Jewelry Bonney, also known as the "Big Eater", is the captain of the Bonney Pirates and a South Blue native. She is one of twelve pirates who are referred to as the "Worst Generation". Bonney is a slim woman (despite the enormous amount of food she consumes regularly), with long pink hair and brown eyes (purple in the anime). She can also appear as a small child due to her Devil Fruit ability: In this form, she has similar, although obviously more childish, facial features, and is not as tall nor as buxom as in her adult form.
Her outfit consists of a white low-cut tank top that exposes both her midriff and cleavage, along with a pair of orange-and-black striped buckled shorts with long, thin suspenders. She also wears black high-heeled boots which reach up to her calves, with large laces coming from the openings, and a pair of hot pink and dark red stockings with a yellow sun-like motif on them (a pattern seen other times in the One Piece world). The hat she wears is a green Furażerka with a light-green lining. She has an anti-eyebrow below her right eye, bright red lipstick on her lips, and is sometimes seen wearing a brown furred jacket.
In an SBS section, Oda drew the Supernovas as children. Bonney is shown with shoulder-length hair as opposed to her current back-length hair and a rounder face. Her clothes and face are somewhat dirty showing that since childhood she had a huge appetite.
In Oda's depiction of the Supernovas post-timeskip, Bonney is shown wearing a black hat (possibly a sunhat similar to Usopp's, judging by the rim) with a brown furred coat or cloak. She also uses pink lipstick as opposed to the red one before the timeskip.
Bonney, for some unexplained reason, seems to be able to consume large amounts of food without any adverse effects on her body. No matter how much she eats, she is somehow able to metabolize all the food she ate without becoming full or even remotely fat, quite possibly due to her Devil Fruit powers giving her the metabolism of a child.
Bonney has shown little in the way of physical abilities. She was shown to be quite fast however, as she managed to tackle Zoro before he was able to attack Saint Charloss. She and her crew were overpowered and captured by the Blackbeard Pirates, though she did manage to injure Marshall D. Teach by kicking him in the head. Bonney exhibits unexplained abilities that appear to come from a Paramecia-type Devil Fruit that involves age manipulation. She can alter the ages of herself and others, rapidly aging her intended targets into their senior years or regressing them into small children.[6] As a result of this ability, accurately determining her true age is difficult.[2]
If her power stems from a Devil Fruit, it is rare in that it does not affect the clothing of those she uses it on, though it is natural as clothes do not change in size even as they age. Bonney apparently wears skimpy clothing and suspenders so that her clothes will fit when she becomes a child, while a group of Marines affected by it became too small for their own clothing once aged down to children.
She may need her hands to use her power, as Blackbeard kept her in line simply by chaining her hands to a post, though it is also possible that the chains were lined with seastone, preventing her from accessing her powers.
In the anime, one of these transformations is heard, yet not seen, implying that her powers work through a process, rather than in a flash. She also briefly speaks a line in her adult voice while in child form after saving Saint Charloss from Zoro.
