- "If that machine charges, it will flatten whatever stands in its way."
- ―Aloy, upon sighting a Trampler
The Trampler is a midsized, bovine machine in Horizon Zero Dawn. One of the original terraforming machine types created by GAIA, Tramplers peacefully perform their function. However, if disturbed by a human, they attack with singular violence.
A Trampler is one of the larger GAIA Terraformers. The machine's chassis resembles the body of a very large bovine bull, with a large head and a pair of large horns, a broad, powerful chest and shoulders, sturdy legs and hoof-like feet. Their mouth parts are composed of a pair of insectoid pincers. They have two visual sensors on each side of the face, in the same position as a bovine's eyes. Six power cells and two antenna-like structures sit on the lower back. Under the belly is a large, glowing, armored processing unit.
Tramplers were created by GAIA as part of the terraforming process after the Faro Plague destroyed Earth's biosphere in the mid-21st century. As such, they were one of the first machines encountered by humans as they explored and settled in their tribal lands. They seem to be equipped for mining and processing of soil, with the ability to excavate soil with their horns and to produce explosions by releasing and detonating flammable gases.
For a long time, Tramplers were docile machines that shied away from a human if one approached a herd. However, with the onset of the Derangement, Tramplers, and all other GAIA terraformers, began exhibiting increasing hostility toward humans. By the time the Nora Brave Aloy became an adult, Tramplers were attacking humans on sight or if alerted to their presence by nearby Watchers.
Tramplers will be found in their respective sites, using their horns to dig up the earth; it can be seen flying out in front of them. Soon after their grazing, they will move to a different area to do the same.
As the name implies, Tramplers usually attack by charging at and running over and/or ramming an enemy. Their large size and normally slow, plodding gait belie an ability to run at a speed rivaling that of an athletic human. They can also release an explosive gas within a radius of about three times the length of their chassis and ignite it, causing a highly damaging explosive shockwave.
