>>279811445 (OP)>VigilantesThe main plot would still be possible, as Knuckleduster would rope PTSD Kung-Fu Jesus Viking Thorfinn into the vigilante business, and he'd probably tag along since they don't kill anyone
I tried thinking what would be different, but it turns out replacing Koichi with Thorfinn doesn't change too much:
>Although way better in actual fights than Koichi, he'd rarely actually fight and instead try to either talk-no-jutsu 'roided villains out of rampages or let Knuckleduster handle them while going out to save civilians>Still the type to do community service if someone told him about it>Pop would still tsundere over him even without the backstory tie-inDifferences:
>Lack Koichi's quirk, so he might have a tough time scaling walls and catching up to people if his superhuman stunts are scaled around Knuckleduster's capabilities>Would spend more time comparing and contrasting what a "peaceful" society looks like relative to where he lived prior; would also have to learn a lot of basic things about modern society (which would be played for comedic effect sometimes and be a talking point at others)>Far fewer confidence issues than Koichi, though his pacifism and refusal to fight in situations that even Koichi would go for would then become his main "fault"
