From Wikipedia, the free encyclopedia


Penny is Inspector Gadget's niece, she has blonde hair worn in pigtails and green eyes, wears a red and white shirt, green pants and red shoes. Compared to her obtuse Uncle, Penny is a master amateur detective and technology expert who always solves the cases her Uncle is assigned. Gadget, her uncle appears to be her legal guardian, and her parents are never mentioned.

Penny has a few gadgets that she uses to help her uncle. She has a computer book which assists her in looking up information and overriding electronic (and occasionally even mechanical) devices, and a wristwatch with a laser beam, communicator, which she uses to call Brain and Chief Quimby, and Gadget.

Penny often carries a tote bag and inside it carries her computer book. In episode "Luck of the Irish" Penny carries a backpack, instead of a tote bag. Usually, she doesn't have a tote bag or backpack.

While Gadget is on duty, Penny sends Brain to keep an eye on him while she tries to solve the crime. Penny usually investigates the clues and discovers the M.A.D. plan. Penny very often solves the cases while using her computer book or changing the thing which M.A.D is going to steal into a fake. Furthermore, she is able to accomplish these tasks so subtly that not even the criminal mastermind, Doctor Claw, is aware she is the actual continual threat to his plans.
