First, know both universes well. For a Stargate Atlantis crossover, you need to understand the technology, characters, and settings of Stargate Atlantis as well as the other universe you're crossing it with. Then, come up with a unique concept. Maybe it's a situation where the Atlantis team has to team up with characters from another show to defeat a common enemy. Keep the characters in - character. If you're writing a crossover with, say, Star Wars, make sure the Atlantis characters act as they would in their own show while interacting with the Star Wars characters.
When writing a Stargate Atlantis crossover fanfiction, start with a strong plot. Think about how the two universes will collide. Will it be a scientific accident that brings them together? Or a deliberate action by an enemy? Also, focus on the character relationships. If you're crossing over with Doctor Who, how will the Atlantis team react to the Doctor's time - traveling and eccentric ways? And don't forget to have fun with it. Let your creativity run wild while still staying true to the source materials.
To write a Stargate Atlantis crossover fanfiction, you should do research. If you're crossing over with a comic - book universe, for example, learn about the different characters, their powers, and their backstories. Next, plan your story structure. Decide how the story will start, what the middle will be like, and how it will end. In the middle part, build up the interactions between the Stargate Atlantis characters and the characters from the other universe. You can have them exchange knowledge, have cultural clashes, or even fall in love. Just make sure it all flows together and makes sense within the context of the two universes.
