Somehow or another, some alien race goes back in time and annexes Earth in the Buffyverse time. They are merciful with the human population, but they use them as 'bounty-hunters' for rounding up HST 'free labor' (i.e. slave-labor). (Should be a secret takeover, could be alien internal politics involved; such as competition between the 15th and 10th Cardassian Orders- the 10th being the Military Intelligence Division.)
Could be the Cardassians, Romulans, Klingons, Ferengi, Orion Syndicate, whatnot... but should be something that uses a high degree of criminal labor in it's economy. The only...

Remember the TOS episode "Mirror, Mirror" and the Mirrorverse in general? Evil Spock with a beard and the Terran Empire (Roman-esque)? Well, you're going to put Xander in some sort of Star Trek Mirrorverse - and it is *not* going to be due to Halloween, a Wish, Q, or the PTB (this includes intermediaries like Whistler: let's not be cliché here). If you want him to have grown up through the Eugenics Wars and WW-III and be sent to the future for some reason, great, that works. If you want him a bit shocked by the true evil in *humanity*, go for it (though a difficult one to pull off). Want to m...

Years before the Eugenics Wars, before the augmented humans took control and ruled over humanity, they lived and worked under the governments who created them. The life of one particular famed augment goes slightly off course when a young Khan Noonien Singh is out on a mission of some sort. He happens upon a demon attack, and the young, beautiful girl showing great skill in the field saves his life unexpectedly.

This girl is an equally young, more Wish!verse-like Buffy Summers, having lived her whole life under the Council's control. She's rougher around the edges, but the old Buffy i...

From the original Starfleet charter, the organisation was born. No, not Starfleet although, yes, but Section 31, named after the part of the charter that enables their existence in a 'peacekeeping through peace' force.

But who wrote that charter... that part?

The Challenge: One, two or more of the scoobs who survive long enough, and with plenty of life left to live, heads the new Slayers/Watchers Council, only it's in a vastly different form than before... and returning to the ways of the secret... basically a scoob is the head of it, and created it. alone or as a group, is u...

Slayers, Buffy in particular, were the model for creating super humans. Perhaps Buffy was briefly captured and her DNA stolen, or the creators themselves managed to mix magic and science to create them. However the writer wants to explain it is fine, but what I really want is for Khan and his crew to see her as a mother.

Before their centuries-long sleep, Buffy was believed to be killed in battle, possibly protecting them. But what no one knew is that she was actually captured and studied before being placed in a frozen sleep of her own, far from her "children."

When Khan aw...

Spoilers for Star Trek: Into Darkness

After her jump into the portal, Buffy wakes up in another universe. With a body like her own, only far younger, but somehow better, stronger, genetically modified to be a weapon. In short, she is one of Khan's crew, his family. They're all just children now, though she retains some memories of who she was before.

Her presence in his life makes Khan, and in turn the rest of the crew, more sympathetic to humanity and not as brutal. They were slowly becoming better people, not just the "weapons" they'd been created as. Buffy and Khan grew to...

Halloween 1997.
Xander's costume idea falls through, again.
Instead he finds a Vulcan outfit. Any of the Star Trek series or time frames are applicable. Except this Vulcan is not a named character from the series. No Spock.
He is, however, young.

Some time after the Halloween episode, he starts to feel sick.

Very sick.

The challenge is that one of the female characters, Buffy, Willow, Cordelia, or just someone entirely surprising, but in the same age bracket, recognizes this as the early stages of the Vulcan Pon farr, knows what needs to be done, but is ...

OK basic premise Principal Schneider is a closet Sci-Fi geek especially for anything and everything Star Trek and he orders all of the "volunteer" escorts on Halloween to dress as characters from any one of the Trek shows or movies.

Schneider himself dressing as Quark

Giles, Miss Calendar, and Mrs. Summers also in trek costumes (Giles as Worf with Jenny as Jadzia Dax would be particularly interesting)

minimum bashing and then only of those truly deserving of it such as Spike, Warren, and other similar characters

Buffy must remain the Slaye...

Write a story where the Buffy characters wind up in an occupied Bajor or Terok Nor. What season of Buffy it takes place in, how they got there and what happens is entirely up to you. You can even decide whether they look like Bajorans, Cardassians, or themselves. Whether it's one shot or has multiple chapters is up to you. Characters can interact how they want but make sure to keep them in character.

Willow says that Vamp!Willow is "kinda gay". Intendant Kira clearly is bisexual. Both evil versions have designs on their good selves.

I'd love to see someone write a fic where Vamp!Willow survives to the Star Trek DS9 era and becomes involved with Intendant Kira, and then somehow there's a crossover from (or to) the "normal" universe. Any four of the characters can be crossed, but all four must be present in the story. Length is irrelevant, but I love long stories, so the longer the better.

Let's see what's out there...

Buffy the Vampire Slayer/Star Trek 2009 crossover

Starts in Halloween

{You can decides pairings for other main characters. : ) }

It is Halloween and Xander just missed getting a plastic gun. After asking with Ethan Xander some how gets a box filled with odd miss matched items that go with Star Trek 2009 for $5 not that he or Ethan know what they are.

It includes Scotty's red shirt and black undershirt, Uhura...
