Kevin is a blind boy and a student of Springfield Elementary School. Nelson Muntz befriended him.
Nelson put his stuff down on the desk next to him and Kevin knocks it off the desk. Nelson then threatens him, telling him to pick it up. He then gets up with his stick and Nelson realizes that he is blind.
Later, Nelson defends Kevin against anyone who threatens him in any way. Eventually, after the no-touching rule is thrown out, Kevin touches Nelson's face and tells Nelson that he is ugly, resulting in Nelson punching him in the face. Kevin says that he can see again, which Nelson believes until Kevin says "Ha Ha!".
 Behind the Laughter
His appearance is nearly identical to that of Kyle, a student in third grade.
