Number 10X

"Over-Hundred Number" (オーバーハンドレッドナンバーズ Ōbā Handoreddo Nanbāzu) is a sub-series of the "Number" cards that go over the limit of 100 mentioned in the first season of Yu-Gi-Oh! ZEXAL anime. They were introduced as the signature cards of the Seven Barian Emperors, which are ranked higher than 100.

Unlike the first 100 "Numbers" however, Astral does not appear to be able to absorb them, since they are not a part of his memories. So far, each member has an effect that negates a monster effect, and each one of these cards has its own counterpart, except for "Number 102: Star Seraph Sentry" so far.

Given the apparent link between the Seven Barian Emperors and the Over-Hundred Numbers (the highest of which is 107), it could be assumed that "Number 101" and "Number 103" correspond to the two missing Barian Emperors (Nasch and Merag), and thus have not been seen. It is perhaps interesting to note that Mizael was the last to 'create' or 'capture' his Over-Hundred Number during the events of Yu-Gi-Oh! ZEXAL II, which leads to a plausible explanation for the lack of "Number 101" and "Number 103", since they may have simply not yet been 'created'/'captured'.

So far, 5 Over Hundred Numbers have been revealed, as well as 5 'Number C' counterparts.
