The term 'SUPERHEROES ALWAYS HAVE THEM' is referring to NEMESES, which is a seven letter word. A nemesis is a person's arch-rival or someone who is the exact opposite of them. Superheroes often have NEMESES that are their equal in terms of power and intelligence, and they often have a long-standing rivalry. The nemesis is usually the main antagonist of the story, and they often have a personal vendetta against the superhero.
