Vampires are described as being dead and not needing oxygen. They have a pale appearance and are afraid of crosses as sunlight can burn or kill them. They sleep in coffins or upside down like bats, have claw-like fingernails and long canines for biting victims. Some can fly and have very pale skin from little blood in their veins. They need to drink blood to survive but have limited powers during daylight hours. Vampires also have no reflection in mirrors and target victims' necks.
