"Number C10X" (Ｃ（カオス）Ｎｏ．（ナンバーズ）１０Ｘ Kaosu Nanbāzu Hyaku), short for "Over-Hundred Chaos Number", is a sub-archetype to both the "Number 10X" and "Number C" archetype, used by the Emperors of Barian World. Each Chaos version of them seems to have a red aura inside of their body. In anime, most of them were first summoned by Ranking-Up the corresponding "Number 10X" using "Rank-Up-Magic Barian's Force". After Nasch and Merag got their memories back, the Barian Emperors were supplied by "Rank-Up-Magic - The Seventh One", allowing a very easy summon (from Graveyard or Extra Deck). However, the first support card was "Chaos Mad Feast". The usual tactic of "Number C10X" is to negate their opponent's effects and/or deal a lot of damage (helpful in the anime due to the effects of Yuma's "Number 39: Utopia", Vector's "Number 43: Manipulator of Souls" and Kite's "Galaxy-Eyes Photon Dragon"). These can be used to summon CXyz Barian.

This archetype is somewhat unusual in that the exact string given in the effect of "Chaos Mad Feast" doesn't actually appear in the names of any members; instead it has the clause "X is any number from 1 to 7" (「Ｘは１～７の任意の数値」).

Weakness

Like most Rank-Up Chaos Numbers, they can't activate some of their effects if their base forms were not attached to them, expect for Silent Honor Dark and Ragna Infinity since don't need their base forms attached to them in order to used their effects. However, if you don't have Silent Honor Ark and Regna Zero in the Graveyard or their Chaos versions has no Xyz Material, they can't be revive from the Graveyard. If you don't have any of the Number 10X that has the same number as their Chaos version in your Extra Deck, on Field, or in your Graveyard, your can't use Rank-Up Magic The Seventh One to summon their Chaos version.
