Rex's evil personality

Rex is a giant Tyrannosaurus dinosaur and the leader of a dinosaur gang, including Woog the Triceraton, Elsa the Pteranodon and Dweeb the Parasaurolophus. The main protagonist in the animated movie, We're Back! A Dinosaur's Story, Rex was a former savage beast, before he would gain intellegence from a "Brain Grain", fed up from an alien species, resulting in becoming a good-heart dinosaur. Rex and his friends start their adventure, after the alien species transport them in the 20th century to New York City. There, he makes a fast friendship with the two unexperienced, though friendly, children, Louie and Cecilia. Despite his overall change, Rex has to find his own courage to overpower the forces of evil, including the notorious ringmaster, Professor Screweyes.
