When an old man with the Open Open fruit offers Luffy the chance to redo his adventure, he takes it. Watch as Luffy goes back in time to change history with more crewmates. LuffyxHarem! Rated M for sexual content and cursing. R&R. I don't own One Piece. (DISCONTINUED! UNDER REWRITE!)

What if he had been inspired by saitama to become the very thing people expected of him. Btw this is going to be very slow because I'm going to have a hard time writing the chapters. Not due to length but figuring out how to plan them.

This is the story of a new hero joining Saitama and Genos on their adventures. This story focuses on his experience of climbing his way through the ranks of the Hero Association alongside these two powerful heroes. Please feel free to criticize. I attempt to update the story with new chapters once or twice every month.

Six months after the world ends, a samurai and a little girl walk into a bar. (In which the Joui war was cut short on account of the Earth being blown up, and Otose watches a seventeen year old Gintoki attempt to raise a four year old Kagura.)

Two incredibly stubborn and endearingly stupid samurai idiots fall in love. With each other. (Because sometimes trouble can attract the good kind of trouble, too.) {Slow Burn - the slowest, sweetest and burniest} / [Currently Being Edited.]

What if Saitama was actually praised and acknowledged for his feats instead of always taking the brunt of mob mentality and credit stealing? Come and take a gander at this tale which seeks to answer such a question all the while at Saitama's expense!...What you didn't HONESTLY think he was gonna have it any easier did you?

What if our favorite bald hero happens to have a little sister? That's all I'm asking. "Stupid bald brother." "Shortie little sister." They are ordinary siblings who lives in a not so ordinary place, where monsters and villains appear most of the time. Let's see how the siblings survive their quite chaotic life.

An esper and a nobody walk into a bar. In retrospect, this was a pretty novel base for a relationship. Sequel to 'Dinner Date', will probably just be a collection of one-shots with maybe a loose plotline.

The Subterranean invasion was real, and Saitama's right in the middle. How will this change what happens and who meets who? Find out with me! I don't write romance, so no formal pairings. Ships? Dunno, maybe a few teases eventually. Definitely not the focus, though.

Ever wonder what would happen if the heroes of S-Class were to go against the Caped Baldly? Cause I have... Watch as the S-Class of the Hero Organization go against the man of the hour, and truly see what Saitama really is.

A long story focused around the constantly developing relationship between Gintoki and Tsukuyo, split into 5 Books. Book 1: Gintoki and Tsukuyo are slowly becoming a couple, but they decide to keep it a secret from their friends. As they start to catch on, chaos and hilarity ensue through the goal of finding out who is Gintoki's mystery lover...(Gintsu)

Madoka Akagi is an average high school student who resides in Z city. However she is isolated and ostracized in school because of her introverted nature and her idolizing the hero "Saitama the caped baldly". But how will Saitama feel when he eventually meets the girl who idolizes him so much? SaitamaxOC, Fluff/first crush, Genos and OC (friendship)

What if Tatsumaki lost a bet with Saitama? What if that single bet she lost paved the way for a new kind of relationship she'd never experienced before? Come along and experience the crazy adventures of excitement and love created by our two hero's! Saitama X Tatsuamki I don't own anything but neither do you

You see, Saitama accidentally became a god. Just accidentally.

What if things were changed, just a tad? That's all I'm asking. Find out as the story unravels, and the novice author continues to lament about how this was harder than he imagined. I hope you enjoy! (Currently being rewritten with *hopefully* better writing. No, this isn't discontinued.)

(AU) Tatsumaki, not willing to accept anyone being stronger than her, dons a disguise to catch Saitama off guard. All is planned out, but another step manages to appear. (Slight OOC)

It doesn't matter what world I end up in. I'll always find my way back to you, Tsukuyo.

Can the world's strongest hero break the walls of the world's most stubborn esper?

His heart felt empty of emotions. Her heart was full of anger and sorrow. He murdered her father. She wants revenge. When they meet...then what? Rated T for now. May change later. I don't own One Punch Man. It belongs to ONE.

