Kalifa

Kalifa was Iceburg's secretary and is the only female belonging to CP9.

Galley-La
When we first see Kalifa as Iceburg's secretary, she seemed to be a serious, businesslike woman with a hot temper. She does not like being referred to by her name, considering it sexual harassment. She is, at first, fiercely loyal to Iceburg and is always seen walking around with him.

CP9
During the Enies Lobby arc, Kalifa personality becomes sly and crafty, as she enjoys embarassing her superior, Spandam by accusing him of harassing her. She also seems to fit the dumb blonde stereotype during her fight with Nami.

Devil Fruit
Kalifa's fruit is Awa Awa no Mi (アワアワの実 Bubble Bubble Fruit.

However after eating the Devil Fruit and facing Nami, Kalifa was reduced to taking things lightly and was proved that she is not as bright as she was (such as mistaking Monster Chopper for Nami). It was this unfocused and impulsive attitude that led to her defeat at Nami's hands.

Weapons
In Water 7, she uses a spiked whip for attacking, climbing tall buildings and for restraining Franky for arrest.
