The “Cthulhu Mythos” is a huge influence on modern horror, science fiction, and speculative fiction, including superhero comics. Versions of eldritch horrors from beyond time and space have appeared in countless comic books, primarily as patrons for sinister cults and foes for mystic heroes, although they’ve run up against quite a few non-magical superheroes as well.
