Penny

Penny is Inspector Gadget's 14 year old niece, an inspector in training. She is brave, clever and willing to fight villains. Her only weakness is Talon, Dr. Claw's handsome nephew. But even though she has a crush on him she never lets him get away with his and his uncle's evil plans. Unlike other Inspector Gadget productions, she now joins Gadget in his assignments and despite the title, she is the protagonist.
