Kyle is a third- then fourth-grade student who commonly has extraordinary experiences not typical of conventional small-town life in his fictional hometown of South Park, Colorado.

His portrayal in this role is often dealt with satirically, and has elicited both praise and criticism from Jewish viewers.

Kyle is animated by computer in a way to emulate the show's original method of cutout animation. He also appears in South Park: Bigger, Longer & Uncut, the 1999 full-length feature film based on the series, as well as South Park-related media and merchandise. While Parker and Stone portray Kyle as having common childlike tendencies, his dialogue is often intended to reflect stances and views on more adult-oriented issues, and has been frequently cited in numerous publications by experts in the fields of politics, religion, pop culture, and philosophy.
