Naruto would face the challenge of raising a daughter in a world he doesn't fully understand. He may not be familiar with the education system in Annabeth's world, which likely focuses on things like mythology and combat training for demigods. Also, there could be political challenges. The demigod world may have its own power struggles and hierarchies, and Naruto being an outsider could be seen as a threat or at least a strange addition to the family dynamic.
Obviously, Naruto and Annabeth are main characters. Naruto as the father figure and Annabeth as his daughter. There might also be other characters from the Naruto universe like Sasuke or Kakashi who could be brought into the story to interact with the characters from the Percy Jackson world, like Percy himself or Grover.
In fanfiction, the idea of Naruto being Annabeth's father might start with a portal or time - travel element. For example, Naruto could be sent through a portal to the world of Annabeth. He might save her mother from a great danger, and in the process, they fall in love. Then, Annabeth is born. Another way could be that there is a curse or a prophecy that links their two very different worlds together, and Naruto is fated to be her father.
Well, in such a fanfiction, it might combine the universes by having Naruto's skills or values influence the world where Annabeth exists. Maybe Naruto's ninja way of never giving up is instilled in Annabeth. It could also be that Naruto has some kind of connection to the Greek gods in the Percy Jackson universe, which then ties him to being Annabeth's father in a really convoluted but interesting way.
It could also be someone new, a character created specifically for the fanfiction. Maybe a powerful new demigod who catches Annabeth's eye, and their relationship leads to the pregnancy.
In a fanfiction, Percy could become Annabeth's father in a magical realm where the rules of family and time are distorted. Maybe a powerful god or goddess messes with their destinies. Percy would then have to navigate the new relationship while still dealing with his own heroic duties. He might struggle to balance protecting her as a father and respecting her as an independent demigod who is used to taking care of herself.
In this fanfiction, a plotline could involve Percy having to introduce Annabeth to his side of the family. This would be really interesting as it would show a whole new aspect of Percy's world to Annabeth. Another plotline could be Annabeth getting into trouble at school or with other demigods, and Percy having to step in as her father to resolve the situation. This would show how he uses his influence and authority in this new role. There could also be a plotline where Percy and Annabeth find out that there's a prophecy related to their new relationship. They would then have to figure out what it means and how to fulfill or avoid it, which would add a lot of tension and mystery to the story.
Yes, in certain fanfictions. Fanfic writers like to play around with established concepts. They might see Kurama's close bond with Naruto and decide to create a scenario where Kurama is Naruto's father. This can lead to really interesting and unique story developments that deviate from the normal Naruto narrative.
There's a chance it could be a new character introduced in the fanfiction. Maybe someone who has a mysterious past and enters Annabeth's life briefly but leaves a big impact, resulting in her pregnancy.
The fanfiction might explore how Percy's relationship with other characters changes. For instance, he may have to face the judgment of Athena, Annabeth's mother, as he takes on the role of father. Athena could be skeptical or even hostile at first, but over time, Percy could prove himself worthy. Also, Percy would have to interact differently with his own friends and family, like his mother Sally, who might now be a grandmother - like figure to Annabeth.
