10 Monsters In Buffy The Vampire Slayer That Kept You Up At Night
7. Killer Clown
As a manifestation of Xander's fear in the episode 'Nightmares', Killer Clown was neither a major villain or even the key villain of the episode. This goes to show how creepy this he was though.
At his sixth birthday party, Xander was chased by a clown, planting the seed of this fear to spread into his adult life. Following a horror jump scare, the clown begins chasing Xander through an abandoned part of the hospital with a knife. Buffy has always revelled in horror, but this is one of the moments where show mostly drops the humour and indulges in pure terror. Normally we have Buffy fighting vampires and saving the day, but in this moment Xander is alone and truly terrified.
As an extension of Xander's mind, this villain tapped into a very common and very real fear many people struggle with. Undoubtedly, the scenes with this particular monster may have given a few viewers nightmares of their own.
