This is a thread on the analogies between Sailor Moon characters and mythological gods (as well as implications)
Sailor Moon is Selene (Greek goddess of the moon, her lover is Endymion)
Sailor Venus is Aphrodite (goddess of love, her Latin counterpart was Venus)
Sailor Mars is Ares (so called because arrows used to be used in battle and fights, his Latin counterpart is Mars, hence martial arts)
Sailor Mercury is Hermes (her mother is a doctor in the same manner Hermes is the god of medicine and was said to have invented the lyre, his Latin counterpart is Mercury though Mercury is called Suisei or Water Star in Japanese astronomy)
Sailor Jupiter is Zeus (as in lightning bolts and love interests, his Latin counterpart is Jupiter)the t
Sailor Uranus is Uranus (the father of Cronos and the grandfather of Zeus, not much difference and her attack "World Shaking" may have something to do with Uranus forming the world)
Sailor Neptune is Poseidon (marine-based powers, her symbol is the trident which is associated with Poseidon, see King Neptune and Neptune)
Sailor Pluto is Hades (the realm she guards is the underworld, "Dead Scream" her primary attack has something to do with the dead and the shadowy underworld whom Hades is associated with, his other name is Pluto but appears more frequently in Roman myth and is sometimes associated with the native god of the underworld, Orcus)
Sailor Saturn is Cronos (that's the trickiest, "Death Reborn Revolution" may have something to do with the sickle, whom Cronos used to castrate Uranus, has symobilcally have something to do with death as well as with harvest, hence the Grim Reaper, his Latin counterpart is Saturnus)
I'm starting with Sailor Saturn. Saturnus or Saturn was the name of a god whom the Romans worshipped. Saturn was the abstraction of harvest and its destruction and that to the Greeks, his counterpart Cronos was a god of destruction and the sickle and harvest signified death. Go to Wikipedia and type Grim Reaper, you'll get the point.
