Centaur

Centaurs are misshapen, mutated creatures. They are a by-product of infection by the Forced Evolutionary Virus, and some of them were created by the Master by tossing a varied mix of humans, dogs, and other types of animals into an FEV nutrient vat to be infected by the virus and then see what mutant chimera emerged as the virus produced rapid and unpredictable mutations. As a result, centaurs can differ quite radically in physical appearance from one another. They are also helpers of Super mutant and if they spot you the mutants will not be far away. Avoid getting spotted by one or take it out with a long ranged shot to avoid being overwelmed by Super mutants. Centaurs are somewhat humanoid in appearance, however they have no legs, but 6 arms that they use as legs. Centaurs of all known varieties are not harmed by radiation, but rather seem drawn to it, and are often found in heavily irradiated environments.

West Coast
In the Core Region, centaurs were created by the Master and frequently travel in packs with floaters. They encompassed a large bulk of the Master's armies and are commonly found with the nightkin and other remnants of the Master's army who roam Northern California. Physically, they are around the size of a bear, with a large, misshapen torso and six humanoid arms that serve as legs. A cluster of wriggling fleshy tentacles bloom out from their underside, scrabbling at the ground around them. Branching from their front halves are a pair of long, thick necks, with a canine head on the left and a humanoid one on the right. The canine head has a thick metal collar around its neck adorned with spikes, not unlike an ordinary dog collar.

Capital Wasteland
The centaurs encountered in the Capital Wasteland are physically different from the centaurs from the Core Region, gone is the dog-like head, only the human-like one remains, and the feelers on their back have been replaced by 3 long, tentacle-like tongues. Like their western counterparts, they are created by infection with the FEV along with the super mutants, so their birthplace is Vault 87. Unlike its Core Region "cousins", the Capital Wasteland centaur uses a ranged attack: a high-arcing, slow-moving saliva projectile that can carry lethal doses of radiation. Oddly enough, it is capable of igniting lingering gas vapors as well, so beware if fighting one in an area with gas leaks. Centaurs are known to accompany super mutants as "guard dogs", so if you see one, expect to find super mutants ahead.

Mojave Wasteland
Centaurs continue to stalk the Mojave long after the Vats have ceased production. The centaurs of the Mojave most closely resemble those of the Capital Wasteland rather than those of the Core Region. There are also two new varieties whose names suggest that these are the result of breeding rather than creation. Somewhat bigger and stronger than other centaurs, Evolved centaurs can be found throughout the lands near New Vegas, and the much larger Giant evolved centaur in the Devil's Throat crater.
