Libitina Valdís

Libitina Valdís (Libitinaヴァル, Libitina Varu) is a member of the Stray Dog Pirates. It is unknown what her true intentions for joining Quade's crew are, but those closest to her (the few that remain) suspect that she simply enjoys killing. Her Devil Fruit, Desu Desu no Mi, grants her the ability to spawn multiple skeletal arms from her back, that she mostly uses for tearing her victims apart. This ability, along with her penchant for killing, contributed to her gaining the epithet "Hand of Death".

Personality
Libitina Valdís is a psychopath.

She doesn't have a conscience, none at all, no feelings of guilt or remorse no matter what she does. A deep seated rage is at her core. She has no limiting sense of concern for the well-being of strangers, friends, or even family members. Instead of friends, she has victims and accomplices who end up as victims. She is unable to empathize with the pain of her victims, having only contempt for others' feelings of distress and readily takes advantage of them. She often dominates and humiliates her victims. She doesn't struggle with shame, no matter what kind of selfish, lazy, harmful, or immoral action she has taken. She has ice water in her veins.

The concept of responsibility is unknown to her, except as a burden others seem to accept without question, like gullible fools. She has a grandiose sense of self, and feels entitled to certain things as "Her right", the end always justifies the means and she lets nothing stand in her way.

She does have the ability to conceal from other people that her psychological makeup is radically different from theirs. She has no problem lying coolly and easily, hiding the fact that she is conscience-free is nearly effortless. She appears to be charming, yet is covertly hostile and domineering, seeing her victim as merely an instrument to be used. When she shows what seems to be warmth, joy, love and compassion it is all an act and serves an ulterior motive. She is outraged by insignificant matters, yet remains unmoved and cold by what would upset a normal person.

When people do witness her cold-bloodedness first hand, they are horrified. Temporarily unable to accept that this unassuming beauty can be capable of such horrendous acts of violence. And by the time they can accept what they've seen, they're probably dead.
