Master's Army

Master's Army was the military branch of the Unity, composed of normal mariposa super mutants, centaurs, floaters and nightkins, the elite forces of the Master.

History
The Master lamented the needless destruction of the Great War. In order to avoid the self destruction of the species, he desired to forcefully evolve humans into one, perfect race, removing the inequalities that are the cause of strife among humans. If everyone could be as perfect as his super mutants, there would be no more conflict. Those who could not evolve would die. Around 2155, the Master began seeking out uncontaminated humans with which to create mutants in used the Forced Evolutionary Virus (FEV), and build his super mutant army, named the Master's Army. It was the first step of the Unity, his perfect vision of humanity.
