Thunderjaw

The Thunderjaw is a category of machine in Horizon Zero Dawn. It is a large Combat Class machine, one of the two largest known machine of this class. Like other combat machines, it was designed and developed by the artificial intelligence (AI) HEPHAESTUS due to its hostility toward humans for machine hunting. Its size, power, and array of highly damaging attacks make it the most feared machine among the tribes, so much so that it has attained an almost legendary status.
