Yes, there might be. The world of fanfiction is vast and diverse, and crossovers between different fictional universes like Harry Potter and Naruto (where Sasuke is from) are not uncommon. Some fans enjoy creating unique relationships between characters from different series, so it's very possible that there is a fanfic exploring the idea of Harry being Sasuke's cousin.
You can start by looking on popular fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. Just use the search bar and type in relevant keywords like 'Harry', 'Sasuke', and 'cousin'. However, it might be a bit of a hunt as there could be a large number of fanfictions to sift through.
In this type of fanfiction, it could be really interesting. Harry might bring his own set of skills and a different perspective into Sam and Dean's world. Maybe he'd introduce some unique magic that could help them in their hunts. For example, he could use spells to track down monsters more easily or protect them from certain types of dark magic that they haven't encountered before. It would be a cool crossover, mixing the world of Harry Potter with the Supernatural universe.
Well, a plot could revolve around Naruto and Sasuke growing up together more closely because of their family relation. Naruto could be more aware of Sasuke's family situation from the start. This might lead to Naruto trying to prevent the Uchiha massacre. He could use his influence as a cousin to bring Sasuke closer to the village earlier, changing the whole dynamic of the story. Maybe they even train together under new family - related training methods.
In the context of fanfiction, if Harry Potter is Percy Jackson's cousin, it might involve a crossover of the magic systems. Harry's world has wizards, magic wands, and spells like the Patronus Charm. Percy's world has demigods, with powers related to their godly parents. A possible way for them to be cousins could be through some ancient magic or prophecy that ties the wizarding world and the world of Greek gods together. Maybe there was a wizard in the past who had a connection with a demigod, and over generations, this led to Harry and Percy being related.
One possible aspect of this fanfiction could be exploring their family dynamics. Maybe Harry, being from the wizarding world, has a different upbringing compared to Jacob. Their relationship might be filled with moments of discovery, as they learn about each other's worlds. For example, Harry could introduce Jacob to some basic magic tricks, while Jacob could share stories about his Muggle life. It could also involve them facing some sort of common enemy together, relying on their unique skills from their respective worlds.
Yes, there are likely some fanfictions out there with this concept. The Percy Jackson and Harry Potter universes are both very popular, and fans often like to cross - over characters in interesting ways, such as making Percy and Harry cousins. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net to find such stories.
Well, in this fanfiction scenario, Annabeth Chas being Bella's cousin could add a whole new dynamic. Maybe Annabeth brings her own set of skills and knowledge into Bella's world. For example, if this is in a world related to some sort of supernatural or adventure setting, Annabeth's experience could help Bella out in tricky situations. It could also lead to interesting family interactions, like family secrets being shared or family feuds that need to be resolved.
In this fanfiction, it could start with a strange portal or some sort of magic that links the two universes. Naruto might be shocked to find out he has a Saiyan cousin. Vegeta, on the other hand, would probably be initially dismissive. But as they get to know each other, they could learn from each other's fighting styles. Naruto could teach Vegeta about the importance of friendship in battle, while Vegeta could show Naruto some of the more advanced energy - based attacks of the Saiyans.
In a fanfiction, Sasuke and Sakura might be protective of Naruto in a more emotional sense. For example, when Naruto is doubting himself due to some rumors in the village. Sakura would be the first to stand up for him, using her sharp tongue to put the rumor - spreaders in their place. And Sasuke, in his own quiet way, would show his support by training with Naruto extra hard, as if to remind him of his strength.
Yes, there are likely fanfictions with such a plot. Fanfiction writers often come up with creative and unexpected scenarios for popular characters. In these stories, they might explore how Naruko and Sasuke keep their marriage a secret, perhaps due to political reasons or to protect each other from enemies. It could also involve their friends gradually finding out about the relationship and their reactions.
