Quote1 We're mutants. Born different from baseline humanity, with an enhanced genome that gives us super-powers. You piss us off at your peril. Quote2

Powers and Abilities




Average Strength level



Variable. (Examples include various weapons and technology designed to disable and/or kill mutants, diseases such as the Legacy Virus or HX-N1 and a lack of control over their powers.)

They can also be affected in deleterious ways by Terrigenesis (please consult this page for more information).

Mutant Biology

Mutants, despite their human origins, have many distinctive traits in regards to biology, physiology and genetics from their evolutionary predecessors. Mutants can have wildly varying biologies depending on the nature of their mutation.


Mutation is caused by the X-Gene in the mutants' DNA. Mutations normally manifest themselves during puberty, often as a result of a traumatic event. Some mutants exhibit their mutations at birth, however, while others do not manifest their powers until adulthood. Secondary Mutation is a phenomenon in which an existing mutant gains additional powers, or a change in their appearance due to a second mutation.

Breeding & Cross-Breeding

Mutant breeding has notable implications, regarding the transmission of the mutant genome, or to hybridisation with others of human or extraterrestrial species.

Alternate Reality Versions


Across the Multiverse, many incarnations of mutants exist. The most recorded ones are similar or presumably similar to the Earth-616 mutants with Homo sapiens evolving into Homo sapiens superior (commonly called Homo superior ), by the activation of an X-Gene in their genome from different sources. In other timelines, they are known as Homo mutandis (The Changed Man) on Earth-889,[7] or Mutantur (The Changing Ones) (also called Witchbreed) on Earth-311.[36] On Earth-2301, mutants are called Homo superior, but telepathic mutants are referred to as Homo sapiens supreme.

On Earth-58163, they are called either Homo superior[41] or Homo mutatis.[10]

They are also called Homo mutatis in the possible future of Earth-4935.[8][9]


While in most Marvel universes the X-Gene was presumably a result of modifications on early man by the Celestials, in the Ultimate Universe the X-Gene is a creation of the US government weapons project in Canadian facilities. This reality's Wolverine was the first of these mutants, and was called the Mutant 0. This mutation is similar to a virus, infecting the population slowly and turning them into mutants.[50]

Genetics Settings

Other mutants, such as those from Earth-89149, differed from mutants on Earth-616 in that their X-Genes are not on the 23rd chromosome but instead on the 13th chromosome. Those mutants weren't affected by M-Day and were invisible to Cerebra's detection, as it was only capable of locating a protein produced on an X-Gene in the 23rd chromosome. It was stated that it was possible that the 13th chromosome carrying the X-Gene had been genetically created for the scouts to stay hidden from devices such as Cerebra, but this statement was considered less possible as the alternate reality origin of those mutants was confirmed.[51]


In realities where others species rather than Homo sapiens ascend as the dominant species, mutants still exist, as most of them are multiversal counterparts to their human alternates.

It should also be mentioned that the Acanti-like Xavier,[52] the Xavier demon,[53] and the giant squid-like Xavier exist, although it is unknown if those Xaviers were exceptions in their home-realities.[54]


The mutants can be divided into multiple categories, regarding to their origins, genetic status, powers, etc.


Habitat: Earth, primarily on Krakoa. Formerly concentrations at the Jean Grey School for Higher Learning, New York City; Utopia; San Francisco Bay, California; Genosha; Neverland, Canada; Mutant Town, New York
Gravity: 9.80665 m / s2
Atmosphere: Roughly 78.09% Nitrogen, 20.95% Oxygen, 0.93% Argon, 0.038% Carbon Dioxide, and small amounts of other gases.
Population: Less than 200 before the Avengers vs. X-Men.

The mutant population of Earth-616 has varied greatly, climbing to millions and decreasing to a few hundred individuals.


Type of Government: Individuals and groups among human societies. Independent groups have oligarchic-based governments.
Level of Technology: Similar to humans.
Cultural Traits: Similar to human culture, yet with an unique subculture: Mutant Culture.


  • There is a clear distinction between mutants and mutate humans.
    • Mutants are a species evolved from Homo sapiens sapiens and known as Homo sapiens superior. They are distinguished by the presence of an X-Gene.
    • Characters who gained their superhuman powers from other sources such as radioactive spiders, gamma radiation, cosmic rays, magic, Super-Soldier Serum, etc. are NOT mutants. They are mutated humans.
    • The term mutant is often confused to intend or designate mutate, both by characters and by authors.
    • In the same way, they are sometimes confused with the Inhumans (another humanity off-shoot) or with the Warpies, children and babies mutated by unstable extra-dimensional energies. Those two kind develop random powers and appearances, as the mutants.
  • It is a matter of debate and interpretation as to whether or not mutants can still be considered as human:
    • Some believe mutants are humans,[57][58][59] humans with an X-Gene,[citation needed] or a special kind of human.[citation needed]
    • Others, humans or mutants, feel that mutants aren't humans, with or without also believing in mutant or human supremacy.[60][61]


  • When asked if there was a way to distinguish Inhumans from mutants, Tom Brevoort (presumably joking) stated that all Inhumans were left-handed.[62]
