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.
The code was created as the result of a tear shed by the dragon that created the universe impacting with Earth. This also created the moon, where the key to the Code ended up. The correlation between these events was inscribed on a tablet.
Finding the Code is the primary objective of both the Barian and Astral Worlds. Each aims to find the Code in order to destroy the other. As seven specific "Numbers" can aide in finding the Code, each world's desire for the Code often takes the form of collecting the "Numbers". In addition, the tablet details that the two "Galaxy-Eyes" dragons must meet on the Moon and battle. The victor will be awarded the key to the Code.
After Yuma Tsukumo and Astral's Duel with Shadow Giant where The Door allowed Yuma Tsukumo and Astral to access more of Astral's memories, they 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 "Mythyrian Numbers" he has yet to collect. Astral intends to use it in order to find the locations of uncollected "Number" cards.
The 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. The "Numeron" archetype is related to the Code and emulates its powers.
After his last Duel with Yuma, Astral finally obtained access to the Numeron Code and used its powers to revive Kite Tenjo, the Seven Barian Emperors, Ponta and Eliphas in order to restore peace to Earth. According to Eliphas, Astral fused the Barian World and Astral World using the reality warping artifact. This also allowed Chaos to return, causing upcoming challenges to take place.
