Super Mutant

Super mutant is a general term referring to humanoid mutants created by exposing a human to a variant of the Forced Evolutionary Virus. The resulting hulking mutants typically possess exceptional strength, endurance, resistance or immunity to disease and radiation, as well as modified intelligence. Originally introduced in Fallout as a unique mutant menace led by the Master, super mutants have appeared in every game since, in several varieties and playing a variety of roles.

Fallout Shelter and Fallout Shelter Online
Super mutants also appear in Fallout Shelter.
