You mean avatars that are half human and a vampire or actual vampires and werewolves? if it's full vampire and werewolves that's hella creepy to have or want as avatars
Either way. It can be like the "easy to get" avatars as vampires and the "harder to get" avatars as both vampire and werewolves
These would be good for a Halloween promo or hunt or even just to have in the store. As far as year around, nah. This is a college based game, vampires and werewolves don't roam around colleges other than on Halloween in costume.
Still cliche as can be. Why can't there be like a princess fairy one man ? Halloween isn't "scary" stuff all the time
