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.

Simon — Simon defeats Lordgenome by using Lagann (not Gurren Lagann) to pierce Lazengann's cockpit after Gurren Lagann is destroyed, and the final blow is delivered by Lagann's drill.
Nia Teppelin — Nia first appears in Episode 15, not Episode 16.
Nia Teppelin — Nia and Simon become engaged in Episode 22, not Episode 16.
Anti-Spiral — The Moon seen in the first half of the series was not the real Moon; it was Lordgenome's flagship (the 'fake Moon') all along. The real Moon was never present in the first half; it was hidden in a pocket dimension by the Anti-Spiral and later retrieved by Team
Anti-Spiral — The claim that 'the real Moon was not hidden in a pocket dimension—it was destroyed or otherwise accounted for' is incorrect. In the series, the real Moon is explicitly revealed to have been hidden in a pocket dimension by the Anti-Spiral, and it is later brou
Kamina's Squad — The entry misquotes Kamina's dying words; the correct line is: 'Believe in yourself. Not in the me who believes in you. Not in the you who believes in me. Believe in the you who believes in yourself.'
Kamina's Squad — The entry states the rebuilt city is explicitly called 'Kamina City' in the TV series epilogue, but the city is never named that in the anime.
Anti-Spirals — The entry states 'Their defeat was achieved through the Super Tengen Toppa Gurren Lagann mecha in the final battle,' which oversimplifies canon; the decisive blow was delivered by Simon and the core Gurren Lagann, not solely the Super Tengen Toppa form.
Spiral Commanders — The entry says Yoko permanently takes the name Yomako after the timeskip, but she only uses it as a pseudonym while teaching on Kiyal Island.
Spiral Commanders — The entry says Simon gives Lagann's key to Gimmy alone, but he gives it to both Gimmy and Darry.
Underground Dwellers — The intro states Lordgenome made a pact with the Anti-Spiral after his defeat, but in canon he made the pact before or as part of his surrender, not after a defeat.
Underground Dwellers — The 'DID YOU KNOW' section repeats the error about Lordgenome making a pact with the Anti-Spiral after his defeat.
Kamina Legend — Kamina's catchphrase is 'Just who the hell do you think I am?!' (singular) and 'Just who the hell do you think we are?!' (plural), not the combined form 'I/we am/are' as written.
Kamina Legend — Kamina does not wield a nodachi; he wields a normal-sized sword (often called a katana or longsword) that he took from the village chief, not a nodachi.
