Bartles is a 6th grade boy who attends South Park Elementary. He was unnamed until the Season Twelve episode, "Britney's New Look"; he was later renamed Bartles in South Park: The Fractured But Whole. He first appeared as part of the group of 6th graders who were riding their bikes when The Boys asked them for protection against Trent Boyett. He along with the rest of his 6th grade friends were unsuccessful in fending off Trent Boyett. They ended up in the hospital with minor injuries, such as Indian sunburns and titty twisters.
