Isayo. Seen by many as a weird white-haired girl that always wears a white lab coat. Some see her as their weird friend. And few see her as a worthy adversary.

What happens when Garou goes rogue and leaves everything behind after his rampage? What will Angelo do to guide his friend back on the right path? Basically a OPM Male Characters x OC but Garou is main love interest. Spoilers for One Punch Man A/N: Written before airing of OPM S2 Ep 3 (I've read all the manga however) and after. So keep that in mind just in case early chapters don't add up with the canon timeline. Following the canon timeline as best as possible. OPM, it's characters (and some of the plot) belongs to ONE. Any images used are by Yusuke Murata, the manga artist for One Punch Man.

Sins - One Punch Hero by Sins_of_Fate

Being born 'Quirkless'? He can handle that. Being bullied? Hah, he knows how to handle bullies! Becoming a manga artist and the strongest human alive... Umm... what? This has got to be a joke. Because seriously! It feels like everything is starting to get out of hand! Becoming a hero for fun, beating Villains with just one punch, everyone around him seemingly developing familiar superpowers, monsters literally popping out from nowhere and now carrying the fate of the world on his shoulders. And so begins the story of Izuku Midoriya, the strongest superhero on this world, with epic battles and comedy that's just perfectly fine in this world of quirks. Time to be a Hero!

The Blond Cyborg || Genos x Reader by FantasizinDaydr3amer

"Whoa, hold up! You're saying I'm living with two guys now?!" "Technically, I'M the one living with two people," Saitama crosses his arms. "What if I walk out of here, and people see me staying with two guys? They might think I'm some slut or something." Saitama snorts, "don't worry, it's not like you'll fall in love with one of us anyway..." ------ Ever since you grew up, you've been running for your whole life...well you still are. All you did was mess your life up. SHE kept coming for you. SHE won't leave you alone. SHE'LL do anything to get you back, since you're her talented fighter. Not your fault you're so good at everything. You have an interesting back story/past due to many anime crossovers you've encountered with. This includes, Tokyo Ghoul, Naruto, Black Butler, Kiss Him_Not Me, and Attack on Titan! (And obv One Punch Man lol) ____ I do not own One Punch Man or the other animes mentioned. ••••• [Status: Completed || 2018-2020]

King Hiroki The Hero of Heroes (Kokujin No Tenkousei NTR AU) (Oneshot) by LIGHT-TIMES

After finding out what the ones who betrayed him did to him. Hiroki ran away, traumatized, disgusted, and terrified. And he kept running until he got lost. Eventually he was face to face with a monster that scratched his eye. And after many encounters with more monsters, he accidentally became the world's strongest man, but had abilities that made him live up to the name. Then, he went back home after a few years to confront the ones who betrayed him, not knowing, three of them (Kaede, Kanoko, and Ayumu) regretted it and now hate themselves because they miss him a lot, while the one who doesn't (Nao), hasn't realized what she lost until it's too late and Hiroki has moved on and already fixed his life. (I know it's a bad description, but this was rushed) (Oneshot) I do not known Kokujin No Tenkousei, it is owned by Terasu MC (If I did own it then the betrayals wouldn't have happened at all, or Hiroki would've beat up Kokujin) and OPM belongs to Yusuke Murata, Shueisha, Viz Media, and One. This is for entertainment purposes only. The pictures used belong to their rightful owners, this is just a Fanfiction idea for entertainment purposes.
