The Vizards are a group/race of fomer Shinigami who acquired Hollow powers.
While the term Vizard is spelled in the manga using kanji meaning masked army (仮面の軍勢, kamen no gunzei), it is pronounced as the English visored (ヴァイザード, vaizādo).
The Vizards are the antithesis to the Arrancar, Shinigami who have obtained Hollow powers. Having begun as Shinigami, the Vizards appear entirely human, and barring 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 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 "Hollowification".[
