?" he muttered.
Something was wrong. The overwhelming strength he once had—the power that crushed Marine admirals and shook the seas—felt distant, like a fading memory.
Then, a voice echoed from behind.
"Huh? Who's this guy?"
Cin turned sharply, his instincts flaring, only to see a short, bald man in an orange gi.
Krillin.
Despite his small stature, the mere presence of this warrior made Cin's stomach drop. There was no killing intent, no Haki, no grand presence—yet Krillin felt stronger than him.
The realization hit like a freight train.
"No... way."
He took a step back, his legs suddenly weak. This was just a human. In his world, Cin had long surpassed humanity, becoming a monster that defied even reality itself. Yet here he was, standing before a human who could erase him with a single punch.
Krillin scratched his head. "You okay, dude? You look like you just saw a ghost."
Cin didn't respond. His pride was shattering.
His breath grew ragged. His Haki wasn't responding. His Devil Fruit abilities were silent. His strength, speed, endurance—all of it was gone.
It was like the very laws of this universe denied his existence.
Goku landed next to Krillin, giving Cin a curious look. "Huh. Never sensed a guy like you before. But... uh..." He rubbed his chin. "You don't seem that strong, to be honest."
Cin's eye twitched.
Vegeta scoffed, crossing his arms. "What a waste of time. If this is the 'great threat' Whis mentioned, I'd rather go train in the gravity chamber."
Jiren, who had been silent the entire time, simply turned away. He didn't even acknowledge Cin as a fighter.
That was the worst blow of all.
Cin gritted his teeth. He wanted to scream, to lash out—to prove that he was still the apex predator. But no matter how hard he tried to summon his strength, it just wasn't there.
The reality was clear.
He was nothing in this universe.
Then, the skies above rippled. A divine voice called out.
"Now that you understand... you may begin again."
Before Cin could even react, his body dissolved into light—his very essence breaking apart, as if rewritten from existence.
The last thing he heard was Beerus chuckling.
"Pathetic."
Then, everything went dark.
Darkness. Cold, infinite nothingness.
Cin's consciousness floated aimlessly, his mind fractured by the sheer weight of defeat. He had dominated one universe, crushed legends beneath his feet, only to be erased like an insect in another.
But something refused to let him fade.
[Rebooting...]
A strange, robotic voice echoed through his very soul.
[Simulation System Engaged]
A blinding flash consumed him. The next thing he knew... he was alive.
Cin gasped, his lungs burning as if he had been suffocating for centuries. He shot up, his body trembling. He looked down at his hands. They were his hands.
Not the monstrous, evolved form he had taken before—no demonic claws, no overwhelming presence—just him. His original body, back to square one.
He took a deep breath, his surroundings becoming clear. He wasn't in a void. He was in a vast, empty wasteland. Purple skies loomed above, and strange, alien structures dotted the horizon.
"Where... am I?"
Then, it hit him.
This wasn't the same Dragon Ball universe he had been erased from. It was a different one. A different timeline.
And this time, he was weak again.
[New Host Detected]
[Reactivating Simulation Mode]
Cin's vision flickered. A strange interface materialized in his mind—his system had returned.
[World Detected: Dragon Ball Timeline #??]
[Host Power Level: 5]
Cin nearly choked.
Power Level: 5?!
He clenched his fists, shaking in rage. He had once fought gods, shattered continents, killed emperors... and now he was weaker than a damn farmer?!
"No." His teeth ground together. "I refuse."
[Simulation Mode Activated]
Suddenly, a new prompt appeared.
[Select a Simulation Training Mode]
1️⃣ Saiyan Evolution – Train as a Saiyan from birth, adapt their limitless growth potential.
2️⃣ Haki Refinement – Regain lost Haki mastery, upgrade to divine levels.
3️⃣ Zenkai Survival Mode – Fight in life-or-death scenarios repeatedly to force power jumps.
4️⃣ Legendary Bloodline Fusion – Unlock new races through extreme simulations.
Cin's mind raced.
This was his chance. The system hadn't abandoned him. It was forcing him to evolve the right way.
"Fine. If this world thinks I'm weak, then I'll break its limits too."
He selected all four options.
[Simulation Starting... Survive or Die.]
The world around him shattered.
And Cin's true evolution began.
