The adventures and struggles of a bald man whose strength surpasses the gods themselves, and a one-eyed goddess who seemingly has way too much time on her hands. Together, they set out to become the greatest heroes there ever was... or really, just to have fun beating up monsters and villains.

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).

King bought that new VRMMORPG everyone was waiting for! He played the game, and it didn't disappoint! Eh? Why's the HP, MP and ST bar all in real life? Why can he take out items from the game? Why can he cast spells? Most importantly... when did he get so strong? (AN: May contain cameos/appearances of characters from other anime/manga, or more. I own nothing but the fanfiction.)

Mochi is a former stunt professional with a knack for inventing. She has managed to make it into the top ranks of class C. Does she have what it takes to rise higher? Please don't take this too seriously, peace.

My oc managed to get his ass isakied

King eats GOD pie, and takes the Infinity Gauntlet from Goku.

ChatGPT refuses to write anything 'explicit' or 'stimulating', so this was the best I could do. I'll figure something out eventually. Geryuganshoop is also not available as a character tag, apparently.

Hard & Loud goes into a heated debate with Speed & Precision.

[I am not good with titles so sue me] The silver master challenges the King to a dance battle.

I did this as a test, and ChatGPT did not disappoint. A little short for my taste, but funny enough (comedy is subjective, people) where I decided to post this here.

Cuando la noche es cálida y las palabras correctas se niegan a salir, meter a Tatsumaki a la conversación se vuelve bastante conveniente para ambos.

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!

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!

Nunca he escrito un buen sumario, no pienso cambiar eso

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