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.
A common theme is the struggle between duty and motherhood. The pregnant character may have important tasks on the Enterprise, but her pregnancy makes her question her priorities.
Exploration of new worlds and concepts is also a big theme. If 'Star Trek' crosses over with a different sci - fi series, they might jointly explore a new and strange planet or phenomenon. This allows for a lot of creativity in terms of what they discover and how they deal with it. It can be something as simple as a new form of energy or a complex new alien race.
Isolation can also be a theme. There could be a situation where Reed is separated from the rest of the crew, either physically or emotionally. This can lead to a lot of self - reflection and character development as he tries to survive and reconnect. This theme can create a lot of angst and interesting storylines in fanfiction.
A lot of fanfiction also focuses on their roles on the Enterprise. Hoshi's language skills and T'Pol's scientific and logical thinking are often put to use in various missions. For example, in some stories, they are the key to solving a mystery on an alien planet. Hoshi can communicate with the aliens, and T'Pol can analyze the scientific data related to the situation. This theme of teamwork and how their individual skills complement each other is quite popular.
There could be exciting possibilities like combining the advanced tech of Star Trek with Doctor Who's time-travel adventures. But the challenge could be keeping the tones and characters of both shows consistent.
One common theme is the exploration of different cultures. When Star Trek crosses over with other universes, there's a chance to compare and contrast the unique cultures from each. For example, if it crosses with a fantasy universe, the highly technological and logical Star Trek culture might be contrasted with a more magic - based and traditional culture.
One popular theme is Malcolm's relationships with the other crew members. This could be his friendship with Trip, and how they support each other during difficult missions. Another theme is Malcolm's backstory. Many fanfictions explore his past, like his training and what led him to join Starfleet.
One common theme is the clash of cultures. Star Wars has a more mystical and feudal - like society in some ways, while Star Trek is more about a united federation. When they cross over, exploring how these different cultures interact is a big theme.
There's also 'Enterprise's New Allies'. In this fanfiction, the Enterprise crew crosses paths with a group from a different Trek timeline. The story delves deep into how their different technologies and cultures blend. It's a great read if you like exploring the potential of crossovers within the Star Trek universe. It has some really interesting plot twists and character developments.
The theme of unity against a common threat is also quite prevalent. In many crossovers, whether it's with 'Firefly' or other science - fiction universes, the characters from DS9 and the other universe have to come together to face a powerful enemy. This often leads to the characters learning from each other, growing, and forming unexpected alliances. It's about how different beings can put aside their differences when survival is at stake.
