Card Trivia:Clorless, Chaos King of Dark World
- This monster's appearance resembles a statue of Buddha.
- Fittingly, in the Yu-Gi-Oh! GX anime, this monster was intended to be Summoned through the effect of "Wicked Canon", which is named similarly to the Japanese term for the Buddhist texts.
- This is the first "Dark World" Fusion Monster, as well as the first "Dark World" monster that has an effect not shown; however, this is the second "Dark World" Fusion Monster to be released in the OCG/TCG.
- This is one of two Fusion Monsters that requires "Super Polymerization" for its Summoning in the anime, the other being "Super Fusion God".
- Both are also Fusion Monsters that were mentioned but never actually seen in the Yu-Gi-Oh! GX anime.
- Despite its name, the only solid color depicted in this card's artwork is the color black, while also featuring faint colors of the rainbow. In a RGB color model, the color black is made up of all colors and creates the absence of white, which is made up of all colors.
- Fittingly, this monster requires "Reign-Beaux, Overlord of Dark World" as Fusion Material, and the "Dark World" archetype consists of Fiend monsters whose names are based on a different color, which would make up all the colors to create the color black.
- This monster's OCG/TCG Fusion Materials are based on a scene in Yu-Gi-Oh! GX episode 136: "Turning the Page, Part 2". After Brron, Mad King of Dark World failed to Fusion Summon this card, he controlled "Reign-Beaux, Overlord of Dark World" and "Zure, Knight of Dark World" at the end of the turn, while Jaden Yuki controlled two "Dark Tokens" (a Fiend Token) Special Summoned by the effect of Brron's "Darkness Half".
