Athena might also be among those watching. She has an interest in heroes and their battles, and Percy's actions could potentially affect the balance of power among the demigods, which is something she would keep an eye on. Also, Zeus might be there, as he likes to oversee major events and Percy's fight could be significant enough to draw his attention.
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.
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.
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.
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.
The Norse gods could be involved too. Odin, with his all - seeing nature, would be a likely candidate to be watching. He might be looking for signs of great warriors or leaders among the 'Descendants' characters. Thor could also be there, interested in the physical battles and the strength of the characters. Loki might be the most mischievous observer, perhaps secretly causing some of the chaos in the 'Descendants' world just for his own amusement.
Aphrodite could also be one of the spying gods. Since she loves meddling in love affairs, and Percy and Annabeth's relationship is quite famous among the demigods. She might be spying to see how their relationship develops and perhaps add a little nudge here and there if she feels like it.
I think Poseidon is a must - he's Percy's father, after all. Then there's Zeus, who likes to be in control and would want to see this baby who could grow to be a significant force. Apollo might come just for the fun of it, being the god of many things including prophecy, he might have some insights. And Artemis, as the goddess of the hunt, could also be there to see what all the fuss is about regarding baby Percy.
Obviously, Percy would be one of the main characters. And of course, the gods would play important roles too. Gods like Zeus, Poseidon, and Athena are likely to be there. Percy's friends from the demigod world, like Annabeth, might also make appearances.
Obviously, Percy Jackson himself. He's the one doing the pranking. Then, there would probably be the gods like Zeus, Poseidon, and Athena who are the targets of his pranks. His friends like Annabeth might also be involved, either helping Percy with the pranks or trying to stop him when they think he's going too far.
Percy is the central figure for sure. The gods, like Hades, might be there too if the story involves issues related to the Underworld. Grover could also play a role. He is Percy's friend and might be there to support Percy when he yells at the gods, or his experiences with the gods could be part of what drives Percy to yell. Chiron, the centaur, could also be a character as he is a mentor to Percy and could have some influence on the situation.
Obviously, Percy is one of the main characters. And then there would be various gods like Zeus, Poseidon, Athena, etc. These gods play important roles in Percy's world and their interactions with him would be central to the story.
