Another theme is power and its use. In Naruto, there are powerful ninjutsu and kekkei genkai. In Star Trek, there are advanced weapons and technologies. Fanfiction may explore how these different forms of power interact when the two universes collide. For example, could Naruto's Rasengan be enhanced by Star Trek technology? Or could a Star Trek phaser be modified with ninja knowledge? It's all about the combination of the two power systems.
The theme of friendship and alliance also frequently appears. Characters from Naruto and Star Trek have to learn to trust and work together. They might start off as strangers or even enemies due to their differences. But as they face common threats, like a powerful villain or a dangerous phenomenon that affects both universes, they form bonds of friendship and alliance. This theme is often used to show how different beings can come together for a greater good.
His struggle with the ethical dilemmas of medical practice in space is also a common theme. Since he has to deal with different alien physiologies, he often faces tough decisions. In some fanfictions, this is shown through his internal monologues as he tries to figure out the best course of action.
A frequent theme is the exploration of different cultures. Since Star Trek is all about encountering diverse alien species, in 'Star Trek and Reader' fanfiction, the reader gets to experience and interact with these cultures. Also, there's the theme of self - discovery. The reader character may grow and learn about themselves while being part of the Star Trek universe, facing challenges and making choices that shape who they become.
Conflict, both internal and external, is also a frequent theme. It could be conflict between different species, or internal struggles within the crew. For example, moral dilemmas are often explored, like whether to interfere with the development of a primitive civilization or not. And of course, the theme of friendship and teamwork is also prevalent. The characters on the Andromeda rely on each other to overcome challenges.
One common theme is McCoy's friendship with Kirk and Spock. Many fanfictions explore how their relationships develop further in different scenarios. Another theme is McCoy's medical skills and how he uses them in challenging situations. For example, dealing with new alien diseases or treating injured crew members during dangerous missions.
Love and romance can be a theme too. Maybe a relationship with another crew member or someone from a different planet he meets during his travels. Additionally, there are themes related to his Russian heritage, like how it influences his thinking and actions on the ship.
One common theme is the clash of cultures. NSYNC comes from a very different cultural background (90s pop music scene) compared to the Star Trek universe. So, fanfictions often explore how they interact with the more science - fiction - oriented and often more serious Star Trek characters.
One common theme is forbidden love. Given the diverse species and different cultures in the Star Trek universe, relationships that are not allowed or frowned upon are often explored. For example, a relationship between a Federation officer and a Romulan.
One common theme is redemption. Since Khan has a rather complex past in the Star Trek universe, many fanfictions explore whether he can be redeemed for his actions. Another theme is power. Khan is a powerful character, and stories often deal with how he wields or is tempted by power.
Another theme is the clash of cultures. The militaristic and often post - apocalyptic setting of Halo is very different from the more utopian ideals in Star Trek. Fanfiction often explores how characters from both universes deal with these differences. For example, in some stories, the Halo characters might be shocked by the Star Trek's Federation's peaceful approach to resolving conflicts. And the Star Trek characters could be in awe or horrified by the more violent nature of the Halo universe at times. It makes for really interesting character dynamics and plot developments.
Power and control is also a frequent theme. Vampires in these fanfictions may seek power within the Star Trek universe, either by influencing key figures or taking over starships. This theme plays on the idea of the vampires' natural thirst for dominance and how it intersects with the power structures already in place in the Star Trek universe. This can lead to complex power struggles and moral dilemmas for the characters.
