Tyrannosaurus rex

The Tyrannosaurus Rex is the main antagonist in "The Rite of Spring" segment and in Disney's 1940 film Fantasia. Like most non-talking animal villains (such as The Rat from Lady and the Tramp, Glut the Shark from The Little Mermaid, Monstro from Pinocchio, The Bear from The Fox and the Hound, all carnivores from Dinosaur, and Sabor from Tarzan) the T-Rex does not show off that it intends to kill for evil (like a wicked grin or a laugh), helping audiences to understand that it just wanted to eat, which is not a crime for an animal to eat. But it's horrifying looks answers to why it is a villain otherwise.

Appearance
Tyrannosaurus is a huge black dinosaur with a big head an a mouth full of razor-sharp teeth and three large claws.

Role in the film
The Tyrannosaurus attacks the herd of dinosaurs and a Stegosaurus fights it. After a long battle, it gains the upper hand and kills the Stegosaurus by biting it's throat, therefore crushing it. After the Stegosaurus dies, with all the other dinosaurs watching, the Tyrannosaurus roars in victory and then it eats. Near the end of the segment, it dies along with the rest of the dinosaurs do to mass dehydration as the earth climate changes.

Disney Parks
Tyrannosaurus Rex is seen as The Disneyland train travels to the Primeval World diorama. In it, it is seen reenacting his battle from Fantasia.

In Real Life
In real life, Tyrannosaurus lived in the late Cretaceous Period 68-65 million years ago. Thus, it did not coexist with Stegosaurus, which lived in the Jurassic Period from 150-145 million years ago. Unlike in Fantasia, it did not have three fingers; it had two. Why it had three fingers is because Walt Disney reported to Barnum Brown, the discoverer of Tyrannosaurus, that it looked better that way.
