Números

The are a subsection of the Números that directly serve a specific Espada. The number of Fracción for any given Espada varies: Stark and Nnoitra Jiruga would seem to have just one, while Szayel Aporro Granz has at least a dozen. There are a few Espada that apparently prefer to fight alone, such as Yammy, Ulquiorra Schiffer, Zommari, and Aaroniero, and chose not to have any Fracción under their command.

Fracción Relationships
Stark's relationship with Lilinette is something of mix between Captain Kenpachi Zaraki and Lieutenant Yachiru Kusajishi's of the Eleventh Division, Captain Shunsui Kyōraku and Lieutenant Nanao Ise's of the Eighth Division, and Shinji Hirako and Hiyori Sarugaki's. She acts more like a younger sibling than a servant, though Stark doesn't seem to mind.

Halibel's Fracción respect her and take everything she says seriously, as they should given an Espada's immense amount of power. They may even be somewhat intimidated by her given their facial reactions when she told them that it's 'understandable to be afraid' of an Espada's Resurrección form. They themselves appear to have a strained, yet somewhat comical, relationship with one another.

Barragan's Fracción are fiercely loyal to him and even consider him as their 'god'. Much like Barragan himself, they are all arrogant and somewhat foolhardy compared to the other Fraccion.

Nnoitra's lone Fracción, Tesla, idolizes him and treats him as a sort of 'king'.

Grimmjow's Fracción are loyal and obediant but disregard their comrade, D-Roy, calling him the weakest of Grimmjow's Five Fracción, and reluctantly accepting his 'assistance' during Grimmjow's Assault on Karakura. Edorad Leones scornfully calls him 'an arrancar in name only'.

Szayel's Fracción are more like cloned drones than henchmen and he shows little to no concern over them, even going so far as to cannibalize them in order to replenish his strength and regenerate his wounds, as seen during his fight with Renji Abarai and Uryu Ishida.
