Appearance Baby 5 is a tall, slim young woman. She wears lipstick, a burgundy French maid outfit with white frills, matching high heel shoes, and various tan belts for carrying weapons. She has been seen smoking a cigarette on multiple occasions and sometimes carries heavy weapons on her back, including a large rifle, an axe, and a sword. She has long black hair, which she wears slightly curled and adorned with a white lace headband.[1]

When she arrived at Punk Hazard, she wore goggles around her eyes, which started filling up with tears when she cried. Upon her arrival at Punk Hazard, she was seen carrying new weapons on her back: a large bazooka and a large Gatling gun.[10]

At eight years old, she had much shorter hair and wore a yellow ribbon on top of it. At 14 years old, her hair seemed less wavy, she lacked lipstick, her hair ribbon was red, and she wore simple brown gloves.

personality Having been abandoned by her mother, who called her "useless" before parting, Baby 5 was left with an overwhelming desire to prove herself useful to anyone, no matter who they were. She is unable to turn down any favors asked of her, and is delighted at the notion that she is needed whenever she is asked to do something, even if the person made it clear that it was a mere joke right afterward, to the point of committing suicide to achieve it.[14]

This behavior can make her want to marry, help, lend money to, or buy things from anybody who asks. She is known to even buy weapons from someone, despite their uselessness to her in particular, while naively believing the salesman in that the owner of the weapons would be blessed with happiness.[15] As a result, she had a debt of Beli98,000,000 and eight late fiancés.[10] Even when someone explains that she needs to stop granting favors to everyone she meets, she always ends up overwhelmed by the feeling of being needed. Her naïve nature was highlighted in her battle with Sai, as she mistook his words as flirtations and even offered to be of use to him, despite him being an enemy of her crew.

Outside of her desire to be needed, Baby 5 is an incredibly emotional person, once losing control and attacking Donquixote Doflamingo, her superior, for murdering her fiance.[1] She has repeatedly gotten angry at Law, only to cry and seek comfort from Buffalo moments later whenever he glares at her for scolding him.[16] In addition, despite her desire to be needed, she seems to be upset by people considering her as "convenient", as shown when she cried when Lao G called her such.

During her childhood, Baby 5 was something of a prankster, playing tricks on the ever-clumsy Corazon and getting a chuckle at the officer's expense, such as delivering scalding tea to him that burnt his tongue, despite being struck across the face in return.[17]

After Sai had married her, she was happy to finally become a wife as she happily clung to her husband's arm.[18]
