- This card's name comes from the Egyptian God, Osiris.
- Osiris was also the original Japanese name of "Slifer the Sky Dragon".
- This card's design also reflects the appearance of Osiris, as he is shown to be green skined and has a feather on his crown (which is seen on "Asar's" head).
- This card has a similar effect to "Gravekeeper's Visionary".
- This card is the second strongest non-Xyz "Hieratic" monster; the first is "Hieratic Dragon of Sutekh".
- However, it is the third strongest "Hieratic" monster in general after "Hieratic Sun Dragon Overlord of Heliopolis" and "Hieratic Dragon of Sutekh" (the weakest being "Hieratic Dragon King of Atum").
- The sealed form of this card appears in "Hieratic Seal of Convocation".
- The effect of banishing dragons in the Graveyard may hint at Osiris' position as a god of death and the afterlife.
- The card's background with the moon also evoke the persona of Osiris as a god of death/rebirth.
