OK. Hear are some fanfic ideals for you to concider:

1) Ranma VS Street Fighter 2/3: The Reawaking Of Vega.
     After Vega's (M.Bison's) defeat from Ryu, Vega was attacked by one of his
own 'special projects', Gill, and left for dead. Now, Gill has taken over
Shadoloo, and wants to conqure the earth. Ryouga finds Vega, and, not knowing
who he is, nurses him back to health at the Tendo Dojo. Finaly, Gill learns of
Vega's continued exsistance. Ranma has to face the wrath of Gill. Akane gets
kidnaped (Oh no, not again) (or somebody else, if you can figer out how to get
Ranma to resque the person). And who is this mysterous person who is watching
all of this, and chuckling to himself? Oh, ya, Ryu cameo in begining, and
end(?).

2) The Ultimate Fight.
     Ranma gets defeted by the mysterous martial artest called Akuma Taou, who
is supose to be the son of Pantyhose Taou and that girl who fell in SOD
Demon. But he is 16 years old, same as Pantyhose. What is going on hear? Ranma
trys to train anew, and also gather together 6 other strong martial artest
(basicly, swallowing his pride and amiting 'I can not defeat this basterd
alone'). The others are: Ryouga Hibiki (of corse), Terry Boagard, Ryu (from SF
fame), a mysterous girl named Uma (who seems to know vareants of Ranma's own
attacks, and wears a bracelet similer to Akuma Taou), a mysterous kid with a
monkey tail flying on a cloud and wilding an extending staff, and a blind man
who is 140 years old who Ryu knows and calls himself Oro (or, whoever you see
fit, as I am only giving ideals away). After a long training session, and
battal with Akuma Taou, thay win (but at what cost?).

3) Ranma VS Inn-Yashie (forgive my mispellings).
     Yep, Ranma, the old Tak-hime faverot, VS Inn-kun, the new Tak-hine
faverot. Who will win?

Stan.
