- This monster appears in the artworks of "Frontline Base", "Centrifugal Field", "Formation Union" and "Dark Contract with the Yamimakai".
- This monster is wearing "Metalsilver Armor".
- This is one of only two monsters that has two different Union monsters designed for its use - the other is "X-Head Cannon", which has identical stats.
- Outside of the "A-to-Z" monsters, this is the only monster that is a Fusion Material Monster for a Fusion Monster ("Dark Blade the Dragon Knight") along with one of its Union monsters ("Pitch-Dark Dragon").
- This card's English flavor text mentions "Dark World". This is a translation error, as its Japanese text instead references "Makai" (闇魔界), which implies that this monster serves "King of Yamimakai".
