Born into wealth, Charles is the son of Brian and Sharon Xavier. His father was a nuclear researcher. His powers showed forth when he read the mind of a man that could have saved his father from a devastating accident and the man ended up marrying his mother.
At the age of sixteen he went to college earning a Bachelor's degree is biology and went on to get a degree is biophysics and genetics. In graduate school he met and fells in love with a woman but was drafted into the Korean War where he gt a letter that she has moved on with another man.
In Isral he met Erik Lehnsherr who became his best friend and later in life his enemy as Magneto. They learned they have different ideas concerning human and mutant relationships.
During a battle his spine is badly injured leaving him paralyzed and wheelchair bound. Despite this he earned several more degrees and returned to the United States where he started his school to help mutants to harness and master their skills. It is here he also formed the X-Men and uses a device called Cerebro which amplifies his powers and seeks out mutants in need.
Cerebro: Although not a power in itself, Cerebro is listed first for its ability to vastly amplify many of the abilities listed hereafter. This effect is so dramatic that only someone as powerful as him can safely use the machine. While utilizing Cerebro, Xavier can establish telepathic links with all living beings on the planet. It allows him to differentiate between humans and mutants, and to generally grant his mental senses pinpoint accuracy. However, Cerebro is also a terribly dangerous tool. While linked to a being or beings, he can harm or even kill them by focusing intensely enough upon their psyche.
Astral Projection: Charles is capable of projecting his mind into the astral plane, a mutable environment visited by other telepaths and native beings. While in that realm, his is an undisputed king among minds. Charles is unbound by his physical limitations on the astral plane, and is capable of changing both his mental persona and surroundings to suit what's most effective. This makes him an opponent few telepaths would wish to face in astral combat. Another benefit of astral projection Charles' ability to project an image of himself up to fifty miles from his mentally uninhabited body.
Telepathy: Charles Xavier is very likely the most powerful telepath on Earth. He is able to passively pick up surface thoughts with ease. He's also able to actively scan for memories and thoughts, but typically chooses to respect the privacy of others. Telepathic speech is entirely functional. Generally speaking, telepathic shielding is by no means a hindrance to his skills. There is usually a two hundred and fifty mile radius range to his telepathic powers.
Empathy: Charles can feel the emotions of the people around him. This is likely the simplest of his abilities, but not always the easiest to translate. The feelings of others don't necessarily convey the cause of those feelings, and they can also become confused with Charles' emotions, prompting him to withdraw and contemplate upon what he's sensed. If necessary, Charles can prompt others to feel specific emotions, yet his usual respect for other minds makes this a rarely used aspect of the power.
Clairaudience/Clairvoyance : Charles' mind extends his senses, permitting him to overhear speech up to ten miles. He can also use his clairvoyant aspect to gather additional information about a specific location, such as recent events which have taken place there or information about who's touched specific objects.
Aural Sight: Charles is able to perceive and read the emotional auras of those around him. Through this power, he can perceive at a glance whether they are troubled or otherwise in any manner of psychic distress. The additional understanding this grants is one aspect of what makes him such a good listener.
Telepathic Reading: Charles of capable of entering the minds of others as he might the astral plane, exploring their memories in a kind of phyiscal form. Comatose or unconscious individuals are easiest to make contact with in this fashion, and Charles has done so in order to gain a better understanding of the causes behind their problem.
Telepathic Learning: Spending time around someone allows Charles to gradually absorb an understanding of their knowledge on subjects being discussed. The duration of retention is roughly equivalent to the duration of exposure, and is not a replacement for the hard work of learning. Charles is able to extend this accumulated knowledge to others, which is of great benefit to his students, so often considered to be geniuses.
Telepathic Illusions: Charles is capable of projecting illusions to multiple minds. These illusions affect the full range of human senses, and can be virtually anything. A sound, a wall concealing a door, a person, most anything he can imagine. However, it's a taxing process.
Memory Alteration: Xavier can manipulate the memory of others in a variety of ways. The simplest example is erasing a traumatic memory. However, with effort, he can go far beyond that. Charles can erect mental barriers to entrap a subject's existing psyche and then build a new, artificial one around it, effectively creating an entirely different person. It's possible that these barriers can weaken or be destroyed, potentially shattering the false persona as the old one emerges. However, it would take a powerfully telepathic force to bring down the aforementioned confinement.
Psionic Paralysis: Charles can cause instantaneous physical and mental paralysis, targeting anything from one person to large crowds. He's been seen to exercise this ability on areas as large as airports and museums. Most of the time, victims of psionic paralysis are completely unaware of the fact that they were affected, barring some change to the environment. Charles uses this ability in a protective fashion, particularly to cut off engagements before they become deadly.
Psionic Bolts: This discipline allows Charles to lash out at the mind of another being with a 'bolt' of mental energy. In effect, it overloads the opposing psyche with information, rendering them unconscious. Charles will utilize this ability without hesitation in combat situations, particularly while protecting his students, as it is non-lethal.
