Series creator Masashi Kishimoto had likened Guy's passionate personality to that of a physical education teacher he had in junior high school, but notes that the teacher was not a model for Guy's character. In the Japanese anime, his voice actor is Masashi Ebara (who also voices Guy's father, Duy), with Masayuki Makiguchi voicing him as a child. In the English anime, Guy is voiced by Skip Stellrecht (except in "Rock Lee and his Ninja Pals", where he is voiced by Matthew Mercer), with Todd Haberkorn voicing him as a child.
