he Hashmal is one of the countless model of mobile armors that took the lives of a quarter of the world's population during the Calamity War. Originating from Artificial Intelligence (AI)-equipped self-sustaining weapon developed before the war, mobile armors are independent, unmanned weapons controlled by their own, self-evolution AI. Meant for slaughtering humans, they will move towards areas with high human populations for that purpose. Like the mobile suits that were developed to counter them, mobile armors use Ahab Reactors as their main power source, have a frame made of high hardness rare alloy, and are covered with Nanolaminate Armor, making them difficult to destroy.

Designed for ground use, the Hashmal's limbs are actually arms and can be stored in the shoulders. Despite being larger than a mobile suit, it is much more agile, appearing similar to a bird of prey during attacks. It is armed with a head-mounted beam weapon, a superhard wire blade attached to the back of its head, and a pair of claw-mounted kinetic energy shot launchers. It is usually accompanied by multiple small, unmanned units known as Pluma.
