Perhaps the fanfic focuses on how Nico, being Percy's little brother, has to deal with the expectations that come with it. People might expect him to be as strong or as heroic as Percy right away. But Nico has his own journey. He might struggle with that at first, feeling a bit overshadowed. Then, as the story progresses, he could find his own way and make a name for himself, all while having Percy as his loving and sometimes overprotective big brother.
A very protective relationship from Percy. He would likely look out for Nico and keep him safe from harm. After all, Percy has a lot of experience in the dangerous world of demigods.
One common plotline is Nico getting into trouble and Percy having to rescue him. Since Nico is seen as the younger, more inexperienced one like a little brother, he might be a bit reckless and end up in a dangerous situation. Percy then uses his skills and experience to save Nico.
Well, often Nico is depicted as Percy's little brother in fanfictions in terms of their emotional bond. Percy might be protective of Nico. He could defend Nico from other threats or characters who misunderstand Nico. And Nico, in turn, would trust Percy completely, sharing his secrets and fears with him, just like a younger brother would with an older, more experienced sibling.
Well, they might be really immersed. They could be imagining themselves in the fan - created scenarios, getting excited about new plot twists that the fanfiction writers have come up with. Maybe they are sharing their favorite parts with each other, just like we do when we read really interesting books.
In many fanfictions where Percy Jackson is Nico's brother, it creates a whole new dynamic in the story. It often leads to different interactions with other characters. For example, their relationship with Annabeth might change. Percy could be more protective of Nico, and Nico might feel more secure having Percy as a brother. It also gives room for exploring their family history in new ways, like how they deal with their demigod powers together and support each other in the face of various challenges in the demigod world.
Well, it could be about Naruto being in the One Piece world and having to protect Nico Robin as his sister. Maybe they team up to fight against common enemies in both universes.
It depends on Percys' rules. If he is open - minded and thinks fanfiction can be a creative and fun extension of the original books, he might allow it. But if he has concerns about the quality or potential inappropriate content in some fanfictions, he may restrict it.
One common theme is the discovery of identity. Percy's child often has to figure out who they are in relation to their famous parent. Another theme is the inheritance of powers or abilities. Usually, they inherit some of Percy's powers and have to learn how to control them.
