Percy might visit some new and unknown parts of the Camp Half - Blood. There could be a hidden area that holds secrets about his past or the future of the demigods. He could meet new characters, both friendly and hostile, as he explores this uncharted territory. He may also have to deal with some internal struggles, like his fear of losing his powers or his friends.
In a summer vacation fanfiction, Percy could be sent on a diplomatic mission to another camp of demigods. This other camp could have different rules and customs. Percy would need to adapt and try to build an alliance. Along the way, he would face misunderstandings, jealousies among the demigods, and also external threats like attacks from mythical beasts that target both camps.
Once upon a time during summer vacation, Percy Jackson decided to visit a secluded beach. He thought it would be a peaceful getaway. But little did he know, strange sea creatures lurked beneath the waves. As he swam, he noticed a shimmering cave. Curiosity got the better of him, and he swam inside. There, he found an ancient trident, which seemed to have a strange power. Percy knew he had to figure out what it was all about before any monsters came looking for it.
In a Percy Jackson family vacation fanfic, there could be a lot of adventure. For instance, they could be traveling through a forest and stumble upon an ancient, lost temple. Inside, there are puzzles and traps that they have to overcome together as a family. Percy would use his skills, his mom could offer her wisdom, and Poseidon might show up to help at a crucial moment. And of course, there would be some humorous moments, like when they try to cook normal food but end up with some sort of magic - infused meal because of a spell gone wrong.
In the 'Percy Jackson Disappears' fanfiction, perhaps Percy could be kidnapped by an unknown enemy. Maybe it's a new villain who has a vendetta against the demigods. This would lead to his friends, like Annabeth, going on a desperate search for him, facing many dangerous challenges along the way.
In fanfiction, Percy could be in the hospital because he was captured by an enemy and tortured. Now he's there being healed by the camp's healers or some advanced demigod medical technology. Another possibility is that he's having some sort of identity crisis related to his demigod status and it's causing him physical and mental stress, so he's in the hospital for both medical and psychological help.
They might go on an adventure together. Maybe they discover a hidden beach or a mysterious cave. They could also have some really deep conversations about their past experiences and their future plans.
Well, in this fanfiction, Percy's immortality could lead to some really interesting character development. He may start to feel lonely as he realizes that he will outlive all of his friends. This could cause him to be more withdrawn at first. But then, as he interacts with the students at Westover Hall, he might find new meaning in his immortality. He could start to see it as a way to protect others not just for a short time, but for as long as he exists. He could also form deep and lasting friendships with those who accept him for who he is, regardless of his immortality.
In the fanfiction, Percy might face new challenges related to his demigod status. Maybe he has to deal with the aftermath of the war, like rebuilding Camp Half - Blood or helping new demigods adjust.
Well, he could end up in a situation where all his friends are incapacitated. For example, they are put under a powerful spell. Percy then has to be the lone warrior to fight against a group of evil demigods who are trying to take over Camp Half - Blood. He'd have to use his water - related powers in new and creative ways.
He might go on a solo adventure to discover more about his powers. He could encounter new mythical creatures that he hadn't seen around the camp. Maybe he'll meet some other demigods who are on the run or have their own secret quests.
Well, in this fanfiction, Percy controlling the Styx could lead to some really interesting plot developments. Since the Styx has such a significant role in Greek mythology, it could attract all kinds of mythical creatures and gods. Percy could find himself in the middle of a power struggle as different factions either try to use him or stop him. He might also use the Styx to travel to different realms or access hidden knowledge. And perhaps he would have to face the consequences of messing with such a powerful and sacred entity, like facing the wrath of Hades or other underworld deities.
