Cletus is Mater's oldest cousin, he has the voice and actions of an angel hunter rather than a derbist. His number is 6.
Cars: The Video Game Edit
Cletus competes in Rustbucket Race-O-Rama, not playable.
Cars: Mater-National Championship Edit
Cletus again isn't playable, he competes in rustbucket races 1, 2, and 4.
Cars:IGNITE Remake Edit
Cletus is being planned to be playable, they plan to adjust him with a bigger grille, but smaller number boards.
Cletus was to be playable, but still needed a corresponding engine sound due to that in this game, he would be powered by four SCRAMjets instead of a normal car engine.
