Valerie has a black curly bob, brown skin and black irises.
Her primary wardrobe is a purple sleeveless short dress with a pink long sleeve button shirt underneath with a matching collar and purple flats. She also wears a belt to match her dress.
In the musical sequences, she wears a rock band suit and she plays the tambourine.
In Josie and the Pussy Cats in Outer Space and like Josie and Melody, Valerie wears a golden yellow space suit with an orange sailor collar and a matching belt with the Pussycat buckle and brown boots.
Valerie uses her genius intellect to help the gang solve mysteries and subdue villains, much like Velma Dinkley before her and Dee Dee Skyes after her. She also has a doppelganger named Princess Milwila.
She is notable for being the first black female lead in a Hanna-Barbera animated TV series or in any other TV cartoon.
