Card Trivia:Dark Guardian
- This card appears in the original anime artwork of "Montage Dragon".
- This monster is an upgraded form of "Gate Guardian".
- This monster's OCG/TCG archetype condition and alternate Summoning condition by shuffling "Sanga of the Thunder", "Kazejin" and "Suijin" into the Deck is based on how this monster requires "Gate Guardian" to be in the Graveyard in order to be Summoned in the anime.
- This monster's OCG/TCG effect allows it to become immune to activated monster and Spell effects if Summoned by "Dark Element", but not Trap Card effects, referencing the fact that in Yu-Gi-Oh! GX episode 11: "Tag Team Trial, Part 2", the only Trap Card that was used against it was "Hero Barrier".
