10 Monsters In Buffy The Vampire Slayer That Kept You Up At Night

10. Bezoar

From Season Two, this giant prehistoric parasite took over Sunnydale High School by hatching hideous eggs. The babies would latch onto humans and take over their motor functions.

This particular monster was somewhat reminiscent of the face-hugger from Alien, and made things much more personal by attacking Buffy's mother and friends. The creature would then drain the life from the host who had become a mindless slave to the Bezoar.

In addition to the eggs, the mother Bezoar was capable of ingesting humans and vampires alike and in the end had to be killed from the inside by Buffy. One of these creatures was hard enough to kill let alone if the babies had grown to their full strength. This was an early - but no less terrifying - monster that crept up on our heroes from beneath their very own school.
