Devon and Cornwall are the tritagonists of Quest for Camelot. They are one of Kayley's best friends.
They are conjoined dragons, with Devon being a tall, thin, slim dragon whilst Cornwall is a short, fat dragon.
Devon and Cornwall hate each other so much that they even sing a comical song about not having each other ("If I Didn't Have You"). However, they cry upon hearing "Looking Through Your Eyes." Eventually, they are able to overcome their differences.
When flying their human friends, they even talk like airline pilots.
- John Cleese and Rowan Atkinson were considered for the role of Devon and Dennis Miller and Steve Martin were considered for the role of Cornwall.
