This card is the only "Supreme King Dragon" counterpart to one of the "Four Dimension Dragons" to not be Summoned by its own effect. Because of this, it is also the only counterpart to not have a Summon chant spoken onscreen, as well as the only "Supreme King Dragon" not to have its own main focus episode.
This card is shown to have an extra mouth on its chest in the anime (when it activates its effect-stealing effect).
This card's anime incarnation is the first Fusion Monster that can Fusion Summon itself.
This card is the only "Supreme King Dragon" monster that cannot be Special Summoned by the effect of "Supreme King Z-ARC".
