At first, Percy could be in shock. He can't believe that the gods, whom he has served and trusted, would betray him. But then, as the reality sinks in, he might become determined to get justice. He starts to plan his next moves carefully, using his wits and the skills he has learned over the years. He may also feel a sense of sadness and loneliness, as he realizes he is now on his own against the powerful gods.
Well, in many such fanfics, the gods might react with anger. They could seek revenge on the abuser. For example, Zeus might send a bolt of lightning to strike the place where the abuse took place as a sign of his wrath.
The gods might be outraged. They could see Percy as one of their own, especially since he has done so much for them. They might immediately seek to punish the abuser. For example, Zeus could send a bolt of lightning towards the person who abused Percy.
They might react with shock, as they may not have fully realized the extent of the danger Percy has faced. Some gods could be impressed by his survival and show newfound respect.
Well, some past gods might be amused. They'd see these modern interpretations of their stories and characters in the Percy Jackson fanfiction as a strange yet interesting new form of worship or at least attention. For example, Zeus might be a bit irked at some of the liberties taken with his character, but also secretly flattered that people are still so interested in him.
In this fanfiction, the gods' reactions could vary greatly. Some gods may see Percy as a valuable asset in the fight against Kronos and cheer him on from the sidelines. Others might be jealous of the attention Percy is getting or fear that his success could disrupt the balance of power among them. The gods could also be influenced by their past relationships with Kronos. Those who have a history of enmity with him would be more likely to support Percy wholeheartedly, while those with more ambiguous relationships might be more hesitant in their support.
Most of the gods would be confused at first. Hera might see it as an opportunity to manipulate the situation for her own ends. She could try to use Percy's new connection to Ares to create more chaos or to further her own plans. Poseidon would be very conflicted. On one hand, he has a connection to Percy as his son, but now Percy has this new link to Ares which could put Poseidon in a difficult position among the other gods.
Some gods might be neutral. They would be more concerned with how this event would disrupt the balance of power among the gods. They might try to negotiate or find a compromise to avoid further bloodshed and chaos in the world of the gods.
The gods' reactions would also depend on the political climate in Olympus at the time. If there was already tension between different factions, this incident could be the spark that ignites a larger conflict. For example, if the nature - loving gods were at odds with the more war - like gods, Percy's situation could be used as a tool. Artemis, being a powerful and independent goddess, would have to navigate through all these political undercurrents while trying to make amends for her mistake to Percy.
Athena, being the goddess of wisdom, might analyze the fanfiction. She could look at how the mortal writers understand the Greek mythology and use it to create new stories. She might be impressed by the intelligence and creativity of some of the fanfictions, or she might be critical of inaccuracies.
