The Sixth Grader Leader (previously 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 never to have actually seen a real pair of breasts, however, since he appears unable to discern the difference between Cartman's ass and a pair of breasts in "Pre-School".
He apparently finds Mrs. Marsh attractive, as in "Pre-School", he promised that his gang would defend the boys from Trent Boyett in exchange for a picture of her breasts. Obviously, this is an entirely one-sided physical attraction.
Social Standing in General
He often assumes the position of leadership within the Sixth Grade. It is assumed he has a high status within the Sixth Grade social hierarchy. He appears to have a low opinion of Fourth Graders, whom he greatly enjoys tormenting. In "Toilet Paper" he is seen in Juvenile Hall. This may indicate that he is a trouble maker.
