Stargate • 1647 stories • Updated 19 Dec

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.
