"It's huge. How do you defeat it?"
Aloy, seeing a Sawtooth for the first time with Rost.

The Sawtooth is a machine in Horizon Zero Dawn. It is a medium-sized Combat Class machine, one of the first known machines of this class. It was developed by the artificial intelligence (AI) HEPHAESTUS as a graduation in its efforts to protect Zero Dawn terraforming machines from human predation.


Unlike the Zero Dawn terraforming machines, which were designed and controlled by Zero Dawn’s governing AI GAIA, the Sawtooth was designed by HEPHAESTUS, which had previously manufactured the machines under GAIA’s direction. When GAIA self-destructed,[1] HEPHAESTUS gained absolute control over machine design and management as well as the manufacture of at least 11 known Zero Dawn Cauldrons.

Hostile toward humans for their predations on the terraforming machines for parts and resources, HEPHAESTUS made the machines hostile to humans, a phenomenon the tribes call the Derangement, with Watchers as lookouts against hunters. It then began producing Sawtooths and other combat machines as the next logical step in protection.

The first recorded encounter with a Sawtooth was during the third year of Sun-King Jiran's reign, where Khuvam, Hawk of the Hunters Lodge, was called by the Prefect at Daytower to slay whatever ripped his best cohort limb from limb. For four days, he tracked the machine through the Sacred Lands before finding it. Fighting from twilight to midnight, Khuvam managed to destroy it, surviving with his left arm chewed ragged at the joint. Thus he named the machine Sawtooth as he took his trophy from its shattered remains.[2]

Years later, the Sawtooth became known to the Nora, as they attacked villages and hunting lodges, killing and maiming many Braves, who worked diligently to eliminate them.[3] Rost gave Aloy the task of killing a Sawtooth as her final test before the Proving.[4]

Sawtooths used to be among the machines found in Desert Tenakth territory, but have since been replaced by Ravagers and Thunderjaws.[5]


HEPHAESTUS appears to have modeled the Sawtooth after Smilodon fatalis, an extinct feline apex predator of the Pleistocene epoch, commonly called the saber-toothed cat. Like the saber-toothed cat, it is heavyset at the front, with a large, broad chest, neck, and shoulders, powerful legs, and no tail. Its mouth is equipped with a pair of curved, scimitar-like serrated spikes, like a saber-toothed cat's fangs. Two optical sensor arrays are located on its face, in the same position as a saber-toothed cat’s eyes. Each is composed of two sensors in a vertical configuration. A long, metal crest-like structure runs along the forward area of its back, and an array of three long antenna-like structures protrude from its back in a fan-like pattern, just behind the shoulders. Its paws are equipped with non-retractable claws. The shoulders, head, and neck are heavily armored. A power cell sits atop its hindquarters, and a canister of Blaze is ensconced in its chest.


Sawtooths are usually deployed singly or in groups of up to three to protect herds of terraforming machines such as Grazers and Lancehorns. While the terraformers are busy working, the Sawtooth patrols around the herd, on a constant lookout against perceived threats. The distinctive, heavy sound of its servomotors and its deep, fearsome growls are easily heard. Frequently they are deployed in tandem with Watchers as a primary threat response, immediately converging on the position of any Watcher that sounds an alarm. They may also be found patrolling circuitous paths near areas that humans use as travel routes, especially if herding terraformers are in these areas.


"An entire lodge, wrecked?"
―Aloy, surveying the carnage wrought by Sawtooths

Despite its size and heavyset chassis, a Sawtooth is highly agile and is capable of great speed. It is designed for rapid sprinting and pouncing, and will very quickly close the distance to an identified threat. Sawtooths carry no ranged weapons, but their speed and ferocious melee attacks effectively compensate for this. However, they are highly vulnerable to weapons that utilize fire. Their attacks center on lunging with violent claw slashes and bites, giving enemies little time to retaliate.

  • Sawtooth is known for being the very first boss in the Horizon series.
  • Despite Rost telling Aloy that machines can communicate non-vocally, Sawtooths roar and growl like a lion.
  • If significantly damaged, Sawtooths will begin limping, holding up one of their front paws in a manner similar to cats. Their 'panting' will also become less regular, further indicating their injury.
  • During the game's development, Sawtooths were referred to as "Greywolves."[6]
  • In Ratchet & Clank: Rift Apart, there is an Easter Egg that the RYNO 8 has a chance of summoning the Sawtooth.
  • Sawtooths are one of the few machines from Horizon Zero Dawn that did not reappear in Horizon Forbidden West. Despite this, they were mentioned.[5]
  • According to Special Item descriptions in Acquired Taste, Sawtooth blood is "clear" and "acidic".
