This could be a pointless introduction to a review (mostly because this is the second season and I couldn't be mistaken about it for so long), but it is actually something that is very original about Mob Psycho 100. ONE's way of building Mob Psycho 100 is the same he used to built One Punch Man. Parody doesn't need the same construction as straightforward manga as it is using a series of well-established archetypes as a launching pad to the story. This allows for the story to very elemental,as what's important are the gags and the weird designs, and how those interact in regard to our expectations of what a story should be and where it should go.
Mob Psycho 100 does exactly this: the bowl-haired timid bland protagonist whose actually infinitely powered, the suited regular con-man pretending to be special, the muscled Body Improvement club members, the big haired weirdo, the scarred villains, and so on. This sets up a narrative that is perfect for comedy -- which it does brilliantly, by the way --, and them subverts it with honest drama and action.
It's honestly amazing how ONE goes about this construction: is as masterful as it appears completely incapable and amateurish. It's so ingenuous how most of those characters are presented as bizarre stock characters and then fleshed out from out of the jokes to straight characters. It's such a refreshing, backwards way of telling a story. And of course, it helps that it is a great story: a Bildungsroman about the growth of a timid boy into a clear minded powerful being, surrounded by a great supporting cast, told through sensible and honest drama with hints of slice-of-life, kick-ass action scenes, and hilarious comedy.