Psionic Shields: Needless to say, Charles Xavier's mind is protected by a psychic fortress of shielding the likes of which few other telepaths could hope to scratch. He is generally immune to mind control, psionic illusions, and telepathic attacks. Xavier can also cut himself off from telepathic contact if he so chooses, isolating his psyche.
Mental Possession: Charles can control the minds of others, and by extension, their bodies. This is particularly easy to do with targets who have no telepathic shielding. An example would be Xavier's taking over Sabretooth to grab Magneto's neck, threatening to snap it by way of the puppeted brute. In dire circumstances, Charles uses this power to whatever extent is required, but he otherwise refrains from applying it due to the view that it's an extreme violation of the victim.
Telepthic Camouflage: Charles is capable of using his telepathy to erect various types of camouflage. The simplest application is to just conceal his presence entirely by clouding the minds of others, making himself effectively invisible. However, he can also appear as someone other than who is truly is via the same sort of mental manipulation. This has a variety of obvious applications, but will not fool technological countermeasures such as surveillance cameras.
Transference: Charles' ace in the hole, a power he discusses theoretically with his students but has never had to actually use. It allows him to transfer his consciousness and powers into another body, even if his original body should be destroyed. The most ideal recepticle is a braindead individual. Charles retains plans to inhabit the body of his twin brother in the event of such an emergency, and keeps him under the care of Moira MacTaggart for that purpose.
Academics: Charles Xavier holds degrees in biology, biophysics, and genetics. He is also learned historian and philosopher who respects the value of an educated mind. The professor encourages his students to think during his lessons, which he still actively teaches even as headmaster of his namesake school.
Empathy: Charles is a deeply empathetic person, sometimes to his detriment. He is able to pick out the feelings of others without even using his powers in many cases. However, this also lends him a tendency toward forgiveness which is sometimes not deserved. He wants to see the better parts of people, humans and mutants both, and is idealistic about a future in which they can openly exist together.
Piloting: Xavier is a skilled pilot and can readily handle the jet utilized by the X-Men, although he's typically not the one in the driver's seat.
Politics: Charles is not a politician, but he's had the unfortunate responsibility of advocating for mutants politiclally throughout his life. He's acquiainted with many government officials, including the President, some of whom are aware that he's a mutant.
Psionic Training: Xavier's psionic training is extensive. He's learned to meditate, to center himself, and to isolate his mind so as to resist the effects of torture. Mental barriers aside, Charles' fortitude of will was such that he had to be controlled directly by Jason, William Stryker's son, rather than merely being given a dose of the man's spinal fluid.
Psychology: Simply put, Xavier knows what makes people tick. He doesn't have a degree in psychology, but a lifetime spent as the world's most advanced mind has given him countless opportunities for insight into the human psyche. Charles can read people like a book, much to the displeasure of less obedient students.
Technology: Professor Xavier has a brilliant technological mind. The Institute is populated with a wide array of cutting edge devices he's dreamed up, mostly for use by the X-Men. Possibly the most important creation is the telepathic amplifier Cerebro, which he developed alongside his best friend, Erik Lensherr.
WEALTH: Charles is a billionaire to put it lightly. He is worth over 3 billion dollars, and at any given time he can liquidate his finances not tied into companies to give him three million dollars spending money. If he needs more, he would have to sell some things share wise
XAVIER MANOR: The Xavier family home has been slowly transformed into the school. There is enough rooms to house countless classrooms, dorms, a kitchen for cooking, a dinning room to hold all the students and faculty at once. It has an expansive estate for privacy for the school.
ROLLS ROYCE & WHEEL CHAIR: He is carried around in a Rolls Royce and has a specialized wheelchair to get around in as well.
DANGER ROOM: The bread and butter of holographic technology. Its the cutting edge in training also. Providing a vast array of scenarios' for the x men to train in.
CEREBRO: This is Charles' pet project, It amplifies his telepathic power so that he can reach a mutant any place in the world. It has been known to go into the cosmos to, but hate power needed for that is extensive. often using it to find troubled mutants in need of his help, Charles has had a lot of practice with it.
STUDENTS: Viewing them as his greatest asset they are what keeps Charles going. They are what make him wake up in the morning, and what causes him to fall asleep exhausted every night. They are each his children and all hold a special place in his heart. He tries to not play favorites with them, but some are a little more liked then others, but none are treated better then the other.
MILITARY CONTACTS: From his stint in the military Charles made quite a few friends. Using them when he needs new information or help with projects, Or even giving his students jobs when they graduate.
Charles Xavier is one of the most intelligent men someone can meet. One of his main goals is to bring forth the peaceful co existence of humans and mutants. He wants to protect mutants from humans that want to harm them as well as protect humans from mutants that wish them harm as well. He wants to help mutants to learn to use and control their powers through his school. Charles acts as an public advocate for mutant rights. Like anyone he too has his darkside he keeps well hidden.
Paraplegic: Professor X is unable to walk due to spinal damage and is bound to an electric wheelchair.
Dark Side: Xavier was shown to have a dark side, a part of himself that he struggles to suppress. Xavier was shown to be secretive and manipulative. He has secret files the Xavier's files, aka the "Xavier Protocols," which detail how to kill many of the others should the need ever arise, such as if they went rogue.
