The Tyrannosaurus appears as the main antagonist of the episode "Much Abu About Something".
He is a large red-skinned tyrannosaurus with darker patterns along his back.
He is ferocious, destructive and hungry, eating anything in his path and harming those who threaten him or get in his way.
The Tyrannosaurus is a dangerous predator who lives in the jungle near the city of Ziggarock. When Aladdin and the others try to get food for Zigarrock, he attacks them but Abu, whose a prophecy said that he is destined to be the liberator of Ziggarock, tries to fight the Tyrannosaurus.
Later, Aladdin imagines a plan to trap the dinosaur. Carpet puts a giant X on the ground, while Genie and Iago place explosives on the boulders above. Then, they go in the jungle to find the Tyrannosaurus, who quickly attacks them. They manage to lure him to the X and Genie detonates the bombs, exploding the boulders who fall on the dinosaur and bury him.
At night, the Tyrannosaurus escapes out from underneath the boulders and climbs the mountain to the city. He encounters a young boy and pursues him, but the boy manages to escape from the dinosaur. Shortly after, the Tyrannosaurus attacks the villages and the group during their feast and devours most of the food. He also accidentally destroys the statue of Abu with his tail. Aladdin and his friends try to distract him while the villagers escape, however the giant beast manages to hit Aladdin with his tail, then he destroys a house and the debris fall on Carpet, trapping him. Genie tries to intervene, but the Tyrannosaurus crushes him with his foot. He then comes toward Aladdin, however Abu suddenly jumps on and blinds the dinosaur with bananas. He also throws fruit at the reptile and manages to lure him to a cliff, and the Tyrannosaurus finally falls to its death, nearly taking Abu with it.
