One common plotline is Percy feeling guilty about his feelings for Annabeth due to the age difference. He might try to suppress his emotions at first. Another is Annabeth using Percy's age and experience as a way to grow herself, like asking him for advice on various things. And sometimes, there are plotlines where the age difference causes problems in their relationship, such as others in the story disapproving of their relationship because of it.
Yes, in some fanfictions, Percy can be depicted as smarter. Writers might explore different aspects of his character, like his battle instincts translating into a different kind of intelligence compared to Annabeth's more academic and strategic smarts.
One implication could be that Percy has more experience and knowledge. Since he is older, he might have a deeper understanding of the world in the fanfiction. He could be more respected by others due to his age. Also, his relationships might be different. For example, if he has a relationship with someone younger, there could be a dynamic of mentorship or protection.
One reason could be to add a new twist to the story. By making Percy smarter, it changes the power dynamic between them and creates new plot possibilities.
Well, in fanfiction, anything can happen. There are fanfictions where the author wants to create a really unique scenario and might make Percy Jackson older than Chaos. But it's important to note that this goes against the traditional understanding of the Percy Jackson lore where Chaos is like the very first thing, the origin. But in the wild world of fan - created stories, the age relationship between Percy and Chaos can be flipped just for the sake of an interesting plot.
One scenario could be that Percy has some sort of magic spell cast on him that makes him smaller. Maybe a mischievous god or a powerful enemy uses a spell to shrink him for their own amusement or to gain an advantage in a battle. This would lead to some interesting situations where Annabeth has to protect him in a different way than usual.
It could be a symbol of vulnerability. Percy is often seen as the hero, but being smaller makes him seem more fragile. This can add depth to his character as he has to overcome not only the usual challenges but also the limitations of his new size. It also gives Annabeth a chance to be more of a protector, which is a role reversal that can be interesting to explore.
One implication could be a shift in the power hierarchy. Percy might have a different kind of authority or status. For example, he could be seen as a more dominant force among the supernatural beings.
Perhaps a plot where Percy has to use his age - related wisdom to prevent a war between the gods. Since he's older, he could have insights into their past mistakes and how to avoid repeating them. This would involve him traveling between different realms, using his wits and some new - found powers due to his age.
