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.
He has large ears, light-brown, messy hair, and is slightly overweight. He wears an orange and blue striped shirt and blue jeans of the same color as the ones that the 6th grade leader wears. He can be seen riding a yellow bicycle.
