The noir hero is a knight in blood caked armor. He's dirty and he does his best to deny the fact that he's a hero the whole time.
My Sin City heroes are knights in dirty, blood-caked armor. They bring justice to a world that gives them no medals, no praise, no reward. That world, that city, often kills them for their brave service.
What I want to bring back to superheroes with this project is a sense of play. Things have gotten so dreary. The heroes have gotten so ugly that even their muscles have muscles.
