Manufacturing

The Thunderjaw is a huge bipedal machine with features akin to those of a Tyrannosaurus Rex: powerful and bulky legs, a long body, and a heavy tail to maintain equilibrium. Its body features symmetrical weaponry: a laser weapon in its mouth, cannons on its jaws, a radar array on its back, and Disc Launchers on its hips.

Complexity

Like most large machines, Thunderjaws are found alone. Though there are some pairs and a few groups found guarding high-value assets. When undisturbed, Thunderjaws mill about their respective sites, their footfalls an early warning to anyone wandering too close. They are so massive that they can knock over trees just by walking into them.
The Thunderjaw’s huge size, power, an array of weapons, and the capacity to sustain damage make it one of the most formidable machines. It employs a variety of powerful melee and ranged attacks. Additionally, its radar scanner allows quick detection of hunters hiding in tall grass. Unlike that of a Scrapper, which is able to detect only movement, the Thunderjaw’s radar can detect humans regardless of their motion. Thunderjaws have no elemental weaknesses and are resistant to Shock.

Discovery

Unlike the Zero Dawn terraforming machines, which were designed and controlled by @GAIA, the Thunderjaw was designed by the AI @HEPHAESTUS, which had seized control of the Cauldron facilities and begun aggressive countermeasures to the human practice of machine hunting. Thunderjaws are one of the most extreme examples of HEPHAESTUS' escalating attempts to cull the human population, a phenomenon known to the tribes as the Derangement.
