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.
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.
One popular trope is the 'lost heir' trope. In many fanfics, a character is revealed to be the long - lost heir to a great house or even the Iron Throne. This adds an element of mystery and drama. Another is the 'undercover hero' trope, where a character pretends to be someone they're not in order to achieve a greater good. For example, a spy within a rival house.
One popular trope is the 'stranger in a strange land'. Vikings arriving in Westeros or vice versa, and having to navigate the new and often dangerous culture. For example, a Viking warrior might struggle to understand the complex politics of the Seven Kingdoms in 'Game of Thrones'.
The 'romantic crossover' is also quite popular. A character from Game of Thrones might fall in love with a character from Elder Scrolls. This can lead to all sorts of interesting plot developments as they come from different cultures and backgrounds. It also allows for exploration of the different concepts of love and relationships in both universes. For instance, the arranged marriages in Game of Thrones contrast with the more diverse forms of relationships in Elder Scrolls.
One popular trope is the 'fish - out - of - water' story. For example, a character from Elder Scrolls suddenly finds themselves in the unfamiliar and often brutal world of Game of Thrones. Another is the power - sharing trope, where a character from Elder Scrolls with special powers teams up with a Game of Thrones character to gain more power or to fight a common enemy.
One popular trope is the power - up trope. For example, a character from Naruto might gain the ability to use the Force from Star Wars, and then use it to upgrade their existing ninja powers. This often makes for an exciting read as the character becomes super - powerful in a new and unexpected way.
One popular trope is the 'fish out of water' story. For example, a Viking suddenly finding themselves in the complex political world of Game of Thrones. Another is the power - hungry character from one universe trying to take over in the other. It adds an element of conflict and drama.
One popular trope is the 'fish out of water' scenario. A character from one universe suddenly finds themselves in the other and has to adapt quickly. For example, a Warhammer dwarf in Westeros might be shocked by the lack of mountains and underground cities. Another trope is the 'power - up' where a character gains new abilities or weapons from the other universe. A knight in Game of Thrones might get a powerful Warhammer - style weapon and become nearly invincible.
One unique element is the combination of different forms of power. For example, the Force from 'Star Wars' and magic in 'Game of Thrones'. Another is the clash of cultures. The chivalrous Jedi and Sith from 'Star Wars' are very different from the noble houses and their political games in 'Game of Thrones'.
The 'power couple' trope also exists. Two female characters coming together and using their combined wits and influence to navigate the dangerous political landscape of Westeros. For example, characters like Sansa and Margaery might be paired in fanfic in this way.
