Naval Headquarters: "Everyone, be on high alert. That man... he's coming." Four Emperors: "Sh*t, who the hell provoked him this time?!" "Someone get ready to apologize. I’ll go in person if I have to..." The Dragon Hunting Pirates — a name that makes the entire world tremble!

[I’m combining every two original chapters into one for this fanfic. So if you see we’re at Chapter 200 here, that actually corresponds to around Chapter 400 in the original version.] Reborn as Brook—52 years before the events of One Piece—our protagonist defies fate, escaping from the depths of the Underworld to carve his own legend! Big Mom? Just a 16-year-old homeless pirate—recruit her! Whitebeard? Only 22 and still in a crew—bring him in! Redfield? The legendary loner—he's mine now! With his sights set on the future's strongest warriors, Brook sets sail to the Vodka Kingdom to find Kaido. If the next era is destined to be ruled by monsters, then he’ll make sure they sail under his flag! The Hell Pirates rise—dominating the Grand Line with power, ambition, and a crew destined to shake the world!

Ralph transmigrated into the world of One Piece. Right at the start, he was rescued by Luffy — only to discover, in shock, that Luffy had become a cute short-haired girl! Luffy… a girl?!!! Luffy had turned into Lufia — how was this adventure supposed to unfold now? She’s the granddaughter of a Marine vice admiral, the daughter of a revolutionary, and since childhood has been led astray by a certain red-haired pirate, dreaming of becoming the Pirate King. She’s optimistic, passionate, and full of dreams. Along the journey, regardless of gender, people are inspired by her, gathering around her as friends. In the end, everyone realises she is the Sun Goddess, destined to save the world! This… actually sounds pretty reasonable! After a kiss that sealed their bond (well — CPR), Ralph’s system awakens. His main quest: become the man of the Pirate King! As long as he gains characters’ affection, he earns rewards — the Six Powers, Haki, navigation skills… Gaining Lufia’s favor makes him grow even stronger. Become the Pirate King’s man, the partner of the Sun Goddess, and the ultimate reward will be granted! Big reward or not, it doesn’t really matter — like the One Piece itself, it might all be intangible anyway. What really matters is that I love girls with short hair, easygoing personalities, and serious foodie tendencies! I’m definitely going to become the Pirate King’s man! Sanji — I’ll compete with you in cooking! Zoro — I’ll compete with you in swordsmanship! Usopp — I’ll compete with you in bragging! Franky — I’ll compete with you in being outrageous! As long as it boosts Lufia’s affection, I’ll do anything! Robin — please don’t fall for me, my heart belongs only to Lufia! Hancock — you’re the worst offender, don’t think being beautiful is enough to—

After dying in his sleep, a modern-day anime fan isekai as a child, crewless Monkey D. Luffy. No crew. No Haki. No Gum-Gum fruit… yet. Just pain, awkward child limbs, and a system that turns life into a grindfest. Then the Partner System kicks in. To grow stronger, Luffy has to power up others first, because apparently being the main character wasn’t hard enough. Each buffed-up partner boosts his own stats and unlocks powers from across the anime multiverse. Fairy Tail magic? A one-hit kill blade? A soul-cutting sword that speaks? Absolutely. Now armed with grindable friendship, hellish Garp training, and a suspiciously game-like UI, Luffy’s ready to recruit his way to Pirate King. A dark, reimagined One Piece universe.

Akira Stone, possessing a Zanpakutō system, transmigrated into the One Piece world, using various Zanpakutō to defeat all powerful opponents! Forget fear, look bravely ahead. Move forward, don't stop, retreat only leads to decay, cowardice invites death. All Things in the Universe, Turn to Ashes, Ryūjin Jakka! All Ye Waves, Become My Shield. All Ye Thunder, Become My Blade, Sōgyo no Kotowari! Zangetsu!, Ryūjin Jakka!, Sōgyo no Kotowari!, Senbonzakura. Countless Zanpakutō are displayed in Akira Stone's hands. Akira Stone declares he has three dreams! “First, to become the world's strongest man; second, to marry the world's most beautiful woman; third, … …”

Adam died on Earth and woke up in the Naruto world. He doesn't have a "System," but he has two powerful gifts: the Light-Light Fruit (giving him the speed of light) and a Mask that gives him the sword skills of Roronoa Zoro. In the Konoha Academy, Adam pretends to be just a weak, average student. Nobody notices him. But when he puts on the mask, he changes completely. He becomes a terrifying villain who follows no rules. He strikes with light speed and fights like a demon. He is so dangerous that even the Akatsuki are afraid to attack him. Madara warns his team: "Stay away from this 'Zoro.' He is too strong and will ruin our plans." Pain is shocked when he faces him: "I am the God of Pain... but you act like the God of Death."

