Well, there could be a plot where a Mass Effect character is somehow beamed onto a Star Trek ship. This could lead to all sorts of misunderstandings and adventures. The Mass Effect character might be initially distrustful of the Star Trek crew's more peaceful ways, while the Star Trek crew could be shocked by the Mass Effect character's combat - oriented skills and the use of biotics. Then, they could gradually learn from each other and work together to solve a mystery that spans both universes, like a strange energy signal that is causing disruptions in both galaxies.
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.
A great plot might be the exploration of how the different forms of space travel in both universes interact. In Mass Effect, there are the Mass Relays, while Star Trek has warp drive. A fanfiction could explore what would happen if a Star Trek ship tried to use a Mass Relay or vice versa. Also, the cultural exchange between the two universes could be fascinating. For example, how would the more militaristic elements of Mass Effect react to Star Trek's Prime Directive? Or how would the utopian ideals of Star Trek be received in the often harsher Mass Effect universe?
