This is something that I've been doing alot of, that is, introducting new
characters into various fanfics, most notably, Megumi Shirow, who is
featuered in a good number of my Ranma fanfics.

        Is there any guidline on new characters or what?

Let's see... from what I know...

SAOTOME, RYO
series: Descents and Inversions
info: son of Ranma Saotome and Ukyo Kounji.  Looks extremely like Ranma.

SAOTOME, RANKO
series: Careful Destiny
info: in an alternate universe, Ranma Saotome's sister.  Looks like
      Ranma-chan, except with black hair.  Trained in Anything Goes.

HIBIKI, IYANAKO
series: Give Peace A Chance
info: younger sister of Ryouga Hibiki.  Brutally strong, wields a parasol.

MUHOSHIN, RYO
series: The More Things Change
info:  a psychotic Gosunkugi lookalike with a mean streak and surprising
       martial arts ability.

HIBIKI, RATIKO
series:  Ranma 2096
info:  the alleged great grandson of Ryouga Hibiki and Ukyo Kounji.  Is
       every bit like his great-grandfather.  Jusenkyo cursed to be a
       female fruitbat.

SHURIKEN
series:  The Shuriken Cycle
info:  practitioner of 'mystical creature' martial arts.  Comes to Nerima
       to fight a mysterious dark force and get help.

Others:  there was a fic with three Saotome Daughters in it....
I just can't remember their names! =(  it was from "December's End"
I think... heck, there's loads more characters, but I'm just naming
these off the top of my head.  ANybody else got stuff to add?
