Lewis is a very childish cousin of Mater. His number is 81 (20 in Cars:IGNITE and Vince VG).
Cars: The Video Game Edit
Lewis appears in Rustbucket Race-O-Rama, he is not playable.
Cars: Mater-National Championship Edit
Lewis appears in rustbucket races 3 and 4, again unplayable.
Cars:IGNITE Remake Edit
Lewis is under consideration of being playable, the makers of the "Poliwrath Vs. Exploud" fangame plan to model him with a lower chassis and ten exhaust pipes.
Lewis would have been playable if the idea had not been scrapped.
