Cardians are the monsters of the week sent by Alan and Anne to gather energy for their Doom Tree. They are kept inside cards, and can only be summoned by Alan playing a flute; often Ann is asked to pick them out.
Trivia[]
- The term "Cardian" is derived from the words "card" and "guardian".
- In the Japanese version, all of the Cardians were female, but in the dub, Faraion and Vulturos were given male voice actors, and given the "he" pronouns.
