The Crippler is a hospital monster truck who wanted to challenge Lightning. When Lightning was turned into a monster truck, The Crippler and Ginormous got scared, but Count Spatula said McQueen needed the mental fortitude. McQueen later proved them wrong.
In Cars Race-O-Rama, the Crippler appears in all 5 Monster Truck Races. Even on the PlayStation 2 version of the game, he appears in all 5 races. However, he is not playable in this game either.
The Crippler is painted white, with tailpipes and a siren on his roof. On his doors, he has some sort of a design or word. He also has a black grille, headlights, and hydraulics that connect his chassis to his giant tires.
