In American comic books published by Marvel Comics, a mutant is a human being that possesses a genetic trait called the X-gene. It causes the mutant to develop superhuman powers that manifest at puberty. Human mutants are sometimes referred to as a human subspecies Homo sapiens superior or simply Homo superior. Mutants are the evolutionary progeny of Homo sapiens, and are often referred to as the next stage in human evolution. The accuracy of this is the subject of much debate in the Marvel Universe.
Unlike Marvel's mutates, which are characters who develop their powers only after exposure to outside stimuli or energies (such as Spider-Man, Captain America, Fantastic Four, Hulk), mutants have innate genetic mutations from birth.
Publication history Early antecedents Officially, Namor the Sub-Mariner is considered the first mutant superhero whom Marvel Comics ever published, debuting in 1939. However, Namor was not actually described as a mutant until Fantastic Four Annual #1, decades after his first appearance. The same is true of Toro, partner of the android Human Torch introduced in 1940.
Modern concept and development The modern concept of mutants as a distinct species independent of homo sapiens began development under Marvel writer and editor-in-chief Stan Lee in the early 1960s, as a means to create a large number of superheroes and supervillains without having to think of a separate origin for each one. As part of the concept, Lee decided that these mutant teenagers should, like ordinary ones, attend school in order to better cope with the world, in this case Xavier's School for Gifted Youngsters. Following the 1963 debut of this conception of mutants in the superhero series X-Men, Marvel later introduced several additional mutant superhero teams, including the New Mutants, X-Factor, Excalibur, X-Force, and Generation X.
In early X-Men stories, Xavier and others suggest that mutation is related to nuclear radiation, as his parents worked on the development of the atomic bomb, though later descriptions of mutation would describe it deriving from genetics. The first in-story mention of mutants in this context is in The X-Men #1, in which Xavier explains his school to the newly admitted Jean Grey: "You, Miss Grey, like the other students at this most exclusive school, are a mutant! You possess an extra power...one which ordinary humans do not!! That is why I call my students...X-Men, for Ex-tra power!"X-Men #1 (September 1963) This issue also features the first reference to mutants as the species "Homo Superior" by Magneto. Following the relaunch under writer Chris Claremont, narration in stories taking place on Muir Island described Moira MacTaggert as "second only to Charles Xavier as an authority on genetic mutation."Uncanny X-Men #125 (September 1979) In the New Mutants graphic novel, after witnessing Wolfsbane demonstrate her mutant shapeshifting ability, MacTaggert refers to "an anomalous DNA matrix" in her blood signaling that Wolfsbane "could be a mutant."Marvel Graphic Novel #4: The New Mutants (November 1982) The cause of mutation was elaborated upon in the first issue of the spin-off series X-Factor, in which Cameron Hodge refers to "people who possess the X-Factor mutation in their genetic makeup."X-Factor #1 (February 1986) This genetic mutation was later dubbed the X-Gene. At one point, Beast states that the X-Gene is located on the 23rd chromosome;Astonishing X-Men (vol. 3) #25 (September 2008) the process described is that the gene activates mutation producing a protein stimulating chemical signals which induce mutations on other genes.Astonishing X-Men (vol. 3) #27 (November 2008)
Mutations are depicted as generally manifesting during adolescence,New X-Men #118 (November 2001) however this is not universal. Some mutants, such as Nightcrawler, are visibly mutated from birth,Uncanny X-Men #177 (January 1984) while others like Magneto do not develop their abilities until adulthood.Classic X-Men #12 (August 1987) Some mutants are not even aware of their latent mutations unless deliberately activated, such as Polaris, whose manifestation was triggered with technological aid.X-Men #50 (November 1968)
Later developments In the 2022 storyline, A.X.E.: Judgment Day, mutants are discovered by Eternals to be an offshoot of the Deviant race, triggering efforts by the Eternals' leader Druig to wipe them out, giving the mutants an explicit link to the Celestials and to the publisher's cosmic storylines.
Mutant Subtypes
Omega-level mutants
Changelings Introduced in the second series of X-Factor, a changeling is a mutant whose powers manifest at birth. Jamie Madrox and Damian Tryp are examples of this sub-class.
Cheyarafim and Neyaphem Cheyarafim and Neyaphem first appear in Uncanny X-Men #429. According to Azazel, the Cheyarafim are a group of angel-like mutants who were the traditional enemies of the Neyaphem, a demonic-looking group of mutants who lived in Biblical times. The Cheyarafim were fanatics who had a strict, absolutist view of morality that led them into conflict with the Neyaphem. This escalated into a holy war, causing the Neyaphem to be exiled into an alternate dimension. What happened to the Cheyarafim after this has not been revealed.
Angel and Icarus are said to be descended from Cheyarafim,Marvel Zombies: The Book of Angels, Demons & Various Monstrosities (September 2007) while Nightcrawler is supposedly the son of a Neyaphem, Azazel.
