Deviant

A failed vampire.

Deviants are those vampires who have trouble transitioning from a human into a vampire. Unlike Sympathizers, they lose every bit of their humanity and become savage, feral beasts.

Deviants attack anyone and anything whithout thought of the consequences. Whatever was left of their individuality has been replaced by their blood lust. They are extremely strong and very fast.

It can take anywhere from 5 to 10 vampires to take one down.
