I was going to go on a date with a Cosplayer, but for some reason I wake up on a beach in One Piece! But don't worry I have a System, the thing that grants it's Host strength at an easier pace! Wait what do you mean I can't use Haki!

This is based in the events happened after the telephonic conversation between Mugiwara no Luffy and Big Mom (episode 572 of the anime, more or less).

Shanks tenía un plan excelente. Iba a rescatar a Ace, el hermano mayor de su hijo, antes de que la Marina pudiera exhibirlo, y finalmente reunirse con "Anchor" en el Nuevo Mundo. Pero resulta que no solo Luffy no estaba a salvo bajo la custodia de Rayleigh en Sabaody, sino que había logrado infiltrarse en la prisión más segura del mundo. ¿Qué demonios...?

Whitebeard felt shocked when an unknown person walked into his office, which requires multiple locked doors with a keycard or key, a business he runs with his family. What he had to say shocked him, but not long after, he needs help to resolve a serious matter. But asking a hitman/informant might not be the best idea, but he has little choice left. Mercenary Ace. Assassin Ace

I always hated idiotic tropes, so I decided to reduce them and make a few major changes. Basically story of Strawhats who take no shit.

After saving Nami and Chopper on a strange island, Luffy uncovers one of Nami's secrets, shifting their dynamic. The crew reaches Amour de Isle, a mysterious kingdom where things aren't as they seem. When Nami is swept off her feet by a charming stranger, Luffy must act to keep his navigator close and uncover the island's truth.

Duo Demonic travel to go Lounge Town where Pirate King Gold D. Roger born and Dead his City! We walk around city to learn and we meet anyone person from Straw Hart Pirate!

A complete AU of the hybrid offspring of Arlong and Nami, who set off to find their place within the world and save a hidden island where humans and those of the Fishmen race coexist from the dangers of those who seek to destroy the very balance of the island.

An adventure that takes you to the heart of Impel Down, right before the epic Marineford War, with an unexpected twist. Meet our self-inserted character, who finds himself in the shoes of none other than the comical and infamous Buggy the Clown. As the story unfolds, this new Buggy is thrust into the treacherous depths of Impel Down, the world's most impregnable prison.

"Have you ever thought a brave, adventurous and independent pirate would give up everything for a family and still be happy? Well, maybe I was wrong"

After one too many at the bar, Nick finds himself in a new world. Captured by the Marines and sentenced to death, Nick thought his life was over. That is, until a certain cat burglar rescues him. For a price of course. His journey of piracy begins, but will he be able to survive? Only time will tell.

What if the time and space between Luffy and Robin was just a little bit closer together, and the two happened to meet at their young ages? Inspired by xox1melly1xox's fan comic, 'Parallel'. Enjoy! :)

"When do you think people die? When they are shot through the heart by the bullet of a pistol? No. When they are ravaged by an incurable disease? No. When they drink soup made from a poisonous mushroom? No. It's when they are Forgotten." - Dr. Hiriluk. This is the Story of Adam D. Valentine, a Lunarian on a quest for True Immortality. Full synopsis in the first chapter.

At just fourteen, he took the reins of a crumbling kingdom after his father's demise. With sheer willpower and a mind as sharp as a sword, he transformed it from the brink of ruin into a Kingdom that now captivates the attention of the entire world. But his ambitions don't end there his eyes are set on dominating the entire World.

(Jan 27, 2025. I deleted an author's note chapter that was cluttering up the middle of the story and as an unforeseen result, chapters are a little broken right now. FFN can't decide if there's 45 or 46 chapters and keeps skipping around. I ask for a patience as I look into resolving this issue. Or maybe just waiting for the site to figure its life out.)

Luffy doesn't start his journey alone, being joined by the four children of the legendary Whitebeard himself! His journey to becoming King of the Pirates will take a new, drastic turn! Based on Ash & Rubber by mtnetsurfer.

Shanks had a great plan. He was going to grab his kid's big brother before the Navy could put him on display and then finally meet up with his Anchor in the New World. Then he finds out that not only was Luffy not safely guarded by Rayleigh on Sabaody, but he had broken into the most secure prison in the world. What the hell?

Self-Inserts all suffer one fundamental setback: they see the future once. One snapshot of a future that will swiftly go off the rails, and even then, their information is limited and flawed. Treva, future-seeing ten-year-old and distinctly not a Self-Insert, does not have this problem. She does have a lot of other problems, though. Not least of which is being a ten-year-old.

They were six and twelve. They were taken. It's been six years. Ace, Luffy and Sabo were raised with the marines. It was all they knew how to be. The Whitebeards just came to the island for a stock up. They did not expect to be called back because of a devil-fruit-wielding brat of a government dog sighting. The Whitebeards came expecting a fight. They got family instead.

What if there was one extra straw hat how much of a difference would it make?

Maude woke in the world of One Piece, where only the strong survive. With the Hunter's Notebook, letting him grow stronger by defeating foes, he vowed to rise above all. His targets: Warlords, Admirals, and Emperors. From that day forward, he was a calamity—to pirates, he was a nightmare; to the Navy, a scourge. But to himself, he was simply the hunter destined to rise above all.

A "One Piece" superfan and Holy Paladin main is transported into the pirate world. Wright, now wielding Azeroth's Holy Light, spends 18 years mastering his power. Declaring himself a Swordmaster, he slashes enemies while reluctantly healing his Marine squad. The Marines joke: "Fleet Admiral, remember to heal!" Wright groans, balancing heroics and responsibility.

Remake of original story: Not all treasure is gold and jewels. In the middle of some strange ruins, the Straw Hats accidently end up watching their captain's memories of him and Ace. They all knew that there was a strong bond between these brothers; only now do they see how deep this bond was and how much pain had been caused.
