Leon is a 24-year-old identical twin who is often seen with his twin brother Chuck.
Leon is a green chameleon and twin brother of Chuck. His hobbies include making movies, accidentally tricking people, and owning several stores. He is an employee along with his brother at many O-Town locations. According to himself and his brother, the two once worked for a Czar (who considerably resembled Heffer) in the fictional country of Balzak before immigrating to America. Leon was voiced by Carlos Alazraqui.
Leon is naked most of the time. He is mostly green with blue eyelids and a blue mouth, exactly like his brother Chuck.
