Interesting take!

great story development hope to read more

Not bad.

Some form of Succubus, omg. The Slayers and Watchers wouldn't like that comparison!

That's a very interesting perspective on slayers. Alas, but that's all I really have to say: it's a really freaking cool idea that I never would've thought of.

Interesting point of view on the Slayers. Now I keep wondering how the Watchers Council might interpret the Grimms.

Interesting...

Buffy and Faith?

This was very well done. Dare I hope you have plans to write a longer story about this?

This is 3,000% exactly the Grimm/BtVS crossover I was hoping to see. You're brilliant! Thank you for this fantastic crossover!

I actually really don't like the idea of Slayers being Wesen and having another "face." It devalues the whole show as then what about Glorificus? Was she just a really powerful Wesen who was delusional about where she came from? What about magic and dimensional rifts? Because you gave them another "face" you placed them in the Wesen category meaning that it is the Buffy universe that would be all wrong about what they are fighting.
Despite all of this, I do commend your efforts at attempting to bridge the two serious.

This looks very promising. Slayers as a form of Wesen. That is an intriguing idea.

Love to see more of this its an intresting work

Nick hasent bee hunting as long but hes a cop and he uses his head oh yeah and uses a FUCKING GUN!
so he could kick some ass

be intesting to see the horo fo the slayer girls when they realize they have been killing regular people
well regular sort of people

if Nick can see them like he can se the others it might mean they are the same type of creature

could explain that real well and hell vampires are the same way

magical genetic experiments higher powers making foot soldiers

but some of these would be stronger than a slayer, I have never seen a slayer take someones arm of eith their bare hands so it would be intresting as long as the worlds were blended right

but slayers as wesen? be awesome man
thanks for this

Love it! great idea. Need more Grimm/Buffy blending!

OMG LOVE. LOVE LOVE LOVE.

I've kinda wondered at the Grimm/Slayer connection. Seeing things as they truly are is kinda psychic, right? And while Nick is nowhere as strong as a Slayer, he HAS done thing a normal human couldn't. (Also, the wicked fighting skills against the reapers? Awesome).

I totally squeed when you called them Sineyans.
