Another idea for the fanfic could be that they are on a quest. They are searching for a lost artifact or trying to rescue someone. Along the way, they face various mythical creatures and obstacles. The fanfic could detail their individual growth as characters during this quest, how they become better versions of themselves through their experiences with each other.
It might also be a story about their relationships. Perhaps there are tensions between them at first. Percy's status as a champion might make Thalia a bit jealous or Zoe might be skeptical of his abilities. But as the story progresses, they learn to trust and rely on each other, forging a strong friendship.
A simple plot could be a race against time. They have to reach a certain place before an evil force does. Thalia could use her speed and strength, Percy could use his strategic thinking as a champion, and Zoe could use her knowledge of the terrain to lead them. They might encounter traps and minions of the evil force along the way.
Well, another place to look could be Tumblr. There are often writers who post snippets or links to their fanfics on there. Some Tumblr communities dedicated to the relevant fandom might be a good source. However, the content on Tumblr can be a bit scattered, so you may need to do some digging. But it's definitely worth a shot if you're looking for unique takes on Thalia, Percy and Zoe in fanfic form.
Redemption is another theme that pops up. Maybe Zoe has made some mistakes in the past, and fanfics could explore her path to redemption. Or perhaps Percy has to atone for something, and how Thalia and Zoe play a part in that. There's also the theme of family, not in the traditional sense always, but like a found family. Since they are comrades in their adventures, they can form a strong family - like bond, and fanfics often explore the dynamics of such a relationship.
Zoe could become more withdrawn initially. Losing Percy, who was perhaps a close friend or love interest, would be a huge blow. But then, she might slowly turn her grief into strength. For example, she could become more determined in her fights, using Percy's memory as a source of inspiration.
In this fanfic, Percy, Thalia, and Nico find themselves on a quest together. Along the way, they start to bond like a family. Percy shares his stories of the sea, making Nico laugh with his tales of sea monsters. Thalia shows them her skills in archery, and they all learn from each other. At night, they sit around the campfire, sharing their hopes and fears. Nico reveals his insecurities about his powers, and Percy and Thalia offer their support, telling him he's an important part of their 'family' of demigods.
In a fanfic about Percy and Thalia's fight, it could start because of a misunderstanding. Maybe Thalia thinks Percy is getting too much attention from the gods and she's jealous for the sake of all the half - bloods. Percy, on the other hand, might not understand why Thalia is so hostile all of a sudden.
Percy as Zoe's father in fanfic could be a really interesting concept. If it's in a fan - made story, perhaps Percy has certain traits that are passed on to Zoe. Maybe he's a heroic figure, and Zoe inherits his courage. But again, we need to know more about the fanfic. Is it based on a fantasy world? A sci - fi setting? That would change how we view Percy and his role as Zoe's father.
In Percy and Thalia lemon fanfic, Percy and Thalia often have their characters explored in unique ways. Usually, their relationship might be depicted with more depth and complexity than in the original works. For example, their interactions could be centered around some special adventures where they rely on each other more. This kind of fanfic may also play with their individual powers and how they complement each other during difficult situations.
Another reason could be different loyalties. Thalia has her own group of friends and allies, and Percy has his. There could be a situation where their friends' actions or needs put them at odds with each other. For example, if Percy's friends get into trouble with something related to Thalia's friends' territory or interests, it could spark a fight.
No, it's not appropriate. Writing sexual fanfics about characters is unethical and often violates the terms of use of many platforms. It also objectifies the characters and can make other fans uncomfortable.
