Professor X

Charles Francis Xavier, also known as Professor X, is one of the major characters from the Marvel comics.

Professor Charles Xavier is the creator of the X-Men and founder of the Xavier School for Gifted Youngsters. His dream of peaceful coexistence between mutants and humanity has long been the driving force for the X-Men. An immensely powerful telepath and scientific genius, Xavier was among the world's greatest masterminds. Killed at the hands of a Phoenix crazed Cyclops, Xavier's memory and dream still remains and motivates his X-Men to keep fighting for a world that fears and hates them.

Personality
Xavier has built a lifetime reputation on being caring and compassionate to his fellow mutants. Even as a child, he helped a young Mystique find her place in the world. He refuses to give up on people, always believing they can be saved, as seen in Mystique, Jean Grey and even his "arch rival" Magneto. His greatest attribute is his ability to believe in hope and to never give up no matter the odds.

Throughout his adult life Xavier has taught and trained mutants, to not only deal with their abilities but more importantly how to live in and cope in a world that fears them. He became a mentor and father figure to many mutants, giving them a home when many were lost. Even Lehnsherr, his long-time rival, holds Xavier in very high regard, knowing everything he's done for mutant.

However, Xavier was not always so hopeful and heroic. During the late 1960s and early 1970s, the loss of Raven, his legs, his students and his friend Erik was too much for him, and he hid away from the world in the mansion. Xavier had lost hope and became addicted to Hank McCoy's serum that returned him his legs, refusing to let his powers return and overwhelm him. It took the combined efforts of Wolverine and the future Xavier to return him to his usual heroic personality by showing him all the good he will do, and all the suffering that could be prevented.

There are also moments when Xavier reveals a more manipulative aspect of himself, such as when he placed psychic blocks on Jean Grey's powers out of fear that she would be uncontrollable, or when he defies his own code of only using his powers on a willing subject, such as Mystique or Magneto. When controlling certain aspects of those around him he firmly believes that it is for their own good, refusing to acknowledge or listen to the consequences this can have, a trait which led to Jean destroying his original body and him and Mystique becoming estranged, the latter of which Charles solely blamed Erik for until their reunion in 1973 when he finally admitted what controlling her had done.

Unlike most mutants, Xavier does not hate humans, believing that mutants and humans can find a way to coexist, and he will not risk human lives any more than he would a mutant's. While preferring more diplomatic solutions, Xavier isn't afraid to be forceful, but only if it is the last resort.[3] In the revised timeline, his ability to condone violence to the sake of defending his students and other innocents is greatly increased after defeating Apocalypse, enough to impress and satisfy Erik, who saw him as naive and foolish for being so trusting of people in the past and not being truly willing to fight.

Xavier has deep and complex relationships with many of the main X-Men characters. Both he and Erik Lehnsherr have a very complicated history, fighting each other over several decades, and yet there is still an almost brotherly connection between them. The two have spent many hours playing chess together and debating mutant affairs. Xavier and Raven Darkholme also have a complicated relationship, with Raven being almost like a sister for Xavier, despite her troubled past. Hank McCoy is Charles' greatest ally, as he refused to give up on him, even when Charles had given up on himself. Logan's angry and self-centered attitude contrasts with Charles, but the two worked together to unlock the secrets of the former's mind, and eventually, Logan grew to see Xavier as a mentor-like figure and became one of his most loyal X-Men.

By 2029, Xavier had mostly lost his good nature. Having been hidden by Logan for numerous years in isolation, Charles spent his days randomly mumbling unless given his medication. When he had clarity, Charles was bitter, often swore and crazy. However, the last spark of his compassion was directed at Laura, who was Logan's genetic daughter; Xavier spent his last hours trying to help her escape from the Reavers and serving as a grandfather figure to Laura before enjoying time with the Munson family during his stay at their house. He also urged Logan to aid the Munsons' when their horses ran amuck and consciously used his powers for a final time to calm the horses, showing that his great mind was not completely gone yet.

Abilities
Professor X is one of the most powerful telepathic mutants in the world. He is an Omega Class Telepath, equaling Emma Frost's abilities. He is able to read minds and communicate telepathically on a high level nearly anywhere around the world or even on a galactic level. With his telepathic power Professor X can manipulate, erase and create memories, control the actions of people and can mentally harm someone even to the degree of causing death. His gift allows him to opens channels of communication and plant suggestive thoughts even if a person is extremely far away. He is considered a very intelligent man, being able to learn things quickly by accessing someone's brain and learning from it. He can also give his teachings to other people by telepathy, and they can learn as quickly as him as well. This includes learning alien languages too. Xavier can also make it seem like he can alter time to a degree when Xavier trains a new group of mutants telepathically which seems as if they've only been learning for months when in reality it was in hours. In truth, this ability was just him using his telepathy to alter their perceptions of time. He also has the ability to project his astral form and control the astral plane.

Trivia

 * Xavier's favorite book is known from the X-Tinction Agenda storyline to be T.H. White's The Once and Future King. Magneto (who apparently shares Xavier's passion for the novel) can be seen reading it at the beginning of X2 while in prison, and also paraphrased White's famous lines about territory and war, saying, "When will these people learn to fly?" Also, at the close of the film, Xavier asked his students if they were familiar with the work.
 * Xavier was a billionaire with a net worth of 3.5 billion dollars, according to Fantomex.
 * Xavier enjoyed Japanese green tea, according to Storm.
 * Xavier seemingly disliked being called "Charlie" by Wolverine.
 * Before the X-Men's first encounter with the Brotherhood of Evil Mutants, Professor X received a premonition about Magneto's plans. But precognition is not usually among his powers.
