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.
In many fanfictions, Percy might use his water powers in a unique way. Maybe he combines his control over water with his sword fighting skills. He could create a giant water vortex to disorient Kronos and then strike with Riptide while Kronos is off - balance.
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.
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, 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.
Maybe there are some original characters created by the fanfiction author. These characters could have their own unique abilities and backstories. They might be the ones who tip the scales in Percy's favor, for instance, by having a special power that weakens Kronos just before Percy makes the final blow.
Luke could also be a prominent character. Since he has a complex relationship with Kronos in the original story, in fanfiction he could play a role in either helping or hindering fem Percy's efforts against Kronos. Nico di Angelo is another possibility. His powers over the dead could be useful in a fight against Kronos, and he might team up with fem Percy for that reason.
It's possible that the author of the fanfiction wanted to show Percy's growth and development in a more extreme way. So they wrote that Percy had an in - depth understanding of Kronos' weaknesses. He could then use this knowledge to quickly and easily take down Kronos. For example, he might know that a certain spell or attack would be particularly effective against Kronos, and he just exploited that weakness without hesitation.
It could be that Kronos believes Percy has some hidden potential that, when combined with his powers, would lead to a situation beneficial for Kronos. For example, Percy's strong connection to the sea could be used in a way that disrupts Poseidon's domain and the balance among the gods. Kronos, being the Titan of time and a master of long - term planning, might foresee a complex chain of events that would unfold if Percy had his powers.
