Professor X (Prof. Charles Francis Xavier) is a character appearing in American comic books published by Marvel Comics. Created by writer Stan Lee and artist/co-writer Jack Kirby, the character first appeared in The X-Men #1 (September 1963). The character is depicted as the founder and occasional leader of the X-Men.
Xavier is a member of a subspecies of humans known as mutants, who are born with superhuman abilities. He is an exceptionally powerful telepath, who can read and control the minds of others. To both shelter and train mutants from around the world, he runs a private school in the X-Mansion in Salem Center, located in Westchester County, New York. Xavier also strives to serve the greater good by promoting peaceful coexistence and equality between humans and mutants in a world where zealous anti-mutant bigotry is widespread. However, he later abandons his dream in favor of establishing a mutant nation in Krakoa.
Throughout much of the character's history, Xavier has been depicted with paraplegia and uses a wheelchair. One of the world's most powerful mutant telepaths, Xavier is a scientific genius and a leading authority in genetics. He has devised Cerebro and other equipment to enhance psionic powers and detect and track people with the mutant gene.
Xavier's pacifist and assimilationist ideology and actions have often been contrasted with that of Magneto, a mutant leader (initially characterized as a supervillain and later as a complex antihero) with whom Xavier has a complicated relationship. Fans and commentators often compare Xavier and Magneto to Martin Luther King Jr. and Malcolm X respectively, though the amount of authorial intent supporting this comparison is disputed. Writer Chris Claremont, who developed Xavier's characterization and originated Magneto's backstory, drew from Israeli politics, comparing Xavier to David Ben-Gurion and Magneto to Menachem Begin. Later writers have additionally emphasized secretive, ruthless, and manipulative aspects of Xavier, while the later "Krakoan Age" storyline sees him align with Magneto to establish a sovereign mutant nation.
Professor X has been substantially adapted into media outside comics, including animated series and video games. The character has been portrayed by Patrick Stewart and James McAvoy in 20th Century Fox's X-Men film series (2000–2019), and by Harry Lloyd in the third season of the television series Legion (2019). Stewart reprised the role in the Marvel Cinematic Universe films Doctor Strange in the Multiverse of Madness (2022) and Avengers: Doomsday (2026). Christopher Abbott will portray the primary MCU's incarnation of Professor X in the untitled X-Men film (2028).
Publication history Creation and influences Created by writer Stan Lee and artist/co-writer Jack Kirby, Professor X first appeared in X-Men #1 (September 1963). Stan Lee has stated that the physical inspiration of Professor Xavier was from Academy Award-winning actor Yul Brynner.Stan Lee: Conversations The first issue introduces the original team, with Marvel Girl presented as a new pupil at Xavier's school, apparently the first female student, and meeting Cyclops, Beast, Angel, and Iceman. In X-Men #7, Professor X briefly leaves the X-Men and leaves Cyclops in command. Ben Saunders observes that "the direction of the X-Men will often pivot on the question of Xavier's absence or presence, and the emotional impact of his comings and goings on the team, particularly on Cyclops."
Xavier's goals are to promote the peaceful affirmation of mutant rights, to mediate the co-existence of mutants and humans, to protect mutants from violent humans, and to protect society from antagonistic mutants, including his old friend, Magneto. To achieve these aims, he founded Xavier's School for Gifted Youngsters (later named the Xavier Institute) to teach mutants to explore and control their powers. Xavier's students consider him a visionary and often refer to their mission as "Xavier's dream". He is highly regarded by others in the Marvel Universe, respected by various governments, and trusted by several other superhero teams, including the Avengers and the Fantastic Four.
Later stories Writer Scott Lobdell established Xavier's middle name to be "Francis" in Uncanny X-Men #309 (February 1994).
He often acts as a public advocate for mutant rights and is the authority most of the Marvel superhero community turns to for advice on mutants. In a number of comics, Xavier is shown to have a dark side, a part of himself that he struggles to suppress. In X-Men #106 (August 1977), the new X-Men fight images of the original team, which have been created by what Xavier says is his "evil self ... who would use his powers for personal gain and conquest", which he says he is normally able to keep in check. In the 1984 four-part series titled The X-Men and the Micronauts, Xavier's dark desires manifest themselves as the Entity and threaten to destroy the Micronauts' universe.
In the Onslaught storyline, the crossover event's antagonist is a physical manifestation of Xavier's dark side. Also, Onslaught is created in the most violent act Xavier claims to have done: erasing the mind of Magneto. During the Onslaught storyline, the X-Men find Xavier's files, the "Xavier Protocols", which detail how to kill many of the characters, including Xavier himself, should the need ever arise, such as if they went rogue.
While he always presented himself as an advocate for mutant rights, Professor X's status as a mutant himself and originator of the X-Men only became public during the 2001 story "E Is for Extinction". In Astonishing X-Men vol. 3, #12 (August 2005), it is revealed that Xavier keeps the Danger Room trapped and experiments on it for years despite learning of its sentience, an act that Cyclops calls "the oppression of a new life" and equates to humanity's treatment of mutants. However, X-Men Legacy #220 - 224 reveals that Xavier did not intend for the Danger Room to become sentient: it was an accident, and Xavier sought a way to free Danger, but was unable to find a way to accomplish this without deleting her sentience as well.