Chimeras Introduced in "House of X and Powers of X", the Chimeras are genetically altered humanoid mutants who are combined from the DNA of past mutants so that they would have combinations of their power set and also propagate the mutant population. Third generation Chimeras have a 10% failure rate, making them unable to be warriors. Fourth generation Chimeras have a corrupted hive mind. Chimeras are commonplace in Moira MacTaggert's ninth life, where they are created by Mister Sinister.Powers of X #1 (September 2019)
Dominant Species/Lupine Maximus Lobo claims to be a part of a mutant sub-species of feral wolf-like mutants, whom he calls the Dominant Species. He later tries to recruit Wolf Cub into his ranks to no avail. A few years later, another mutant named Romulus claims that some human mutants evolved from canines instead of primates. Romulus' sister Remus would later consider his claim to be a hoax when she meets Wolverine.Wolverine (vol. 2) #312 (October 2012)
Daken Feral Romulus Sabretooth Thornn Wild Child Wolf Cub Wolfsbane Wolverine
Externals Created by Rob Liefeld, Externals are immortal mutants whose powers have allowed them to exist for centuries. Eventually, most of the Externals are killed by Selene, and later by Apocalypse.
Absalom Burke Candra Crule Gideon Nicodemus Saul Selene Apocalypse
"Homo superior superior" Introduced in Chris Claremont's X-Treme X-Men, Vargas claims to be humanity's natural response to mutants. Vargas was born at the epitome of peak physical skill, having superhuman levels of strength, speed, reflexes, agility, stamina, and durability. Vargas also seems to be immune to various mutant abilities (such as Rogue's absorption and Betsy Braddock's telekinetic blast).X-Treme X-Men #2 (August 2001)
Hybrids Mutants have been shown to successfully crossbreed or a result of crossbreed with humans (Homo sapiens), Atlanteans (Homo mermanus), fairies, and other humanoid aliens like Shi'ar, etc.

Other mutations Children of the Vault: A species of super-powered beings created from a temporally accelerated cargo ship. They are genetically distinct from humans and mutants. Neo: A secluded race similar to mutants with far stronger abilities. Rao Factor: Kavita Rao at one point examined Cindy Shears (Rhinoceress), a girl with a mutation "adjacent but legally distinct" from the X-Gene. Rao dubbed this the "Rao Factor".
Mutants as metaphor
As a fictional oppressed minority group, mutants are often used as extended metaphors for real-world people and situations. In 1982, X-Men writer Chris Claremont said, "[mutants] are hated, feared and despised collectively by humanity for no other reason than that they are mutants. So what we have here, intended or not, is a book that is about racism, bigotry and prejudice."
Danny Fingeroth writes extensively in his book Superman on the Couch about the appeal of mutants and their meaning to society:
An obvious parallel between homosexuality and mutation is drawn in the feature film X2, where Iceman's mother asks, "Have you tried not being a mutant?" This question (or various forms thereof) is common among parents who find out their children are gay. In the 2011 film X-Men: First Class, Hank McCoy (later known as Beast), upon being outed at a colleague as a mutant, responds, "You didn't ask, so I didn't tell."
In his article Super Heroes, a Modern Mythology, Richard Reynolds writes:
Other versions Earth X Within the Earth X universe, the powers of the vast majority of Marvel's human superheroes are the result of genetic manipulation by the Celestials millions of years in the past.
Ultimate Marvel In the Ultimate Marvel universe, the mutant gene was created by Weapon X, with James Howlett being the first mutant. At some later point, possibly during a confrontation between Magneto and his parents, the mutant trigger was released worldwide.
In other media X-Men film series
Mutants appear throughout the X-Men film series and animated media and games based on X-Men produced by 20th Century Fox, most of which closely adhere to the comic book explanations of mutant origins as humans born with a genetic difference that gives them special powers, the fact of which engenders discrimination from other humans due to the pitfalls of human nature. One liberty the films often take with X-Men characters is to simplify non-mutant characters in the X-Men franchise into mutants for simplicity's sake, as was the case with Deadpool and Juggernaut in the film series.
Marvel Cinematic Universe
Following The Walt Disney Company's acquisition of 21st Century Fox in 2019, the film rights to the X-Men and other mutant characters reverted to Marvel Studios. When asked if his use of the term "mutants" meant the film would be avoiding the term "X-Men", Marvel Studios president Kevin Feige clarified that he was using the two terms interchangeably. He added that Marvel Studios' approach to the characters would be different to Fox's franchise. Since 2022, members of the mutant race have appeared in various media set within the Marvel Cinematic Universe (MCU) media franchise:
Mutants are first implicitly introduced through a variant of Charles Xavier from the alternate universe Earth-838 in the film Doctor Strange in the Multiverse of Madness (2022). Patrick Stewart reprises the role from Fox's X-Men film series. The first mutant belonging to the main reality of the MCU is Kamala Khan / Ms. Marvel (played by Iman Vellani), which is stated in the final episode of the television series Ms. Marvel (2022). This differs from the comics, where Khan is an Inhuman. A musical excerpt of the X-Men: The Animated Series (1992–1997) theme is featured in both Ms. Marvel and Multiverse of Madness. The comics version of Khan was later retconned to be a mutant-Inhuman hybrid to reflect the MCU.
