Professor Charles Francis Xavier, also known as Professor X, is a fictional character, a Marvel Comics superhero known as the leader and founder of the X-Men.
Throughout most of his comic book history, Xavier is paraplegic, although his body houses one of the world's most powerful mutant minds. As a high-level telepath, Xavier can read, control and influence human minds. A scientific genius, he is also a leading authority on genetics, mutation, and psionic powers.
Professor X is a mutant who possesses vast telepathic powers, and is among the most powerful telepaths in the Marvel Universe.
Professor X is able to perceive the thoughts of others or project his own thoughts within a radius of approximately 250 miles (400 km). With extreme effort, he can greatly extend the range of his telepathy. He can learn foreign languages by reading the language centers of the brain of someone adept, and alternately "teach" languages to others in the same manner; Xavier once trained a new group of mutants mentally, subjectively making them experience months of training together, while only hours passed in the real world.
he can cause the loss of specific memories or even total amnesia. He can also project powerful mental 'bolts,' enabling him to stun the mind of another person into unconsciousness or even cause death. These 'bolts' inflict damage only upon other minds, having a negligible effect on non-mental beings, if any. The manner in which Xavier's powers function indicates that his telepathy is physical in some way, as it can be enhanced by physical means and can be disrupted by physical means
Xavier can perceive the distinct mental presence/brain waves of other superhuman mutants within a small radius of himself. To detect mutants to a wider area beyond this radius, he must amplify his powers through Cerebro and subsequently Cerebra, computer devices of his own design which are sensitive to the psychic/physical energies produced by the mind.
