(This card is always treated as an "Ultimate Crystal" card.)
Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand or GY) by banishing 8 DARK monsters with different names from your field and/or GY, except "Rainbow Netherdragon", including 1 “Ultimate Crystal” monster. Unaffected by other cards' effects. Once per turn (Quick Effect): You can target 1 monster on the field, then apply 1 of these effects.
● That target gains 200 ATK for each of your banished DARK monsters.
● That target's effects are negated, also banish it during the End Phase.
This was originally a remake of "Rainbow Drak Dragon" that I decided to give it its own body. So if you did not catch it already, it is supposed to be the DARK counterpart of "Rainbow Overdragon" and the retrained version of "Rainbow Dark Dragon". It can be SS from GY to synergize with its Attribute engines, has a great immunity, and can either boost ATK OR a disturb your opponent. Basically, it is the only "Ultimate Crystal" monster that is worth it.