With nothing and nobody left in her empty house, Kagura decides to embark on a journey to fix her broken family. What starts off as a naive dream slowly morphs into her involvement with the Edo underground scene and a clash of beliefs and ideologies. [Dark-ish, fantasy-ish AU; OkiKagu]

Tatsumaki has been beating herself up every since her fight with Saitama, craving a rematch and to prove she is his better. but when she learns his weakness with her sisters help will she be willing to pay that price? will she be willing to use her body to win?

Tatsumaki decides she feels bad for treating Saitama like shit, so she asks him out on a date with the intent of having it as an apology, she didn't know that it would that night that he would change her life.

I don't even know how crushed i'm at the moment. But i know that he has found his happiness. And that's not me. / Warning inside.

Small bits and pieces I felt should not be included in my main story. Reading the fillers is not required to understand the main story. (AKA 'When I'm too lazy to write properly')

A series of snippits based on the idea that Saitama was considered the number one most powerful villain and a God level threat for years by the entire world... and never knew.

Saitama was going through another one of his bad days, with the world rejecting and insulting him for being a bland fraud of a hero. But all it took was letting out a wish heard for the Strongest Hero to receive an offer he couldn't refuse and even one hell of a new suit. Now watch as two worlds of heroes and villains will clash, with Saitama in the middle of it all!

When aliens attacked and destroyed City A, Saitama planned to destroy the ship but saw a fellow hero on the ground and in need of help. By taking this little detour, Saitama actually brought more attention to his unmatched power with the other S-class Heroes. But first, they need to deal with the aliens on their ship. Wonder what this will mean for the Strongest Hero Alive!

Derek got very strong and did what needs to be done

Moving is always a tricky thing, and it takes time to learn about your new place and city, not to mention your neighboors. Maru is a girl with some special problems, which makes her move to Z City and she ends up as Saitamas new neighboor. There will be M rated chapters later. I am just a fan, and I do only own my OC.

The sky is his roof. The battle field, his home.

A rehash/retelling of the anime where a certain esper took the place of a certain cyborg we all know and love. Will the unlikely duo be able to co-exist like the two we're so accustomed to? Will it change them for the better, or worse? (Will have some changes and will have strong parallels with the anime. Cover image made by gintuk from DeviantArt.) SEASON 1 COMPLETE.

A hypothetical scenario of the final battle in One Punch Man. He fights gods, monsters and all sorts of wacky stuff happens.

After the war to save the Earth, the residents of Edo did the obvious thing. They reproduced. With their parents being great heroes, the new generation have more trivial worries in this safe new world. Like how much candy can they steal, from uncle Gintoki's stash without getting caught? each chapter includes the misadventures of the children of Gintsu, Okikagu and more.

A month after the Super Fight Tournament, the fighter Lin Lin decides to leave the city and dedicate herself to her well-needed training. She didn't expect, however, to end up in a journey with the tournament's champion, where they both share the common goal of getting stronger and, later on, a certain unknown feeling to both of them. Suiryu x Lin Lin.

The sequel to "Fight Me!" is here. Tatsumaki is still looking for that rematch against Saitama. Two weeks has passed since their last encounter as she is currently making her way to his apartment. What is going to happen this time around? Read and Find out. If you haven't already, please read "Fight Me" first. Rated T due to language. Genre: Slice of Life, Comedy, and One-Shot.

The title doesn't really have much to do with the story only in the ending it does. Read through the shopping and food these two go through! Sadly, no action fights, but don't fear. You might be blessed with fights in the future. (If asked to do more I'll gladly do so to continue the OPM One-Shots love!) SaitamaXTatsumaki

In which everyone acknowledges Gintoki Sakata is an excellent father. Oneshot.

Secure. Contain. Protect. These three words are the building blocks of an organization that dedicates their lives to finding and containing objects and creatures that seemingly defy all known sciences and physics. However, can this organization contain a bald man with the strength to punch through mountains and a cyborg that can spew flames from his hands?

