They might see mortals as more creative. Since fanfiction often involves unique interpretations and new storylines, the gods would realize that mortals can come up with some very interesting ideas about them.
They may start to understand mortals' fascination with them better. By reading the fanfiction, they can get a sense of why mortals are so interested in their stories, their powers, and their relationships. This could lead to a more positive view of mortals in general, as they realize that mortals are not just simple beings but have a deep appreciation for the gods' world.
Their view could become more complex. If they see in the fanfiction how mortals imagine their powers and personalities, they might realize how much mortals are intrigued by them. Some gods might start to respect mortals more for their creativity in writing these stories. Others might become more disdainful, seeing how mortals sometimes distort their true natures in the fanfiction.
They might think mortals are more creative. The fanfiction shows that mortals can come up with all sorts of wild ideas about the gods, which could make the gods see mortals as having vivid imaginations.
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.
If the Olympians read The Lost Hero fanfiction, their view of mortals could change in multiple ways. Poseidon might develop a newfound respect for mortals' imagination. He could see that mortals can come up with interesting twists and turns in the stories related to the gods. Hera, though, might become more disdainful. She might think mortals are meddling in things they don't understand and are distorting the true nature of the Olympians. Apollo, on the other hand, could start to view mortals as potential collaborators in the world of storytelling, given his own love for stories and poetry.
Percy's relationship with the other demigods could change significantly. He could become a sort of mediator between the demigods and the father of the gods. This new role might earn him respect from some, but also envy from others who think he's getting special treatment. He might also have to make tough decisions that could affect the demigod community as a whole, which could further impact his relationships.
If the gods read the fanfiction, they could view the Battle of Manhattan in a more human - centered way. The fanfiction might focus on the individual experiences of the participants, which could make the gods more empathetic towards the humans involved. They could also see how the battle has been mythologized in human culture through the fanfiction.
The power structure would be completely disrupted. There would be no more divine interference in mortal affairs, which could lead to chaos at first as there are no gods to control natural elements like the sea or the sky. But it could also lead to new opportunities for mortals to take control of their own destinies.
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.
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.
If the gods read the fanfiction, Percy's story could take a meta - turn. He might become aware that the gods know about this fictional version of him. This self - awareness could lead to his character development in unexpected ways. He could either strive to live up to the fanfiction's portrayal or try to distance himself from it, both of which would change the course of his story significantly.
