What if Willow's spell didn't just activate the slayers on this planet? When the goa'uld took their slaves to seed the galaxy, were humans all they took? Could Andrew enter the SGC without hypervenilating to death? The answers lie within our selection of Stargate crossover fanfics.

Join the Scoobies as they go through the Stargate with Jack, Sam, Daniel & Teal'c, or head further afield to the city of Atlantis.

Not long after "Chosen" the Buffyverse reality is destroyed due to the instability in the balance when all the Potential Slayers were activated. The PTB barely manage to open a portal and send Buffy to the Stargate reality before everything is obliviated.

Must have:
- Buffy as the only survivor from the Buffyverse, and she brought the Scythe with her.
- Buffy has become immortal due to a combination of her being the Slayer, her resurrections, and because Willow used Buffy as her focus for the Slayer Activation Spell.
- She arrives in Pegasus at some point in the past and ...

After shooting Linsey McDonald in 'Not Fade Away' a depressed Lorne makes a wish to be sent somewhere far away, where he'd be out of reach of the Senior Partners, and where he'd always be able to get a Sea Breeze. But capitalization doesn't come over in a verbal wish and he finds himself taking the place of Major Evan Lorne when the Daedalus delivers reinforcements to Atlantis at the end of 'The Siege Part 3'. How will the gentle empath cope when he finds he's expected to fight space vampires? Do his sonic powers work against the Wraith? How will the people of the Pegasus Galaxy react to s...

Unable to get the last toy gun at Ethan's Xander instead buys a set of armor like medieval suit of armor except this one came with a staff, some strange snake shaped thing that at a flip of a switch it stood up like a snake.

And of course there was that strange helmet that was also shaped like a snake along with the strange gold symbol Xander had to put on his forehead.

What if instead of just buying a toy gun from Ethan's Xander also bought a set of Air Force special forces fatigues.

In this universe Stargate Command has gone one step further in their cover story. Rather than Wormhole Extreme they have actually allowed Stargate: SG-1 to be filmed and shown figuring where better to hide the truth than behind itself. That being said, someone(in or out of the group) has convinced Willow, Xander, and Buffy to go as the three human members of SG-1. The catch? Willow, as a confidence booster, talked the others into each going as the character that they resembled least. So, Willow is Jack, Xander = Sam, and Buffy gets to play Daniel. Let the craziness begin.

I'd prefer ...

In season 4, the way the Initiative operated led to the creation of Adam and their own destruction.

What if they had been under different management?

What if Maggie Walsh had never been involved?

What would the Initiative have been like if it had been run by Colonel Jack O'Neill and Dr. Samantha Carter?

Rules:
- This is a Point of Divergence challenge. Everything should be the same as canon up to the point where the co-commanders of the Initiative are chosen, and then the changes should butterfly from there.
- Additional SG-1 characters may be includ...
