Super mutants are created by exposure to the Forced Evolutionary Virus II from the vats of the Mariposa Military Base in California. They represent the finest form of super mutants, far more advanced than their primitive East Coast counterparts created by imperfect strains of the virus.[1]

Background

Super mutants were created by way of the Forced Evolutionary Virus, beginning at West Tek, mutating from humans.[2] In January 7, 2077, FEV research was transferred to the Mariposa Military Base,[2] to continue under the lead of Leon Von Felden and Robert Anderson. Vats of the virus were prepared as a basis for further development and human experimentation, with a near 100% success rate on lab animals, granting an approximately 60% increase in size and potential 200% intelligence increase.[3] The team then created the FEV-II strain, able to create powerful super-soldiers, exhibiting superior physical prowess, resistance to combat damage, aging, and disease, as well as a negligible loss of intelligence and inevitable infertility.[4]

The Master

The vats were rediscovered by an expedition led by Richard Grey, an exile from Vault City.[5] Accompanied by Harold, they managed to crack the base security and infiltrate the lower levels, though their companion Francine was killed and Mark had to be sent back to the surface.[6] However, within the vats, the automated crane crashed into the two, knocking Harold out and flinging Grey into the vat with FEV.[6] Harold later woke up in the wastes outside the base and escaped, though he was already beginning to mutate.[7] Grey, on the other hand, underwent extreme mutation due to prolonged exposure to the virus in the vat. His intellect grew exponentially, allowing him to comprehend even the most complex issues easily.[8] Grey methodically researched FEV, experimenting with animals and eventually, captured scavengers that strayed into the facility. It wasn't until a few failed mutations that he discovered radiation could be a deciding factor in the success of the change, leading him to pick subjects more carefully.[8]

When his Lieutenant was created, he suggested a secondary reason for possible incompatibility. Reviewing available evidence, he concluded that failed mutations in relatively non-irradiated humans are caused by the inoculating effect a mutated FEV released during the destruction of the Great War had on humans it came into contact with. While exposure to the mutated strain wasn't enough to turn the subject into a mutant, it was enough to cause complications with the pure strain of the FEV that would result in the death of the subject. Grey (now calling himself the Master) concluded that prime subjects could be found among Vault populations. Super mutants were sent to uncover sealed Vaults and capture their inhabitants for processing. This move gave the Master unprecedented amounts of human subjects and in 2137 he began to mass-produce mutants. The success rate was only 8-10%, but the Unity steadily grew.[Non-canon 1] Before the arrival of the Vault Dweller many years later, Grey had never been aware that the mutants he was producing were completely sterile.[9]

The number of test subjects was further increased by raids on Hub caravans and the establishment of the Children of the Cathedral in 2156. Captive caravan drivers and zealots underwent processing, both in Mariposa and Grey's seat of power beneath the Cathedral. In his lair, the Master and his staff experimented with the FEV by injecting it into the brains of the subjects (usually the pineal gland, but also the amygdalae or medulla), triggering changes in brain chemistry. These experiments had limited success: four extremely powerful psykers were created, capable of theoretically wiping out the human race.[Non-canon 2][10] FEV experimentation by the Master was abruptly halted in 2162, when he was killed by the Vault Dweller and the vats were destroyed.

The destruction of the Unity and the Master caused the super mutant community to splinter and break apart. Bands of super mutants fled into the wastes in all directions, with charismatic mutants becoming leaders of warbands and even entire armies. The bulk of the super mutants led a disorganized flight northwards.[11]

The Second Generation

When the Enclave went to the Mariposa Military Base to secure a sample of the FEV for their plans to cleanse the world of everyone they perceived as mutants, they brought with them slaves that they kidnapped from Redding. The soldiers were protected from the effects of the FEV, but not the slaves, and they slowly began to transform into the second generation of super mutants. The results were mixed. The second generation were just as big as the first generation if not bigger, but not as intelligent. In fact, some of the first generation super mutants refer to the second generation as "dumb-dumbs".

One of the first to become part of the second generation was Frank Horrigan, a member of the Enclave's Secret Service. He was sent to the Enclave Oil Rig base where he was subjected to painful experiments that made him bigger and stronger than any other mutant. When the scientists learned everything they could from him, they placed him in a suit of armor that also acted as his life support system, effectively turning him into a living weapon. However, the Chosen One destroyed not only the oil rig, but Frank as well, putting an end to their plans to take back the wasteland.

Characteristics

People who were turned into mutants via the Mariposa FEV Would have their skin turn a shade of olive, with their entire body growing huge with more muscle mass being added by the Virus.[12] With warts and skin defects often growing on their face.[13] Those who were unaffected by the radiation of the wastes were of high intellect after turning into mutants,[citation needed] and those who were affected by radiation often came out dumber than when they went in.[citation needed] But those who were turned into mutants could not breed, as the FEV turned them sterile, thus limiting the generations of mutants.[9]

    ZAX 1.2: "{169}{}{The FEV is pre-programmed with introns of corrected DNA appropriate to the proper type of species. It therefore attempts to correct the DNA of the individual.}"
    "{170}{}{However, as the FEV is partially reliant upon the DNA of the individual, and also includes portions of its own recursive code, the effects can be unpredictable.}"

    "{172}{}{In a genetically viable individual, it re-writes portions of DNA, causing accelerated mutation, usually leading to recursive growth due to the FEV's own patterns.}"
    "{173}{}{This recursive growth leads to an increase in muscle and brain mass, but is often accompanied by disfigurement and damage to existing neural patterns, causing loss of memory.}"
    The Vault Dweller: "{174}{}{What potential long-term side effects exist?}"
    ZAX 1.2: "{178}{}{As the FEV causes constant regenerative update to DNA, it would effectively render the subject largely immortal, as cell death would be offset by augmented growth.}"
    "{179}{}{Additionally, as the gametes of the reproductive system consist of 'half-cells' using split DNA, they could be perceived as 'damage' by FEV, which would 'repair' them, rendering the subject sterile.}"
    "{180}{}{However, as my laboratory facilities are damaged beyond repair, this is conjectural. I cannot offer physical proof. You will have to, in human terms, 'take my word for it.'}"
    The Vault Dweller: "{181}{}{Could FEV mutation be corrected with a counter-virus?}"
    ZAX 1.2: "{184}{}{No. FEV does not retain unaltered original copies of the subject's DNA. Only a virus which re-infected the subject with original DNA could reverse the effects. Additionally, there is no known way to remove the FEV itself.}"
