Devon and Cornwall are the tritagonists of Quest for Camelot. They are conjoined dragons with Devon being a tall, thin, slim dragon whilst Cornwall is a short, fat dragon. Devon is voiced by Eric Idle, and Cornwall is voiced by Don Rickles.
They don't like each other and wish for individual parts so they can handle things on their own. Unlike other dragons they cannot fly or breath fire thus making them outcasts among the other dragons. They join Kayley and Garrett on their quest to find Excalibur. In the end, Devon and Cornwall are briefly separated, but decide to stay as one after they worked together after Ruber was stuck in the stone with Excalibur in his hand and got destroyed.
