One reason this fanfiction is appealing is the potential for unique storylines. Combining the two universes allows for a vast array of possibilities. Maybe a Mass Effect character gets stranded in the Star Trek universe and has to adapt to a different set of rules and technologies.
One common theme is exploration. Both Star Trek and Mass Effect have a strong focus on exploring the unknown, and in fanfiction, this often leads to exciting new adventures. Another is the idea of different species interacting. For example, seeing how Vulcans from Star Trek might interact with Turians from Mass Effect.
One common theme is the exploration of different cultures. Both Star Trek and Mass Effect have richly diverse cultures, and in fanfiction, it's often explored how they would interact with each other.
One common theme is the exploration of different species and cultures. Since both Mass Effect and Star Trek have a rich variety of alien species, fanfiction often delves deeper into their interactions. Another theme is the concept of technology and how it affects the characters and their universes.
One interesting Mass Effect and Star Trek fanfiction could be about a crossover where the crew of the Enterprise encounters the Reapers. Maybe they team up to fight a common threat that endangers both their universes. Another could be a story that focuses on a character from Mass Effect who somehow gets transported to the Star Trek universe and has to adapt to their technology and values.
Fanfiction in this area can also focus on character interactions. Picture Commander Shepard meeting Captain Picard. Their leadership styles are different but both are very effective. A story could be built around them having to work together to face a common threat, perhaps a new alien race that is more powerful than any they've faced before. It would be fascinating to see how they strategize and combine their skills.
One popular crossover is where the technology from Star Trek is incorporated into the Mass Effect universe. For example, the warp drive from Star Trek might be used to enhance the FTL travel in Mass Effect. Another common one is having characters from both universes meet. Maybe Captain Kirk could encounter Commander Shepard. It's interesting to see how they would interact given their different leadership styles and moral compasses.
One interesting plot could be the combination of Mass Effect's biotics with Star Trek's technology. Imagine a character from Mass Effect using their biotic powers to interface with Star Trek's advanced computer systems in a unique way. Another plot could involve the different species from both universes coming together to face a common threat, like a powerful new enemy that neither could defeat alone. And perhaps a story where a Star Trek ship ends up in the Mass Effect galaxy and has to navigate the complex politics there while also trying to find a way back home.

Well, in some Star Trek vs Mass Effect fanfiction, there are often epic battles. Imagine the Borg from Star Trek facing off against the Reapers from Mass Effect.

Also, the Starfleet officers' principles and ethics could clash or blend with the Spectres' more flexible code of conduct in Mass Effect.
