S01E01 Don't Call Me Gadget!
Colonel Nozzaire (pronounced Nosehair according to the Colonel) is captured by aliens who think that he is Gadget. They do tests to see if he is Gadget, which he fails. Gadget tries to find him,...
Colonel Nozzaire decides to follow his therapist's advice about reducing his stress level and fires Gadget but Gadget thinks he's being sent undercover. After a couple of disastrous menial jobs, he's hired by a Temp agency that's a front for MAD to send him to do their dirty work under the guise of doing odd jobs.
Having been recruited by an elite international peacekeeping group called the World Organization of Mega Powers (WOMP), Inspector Gadget is now Lieutenant Gadget, and fights crime with a pair of mechanical assistants called Gadgetinis, who are small robot versions of the Inspector created by his niece, 12-year-old Penny (due to Brain retiring from active duty).
