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 Terrigen Mist (M-Pox) (please consult this page for more information).

Mutant Biology[]

Mutants have many distinctive traits in regard to biology, physiology, and genetics from baseline humans. 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 hybridization with others of human or extraterrestrial species.

Mutant Classification[]

The mutants can be divided into multiple categories, regarding to their origins, genetic status, powers (e.g. Omega Level Mutant), etc.



Earth and Mars (now referred to as Arakko). Formerly concentrations at Xavier's School for Gifted Youngsters (later renamed Xavier Institute for Higher Learning, Jean Grey School for Higher Learning and Xavier Institute for Mutant Education and Outreach), New York City; Utopia; San Francisco Bay, California; Genosha; Neverland, Canada; Mutant Town; Akkaba Metropolis; Krakoa.


9.80665 m / s2


Roughly 78.09% Nitrogen, 20.95% Oxygen, 0.93% Argon, 0.038% Carbon Dioxide, and small amounts of other gases.


The mutant population of Earth-616 has varied greatly. Before the Genoshan massacre, it was at 17.5 million. It was less than 200 after M-Day and before the Avengers vs. X-Men.[54] When the mutant nation of Krakoa was founded, it had risen to 100,000,[55] eventually increasing to 250,000. However, Orchis brought it down to near-extinction levels once more.[56][57] In addition, there are currently less than 1 million Arakkii mutants living on Planet Arakko (Mars).[58]


Type of Government

Individuals and groups among human societies. Independent groups have oligarchic-based governments. Governments created for and governed by mutants themselves.[59][60]

Level of Technology

Similar to humans. Advanced Krakoan and mutant technology.[61]

Cultural Traits

Similar to human culture, yet with a unique subculture: Mutant Culture. Similar to Amenthian culture.[60]


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 Humans (Homo sapiens) sapiens evolving into Homo sapiens superior (commonly called Homo superior ), which started with 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.[13] On Earth-2301, mutants are called Homo superior, but telepathic mutants are referred to as Humans (Homo sapiens) supreme.

On Earth-58163, they are called either Homo superior[50] 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.[62]

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.[63]


In realities where species other than Humans (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,[64] the Xavier demon,[65] and the giant squid-like Xavier exist, although it is unknown if those Xaviers were exceptions in their home-realities.[66]

In the Earth-199999, Namor is a mutant Talokanil.


  • There is a clear distinction between mutants and mutates.
    • Some Mutants consider themselves as a subspecies or species evolved from Humans (Homo sapiens) sapiens and known as Homo sapiens superior or Homo superior. They are distinguished by the presence of an X-Gene. This idea is more popular between the followers of Magneto, the Brotherhood of Mutants.
    • 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 or mutates.
    • 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 kinds 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,[69][70][71] humans with an X-Gene,[citation needed] or a special kind of human.[citation needed] A scientific argument that can be used in this case is that the activation of the X-Gene led to a microevolution, which would mean that a speciation has not yet occurred. The speciation only occurs via macroevolution, a process that takes millions of years and generations via natural selection, what is not the case of the vast majority of mutants in the Marvel Universe, that only started to appear two decades after the end of the World War II (with a few rare exceptions, like Wolverine and Apocalypse).
    • Others, humans and mutants, feel that mutants aren't humans, with or without also believing in mutant or human supremacy.[72][73]

  • When asked if there was a way to distinguish Inhumans from mutants, Tom Brevoort (presumably joking) stated that all Inhumans were left-handed.[77]
