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.
Probably Poseidon. Since he's Percy's father, he has a natural inclination to help him. He might send some sea creatures to assist Percy during the fight or use his powers to give Percy an advantage in some way.
Poseidon would probably be one of the main gods watching. Since Percy is his son, he would have a strong interest in his well - being during the fight.
Well, in such a fanfiction, Percy might show extraordinary combat skills that would impress the gods. Maybe they would be secretly rooting for him or perhaps even interfering in the fight in some unexpected ways.
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.
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.
Probably Poseidon, as he is Percy's father and has a vested interest in his son's well - being. Zeus might also be protective in some cases, despite their past differences, as Percy is a hero who often saves the world which benefits Zeus's realm as well.
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.
Well, without reading the specific fanfiction, it's hard to say exactly who Percy is. But generally, in a 'champion of the gods' scenario, Percy would be a central figure. He might be a hero with unique powers, like being able to control certain elements or having superhuman strength. He could be a character who has to face various challenges and tasks on behalf of the gods, kind of like a chosen one in a fantasy story.
Percy's reaction could also be one of self - doubt. He may start to question his own actions and leadership. He might think that he has done something wrong to push Annabeth away. However, his loyalty to his friends and the cause would eventually make him stand up against Kronos and try to bring Annabeth back to the right side.
