Frank (Cars)

Frank is a character in Cars.

Cars
"Frank is a hard worker. He spends his days in the fields harvesting, threshing, and cleaning grain; then it's off to oversee the tractors' work for the rest of the afternoon. By the end of his long day, Frank is ready to power down for the night and prepare for the early morning ahead. So if you're planning to wake Frank up out of his precious sleep, you'd better have a good reason or a really good escape route."

Frank is a mystery-model red combine harvester that resembles a bull, and is the guardian of the 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). Frank is then seen behind a fence with the tractors watching a drive-in movie in the end credits.

Mater and the Ghostlight
Frank makes a cameo sleeping in the field with the Tractors until Mater wakes him up speeding in front of him with a blue lantern on his hook thinking it was "The Ghostlight".
