Frank is a character and a minor antagonist in Cars and secondary antagonist of Mater and the Ghostlight.
He is a mystery-model red combine harvester that resembles a bull, and the guardian of his tractors. After Lightning McQueen and Mater woke him by scaring the tractors, he chases them out of the field. Soon, Lightning has a nightmare that he, The King, and Chick Hicks are beaten by Frank in the tie-breaker race, with Chick Hicks not even surviving the race (Frank catches him, shreds him, and expels his remains from his unloading auger). Then, Frank is seen behind a fence with the tractors watching a drive-in movie in the credits.
