Vlad is a vampire (vampire sapien) in London that encountered Daniel while he decided to rest before attacking Beta.
He has been described to be rather neat looking, ith combed blonde hair and eyes with no pupils. His species are called Vampire sapiens which have commonly been mistaken in folklore as vampires.
He has had the ability to tract and retract two canine fangs from inside his mouth and he can transform into a bat which is two times the normal size and attack.
Though vampires do live forever in legend it has also stated that most of human folklore ways of vampire hunting are not affective so this might mean vampires do not age but can be killed. Daniel did this when he turned nto a giant hawk, and just as he was threatening Daniel's friends Daniel ate him.