Saitama keeps telling Fubuki that she needs to learn how to survive on her own. When will she ever learn? Hmm...maybe she just needs a little help...(Saitama x Fubuki)

Saitama's dream of an all-powerful subterranean invasion isn't a dream, it's fact. He wakes up to subterraneans grabbing his face and throwing him through his apartment, and everything that follows as the Hero Association tries to save the fragments of the human race.

Genos secretly hooks up his sensei, Saitama with a date, even after he told the cyborg to drop the certain topic. His date is the lovely leader of the Blizzard Group, Fubuki, although she is doing this from a favor. Would Saitama finally have a better life than just killing monsters with a single punch and watching TV? Or would this come back to bite both Fubuki and Genos? Rated T.

"If you have anything to say for yourselves, please speak now. Or forever hold your peace." "I, Puri-Puri Prisoner do hereby take, the S Class rank 14, Genos also known as Demon Cyborg to be my lawfully wedded husband." The buff man stood up. "HELL NO!" said cyborg readied to incinerate the man. My take on what happened after the Garou battle.

The abandoned district of Z-City. A place feared by both humans and monsters. Nobody knows for sure what is causing all the monsters who enter the area to disappear, but many monsters feel like they are up to the challenge of finding out themselves.

Having just barely survived the attack she endured from Saitama, the mutant, bloodsucking creature known only as the 'Mosquito Girl' awakens in a crater, heavily injured but alive. Entering a state of hibernation and awakening fully healed several months later, she finds out that much has changed in the world while she was gone, and discovers that she may have to evolve as well.

After single-handedly eliminating the Subterranean threat, Saitama might actually get his wishes of having his deeds recognized. But unbeknownst to him, he'll be getting help from the most unexpected person...

The sequel of "Family Dinner with The Yoshidas". Tsukuyo's family and Gintoki's family join together for summer vacation. During the vacation, some secrets regarding the two families are discovered.

Chap.525-551 Spoilers! [Rated M][GinTsu] Gintoki is depressed over the previous events while Tsukuyo decide to pay him a visit, as she can't help but worry about him... But typical Gintama-like: nothing really goes as expected for the both of them... [Complete]

Modern AU. He was the cancer strickened patient, she was the lovely nurse. She was the one who changed his mind, he was the one to finally take chances. He fell for her as she fell for him. The time he had left, with her, is all that mattered. Death wasn't as scary as long as she was with him by his side.

What if a being existed that could actually rival Saitama's unimagineable strength? And what if this being was a certain alien leader who came to earth because of a prophecy? Find out in this Fanfic! Takes place after Human Monster Garou Arc. Alien Conqueror Arc Redone. Rating may change. Inspired by AngelicIncubus story "The Strongest Villain".

After dating each other for half a year, Tsukuyo finally has the chance to meet Gintoki's whole family. But her boyfriend has no ordinary family. Other than a father, who happens to be the dean of their school, he also has four siblings. Will they accept her? Will they like her? Will they ask them to break up? Mostly family fluff. ONE-SHOT. Might have prequel or sequel.

What would happen if Saitama meet and save our favorite Esper who will following him around like a lost puppy...or like a Fangirl. Follow Tatsumaki when she learn from her idol about what it mean to be a hero! Saitama x Tatsumaki. Warning: OOC-ness!

"Stupid baldy," lowering her face, Fubuki muttered under her breath "I swear, I'll get you one of these days," Ape stifled a laugh "Get him to join the Blizzard Group or-?" Fubuki pursed her lips and felt her face get even hotter.

In this story, Enies Lobby ends tragically and Luffy is taken to be executed. What will the Straw Hat Pirates do now that they cannot be pirates any longer? Will be 8 Chapters!. LxN, ZxT, UxK etc... New Chapter every Thursday!

A pokemon fanfic that is still being worked on!
