A great fanfiction plot could involve Dany and Jon Snow discovering a long - lost magic that can help them defeat the White Walkers more effectively. They might go on a quest together, facing many challenges along the way, and during this journey, their relationship could deepen from mutual respect to love. This would add a new dimension to their characters and the overall 'Game of Thrones' universe.
One interesting storyline could be them uniting the kingdoms in a different way than in the original series. Maybe they find a way to combine their different leadership styles and bring about a more peaceful and prosperous Westeros. For example, Dany's experience with ruling different cities and Jon's knowledge of the North could create a unique form of governance.
Some fanfictions might explore a scenario where Dany and Jon Snow have to deal with a new threat that emerges after the events of the series. This threat could be a power - hungry lord who wants to take over the Iron Throne. Dany and Jon would have to use their wits, their armies, and their dragons (in Dany's case) to fend off this new adversary, all while navigating their complex relationship.
Another possible storyline is that Dany and Jon have to deal with the political aftermath of their relationship. There could be opposition from different houses who don't want a Targaryen - Stark union. They would then have to navigate through the complex web of politics, with Dany using her dragons as a show of force when necessary, and Jon using his diplomatic skills learned from the North. This would be a story full of intrigue, power plays, and of course, their undying love for each other.
One interesting scenario could be Dany and Jon teaming up to fight a new, unknown threat that emerges in the North, something more powerful than the White Walkers. They combine their forces and unique abilities, like Dany's dragons and Jon's leadership skills.
One interesting scenario could be Jon and Dany teaming up to fight a new, unknown threat that emerges in the East of Essos. They combine their military strategies, with Jon's knowledge of the North and Dany's experience with her Unsullied and Dothraki forces.
One interesting storyline could be Jon and Arya reuniting after a long time apart and teaming up to take on a new threat in the North. They might use their unique skills, Jon's leadership and Arya's assassin training, to protect their home.
Jon Snow is also a great character in fanfiction. Writers can expand on his relationships, especially with Dany. His sense of honor and duty can be further explored, and how it clashes or aligns with Dany's more ambitious goals. For example, in some fanfictions, he has to decide whether to support Dany's claim to the throne fully or try to find a compromise.
Tyrion Lannister would be a great addition. His wit and political acumen could serve as a counterbalance to Jon and Dany's more straightforward leadership styles. He could also offer valuable advice on how to deal with the various power - hungry lords in Westeros.
Often, it could be the remaining power - hungry lords and ladies who oppose Dany and Jon's rule. They might see Dany as a foreign invader and Jon as a threat to their own ambitions for the Iron Throne.
I really like 'Jon and Dany: The Unlikely Alliance'. This fanfic delves into how Jon and Dany might work together against the common threats in Westeros. It has some great action scenes and also explores their emotional bond. It gives more depth to their relationship compared to what we saw in the series at times. It's a great read for fans who wanted more of their interactions.
One interesting storyline could be Jon and Sansa ruling Winterfell together in a more harmonious way than in the show. They could face challenges from the remaining enemies in the North and strengthen their bond through mutual respect and strategic planning.
In some fanfictions, there could be a story where Arya and Jon discover a long - lost family secret that changes their understanding of their heritage. This could involve some sort of magical or political revelation that binds them closer together and gives them a new mission. For example, they might find out that there is a hidden power in their bloodline that can save Westeros from a greater danger.
