Vampire (mythology)
Vampires were mythical creatures that were feared for their dependence on sucking the blood of other beings to survive. One of their common names was Nosferatu. (COMIC: The Swords of Kali) A wide variety of other lifeforms shared traits with these creatures and either inspired or made use of the legends.
Legends
The Doctor's TARDIS had records of vampire legends on at least seventeen planets, particularly Earth, but myths of vampires existed on almost every civilised world. Common traits were that they drank blood, could turn others into vampires, feared sunlight, had no reflections, feared crosses, couldn't cross running water and could only be killed by a stake to the heart or beheading. They could supposedly only enter a room or house upon being invited, which was why they were so charming. (TV: State of Decay, The Vampires of Venice, PROSE: Goth Opera, AUDIO: Son of the Dragon, WC: Monster File: Vampires) Vlad III was thought by the people of Wallachia to be a monster, which lead to a popular fictional representation of him; (AUDIO: Son of the Dragon) although the popular fictional Count Dracula was also a real person. (PROSE: The Dreadful Flap, The Found World)
