We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.
This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Yugi Muto — The entry states that Yugi learns his alter-ego is a Pharaoh named Atem from Ishizu immediately after the Duelist Kingdom arc, but in the manga this revelation occurs during the Battle City arc.
Yugi Muto — The entry claims Yugi defeated hunters to collect all three Egyptian God Cards, but he only obtained Slifer from a hunter; Obelisk was given by Kaiba, and Ra was obtained through other means.
Chazz Princeton — Chazz Princeton is not a primary antagonist; he is introduced as a rival and later becomes an ally, but the main antagonist of early GX is Seto Kaiba (briefly) or more accurately, characters like Dr. Crowler or the Shadow Riders, not Chazz himself.
Aster Phoenix — Aster Phoenix is from the United States, not the United Kingdom, in the original Japanese canon.
Aster Phoenix — Aster's initial motivation is revenge against the Light of Destruction, but the Light of Destruction is not a character he personally seeks revenge against; his revenge is specifically against the Duelist who caused his father's death.
Seto Kaiba — The claim that Obelisk the Tormentor was an authentic ancient Egyptian artifact, not a scientific replica, is incorrect. In the canon, Kaiba's version in Battle City was a replica created by Kaiba Corporation using data from the original card; it was not an au
Seto Kaiba — The claim that Kaiba never faced the Shadow Riders is incorrect. In the Yu-Gi-Oh! GX anime, Kaiba did face and defeat one of the Shadow Riders off-screen.
Kaiba Corporation — The original prototype of the Duel Disk was personally built by Seto Kaiba, but later versions were developed by KaibaCorp engineers under his supervision.
Barians — The claim that Kite Tenjo is the human host of the seventh Barian Emperor Regulus is incorrect; the seventh Barian Emperor is Dumon/Durbe with host Reginald 'Shark' Kastle, and Kite Tenjo is the host of the sixth Barian Emperor Mizar/Mizael.
Barians — The claim that Regulus is a Barian Emperor is incorrect; the name 'Regulus' does not appear in Yu-Gi-Oh! ZEXAL canon as a Barian Emperor, and the correct list of Barian Emperors does not include Regulus.
The Pharaoh Atem — It was Yugi Moto who spoke Atem's true name aloud during the final duel, not Atem himself.
The Pharaoh Atem — Atem's true name was inscribed on the inside of the Millennium Puzzle, not the back.
The Millennium Items — The entry claims the items were 'not originally to seal away any specific entity' and 'not originally to seal Zorc Necrophades,' but in canon, the items were indeed created specifically to seal Zorc Necrophades.
The Millennium Items — The entry says the Millennium Puzzle 'housed only one additional spirit' besides Atem, but canon shows the Puzzle contained the spirits of Atem and the six other Pharaoh's Guardians (the priests).
