I'm also looking for stories that have a member of the Senshi turned into a monster of the negaverse, negamoon, nega-whatever....
Thanks alot.

Hmmm... well... recently on FanFiction.NET I remember coming across one that had Makoto born from Ranma and a Youma, making her 1/2 youma. Can't remember te name though.
For other stories centering on youma and monsters, I suggest possibly:
SM 'Waking Ami' by PinaPoe - [Status=Complete] - [Last Dld=01/28/2005]
SM 'Love and Lament' by PinaPoe - [Status=Not Complete] - [Last Dld=09/25/2006]
And also:
R-SM 'Youma 12' by James Thomas - [Status=Complete] - [Last Dld=03/01/2005]
I also remember a couple where Ranma becomes in charge of some youma. One was an AA adventure, the others I'd have to recheck. The Anime Addventure one was:
R-AA 'Setsuna's Fault-Dark Lord Ranma' by Multiple - [Status=Not Complete] - [Last Dld=07/14/2007]
And it's sequel:
R-AA 'Dark Lord Ranma' by Multiple - [Status=Not Complete] - [Last Dld=03/27/2008]
