Princess Vi (full name Violet) is the young rabbit daughter of Emperor Fred, and unofficial ruler of Little Tokyo. She is rather spoiled, selfish, crazy, delusional, stupid, and temperamental. She has a tendency to banish all who displease her to Prisoner Island (which is actually a tropical paradise, but she doesn't know it) or, later, Extra's Island. She thinks her way is the only way (which causes problems to everyone and her way doesn't always go her way).
Princess Vi is devoted to her absent mother where their relationship is very unusual and dynamic—-they try to beat each other up when they first reunite. She gets jealous when someone else gets more attention than her. There are a few episodes where the Princess isn't mean, like "The Son of Big Cheese." where she is nice to the baby and she didn't mind letting the baby draw on the Emperor Fred's face.
