Lightning McQueen's third former crew chief
Chuck was the third acting crew chief of Lightning McQueen's racing team, before he was fired due to Lightning's preference of being a "one-man show". Chuck was critical and somewhat inspirational, as he was known to hate McQueen's lack of road racing knowledge.
Chuck is a red Hummer H3.
Chuck makes a physical appearance in a Boom! Studios Comics issue where he is shown to be McQueen's former crew chief.
