Hi all, feel free to use, ignore, fold spindle or mitilate 
these fict concepts any way you find useful.

Ranma:
1 A Ranma Mortal Combat X-over:  First off play a little fast and loose 
with MK2 and 3, so that Shao-Kahn gets beaten on Outworld, and 
Sheng-Sung is killed in the process.  Everyone thinks that's that, but 
Sheng Sung was Very into survival, so he had a contingency plan ready. 
 When his body was killed an old spell of his triggered, and his sould 
was drawn into a special magic figurine he had prepaired and hidden on 
earth.  With his soul inside it the figurine started the next spell, a 
summons to a person who would be willing to use the power he offered 
and thus become the means of his reserection.   And into the ship where 
the figurine was for sale walked Hikaru Gosenkugi.

2 Genma Must Die:  Actually an idea that makes that a genuine 
condition.  Basically some event occures, and Genma reacts strangely to 
it.  His insensitivity and arogance are ampliflied, and he also 
developes a sadistic streak and becomes much cleverer.  It's after the 
new Genma trashes Happosei that the truth is revealed.  Genma is 
actually a fake personality and body created by a powerful demon that 
needed to hide it's presence on the world.  In fact Genma was designed 
to be kind, careing, and very honerable, but having a demon for your 
soul has it's effects.  However now the demon is lose and it's got big 
plans that would not be good for anyone, especially Ranma.

A few Non-Anime ideas:
WOD-VTM and X-files: My dinner with Malachov.  Mulder is constaltly 
searching for the truth, now he gets the chance to learn it in the form 
of a meeting with one of the few beings who actually has all the 
answers.

WOD-VTM and B5.  Just the basic Babalon 5 storyline with the addition 
of two new characters, Two Rival Antidiluvians, one living on B5, the 
other living on earth.
