Cappy is the love interest of Rodney Copperbottom in the Blue Sky film "Robots". She doesn't appear in much of the movie. She is voiced by Halle Berry.

At one point, after Rodney tries to confront Phineas T. Ratchet, he is stopped by security bots, from which Cappy saves.

She is shown not to like Ratchet's scheme. She, along with Rodney, Fender, and the latter's girlfriend Loretta Geargrinder, escape from the annual Bigweld Ball (which Rodney and Fender had gone to disguised, where they find out Bigweld cannot attend).
