Films: The Devil Master (1977)
Location: Haunted home
Height/Weight: That of an average human.
Summary: Cults won't get you friends, only enemies and subordinates. And who really wants that?! Well, Laval certainly did.
History: Laval Blessing (sigh...yes) was a very bitter cultist demanding that everyone think like him and uphold the rules of the kingdom of darkness. In retaliation for his "suffering", he enlisted the help of a powerful arch-demon to grant him power. Although reluctant at first due to the sheer pettiness of the situation, the demon complied.
Notable Kills: Nothing special.
Final Fate: Eventually, the demon decides to end it all by killing Laval himself after most of the visitors/cultists are dead. He's then shot, causing him to leave for Hell, but not before telling the man that he would meet him there.
Powers/Abilities: Mind warping, nigh-invulnerability, and twin sais for weapons.
Weakness: Killing him the conventional way will send him back to Hell.
Scariness Factor: 3-Many things hold this otherwise intimidating demon back. But most specifically his voice. It sounds like Skeletor high on mushrooms, really.
Trivia: -The Demon was played by David J. Howard, who would go on to do literally nothing else. Bummer.
-This film is also known as "The Demon Lover".
