- This card's left Dragon head has ram-like horns similar to those of some depictions of Satan. Interestingly, unlike similar horns, they were not edited out for the TCG Version of this card's release.
- "Arcana Force EX - The Dark Ruler", "Arcana Force EX - The Light Ruler", "Odin, Father of the Aesir" and "Sephylon, the Ultimate Timelord" are the strongest Fairy-Type monsters in the OCG/TCG.
- Although this is a Dark counterpart to "Arcana Force EX - The Light Ruler", it itself isn't a DARK monster in the TCG/OCG. It was the only Dark counterpart like this until the release of "Dark Desertapir".
