YMMV / They Thirst

• Complete Monster:
  • Prince Conrad Vulkan is a vampire who is eternally seventeen and has a giant chip on his shoulder. Arriving in the US, Vulkan turns and corrupts people and sends them to turn and corrupt others. For his meals, Vulkan uses a mentally disturbed serial killer named Roach to commit murder and also bring him living victims. When his vampire hordes are numerous enough, Vulkan has them sweep through entire buildings, killing and turning until Vulkan has an army six hundred thousand strong, with the old and infirm simply being "discarded." Caring nothing for his servants, Vulkan brutally murders one after he decides the man is too old to be of any further use to him. Utterly lacking in morality or restraint, Vulkan is described as a "Black as sin Peter Pan": a Spoiled Brat who has never grown up and wishes to make America his perfect, eternal kingdom with humans extinct or kept as cattle in order to feed his ego.
  • Kobra was an albino biker on a cross-country murder spree, using his Mauser machine gun to mow down entire bars and gangs of people in his path for fun, when he was contacted by Prince Conrad Vulkan to join his legion of evil. Becoming a vampire and given full cognizance and power as Vulkan's military commander, Kobra devours several innocents to turn them into his undead slaves, and uses them to prowl the streets of Los Angeles, turning all in their path who could be useful to Vulkan and killing everyone else. After turning Wes Richard's lover Solange into his vampiric bride, Kobra gleefully parades her zombified form in front of Wes just to taunt him, and tries to execute the young boy Tommy when Kobra finds him inside Vulkan's castle.
• Magnificent Bastard: The Headmaster is the true power behind the vampire prince Conrad Vulkan and his dreams of conquest. A mysterious, ancient being who might well be the Devil himself, the Headmaster educated Vulkan after centuries and teaches him dark sorcery with artifacts to make his conquest easier, masterminding the downfall of most of Los Angelas to the vampires. Advising Vulkan and using him as needed, even as a "favored son", the Headmaster grows frustrated with Vulkan's immaturity and eventually departs when Vulkan denounces him, informing him that the kingdom he holds is solely because of the Headmaster and that Vulkan can only keep it if he is able. He isn't.
