Only thing I can say about one punch, is oh that mosquito episode.One Punch Man needs to continue, honestly. It's not even a good story, just wanna see what kind of crap they can come up with.
The powerless feeling being a grown up man fighting a damn tiny mosquito to no avail, the sucker always flying away, yet coming back to sting. The feeling so familiar.
Then finally he slaps the damn overgrown mosquito to that building. Oh, the payoff. It felt so good.
