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.

Charles Xavier — The paralysis origin described as 'caused by a collapsing wall during an alien attack (the Lucifer incident) in X-Men #5 (1964)' is incorrect; Lucifer caused a stone block to fall on Xavier's legs, not a collapsing wall.
Logan — The entry states Logan 'originated as the main protagonist and central figure of 20th Century Fox's X-Men film series.' This is inaccurate; the character originated in Marvel Comics, not as a film protagonist.

Charles Xavier — The entry states that Xavier's paralysis was originally caused by a falling stone block from the alien Lucifer, but the phrasing 'originally caused by... though the most widely known origin... is a sniper shot' is misleading because the Lucifer origin is the o
Healing Factor — In X-Factor #10, the Marauders severely injured Angel's wings, which were later amputated in X-Factor #16, not #15.
Healing Factor — Apocalypse transformed Angel into Death, giving him metal wings and a blue costume, not blue skin.
Adamantium Skeleton — The entry incorrectly implies that 'proto-adamantium' is a distinct substance from true adamantium, whereas in Marvel canon the shield's alloy is an accidental precursor to adamantium, not a separate unrelated material.
Inferno — The claim that Inferno was one of the first major crossovers to integrate street-level heroes like Daredevil into an X-Men saga is inaccurate because Daredevil had already crossed over with the X-Men in 'The Mutant Massacre' (1986) and 'Fall of the Mutants' (1
Inferno — The 'Did You Know' section states that Inferno did not involve Nightcrawler's disappearance or return from Limbo, and that occurred in 'Fall of the Mutants,' but this is factually incorrect: Nightcrawler's disappearance into Limbo and his return occurred durin
