One interesting aspect might be the character interactions. Picture Captain Kirk trying to charm the ponies or Spock having deep philosophical discussions with Twilight Sparkle about the nature of existence. The different cultures in Star Trek, such as the Klingon warrior culture, could also contrast with the peaceful pony society. This could lead to some really unique storylines where the ponies have to deal with more aggressive or complex beings, and the Star Trek characters have to adapt to the more harmonious and magical environment of Equestria.
One interesting idea could be the technology exchange. For example, the Star Trek's warp drive might be compared or even combined with the Star Wars' hyperdrive in some creative ways. Another could be the meeting of characters. Imagine Captain Kirk facing off against Darth Vader. It would be a clash of two very different leadership styles and moral compasses.
One idea could be that the crew of the Enterprise discovers a distress signal from a Star Blazers ship. They then team up to fight a common enemy, like an alien race that is threatening both their galaxies. The different technologies and cultures would create an interesting dynamic.
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.
Well, in some fanfiction, there are crossovers that involve character swaps. For example, Captain Kirk finding himself in the Star Wars universe and having to navigate the politics and power struggles there. He might use his charm and quick - thinking from the Trek universe to make an impact. Another concept could be the Jedi and Vulcans sharing their knowledge of the Force and logic respectively. The Jedi could learn about strict emotional control from the Vulcans, while the Vulcans might be intrigued by the concept of the Force.
One interesting idea is the combination of Star Wars' Force with Star Trek's technology. Imagine Jedi using their Force abilities to interact with Star Trek's advanced consoles or warp drives. Another is the meeting of iconic characters like Luke Skywalker and Captain Kirk. They could learn from each other's leadership styles and approaches to conflict. Also, the different species from both universes coming together, such as Wookies and Vulcans, and how they'd interact culturally.
One interesting idea could be the interaction between the different alien species from both universes. For example, seeing how Vulcans from Star Trek would interact with the Minbari from Babylon 5. Maybe they would exchange knowledge on logic and philosophy.
One idea could be that Buffy and her team are transported to the Star Trek universe. Maybe they have to fight vampires that have been affected by some sort of alien technology. Another could be that a Star Trek crew member visits Sunnydale and has to adapt to the whole demon - slaying thing. They could end up helping Buffy with some high - tech knowledge from the future.
One idea could be the Covenant from Halo encountering the Borg from Star Trek. The Covenant's religious zealotry and advanced technology would clash in an interesting way with the Borg's hive - mind and assimilation capabilities.
One idea could be a fanfic where Q takes a young Starfleet officer under his wing and shows them different timelines and alternate universes. It would be interesting to see how the officer reacts to all the chaos and knowledge Q presents. Another could be a story where Q is in love with a human from the Enterprise crew and has to navigate his omnipotent powers while dealing with human emotions.
One idea could be that the Covenant from Halo discovers the Federation in Star Trek. The different technologies and cultures would clash in really exciting ways. Maybe the Covenant would see the Federation's peaceful coexistence ideals as a threat to their religious beliefs.
