McQueen is a man of average to above-average height and medium build. He has the letter "M" shaved on the right side of his forehead.[1] He has a unique feature that his pupils are vertical lines almost akin to the eyes of a cat.

He wears a short-sleeved jean shirt with a tag saying "EDWN" ("EOWN" in the anime) on the front of the collar, and fuzzy pants with a spotted crotch-piece. McQueen also sports numerous belts around his waist and legs, one of which he uses in an attempt to hang himself.
