Trivia Edit

  • Rex is not named after his species, Tyrannosaurus rex, but rather he is named after the Toy Story character Rex.
  • Rex was first thought to be Bloodtooth's mate until season 3, where it was revealed that Grant was Bloodtooth's mate.
  • He appears to be the least popular member of the Tyrannosaurus Pack as very few fans were upset with his death.
  • Because Rex died in the same episode as his nephew Little Tyrant, Rex's death was subsequently overshadowed, as Tyrant had more of a following than his uncle before their subsequent demises.
