What epithet meaning 'receiver of many' was used for Hades?

The epithet meaning “receiver of many” was used for Hades, and the stored answer is Polydegmon.

Polydegmon comes from the Greek Πολυδέγμων and is commonly rendered as “host of many” or “receiver of many.” The title suits Hades because his underworld realm receives the dead. Greeks also used indirect or euphemistic titles for him because speaking the name of the god of the dead could seem ominous.

Hades had several other epithets. Plouton, meaning “the wealthy one,” connected him with the riches hidden beneath the earth, including fertile soil and metals. Clymenus is another title, while Eubuleus may refer to “good counsel.” These alternatives are related names or epithets, but they do not match the wording in this question as closely as Polydegmon.

Hades was the ruler of the underworld, not the personification of death itself. That role belonged more specifically to Thanatos. In later Roman tradition, Hades was closely identified with Pluto.
