Thirty-eight years ago, the God Valley Incident was brought to an end by the World Government, marking the curtain fall of the Rocks Pirates. However, the Celestial Dragons, lofty as they were, failed to realize that an even more terrifying monster had begun to move. Soon, his enemies would discover that no matter how many times they severed his head, pierced his body, or reduced him to ashes—none of it could truly kill him. Only when blood flooded the vacant throne did they finally understand who their opponent truly was. The man who pushed the Bat-Bat Fruit, Mythical Zoan, Model: Vampire, to an unprecedented level. The man whose mastery over all three colors of Haki reached its absolute peak. His name—Nereus. Lord of the Deep Seas, Immortal King, the Liberator… His name has never ceased to echo across the seas.

My name is Chad Cain, a transmigrator, Luffy's third older brother and just an ordinary pink-haired teenager. I used to have a cushy Marine job, thanks to my grandfather-grandson relationship with Garp, I could have easily coasted like Kizaru, punching in and out while working a desk job as a low-ranking clerk. But everything changed when I took Garp to that island and ate that fruit. Where did this ridiculous rumor even come from? What's this about me being the illegitimate child of two Emperors, Kaido and Big Mom? PS : A single pairing with Uta and mc will supposedly act as a 'spy' later in luffy ship.

In the Great Pirate Era, countless people rushed to the sea. The person who obtained Arceus’ power arrived in this world as the new Arceus and got in touch with the Lunarian race. Based on the reality that everything can be Mythical Zoan, the current him can also be called Mythical Zoan user. Whether it is One Piece or Pirate King, it has nothing to do with him, all he wants to do is to retrieve the lost plates first. During this process, he formed an alliance with Beasts Pirates, a famous pirate crew in the New World, and Mr. Kaido got his coveted Mythical Zoan Army. When Pteranodon becomes Aerodactyl, when Brachiosaurus becomes Tropius, the combination of Pokémon and devil fruit powers will bring a whole new change to the world…. Lunarian’s glory will surely reappear. *This is a fan translated novel by me ****Please support on pat*eon for extra chapters https://www.pat*eon.com/dmtranslations

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?

No system + Celestial Dragon + Sharingan + Mythical Zoan + Scholar + Roger Pirates ... Year 1 after joining the Roger Pirates Valthior: “Can you guys stop being so violent? I’m just a scholar—I can’t even tie up a chicken!” ... Year 5 after joining the Roger Pirates Valthior: “Hey, slow down with the killing! Leave one for me—I just learned a new move. I wanna split his damn head open!” ... Year 10 after joining the Roger Pirates Valthior: “Captain, why are you wasting time talking to him? I’m gonna chop him into a bloody mist!” ... After reaching Laugh Tale and uncovering the secrets of history Valthior: “This is just the end of the journey—not the peak! Why are we disbanding? I’m the most educated one on this ship, so listen to me—first we take down Shiki, then we smash Whitebeard! We’ve gotta truly live up to the name of Pirate King!” ... Twenty years later Valthior: “As the saying goes, the student surpasses the master. My captain became the Pirate King—so if I don’t become the King of the World, wouldn’t that make this life a waste?” ... Alternate name: One Piece: I Only Learned Killing Was Illegal

