List of Arrancar

Below is the list of known arrancar based mostly on the numbers given to them in Aizen's army.

Espada
The Espada (Spanish: sword) are the top-ranked arrancar in Aizen's army. The Espada at the time of the group's introduction consists of nine males and one female. Each Espada member is chosen for their superior combat ability and then assigned a number from 1 to 10 that indicates their rank and relative power level, which is tattooed somewhere on their body. The Espada are given control over the Números and are regarded as the strongest arrancar in existence. Similar to the power gap between captains and lieutenants in the Gotei 13, the strength of the Espada far surpasses that of the average Número.

Top 3 (exact ranks unknown): Halibel, Stark, Barragan

5th: Nnoitra Jiruga (Deceased)

6th: Grimmjow Jeagerjaques

7th: Zommari Leroux (Deceased)

Former Espada

 * Neliel Tu Oderschvank - Formerly the 3rd
 * Luppi - Temporary 6th (Deceased)

Privaron Espada
The Privaron (Spanish: deprived) are former Espada who have officially lost their rank and are assigned a three-digit number. Being former Espada, they are far stronger than the normal Números. They reside in Tres Cifras, which translates literally from Spanish as "three digits". As mentioned by Dordonii, these former "naturally created" Espada were rendered obsolete after Aizen began artificially creating arrancar to meet his own standards.


 * Dordonii Alessandro Del Socacchio - The 103rd (Deceased)
 * Cirucci Thunderwitch - The 105th (Deceased)
 * Gantenbainne Mosqueda - The 107th

Números
The Números (Spanish: numbers) are the combat specialists. They are assigned a two digit number at birth from 11 to 99 to indicate their age (Número 11 is the oldest, Número 99 is the youngest). The basic Número uniform consists of a white-collared jacket and robes held with a black sash. However, the uniform is customizable, giving each Número a sense of individuality. The fighting ability of Números is thought to be superior to all other arrancar, except for the Espada (current and former).
