The angel, or demon Abaddon has appeared many times in works of literature, films, television and popular culture. In Hebrew the term Abaddon (Hebrew: אֲבַדּוֹן Avaddon), means "doom"; the Greek equivalent is Apollyon. In the Christian Bible it is both a place of destruction and an angel of the abyss. In the Hebrew Bible (Tanakh), abaddon is a bottomless pit, and often appears alongside the place שְׁאוֹל (Sheol), meaning the realm of the dead.
