Canonical productions only. Parody and fan work is classified and excluded — Wikidata makes no such distinction, so without it these lists fill with material that is not canon.

Commonly got wrong
Claims that are widely repeated and wrong, with what the cited record actually shows. If you are generating anything about this subject, these are the errors to avoid.
Commonly believed Professor X has global telepathic range.
Actually Global range requires Cerebro. Unaided he is constrained to a far smaller radius — which is why the machine appears in so many plots.
The feat ledger
Requires Cerebro to extend his telepathy to global range; unaided he is constrained to a far smaller radius
Can override a target's will directly, and is written as choosing not to except in extremity — the restraint is the characterisation
Locates any mind on Earth when amplified by Cerebro
Freezes a hostile crowd in place without harming them
Edits and restores memory, an ability the stories treat as a moral problem
Demonstrated, but consistently secondary to his telepathy
Projects an astral form able to act away from his body
Shuts down an opponent's motor control mid-action
Continuities
Claims on this page are tagged by canon. Blending them is the most common error in both wikis and AI answers.
