        I would appreciate any ideas and suggestions about this. Thanks for
listening.

It'd be only interesting if it was a non-martial artist.  
Gos, Akari, Nabiki, or even Nodoka comes to mine.
You can have Ranma and crew coming to the rescue, but that
takes time.  Time that the hunters hunts his prey.

What the prey has going for them:

Gos - The natural ability to become not noticed.
      Example:  Hunter: Dammit!  Where is that little bugger?  
                        I can't even find him with my 
                        Infrared/Night Vision Binocular?

                Gos: <Please don't turn around, oh please don't
                      turn around!>

Akari - Knowledge of animals (pigs in particular)
        maybe the flora and fuana as well in terms of what pigs
        should, could, can't, wouldn't eat.
        Example:  Hunter:  Ewww!  What's that smell...
                           Oh bloody damn! That's the third
                           pile I stepped in.  Well, no way
                           a delicate, pretty girl like her
                           can be here...

                  Akari:  <Hmm... this feces(sp?) should hide my
                          smell from the hounds and the boars
                          here seem to trust me around them. 
                          They tend to move around a lot so I 
                          should be safe for a while.  Oh Ryoga, 
                          I hope you get here soon...>

Nabiki - Natural ability to avoid trouble.  And has a knack for
         coming up with nasty surprises and setup.
         Example:  Hunter:  Oww!  Damn that girl!  Get off me you
                            little monster.  Oww!  That hurt!
                            Stop that! Oww!...

                   Nabiki:  How do you like those monkeys?
                            <Hmm... Giving those chimps a stick
                            with a sharp end seems to be a good 
                            idea.  Now lets see if I can persuade
                            those jackals to chase him around a
                            bit.  Damn wish I had my camera.
                            Ranma better get here or I'm going to
                            raise his interest again.>

Nodoka - Always carry that sword around.  Who knows, may actually
         know how to use it.
         Example:  Hunter: Wooah!  What the heck!  This isn't one
                           of my traps!  <Where's that bloody 
                           knife...> [The hunter seems to be 
                           hanging upside down, held in mid air
                           by freshly cut vines that were braided 
                           for added strength.]
 
                   Nodoka: I'll admit, carrying off girls is manly.
                           But you must understand I'm married.
                           Do you get my point? [Nodoka shoves the
                           sword at the hunter's face, stopping
                           within an centimeter of contact.]

                   Hunter: Uhh...
