 * The new artwork of this card in the Anniversary Pack features it with a new look similar to the Bandai style; it appears with red skin, no eyes, larger un-horned wings, five-fingered claws (as opposed to its three-clawed hands featured in the anime and the artwork of "Skull Archfiend of Lightning"), bony feet, a tail, and a scythe as its weapon (not featured in previous artworks).


 * According to Master Guide 1, the alternate artwork of this card released at the Third National Conference in Japan qualifies as the rarest card ever released, as well as the other alternate artwork promotional cards released at that same conference.
