Her name isn’t really Darcy, of course: her true name is something much older and a damn lot more powerful. Norse gods weren't the only supernatural beings in New Mexico when Thor was there.

After the final Seal is broken, Dean discovers that he's actually Lucifer. He's not really sure how he feels about that.

Gabriel has a way out, if he can just get the gods on his side.

“My high school reunion is on,” John tells Molly. There’s a short pause as she processes this. “That sounds like fun,” she offers. “Do you want to go?” “Oh yes, because that couldn’t possibly go badly. ‘Hello, I’m John Watson, I’m a professional killer.’ ” A Grosse Pointe Blank AU.

Sherlock has just run off in a whirlwind of coat without a word, leaving Scotland Yard cursing his name. It’ll be a while before they can get someone to translate this, and meanwhile that tall know-it-all bastard has gone off to do god-knows-what without bothering to even tell them what the note says. John edges forward in the middle of the uproar, and surreptitiously glances at the note. Androvy, it says briefly. The warehouse at five. Serdyukov. John seems like such an ordinary bloke. Appearances can be deceptive.

One rainy afternoon Tony gets home to find a wet-haired child in an over-sized bathrobe sitting on the penthouse couch, watching cartoons. “Um, what,” says Tony. “Oh, hey,” Harley says, noticing him. “JARVIS showed me where to go. He told me to leave my clothes in the bathroom so they could dry, and said I could borrow one of your bathrobes. You have a really big TV, you know that?”

In which Darcy Lewis is actually Hel Lokisdottir, Queen of Helheim, and Phil Coulson is the badass secret agent we all know and love.

Apparently Supernatural was real, which was presumably why Gabriel was bleeding out onto Richard’s floor. (In which the actors of Supernatural find that reality is stranger and more disturbing than they previously believed, even counting Misha, and an injured archangel discovers that his universe is the subject of a TV show.)

“You’re Captain America!” I said, because he was. “Uh, hulloooo, standing right here,” Tony told me. He was using his obnoxious voice. “I know you’re there,” I said. “But Captain America! You didn’t tell me Captain America was going to be here!” A sequel to 'A Connection Is a Thing Which Requires Maintenance.'

The thing that made it so easy to hide was that everyone knew what dragons were supposed to be like. John heard people wonder about Sherlock sometimes, sending him slanting, speculative glances, as they questioned his lineage. But John Watson, who was steady, reliable, even-tempered? He slid right under their radar, just another average human being in a world full of them.

“Eternity is really rather boring, John. Mortal life seemed as though it would be far more interesting.” Sherlock is actually the Devil, but he decided to live as a mortal because ruling Hell was boring.

Years later, Tony meets Harley Keener at a science and engineering fair.

Discovering that you have some kind of angel-marriage, soulbond-thing to your nerdy angel friend kind of forces you to re-evaluate your relationship. In Dean's case, this involves freaking out and massive fail.

What it says on the tin. (Including Follow-ups to: Maybe one of these days you can let the light in, and One Of Those Things, and Mrs and Mr Pond..)

What if Castiel had taken a different vessel?

The first thing Tony says when they come down to breakfast the morning after moving into the Tower is, “So, you two are together, right?”

“I don’t understand why everyone is so obsessed with sex!” Loki burst out. "There are far more interesting things."

Tony used to think that the 1940s were repressed. Steve's repertoire of racy songs makes him reconsider.

Clint is an omega who isn't interested in mating. Ever. That doesn't mean he wouldn't like a romantic partner, though. Unfortunately, he's never found anyone who was okay with the whole lack of interest thing... but there might be hope yet.

In which Dean turns out to be the archangel Michael (surprise!) and decides that they're doing this Apocalypse thing his way (i.e. not at all), the rest of Team Free Will (plus Gabriel) help out, and the Host, the demons, and various other characters are along for the ride (eg. fellow archangels, grumpy hunters, hapless prophets, etc). Alternate universe.

Loki is Thor's sister, not his brother. The events of Thor go somewhat differently.

Sometimes Darcy thinks life would be much easier if her grandfather weren't a homicidal terrorist with metal-bending powers.

“Your first mistake,” John says smoothly, “was calling yourself Moriarty. It got my attention.” In which Jim is not, in fact, Moriarty.

Looking at the contemplative expression on Lucifer's face, Sam thinks that this has the potential to be either very bad, or completely awesome. Two humans and two archangels in the Cage.

"Sorry, you have me confused with the other angel. You know, the one in the dirty trench coat who's in love with you." Dean and Castiel finally have that conversation.

And how things could have gone differently.

Sam smiles, bright and luminous. "An angel's Grace isn't just power, Dean. It's a part of their soul." An AU 'verse that takes place after episode 5.22.

Two hundred years ago the Winchesters stopped the apocalypse. Now, instead of getting into fights and running amok, eighteen year old Jim Kirk goes to live with his Auntie Sam and learns the family business. Four years later, an angel shows up.

Mutants have been extinct since the Eugenics War. But then, Jim's the exception to everything.

When Loki attempts to mind-control Tony Stark in the middle of the Chitauri invasion, he unlocks powerful memories and abilities, and Tony realises that he's something greater and more powerful than he ever knew. And so is Steve Rogers, but that's a slightly different problem.

Loki falls from the Bifrost, and lands in Lilo's garden. Chaos ensues.
