"Blame Stan Lee. He gave the Inhumans that sobriquet decades ago. In fact, the Inhumans had it first." Is that implying that the Inhumans "own" it? Or, that going forward it's another generic, association-free comic book title element?

Marvel owns everything, the characters are all fictional, so we can do whatever we want whenever we feel it’s proper.
But that said, certain phrases have certain associations, so using them will tend to imply something.
