Zona

Zona is a quiz researcher who was born in Arabasta. She created the Grand Line Quiz ("偉大なる航路" クイズ), with questions about locations in the Grand Line, and travels to different islands to popularize it. She appears in One Piece Odyssey.

Appearance
Zona is a young girl with fair skin, and large eyes. As a child, she had pink, braided hair and wore a red checkered dress, a yellow vest, and sandals.

As an adult, her hair is down to the middle of her back, and she wears a yellow shirt with white dots and a striped green skirt.

Personality
Zona describes herself as a wondering scholar. She is very observant and is skilled at guessing where people are from. She is very knowledgeable of different climates and folklore of regions around the world, as well as of desert species.

One Piece Odyssey
When the Straw Hat Pirates approached her in the Sandy Oasis, Zona made a proposal to Luffy and his crew. She eagerly asked them quiz questions, including one about a poisonous spider called the Desert Strawberry.

She appears again as a fully grown adult in the Water 7 Memoria. After rescuing Usopp and Franky from CP9, the Straw Hats run into her south of Galley-La Headquarters. While not recognizing her at first, they end up responding to her questions again, though the third challenge takes a new form involving finding her based on a hint.

Trivia

 * Upon encountering her in Water 7, the Straw Hats are taken aback by her seemingly rapid aging as she was just a child back in Arabasta, though Sanji states "There are women in the world who grow from child to adult with incredible speed. It must be common in this part of the world!". However Usopp doubts the validity of Sanji's statement.
