If a One Piece fan were asked about Jewelry Bonney a little over a year ago, they wouldn't have much to say. Back then, she was an underdeveloped Supernova only known for being a woman, controlling people's ages, eating as much as Luffy, and leering or scowling in almost every official image of herself. There were also hints of her being related to Bartholomew Kuma, making a personal enemy out of the World Government, and having business in the New World. Nobody knew what to make of this character for a long time, but the Egghead Arc has changed that.
