Jewelry Bonney

Bonney's personality is not unlike that of an ordinary kid, being playful, energetic and rather innocent. She is sometimes described as "vulgar" due to her lack of maturity contrasting with the adult figure she generally prefers presenting herself as. However, she is not entirely childish, and in comparison to certain older characters like Monkey D. Luffy, she can come off as more reasonable and less simple-minded, even if only slightly.

Befitting her epithet, Bonney is an extremely gluttonous person with very poor table manners. She will, for instance, demand more food even though she has not finished her current meal. She is usually seen eating pizza, her favorite food, even when fighting or on the run. She shares this quirk with her mother, Ginny, who was similarly insatiable when it came to eating.

Bonney has always displayed an aggressive temper and rude attitude, seemingly stemming from her early childhood as a frequent victim of bullying due to her rare medical condition, which prevented her from socializing with other children normally. Still, even at the young age of five, she knew how to be tactful and show restraint, mostly to prevent upsetting her father Kuma. Said mindset extends to this day, as she knows when to fight and when to prevent trouble, particularly in dangerous territories such as the Sabaody Archipelago. When she saw Zoro attempting to attack a World Noble, she orchestrated a scene to fake Zoro's death and prevent an escalation, knowing full well that such a thing would have led to terrible consequences. However, this sense of caution is overwritten when enticing food is involved, similar to Luffy and Chopper.

Being young, Bonney believes in the stereotypical view of what a pirate should be, that being of selfish, violent plunderers (although she still encourages some degree of morality going by her own personal code). For her, all pirates should follow an unspoken agreement of not creating a stir in delicate situations, and that the idea of a pirate helping wounded strangers also leaves her dumbfounded. However, even she is not against losing control of her emotional urges to confront those others would dare not; while she was originally against the idea of defying the World Nobles of Sabaody Archipelago, due to their statuses and the consequences that would be incurred, when she realized that her father's mind was killed on the orders of Saint Jaygarcia Saturn, she did not hesitate in attacking him, ironically disregarding the consequences herself. Several instances suggest that she has an unforgiving disposition towards those who wrong her, holding grudges and cursing their name.
