One-Punch Man Fanfiction
ONE and Yusuke Murata's superhero satire about Saitama, a hero so strong he ends every fight with a single punch and has gotten bored of it. On AO3 the fandom orbits Saitama/Genos (SaiGenos), the devoted cyborg disciple whose canon admiration writers happily push into romance, alongside a thriving Garou-centric corner after the Monster Association arc. The fanfic flavor mixes domestic comedy in that bare little Z-City apartment with surprisingly heavy meditations on what it means when nothing can challenge you.
