|Headquarters||Las Noches, Hueco Mundo|
|Affiliation||Sōsuke Aizen's Arrancar Army|
|Purpose||Combat experts of Sōsuke Aizen's Arrancar Army|
The moment they are "reborn" from Hollows into Arrancar, each member of Aizen's army is assigned a two-digit number, starting with 11. This number indicates not the order of the Números' strength, but of their birth. Thus, the higher an Arrancar's number, the younger they are. The strongest among the Números can be handpicked by Aizen and promoted to Espada.
Fracción (従属官 (フラシオン), Furashion; Spanish for "Fraction", Japanese for "Subordinate Officers") are Arrancar that serve a specific Espada. As proof of their status, the Espada have the right to select subordinates from among the Números to supervise directly. They can choose one or many Fracción, or even none at all.
List of Números
- In the English language release of the anime and manga, Fracción is pluralized as Fracciónes.
