|Cartoon debut||"The Wheel Deal"|
|Voiced by||Barbara Mamabolo|
Lydia has a light tan complexion and short red hair. She wears red, rectangular-shaped glasses. Lydia wears a lavender, lime, and green t-shirt with a picture of a flower, a purple skirt, white socks, and gray shoes. For playing sports, she wears a red-orange t-shirt with yellow edges/stripes and a yellow number '1', black pants with red stripes on the sides, and white and light blue shoes.
Lydia wants kids to know that even though she's in a wheelchair, she can do what everyone else can do, but in her own way. She likes to draw and design T-shirts. She also likes track, baseball, and basketball.
Connor noticed the Arthur characters were mostly forest animals, but a fox wasn't taken yet. He made Lydia a girl fox because he thought foxes looked feminine. Connor chose Lydia to be in a wheelchair because he wanted people to know that not all people with paralysis were born that way, saying that she dove into the shallow end of a swimming pool when she was seven and a spinal injury paralyzed her from the waist down. However, this idea was not kept in the TV episode, and Lydia specifically says she was born without use of her legs.
A local news interview with Connor from KARE, an NBC affiliate in the Minneapolis-St Paul area, hinted in 2010 that Lydia may become a permanent character on the show. Despite CVS Caremark's 2009 claim that Lydia was planned to be in two additional episodes, these episodes were not actually in development at all. In spite of this, Lydia was planned to appear in season 18, which was over 6 years later. Due to the fact that two seasons were produced at once, Lydia's episode was made part of season 19 instead. This episode turned out to be "Little Miss Meanie".
Lydia has had two last names. In Connor's original entry, Lydia's full name was Lydia Fox. In the voice credits for "The Wheel Deal", her name was changed to Lydia Gordon, presumably in reference to Connor Gordon, though this last name is not spoken in the episode itself. In "Little Miss Meanie", the full name Lydia Fox is said aloud multiple times.
