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)

Can friendly monsters make an environment for coexistence with heroes? Can a man regain lost emotions? Can a girl finally get two years of torment lifted? Shall we find out? This is a bit of my own form of guilty pleasure that I have been working on off and on for some time. How long with this fiction go? I have no idea!

King gets Admin status.

What would happen if Saitama decided to not kill all the opponents he faced and instead tried talking them out of being the bad guys.

"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?"

Ambos eran dos almas acostumbradas a la soledad, conscientes de que la confianza es algo difícil de encontrar. Envueltos en sus propósitos, uno busca la paz y el otro proteger a los desvalidos. Aunque buscan lo mismo, el camino de ambos era completamente distinto. Pero las posibilidades de ambos eran tan infinitas... como las estrellas en el cielo que veían al anochecer. GarouxOC

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

After a brush with near-death, Tatsumaki realizes she cannot be the pillar of hope the people need. For the first time in a long time, she is afraid. The only one who can save her from that fear doesn't understand the concept of responsibility. There's more to hero work than a good fight and more to bravery than strength alone. The world needs a true hero, but what does that mean?

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!

Finding myself inexplicably on Earth, nothing like the one I'm familiar with, I have to navigate the Modern yet bizarrely advanced society as well as find a place where super-powered humans, cyborgs and monstrous beings exist. Even with my top-of-the-line cybernetics, advanced Training, and top-tier weaponry and gear - this place could prove to be a unexpected challenge.

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.

Just when Saitama was doled out enough points to become S Rank he wakes up in another world full of monsters, magic, and kings. How will he adjust in this new world?

Long before the start of what would become the story known as One-Punch Man, someone ended up within the world and has gone on to have his own adventures. Now with the 'story' about to start he attempts to guide the main players from the sidelines until such a time as they might need his assisstance. Unfortunatley as with most plans things don't go accordingly for long.

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.

She didn't need saving — but the baldy saved her anyway.

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!

Nunca he escrito un buen sumario, no pienso cambiar eso

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.(Major changes to the story don't begin until the end of season 1's events).

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