Pluto is a dwarf demon from Hades. He was first mentioned in Golem in the Gears.
Pluto is the widower of Persephone, husband of Eve, ex-lover of Sharon, and father of Plato.
Pluto was demoted to Dwarf Demon in a Demon bet. In a fit of rage, he broke the Cable between the Mundane Internet and the Xanthian Outernet and does not want it fixed because of a bet with Demon Eris. He falls in love with and marries Eve. His name is stylized as P|L/U|TO.

Human men and women will not have a species in their entries. Also, if the surname of the character is the character's species, it was dropped.
If the character is a child, it will be in the description. The child will more than likely be an adult by this time in the Xanth series.
Many species are single gender, so their entries will not mention it. The species are Fury, Muse, basilisk, cenmaid, cenmare, cockatrice, dryad, maenad, sand witch, sandman, and woodwife. Harpies and nymphs are usually female, and fauns are usually male; but there have been a few exceptions that are noted.
In some instances, I have made educated guesses on gender, species, and some birth years.
