Roman tradition. See the whole pantheon.

Ruler of the dead. Dis Pater ('wealthy father') was the Roman name before Pluto, a Latinised Greek name, entered use.
Greek counterpart: Hades on thegreekgods.org. Roman and Greek versions share names and stories in many places but began as different cults.
Deities in other traditions who share a theme with Pluto / Dis Pater: death and the underworld, earth, harvest and fertility. This is overlap in one area only.
