Card Trivia

 This is the first Rank 12 Number monster to be revealed.
This is the first revealed Number to have a number with more than three digits.
Its number is a reference to Don Thousand's name.
This is the second Number C monster to so far not have a base Number form.
This is the first Number C monster in the anime to be Summoned without using Xyz Evolution.
This card appears in the artwork of Numeron Storm.
This card can be considered similar to Vennominon the King of Poisonous Snakes:
Both are the weaker of two ace monsters for a certain archetype (Numeron and Venom), while not actually belonging to that archetype thanks to a slight alternation in the card name.
Both, when destroyed, can Summon a stronger ace monster that possesses an automatic win condition.
