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.
One key difference is the overall tone. Star Wars fanfiction often focuses on the battle between good and evil in a more 'epic' sense, with the Force playing a central role. In Star Trek fanfiction, there's more exploration of different cultures and moral dilemmas. Another difference is the technology. Star Trek has a more utopian view of technology, while Star Wars technology is often more about raw power and combat. Also, the characters in Star Wars fanfiction tend to be more archetypal heroes and villains, compared to the more complex and diverse characters in Star Trek fanfiction.
It's really hard to say which has more popular fanfiction. Both have huge and dedicated fanbases. Star Wars has the advantage of being more mainstream in recent years with the new movies. However, Star Trek has a long - standing and very loyal following. It might depend on the platform you look at. Some sites might have more Star Wars fanfiction due to the hype around the new releases, while others that are more focused on science - fiction in general might have a more balanced amount of both.
There are fanfictions that explore the concept of a crossover in a more humorous way. In some, Chewbacca and Worf end up in a series of comical misadventures together. They might misunderstand each other's cultures and languages at first, but then gradually form an unlikely friendship as they work towards a common goal, like saving a planet that is important to both Star Wars and Star Trek universes.
One popular theme is the exploration of alternate universes. In Star Wars fanfiction, it could be a universe where the Empire won. For Star Trek, it might be a universe where the Federation has different relationships with other species. Another theme is character crossovers, like having a Star Wars Jedi interact with a Star Trek Vulcan. And of course, there are often romances between characters from the two universes, which fans find really interesting.
One popular theme is the exploration of alternate universes. For example, a story might show what would happen if the Federation from Star Trek and the Galactic Republic from Star Wars had to form an alliance. Another theme is character crossovers, like having Captain Kirk meet Luke Skywalker. And relationships between characters from the two universes are also explored, such as a friendship or a rivalry between a Starfleet officer and a Jedi.
I think Star Wars novels are better. The Star Wars universe is filled with so many iconic characters like Luke Skywalker, Darth Vader, and Princess Leia. The novels expand on their stories in ways that the movies can't always do. There's also the allure of the dark side and the light side of the Force, which adds a layer of mysticism. Star Trek novels are good too, but they lack that kind of mythic, larger - than - life quality that Star Wars has.
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.
In Star Wars fanfiction, Han Solo is often featured. His roguish charm and his relationships with other characters like Chewbacca and Leia are interesting to explore. In Star Trek, Captain Picard is a popular character. His diplomatic approach and his moral compass make him a great character for fan - created stories. Also, Seven of Nine from Star Trek: Voyager is a popular choice because of her unique backstory and her journey of reintegrating into society.
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.
