He might try to understand the motivation behind it. Maybe he'd think that the author had some issues or was just exploring different ideas. He could approach it from an empathetic angle, but still be firm in his own self - identity and not let it affect him too much.
Percy would probably rely on his friends. In the Percy Jackson series, his friends were always there for him. In this fanfiction situation, he'd need them more than ever. They could help him stay grounded and remind him of his true self, not the dark legacy of Voldemort. Also, he might learn more about his demigod side to overpower the dark side in him.
The author can keep the core elements of the Percy Jackson mythology intact. For instance, the existence of the gods, the demigod powers, and the various monsters. But they can add a new layer to it by exploring how female Percy Jackson's sexual orientation affects her relationship with the divine world. Maybe some gods are more accepting than others, and this could create new conflicts or alliances.
A fanfic could handle Annabeth's death by showing Percy's emotional journey. It could start with his denial, then his anger, and finally his acceptance. The writer could also focus on how the other characters support him during this difficult time.
Percy could start to form new relationships within the Faunus community. These relationships could teach him different values and ways of life. Maybe he'd meet a Faunus mentor who would help him understand and control his new Faunus powers, if he has them. This would be a big part of his development, as he'd be learning from a completely different perspective than he's used to at Camp Half - Blood.
It could be a powerful, ancient Titan who was banished long ago and has now returned for revenge. Maybe Kronos has an even more evil and powerful form that he takes on, becoming the Dark Lord. He wants to destroy the new order of the gods and demigods that has been established since his last defeat.
Fanfiction can enhance the reading experience of the Percy Jackson books by giving you more variety. The original books have a set plot and set of characters. Fanfiction can introduce new characters that fit into the Percy Jackson world or give existing characters new traits. This can make the world seem more alive and complex. Also, reading fanfiction can make you look forward to re - reading the original books. You might notice things in the original that you didn't before because of something you read in a fanfic. For example, a fanfic might focus on a particular magic item in the Percy Jackson world, and when you go back to the original books, you'll pay more attention to that item.
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.
Well, it's a great way to see different perspectives. The original Percy Jackson books have a set view of the characters and the story. But fanfiction can take those elements and remix them. You might find a fanfic that makes Percy interact with a character in a completely new way. It can also be a fun way to be part of a community. When you read fanfiction, you can join discussions about different stories, share your thoughts, and connect with other fans who have similar interests.
One interesting concept could be a darker version of Percy's powers. For example, instead of just controlling water, he might be able to use it in more menacing ways, like creating water blades that can cut through almost anything. Another concept could be a darker side to his relationships. Maybe his friendship with Grover takes a turn, and there's more conflict and distrust. Also, a darker Percy might have a different view on the gods, perhaps feeling more resentful towards them for all the hardships he has faced, instead of just being the hero who blindly follows their orders.
He might be shocked and a bit disturbed. Percy is a heroic character, and seeing a 'dark' version of himself in fanfiction would be quite jarring. It's like looking into a distorted mirror of his identity.
