Sugar

Sugar is a special member of the Donquixote Pirates' Trébol Army.

Appearance
Sugar appears to be a young girl, but is actually much older. This halt in aging is due to the effects of her Devil Fruit.

In the anime, she has light blue hair, a pink monocle with a purple covering, and a white dress with blue polka dots.

Personality
Not much is known about her personality, but since she helped Doflamingo take over the kingdom of Dressrosa, and turned many citizens into toys, despite knowing that anybody who knew them would forget them, she can be assumed to be a person with evil motives.

Much like her namesake, Sugar apparently enjoys eating sweets. She has also been shown to appear innocent, as shown when she ran around the palace, looking for Doflamingo, after he had already left for Punk Hazard.

Donquixote Doflamingo
Being her captain, it can be assumed that Sugar has a good relationship with Doflamingo. She seems to follow his orders, since she keeps the toys of Dressrosa transformed.

Trébol
Sugar seems to have a good relationship with Trébol, since he is her bodyguard.

Abilities and Powers
Sugar has not been shown fighting, and it can be assumed that she is weak, since Trébol has been assigned as her bodyguard, implying that she needs him to protect her from harm.

Devil Fruit
Sugar has the power of the Hobi Hobi no Mi, which allows her to turn people into toys, as well as erasing the memories of those who once knew them, as well as their own of others who have been turned into toys. She used this ability in order to help Doflamingo take over Dressrosa.

Past
Sugar was seen ten years ago, assisting the other Donquixote Pirates in the invasion of the palace. After Doflamingo successfully took over Dressrosa, Sugar turned many of the citizens into living toys.

Punk Hazard Arc
Sugar was first seen sitting beside Doflamingo, on one of his chairs outside the Dressrosa palace. She watched and ate candy as Baby 5 attempted to attack Doflamingo, and as Doflamingo talked to Vergo about the situation with Law.

She was later seen searching for Doflamingo. She asked Lao G and Jora where Doflamingo had gone, to which Lao G responded by telling her that he was probably in the room on the fourth floor. Sugar then told him that Doflamingo was not in the room, to which Lao G sighed, and replied by saying that Doflamingo had gone out by himself again.

Dressrosa Arc
She is currently the target of the Riku Royal Army's attack against Doflamingo.
