• As "Red-Eyes Black Metal Dragon" is a metalized version of "Red-Eyes Black Dragon", this card is a metalized version of "Red-Eyes Darkness Dragon" and as such has the same ATK and DEF as "Black Metal Dragon", which ties them for having the highest original ATK and DEF of all "Red-Eyes" monsters.
    • Unlike "Black Metal Dragon", this monster is a Dragon instead of a Machine.
    • Also unlike other "Red-Eyes" monsters, the printed version of this card's only direct relation to them is it's name and image (since the requirement of a "Red-Eyes" to Summon it was completely removed, rather than altered).
  • This card has the highest Level of all "Red-Eyes" monsters.
  • This is the first "Red-Eyes" monster to become Limited.
