Grazers are relatively peaceful machines that resemble deer. They roam the plains in herds and may be accompanied by smaller groups of Watchers for protection.


The overall appearance and size of the Grazer seems to fit that of some kind of cervid, like a deer, reindeer, or elk, and their behavior is similar to such organic animals.

Like Watchers, Grazers have long necks and one big eye on the front of their heads, which are fitted with a pair of metallic antlers. Grazers carry four Blaze canisters on their backs, and walk on four elongated legs similar to those of a Watcher.


Grazers were created by GAIA as part of the terraforming process after the Faro Plague wiped out all biomass on Earth in the 21st century. As their name suggests, they seem to help control plant growth by consuming vegetation. Grazers became very commonplace and, for a long time, were peaceful machines that shied away from humans if one was spotted.

However, a decade before the game's events, the Derangement took place and the Grazers, along with all the other machines, began to become more aggressive. They would often menace humans that attacked them instead of running away or keeping their distance. By the time Aloy came of age and learned to hunt, Grazers would sometimes attack humans on sight, especially if warned first by nearby Watchers. Fortunately, they were not too difficult to bring down and humans learned to stay out of their sight.


Although they will usually flee when attacked by prowling hunters, Grazers may retaliate and face their foes once they pinpoint them by ramming them and using their antlers.

Grazers seem to extract some sort of biofuel from bushes and grasses they graze on, hence their name. This fuel is presumed to be Blaze, due to the four Blaze Canisters on their backs.

  • Grazers are the only machine to have four exposed Blaze Canisters near one another, making them especially susceptible to fire. Hitting these Canisters with fire will cause an explosion nearly powerful enough to kill an entire herd.
