Boku no Hero Academia: The evolution of Superheroes

Boku no Hero Academia (BnHK) is an anime series that has been rising in popularity over the years in Japan as well as with the Western audience. Among the recent slew of movies and entertainment based around superheroes, Boku no Hero Academia is no different. This follows a current trend in the evolution and redesigning of superheroes' past and present. There are various similarities and identifiable inspirations that the author of BnHK has taken to flesh his characters, and yet there is a unique charm to one of the series' protagonists: All Might that carries forward to other characters in the series and makes it truly unique. All Might is very much the Superman of the series, and yet there is something about his character that makes him far more evolved and endearing than the big boy scout. How does this correlate to the current perspective and revision of the modern superhero?
