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?

(AU) Tatsumaki, not willing to accept anyone being stronger than her, dons a disguise to catch Saitama off guard. All is planned out, but another step manages to appear. (Slight OOC)

Can the world's strongest hero break the walls of the world's most stubborn esper?

In which Hikigaya Hachiman gets married(again). Oneshot.

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? (Will have some changes and will have strong parallels with the anime. Cover image made by gintuk from DeviantArt.) SEASON 1 COMPLETE.

In the world of Steam Punk: After Saitama and Genos received an invitation to a big event, they decided to attend it; not knowing what exactly would await them in the next weeks: social differences, duels, the Blizzard group and sky pirates. [Steampunk AU: Genos is fully human but his arms are mechanicals]

Saitama keeps telling Fubuki that she needs to learn how to survive on her own. When will she ever learn? Hmm...maybe she just needs a little help...(Saitama x Fubuki)

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.

Saitama never thought he would be taking on an apprentice let alone two, however he feels like he could actually help this one out. She's a bit frumpy, not too strong or reliable, kind of mushy all around, and to be honest a total loser, but there's at least something to work with. He can help build her from the ground up and help push her through the limits.
