[She tilts her head, regarding him.] I'm not supernatural or a thing. Mutants are born with the X-gene that usually activates at puberty. It doesn't even always result in powers. Sometimes we just look different. [Usually that comes with different abilities even if it's just a rocky hide that's more durable, but not everyone can control metal or the weather.] My parents were very much human and until I fell through the ceiling one day I thought I was too.
But, yeah, there's probably more than I listed. And lots of flavors of those. I wouldn't expect all demons or vampires to be the same kind or anything.