"At a high-level review meeting for the Naval Inspection Department, a stern official glares at the East Blue's newest inspector, Lancelot. ''Inspector Lancelot, explain this!'' the official demands. ''Why do seven different queens from kingdoms across the East Blue have children who bear a... striking, 70-to-80-percent resemblance to you?'' Lancelot, busy admiring a secretary, just yawns. ''Coincidence.'' ''Coincidence?!'' ''Absolutely,'' Lancelot says, pointing a thumb at the furious Fleet Admiral. ''I mean, I share a good 60-percent resemblance to Admiral Akainu. Does that mean he's my long-lost son?'' An explosion of magma vaporizes the corner of the table. ''I'VE HAD ENOUGH OF THIS PUNK!'' ''Ooh, scary~'' Kizaru drawls, holding him back. ''Just endure it a little longer, Sakazuki...'' ''You can't beat him, anyway,'' Aokiji mutters from under his sleep mask. ''Then explain this!'' the official snaps, moving on. ''Why do your East Blue marines receive salaries and benefits that rival Headquarters?'' Lancelot scoffs. ''With the original paltry pay, you could barely scrape by. Why would anyone choose this job over being, say, a pirate? I'm just making the job competitive!'' This is the story of Lancelot. After transmigrating into the body of a 3-meter-tall, famously weak, and cowardly Marine nepo baby, he decides to flip the script. Armed with a corrupt Vice Admiral father in Mariejois, two overpowered Systems, and a complete lack of shame, Lancelot's journey is just beginning. His plan? Con an OP swordswoman into joining him (and giving her a Zoan fruit), recruit a 12-million-Beri pirate as his enforcer, and fake being an 'Absolute Justice' psycho. Lancelot is out to build an empire, get filthy rich, and assemble a 'team' of the most beautiful women in the seas... all while pretending to be the most terrifyingly efficient Marine in the East Blue."

Fate tried to kill Ace. I said no. In the heart of the greatest war in history, a fourth brother stepped out of the shadows. With the world watching, the brothers did the impossible—they survived. Now, the seas are no longer ruled by the old guard. From the "War God" Dragon Soul to the "Bright King" Luffy, the four brothers have ascended. No more running. No more losing. The Navy is in retreat, the World Government is in a panic, and the Four Emperors' throne has new masters. This is their sea. This is their era.

"I raised the Hero of the Marines, mentored the Fleet Admiral, and shaped the era itself. Now, at a hundred years old... my journey is finally beginning." Transmigrating into the world of One Piece with a personal System, Rowan expected to reach the pinnacle of power in record time. But fate had other plans—the System glitched, remaining stuck in a loading loop for decades. Rowan didn't wait around for a miracle. Using his knowledge of the future, he carved his own path. He adopted a rowdy brat named Monkey D. Garp, forged a life-and-death brotherhood with future Commander-in-Chief Sora, and disciplined a generation of legends including Sengoku, Zephyr, and Tsuru. A century has passed. While training his great-grandson, Luffy, Rowan finally feels the heavy toll of time on his bones. Just as he prepares to close his eyes and accept the end of his long watch, a familiar sound echoes in his mind: [System Loading: 100%... Activation Successful.] [First Mission: Become a Marine Admiral.] Looking at the prompt, the century-old legend can only scoff: "Are you kidding me? I’ve been the backbone of the Navy for a hundred years, and now you want me to start a career as an Admiral?!" The Old Guard has returned. The pirates think the era belongs to them—until they meet the man who raised their greatest enemies.

Cyrus wakes up in the brutal world of One Piece—and finds the legendary Mera Mera no Mi right in front of him. Eat it and gain unimaginable power… or leave it and die?

Cyrus sets his sights on Shimotsuki Village, the legendary home of master swordsmen, to train under the finest sword instructor in east blue. There, he fuses the scorching might of the Flame-Flame Fruit with razor-sharp swordsmanship, forging an entirely new style: Fire style Swordsmanship—a blazing fusion of fire and steel that leaves nothing but ashes in its wake. A transmigrator armed with fire, sword, system, and sheer audacity—watch Cyrus burn his way across the Grand Line, rewriting what it means to be a swordsman… and maybe the entire pirate era along with it.

[A/N: This work seems like the copy of the work. one piece : The ship of lust. And yes while writing I have copied some of the elements. It is easy to write in exciting ground work as I am new to writing. Well if I am writing the r-18 work then it is best to take some from my favourite work which had inspired me to write. But do not worry the work is totally diverted from chapter 15. There may be similarities because of system and because they are fanfic of same anime. But I assure it is totally different fanfriction and you will enjoy it.] Also please visit my patreon for advance chapters along with arts and picture collection in manga style.

