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.

Bowser — The claim that Jack Black voiced Bowser in 'The Super Mario Galaxy Movie (2026)' is an invented claim; no such movie has been announced or released in the established canon.
Bowser — The statement that Bowser's original working name was 'Boss Creeper' is incorrect; the original working name was 'Boss Kuppa' or 'Kuppa', not 'Boss Creeper'.
Yoshi — The GBA version of Super Mario World 2: Yoshi's Island did not add four-player support via link cable; it only supports two-player in certain minigames.
Mario — The entry states that the Koopalings are Bowser's children, but in established canon they are not his biological children; they are his minions, and Bowser's only biological child is Bowser Jr.
Mario — The entry says the player controls Mario to save Princess Peach and Dinosaur Land from Bowser and his seven Koopalings, but the game's story involves saving Princess Peach and the dinosaur friends of Yoshi, not 'Dinosaur Land' itself as a captive entity.
Waluigi — The claim that Waluigi has maintained a release streak every year from 2000 until 2023 is factually incorrect; he did not appear in any new game releases in 2001, 2004, 2005, 2007, 2009, 2011, 2014, 2016, 2018, 2020, or 2023, among other gaps.
Waluigi — The claim that Waluigi performed a celebratory 'crotch chop' taunt in Super Mario Strikers is inaccurate; the taunt in that game is a leg-sweep kick, not a crotch chop. The crotch chop taunt appears in Mario Strikers Charged, not the original Super Mario Strik
Wario — Wario first appeared in 1992, not 1993 as the entry implies.
Wario — The claim that Wario 'wielded magic to turn populations into minions or grow large' is inaccurate because he does not grow large via magic in Super Mario Land 2, and in Wario's Woods his size-changing is a gameplay mechanic, not a consistent magical trait.
Toad Brigade — The entry lists 'Supporting in Super Mario Bros. W' under Playable Status, but no canon game titled 'Super Mario Bros. W' exists; this is likely a typo or invented title.
Toad Brigade — The 'DID YOU KNOW' section states Captain Toad appears in all but three of Super Mario Odyssey's Kingdoms, but he actually appears in all but four kingdoms (Cap, Cascade, Luncheon, and Bowser's).
Star Spirits — The second Star Spirit is not hidden in a secret fortress in Dry, Dry Desert ruled by Tutankoopa; it is found in Dry, Dry Ruins, and the location is not a 'secret fortress'—it is the ruins themselves.
Star Spirits — The third spirit is guarded by Tubba Blubba, but Tubba Blubba does not eat Boos until his heart is revealed; he eats Boos in general, and his heart is revealed as his weak point after he is defeated once.
Yoshi's Island Residents — The entry states that Baby Bowser casts a spell to transform the entire region into a pop-up storybook, but in the game it is Kamek who casts the spell.
Yoshi's Island Residents — The entry claims that if a Yoshi is knocked out, Kamek's minions kidnap them, removing that character from the game entirely, but in the actual game the baby Mario is captured and the Yoshi is not permanently removed.
