OT: What I hope is a new kind of Challenge

[Mad-Hamlet@xxxxxxx]

Greetings,
Yup, still hammering at Forge.. Promise.
I was just taking a break though and filtering some older fanfics. 
I've noticed a plethora of 'Buffy Gets Vamped' fics. 
Usually this end up with her becoming some sort of incredibly powerful 
monster as the author cites the combination of vampiric strength with 
Slayer powers. 
More often than not these wind up as kill fests. Which is fine.
But this lead me to thinking, and being the incredibly dangerous thing 
that is, my thought led me to thus:

Given that 'A Slayer' is a force for Light, and it is eveninced by 
such things as Slayer Strength, Slayer Speed, Stamina and, of course, 
Slayer Wit is can be easilly surmised that there is an outside Element 
added to the Mortal shell to cause these changes. A Catalyst so to 
speak. 

Add that too..

A Vampire is a force for Dark. And this is also shown with Vampric 
Speed, Strength, Dentures etc..ad infinitum. Once again we have an 
outside force, another Catalyst that is added to the mortal frame to 
cause these changes. Often refered too(Somehwhat carelessly IMHO) as 
'The Demon'. 

So, we have to Outside Catalysts that alter a mortal physioligy, and 
most likely their mental and spirtual one as well. (Slayers:A little 
more..alive. Buffy is many things but disspassionate is not one of 
them. Vamps: Much colder, no sense of morals. Children basically.)
These two catalyts are diametrically opposed to each other, so what 
would happen if both these agents of Power find themselves locked into 
one mortal coil?

Do they combat? Causing the poor person to be driven mad as one Aspect 
gains an upper hand for a brief moment before the other side wrestles 
control away?

Do they annhilate each other? The image of an unopposable force 
striking an immovable object comes to mind.(whatever that looks like.) 
causing said Mortal coil to be reduced to a mere mortal or even spread 
out all over the road?

Or is something new made? Something Grey. With all, none, more, 
less..something never seen before and what exactly would that be?

This is not an easy thing to concieve of. Maybe I'll look into it 
myself but I'm busy. I'm hoping someone snaps it up.

What does this have to do with Shippyness? Having an emotional anchor 
could make, or break this..combined entity..saving all..or destroying.
Something like this could easilly go either way. This is not easy 
though, real looking into the Powers behind the Catalysts and maybe 
the disturbing realization that Light and Dark are not so diffrent 
after all.

And no, under no circumstanes is anyone allowed to use the line "The 
needs of the one outweigh the needs of the many." Brrrrr..

I remain, as always,
Mad-Hamlet
