The Mutants

The Mutants are a faction and a sub-type of Ghouls, Nightkin, and Super Mutants. They are made up of former U.S. Military Squads that were mutated into semi-sentient humanoids. Some of them also seem to be NCR troopers as well. They are currently found in the Four Corners and have a somewhat large presence in the region.

Their culture appears to be somewhat primitive and they have a Hierarchy of sorts. The majority of them are of average human intelligence though there are some that have been dubed "Cleavers" by the locals and even by some of their comrades, that are more savage and as their name implies, they seem to use cleavers a lot.

The similarity to Ghouls is their wrinkled skin, with most of them having grey or tan skin. There are a few that are about the size of Super Mutants but with white-ish gray skin.
