There are many popular fanfictions featuring Percy, Thalia and Nico. Some might focus on their adventures together in the world of Greek mythology. For example, there could be fanfictions where they team up to face a new and powerful monster that the original books didn't cover. These fanfictions often explore their relationships more deeply, like the friendship between Percy and Nico which has a lot of room for development in fan - created stories.
One type of popular fanfiction could be those that explore alternate universes. In these stories, Percy, Thalia and Nico might have different powers or be in different situations. Maybe in one fanfiction, they are all part of a school for demigods that has a completely different set of rules and challenges. This allows the authors to play with the characters' personalities and backstories in new and interesting ways.
One interesting fanfiction could be about Thalia and Nico teaming up for a quest. In this story, they might start off not getting along due to their different personalities and pasts. Thalia, being bold and headstrong, and Nico, who is a bit more reserved and has his own dark secrets. But as the quest progresses, they learn to rely on each other and develop a deep friendship. Maybe they have to face some mythical creatures that neither of them has ever encountered before, and they use their unique skills to overcome the challenges.
One popular trope is the 'found family'. Given their complex relationships and backgrounds, many fanfictions explore how Percy, Thalia and Nico form a sort of family unit, supporting and protecting each other through various challenges.
Popularity of Percy, Nico and Thalia siblings fanfiction varies. There are those who adore the idea of reimagining their relationships in this way. It gives writers a chance to delve deeper into their backstories and how they would support or conflict with each other as siblings. For example, Percy's leadership and Nico's more brooding nature, along with Thalia's fierceness could create really interesting family - oriented story arcs. Plus, fans who love the characters are always eager to see new angles on them, which makes this type of fanfiction appealing to a segment of the fanbase.
One common theme is the exploration of their powers. When banished, they are often in situations that force them to use their powers in new and unexpected ways. For instance, Percy might have to use his water powers in a place without much water, so he has to find creative ways to access it. Also, the theme of redemption can come up. Maybe they were banished because of something they did wrong, and the fanfiction is about them making amends. Another theme could be the discovery of new secrets. The place they are banished to might hold secrets that are related to their past or their powers.
They could be like siblings. Percy and Thalia might act as the older siblings, protecting and guiding Nico. Percy, with his leadership skills, and Thalia, with her combat abilities, would be great at looking out for the younger Nico. They could also be like cousins, with a close - knit bond but still having their own individual family heritages that sometimes create interesting dynamics.
I'm not sure of specific titles off the top of my head, but you can usually find great ones on fanfiction.net or Archive of Our Own. Just search for their names and you'll likely come across some highly rated ones.
One challenge is the jealousy of other gods. Since they are new gods, the older, more established gods might not like the attention they get or the new ideas they bring. Another challenge is controlling their powers. As mentioned before, going from demigod to god means a huge jump in power level, and it's not easy to get used to. For example, Percy might accidentally flood a city while trying to create a small puddle for fun.
One way to find popular 'Percy and Nico leave' fanfictions could be to check out fanfiction communities and forums dedicated to the Percy Jackson series. Fans there often recommend their favorite stories. It's possible that some fanfictions might involve them leaving because of a prophecy they need to fulfill on their own, away from the influence of the gods or other campers. Another scenario could be that they leave due to some sort of conflict within the camp that they can't resolve while staying there.
One popular trope is the 'Chosen by Chaos' trope. For example, in many fanfictions, Percy, Nico or Thalia are chosen by Chaos for a special task. It gives them extraordinary powers and sets them on a grand adventure. Another is the 'Power - up' trope where they gain new abilities from Chaos.
One common trope is the 'Power of Friendship'. In many fanfictions, the strong bond between Percy, Annabeth, Thalia and Nico helps them overcome impossible odds. For example, they might be facing a powerful enemy but their trust in each other gives them the strength to keep fighting. Another trope is 'Character Growth'. Fanfics often show how each character, like Nico evolving from a somewhat withdrawn figure to a more confident hero.
