Reading the fanfiction might make Percy more empathetic towards those in difficult situations. He already has a sense of justice in his own world, but seeing the struggles of the tributes in The Hunger Games could deepen his empathy. He could then be more likely to help those in need, not just in his own world of demigods, but also in any situation that resembles the oppression in The Hunger Games.
His view of power might change. In The Hunger Games, the Capitol holds extreme power over the districts, which is different from the power dynamics in Percy's world. He might start to think more about how power can be misused and how the oppressed can fight back.
Percy could gain a new understanding of the power of storytelling. Seeing how fans can take his world and create new and exciting tales might make him appreciate the stories of the Greek gods more. He might also start to see his own story as part of a larger tapestry that can be woven in countless ways by different people, which could give him a more inclusive and open - minded view of his own place in the world.
He might be quite intrigued. Percy has his own set of adventures in his world, and reading about Katniss and the Hunger Games universe through fanfiction would expose him to a whole new kind of dystopian adventure. He could compare the challenges Katniss faces in the arena to his own battles against monsters.
His view would be severely disrupted. President Snow has a very specific view of the Hunger Games as a means of suppressing the districts and maintaining his power. Fanfiction could present scenarios where the Games are not as effective in that regard. It could show the tributes having more agency or the Capitol being more corrupt than he wants people to believe. This would make him see the Hunger Games not as the powerful symbol of control he thought it was, but rather as something that can be easily subverted in the minds of the people, and he would do everything in his power to stop this new perception from spreading.
His view of friendship could expand. In Naruto, friendship is very strong and characters are willing to sacrifice a great deal for their friends. Percy might see new ways to show loyalty to his own friends.
His view of himself might become more complex. If he reads fanfictions where he is depicted as a super - powerful hero beyond what he already is, he could start to question his own limits. Or if he reads ones where he fails a lot, it might make him more self - critical.
It could also strengthen his bond with his friends. Realizing that others are interested in their story and are creating their own versions of their relationships could make Percy feel closer to his friends. He might even share some of the interesting fanfiction ideas with them and have a good laugh together.
Well, Percy's skills as a demigod would give him a huge advantage. He could use his water - related powers to manipulate any water sources in the arena, like creating floods to drown opponents or using water to shield himself. Maybe he'd form alliances with other tributes who recognize his power, and together they'd take on the Capitol's cruel games.
It could make them more aware of how mortals misunderstand them. In fanfiction, there could be inaccuracies about the Titans. This might annoy some Titans, but it could also make them realize that mortals don't have the complete picture. So they may become more interested in clarifying their true nature to mortals if they ever interacted with the mortal world again.
Some fanfictions might explore what would happen if Percy Jackson had to participate in the Hunger Games. He has his demigod powers, so it would be an interesting take on how he would use them to survive in the arena. Maybe he could control the water sources in the arena or use his sword - fighting skills against the other tributes. And there could be stories where the Capitol in 'Hunger Games' tries to capture the demigods from 'Percy Jackson' to use in their games.
One interesting crossover could be the characters from Percy Jackson finding themselves in the arena of the Hunger Games. Maybe Percy uses his water - controlling abilities to create a water source in a dry arena, which would completely change the game dynamics.
