Horizon Zero Dawn™ - Thunderjaw , Gromoszczęk

The Thunderjaw is one of the biggest, most dangerous Combat Class machines, equipped with devastating offensive technology and being an average of 24 meters long by 10 meters tall. The Thunderjaw is a huge bipedal machine with features akin to those of a theropod dinosaur, particularly the Tyrannosaurus rex: powerful and bulky legs, a long body, and a heavy tail to maintain equilibrium. As its name suggests, the head of the Thunderjaw features two sets of mechanical components resembling mandibles that spread to the sides whenever it roars. The majority of its body is protected with heavy armor plates, making it difficult to take it down even with explosive arrows; this results in only a few specific weak points for adversaries to capitalize on, including the open, muscle-like circuitry found behind its legs.
