General Fics
Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.
Serious Saitama
by Gaming Ikari
- Recommended by: Psyckosama, Robinton
- Status: Dormant (last updated July 2017)
- Synopsis: 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.
- Tags: Adventure
- Comments: While it's just starting up, it has the potential to be great. Just the first chapter with the S-rank heroes giving their opinions on seeing Saitama fight for real and understanding the fact that he's on a whole new level is worth the read.
The (Un)stoppable Threat by Grillefirer
- Recommended by: Sophiebyophie
- Status: Ongoing
- Synopsis: Saitama is the world's strongest being, able to defeat any and all threats, no matter how powerful. But what happens when he becomes the threat?

The Strongest Hero by The Lone Lobster
- Recommended by: Sophiebybophie, Happy Man
- Status: Ongoing
- Synopsis: 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?
- Comments: If you thought that Saitama having to start as a C-Class hero was just a cheap way to create conflict, then this fic is definitely for you. Easily one of the funniest and most enjoyable OPM fics out there. One of its strongest points is taking characters that were killed way too soon, such as Mosquito Girl and the rest of the House of Evolution monsters, and turning them into enjoyable additions to the cast. Tatsumaki and Fubuki's expanded roles are worth of appreciation as well.
- Tags: Humor, Adventure
- Status: Dormant (last updated May 2017)
- Synopsis: 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.

The Bald and the Esper by silenthero27
- Recommended by: Tropers/Happyman
- Status: Complete (Season 1)
- Synopsis: 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?
- Comments: A pretty enjoyable story, especially if you're a Tatsumaki fan. It will take you little time to figure out why this story is the most reviewed OPM fanfic so far.
- Recommended by: Zoic Alcelaphine
- Status: Dead; last updated November 2017
- Synopsis: 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.
- Comments: People think that Saitama is a dangerous villain, and various heroes try to arrest him. Things escalate from there.
- Recommended by: Lyra_Dhani
- Status: Complete
- Synopsis: Saitama wonders if there was any particular emotion that made him decide he wanted to keep the cactus. He can’t remember.

Colourless Saitama and his Years of Training by Rironomind
- Recommended by: Orchidnecromancer, Catamaran
- Status: Complete
- Synopsis: A lonely eggman living in the 21st century finds a cyborg who endeavours to keep him. (What kind of half-assed backstory is that?)
- Pairing(s): Saitama/Genos
- Tags: AU, Domestic, Fluff, Humor, Angst, Hurt/Comfort, Slice of Life, Adventure, Slow-Burn, Developing Relationship
- Comments:
- Orchidnecromancer: This fic is one of the best, if not the best Saigenos fics I've read. Rironomind takes every trope and convention you see in this fandom, and twists them into something new and exciting and painful, while perfectly capturing the melancholy humor of the original story. Well written from start to finish, with perfect characterization too.

- Recommended by: Sophiebybophie
- Status: Complete
- Synopsis: Behind every great man is a great woman, that's how the saying goes. But how can that apply to our favorite bald hero? Simple, what if he had someone beside him even before the start of his grand adventure? Someone who had been a constant presence, an unrelenting beacon of support, and whom never failed to care and love him no matter what happened? Meet (Name) (Surname), or Mrs. Saitama as she's teasingly called by her friends ever since she married the adorable buffoon she calls a husband. Sure, he may not be the shiniest egg in the carton or have an office job and raking in a 6-digit paycheck, but you wouldn't have him any other way. Because while he may be a NEET to some people and a cheater to others, that will never change the fact that he was your hero…as you were his.

