Mack

Mack is a 1980s-era Mack Super-Liner truck bearing license plate "RUSTEZ3". A dedicated member of the Rust-eze Medicated Bumper Ointment Team, Mack pulls Lightning McQueen's trailer to his races. After McQueen's entire pit team quits, Mack remains as the rookie racer's only friend. McQueen exhorts Mack to drive through the night to his tiebreaker race with Chick Hicks and Strip Weathers in Los Angeles, California, hoping to reach the venue first and to hang out with the [Dinoco]] team. During the long drive, Mack falls asleep and falls victim to the Delinquent Road Hazards, a group of reckless street racers. The Delinquent Road Hazards knock Mack all over the road, causing one of McQueen's bobble heads to fall off its perch and hit a button, opening his trailer door and dump a sleeping McQueen onto the road. When Mack wakes up, he is unaware that McQueen has gotten lost and has ended up in Radiator Springs. Eventually, Mack travels to Radiator Springs and, under threat of being fired by McQueen's agent,Harv, transports McQueen to Los Angeles. There he serves as McQueen's pit crew until a group of McQueen's friends from Radiator Springs show up to help. After the race, Mack moves to Radiator Springs with McQueen and is shown at Flo's Cafe in the short film Mater and the Ghostlight, as well as in the video game based on the film.
