Tier Harribel

Halibel is an arrancar in Sōsuke Aizen's army, and one of the top three most powerful Espada. She is the only current female Espada.

Character outline
She has dark skin, green eyes, spiky blonde hair with several braided locks, and wears an oddly-cut variation of the arrancar jacket that bares a good portion of her breasts. The jacket is extended slightly in the anime to better cover this. Halibel carries her zanpakutō on her back; the sword itself is notably broad and short compared to others and has a western-style guard. The remnants of her hollow mask are partially covered by her collar, but it is clear that she at least has pieces of mask on both sides of her cheeks. Halibel rarely speaks, and when she does is fairly serious, such as when she tells her subordinates that being afraid of an Espada's released form is a natural reaction. She stated the battle between Ichigo Kurosaki and Grimmjow Jeagerjaques was more like an fight between two espada than anything else.

Plot Overview
She first appears during Aizen's meeting about Ichigo Kurosaki, Yasutora Sado and Uryu Ishida entering Hueco Mundo to save Orihime Inoue. Currently Halibel and her three Fracción are in battle with the Gotei 13.

Fracción
Halibel's Fracción consists of three female arrancar:

is a tomboy-ish arrancar with mismatching eye colors, one blue and one orange; the latter eye has a red ring around it. Apache's mask fragment is on the top of her head with a horn in the middle much like that of a unicorn. Apache has not been shown to carry a zanpakutō.

is a dark-skinned arrancar who dresses like an Amazon warrior. Her mask fragments form a three-sectioned crown around her head and a thick necklace. Her hollow hole is positioned midway between her navel and breasts. She has been shown to be holding some kind of wrapped stick, but it is unclear if it is her zanpakutō.

dresses somewhat like Luppi, with sleeves that extend well past her hands. She also has two belts criss-crossing each other on her waist. Sun-Sun has long, flowing green hair and three dots below her right eye. Her mask remnants create three hair clip-like extensions on the right side of her hair. Her hollow hole isn't visible. She seems to be the most mature of Halibel's Fracción, advising Apache and Mila Rose to stop arguing, as it makes them look weak, then chiding their angry responses.
