One great fanfiction could be where Jon Snow's twin sister plays a crucial role in the politics of Westeros. She might use her wits and charm to gain allies in King's Landing, much like Margaery Tyrell. Another idea could be that she has some hidden powers and uses them to protect Jon and their friends from the White Walkers. There are also fanfictions where she is a key figure in uniting the different houses against a common enemy.
A lot of fanfictions use the 'redemption' trope. Maybe she makes a mistake early on, like trusting the wrong person, and then has to redeem herself. There's also the 'forbidden love' trope. She could fall in love with someone she's not supposed to, like a member of a rival house. This adds a lot of drama to the story. Another popular one is the 'mentor - mentee' trope. She could be mentored by an old and wise character, like Brynden Rivers, and through that mentorship, she grows into a strong and capable leader in the world of Game of Thrones.
There's a fanfiction where Jon Snow's sister is a key figure in bringing about peace in the Seven Kingdoms. The story focuses on her diplomatic skills and how she uses her connection to Jon to unite different factions. It's really engaging as it gives a different perspective on the events of Game of Thrones, not just centered on the main characters we know from the show.
I'm not sure specifically if there is a well - known fanfiction with exactly that premise. However, given the popularity of both Jon Snow and the concept of deifying characters in fanfiction, it's very likely. Fanfiction writers often take beloved characters like Jon and put their own spin on them. They might give him god - like abilities such as super strength, the ability to control the elements, or even the power to see the future, which would completely change the dynamics of the story.
There's a fanfic called 'Jon and Ygritte: Beyond the Wall'. This piece focuses on their adventures together. It details how they hunt, survive in the harsh environment, and the small moments of tenderness they share. It gives a vivid picture of their life outside the normal Westerosi society, which makes their relationship even more interesting.
Some fanfictions focus on changing Jon's relationships. For example, they might create a closer bond between Jon and Sansa or Arya in ways that the show didn't explore. Others may change his backstory, like giving him a different mother or father figure. Many also give him new powers or abilities, such as enhanced combat skills or magical powers.
A very popular Jon Snow fanfiction is 'Jon Snow: The True Heir'. It plays on the idea of his true parentage and how that could change the power dynamics in the Game of Thrones realm. In this fanfic, he has to fight for his rightful place. Another one is 'Jon Snow's Unseen Path' which shows his journey through some less - explored aspects of the story. 'Jon Snow and the Alliance' is also quite good, where he forms unexpected alliances to survive the cutthroat Game of Thrones politics.
One common theme is his true parentage. Many fanfictions explore how his Targaryen heritage could have been revealed earlier or how it changes his relationships. Another theme is his leadership. Writers often show him leading the North in different ways, either more diplomatically or more forcefully.
One great Jon Snow Targaryen fanfiction is 'The Dragon's Heir'. It explores Jon's journey after learning his true heritage. The author beautifully weaves in his relationships with other characters, especially Daenerys. Another one is 'Snow of House Targaryen' which delves deep into how Jon copes with the political implications of being a Targaryen in a world that was so used to seeing him as a Stark bastard.
One possible fanfiction could be that Jon Snow discovers a long - lost magic that can actually communicate with the Night King. Instead of fighting, they have a series of intense conversations that make Jon understand the Night King's motives, which are not as simple as just bringing eternal winter. It could be that the Night King was once a hero wronged by the old magic and is now on a path of vengeance in a very twisted way.
