This is a robot created by the Romefeller Foundation made for war without the use of human lives. Essentially its a remote controlled robot that blows things up. It has a shield which can block many types of explosions. This war bot cannot be manually piloted. Its name may be a reference to the fact it does not use a pilot. It also carries a large gun, capable of destroying manually piloted mobile suits and even the original Gundams.
