"Numeronius" (ヌメロニアス, Numeroniasu) is an archetype used by Don Thousand in the Yu-Gi-Oh! ZEXAL anime. It can be considered an upgrade to the "Numeron" archetype, containing its two ace monsters. It is not a sub-archetype of the "Numeron" archetype, as its Japanese name does not contain 「ヌメロン」.

The archetype focuses on obtaining ridiculously high ATK values (like the "Numeron" monsters) as well as effects that protect themselves and limit the opponent's actions. The only support card specifically for this archetype is "Numeron Storm".

The two monsters in this archetype can be compared to "Vennominon the King of Poisonous Snakes" and "Vennominaga the Deity of Poisonous Snakes", who are also the two ace monsters of a certain archetype ("Venom") yet do not belong to that archetype due to a slight alteration in the card's (Japanese) name. In both cases, the stronger of the two monsters possesses an automatic win condition, and can only be Summoned after the weaker one is destroyed.


  • The two monsters in this archetype are the only monsters to have a printed original ATK/DEF number with more than four digits.
  • In the English dubbed anime, Don Thousand pronounces this archetype's name with a long o sound, perhaps to differentiate or emphasize that it is not a sub-archetype of the "Numeron" archetype.
