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 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.
He's also a quick thinker. When faced with problems, he doesn't waste time panicking. Instead, he immediately starts coming up with possible solutions. For example, if there's a sudden danger in the fanfiction world he's in, he'll think on his feet and find a way to either avoid it or turn it to his advantage. And he's resourceful. He uses whatever he has around him, whether it's knowledge, objects, or the skills of his companions, to achieve his goals. He might combine different ideas and resources in unexpected ways to show his hidden intelligence.
One great story could be where Percy uses his hidden intelligence to solve a complex mystery in his school. He might have been underestimated by his classmates, but when a valuable item goes missing, he pieces together the clues that others overlooked. For example, he notices small details like footprints and a strange smell in the hallway, leading him to the culprit.
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.
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.
It could be that Annabeth has a misunderstanding about Percy. She might think he's a threat to her position or status at the camp, so she bullies him to try and keep him in check.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
Percy might be a bit flustered and embarrassed. He's protective of his relationship with Annabeth, so having Magnus walk in might make him feel like their privacy has been invaded. He could quickly try to shield Annabeth or just look really shocked.