Reborn amid the salt, blood, and storm of the Iron Islands, a foreign soul awakens inside the body of Euron “Crow’s Eye” Greyjoy, long before madness and ruin claim his name. This time, however, Euron is no mere reaver driven by cruelty and chaos. He carries with him the Pirate King System, an otherworldly power born of legend and conquest. With his left hand, he unleashes Conqueror’s Haki, a kingly will capable of crushing weaker minds, bending lords to their knees, and tearing apart the intricate political webs of Westeros. With his right hand, he commands the Mastery of the Seas, ruling waves, storms, and fleets as if the oceans themselves answer his call—turning naval warfare into absolute dominion. This Euron knows the future. He knows the betrayals, the deaths, and the fate awaiting House Greyjoy. And he refuses to let his family be consumed by tragedy once more. As the Ironborn rise under a banner of discipline instead of madness, their ancient creed—“What is dead may never die”—takes on terrifying new meaning. From the Iron Islands to King’s Landing, from frozen northern waters to burning southern seas, Westeros is forced to face a truth it has never known: A true Pirate King has arrived. Balancing ambition with loyalty, brutality with vision, Euron sails not just to conquer—but to rule. When the waves finally break against the shores of the Seven Kingdoms, only one question will remain: Will the Iron Throne bend… or be drowned beneath the tide?

What if the legendary powers of the One Piece world were actually advanced Nen techniques? In this twisted reality, the "Iron Body" is Ken, and Observation Haki is En. When a fan with total knowledge of both worlds transmigrates into Chrollo Lucilfer, the balance of power shifts forever. With the Phantom Troupe at his back and a book capable of stealing thousands of Devil Fruit abilities, Chrollo enters the New World. The Worst Generation thinks they’re ruthless, but they’ve never met the Spiders. From the Five Elders to the mysterious Imu, no one is safe from the ultimate thief.

Saito transmigrated to a parallel world and joined the multiverse projection website. As long as he publishes edited videos on the site, he can obtain rewards.

NO. 8: Emiya Shirou Chops Off Gilgamesh's Arm! ...When these high-octane scenes were broadcast, various characters within the Omni-Anime World were shocked. “Sun Breathing?!

How could this King lose to a guy like that?!!” The chuunibyou Gilgamesh, who was relying on Mapo Tofu, was furious.

This story begins during the canon timeline, bridges world-breaking events, and continues past the series finale. Dracule Marya Zaleska has always lived in the shadow of her father, Dracule Mihawk, the world’s greatest swordsman. But Marya is no ordinary heir to a legendary name. Gifted with the enigmatic Oni-Oni no Mi (Mist-Mist Fruit), she wields the power to summon spectral apparitions and manipulate the veil between the living and the dead. Yet, this power is both a blessing and a curse, as it binds her to a destiny she does not yet understand. Determined to escape her father’s towering legacy, Marya sets out on a journey to uncover the truth about her mother, a woman shrouded in mystery who sacrificed herself to protect a secret so profound it could shake the foundations of the world. Along the way, Marya discovers fragments of her mother’s past—clues that lead her to ancient ruins, forgotten battles, and a conspiracy that ties her family to the origins of the Devil Fruits themselves. As Marya delves deeper into the mysteries of her lineage, she navigates treacherous seas, faces off against ruthless enemies, and uncovers the truth about the Mist-Mist Fruit’s dark origins. But the closer Marya gets to the truth, the more she realizes that her parents’ sacrifices were not just for her sake—they were to protect the world from a looming catastrophe. As the line between ally and enemy blurs, Marya must confront the darkness within herself and decide whether to embrace her Mist-Mist powers or reject them to forge her own path. "Dracule Marya Zaleska: Oni Phantom - Devil Fruit Origins" is a tale of legacy, sacrifice, and self-discovery. In a world where the past and present collide, Marya’s journey will reveal the secrets her parents died to protect and challenge her to rise above the shadows of her name to become a legend in her own right.

"Only Haki can reign supreme." That's the gospel according to Kaido. But I say he's dead wrong. Reborn into the One Piece world, I was given the [Fruit Encyclopedia]—a system that lets me analyze, copy, and collect every Devil Fruit ability I encounter. The best part? I'm not weak to the ocean or Seastone. While everyone else is training their Haki, I've already copied the Admirals' Logia powers and even Sengoku's Mythical Zoan. My only problem? Upgrading these powers costs a ton of Berries. To bide my time and build my arsenal, I've joined the Marines, hiding in plain sight as a "slacker" in the prisoner transport unit. They think I'm just a glorified delivery boy. They have no idea I'm cataloging the abilities of every legendary pirate I escort. Haki is supreme? I'll show them what a man with infinite Devil Fruits can do.
