Jamie Lannister and Cersei Lannister are often seen as a complex pair. In some soulmate fanfictions, their twisted relationship could be explored in a different light, as if they were truly soulmates bound by some dark fate. And Bronn and a female character like Shae could also be an interesting pair. Bronn is a mercenary, and Shae was a prostitute, but they both understand the harsh realities of life, which could form a unique soulmate bond.
Sansa Stark and Theon Greyjoy could be an unexpected but interesting soulmate pair. Theon has a complex relationship with the Starks, and Sansa has grown into a strong woman. Their shared experiences could lead to a deep, soulmate - level connection. Also, Tyrion Lannister and Brienne of Tarth. Despite their differences, they are both outsiders in a way, and their mutual respect could be the basis for a soulmate relationship in fanfiction.
Jon Snow and Daenerys Targaryen can make an interesting soulmate pairing in fanfiction. They both have noble hearts and are leaders in their own right. Their union could bring about a new era in Westeros. Another could be Arya Stark and Gendry. They have a history together, and Gendry has always had a soft spot for Arya, which could be developed into a soulmate - like relationship.
Clark Kent and Arya Stark would be an interesting pairing. Clark with his superpowers and noble nature, and Arya with her assassin skills and strong will. They could learn a lot from each other. Clark could teach Arya about using her powers (if she were to gain some in this fanfic) for good, and Arya could teach Clark some of her stealth and combat techniques.
I think Iron Man and Tyrion Lannister would be a really interesting pairing. Iron Man is this brash, genius billionaire, and Tyrion is the clever, outcast dwarf in Westeros. They could bounce ideas off each other, with Iron Man showing Tyrion his high - tech gadgets and Tyrion teaching Iron Man about the political games in Westeros.
Another interesting pairing would be AOC and Arya Stark. Arya is a fierce and independent fighter. AOC could inspire Arya to think about the bigger picture in terms of changing the social order. Meanwhile, Arya could protect AOC from the many enemies she would surely make in the cut - throat world of Game of Thrones as she tries to implement her ideas.
Arya Stark and Morrigan. Arya is a skilled assassin in 'Game of Thrones' and Morrigan is a powerful witch in 'Dragon Age'. Their encounter could be really interesting. Arya might learn some new magical skills from Morrigan, while Morrigan could be intrigued by Arya's stealth and combat abilities.
Jon Snow and Elsa seem to be a popular pairing. The idea of the brooding and noble Jon with the powerful and reserved Elsa has a certain appeal. Their different worlds and personalities could create an interesting dynamic.
I think Jon Snow and Spock would make an interesting pair. Jon is a natural leader, and Spock's logical thinking could complement his more instinct - based leadership. They could learn a lot from each other, with Jon showing Spock about the harsh realities of a feudal society and Spock teaching Jon about the power of reason.
One underrated pairing could be Sansa Stark and Missandei. Sansa has grown into a shrewd political player, and Missandei is highly educated and close to Daenerys. They could bond over their experiences in the political and courtly arenas, and perhaps even form an alliance that could influence the power dynamics in Westeros.
One popular theme is the idea of star - crossed soulmates. For example, a character from a noble house and a commoner might be soulmates, but the class differences create huge obstacles. Another theme is the soulmate bond being tested by the power struggles in Westeros. Like how the battle for the Iron Throne can put a strain on a relationship between soulmates.
Some fans also like the idea of Tyrion Lannister and Dandelion from The Witcher being paired up in fanfiction. Tyrion's wit and Dandelion's charm could create some really humorous and interesting interactions. They could get into all sorts of mischief together in a crossover story.
Jon Snow and Daenerys Targaryen are quite popular. Their pairing in regular fanfiction was already big, and in slash fanfiction, it can take on new and different dynamics. Maybe a story where they are not just lovers but also have a more equal partnership in ruling the Seven Kingdoms, with a slashy undertone of deep emotional and physical connection.
