Charlemange is a Colorpoint Shorthair with vanilla fur, a brown tail and brown hair. She wears a lavender shirt with purple cuffs, a purple shirt collar, a purple button, a green tie, and what appears to be a green swan design on her shirt. She also wears blue and red earrings.
Charlemange has a tomboyish personality. Like Hairball, she doesn't like being left behind when the Pound Puppies go on missions or adventures. She is also considerate towards the Pound Puppies as well as her boyfriend, Hairball. She is also an adventurous individual and will help her friends when they are in danger.
Like most cats, Charlemange can climb a tree or a telephone pole, as seen in Pound Puppies and the Legend of Big Paw. She can also sing and dance.
Cathy Cavadini, who provided the voices of Charlemange and Colette, was known as the voice of Blossom in the 1990's TV Series, The Powerpuff Girls and as the voice of Tanya in the 1991 film, An American Tail: Fivel Goes West.
