As an anime and manga fanatic, I noticed that some animes and mangas use a rating system when categorizing characters. For example, Yu Yu Hakusho used a rating system for demons and Tokyo Ghoul used a rating system for ghouls. These rating systems ranged from C class to S class with the C class being to lowest rating and S class being the highest rating. When I started writing The Young Guardians Series, a friend of mine wondered if I should use this rating system to categorize superhumans. I never did it, but now I am thinking of using it in my new superhuman series with C class being the weakest and most common superhumans while S class represents the rarest and strongest superhumans.
