Super Mutant

Super mutant is a general term referring to humanoid mutants created by exposing a regular human to a variety of the Forced Evolutionary Virus (FEV). The resulting hulking mutants typically possess exceptional strength, endurance, resistance or immunity to disease and radiation, as well as modified intelligence. A common trait of all super mutants is that they are completely sterile and cannot reproduce (one variety is even explicitly asexual, i.e. devoid of primary sexual characteristics). The mutation generally cannot be reversed, as once introduced to the subject, FEV automatically corrects any changes to DNA. A theoretical cure would have to both reintroduce the original DNA and prevent the FEV from overwriting it.

Originally introduced in Fallout as an unique mutant menace led by the Master, super mutants have appeared in every game since, in several varieties and playing a variety of roles.

Mariposa Military Base


Fallout, Fallout 2, Fallout Tactics, and Fallout: New Vegas feature super mutants derived from FEV-II at Mariposa Military Base, who appear as friends, foes, and companions. They are predominantly intelligent, social, and their position in traditional human society is a major question in each of these titles.

In Fallout, they are the creations of the Master, believing the differences that led to the Great War could be overcome through the forced evolution of humanity. The Master's army of Super Mutants (Unity) plans to conquer the wasteland and usher in a new era of peace and prosperity by mutating those worthy of joining and sterilizing those who refuse (unaware of their own sterility). Although ultimately defeated by the Vault Dweller, who destroys Mariposa Military Base and eliminates the Master, the super mutants aren't all hostile and represent a variety of attitudes, especially towards the Master and his grand plan.

In Fallout 2, the remnants of the Unity have reacted in different ways to the Master's defeat; some refused to lay down arms and became raiders, others have joined the NCR Rangers or founded new communities where humans and mutants coexist, such as Broken Hills. The game's super mutant companion, Marcus, is the sheriff of this town. Also introduced is a new, second generation of super mutants, originating once again in Mariposa: The Enclave excavated the base between 2236 and 2237, using captured Redding miners as slaves. Without protective equipment, exposure to the FEV still sealed within the base resulted in uncontrolled mutation. These second generation mutants tend to be, on average, far less intelligent than their peers.

In Fallout: New Vegas, super mutants are rare, but represent another attempt to normalize relations with humans, efforts made possible by the actions of the returning Marcus. The Nightkin are greatly expanded upon in the game, representing the long term legacy of the Master's work: Near-perfect super mutants twisted by years of exposure to stealth radiation, suffering from various psychological ailments. Dealing with the Nightkin and finding a cure for them is a major element of the super mutant story in the game, at Black Mountain, REPCONN test site, and Jacobstown.

In Fallout Tactics, super mutants are the primary opponents in the third chapter, where the Eastern Brotherhood of Steel wars with them across Missouri and Kansas. Organized into Gammorin's Army and led by a rogue paladin, they are remnants of the Unity who fled over the Rockies, and inadvertently woke up the Calculator. They become allies and recruits after Gammorin's defeat.

Vault 87 super mutant


Fallout 3 features super mutants derived from the Evolutionary Experimentation Program (EEP), an FEV derivative used at Vault 87. These mutants are almost invariably hostile, borderline feral, and completely asexual. They act as hostile creatures barely capable of speech or coherent social organization, but are considered a major threat by the Lyons' Brotherhood of Steel, which has engaged them in a war of attrition for nearly two decades by the time the game starts.

Only two non-hostile super mutants appear in the game, Fawkes, a late game companion who also prefers to be called a meta-human rather a super mutant, and Uncle Leo, a randomly encountered traveler. These represent the only non-hostile interactions with them in the entire game. Uniquely, these super mutants never seem to stop growing and ancient, gigantic mutants called behemoths can be encountered. Centaurs are common companions of the super mutants, another hideous effect of EEP mutation.

These mutants also appear in Fallout Shelter.

Institute super mutant


Fallout 4 features super mutants created by the Institute using an FEV sample acquired through clandestine means. These mutants are the byproduct of its research into generation 3 synths, dumped into the Commonwealth. They are somewhat intelligent, forming unique tribes and representing a variety of mostly hostile attitudes.

A super mutant companion, Strong, appears, alongside a handful of peaceful super mutants, providing insight into the communal society of the mutants. Interestingly, the Institute's creations consider themselves both to be superior to humans and their victims, seeing violence as a form of retribution. They are commonly accompanied by other FEV creations, such as mutant hounds and unstable early experiments, the Behemoths.

While a cure for the effects of FEV was speculated by ZAX 1.2, this is the only strain that we have seen cured. Institute scientist, Brian Virgil, is the first we have seen successfully create a serum that recreated his original human DNA while overwriting the FEV present in his system.

Huntersville super mutant


Fallout 76 features super mutants derived from FEV experiments at the West Tek research center in Appalachia, including mass exposure of the denizens of Huntersville and infection of survivors by the Enclave under orders from President Thomas Eckhart, in a desperate bid to increase the DEFCON rating and gain access to the region's missile weapons. Widespread, violent, and hostile, these super mutants have a major presence in the region and are a common enemy for factions that inhabit Appalachia (from past (Responders and Taggerdy's Brotherhood) to present).

Like before, they are accompanied by similarly mutated hounds and floaters. Behemoths, also make a return.

Behind the scenes

 * The name of the super mutants is spelled differently at different points. Despite the fact that "super mutant" is the most characteristic and the most widely used, other variations exist including super mutants, super-mutant, supermutant and mutants. Some mutants in Mariposa in Fallout 2 are called "super duper mutants."
 * While Marcus, the super mutant in Fallout 2, jokes about making prostitutes pregnant if he takes a trip to the Cat's Paw brothel, and remarks that "it only takes a few years to get the juices flowing again" when asked about sterility. Chris Avellone, the author of his dialogue, confirmed it was merely a joke.
