"C", short for and known as "Chaos" (Ｃ（カオス） Kaosu) in the Japanese version, is an archetype of Xyz Monsters supported by the anime effects of the "Rank-Up-Magic" series, and used by various Duelists in the Yu-Gi-Oh! ZEXAL anime. It encompasses two sub-archetypes, "CXyz" and "Number C". Both of those sub-archetypes are explicitly supported by the support cards in the OCG, while the archetypes are combined into this one in the anime.

"Chaos" monsters are all Xyz Summoned by Chaos Xyz Evolution - whether naturally or by a "Rank-Up-Magic" card - by evolving a specific Xyz Monster. When compared to these base counterparts, each of the "Chaos" monsters can be Xyz Summoned normally using 1 more Xyz Material that their original counterpart, but they must be of the corresponding Attribute (for the naturally-evolving "Number Cs") or 1 Level higher (for the remaining "Number Cs" and all of the "CXyzs") than their base form.

Aesthetically there is always a large vortex in the background of a Rank-Up "Chaos" monster. And almost all Ranked-Up monsters have a redish-purple glow emanating from their bodies.

The two sub-categories of "Chaos" monster all share a common weakness with others in their group. For monsters Summoned by a natural Chaos Xyz Evolution, their effects cannot be activated while the controller's Life Points are above 1000. Monsters Summoned by the "Rank-Up-Magic" Spell Cards, however, have two parts to their effects, the second half of which becomes unusable while that monster's specific base counterpart is not attached to it as Xyz Material.
