"Number 10X" (Ｎｏ．（ナンバーズ）１０Ｘ Nanbāzu Hyaku), read as "Over-Hundred Numbers" (オーバー・ハンドレッドＮｏ．（ナンバーズ） Ōbā Handoreddo Nanbāzu) in the Japanese version and as "Number Over One Hundred" or "Number Over a Hundred" in the dub, is a sub-archetype of the "Number" archetype used by the Seven Barian Emperors as their signature cards in Yu-Gi-Oh! ZEXAL. Six of the seven base forms are Rank 4, while the last one is Rank 8. The archetype is primarily supported by the effect of "Rank-Up-Magic - The Seventh One". Each "Number 10X" monster has its own Chaos form.
