Number 10X

"Number 10X" (１０Ｘ Nanbāzu Hyaku), former known as "Over-Hundred Numbers" (オーバー・ハンドレッド Ōbā Handoreddo Nanbāzu) in the Japanese version. It is also known as "Number over one Hundred" or "Number over a Hundred" in the dub version, is an archetype of "Number" cards that have numerical values of over one hundred used by the Seven Barian Emperors as their trump card in Yu-Gi-Oh! ZEXAL. Six of the seven base forms are Rank 4, with the last one being Rank 8. The archetype is supported by the effect of "Rank-Up-Magic The Seventh One".

This archetype is somewhat unusual in that the exact string given in the anime effect of "The Seventh One" 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」). Its OCG/TCG effect instead supports each member individually, with the clause "1 "Number" monster from "101" to "107"" (「「Ｎｏ．１０１」～「Ｎｏ．１０７」のいずれかをカード名に含むモンスター１体を」).

Story
In ''Yu-Gi-Oh! ZEXAL'', the "Over-Hundred Numbers" are malignant versions of the "Number" cards designed by Don Thousand to corrupt the Seven Barian Emperors, who have been reincarnated due to each being connected to one of the Number ruins. This suppresses their original memories and allows them to serve him in the restoration of his power. When each of the Barian Emperors was about to die Don Thousand would appear to them and attach each of the "Numbers" to their soul thus filling them with hate. The fake memories (besides Nash, who revealed he let himself become a Barian of his own will) they contain can be countered by the corresponding Mythyrian Number". Unlike the first 100 "Numbers", Astral cannot absorb them since they are not pieces of his memory.

Each "Number 10X" monster has its own Chaos form. The one of "Number 104: Masquerade" is the only Chaos form with a different Attribute than its base form. Also, every Chaos form of each "Number 10X" has a red energy coursing through their being, common among all "C" monsters ranked up through "Barian" Rank-Up spells.

A Barian Emperor whose "Number 10X" was destroyed by its corresponding Mythyrian "Number" and loses in the same Duel, forfeits the ability to play his "Number 10X". Unlike the other Emperors, it is revealed that Nash willingly became a Barian, and as such the curse cannot be undone.
