Gort

Gort is an brown-skinned ogre that collects junk in his house, because everything that gets lost in other places (mortal or Halloweentown) ends up in his house. He hates cleaning and everyone he encounters. In the second movie, Kalabar's son Cal casts the Grey Spell on the whole town, turning them into the boring versions of humans, and Gort becomes an opposite version of his true self.
