Full on friendship!

The Dinobonoids are a group of fictional action figures which Billy likes. They are seen in Fiend is Like Friend Without the "R" and Toys Will Be Toys. It's a parody of Dinosaurcers, or Extreme Dinosaurs.


  • Professor Gaylord (voiced by Quinton Flynn) - a normal human who is the leader of the Dinobonoids. He has four fingers and one thumb on each hand instead of three fingers and one thumb like other cartoon characters like Billy. His hair is brown, he wears a metal glove on one hand, wear robot goggles and wears robot antenae, wears a shirt with the word "LOVE" on it, and wears boots and pants.
  • Tex (voiced by Quinton Flynn in first appearance, Dee Bradley Baker in second) - a mechanical Tyrannosaurus rex. He has turqouise skin, wears robot glasses, has sharp blades on the side of his head, has a metal body, scaly skin with legs and tail, and wears transformers boots.
  • Lazlow (voiced by Greg Eagles in first appearance, Frank Welker in second) - a mechanical Stegosaurus in a floating body. He has purple skin with a spike tail with plates on his back and he is in a floating robot tank.
  • It is unknown if there's other Dinobonoid members. It could be possible that they could be other male and female humans and other mechanical dinosaurs somewhere in Billy's house.
  • Billy's costume as a green Hypsilophodon.
