Card Trivia:King of Yamimakai
- The "Yamimakai" in this card's TCG name is translated from the Japanese "Dark Demon World", thus making the direct translation of his Japanese name, "King of Dark Demon World".
- This card is one of the few monsters whose ATK or DEF is not divisible by 50. Others include "Castle of Dark Illusions", "Sword Arm of Dragon", "Dark Chimera", "Reaper of the Cards", "Barox", and "Number S39: Utopia Prime". Notably, PaniK had all of these cards in his Deck (except for "Number S39: Utopia Prime" (who was used by Yuma Tsukumo) and "Sword Arm of Dragon"), and they were all present in his Duel with Yugi Muto.
