|Appearances||Mr. Torgue's Campaign of Carnage|
Badassasaurus is a machine, with the appearance of a mechanical tyrannosaurus rex, piloted by Piston. It is a formidable opponent, with resilient structure and a number of devastating attacks.
Badassasaurus is a gigantic robotic vehicle used by Piston to maintain control of his No. #1 ranking in the Torgue Arena. Frequently called a "coward" by other competitors, he vehemently denies the allegation, and yet when the Vault Hunters stand poised to oust him from his leading position he unveils the Badassasaurus to give himself overwhelmingly unfair advantage.
