Dinobots
The Dinobots are a group of Transformers who are a sub-group of the Autobots. They are bipedal quasi-sentient robots who transform into forms resembling prehistoric Earth dinosaurs. Wheeljack discovered some dinosaur fossils and decided to create the Dinobots, patterning them after animals of the era. The original three Dinobots are Grimlock - the leader, who takes on the form of a Tyrannosaur, Slag - who takes on the form of a Triceratops, and Sludge - who assumes the form of a Brontosaurus. Their intellect and speech patterns are based on those of an animal and as such, they are predatory creatures with an instinctive primal need to fight. They are also not particularly bright.
