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 generally assumed to be 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, mutants have actual genetic mutations.
Background
A March 1952 story in Amazing Detective Cases #11 called "The Weird Woman" tells of a woman describing herself as a mutant who seeks a similarly superhuman mate. Roger Carstairs, a mutant who can create illusions, is shown in Man Comics #28, dated September 1953. A character with superhuman powers, born from a radiation-exposed parent, was seen in "The Man with the Atomic Brain!" in Journey into Mystery #52 in May 1959; although not specifically called a "mutant", his origin is consistent with one. A little-known story in Tales of Suspense #6 titled "The Mutants and Me!" was one of the first Marvel stories to feature a named "mutant". Tad Carter, a mutant with telekinetic powers, is shown in Amazing Adult Fantasy #14, dated July 1962. The modern concept of mutants as an independent subspecies was created and utilized by Marvel editor/writer 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. These mutants first appeared in the superhero series X-Men, which debuted in 1963. Marvel later introduced several additional mutant superhero teams, including The New Mutants, X-Factor, Excalibur, X-Force, and Generation X. 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.
Omega-level mutants
An Omega-level mutant is one with the most powerful genetic potential of their mutant abilities. The term was first seen in the 1986 issue Uncanny X-Men #208 as "Class Omega", but was completely unexplained beyond the obvious implication of it referring to an exceptional level of power. The term was not seen again until the 2001 limited series X-Men Forever. For a time, no firm definition was offered in the comics, leading to several conflicting opinions and debates as to who or what qualified as Omega-level. In July 2019, Marvel provided an official definition in the X-Men relaunch starting in House of X by Jonathan Hickman : The following are the known Omega-level mutants as of the House of X relaunch: Jamie Braddock, Iceman, Elixir, Jean Grey, Legion, Magneto, Proteus, Mister M, Storm, Exodus, Quentin Quire, Franklin Richards, Vulcan, Hope Summers.
''"Homo superior superior"''
Introduced in Chris Claremont's X-Treme X-Men, a character known as 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.
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. Gideon, Selene, and Apocalypse are examples of Externals.
Cheyarafim and Neyaphem
Cheyarafim and Neyaphem first appear in Uncanny X-Men #429. According to the character 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 which 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. The X-Man Angel is said to be descended from Cheyarafim, while Nightcrawler is supposedly the son of a Neyaphem, Azazel.
Dominant Species/lupine
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, Romulus, claims that some human mutants evolved from canines instead of primates. Mutants who are a part of this group include Romulus, Wolverine, Daken, Sabretooth, Wolfsbane, Wild Child, Thornn, Feral, and Wolf Cub, with X-23 and the Native as other likely candidates. These groups appear to be one and the same.
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.
As a fictional oppressedminority, mutants are often used as extended metaphors for real-world people and situations. In 1982, X-Men writer Chris Claremont said, " 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 filmX2, where Iceman's mother asks, "Have you tried not being a mutant?" This question is common among parents who find out their children are gay. In the 2011 film , Hank McCoy, upon being outed to 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:

Earth X
Within the Earth X universe, the powers of the vast majority of Marvel's human superheroes were revealed to have been the result of genetic manipulation by the Celestials millions of years in the past.
In the UltimateMarvel universe within the pages of the Ultimate Origins #1, it is revealed that super-powered "mutants" were artificially created via genetic modification by the Weapon X program in a laboratory in Alberta, Canada in October 1943. The project was an attempt to produce a supersoldier, inspired by the existence of Captain America. James Howlett was the first individual to be so modified. At some later point, possibly during a confrontation between Magneto and his parents, the mutant trigger was released into the environment worldwide, leading to the appearance of mutants in the general population. Following the events of the Ultimatum storyline, information concerning the origins of mutancy was made public and steps were taken in the US to make being a mutant illegal. While the move apparently has majority support among the non-mutant population, a vocal minority has voiced concern that it will lead to witch-hunts and genocide.
