Roy Hess is Earl Sinclair's best friend and co-worker on Dinosaurs. An affable tyrannosaurus rex, usually addressing Earl as "pally boy," Roy is known to Earl's kids as Uncle Roy. Roy is a bachelor, and has a serious crush on Monica DeVertebrae. He also briefly dated Earl's sister, Pearl.

David Greenaway puppeteered Roy's face. Pons Maar, Roy's suit performer, operated the huge head (held high above his own) from inside the suit, using a small monitor to see the outside world. Roy's tiny animatronic arms were operated with an arm-rig by Julianne Buescher.

Roy also occasionally visits to play chess with the Sinclair family.


  • According to the episode "Georgie Must Die," Roy's middle name is "Danger." It was his mother's maiden name, and they wanted to keep it in the family.
  • He dressed up like a girl at least 3 times before. He mentioned dressing up like a USO girl in Nuts to War Part 1 before and again, and dressed up like a woman in Working Girl.
