Gadget Hackwrench is one of the main protagonists of Chip 'n' Dale: Rescue Rangers as well as the love interest of both Chip and Dale - though throughout most of the show she seemed largely oblivious to the constant bickering the two chipmunks showed in their attempts to impress her, however later on it was revealed that she gave Chip a photo of herself: which strongly suggests their was a romance between the two.

Gadget herself is an anthropomorphic mouse with a talent for invention and a tendency to say "Golly!" whenever she is surprised - due in part to her incredible genius she bores quite easily and is a prolific inventor, though like many cartoon inventors not all of her inventions go to plan and this has on occassion caused problems for the group.
