His hidden talent might be the power to manipulate water in ways other than just controlling it for combat. Maybe he can transform water into different shapes or substances on a molecular level in fanfiction. So he could turn water into a solid shield that is stronger than normal ice, or he could create a mist that can carry messages or images, like a magical water - based hologram.
In some fanfictions, Percy's hidden talent could be related to his heritage in a new way. For instance, since he is a son of Poseidon, he may have the ability to tap into the primordial energy of the sea that was present before the gods. This would allow him to access ancient powers that are far greater than what he has shown so far, like being able to create new islands or reshape existing ones.
When Percy has a hidden talent like the ability to teleport through water in fanfiction, it completely changes the dynamics of the story. It means he can quickly get to places that were previously hard to reach. This can lead to new adventures in far - flung locations. He could suddenly appear in a lost underwater city to save his friends or reach a secret island to find a powerful artifact, and this would drive the plot forward in unexpected and exciting ways.
If Percy Jackson were to become a hidden god in fanfiction, it would likely involve a lot of mystery and suspense. He'd have to navigate a world where he couldn't reveal his true nature easily and could potentially uncover some dark secrets along the way.
In this fanfiction, the plot could be that the hidden blades were once used by an ancient hero in the Percy Jackson universe. Percy stumbles upon them in an old, forgotten temple. However, the blades are cursed. Every time he uses them, he starts to lose his memory bit by bit. He has to find a way to break the curse and still use the blades to defeat a powerful enemy that is on the verge of awakening an ancient evil.
A great main villain could be a rogue demigod who has found a way to corrupt the power of the hidden blades. This demigod could be jealous of Percy's fame and power and uses the blades to create chaos among the demigod community. He might be using the blades to steal the powers of other demigods, making him stronger with each theft.
Maybe Percy's secret talent in fanfiction could be that he has the ability to communicate with sea creatures on a much deeper level than shown in the original story. He can not only understand their simple messages but also have complex conversations with them, getting valuable information about hidden treasures or upcoming threats in the ocean.
Some fanfiction authors use the concept of Percy Jackson Champion of Light to create crossovers. For example, they might combine the Percy Jackson universe with the world of Harry Potter. This can lead to really interesting scenarios where Percy has to interact with wizards and deal with magical threats that are different from the ones he's used to in his own world.
Well, sometimes in fanfiction, his brother might be a mortal who discovers his demigod heritage later. This could add an interesting twist to the story as he has to adapt to the world of gods and monsters. Or it could be a long - lost half - brother from a different camp, like a son of Poseidon from another part of the world who was hidden away for some reason.
Another angle in these fanfictions could be Percy's impact on the reputation of the Hunt. Since he is a well - known figure, his association with the Hunt might attract more attention, both good and bad. This could create all sorts of new plotlines and challenges for the characters.
Some minor gods related to the earth like Demeter could be allies. She has her own powers over the earth and could teach Percy some of her techniques. Also, the nymphs, such as the water nymphs and the tree nymphs, could be allies. The water nymphs could help with the water sources within the earth (like underground rivers) and the tree nymphs could help Percy take care of the forests. And let's not forget the pegasi. They could be used for transportation when Percy needs to quickly travel across his earthly domain.
Annabeth could definitely be one of his main allies. Her intelligence and strategic planning would be invaluable in a fight against Olympus. Also, Grover might be there, using his skills as a satyr to gather information and support from other nature - related beings. Some of the less - well - known demigods from Camp Half - Blood could also join in, seeing Percy as a chance for a new order.
