About the size of a common draft horse, the Strider very closely resembles a heavy-built horse in terms of a body. They stand on four horse-like legs with hooves and have powerful shoulders. The head, however, more closely resembles that of bovines, with two swept-back horns. Towards the back end above the "rump" is a Blaze container.
Striders were created by GAIA as part of the terraforming process after the Faro Plague wiped out all the biomass on Earth in the 21st century. They likely were made to help balance the atmosphere by producing oxygen or CO2. Striders became very commonplace and, for a long time, were peaceful grazers that shied away from humans if one was spotted.
However, a decade before the game's events, the Derangement took place and the Striders, along with all other machines, began to become more aggressive. They would menace humans that attacked them instead of running away or keeping their distance. By the time Aloy came of age and learned to hunt, Striders would 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.
After Aloy brings down the first Corruptor machine, she takes its equipment and finds that she can use it to take control of a Strider for use as a mount. Thanks to this development, Aloy can now quickly traverse long distances in a short time thanks to the Strider's speed.
Sylens learns of this Override ability by spying on Aloy, and he uses this to not only override two Striders to rescue Aloy from the Sun Ring, but even overrides three Ravagers to cover their retreat.
Like the Watchers that commonly accompany Strider herds, Striders have no weaponry. However, if spooked they can charge towards the perceived threat, knocking them down and trampling them to death.

Striders seem to communicate vocally with horse-like whinnies and neighs, despite machines being capable of non-vocal communication.
