Anons...I am disappoint. There is a supernatural world that exist outside of Twilight. Like Mercy's Thompson Series and their awesome werewolves, the Sookie Stackhouse with her semi-cool werewolves, the slight mentioning of werewolves in Rice's Vampire Chronicles, and Jim Butcher's werewolves in Fool Moon. Those are only a couple of examples. There is no set rules on how you make your werewolves or vampires (obviously) so you can do anything.

Oh Twilight...You.Ruined.EVERYTHING!!!!!!
