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.
In this fanfiction, Percy is the central figure. But among the gods, we might see Hades as well. Given Percy's connection to the underworld through his father Poseidon. And Aphrodite could be there to stir up some drama, perhaps using her powers of love to create some interesting situations for Percy. Grover, Percy's satyr friend, could also be involved, adding his own brand of humor and loyalty to the story.
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.
Obviously, Percy would be one of the main characters. And then there's Chaos. Depending on the writer, other characters from Percy's world like Annabeth or Grover might also make an appearance, perhaps coming to find Percy in the chaos - filled realm.
Obviously, Percy and Poseidon are the main characters. Percy, the young demigod with his courage and powers, and Poseidon, the powerful god of the sea.
Percy is bound to be central. Alongside him, some new characters could be introduced. Maybe there are demigods who are against Percy's return because they see him as a threat to their own status. But the main gods would still be major players. They could be portrayed in different lights, some being more desperate to get Percy back than others, which could lead to interesting power struggles among them.
Obviously, Percy would be the main character. His character would be very different from the original as his age gives him a whole new perspective.
In this fanfiction, Percy Jackson is bound to be one of the central characters. Then, we might see Hazel Levesque from the Roman camp. She has her own unique powers and backstory that could interact interestingly with Percy. Another likely main character could be Frank Zhang. His shape - shifting abilities and his role in the Roman camp could create some great storylines when combined with Percy's presence.
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.
The bullies themselves would be key characters. They could be the typical mean kids in Percy's school or wherever the story is set.
