Jon Snow and Alistair. Jon Snow is a noble and strong leader in 'Game of Thrones'. Alistair is a key character in 'Dragon Age'. They could bond over their leadership experiences. Maybe they'd go on a quest together, with Jon Snow's knowledge of survival in the harsh North and Alistair's training as a warrior coming in handy.
Daenerys Targaryen and Flemeth. Daenerys has her dragons and is a conqueror. Flemeth is an ancient and powerful being in 'Dragon Age'. Their meeting could be a clash of two powerful female forces. Daenerys might seek Flemeth's wisdom, while Flemeth could see Daenerys as a potential tool or threat in the grand scheme of things.
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.
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.
A fanfic could focus on the dragons in both worlds. In 'Game of Thrones', Drogon and his siblings are unique. In 'Dragon Age', there are different dragon types. The story could explore how the dragons from the two worlds interact. Perhaps a character tries to tame a 'Dragon Age' dragon using the knowledge of dragon taming from 'Game of Thrones'.
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.
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.
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.
Definitely Jaime Lannister. His character had a lot of development in the original series. If reincarnated, he could either redeem himself even further or take a completely different path. He might try to make amends for his past actions by becoming a true knight, or he could turn against his family if he realizes the toxicity of their ways. His reincarnation would bring a whole new set of possibilities to the story.
I think Bran Stark could be very interesting too. As the Three - Eyed Raven, he has vast knowledge and powers. In a future fanfic, he could use his powers to foresee and prevent new disasters or to guide the future of Westeros in a more positive direction. However, his new powers might also make him a target for those who fear his influence.
Caroline Forbes from the Originals and Luna Lovegood. Caroline is a strong - willed vampire, and Luna has her own unique view of the world. They could bond over their differences from the norm in their respective worlds. Caroline could be intrigued by Luna's dreamy nature, and Luna could be fascinated by Caroline's vampiric abilities.
In a crossover with 'Naruto', Soma could be paired with Naruto. Naruto's love for ramen could lead to some interesting interactions with Soma's cooking skills. They could have a friendly cooking competition where Naruto tries to use his ninja skills to enhance his cooking speed. Another interesting pairing could be Erina with Sakura. Sakura could learn about high - class cooking from Erina while Erina could be impressed by Sakura's medical knowledge which could be applied to food science in some ways.
