Lydia Copperbottom is a supporting character in Robots. She is voiced by Dianne Wiest.  
Appearance and Personality
Physical Appearance
Lydia has short, copper-colored "hair", green eyes, and wears a green bell-bottom dress. She seems to have a large lightbulb on her chest.
Personality
Lydia is a very kindhearted housewife, but is also prone to being melodramatic. She was extremely reluctant to let her son Rodney go off on his own, and made every effort to stop him until her husband Herb convinced her that he needed to go. It was hard for Lydia; she was very sad to see Rodney leave. At the end of the movie, Lydia, like her husband, is very proud of Rodney and his accomplishments.
