Genetically altered Class A hero Samurai Catgirl is on a mission to find her younger counterpart and erase every trace of a horrific event that happened in the past. After spending so much time working on this mission alone, she finally finds allies in Genos and Saitama. Written for fun. Some themes are kind of mature.

Top-class housekeeper Genos meets the worst case of 'untidy' when the slob of a rich guy Saitama hires him. Everyone has a favourite way of doing things, be it chilling or cleaning. Point is to get along despite differences…Hopefully. (Human AU)

King gets Admin status.

"I'm a therapist for fun - I mean, uh, a real professional therapist. And my name is Saitama. Now then…Tell me," he paused, clicking his pen. "How's it going?"

Bam is the lone student of a distinct martial arts school. Traveling to an island with her friend, she enters a martial arts tournament for the prize money for her dojo, finding new friends, rivals, monsters to battle, and even love? Will she win the tournament, or will someone make her realize not everything’s about the fight?

Mizuki is an active hero that tries to help all types of people in need. Anything is better with a partner so why not the Tornado of Terror herself Tatsumaki? This actually has a story and smut in later chapters. Futanari

En sus días de entrenamiento para convertirse en un héroe, Saitama conoce a una anciana que le ofrece darle predicciones sobre su futuro en el amor. "Dime, Saitama, ¿no quieres saber cómo será tu futura esposa?"

Due to wanting closure on who her father is, the Fubuki Group member and B Class Hero Lily makes a gamble that he was within the Hero Association and goes through rather unconventional means to acquire said information. She turns out to be correct, but little could prepare her for the fact he was the Strongest Man on Earth!

You all know the thoroughly disproven theory that Blast is a future version of Saitama. But what if instead Saitama really was Blast? Basically he's older and does all the stuff we know Blast did, except the Cube and God shit. No idea whats up with that so I'm not touching it.

Saitama se topa con la realidad que hay cosas mas dificiles en la vida que acabar con terribles enemigos, como matar un mosquito, o empezar una relación con su peliverde menos favorita. ¿Como terminaron Saitama y Tatsumaki en esto? descubralo aqui!

Just One punch man but what will happen if Saitama's feats get recognized? a little bit of romance and some changes, and the story will be almost the same but a bit different. (I started editing every chapter.)

Todo lo que Fubuki quería era escribir una simple confesión de amor a Saitama.

Once an average salary man, Heikin Nozoki turns into the monstrous Hypnoza after six years of dedicating his free time to hypnosis! Now a monster, Hypnoza only wants two things: world domination, and a harem at his side while he does! All done with hypnosis, of course!

Tatsumaki faces a wave of different feelings after the Monster Association arc. Chapter 14 - Hmmmm...

One mission. Two heroes. Three ways it all goes wrong: 1) They fight one another and take things too far, 2) Lose the hideout, 3) Cannot complete the mission. Hm…Eh, they'd both rather get the work done sooner than later. And, hey, they're both hard to kill, so not to worry, yeah?

Those 5 times Saitama was surprised(!) [And that 1 time he could not explain with words]

Garou swears vengeance. He had shown weakness…Never again…The goal? Destroying the Hero Association.

Commissioned story. Mumen Rider has a mission to keep humanity safe from the monsters that threaten it. And he's discovered quite the unique way to go about it.

A monster crosses onto a magical forest, finding something it never had.

It's that whole stereotypical schtick once more-go to sleep, wake up in some new world with the Gamer powers. Only, I've been dumped into the body of quite the high calibre individual.

The first wig was an orange monstrosity: cheap, ill-fitted, and frightful to behold. The second wig was blue and beautiful, flowing and lustrous and worthy of Amai Mask himself. The third wig screamed Keep away! as clearly as a viper's bands. The fourth wig was merely an unfortunate accident. Will the fifth wig be the one?

After a terrible subway accident that killed a young girl, Fubuki gets depressed and gradually realizes that the heroic path may not be for her. Indeed, her horrific meaning of life is to become an empress who will subdue all humanity."But how?" You might ask. You will discover it by reading this story to the end. NOTE: This story includes the manga and webcomic.

A novelization of the recent events of chapter 166 of One Punch Man! (a One Shot!)
