Great Brain (voiced by Randy Pearlstein) is a thought-monster with a stem and only one eyeball. He attends Mark Lilly's class at the Department of Social Services.

He claims to have once been the leader of a massive hive dedicated to the propagation of his species (though Mark notes that his file says he's from Toronto), but now works as a house cleaner, using his body, or brain, as a sponge.

His fiancé, Dolores, appears once in the episode "Sympathy for the Devil" but has not been mentioned since.

Episode Appearances[]

Great Brain appears in nearly every episode in the series. The episodes listed below are where he plays a more active role in the story.

Trivia[]

  • Great Brain's appearance is modeled after the monsters in the 1958 movie Fiend Without a Face, which was in turn adapted from the 1930 story "The Thought-Monster" by Amelia Reynolds Long. The difference between Great Brain and the movie monster is that the movie monster has tendrils and a pair of eye stalks.
  • Randall hints that Great Brain is scared of heights, in "Mummy Dearest".
