Daenerys Targaryen and Rey are often combined. They are both strong female characters with special powers. Daenerys has her dragons and Rey has her connection to the Force. Writers like to explore how they would interact if they were in the same story.
Family also plays an important role. In 'Game of Thrones', family ties are complex and often a source of conflict or loyalty. In 'Star Wars', family, like the Skywalker family, has a huge impact on the story. In fanfiction, these family elements are often explored further, with crossovers creating new family dynamics between characters from the two universes.
Another theme is loyalty. In both franchises, loyalty is tested. In fanfiction, characters from both universes might have to decide where their loyalties lie when the two worlds collide. For example, a character from Star Wars might have to choose between helping a GoT house or following their own Jedi code.
One popular theme is power. Combining the power of the Force in Star Wars with the political and martial power in Game of Thrones makes for an interesting read. Another is the idea of loyalty, like how characters from both series deal with loyalty to their factions.
Well, it could be as simple as using the themes of heroism from '911'. In the Star Wars universe, you can have characters show the same kind of selfless heroism as the firefighters and police officers during '911'. For example, a group of rebels might sacrifice themselves to save a planet in a similar way.
Well, in a Naruto - Game of Thrones fanfiction, you could have the Sharingan (from Naruto) be a rare and mysterious power in the Game of Thrones world. Maybe a character discovers they have this power and it's seen as a sign from the gods. And then, just like in Naruto, there are different levels of power associated with it. This could lead to new alliances being formed as houses try to either control or protect the person with the Sharingan.
One way they could be combined is by having Aquaman's underwater world interact with the political intrigue of Westeros. Maybe the Iron Throne is made of some sort of magical material that has an effect on the seas, and Aquaman has to come to the surface world to deal with it. He could use his powers to navigate the complex power struggles, much like he does in his own underwater kingdom.
One way they can be combined is through exploring the themes of morality. In 'Game of Thrones', there are complex moral situations, much like in Christianity where moral teachings are central. For example, a fanfiction could focus on a character like Jon Snow and draw parallels to the Christian concept of sacrifice. Jon Snow often makes selfless decisions for the greater good, similar to the sacrifice of Jesus in the Christian faith.
The characters can be combined by having them team up. For example, Naruto and Luke Skywalker could join forces. Naruto's energy and determination along with Luke's connection to the Force would make a powerful duo. They could face common enemies like the Sith or rogue ninja. Another way is to have them teach each other. A Jedi could teach a ninja about the Force, and a ninja could teach a Jedi some ninja techniques.
You can have characters like Ash from Pokemon become a part of the Star Wars universe. He could be a young Force - sensitive being who uses his knowledge of Pokemon to his advantage. For instance, his Pokemon could help him in starship battles or in exploring new planets.
The 'culture clash' trope is quite popular. The different cultures in Star Wars, like the Jedi culture, and the cultures in Game of Thrones, such as the Dothraki culture, can create interesting situations when they interact. Another trope is the 'lost technology' in Game of Thrones being re - discovered by a Star Wars character. It's like a Star Wars engineer finding an ancient weapon in Westeros and trying to figure out how to use it. And the trope of 'fated enemies' can also be explored, where a character from Star Wars is fated to oppose a character from Game of Thrones due to some ancient prophecy or power imbalance.
