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 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. Her favorite food is pizza, specifically pizza Margherita, and she is shown eating pizza during her first appearance in the series and in two later appearances.
While she may have bad manners, she has some common sense. 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 where in her "older brother" got "killed" from the Noble's initial shot in order to prevent an Admiral from coming to the island.
Bonney also believes in the stereotypical view of what a pirate should be. While she saved Zoro from attacking a World Noble, it was to protect her own skin. She, however, refused to help an innocent man who was shot earlier by the same noble. Her reason for doing this was that the man was a stranger and she was a pirate, and while Zoro was also a stranger to her, he himself is a pirate.
Several instances suggest that she has an unforgiving disposition towards those who wrong her. While she kept Zoro from attacking Saint Charloss, Luffy later attacked him, so an admiral was sent to the island anyway. She has since built a grudge against the Straw Hat crew. She swears that she would wipe the crew out if they met again in the New World for the incident at the Sabaody Archipelago. She also appears to have a grudge against the Marines or the World Government as seen when Akainu captured her, saying that she will never forgive them.
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. As a result of this ability, accurately determining her true age is difficult. 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.
