It would be perhaps some sort of vampire-werewolf hybrid. The only story I've encountered this is the Underworldfranchise.
Vampwolf; satanic spirit feline
A vampire-werewolf hybrid is commonly referred to as a "hybrid" or "dhampir."
Well it depends, if you mean what would they be called then there are a number of possibilities: Vampwolf Werepire Werevamp Wampire Vamwolf And the list goes on. If you are talking about how they would look, then you should let your imagination run wild! If you want an example then write in the search engine in deviantart: THATCHES SON, to see what a vampire and a zombie's son would look like. ( whoever edited my answer before- why did you delete my helpful example? what was wrong with it? plz dont do it again)
It will turn into a werewolf fully and cant turn back into a person.OR... Vampwolf! A Werewolf that can fly, turns back into a vampire during non-full-moon nights (and days) drinks your blood, and if it drinks your blood, you become a rather lupine vampire, but if it bites you and doesn't suck your blood, you become another Vampwolf.
