Her surname has never been revealed, probably as a nod to her voice actress, Raven-Symoné, who is generally known by just her first name. The character’s design has evolved through the seasons, with the most notable change being to her eyes. In Season 1, when she first met Kim, she had small pupils, but starting from Season 2, her eyes became wider and fuller. She is a close friend of Kim's, and by far one of the most "normal" people in Kim's life.
