Numeron Code

The Numeron Code (ヌメロンコード Numeron Kōdo) is a powerful card which created all of reality in the Yu-Gi-Oh! ZEXAL anime. It has records of everything in the universe and has the power to decide the fate of all reality.

Story
Numeron Code first appeared after Yuma Tsukumo and Astral's Duel with Shadow Giant whereas The Door allowed Yuma Tsukumo and Astral to access more of Astral's memories. They then learned that Astral's original mission was to find the Numeron Code - the "God Card" that created the world and can decide fate. He must find it before the Barians do. He also learned that the location of the code was hidden in the memories of the 7 "Legendary Numbers" he has yet to collect. Astral intends to use it in order to find the locations of uncollected Number cards.

Numeron Code is shown to be a card that swirls around into different forms in Astral's memories. Inside it is how the world developed and where it is heading to. This card has two Duel Monsters card versions called, "Rank-Up-Magic Numeron Force" and "Rank-Down-Magic Numeron Fall". Later on, Yuma left for Astral World using a Dimensional Transporter to find a way to bring back Astral and search for the "Numeron Code" despite the tribulations involved.

Kite Tenjo stated that the 'Galaxy-Eyes' are related to Numeron Code, how to control it and must have the proper cards to use it.
