Nefertari Vivi (One Piece)

The princess of the Alabasta kingdom. Vivi met the straw hat pirates while disguising as a spy to protect her kingdom from the pirate warlord of the sea Crocodile. She is a beautiful blue haired girl who is normally happy and cheerful except when Alabasta and her friends are in danger, but today will be an exception as her dignity and grace may take a blow.
