The Krelboynes are a group of gifted students at Malcolm's school. About six Krelboynes make recurring appearances. They have a hard time making non-Krelboyne friends because of their almost nonexistent popularity, and social problems. Malcolm is often called the coolest of the Krelboyne kids. Despite there being many female Krelboynes in the class, only one makes recurring speaking appearances.
