Percy's family members could be in the fanfiction too. His mom, for example, would be worried sick if Percy started ignoring everyone. She'd be trying to figure out if something happened at school or with his friends. His dad, Poseidon, might also play a role, perhaps sensing Percy's distress from afar and trying to intervene in some way.
Annabeth would definitely be involved. As Percy's girlfriend, she is often by his side during his adventures. She could be the one who witnesses Poseidon's pride towards Percy and helps Percy understand the significance of it. Grover, Percy's best friend, is also likely to be there. He might provide some comical relief during the serious moments when Poseidon is showing his pride. Also, other demigods from Camp Half - Blood like Jason, Piper, and Leo could be involved. They could be in awe of Percy's new - found status with Poseidon and might interact with him differently because of it.
There could be the typical Dragonborn - associated characters. Maybe characters like Delphine, who often plays a role in guiding the Dragonborn. Since Percy is now the Dragonborn, she might interact with him in different ways compared to the original game.
Well, aside from Percy, Annabeth is likely to be a main character. She would probably be concerned about Percy's acceptance of godhood and try to influence his decisions. Grover might also be there, as Percy's long - time friend. He could provide support or comic relief. And then, Poseidon, Percy's father. He would have his own thoughts on Percy becoming a god. Maybe he's proud but also worried about how Percy will handle the power.
There could be a new character, a jailmate of Percy. This character could be either a friend who helps Percy survive in jail or an antagonist who makes his life more difficult. For example, a tough guy who wants to bully Percy at first but later has a change of heart.
Another character could be Annabeth. She might try to stop Percy from taking such extreme actions, or she could be on his side if she believes the hunters are in the wrong. Grover could also be there, trying to play the peacemaker between Percy and the hunters. And then there could be some new, made - up characters in the fanfiction, like a rogue hunter who sides with Percy or an antagonist within the hunters' ranks who pushes Percy to his limits.
Family members, if he has any in the fanfiction world, would be devastated. His mother, for instance, would have to deal with the loss of her son. She might become more involved in the affairs of the demigod world, trying to make sure that her son's sacrifice was not in vain. Also, his half - siblings, if any, would be affected. They could be inspired to step up and prove themselves worthy of Percy's sacrifice.
The other students at Hogwarts would also be affected. For example, Neville, who looks up to Harry. If Harry ignores everyone, Neville might feel lost. Ginny, who has a special connection with Harry, would be deeply hurt. And the teachers like Snape, who has a complex relationship with Harry, would also be impacted. Snape might be secretly glad at first, but then realize that Harry's isolation could be a sign of a bigger problem in the wizarding world.
Aside from Percy, Silena Beauregard from the Aphrodite cabin could be a key character if she's still alive in the fanfiction's timeline. She might be conflicted about the kidnapping since she has friends outside the cabin. And of course, Grover could be involved too. He would sense that Percy is in trouble and try to use his nature - related powers to track him down.
His best friend could be one of the main characters. They would likely be very concerned and play a big role in his recovery.
Grover would be a great addition. In an AU, he could be Percy's best friend who is always getting him into (and out of) trouble. For example, in a college AU, Grover could be the one who convinces Percy to join a wild fraternity. He could also provide some comic relief. Another good character is Thalia. In a superhero AU, she could be a powerful superheroine with lightning powers. She could be a mentor or a rival to Percy and Annabeth, depending on the plot.
