Pluto

Greek and Roman A name used to refer to the god of the underworld. Pluto was a euphemism, a substitute name, for this much-feared god. In Greece, Pluto referred to Hades. In Rome, after Greek mythology came to strongly influence its religions, people used Pluto to refer to Dis or Orcus. People developed this alternative name to protect themselves from this dangerous god who was not easily influenced by the actions or offerings of humans. In Roman mythology, Pluto was the son of Saturn and brother to Jupiter, Juno, Neptune, and Vesta.
