Colorless, Chaos King of Dark World

DARK/Level 12/Fiend/Fusion/Effect/ATK 3600/DEF 3600

"Reign-Beaux, Overlord of Dark World" + "Dark World" Cards

Cannot be Special Summoned except with "Super Polymerization" or a "Super""Fusion" card. When Fusion Summoning this card, you can also use Spell/Trap cards among the material. While this Fusion Summoned card is face-up on the field, this card is unaffected by cards/effects of types (Monster, Spell, Trap) used for the Fusion Summon and deals piercing damage, also all other monsters lose original ATK equal to the original levels of each differently named Dark World Fusion Material used that is not specifically listed x 100. This card gains ATK equal to the highest original ATK amounts lost this way among all differently named face-up "Dark World" monsters you control (except "Reign-Beaux, Overlord of Dark World").

This card was seen, but not used, in Yu-Gi-Oh! GX. Its effect was not revealed.
