One popular one might be 'The Bond Beyond Worlds'. It explores their relationship in a really interesting way, showing how their different personalities interact. The author does a great job of creating tension and drama between them.
You can start by looking on Archive of Our Own (AO3). It has a vast collection of fanfics, and you can easily search for Nico and Percy - related ones there.
A fanfic that stands out is 'The Trio's Trials'. This one is interesting because it not only focuses on their physical adventures but also their emotional growth. We see Percy dealing with his leadership role, Thalia coming to terms with her past, and Nico learning to open up more. The character development throughout the story is quite engaging.
Maybe in the fanfic, Percy has some actions or characteristics that Nico doesn't like. For example, Percy might be too self - centered in the story, which goes against Nico's values. Or perhaps Percy has something that Nico desires, like more popularity or a closer relationship with a certain character, and that envy turns into hatred in the context of the fanfic.
One common theme is friendship. Since they come from different backgrounds within the demigod world, their journey to become friends is often explored. For example, in many fanfics, they start off not liking each other but gradually learn to respect and care for one another.
Writing fanfic involving sexual content is generally not appropriate. Fanfic should focus on positive aspects such as character development, friendship, and exploring different storylines within the boundaries of respect and legality. Such sexual content violates the ethics of creating fan - based works and can also be offensive to many readers.
The theme of acceptance is quite common too. Nico has had to deal with a lot of things that make him different, and Percy's acceptance of him is often a central part of the story. Also, loyalty is a big theme. They show loyalty to each other in various situations, whether it's in the face of danger or when dealing with other characters who might not understand their bond.
One common theme is friendship. Given their different backgrounds and powers in the Percy Jackson universe, exploring how they become friends or strengthen their friendship is often seen. For example, in many fanfics, they start off not understanding each other but gradually learn to respect and rely on one another.
One great 'Percy Jackson Nico' fanfic is 'The Son of Hades' series. It delves deep into Nico's character, exploring his powers and his relationships in a way that feels really true to the original series. The author has a great writing style that keeps you hooked from the start.
The camp leaders might betray them. If there is a power struggle within the camp, and Percy and Nico are seen as threats to the current leadership's power, the leaders could set them up. They could make it look like Percy and Nico are breaking camp rules or endangering the other campers, which would lead to the rest of the camp turning against them.
