Hollow (Bleach)

Hollows are a fictional race of malignant ghosts in the anime and manga series Bleach created by Tite Kubo. They are corrupt spirits with supernatural powers that devour the souls of deceased humans. Hollows are the principal antagonists during the first part of the manga and remain a primary threat throughout most of the series. Hollows settle in the Hueco Mundo (Spanish, lit. hollow world; grammatically, the phrase would be Mundo Hueco, meaning 'a world that is hollow'), but can cross over to the human world and Soul Society.

Tite Kubo has used a Spanish motif for hollows and arrancar throughout the series. The kanji used by him to write hollow is 虚, which means "emptiness" (or 虚ろ, utsuro — hollow). However, it is pronounced hollow (ホロウ horō?) instead of using its native pronunciation.
