The two "Numeron" Spell Cards that Yuma uses focus on Xyz Evolution, being used to Summon "Number C39: Utopia Ray Victory" and "Number 39: Utopia Roots". He also has "Number 100: Numeron Dragon", after obtaining it from Mizar.
The cards that Don Thousand uses mainly revolve around activating during the opponent's turn from the hand or even the Deck, and are described as holding the power of the Numeron Code, being able to "rewrite" the opponent's cards and increase their own ATK to extremely high levels.
The "Numeronius" archetype can be considered an upgrade to this archetype, containing related monsters with even higher ATK and stronger effects.
