Strength Level: Professor X possesses the normal human strength of a man of his age, height, and build who enages in regular exercise.

Superhuman Powers: Professor X is a mutant who possesses vast psionic powers, making him arguably the world's most powerful telepath. He can read minds and project his own thoughts into the minds of others within a radius of approximately 250 miles. With extreme effort, he can greatly extend that radius. Professor X can also psionically manipulate the minds of others, for example to make himself seem invisable and to project illusions. He can also induce temporary mental and/or physical paralysis, loss of partiular memories or even total amnesia. Within close range, Professor X can manipulate almost any number of minds for such simple feats. However, he can only take full possession of another being's mind one at a time, and he can only do so if he is within that being's physical presence.

Furthermore, Professor X can project powerful mental bolts of psionic energy enabling him to stun the mind of another being into unconsciousness. These bolts only apply force upon other minds; they do not inflict physical damage. Professor X can also sense the presence of other superhuman mutants within a small radius of himself by perceiving the distinct mental radiations emited by such beings. In order to detect the presence of mutants beyond this radius, he must amplify his powers. He often does this by using first Cerebro and more recently Cerebra, devices that are sensitive to that portion of the electromagnetic spectrum that contains mental frequencies.

Professor X can project his astral form, the sheath of his life essence, onto absract dimensions congruent to our own known as astral planes. There, he can use his powers tp create ectoplasmic objects. He cannot engage in long-range astral projection on the earthly plane.

Special Skils: Professor X is a leading authority on genetics, mutation, and psionic powers, and has considerable expertise in other life sciences. He is also highly talented in devising equipment for utilizing and enhancing psionic powers.

Special Limitations: Part of Professor X's spine is shattered, thus confining him to a wheelchair.

History: Charles Francis Xavier was born the son of nuclear researcher Brian Xavier and his wife, Sharon. Following her husband's accidental death, Sharon married Brian's colleague, Kurt Marko. Cain, Kurt's son from a previous marriage, came to live at the Xavier's Westchester mansion shorly thereafter. A cruel and spiteful boy, he bullied his new stepbrother, and his father secretly beat him as punishment. Charles felt is sibling's pain first-hand thanks to the emergence of his mutant telepathic powers. Following their mother's death, a fire in the family home took Kurt's life, leaving the stepbrother's alone.

By the time he graduated high school, Charles was completely bald as a side effect of his Mutant nature. He entered Bard College in New York at age 16 and earned his bachelor's degree in biology within two years. He was then excepted into the graduate-studies program at England's prestigious Oxford University, where he earned degrees in genetics and biophysics. There, Charles met and fell in love with a young Scottswoman named Moira Kinross. Their passionate discussions on the subject of genetc mutation gave way to an equally passionate romance, and they planned to marry. Their only obstacle was Moira's former boyfriend, Joe MacTaggert, a lance corporal in the Royale Marines and a bully, just like Cain. In Joe's eyes, Charles was a godd-for-nothing intellectual, so Charles enlisted in the military after completing his studies at Oxford to validate himself in terms his rival would understand.

Charles quickly became something of a legend in the area of search and rescue thanks to his mutant abilities. Attached to the same unit as his stepbrother, Charles was present when Cain deserted under fire during a mission in Asia. Following him in the hope of convinicing him to return to their unit, Charles witnessed Cain's discovery of the mystical Ruby of Cyttorak and his transformation into the superhuman Juggernaught. Charles escaped the subsequent cave-in, mistakenly believing his stepbrother was dead.

Later, Charles was devastated when Moira broke off their engagement without explanation. He left the Army and began traveling the world. In Caro, Egypt, he encountered Amahl Farouk, a mutant capable of summoning forth the darkness in the souls of others. This confrontation led to Charles' decission to devote his life to protecting humanity from evil mutants and saving innocent mutants from human oppression.

Charles next traveled to Israel, where he fell in love with Israeli diplomat Gabrielle Haller. He also befriended a fellow drifter named Erik Magnus Lehnsherr, the mutant who would become his greatest enemy: Magneto, self-styled master of magnetism. While Charles optimistically believed that humans an mutants could coexist, the Jewish Magnus foresaw mutants as the new minority to be persecuted and hunted because of their differences. Together, the pair prevented the nefarious Baron Von Strucker from launching his terrorist group Hydra on an unsuspecting world. Magnus departed with Strucker's gold, and upon departing Israel himself, Charles was unaware that Haller was pregnant with his son David.

