Spawning a terrible live-action movie, Inspector Gadget will have you whistling the theme tune just by saying the shows title. Originally made in the 80s, Inspector Gadget ran the whole way through the 90s as well. You would need to have never been near a TV to miss the metallic detective. Gadget is a hapless bionic-cop. Incompetent and clueless, Gadget relies on the help of his niece Penny and their intelligent, talking pet dog Brian (long before Family Guy). Dr. Claw is the trios nemesis; though you never get to see his body, only his metal hand and his pet cat (Blofeld style). Penny and Brian help Gadget battle Claw and his M.A.D agents; often leading themselves into dangerous situations, and always ending with the same results: Claw gets away but the day is saved. A great mixture of action, adventure and comedy Inspector Gadget doesnt take itself too seriously. While not as gritty as some of the other cartoons on the list, it is probably one of the most recognizable.
