Plūtō ( ( ˈpluːtoː ) ; genitive Plūtōnis ) is the Latinized form of the Greek Plouton . Pluto 's Roman equivalent is Dis Pater , whose name is most often taken to mean `` Rich Father '' and is perhaps a direct translation of Plouton . Pluto was also identified with the obscure Roman Orcus , like Hades the name of both a god of the underworld and the underworld as a place . The borrowed Greek name Pluto is sometimes used for the ruler of the dead in Latin literature , leading some mythology handbooks to assert misleadingly that Pluto was the Roman counterpart of Hades . Pluto ( Pluton in French and German , Plutone in Italian ) becomes the most common name for the classical ruler of the underworld in subsequent Western literature and other art forms .
