In one of my stories, I've examined the idea of Willow Rosenberg picking up one of the Blackened Denarii (from the Dresden Files; basically allows a Fallen Angel to rent out space in the 90% of your brain you don't use, making you one bad sorcerer). That's kind of an obvious mix, but what would happen if Dawn Summers (the sweet, kind, overly gentle Dawn) were to become a Denarian?
Would she become uber-evil (they say the greatest cruelty comes from the greatest caring, after all) or would she have the strength of will to remain untainted by the Fallen?
Well, you tell me!

Crossover with Lynsay Sands Argeneau Novels

Some vampires escape Buffy’s world to a dimension without a slayer. There they start causing all kinds of problems. The Atlantian Council thinks that one of their people have gone rogue. A vampire/Atlantian of your choosing is dispatched to resolve the issue and destroy the rogue Atlantian/vampires.

Meanwhile the Powers That Be send Buffy (or another Buffy character though I am hoping for Buffy) to destroy all of the Hell Mouth Vampires. The vampire/Atlantian you decide on stumbles upon her just as she dusts a “real” va...

New Moon - After the Cullens have left.

While Bella is still immersed in her depression she meets Connor Stephen O'Halloran, a boy who becomes his friend and help her find a small measure of peace. Then, right when she believes her life will finally be normal she discovers such a things is impossible, for Connor is the 'Destroyer', a half-vampire demon-hunter known and feared in several worlds, and also her younger brother...

Buffy is Bella's biological mother, gave birth to her the summer after she sent Angel to hell; Angel is obviously the father. Buffy named her daughter...

Buffy/Dresden Files

The Wardens of the White Council somehow become aware of Willow and of some/all of the violations of the Laws of Magic she has committed. They then begin a hunt to apprehend her and bring her in for a trial which if she is found guilty would result in her beheading. The Scooby gang will of course try to defend Willow from the Wardens.

It's up to you if Harry Dresden appears in the story. You could use another Warden if you want.

I would recommend setting this at least after season 6 of Buffy and at least after Dead Beat for the Dresden universe if...

A crossover with Perry Rhodan:
A simple question: What would Buffy's life be like if she lives in the universe of Perry Rhodan?

After "The Gift" Buffy lands in the world (and age) of Conan the Barbarian and perhaps meets Conan himself, but she need to become his lover. It would be fun if she met the slayer of that age and falls in love with her, but it is not required.
No m/m slash please.

Twilight Xover

Set during New Moon

Bella is activated as a Slayer when Willow does the spell. Moving to Sunnydale to help fight the First she makes friends with Dawn and Spike.

I don't recall ever seeing a crossover between Buffy and Ender's Game, so I decided to issue a challenge. Here are the parameters:

1) Must be set during the Ender series timeframe, not the Buffy timeframe.
2) Must include at least two Buffy/Angel characters.
3) Must not be dimension/reality hopping.
4) May include other crossings so long as Ender and Buffy/Angel are the primary ones.

I've seen a couple Xander as a Dragon Rider... and who doesn't love a good Xander gets a power up fic? Heck, they're some of my favorites. But, that's not what this challenge is. This is a Buffy as a Dragon Rider Challenge.

Now, before I even finish the challenge, let me say I'm already writing my own version, and I don't know when I'll post it, but I like to see what other people can do to. Now on to the rest of the challenge.

Must start in Sunnydale, but it can end up in Alagaesia. (In fact, I'd prefer it span both worlds, but that's to your discretion, it doesn't have to.)...

"Arriving at each new city, the traveler finds again a past of his that he did not know he had: the foreignness of what you no longer are or no longer possess lies in wait for you in foreign, unpossessed places. [He] enters a city, he sees someone in a square living a life or an instant that could be his; he could now be in that man's place, if he had stopped in time. long ago;or if, long ago, at a crossroads, instead of taking one road he had taken the opposite one, and after long wandering he had come to be in the place of that man in the square. By now. from that real or hypothetical past o...

Being a reader and not a writter (was told not to quit my day job), I offer as challenge, yet another Halloween story, but of the Vor nature.

I would like to see a story where one (or more) of the Scoobies get's taken over by one of the Vor (See Bujold - ie: Vorkosigan, etc...)

But you'd really make my day, if Xander got taken over by the "Runt" .. yes, the one and only Miles Naismith Vorkosigan ..

I offer this challenge humbly.

BTVS/Dune

"It was a time of sorceresses whose powers were real. The measure of them is seen in the fact that they never boasted how they grasped the firebrand." from Appendix II The religion of Dune by Frank Herbert.

Dune is still my favourite sci-fi novel I'd like to see more fics in this universe so here are a few plot bunnies.

1) Paul Atreides lies dead. Killed in his duel with Feyd-Rautha Harkonnen, at the moment of what should have been his greatest victory. As he foresaw the Fremen use his ghost as their banner, they launch their jihad on an unsuspecting univer...

BTVS/Ubik

Because there should be more fics crossing Buffy with books by Philip K. Dick.

Buffy is dead. As the Scoobies start to mourn her after the events of the gift the world starts to warp around them. They start seeing Buffy's name and image everywhere: on commercials, billboards, in magazines, they even see her face on dollar bills. As their world starts to fall apart, as they get pick off one by one they learn something is helping them and something is trying to destroy them. They start to receive bizarre, bewildering messages purporting to be from Buffy. The stranges...

Crossover with Stephenie Meyer's newest novel "The Host"



When Wanda, Ian and the others are stopped by what they think are Souls, they're shocked when they turn out to be a group of even more humans who managed to evade the Seekers, as well as another Soul gone good.

What will they think when they stumble upon another group of survivors led by a pissed off blonde Vampire Slayer whose hell bent on taking back the world she's saved too many times to count?

Who is in her group is up to you. Have the Scoobs teamed up to save the world once again? Or has Buffy j...

Very simple it can even be a oneshot if you want.

Xander dresses as the greatest of all reaper men Death from the Disc for Halloween.

Simple enough strange enough, however when it ends Xander gets a visit from the original to tell him that the death of his world (Buffyverse) has used him as an excuse to retire.

Xander must now act as death in true discworld fashion.

I would also love to see several crossovers in this. Several supernatural shows, Charmed, Supernatural etc as well as Anime...Hellsing is a must. and any others you can think off.

His p...
