Slake

Slake was a human who was turned into a vampire in the 1950s. In 1997, he tried to turn an otherwise dormant sect of vampires into a domineering cult, fit to rule over mankind. He was killed after he fed on the Eighth Doctor's blood which was infused with a vampire killing solution. (PROSE: Vampire Science)

Personality
Although Slake was turned in the 1950s, he still had the rebellious streak of a young man. He showed little respect, bordering on contempt, for his elders. Slake was narcissistic and impatient when things weren't in his favour. He saw humans as food and nothing more, and enjoyed terrorising people, including Samantha Jones. (PROSE: Vampire Science)
