Kalifa

Kalifa was Iceburg's secertary and is the only female of CP9 group.

Personality
When we first see Kalifa in chapter 323 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.

But in chapter 341, she shows her true colors by aiding the attack on Galley-La HQ while disguised in a cloak and mask. In Water 7, she uses a spiked whip for attacking, climbing tall buildings and for restraining Franky for arrest. In chapter 345 she was revealed as a member of the secret Government agency known as Cipher Pol No. 9, or simply "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.

However after eating the Devil Fruit and facing Nami in chapter 410 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.
