"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.

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.

By the will of the gods, or perhaps their mistake, Zorn was thrown into the world of Fairy Tail. Blessed with the power of light itself, he awakened the abilities of the Pirate Admiral Kizaru, absolute speed, overwhelming attacks, and an untouchable body of light. On top of that, Zorn mastered Holy Light Magic, a sacred force feared by demons and dark mages alike. Rising at an unbelievable pace, he became the youngest S Class wizard in history and soon claimed a seat among the Ten Wizard Saints. In a world ruled by magic, Zorn walks the path of pure light, not as a hero, but as a domineering pioneer who stands at the forefront of a new era. ---------------------- Advanced chapters at p@treon

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.

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.

In a world where genetic Quirks define a hero’s worth, Roronoa Zoro stands as a silent defiance against the status quo. Born Quirkless within the walls of a traditional dojo, he trades flashy innate powers for the grueling, rhythmic grind of the blade, pushing human limits through thousands of daily swings and unwavering discipline. As he sets his sights on the prestigious U.A. High alongside Midoriya’s generation, Zoro’s journey is a meticulous, slow-burn chronicle of sweat and steel, proving that a sharpened spirit and a master’s technique can cut through any biological advantage.

An ordinary guy from Earth is reborn in the world of One Piece with three advantages, one of them powerful enough to change history. The seas are brutal. The strong dominate, the weak get crushed, and true peace doesn’t exist. Ragnar quickly learns that surviving isn’t enough in a world ruled by pirates, Marines, and hidden powers pulling the strings from the shadows. He knows how the story is supposed to go. He knows the prophecy, the Pirate King, and the future awaiting this world. The question is, will he follow it? Will Ragnar chase the title of Pirate King, aim for something far bigger, or tear apart the path fate already decided? And if he changes too much… will the One Piece world remain the same? Note: Ragnar is a strong-to-stronger MC if that’s not for you, please don’t read. [Author’s Note: One Piece is owned by Eiichiro Oda. This is a fanfiction written by a fan, for fans.]

Elric was just an ordinary guy—until fate threw him into the chaos of the Marvel Universe, right in the middle of war-torn Sokovia. In a world where the rich gain power through cutting-edge technology and the poor are left hoping for a lucky mutation, Elric had no advantages. No money. No powers. No way out. But everything changed one morning when he awoke in a mysterious white space—and met alternate versions of himself, each from a different world: Overlord, Naruto, One Piece, Solo Leveling, and more. Somehow, their souls were all fragments of the same origin—and they could share powers across realities. With their strength now flowing into him, Elric saw the path forward.

A modern-day beauty, Luna, is suddenly transported into the world of One Piece. In a world defined by freedom and adventure, she decides that if she’s already here, she might as well leave her mark. Who says women are inferior to men? If this world has a throne, then she’ll claim it and become its queen.

And that’s not all—her identity itself is far from ordinary. She begins recruiting crew members from the original One Piece world, including Kuina, Carmen, Kaya, Nojiko, and Uta, all of whom survive and join her journey.

Starting from East Blue, Luna crushes every obstacle in her path—rising to become the Fifth Emperor of the Sea, overwhelming the Marines, destroying the Celestial Dragons, beating down the Five Elders and Imu, and ultimately dominating the pirate world.

Then Uta is yours.” Usopp, Sanji, and Nami: “Kaya… Carmen… Sis… what happened to you?!” Vegapunk: “Unbelievable. My research abilities are inferior to a teenage girl.” Sengoku: “Why is an all-female pirate crew this terrifyingly strong?” Garp: “You’re his granddaughter, aren’t you?” Luffy, letting out a sigh of relief: “Good thing no one’s stealing my title as Pirate King.” And deep within the shadows, Imu screams in despair: “Can someone tell me… how do you fight the Void?”

After waking up, Renji discovered that he had arrived in the world of One Piece and had become a member of the Whitebeard Pirates. Thinking about the terrifying strength of the powerhouses in this world where battles could destroy islands and shake the seas Renji felt extremely uneasy. Was he really transported here just to become cannon fodder? Fortunately, a God-Level Pickup System activated. “Ding! You picked up 1 point of Strength!” “Ding! You picked up 1 point of Speed!” “Ding! You picked up 1 portion of Combat Experience!” From that moment on, the Whitebeard Pirates gained a division commander who remained calm and low-key, quietly observing from the sidelines while steadily growing stronger. Sengoku: “Damn it, this division commander is even harder to deal with than Whitebeard.” Monkey D. Garp: “With him around, how are we supposed to overthrow the Whitebeard Pirates?” At the rear of the Marineford War, Renji revealed a gentle smile. “Stop arguing… just hurry up and start fighting.”
