- This card's name is a reference to the fact that Xyz Monsters have black card frames.
- Like the other "Superdoom King" monsters, this monster resembles a final antagonist from another series: Don Thousand, the main antagonist of the Yu-Gi-Oh! ZEXAL anime.
- This monster's horns resemble the Barian Emblem, which symbolizes Barian World, the dimension where Thousand was banished into after Astral World cast out Chaos.
- This monster's tentacles fit Don Thousand's initial form, where he often used tentacles, such as when he trapped Vector.
- Fittingly, this card is also an allusion to the fact that this was the era where Xyz Monsters were played frequently.
