just an FYI to the author if you didn't know marvel has it's own version of vampires already in the form of the Blade and Morpheus comics so if you plan to introduce either the Blade or Morpheus series later down the line I'd suggest that you ensure that their's a clear distinction separating the strike the blood vampires and the Blade and/or Morpheus vampires as they would be separate and very different species of vampire.
