Machida

Machida is a fictional demon and a one-time antagonist featured on the supernatural action/comedy series Buffy the Vampire Slayer. He was portrayed by Robin Atkin Downes and appeared in the fifth episode of season two, "Reptile Boy".

Biography
Machida was an enormous snake-like demon worshiped by the members of the Delta Zeta Kappa fraternity. He dwelled in a chasm in the basement of the fraternity house and fed on young women, as Buffy Summers and Cordelia Chase experienced. Buffy finally killed him by separating him from his snake-like tail with a ritual sword she aquired from the fratboys.

Machida had a humanoid upper body and a long serpentine tail for a lower body, the full length of which remained inside the chasm and was never exposed. His face, most notably his nostrils, had serpentine features. His mouth appeared to be stretchable, and he had pointed teeth. His body was covered with yellowish-green scales. His arms were webbed to his torso. Machida had clawed fingers.

Machida fed on girls offered as a sacrifice by the fraternity in return for immense wealth and protection. The feeding had a structured cycle—the demon had to be fed on the tenth day of the tenth month every year. Once his followers have secured the sacrifices, they would invoke him to come forth. When Richard tried to abuse a drugged and unconscious Buffy, he was prevented from it by Tom, so this may imply that Machida can only consume virgins.
