Goryu

Goryu is the leader of the Dinoforce and once loyal subordinate to Deathsaurus, leader of the Decepticons; he is a Pretender with a Tyrannosaurus Rex like shell that he often rides into battle while wielding a spiked club.

Goryu eventually turned against his master after being abandoned on Earth, and after helping Star Saber's Autobots sabotage his space fortress led his team in construction efforts on Earth in payment for their previous misdeeds.

Trivia
