Card Trivia:Rainbow Dark Dragon


 * "Rainbow Dark Dragon" is featured on the artwork of "Advanced Dark" and "Rainbow Gravity".


 * This card is the "Dark counterpart" of "Rainbow Dragon".


 * This card is supported by "Rainbow Gravity" and "Rainbow Path," and can also be fused into "Rainbow Neos" as well as its original version can. Despite all this, however, it cannot actually be used in a normal Crystal Beast deck since none of the Crystal Beasts happen to be DARK attribute.  It is likely that at some point, a legal version of Advanced Dark would have been released that would have allowed Crystal Beasts to count as DARK monsters while in the Graveyard, but this never occurred.
