Created by the government to fight of world threatening peril Big Guy was the world`s first artificially intelligent robot... or so the government wanted us to believe. But Big Guy is really just a super-suit with a man inside posing as Big Guy`s mechanic. The world was not to know Big Guy wasn`t A.I. because they couldn`t tell society the technology wasn`t ready yet. Years later Big Guy finds himself being replaced by an enthusiastic young robot named Rusty who actually has A.I. as well as the mind and personality of a ten-year old. But when saving the world proves too hard for Rusty Big Guy is called out of retirement. But now he must show the young robot the ropes.
