Aaroniero Arruruerie

Aaroniero Arruruerie (アーロニーロ・アルルエリ, Āronīro Arurueri?) is an arrancar in Sōsuke Aizen's army, and the 9th Espada.

Character Outline
Aaroniero was a gillian, the weakest class of menos, before becoming an arrancar, and the last of the first-generation Espada. His original number wasn't mentioned, but it is possible he was demoted to a lower number in accordance to the arrival of more powerful Espada.

He usually covers his face with a white mask covered with six holes while in the light. In place of a normal head, he has a large, glass capsule filled with red liquid and two floating heads. The two heads are both tattooed with the number 9 and tend to talk in tandem when revealed, giving the effect of two people speaking in turn. The upper head speaks with a deep voice while the other speaks in a high-pitched, child-like voice, and appear to have a level of individuality. His outfit like most espada is customized; he wears a dress garb that covers his entire body as opposed to the normal jacket and hakama. He also wears a frilly nobles' coat that acts as his replacement jacket and two white gentleman's gloves.

History
While he was still a gillian-class menos, Aaroniero gained the powers of former shinigami Lieutenant Kaien Shiba by absorbing Metastacia, the hollow who killed and fused with Kaien. By doing this Aaroniero was able to gain not only Metastacia's power to fuse with others but Kaien Shiba's powers and abilities as well as his zanpakutō.

Arrancar Arc
Aaroniero is briefly seen as a shadow for some short periods of time in the Arrancar Arc, such as when Ulquiorra Schiffer reports to Aizen about what he and Yammy had encountered. He is seen the second time when Aizen is creating Wonderwice Margera. He is just seen standing there but this time only half of his body is covered in shadow.

Hueco Mundo Arc
He first appears when the Espada meet up, this time with his white mask on. He sits between Halibel and Yammy. He complains about the intruders along with Barragan, Szayel Aporro Granz and Nnoitra Jiruga. He is also heard talking for the first time and he has two voices one for each head. Aaroniero meets up with Rukia Kuchiki and tells her to follow him and as she does, he brings her into the dark room (his room), and takes off his mask just to show Rukia the face of Kaien Shiba. Rukia believes its actually him, so Aaroniero plays along with it. Rukia soon catches onto Aaroniero's trick and attacks him. The two do battle soon after Aaroniero shows his true face. He is defeated shortly after.

Abilities
Hollow Absorption: While all hollows can cannibalize each other to gain power, Aaroniero has the ability to completely absorb other hollows, merging not only their extra power with his own but also gaining their individual abilities. Once a hollow is absorbed in this fashion, Aaroniero can manifest any aspect of them at will, including their physical form. It is for this reason that Aaroniero, despite his gillian status, was able to become an Espada. Through an unusual series of events, he also absorbs the shinigami abilities of Kaien Shiba by eating Metastacia.

The weakness of this power is sunlight, which nullifies it on contact and reveals Aaroniero's true form.

Broadcasted Sight: Aaroniero also has the ability to broadcast information of whatever he is currently seeing or experiencing to other arrancar, which he does prior to his death at the hands of Rukia Kuchiki.



Nejibana (Twisted Flower):
 * Shikai: Its shikai command is "rankle the seas and the skies". Nejibana's shikai is represented as a cross between a trident and a ji (a Chinese halberd) with a crystalline appearance that has the ability to manipulate water. Like the ji, it bears a horsehair tassel, although it is blue instead of the traditional red; similarly the two side blades are straight with concave edges as opposed to the usual crescent blade. During Rukia's battle with Aaroniero, Nejibana's abilities are shown with the ability to use the shockwaves it creates in conjunction with trident attacks to "crush and split the enemy in two." Kaien's techniques and form are also revealed during the battle, and are described by Rukia as "a trident technique reminiscent of dancing."

Zanpakuto
Aaroniero's zanpakutō is. By chance Aaroniero's zanpakutō takes the form of former shinigami vice-captain Kaien Shiba's unreleased Nejibana. However his zanpakutō may also be a deformed arm-like appendage with many sprouting tentacles that is concealed in his left hand under his glove. It is activated by the command.


 * Manifest Absorbed Power: When sealed it allows Aaroniero to manifest any power he has absorbed through his zanpakutō, morphing it into a perfect approximation of the one he absorbed, as he does with Kaien's Nejibana.


 * Mimic Battle Style: His absorption ability also allows him to perfectly mimic the accompanying battle styles of those powers.


 * Total Manifestation: When released, it turns Aaroniero's lower body into a huge, blob-like mass resembling an incredibly bloated cartoonish octopus, with dozens of stubby tentacles and mouth-like mask pieces (In the anime the blob mass is colored purplish). When released it allows Aaroniero full access of his absorbed abilities. He can still manifest the powers of those he has absorbed in this form, but has no limit to the total number.

Trivia
His name like Grimmjow's and Nnoitra's was also a hot debate about his original name Arroniro being changed to Aaroniero; as well as his last name Arleri changed to Arruruerie.
