Freeze Bellowback (Horizon Zero Dawn)

The Freeze Bellowback is a machine in Horizon Zero Dawn. It is a dinosaur-like medium-sized machine of the Transport Class. It is one of a pair of “twin” machines; the other machine in the pair is the Fire Bellowback. The two types were likely originally intended to work together for certain terraforming & ecosystem maintenance tasks such as controlled burns. Manufactured at Cauldron XI by the artificial intelligence HEPHAESTUS from designs conceived by Zero Dawn’s governing AI GAIA, Freeze Bellow backs, like all Zero Dawn machines, were under GAIA’s overall control. However, upon GAIA’s self-destruction, HEPHAESTUS, having become an AI itself, gained control of Cauldron XI and thus control over the machines the cauldron manufactured, including Fire Bellowbacks. Hostile to humans due to their hunting of Zero Dawn machines, HEPHAESTUS weaponized Freeze Bellowbacks, turning their ability to generate extreme cold into a dangerous weapon against humans.
