Quetzal, portrayed by Eli Gabay, is an elderly dragon who is the teacher at The School in the Sky where young dragons attend. He has an identical twin brother named Fernando who works in his garden. Quetzal typically speaks with a Mexican accent and is likely named for the Aztec deity Quetzalcoatl. He tries to encourage his young charges to find solutions to their problems on their own, but is a sounding board who offers stability and comfort, as well as sound advice. In the episode 'Snow Dragon,' Quetzal mentions it has been hundreds of years since he visited the dragon snow sculpture as a child, implying he is centuries old.
