Telepathy

Professor X — Requires Cerebro to extend his telepathy to global range; unaided he is constrained to a far smaller radius

Emma Frost — Her diamond form grants near-invulnerability and removes her telepathy entirely while active

Martian Manhunter — Maintains a simultaneous telepathic link across the entire Justice League as standard operating procedure

Jean Grey — Fights on the astral plane, where the physical body is irrelevant and defeat can be permanent

Saiki Kusuo — Involuntary constant telepathy forces him to wear a limiter in order to function at all

Madame Web — Blind and paralysed, she operates primarily through psychic contact rather than physical presence

Jean Grey — Reads and projects thought across planetary distance

Jean Grey — Shields an entire team's minds from detection simultaneously

Professor X — Locates any mind on Earth when amplified by Cerebro

Professor X — Edits and restores memory, an ability the stories treat as a moral problem

Professor X — Projects an astral form able to act away from his body

Saiki Kusuo — Cannot switch the ability off, which is the premise of the comedy rather than a power-up

Saiki Kusuo — His limiters are physical objects, so the power is throttled by hardware rather than by will

Raven — Reads and projects emotion rather than thought, which is the stated distinction

Raven — Absorbs another person's injuries into herself to heal them

Raven — Her restraint is stated to be emotional control, not power level — Trigon's influence is the risk

Loki — Communicates and manipulates at distance without being present

Loki — Reads intent well enough that deception is his primary weapon rather than force

Psylocke — Reads and shields minds at the level of the X-Men's front-line telepaths

Psylocke — Projects illusions into a target's perception directly

Psylocke — Her powers swapping with Betsy Braddock's is a continuity event, not a power description

Madame Web — Contacts Spider-Man mentally across distance without meeting him

Franklin Richards — Reads and projects thought from early childhood

Franklin Richards — His power is repeatedly suppressed by his parents, which is the stated reason he is not a constant plot solution

Peter Petrelli — Reads minds using an ability taken from another character

Peter Petrelli — Later restricted to one ability at a time, a deliberate rewrite of the power

Eleven — Locates specific people at any distance by entering a sensory void

Eleven — Needs an audio anchor and sensory deprivation to reach a target

Gorilla Grodd — Reads and projects thought across a city

Gorilla Grodd — From Gorilla City, a hidden technologically advanced civilisation

Gorilla Grodd — Force-feeding is a recurring and deliberately grotesque method of his

Falcon — A telepathic link with birds, originally his only actual power

Falcon — The link was created by the Red Skull with the Cosmic Cube, not by accident

Falcon — Directs birds to search an area faster than any team could
