Badassasaurus is a machine, with the appearance of a half-track vehicle modeled after a tyrannosaurus rex, piloted by Piston. It is a formidable opponent, with resilient structure and a number of devastating attacks.
Badassasaurus is used by Piston to maintain control of his No. #1 ranking in the Torgue Arena with an unfair advantage. However, the Vault Hunters managed to destroy it and Piston is forced to fight them without it.
