Card Trivia:Clorless, Chaos King of Dark World
- This is the first and only Dark World Fusion Monster, as well as the first and only Dark World monster that has an effect not shown.
- This is the second Dark World monster to not have an effect that activates when it is discarded: the first is Scarr, Scout of Dark World, and this card inherently cannot be discarded because it cannot be in a player's hand.
- It is one of the three Dark World cards that hasn't been released in a TCG/OCG set. The others are "Cobal, Excavator of Dark World" and "Dark World Corridor".
- This is one of two Fusion Monsters that requires "Super Polymerization" for its Summoning. The other is "Super Fusion God".
- This card shares a name with "Chaos King Archfiend". Ironically, "Chaos King Archfiend" is a Synchro Monster, whose border is white, largely considered the absence of all pigment color.
- However White can also be considered all colors combined (when refered to in terms of light). Being called Darkworld monsters however imply he would be he is Black the "color" you see when seeing no color at all.
