One interesting 'jon snow baby fanfiction' could be about Jon Snow having a baby with a character from another house, and the story revolves around protecting the baby from the political intrigue in Westeros. Maybe the baby has some special powers that make it a target.
One great baby Jon Snow fanfiction might be 'The Young Wolf's Beginnings'. It could explore his early days in Winterfell, his relationship with his family members like Ned Stark. Another could be 'Jon Snow: Infant of Prophecy' which delves into how his birth was a significant event even from a very young age. And 'Baby Jon's First Winter' might focus on his first experiences of the harsh winters in the North.
Well, in some fanfictions, the baby could be a symbol of hope. As Jon and Daenerys' child, it represents the union of two powerful houses. The baby might grow up to be a great leader, trained in both the ways of the Targaryens and the Starks. It could bring about new laws and a more just society, learning from the mistakes of the past rulers in Westeros.
Sansa Stark might be involved as well. Given her relationship with Jon Snow as his sister (though later revealed otherwise), she could play a role in protecting or being involved with the baby. Maybe she helps raise the baby in a world where Jon Snow is constantly facing threats.
In some 'Jon Snow harem fanfiction', the harem might consist of characters who are magically bound to him. Maybe they are all part of an ancient prophecy that links their fates to Jon's. This could lead to all sorts of adventures and political intrigue as Jon has to manage not only his new relationships but also the power dynamics that come with having such a diverse group of women around him.
In some 'Jon Snow Dragons' fanfiction, the dragons might be the key to Jon Snow's true identity. Maybe he is actually part of an ancient bloodline that has a special bond with dragons. As he discovers more about his connection with the dragons, he also uncovers secrets about his family and his destiny. This could lead to a whole new arc in his story where he has to come to terms with his new - found heritage and use it to save Westeros from impending doom.
One idea could be that the baby is born with a special ability, like being able to communicate with dragons even more so than Daenerys. Maybe the baby's presence unites the remaining kingdoms in a way that Jon and Daenerys alone couldn't. Another thought is that the baby becomes a symbol of hope for a new era, with people from all over coming to see the new heir of the Targaryen - Stark line.
One interesting fanfiction could be where Daenerys and Jon Snow team up to fight a new, unexpected threat in Westeros that is even more powerful than the Night King. In this story, they combine their unique skills and the power of their dragons to protect the realm.
In some fanfictions, the dragon egg might be the key to uniting the North and Daenerys. Jon Snow, being a Targaryen in some theories, has a special connection with the egg. It could hatch a dragon that recognizes Jon as its true master and helps him in his battles for the Iron Throne and the protection of the realm. This would be a major turning point in the power dynamics of Westeros.
In some fanfictions, Jon and Sansa form a strong emotional bond after all the hardships they've faced. They support each other through difficult times, like dealing with the aftermath of the wars. Their relationship deepens as they realize how much they rely on each other, not just as siblings but as two strong leaders of the North.
There could be a story where Jon Snow time travels to the era when the Wall was being built. He could interact with the builders, offer his skills and wisdom, and maybe even discover secrets about the Wall's construction that were lost over time. This would add a whole new dimension to the lore of Westeros.
