• The three eyes of "Yubel" may be a reference to the three heads of Dante Alighieri's Satan in the Divine Comedy. Both are considered traitors to their lords and have taken the form of a dragon as a primary form of combat at one point in their lives. This is further elaborated on in "Yubel - The Ultimate Nightmare", who is depicted with three heads akin to Satan.
  • The effect of "Yubel" ties in perfectly with the character's sadomasochism: whatever 'pain' (i.e. battle damage) this card experiences, it reciprocates the opponent in Life Point damage.
    • This goes along with how in the anime, despite Yubel using herself and her evolutions to attack Jaden's monsters, it is depicted that the monsters are forced to instead attack her while she simply takes the attack.
  • "Yubel" sounds like "Jubel", the German word for "exultation".
  • This card is one of few (if any) cards whose artwork was censored from the anime to the OCG. Despite this, it was not censored from the OCG to the TCG, but it was censored between the original anime and the dub.
