The main character is Percy, no doubt. But other characters could include Grover, his satyr friend. Grover could be an accomplice in some of the pranks, using his nature - related abilities to help Percy. And of course, the gods. They are the central figures in the sense that they are the ones being pranked. There might also be some minor gods or demigods who get caught up in the chaos that Percy's pranks create.
Percy is the key character in this fanfiction. He has the courage and the mischievous streak to prank the gods. Among the gods, we can expect to see Hermes, the god of trickery. Hermes might have a bit of a love - hate relationship with Percy's pranks. On one hand, he might admire Percy's cleverness, but on the other hand, he doesn't want the order of Olympus to be completely disrupted. And then there are the other demigods at Camp Half - Blood who might be witnesses or even unknowing participants in Percy's pranks.
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.
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.
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.
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.
The main character is Naruto for sure. When it comes to the Anbu, there could be some new and original Anbu characters created just for this fanfiction. They could have unique abilities and personalities. Naruto's relationship with these made - up Anbu characters could be really interesting. He might prank them in ways that play off of their individual quirks. For example, if one Anbu is really proud of his speed, Naruto could set up a prank that makes it seem like he's much slower than he thinks.
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.
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.
Obviously, Danny Phantom is one of the main characters as the title implies he's the one doing the pranking. And then, members of the Justice League like Superman, Batman, Wonder Woman, Flash, etc. would be the ones being pranked.
Odin is very likely to be in Percy's fanfiction. His wisdom and his role as the all - seeing god could make for some interesting plot points. Thor is also a mainstay, with his superhuman strength and his connection to thunder. Loki is another one. His mischievous nature could create all kinds of trouble and twists in the story. He could be an antagonist or an unexpected ally to Percy.
