Strains and experiments resulting in their creation include the following:įEV-II (Mariposa) - The standard strain responsible for the initial Super Mutant breakouts.ĮEP Derivative - This inferior strain from Vault 87 had a nasty side effect: people infected with it did not stop growing, with reports of some reaching the size of small buildings.

Used before and after Fallout's Great War in multiple ways, it began as a Super Soldier program of sorts before becoming the full-blown source of Super Mutants.

These creatures were created due to exposure to the Forced Evolutionary Virus, which itself has come in a variety of strains and implementations in the past. In general, a Super Mutant is a hulking humanoid (compared to regular humans, though not all are of equal size) with enhanced strength, physical capabilities, disease and radiation resistances, and more. Appearing in the original game as a unique mutant enemy led by the Master, super mutants have since become more and more varied.
