A mech designed to be the big boss in a video game that is larger, taller, and meaner than any other adversary in the same level.
The base design is an endoskeleton with weapons which was then elaborated into three further progressive levels of heavy armour. The pieces of armour fall off when the mech is attacked, which is then used as a kit bash for the player, allowing him to customize his character and vehicles according to his own specs.
Lower legs also have rocket jump ability using jet engines, allowing the mech to stomp on players.
