Too fast. It happened too fast... One moment Eustass Kid was on his way into the next half of his journey into the new world, but all it took was the random appearance of a mystical cube and a supposed hero called Blast to tear apart his ambitions and leave him stranded in a world he knew nothing about. Also, who the heck is this caped baldy guy? Hiatus/Cancelled.

Look, it's not MY fault the game bugged when I clicked two different worlds at the same time. Actually, I'm the victim! Getting thrown back and forth between One Piece and One Punch Man like a ragdoll isn't exactly what I call fun, and having a glitching out System doesn't make it easier! Well, guess I can't complain now. Might as well enjoy myself!

One Punch of justice raw english (warning this has really shit english(Trigger warning for all you reading nerds)) *it starts off at chp 17

Hello! My Name is Supremenoob00000 and I will be doing a revamp of OPJ! This story has numerous grammar corrections, which I have fixed to the best of my ability. Basically, the story is about Saitama becoming a marine and destr- oops, I've said too much :) All rights go to their respectful owners. Enjoy!

Saitama is suddenly swept away to the world of One-piece. The beginning of a new adventure? Surely; Enemies that don't die in one punch?...Not really.

Tras su muerte a manos de unos monstruos, Garou es transportado al mundo de One Piece. ¿Qué hará, una vez se de cuenta de que está en otro universo?. Aún mas importante, ¿Qué hará, cuando vea que ya no existe la asociación de héroes?. Todo un mundo de posibilidades a la espera de que el cazador de héroes descubra sus secretos, y quizás... ¿encontrar alguna forma de volver a casa?

For now, this will be a One Punch Man x One Piece crossover, but may expand into different worlds like I plan to do with multiple of my other stories. Summary; Saitama is a street rat that lives near a marine HQ. Since he was causing trouble, the cops called in the marines and they captured him and sent him to Impel Down for many thefts. Read to find out the rest of the story!

This story is about an even more OP, godlike Saitama in the One Piece world as a Marine. (The way he becomes a Marine is complicated, he's a bounty hunter at first.) Read and Review like always! (Oh yeah, and Luffy is still there, I repeat Luffy isn't out of action just yet... unless I decide to kill him, which I might) :D

Mumen Rider was in for the adventure of his life, but luckily his handy dandy Bicycle of Justice is there to help him through this unexpected turn.

Luffy gets caught eating the Gumo Gumo no mi, instead Shanks gives him a book from the grand line. Crack fix!

Luffy looks back on his life after he ate the one punch one punch fruit rather than the gum gum fruit.

Luffy knew it when he trained a little too much. And now he also has the power to end all fights with a single punch other than stretching like rubber, his life became boring. Yet there is still hope, there is someone that will make life fun for Luffy. But can he find her before it is too late? Smart as Strong Luffy

Luffy is fed up with Garp's training, and aims to beat him. So he does one hundred push-ups, one hundred sit-up, one hundred squats, and runs ten kilometers everyday until he becomes strong. There's only one problem... He's too strong. Watch Luffy as he goes through his adventure completely overpowered. Expect infrequent updates.