En route to the United States, Charles encountered the alien Lucifer in the Himalayas. To prevent any interference in his race's planned invassion of Earth, Lucifer dropped a massive stone block on Charles, crippling his legs. In desperation, Charles called out with his mental powers and touched the mind of a young mutant named Tessa who was opperatng as a mercenary in the neighboring Hindu Kush mountains. Tessa came to his aid and Charles was airlifted to safety. During his convalecence in an Indian hospital, Charles met Amelia Voght, a young nurse who fell in love with him and renewed his will to live.

Charles resumed graduate work at Columbia University in New York; after receiving a PhD in anthropology, he spent several years in London earning a PhD in psychiatry. There, Charles renewed his friendship with Moira, who had married Joe MacTaggert and was now a renowned geneticist, and the two began discussing the idea of founding a school for mutants.

Charles returned to America and resumed his studies of mutation. It was notlong before Professor John Grey, a friend of Charles' from Bard College, brought his young daughter Jean to Charles for help. Jean had been traumatized when she telepathically experienced the death of a friend. Charles aided in her recovery, and in the ensuing years trained her to use her mental powers. Charles later met with Fred Duncan, an F.B.I. agent investigating the growing number of mutants. Charles told Duncan of his plan to locate young mutants and enroll them in a school using his ancestrial mansion home as a base to train them to use their powers for humanity's benefit. Amelia remained with Charles until the young mutant Scott Summers came to study at the school. She left fearing an escalating genetic arms race between Charles and Magnus. Over the following months, Charles used his mutant-locating computer Cerebro to assemble his original group of students: Cyclops, Ice Man, Angel, Beast, and Jean Grey, who took the name Marvel Girl. He dubed his students the "X-Men", because each possessed an "extra" ability that normal humans lacked. Charles also recruited Tessa at this time, but kept her presence at the mansion a secret from his other students as he planned to use her talents as a spy.

Soon after, Charles learned of a planned invasion of Earth by the alien Z'nox and theorized that he would have to link the minds of the majority of morally upright people on Earth to stop the invaders. However, he needed time in virtual isolation to prepare his mind for such an awesome task. To that end, Charles had the mutant shape-changer named Changeling impersonate him so that his students, except for Jean to whom he entrusted his plan, would remain none the wiser. After Changeling died on a mission with the team, Charles allowed the X-Men to believe he was dead. Months later, Charles revealed his deception to his students and repelled the invaders.

Years later, when his original students were captured by the sentient island-being named Krakoa, Charles recruited Banshee, Colossus, Nightcrawler, Storm, Sunfire, and Wolverine as a new team to rescue them. Afterwards, Cyclops was the only original member to remain and help Charles train the new recruits. Before long, Charles began to experience psychic nightmares from an alien world. These images were sent by Lilandra, princess of the intergalatic Shi'ar Empire, who was seeking assistance to defeat her mad brother D'Ken. In the course of the ensuing struggle, Charles and Lilandra fell in love, and for a time he lived on Chandilar, the Shi'ar throneworld, as her consort.

Charles and Lilandra spent much time together on Earth before her coronation, and during this time the X-Men fought Magneto in Antartica. After the battle, most of the team made it to the hidden jungle in the icy wasteland known as the Savage Land. Phoenix and Beast returned to Westchester, believing the rest of the team had died. Heartbroken, Charles accompanied Lilandra to the Shi'ar homeworld for her coronation. When he eventually learned that the rest of the X-Men were actually alive, he returned to Earth.

Sometime later, Lilandra faced a coup by her sister Deathbird and the alien Brood race. The X-Men and the space pirates known as the Starjammers helped defeat them, but Charles had been implanted with a Brood egg which would ultimately hatch and transform him into the Brood's new queen. When Charles tried to probe the implant, he was sent into a coma; after he awoke, he learned the X-Men had been captured by the Brood and taken into space. Fearing his students dead, and under subconscious commands from the larval Brood within them, Charles gathered a new group of young superhuman students he named the New Mutants. Following the X-Men's return, the queen hatched and transformed Charles into a Brood. Although his body was destroyed, with the X-Men's help, Charles was able to retain mental control of the Brood Queen long enough for the Starjammers' physician Sikorsky to clone him a new body with no disabilities. It was sometime before Charles could walk again due to his psychosomatic pain of being crippled for so long.

Eventually, Charles began to take his most active role ever with the X-Men by accompanying them on missions. During this time, Gabrielle requested Charles' help in treating her son David, the powerful psionic mutant known as Legion, who suffered from multiple personality disorder. Charles learned that David was his son and helped him emerge from his autistic condition, afer which father and son were reunited.

