The Sixth Grader Leader, previously the 5th grade leader, is the leader of the Sixth Graders. Although he is the most prominently featured Sixth Grader, his name has yet to be revealed.
He wears a green T-shirt with a picture of his own face on it and blue jeans. He has a big, slightly bulbous nose. He also has messy brown hair and large sideburns. His eyes have a unique shape.
His main interests include doing sweet wheelies on his bike, picking on younger students, and acquiring pictures of breasts and other pornographic material. He appears to never have actually seen a real pair of breasts since he appears unable to discern the difference between Cartman's ass and a pair of breasts in "Pre-School".
