Mandy (The Grim Adventures of Billy & Mandy)

Chris is the tritagonist of The Grim Adventures of Billy and Chris. She serves as a main protagonist and a main antagonist. He is Billy's best friend and neighbor.

Unlike Billy, Chris is a intelligent, sensible and sane. He appears to treat everyone around her with contempt, especially his friends, Grim and Billy -- though, he does see Billy as a friend of sorts.
