Perona is a short young woman with big, round black eyes and asymmetrical eyelashes on the bottom of each of her eyelids that may represent eyeliner. She has long, waist-length, light pink hair that she keeps tied into two pigtails with black and white flower hairpins. She wears a red crown with a black cross on her head, as well as red lipstick and a thick layer of black eyeliner. She wears a long black strapless dress with lavender frills, red high-heeled boots, and a big black top hat with white floral decor. She has a pink bat tattoo on her left bicep and a watch on her left wrist and wears pink nail polish on her fingernails. She still has her signature parasol and also carries a stuffed animal resembling Kumashi with her. Additionally, she wears her hair in multiple spiral braids on the back of her head. Perona has a very young, childlike, and immature personality, frequently acting selfishly and on her own whims. She dislikes people telling her what to do and disobey her will. Despite this, she is normally loyal to Gecko Moria and apparently sees him as a father-like role model, as she was crying to rejoin him after being sent to Kuraigana Island. After Zoro appeared on Kuraigana as well, she tended to his wounds, displaying a willingness to befriend even those she formerly knew as foes and demonstrating that she can be kind to others, despite her normally cruel demeanor. She is very fond of cute things and will only allow someone to work for her if they are cute. Her dream is to create a kingdom where all the cute things in the world have been turned into zombie animals that obey only her. She dislikes Kumashi because, although he is cute in appearance, his voice is not, and thus she prefers him to just be quiet. Her desire for cute things gives her a slightly childish outlook on some issues. She is somewhat playful during combat, threatening to crush Usopp's heart when she was in her ghost form, which nearly caused Usopp to die from fear, and shortly afterward merely laughing it off when revealing that she could not do so. Perona has katsaridaphobia, a fear of cockroaches, to the point of screaming and crying when Usopp covered her with fake ones. She is also somewhat naive, having watched Usopp seemingly lift a 10-ton hammer without questioning whether or not his feat was genuine, and shortly afterward passing out from fear when he attacked her with it, despite not actually being harmed. She is very confident in her Devil Fruit powers being able to defeat anyone. Even when confronted by the powerful and dreaded Warlord of the Sea Bartholomew Kuma, after initially being frozen with fear, Perona quickly regained her confidence and proclaimed that she would defeat him. She is also quite stubborn about using them in combat, having continued to use her Negative Hollows against Usopp even after they proved useless due to his negativity because she believed that his immunity was a fluke. After the timeskip, she has become more mature, although she still carries a teddy bear around, indicating that she is still obsessed with cuteness to some degree. She displayed a grateful side, as she tearfully thanked Dracule Mihawk for letting her stay on his island. Like many others, Perona has her own unique laugh, "Horo-horo-horo-horo-horo!"
