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 common theme is the exploration of different timelines. Since Star Trek has multiple timelines, crossovers often play with how the Enterprise crew would interact with those from other timelines. Another theme is the sharing of technology. For example, how the tech from the Enterprise could be combined or compared with that of other Trek entities in the crossover.
The novelty of it. Combining Star Trek 2009 with other universes gives a fresh take on the well - known Star Trek world. For example, if it's crossed over with a superhero universe, we get to see how the Star Trek characters react to superpowers and vice versa.
A popular 'Star Trek Lower Decks Crossover Fanfiction' is the one that crosses over with 'Star Trek: Voyager'. In this fanfic, the Lower Decks characters end up on Voyager. It's a fun read as they bring their unique Lower Decks humor and chaos to Voyager's already complex situation of being stranded in the Delta Quadrant.
Archive of Our Own (AO3) is a great place to find 'Star Trek Lower Decks Crossover Fanfiction'. It has a wide variety of stories written by different fans, and the tagging system makes it easy to search for specific crossovers.
First, know your source materials well. For a 'Star Trek TNG' crossover, you need to be familiar with the characters, their personalities, and the technology in 'Star Trek TNG'.
