Well, it's possible that such a fanfiction exists given the creativity of fanfiction authors. They like to experiment with different relationship dynamics. But considering the popularity and the nature of Annabeth and Percy's relationship in the source material, this would be quite a shocker. It could also attract a lot of criticism from fans who are attached to the original relationship, while others might be interested in seeing how such a different plot would unfold.
One interesting aspect of this fanfiction could be how a mortal might view Percy and Annabeth's extraordinary abilities. A mortal might be in awe of their combat skills. For example, seeing Percy control water during a fight or Annabeth's strategic planning. They would also notice their strong bond, which might seem otherworldly to an ordinary person.
Their demigod past can give them unique skills. Percy's ability to control water, even if it's not as powerful in the mortal world, can still help him in situations like dealing with a flooded basement or helping at a local pool. Annabeth's strategic mind from her demigod battles can make her excellent at things like planning community events or solving problems at work.
In the fanfiction, Percy's interaction with Annabeth's mortal friends could start off a bit rocky. He might be seen as the odd one out, especially if he's just met them. But as time goes on, he could bond with them over shared interests. Maybe they all like the same kind of food or music. And his relationship with Annabeth would play a role too. If Annabeth is really close to these friends, Percy would make an effort to get along with them for her sake, and in the process, form his own unique relationships with them.
A possible plotline could be a mortal who becomes friends with Percy and Annabeth without knowing their true nature at first. As the story progresses, they start to notice strange things about their friends. Another plotline could involve a mortal who is caught in the middle of a demigod battle. They have to rely on Percy and Annabeth to keep them safe while also trying to understand what's going on.
One plot idea could be Percy and Annabeth starting a new life in a small town. They could face challenges like dealing with normal high school drama while still having their heroic instincts. For example, they might have to stand up to a local bully who is causing trouble for the other students. Another idea is them going on a road trip across the country, exploring different places and having adventures that are more grounded in the mortal world, like getting lost in a big city and having to find their way back using only their wits.
When Percy's mortal friends first meet Annabeth in fanfiction, it could be in a busy place like a park or a coffee shop. Percy's friends would likely be struck by Annabeth's beauty and intelligence. However, they would also sense her wariness. Annabeth, on the other hand, would be cautious about revealing too much to these mortals at first. As they start to talk, the friends might ask her about her relationship with Percy, and Annabeth would have to be careful with her answers to protect their world of demigods from being exposed.
In a large number of Percy and Annabeth fanfictions, they are indeed presented as soulmates. Their shared adventures, the way they understand each other without many words, and the deep loyalty they have for one another all contribute to this perception. Fanfiction authors often build on their existing relationship from the original works and enhance it to the level of soulmates. They might show it through things like Percy being able to sense Annabeth's distress from afar, or Annabeth always knowing exactly what Percy needs in difficult situations. This soulmate - like relationship makes for very engaging and heart - warming stories in the fanfiction realm.
I think it's an out - of - the - box concept. It could potentially be a way to show a different side of the characters, but it also risks ruining the integrity of their relationship. It's not a typical or pleasant idea considering how much fans adore Annabeth and Percy together. It might be a concept that only a small number of writers who want to be edgy or create a lot of shock value would explore.
