In some fanfiction, a great concept is the clash of Khan's dictatorial nature with the democratic ideals of the Star Trek Federation. It could lead to a lot of internal conflict within a ship or a station when he tries to impose his will, and the crew has to figure out how to deal with him without violating their own principles.
Another concept might be the idea of Khan teaming up with certain Star Trek characters. Maybe he forms an unlikely alliance with Spock, where they both use their logical minds to solve a major problem that neither could solve alone. Khan could bring his brute force and determination, while Spock offers his Vulcan wisdom and knowledge of Starfleet protocols.
One interesting concept is the mixing of different Star Trek series' characters. For example, seeing characters from The Original Series interact with those from Deep Space Nine. It creates unique dynamics as their different cultures and values collide. Another concept could be the introduction of new species that are a combination of species from different Star Trek universes. This can lead to all kinds of new storylines about how these new species fit into the existing galactic politics and relationships.
One interesting concept could be the interaction between the Federation in Star Trek and the Galactic Republic in Star Wars. For example, how would their different forms of government and ideologies clash or cooperate? Another concept might be the use of technology. Star Trek has the transporter and Star Wars has the hyperdrive. How would characters from each universe react to the other's technology? Also, the idea of Jedi and Vulcans interacting due to their shared emphasis on mental discipline is really cool.
One interesting concept could be the sharing of jutsu in the Star Trek universe. For example, how would a Vulcan react to seeing Naruto's shadow clone jutsu? It could be a fascinating exploration of different cultures and powers colliding.
One interesting concept could be the meeting of different species from both universes. For example, seeing how a Wookiee from Star Wars would interact with a Vulcan from Star Trek: Voyager. Another might be the exchange of technology. The lightsabers of Star Wars and the phasers or replicator technology from Star Trek could lead to some really cool scenarios. Also, the moral and ethical differences between the two franchises could create some intense storylines when the characters collide.
One interesting concept could be the clash of different ideologies. In Warhammer 40k, there is a lot of grimdark and a strict hierarchy, while Star Trek is more about exploration and unity. So seeing how characters from both universes react to the other's values can be really engaging.
One interesting concept could be alternate timelines. Fanfiction often explores how different events in the Star Trek 2009 universe might lead to completely new storylines. For example, a different outcome of a battle could change the power dynamics among different species. Another concept is character development. Writers might delve deeper into the backstories of characters, like exploring Kirk's early days at the Academy in more detail than the movie did.
Spock is also a common character. His logical nature contrasts with Khan's more passionate and sometimes reckless behavior. Writers like to explore how Spock would handle Khan's unpredictability and whether he could reason with him.
Fanfiction about Khan in 'Star Trek Into Darkness' can be really interesting. It often explores his character in more depth than the movie might have. Some fanfics might focus on his backstory, like his time as a genetically engineered superhuman before being frozen. Others could explore his relationships with the crew of the Enterprise in alternate scenarios.
Well, for one, his physical and mental prowess is really captivating. In fanfiction, this can be exploited in unique ways. Also, his conflict with the Enterprise crew offers a lot of room for creativity. Writers can rewrite their encounters, give Khan new strategies or goals, and in doing so, create a whole new 'Star Trek' adventure centered around him.
One interesting concept is alternate timelines. Fanfiction often explores what would happen if certain events in Star Trek Generations occurred differently. For example, if Picard had made a different choice during his encounter with Soran. Another concept could be the expansion of character backstories. Maybe delving deeper into the history of Data or Worf in a way that wasn't fully explored in the movie. Also, the idea of crossovers within the Star Trek universe is common. Such as characters from other Star Trek series interacting with the events and characters of Star Trek Generations.