Ren was transmigrated into a Mythical Zoan-Type Devil Fruit. Before his consciousness was completely devoured by the demonic will of the Yamata no Orochi Fruit, Ren awakened the Satan Soul, a form of Reception Magic from Fairy Tail that allows one to receive demons. Ren realized that Devil Fruits themselves are a kind of demon. By forcibly receiving the Yamata no Orochi Fruit, he seized control of its demonic consciousness and rose to rule Wano Country. “Wano Country? That name is awful. From now on, this country will be called Inazuma!” … Forty years later, when Roronoa Zoro stood before Hawkeye, his body covered in wounds, he could not help but speak: “A man like you is not the world’s greatest swordsman…” “You frog in the well—have you ever heard of the One-Cut Wonder technique?”

Reborn in the Goa Kingdom. Alongside his new life comes a mysterious Pokémon System, granting him various abilities never seen before in the world of One Piece. With no Devil Fruit to rely on, no legendary bloodline, and no powerful family backing him, he must survive using only his previous Pokémon knowledge. As pirates chase freedom, marines pursue justice, and the World Government guards secrets buried for centuries, a new force quietly begins to rise. Will his strange powers be enough to carve out his own legend, or will the Grand Line swallow yet another dream before it can truly begin?

I, Natsuki, was reborn in Konoha as a classmate of Kushina Uzumaki. My start was ordinary, but my destiny was not. A system awakened within me, offering me the world on a silver platter. My cheat? A [Gacha Template System] that allows me to draw and fuse with character templates from across the multiverse. With every pull, I became someone new, someone stronger. One pull gave me the deductive genius of Conan Edogawa. Another granted me the boundless potential of Monkey D. Luffy. A lucky draw bestowed upon me the god-like power of Gojo Satoru. And a legendary pull blessed me with the transcendent cunning of Aizen Sōsuke. As these legendary templates merged into one being, the Shinobi World finally met its new, undisputed ruler.

I, Zenji, woke up in the middle of a battlefield during the Third Great Ninja War. My only cheats? A complete knowledge of Jujutsu Kaisen burned into my mind, and two soul-bound treasures. I soon discovered a fatal flaw: for my Earth body, refining chakra was a slow form of suicide. But I just smiled. With Reverse Cursed Technique for self-healing and the Incarnation secret art to switch bodies, I possessed something that even Orochimaru would kill for. Using my knowledge, I created two ultimate trump cards: a "Gojo Satoru" with his Six Eyes bloodline and localized Limitless technique, and a "Sukuna" with a Wind and Fire Style Malevolent Shrine. The Hyuga clan claimed my Six Eyes was a stolen bloodline? I let 'Gojo' handle them. It didn't take long. My ultimate goal is not just to survive. I will use my treasures to re-establish the power of Jujutsu in this world, creating a new branch of power rivaling chakra itself. And my final target? The Chakra Fruit of the Ōtsutsuki!

Waking up in the Grand Line with a Reputation System, Ryuuto gains the power to command the weather itself. Rain becomes his blade, wind his weapon, and lightning his judgment.

Ben ends up in One Piece world with template system. First 8 chapters the narration is not so good after that it will be ok. --- Disclaimer: I don't own any of the characters or the songs used in this fic.

Thirty-eight years ago, the World Government put an end to the God Valley Incident, and the curtain fell on the era of the Rocks Pirates. However, the high and mighty Celestial Dragons did not realize that an even more terrifying monster had begun to make his move. Soon enough, his enemies realized the grim truth: beheading him, piercing his body, or even reducing him to flying ash... none of these methods could truly kill him. It was not until blood drowned the Empty Throne that they finally understood exactly who their opponent was. He is the man who developed the Bat-Bat Fruit, Mythical Zoan Model: Vampire to an unprecedented level. He is the man who honed all Three Types of Haki to the absolute peak. His name is Nereus. Lord of the Deep Sea, The Undying King, The Liberator... The legends regarding his titles have never ceased to echo across the seas...

"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.
