Devon (voiced by Eric Idle) and Cornwall (voiced by Don Rickles) are a two-headed dragon in Jaden's Adventures of Quest for Camelot. They both hate each other and blame each other for not being able to fly or breathe fire. But they both agree to help Jaden and Kayley get to Camelot to help King Arthur.
Trivia
