So far the checklist for 'Clint's' universe would be, which of have you heard of: 1. Avengers 2. X-Men 3. Fantastic Four 4. Inhumans 5. Yeah, sure let's throw Atlanteans in there. Honestly can't remember if they've gotten brought up before, but eh.
The first three usually seal the deal. Or really first two. It apparently is an odd universe where both exist now.
