The Vizard masked army (kamen no gunzei), pronounced in English as Visoreds (vaizādo), is a group of Shinigami that have acquired Hollow powers. Following the battle at the Fake Karakura Town, they have become central combatants against Sōsuke Aizen's Espada.

The Vizard are the antithesis to the Arrancar as Shinigami who have obtained Hollow powers.

Having begun as Shinigami, the Vizard appear entirely Human and bar those times where they are using their powers are indistinguishable from ordinary Shinigami. To gain access to their Hollow powers, a Vizard dons a Hollow mask. This allows them to augment their Shinigami abilities with Hollow powers, as well as giving them access to some of the more generic Hollow abilities. Their spiritual pressure likewise changes into a mix of Hollow and Shinigami. This process of donning one's Hollow mask is referred to as Hollowfication.

Vizard have been shown to be former captain and lieutenant Shinigami. They are considered criminals by the Soul Society for committing the ultimate taboo of acquiring Hollow powers; their status as former leaders of Soul Society also marks them as traitors.

During their introduction, they are viewed as reclusive and are thought to be only having loyalty to themselves, for it was unknown what role they would take in the upcoming battle at the fake Karakura Town. However, they are still considered to be valuable allies in the war against Sōsuke Aizen's army of Arrancar, according to Kisuke Urahara. The Vizard haven't shown any sort of hierarchy, preferring a loose-knit organization.
