Charles Francis Xavier is a mutant who possessed strong telepathy and arguably the most powerful mind on Earth. His abilities allowed him to read the thoughts of others, impose his own will to take over other people's minds or erase their memories and appear as an image in the mind of others. Xavier dedicated his life to fighting for peaceful co-existence between man and mutantkind. To aid in this crusade, he founded a school for gifted youngsters to secretly train young mutants to control their amazing powers. Xavier now uses his special abilities to lead his clandestine team of X-Men into battle against Eric Lehnsherr and his brotherhood of evil mutants.
Powers and abilities
Professor X has a wide variety of telepathic powers.
Telepathic Cloak: He can make himself invisible by manipulating the minds of others. He used this to hide himself, Magneto, and all the assault troops while en route to the dacha of a Russian general without being detected while in the back of the caravan.
Telepathic Communication: He is able to telepathically communicate with others.
Mental Detection: He is able to sense the whereabouts of nearby mutants. He demonstrated this when he sensed that Rogue had left the mansion and was at the train station. This ability is enhanced when he uses Cerebro.
Mind Control: He is able to manipulate the minds of others to get them to do what he wants them to do. He does not like using this ability to make people do what he wants them to do all the time as he said when talking to Magneto while going to Jean Grey's house when she was a child.
Mental Possession: He is able to enter the mind of another to control their body and see from their perspective. He demonstrated this at the dacha of a Russian general and possessed the mind of a guard for a short period of time.
Mental Sedation: He can make others fall asleep just by telling them to.
Mind Transferal: When his physical body was destroyed in X-Men: The Last Stand, he transferred his consciousness into a host body, namely that of his brain-dead twin brother.
Paralyzation: He can mentally paralyze others, making it appear as if time has been stopped.
Mental Link: He has the ability to develop a mental link with any person which remains as a connection to that individual. This was shown when Jean Grey linked with him to communicate with the others in the X-Jet before perishing.
Mental Amnesia: He has the ability to cause loss of particular memories and amnesia in another person or group of people. This was demonstrated at the end of X-Men: First Class with Moira MacTaggert.
Abilities
Genius-level Intellect: A natural genius, Xavier is a leading authority on genetics, mutation, and psionics. He also possesses considerable expertise in other life sciences. He is highly talented in devising equipment for utilizing and enhancing psionic powers. Xavier is also quite the masterful tactician and strategist, effectively evaluating situations and devising swift responses.
Weaknesses
Paraplegic - Xavier has been unable to walk due to spinal damage from the waist down, suffered when one of the bullets Magneto bounced off using his magnetic powers hit his lower spine in 1962.
Xavier is unable to use his telepathic abilities on other mutants who form some kind of shield to block psychic attacks, such as Emma Frost's diamond shield or the mysterious helmet worn by Sebastian Shaw, that was later acquired by Magneto.
In X-2, William Stryker developed a "neural inhibitor" headset that prevented Xavier from using his telepathy; thereby making him vulnerable to the illusions of his son Jason.
