It's got zombies in it but they're not the main villain by any means, other than that I don't think I know of any. Hope this helps!

Try this one: Take Heart by Dutchbuffy2305 Buffy and Spike form a reluctant team to take clean up the post-Initiative mess. Magic, sex, snarks, sparks, romance, horror and farce ensue. Did I mention sex?

The best zombie fic I've ever read is To Ride A Pale Horse by Athenewolfe and Weyrwolfen. The fic is Spuffy, but revolves around the zombie outbreak post Btvs. It is absolutely brilliant and I've never seen another fic that compares to it. Not only is the writing some of the most superb I've ever read, but the imagination behind this fic...well, nothing can compare to it. There are several original characters in this fic that they have created with complete personalities that suck you into the plot even deeper and make you love them, or hate them as much as we all love the cast of Btvs and foremost Spuffy.

Sadly it is a WIP and has not been updated in a very long time, although as of the last time I spoke with both authors they do intend to finish it when they have time. The fic has 16 chapters and more than 48,000 words, plus two short fics that go with it. It can be found on the Just Rewards archive under the author Athenewolfe, or on the Elysian Fields archive under author name WeyrAtheneWolfen. At Elysian Fields the main fic plus the two small ficlets are the only fics under this name so it is real easy to get all of the story so far.

I'm the one who posted about the fic To Ride A Pale Horse by the two authors who combined their names into WeyrAtheneWolfen. I just realized I didn't add their summary for you.

To Ride a Pale Horse
by Athenewolfe and WeyrWolfen

Summary:
I see no man on a pale horse, yet Death rides for us all.

It was the apocalypse no one saw coming. Now, longtime enemies must become allies, friends become foes, and death really is waiting around every corner. A tale of death, sacrifice, more death, the human (and not so human) heart, even more death, black humor, and the end of the world as we know it.

These sound amazing! Thank you everyone!
