Meet PET!
PET (which stands for polyethylene terephthalate, a type of plastic) was a simple plastic bottle until nine-year-old Noboru Yamada recycled him. Now PET's a SUPER ROBOT programmed to protect Noboru at all costs! Whenever Noboru's in trouble, PET transforms, plugs in, and jets to the rescue! Unfortunately, PET's "help" usually does more harm than good, proving time and again that just because you call yourself "super" doesn't mean you have a clue.
