Seven of Nine would be an exciting character to include. Her unique backstory and abilities could add a lot to a crossover. In a crossover with the Doctor Who universe, for instance, her Borg knowledge might be useful in dealing with the Cybermen. Picard is also a classic character. His diplomatic skills could be put to the test in a crossover with the Star Wars universe, negotiating with the Galactic Republic or the Empire.
One idea could be a crossover with the Star Wars universe. Picture the Federation and the Jedi Order collaborating to face a common threat like a powerful dark force that can disrupt both galaxies. Another plot could involve a crossover with the Babylon 5 universe, where the political intrigue of both shows combines. The different species from Star Trek Online could interact with the unique races in Babylon 5, leading to cultural exchanges and power struggles.
A lesser - known but very interesting 'Star Trek 2009 Crossover Fanfiction' is 'Star Trek 2009 Meets Firefly'. This one is special because it combines the high - tech future of Star Trek with the scrappy, Western - influenced world of Firefly. The contrast between the two settings makes for a very unique reading experience, and the author does a great job of creating a story that respects both source materials.
In a crossover, the Borg from Star Trek could encounter Skynet. The Borg might see Skynet as a potential source of technology to assimilate. However, Skynet would likely resist assimilation and fight back. This could create a three - way conflict if the humans in the Star Trek universe also see Skynet as a threat and try to take advantage of the Borg - Skynet battle to destroy both.
The cultures in both universes are also ripe for exploration in the crossover. The Federation's values of equality and cooperation in Star Trek contrast with the more hierarchical and often morally ambiguous cultures in Star Wars. A story could focus on how characters from each side learn from or clash with the other's cultural norms.
I really like 'TNG and Stargate SG - 1: The Unexpected Encounter'. In this fanfiction, the crew of the Enterprise - D from Star Trek TNG stumbles upon the Stargate. It's a fascinating read as it explores how the two different technologies and cultures would interact. There are some really cool moments where Picard has to negotiate with the Goa'uld, and Data tries to understand the Ancient technology.
One great 'Star Trek DS9 Crossover Fanfiction' is 'DS9 and the Enterprise Crew'. It combines the unique characters from DS9 with the more well - known Enterprise crew in an exciting adventure. The author does a great job of keeping the personalities of all the characters intact while creating a new and engaging story.
One idea could be that the crew of the Enterprise discovers a distress signal from a Star Blazers ship. They then team up to fight a common enemy, like an alien race that is threatening both their galaxies. The different technologies and cultures would create an interesting dynamic.
Character development is another factor. Characters from both series can grow in new ways when exposed to the different rules and cultures of the other universe. For example, a Star Trek character might have to grapple with the concept of the Force, which could lead to a deeper understanding of their own beliefs and abilities.
One interesting idea could be the exchange of technology. For example, the Star Trek's transporter technology might be introduced into the Star Wars universe, changing the way characters travel between planets. Another could be a character crossover, like having Captain Kirk meet Darth Vader. It would be fascinating to see their different leadership styles and moral compasses clash or, perhaps, find common ground.
