Card Trivia:Fiendish Knight
- This card is the first and currently non-"Gimmick Puppet" monster used by Quattro in the Yu-Gi-Oh! ZEXAL anime.
- However, since Quattro does not always say the "Gimmick Puppet" portion of his monsters' names, it is possible this monster is actually a "Gimmick Puppet" card.
- In a flashback, Quattro's National Duel Circuit Deck contained "Gravekeeper's Descendant", but he is never seen using it on-screen.
