Mutants can be divided into multiple categories, regarding to their origins, genetic status, powers, etc.
- 1 Hybrids
- 2 Mutant Subspecies
- 3 Possible Previous, Parallel, Future Mutant Species
- 4 Non-Human Mutants
- 5 Artificial Mutants
- 6 Powers-Based Classification

Mutants are known to be able to produce hybrids via breeding or genetic engineering.

- Also see the list of Dominant Species Mutants.
The Externals were a small group of immortal mutants, who posed themselves as a subspecies.
- To be noted that Spider-Man also possesses the insect gene, but is a Mutate and not a mutant. He is not classified as Homo insectus.
- Also see the list of known Homo insectus.
The Neyaphem are a subset of demonic-looking mutants.
- Also see the list of Neyaphem.
Similarly to Maximus Lobo and the Dominant Species creed, Husk theorized that eventually, "Angel" people, "Husk" people, "Wolverine" people, "Ice" people would band together to fight in the war of the "survival of the fittest".
Possible Previous, Parallel, Future Mutant Species
Some species have been claimed to not be subspecies of the Homo superior but species on their own, previous, parallel or future forms of mutants. The accuracy and relevancy of those statements is unknown most of the time.
Homo Killcrop (also known as Changelings, Killcrops or Replacement People) is allegedly a genetic predecessor to Homo superior. Those mutants possesses an X-Gene which manifests at birth instead of during adolescence. It is unknown if Killcrop is indeed a species or a subspecies.
- Also see the list of Changelings.
- Not to be confused with others.
It was stated that Mr. Immortal was not Homo superior, but the first member of the new species Homo supreme, the final step of evolution, apart from both humans and mutants. Although, Craig Hollis presented himself as both mutant and Homo supreme soon after his origin revelation.
- Also see the list of Homo supreme.
- To not be confused with the Homo supreme of Earth-2301, who are the telepaths present within Homo superior, stated to be superior to both humans and other mutants.
The Neo were Homo sapiens superior who lived as recluses and were stated to be stronger, faster, and more powerful than regular mutants. The Neo separated themselves from the rest of mutants and isolated themselves from society for centuries.
- Also see the list of Neo.
- Also see the list of Proto-Mutants.
For one or another reasons, mutants have sometimes been speculated to
On Earth-96585, Homo ultima, the ultimate being, was supposed to be a genetic successor of Homo superior, and a genetic jump from them as far than mutants from Homo sapiens. His gifts were supposed to activate at maturity, and granting his the ability to alter his mutation and choose his powers.
Sean Collins, son of Rusty Collins and Skids, was supposed to be that Homo ultima, but was killed soon after his birth. It was later revealed that he was "normal" (likely mutant) and the whole thing was a plot of Magneto, orchestrated in order to unite his community. As far, Homo ultima remains a lie.
Romulus claimed some human mutants evolved from canines instead of primates.
- Also see the list of supposed Lupine Mutants.
On several occasions, people have tried to mimic, reproduce mutants abilities, or even create their own mutants from human (or species) materials, in creating some way or others X-Genes or powers similar to those granted to them. There is a vast variety of Artificial Mutants, "Pseudo-Mutants, Triploids, "New Mutants", "artificially created mutants", "advanced humans", "fakes", "Freaks".
Also see the list of Artificial Mutants.
- At some point, the C.I.A. proposed to eighteen death-row prisoners to be the subjects of experimentation for becoming mutants. The Bush Rangers were a half-success, as the thirteen survivors had indeed developed shape-shifting abilities, but the mental control attempt on them failed and they had gone rogue. They were all terminated by the media-driven mutant team X-Force.
- All mutants of Earth-1610 and its alternative futures have been developed by the US government weapons project, in Canadian facilities, starting by Wolverine, the very first recorded mutant, the Mutant 0. This mutation is close to a virus, infecting slowly the populations and turning them into mutants.
- After M-Day, Forge created a new kind of mutant to save the mutants race. Using human DNA, cybernetics components and adding extra lots of chromosomes, he created Triploids mutants (with three chromosome of each kind instead of two for regular humans and mutants) with an X-Gene on Chromosome 66. He named them the New Mutants. When Forge launch his invasion plan, he and his mutants were seemingly projected into Earth-89149 threw a Ghost Box or destroyed by a laser blast. Forge somehow survived but no mention was made about his creations. As well as the 13s (see below), the Triploids mutants were invisible to Cerebra.
- Dr. Hayes (the grandmother of Molly Hayes) performed genetic experimentation on her own daughter (Alice) and adoptive son (Gene) to create superhuman powers. After manipulating their DNA, Dr. Hayes was able to artificially create X-Genes in both Alice and Gene granting them identical telepathic mutant powers. Later, Dr. Hayes was able to recreate these same powers within her domesticated house cats.
The mutants classified Code-X (or Code X) are mutants with their X-Genes having turned them crazy. Both Professor X and Spike Freeman used that psychological classification, and both of them considered that as threats who had to be killed.
Doop (without being a confirmed mutant) and Wolverine were both considered as Code-X by Xavier and Freeman, caused by misinterpretation of "symptoms" induced by the Pink Lady illusions. Their condition was referred as Code-X Fever, and they were finally cleared off.
The Genoshan Mutates are mutants (or more exactly, for some of them, humans with latent mutant potential) transformed by the genoshan government and the Genegineer David Moreau as slaves for different purpose, as energy-creators or guards for example.
- Also see the list of Genoshan Mutates.
Most depowered mutants are a result of M-Day. Some depowered mutants results other interventions such as the Hope Serum, power neutralizing guns, or losing powers due to other mutants. Some of these effects are temporary, but others are permanent. Some depowered mutants still consider themselves cultural mutants.
- Also see the list of Depowered Mutants.
A few former mutants were re-powered by various processes.
- Also see the list of Re-powered Mutants
Latent Mutants, or "mutant pre-potentials", are mutants (or individuals claiming to be mutants) who carry the X-Gene in its inactive form and thus do not manifest any powers, or those powers are emerging and are yet to be stabilized. They can be however detected as mutants, using more specialized powers or materials.
- Also see the list of Latent Mutants.
- To be noted that as the latent mutant status is only a transition, and most of those individuals activate their powers sooner or later, very few characters are listed, part of them having been killed before activation.
- Also see the list of Neo-Mutants.
- The Neo-Mutants are not to confused with the Neo, an off-shot of the mutants.
Many classification have been made about the mutants, based on greek-numbered or arabic-numbered scales, mostly unexplained.
Anecdotally, a classification on a genetic basis is also possible.
On an Earth-89149, the mutants possess X-Genes on the 13th chromosome instead of on the 23rd. Those mutants (or "13s") weren't affected by the M-Day, and have superpowers resulting from their mutations.
It was stated that it was possible that the chromosome 13th carrying the X-Gene had been genetically created for the invading scouts of their reality to stay hide from device as Cerebra, but this hypothesis wasn't used since the extradimensional origin of those mutants was confirmed.
Also see the list of 13s Mutants
Some of the mutants from Earth-9047 possess the S-Factor, granting to them, in addition of mutant powers, an amazing raise in the sales of any comic-book starring or guest-starring them (and generating great sales to the X-Persons comics). The villains are concerned as well by this effect, but cannot possess their own series nor gain money from royalties.
Because of the lack of clear informations on Tsu-Zana's nature, it is unknown if the V-Factor concern Kree mutants, or Human mutant/Kree hybrids.
The X-Factor mutants are the classical human mutants or Homo superior: Humans granted with the X-Gene, or X-Factor.
