What is the most dangerous vampire?

* The least dangerous vampire would be one that carefully regulates his consumption and only uses dependent thralls. This type of vampire could potentially be a positive influence to his community. * Next most dangerous vampire would be one that didn't have a supporting community but would have to hunt for his blood sources. If he was still carefully regulatory he wouldn't have a serious detrimental effect on his community but the situation might get out of control, retributions might be attempted and then the vampire would have to fight for his life, which could get ugly. * Next would be an unsupported vampire that didn't regulate his consumption and seriously injured or killed people in his predations. * A psychic-vampire that could 'kill from a distance', harder to destroy. * A non-corporeal psychic vampire (without a body, incubus and succubus), again even harder to destroy. * A reproducing vampire (of the three gradations already mentioned). If there's more of them they become more dangerous. * A reproducing vampire who takes care to produce higher quality 'offspring'. Quality and quantity together is a powerful combination. * A vampire who is also a powerful sorcerer, shape-shifting, mesmerizing, etc. If he also reproduced and had devoted minions He would be Count Dracula. * A vampire who also is a plague carrier (Nosferatu) such as Count Orlock.
