The Strongest Man (Tatsumaki x Reader) by Immapotato01010

Basically a life where you become friends with Saitama and Genos. Then meet up with the green haired loli. One Punch Man is copyrighted by VIZ Media. This is basically a fanfic, and some parts of the story don't follow the plot of the Anime/Manga. Warning: Story is very biased on how I envision the plot to go. Lots of parts will be very different or completely changed from canon sections. Just saying.

{Discontinued}A Mutual Feeling (One Punch Man Fubuki x Reader) by WiseStrawberryFroggy
17 parts Complete
Wanted to make one of these for a while. Hope y'all enjoy it! :] Y/N is your custom character. Imagine Y/N however you'd like, just make sure it's appropriate. But for purposes of neutrality for everyone, I'll try to refer to Y/N in They/Them pronouns, but PLEASE change them to your preferred pronouns for Y/N. Y/N is a normal person living in City Z with their roommate. Although Y/N isn't THAT normal. Having the inexplainable power to distort space and time to their delight, they decide to become a hero after a few incidents. But while a hero, Y/N meets Hellish Blizzard, a hero at the top of Class B, who is intrigued with Y/N's capabilities. I'm too lazy to write the rest of the description.

Art of Manipulation |One Punch Man| |Reader Insert| by Red__Ruby
21 parts Complete
Saitama - A hero for fun who has inhuman physical abilities and can defeat enemies with ONE PUUUUUNCH. Genos - A hot, edgy cyborg that can shoot lasers and fire. Y/n - A sadistic hero with powers that she legally should not have. With abilities to manipulate living, sentient beings, throw shit around with your mind, and every kind of badass psionic power, that granted you to becoming a Dragon-level threat! Wanna know the best part? You are a cruel piece of shit always looking to make someone deserving of it scream. Whenever there's a fight, you waste no time in showing brutality. When Saitama gained his inhuman physical powers, you and him accidentally crossed paths, which led to a fight. You won. Now, at every chance he gets, he tries to fight you, or asks. He offered you to share his apartment because why the hell not, he's bored, and you're strong, do the math. You accepted because yes. You may be a hero, but something from your past is holding you back, and your alliances turn fickle when a chance of freedom turns up. #1 in genos Highest Ranking #1 in saitama Highest Ranking #1 in onepunch Highest Ranking (I own nothing!) (Everything and everyone belongs to their rightful owner!) (I only own the plot and my OC's!) (You own yourself!) (Warning!: Blood, cursing, gore!!)
King Is A True King by NeonAkabane

What if king was really powerful but he wasn't aware of it? King the rumoured strongest hero was really strong and had only humbled himself to the point of obliviousness of his own powers. What if he wasn't an average Joe that he thinks he is? (I do not do proof reads, if anything about my grammar or spelling is incorrect then kindly know I would not change it or edit it.)
