Vampire dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only "alive" at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with theirs fangs and injecting a venom that kills the baby inside.

Saturn Chaos is a spiritual Vampire. She has a very peculiar way of killing her prey. Usually Vampires would attack their object of thirst and bite, but this female uses her nails to carry and inject venom. After the prey has died, Chaos cuts it's main arteries open and pours the blood into an object resembling a glass. Saturn Chaos does this, because she views her fangs as sacred, and finds them touching the filthy flesh of her prey repulsive.
