Harlequin Demon is a citizen of Halloween Town.


He is a monster who has many sharp teeth and three black and orange tentacles on his head.

Harlequin Demon is based on an evil spirit named Beelzabub.


Harlequin Demon, like the rest of the residents of Halloween Town, loves to scare others and take part in big events and help out in their preparation. Due to being a monster, he has no trouble with frightening and disgusting things and gladly enjoys messing around with dead animals corpses, however he has very little understanding of nice and pretty things due to being a resident of Halloween Town. He also seems to be skilled at turning rotting animal corpses into wearable hats, even considering himself a genius regarding this task.

The Nightmare Before ChristmasEdit

During the song This is Halloween he is hiding in the trash can and in the center of town during the festivities that happened after the song. During the preparations for Christmas, he made hats made from dead rats and bats, Making Christmas. He lastly appears at the end of the movie when all of the creatures are confused by the Christmas snow.


  • On the free online building game 'Roblox,' a hat entitled 'Halloween Monster' was released. It is essentially the Harlequin Demon's upper head, with the eyes and tentacles Nergal from The Grim Adventures of Billy and Mandy Black Mutant Monster Demon Pain and Panic From Hercules Purple and Green.
  • Looking at simply his face, he looks very similar to The Monster Under the Bed.
  • Tentacles and scales it resembles Cthulhu.
