- This card was the first Ritual Monster to be Summoned during the second series anime, as well as being the first Ritual Monster to be Summoned by Yugi Muto.
- This card has four retrained counterparts (three Effect and one Ritual): "Black Luster Soldier - Envoy of the Beginning", "Black Luster Soldier - Envoy of the Twilight", "Black Luster Soldier - Sacred Soldier", and "Black Luster Soldier - Super Soldier".
- The Japanese version name "Chaos Soldier" comes from its original manga and anime appearance in which a LIGHT and DARK monster were necessary sacrifices to perform the "Black Luster Ritual". The LIGHT and DARK souls created a "gateway to chaos" which "Gaia The Fierce Knight" charged through to become "Black Luster Soldier".
- In most video game texts and in this card's Normal Monster counterpart's lore, this card is stated to have power equivalent to that of the "Blue-Eyes White Dragon", most likely due to the fact that its ATK, DEF and Level equal that of "Blue-Eyes White Dragon".
- Interestingly, unlike "Dark Magician", which had counterparts in other series for being the signature card of a main protagonist, Yugi Muto, this card does not have any counterparts as there has yet to be a main protagonist after Yugi who uses a 3000 ATK monster as their secondary ace.
- This was one of the very few cards not to have an 8-digit input code in the bottom left corner until its reprint in Legendary Collection 3: Yugi's World Mega Pack.
- Its reprint in Duelist Pack: Battle City lacks this code though.
- Pharaoh Atem probably carried the spirit of this card, as he became "Black Luster Soldier" and fused with Seto Kaiba's "Blue-Eyes Ultimate Dragon" to form "Dragon Master Knight" in the fight with Zorc Necrophades.
- This card appears in the artwork of “Draw of Fate”.