After a brutal beating at the hands of a group of college students, Charles' cloned body began to deteriorate and he was forced to leave Earth with Lilandra and the Starjammers to heal. He left the school in the seemingly reformed Magneto's care, joining Lilandra in the fight to regain her rightful place on the Shi'ar throne. After an extended sojourn in space, Charles finally returned to Earth, and both the original and second teams of X-Men reassembled under his leadership to battle his old enemy Farouk, now calling himself the Shadow King. Charles' spine was broken in the ensuing battle, leaving him crippled and confined to a wheelchair once more.

Since the X-Men were all now highly trained adults, Charles renamed his School as the Xavier Institute for Higher Learning. He also assumed control of a private institution, the Massachusetts Academy, and transformed it into a new School for Gifted Youngsters. There yet another new crop of young mutants, Generation X, learned to use their budding superhuman abilities.

Charles' next major confrontation came when Magneto initiated a lethal electromagnetic pulse inside Earth's atmosphere. Charles and his X-Men took the fight to Magneto's orbit base; in the ensuing battle, Magneto viciously attacked Wolverine, forcibly extracting from his body the metal that had been bonded to his skeleton. Seeing no other alternative, Charles used his mental powers to shut down Magneto's conscious mind. During this desperate act, the evil portion of Magneto's psyche implanted itself within Charles' mind. The eviL aspect, combined with the darkest part of Charles' soul, eventually gained sentience as the powerful psionic being known as Onslaught.

After a pitched battle, America's greatest super heroes narrowly defeated Onslaught. To ensue that Charles never again spawned such a being, he was taken into custody by the United States government. Although Charles was willing to pay for the price for his folly, he was appalled when the government turned him over to the custody of Bastion, head of the anti-mutant Operation Zero Tolerance. After the government shut down Zero Tolerance for overstepping it's authority, the X-Men set out to search for their missing founder. When they finally located him, Charles was leading a new incarnation of the Brotherhood of Mutants in an attempt to defeat the now-sentient Cerebro. Charles ultimately defeated Cerebro by showing him the unique importance of each living individual.

Charles suubsequently returned to the X-Men, but soon after disbanded the team over fears a member of the shape-shifting alien race known as the Skrulls had infiltrated them. After Wolverine was seemingly killed in battle, it was revealed that it was actually a Skrull impersonating him that had died, thus proving Charles' theory correct. The X-Men reformed in time to foil the plans of the eternal mutant Apocalypse, who saught to rule the world by using the power of the Twelve - a fabled team of mutants, including Charles and Magneto, who were destined to usher in a new golden age for their kind. After Apocalypse was defeated, Charles departed Earth with a team of adolescent mutant Skrulls, whom he dubbed Cadre K, to help them find a new home among the stars.

Charles later returned to the X-Men to lead them once more, but was captured by Magneto who had been amasing an army on the island nation of Genosha in preperation for an all-out war against humanity. The X-Men rescued their founder, and Magneto was himself crippled by Wolverine. Soon after, giant mutant-hunting robotic Sentinels sent by Charles' malevolent genetic twin ister, Cassandra Nova, obliterated Genosha's population. Charles found himself powerless against his sister after she switched bodies with him, trapping his mind in her own dying form. In Charles' body, Nova publicly outed him as a mutant and then left Earth with Lilandra, who she convinced to order the Shi'ar superhuman Imperial Guard to destroy all mutants on Earth, starting with the X-Men. After a pitched battle during which Nova's deception was revealed, Jean Grey absorbed Charles' consciouness into her own mind, then used the mutant-locating Cerebra device to hide pieces of it in the minds of every mutant on Earth. When Nova went to use Cerebra to kill all of Earth's mutants, she unwittingly reformed Charles' consciouness and he forced her out of his body. Once Nova was defeated, Xorn, the X-Men's newest member healed Charles' body.

Free of having to hide behind a veil of secrecy, Charles took to his now public role as a mutant rights activist with vigor. He opened his school to mutants everywhere, and the X-Men became the new faculty. It was not long, however, before Charles' world came crashing down around him when Xorn was revealed to be Magneto in disguised. His old nemesis had survived the Genoshan holocaust and infiltated the X-Men, gathering together a class of students to use as his new soldiers for the war against mankind. Magneto crippled Charles once more and took control of New York City, rechristening it New Genosha. Using a neuro-toxic drug known as Kick to boost his powers, Magneto planned to reverse the magnetic poles of the Earth, destroying humanity and ushering in a new age for mankind. However, his students rebelled, and the timely arrival of the X-Men saw a permanent end to his plans after Wolverine decapitated him.
