Darkseeker

Used to be Humans but was infected by a virus which transformed them into Vampires called Darkseekers. They come out at night because sunlight kills them. They try to find and kill Dr Robert Neville who is the last man on earth. They are very quick and strong. They hate Neville because he kidnaps them and experiments on them to try and find a cure.

You sleep in the day? You must be a Darkseeker