- Synopsis: Some parts aren't so easy to replace. And the injuries you can't see can be the most dangerous.(Genos gets a concussion, Saitama frets.)
- Pairing(s): Saitama/Genos
- Recommended by: ThisIsRidiculous
- Status: Complete
- Synopsis: “You want me to teach you how to what?” Saitama asks as they’re clearing up the dishes from tonight’s meal. Genos washes; Saitama gathers up the garbage. Tomorrow is burnable garbage day. Each pot and plate and dish is scoured to sparkling perfection before it goes into the drying rack. “Relax,” Genos says. “Sensei appears to have a lot of experience in the art of doing nothing, and recently Doctor Kuseno suggested that it would be beneficial for me to do the same.” “Doesn’t that guy make robots? They’re not exactly like humans, you know,” Saitama says. “And it’s not like I spend all day lying around the house. I’m a hero, a hero.”
- Pairing(s): Saitama/Genos
One Punch Man: Hero's Harem byF-ckthesystem125
- Recommended by: Knight Spark
- Status: Ongoing
- Synopsis: Power can bring about fear. Fear can lead to yielding. Yielding can lead to mercy. Mercy can lead to Redemption. Redemption...can lead to so much more if given the chance. I do not own One Punch Man. It belongs to ONE! Co-author: IcySnowSage.
- Pairing(s): Saitama/Harem
- Comments:
- Skunkbrains: Pretty decent harem fic. Genos is a bit more of a jerk in the beginning than in canon, but it's nothing character destroying. Only real complaint I have is that the author slightly overuses TTT and TTBH a bit too much as punching bags/idiots. My favorite chapter is when Saitama's subconscious basically has to beat him over the head into realizing he's actually attracted to his monster buddies.
Lady Boros, Dominator of the Heart by Josh Mystic
- Recommended by: bf2234
- Status: Ongoing
- Synopsis: After being guided by a prophecy delivered by an ancient seer, Lady Boros Dominator of The Universe has come seeking a champion that is capable of surpassing her might, but what she finds waiting for her at her journey's end is far more than she could have foreseen, not that that's a bad thing of course.
- Pairing(s): Boros/Saitama
- Comments: An interesting fic with a genderbent take on Boros of the Dark Matter Thieves arc coming to Earth at the start of One-Punch Man canon and falling in love with Saitama. Hijinks and romance ensue as genderbent versions of Deep Sea King, Subterranean King, and Sky King also show up to vie for Saitama's love while Boros tries to come to terms with her emotions and get Saitama to love her.

- Synopsis: This is the chronicle of how the strongest man in existence came to be. Or at least how that liar converted all his deceitful words and lies into truth. Someone becoming strong from their weak state upon a time in their life before everything began.

Crossovers
The characters are written into a different world/universe/fandom than the one they are typically from.
One Punch-Gamer by Saint Infernal Neos
- Recommended by: notabot, Prometheus117, Robinton
- Status: Completednote
- Crossover with: Sword Art Online
- Synopsis: He KNEW this was some sort of karmic joke. He shouldn't have laughed at other's seemingly 'silly' problem, even if said other was an anime character. Now, he was forced to accept that yes, ending everything with one punch could get frustrating, especially for a Gamer. Then again, when trapped inside a game where Death is very much real, that can only be a good thing...right?
- Tags: Harem, Parody, Adventure
- Comments:
- notabot: One of the best crossovers I have read recently. It actually made me glad to have watched SAO in the first place since this fic is so good.
- Prometheus117: Five days before the official launch of Sword Art Online, Kazuto(Kirito) and his younger sister Suguha spot One Punch Man on the TV and proceed to watch and enjoy every episode of it, resulting in the siblings connecting more than they have in years. But then Kirito plays Sword Art Online and proceeds to get stuck in it along with ten thousand other players. Which, by the act of an incomprehensible being known only as Fate, glitches the system to give Kirito the power and garb (though not baldness) of Saitama. The story then proceeds to combine awesomeness, funny, and heartwarming as Kirito goes on through the world of Aincrad and beyond with his newfound abilities and allies as he illuminates in more ways than one his Hero, all while finding his own path to heroism. Proof that even something with as much of a Broken Base as SAO can be made instantly awesome with the application of a little punching.

Add ReviewFear Not the Psyker--fear the Psyker's FRIENDS by Afalstein

- Tags: Humor, Friendship
- Comments:
- toxinvictoria: A enjoyable cross between One-Punch Man and Warhammer 40,000 that explores Fubuki and Tatsumaki's relationship in addition to the expected fights. Manages to be original flavor.
One Punch Arch by 8-bit pirate

Unsure of how to train as huntsman he decides to do the only workouts he really knew but intensified: 100 push-ups, 100 sit-ups, 100 squats, and running 10k. EVERY. SINGLE. DAY. And the result is he became the most powerful being in remnant. Too bad everything ends with a single punch now.

The Fist of Remnant by BrightestDarkness
- Recommended by Corrosion, Robinton
- Crossover with RWBY
- Status: Dormant; last updated January 2018
- Synopsis: In the ruined crater that once held the Forever Fall, forces beyond Remnant's comprehension are stirring. Well, maybe more strolling around looking for Udon and the way home than stirring but that's beside the point; a bald justice has emerged into Remnant with his sidekick, seeking justice and defending the weak. After they fix the moon first that is.
- Comments: One of the best One Punch Man crossover fics out there. Each of the characters in this fic stay true to their canon personalities, such as Genos being serious about everything, and Saitama being his usual self. The humour is great, and the author does an amazing job of contrasting Saitama's general invulnerability and plainness with the other more complex characters in the RWBY universe.
- A bit more cracky than One Punch Man canon.
