Aizen's Arrancar army

The Hollows whose masks Aizen tore off with the Hōgyoku, turning them into Arrancar: an army led by Gin, Tōsen and the Espada, based in Las Noches.

The Arrancar are numbered: from 11 up the Números, from 100 up the Privaron Espada (demoted former Espada), from 1 to 10 the Espada. Each carries a Zanpakutō that seals their true Hollow form, unleashed with the Resurrección.
