Monique

Monique is the best female friend of Kim Possible. She was voiced by Raven-Symoné

History
She serves as a conversation friend for subjects Ron has no interest in. She has a no-nonsense attitude, a good eye for fashion, and a good heart.

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.
