In some fanfictions, Gendry is paired with Melisandre. Given her mysterious nature and her past interest in Gendry in the show, it makes for an interesting pairing. Their relationship could be explored in terms of power, magic, and the manipulation that might occur between them as they navigate the complex world of Westeros.
Arya is often paired with Robb. They have a strong bond as siblings, and in fanfiction, they might team up to take revenge on their enemies or work together to restore the Stark family's honor. Arya's skills as an assassin could be very useful in Robb's campaigns.
Sansa Stark is often paired with Ramsay in fanfiction. Their relationship in the original series was extremely dark, and in fanfiction, some writers might explore a different side of it, like Sansa finding a way to manipulate Ramsay or even Ramsay having some strange form of obsession with her that goes beyond his usual cruelty.
Definitely Tony Stark and Tyrion Lannister. They are both intelligent, witty, and a bit of an outcast in their own worlds. Fans love to imagine them coming together, sharing their knowledge and maybe even coming up with some grand plans to either take over Westeros or save the world from some new threat.
One of the most common pairings is between Daenerys Targaryen and Spartacus. Daenerys is a powerful leader with her dragons, and Spartacus is a symbol of the fight for freedom. A fanfiction could explore how they join forces, with Spartacus' gladiators and Daenerys' Unsullied fighting side by side. Also, Jon Snow and Agron are sometimes paired. Jon Snow's sense of duty and Agron's loyalty could be combined in a story where they lead their respective groups in a great battle against a common enemy.
Jon Snow is another character that might be paired with Asher. They are both outsiders in a way. Jon being a bastard and Asher having his own family issues. They could bond over their shared experiences and fight together against the common threats in the Seven Kingdoms, like the White Walkers or the power - hungry lords.
Jon Snow is often paired with them. His relationship with Daenerys in the show makes it a popular choice in fanfiction. He could team up with Daenerys and Drogon to fight against the White Walkers in new and exciting scenarios that were not shown in the original series.
Jon Snow is another character often paired with Arya in fan fiction. Since they are siblings in the series, some fan fictions might explore a deeper bond between them, like Arya joining Jon in his battles against the White Walkers or them working together to reclaim the Iron Throne for their family.
One common theme is the idea of redemption. Gendry, having a somewhat troubled past, might find redemption through his relationship with Arya. Another theme is the growth of their characters. As they interact more in fanfiction, they both become more well - rounded. And of course, love is a big theme. Whether it's a slow - burning love or a sudden realization of their feelings, it's often at the center of these stories.
Daenerys Targaryen is often made into an overpowered character in fanfiction. Her already - strong position in the series can be amplified, like giving her the ability to control all dragons at once without any limitations, instead of the gradual growth in power she had in the original story.
Definitely Harry Potter and Daenerys Targaryen. Harry is the hero of his world and Daenerys is a powerful queen. Their meeting could lead to all sorts of interesting stories, like them sharing their experiences of leading and fighting for what they believe in.
