A cartoon about a soldier in a robot suit called The Big Guy who has heaps of skill and on board weaponry is teamed up with a little robot boy named Rusty. The thing is Rusty thinks The Big Guy is an actual robot and doesn't know it's controled by a human. They have all sorts of adventures together fighting evil and saving the world. However, keeping the secret a secret puts The Big Guy into trouble on multiple occations and endangers his life. A good show for kids but older people would lose interest in it after a few episodes.
