When Joyce and Hank take a road trip with their one year old daughter, Buffy, they happen upon a recently downed spacecraft. A recently downed spacecraft containing a baby Kal-El, and take him in, calling him Clark.

Clark Summers grows up an apparently normal boy, but when the Summers family moves to Sunnydale, it slowly becomes apparent that he's anything but normal. Then again, in a family that has a Slayer for an eldest child and a ball of rift opening and dimensioning destroying green energy for a youngest child, an alien with superpowers for a middle child isn't really that far o...

Ethan ran out of guns that Halloween. So Xander was stuck with some weird screwdriver thing and a borrowed suit. He didn't remember much of that night. He didn't remember why everyone was more than a little scared of him. And he had absolutely no idea why he had two hearts and a constant drum beat in his head.

And, most puzzlingly of all, why did he respond like someone was saying his name every time someone used the word 'Master'?

A song based challenge, from the song 'Behind Blue Eyes' by the Who. Post Avengers Loki and pre soul Spike meet and exchange a few thoughts, god and vampire finding that they aren't so different after all.

Spike's amulet finds it's way to Torchwood Three just after Kiss Kiss Bang Bang (or during, for comedic value). Chaos ensues.

The NWC does not trust Torchwood. Torchwood doesn't really trust anyone, but want to get rid of the snarky vampire.

Pairings as canon, with Spike pining after Buffy.

When Warren shot Tara, and Osiris refused to resurrect her, a cosmic entity took notice of Willow's grief. A cosmic entity with a certain fondness for human redheaded women. The Phoenix has found a new host. God help planet earth.

After the final battle, Harry Potter gets caught in a magical accident involving a time turner, and wakes up in the 1970's with a new face. Despair causes him to turn to a certain Ethan Rayne, and go down some dark paths in hope of a return to his natural time. In the end, taking the slow path, he becomes a Watcher. And after Sunnydale is destroyed, his life as Rupert Giles is turned on it's head when a certain Ginny Weasley is a newly activated Slayer.

Non slash for Harry, possible Ginny/Xander or Ginny/Willow. Pairings and plot are open.

Tony Stark had a little sister, one who objected to the family business and distanced herself from her family. Post Loki's attack and his third near death experience in the last couple of years, he decides to look her up on the grounds that family's important and he's out of the weapons business. And reacts badly when he finds out that his eldest niece is a supernatural warrior on a short life expectancy, and naturally decides to help out. Whether she wants him to or not. Naturally the rest of the Avengers catch wind of this and follow him. Steve is angry with the Watchers. Bruce is curious ab...

In Harry's fifth year, Hogwarts decides to start their students corresponding with muggles to understand more of the muggle world. Harry ends up with Buffy Summers, Freshman student at Sunnydale High for a pen pal. Neither knows the truth about the other. Both are blissfully ignorant of the other's Chosen One status. Like that's going to last. Any pairing, Harry/Buffy friendship (possible romance).

Willow is a witch with great power, the greatest in her world, who must fight against the darkness within her. Esmerelda Weatherwax has been doing just that all her life. Giles sends Willow to learn control from the best.

Post Series 6, Pre Series 7. For Discworld, recommended post Carpe Jugulum, but any time could work.

(Preferably) YAHF. If YAHF :What if Xander decided to go in Crusader gear? Crusader gear with a very particular sword, Amoracchius. How will the power balance of the Buffyverse be affected by the appearance of one of the swords of the cross, let alone the other two when they (inevitably) turn up?

Or: After the Buffy Season 1 finale and (Dresdenverse) 'Small Favour', Harry Dresden finds that Amoracchius has discovered a new bearer.

Preferably longer than a one shot.
