Charlotte is a happy blue girl. She is fairly optimistic and sees everything as friendly. To Charlotte, fiends are puppies, Clamburg is a wonderland, and Vendetta is her best friend. She has a fascination of Vendetta, an evil girl with a special power of making fiends. Charlotte does not realize that Vendetta's evil or the fact that she is trying to destroy her with the fiends she makes. Somehow when Vendetta unleashes a fiend onto Charlotte, Charlotte always finds a way to make the fiend friendly.
Charlotte loves singing and is always happy, much to Vendetta's dismay. Charlotte lives with her grandmother Charlene. Her parents are said to be astronauts on a space station. Charlotte wears a long dress and she has a ribbon in her hair. Her grandmother and mother both have similar appearances.
