Sleepwalkers

Charles Brady and his mother Mary are Sleepwalkers, nomadic shapeshifting energy vampires who feed off the lifeforce of virgin women. Though they normally maintain a human form, they can transform into human-sized bipedal werecats, their natural form, at will. They have powers of both telekinesis and illusion. Their one weakness is cats, with whom they have a mutual hostility, which can not only see through their illusions, but can inflict severe to fatal wounds upon them with their claws.
