- This is the very first (Warrior) monster played in the first episode of the Yu-Gi-Oh! anime by Joey Wheeler, making it the first card ever played in any series of Yu-Gi-Oh, besides the Toei anime.
- This card's TCG and Korean names suffer from a mistranslation: "Blue Flame" is a translation of "Shien" (literally "purple flame"), and kagemusha means "body double", making this monster "Shien's Body Double", and therefore affiliated with the "Six Samurai". This error occurred because this card was release long before the introduction of "Shien".
- This monster has a counterpart (or possibly a later form) in "Kagemusha of the Six Samurai". They both share the same color clothing and hair, as well as being a mirror image in posture.
- This monster appears in the artwork of "Unification", albeit with a different color palette.
