The main character is Percy. In relation to his status as a middle child, his parents also become important characters in the fanfiction. Their parenting style and the attention (or lack of it) they give to Percy compared to his siblings can be a major plot point. And then there are his peers at school or in the neighborhood. Some of them might be friends who stand by Percy, while others could be rivals. All these characters together create the world of the percy the middle child fanfiction.
In many 'child of pan percy jackson fanfiction', Chiron, the centaur, can be an important character. He is very knowledgeable about the demigod world and can offer guidance to the child of Pan. Additionally, there could be new characters created specifically for the fanfiction, like a mysterious nymph who has a special connection to the child of Pan and helps them uncover their true destiny within the world of Percy Jackson.
Obviously, Percy Jackson would be one of the main characters since it's about him being the true child of chaos. There might also be other characters from the original Percy Jackson series like Annabeth Chase, who could play an important role in his journey as his girlfriend and a smart strategist. Grover Underwood might also be there as Percy's friend and protector.
Percy is the central figure, no doubt. But also, there could be other characters like Grover. Grover would be in a difficult position as Percy's friend. He would want to support Percy but also be cautious because of Percy's connection to Kronos. Additionally, some new characters might be introduced, perhaps other children of Kronos or characters from Kronos' past who have a role to play in Percy's story.
Since it's a Percy - centered fanfic, Percy is surely one of the main characters. There may also be other characters from the Percy Jackson series like Annabeth, Grover, etc. who could be involved in the story to react to Percy's new identity as a child of Chaos.
One interesting story could be Percy's struggle to find his own identity among his siblings. Since he's the middle child, he might feel overshadowed at times. In some fanfictions, he discovers a unique talent that sets him apart.
A new character could be a transfer student from another demigod camp. This student has a different set of powers and a unique backstory related to a less - known Greek god. They could initially clash with Percy but then become great friends as they face challenges together.
I'm not sure specifically since I don't know the exact fanfiction, but it could be his friends who might be either involved in his hacking activities or completely unaware of them. Maybe there's a mentor - like figure who guides him in the world of hacking.
The main characters are Percy and Piperlemon. Percy, who is often known for his demigod status and his adventures in the original series, is one of the main focuses. Piperlemon, on the other hand, is a character unique to this fanfiction. Their relationship and individual personalities drive the stories in this fan - made world. For example, Percy might use his skills to protect Piperlemon in some stories, or they might team up to achieve a common goal.
There could be other gods as well. For instance, Zeus might play a role, perhaps being suspicious of Percy's newfound godly powers or seeing him as a threat to his own authority. Hermes could also be there, acting as a messenger or a guide to Percy in the world of the gods.
Obviously, Percy is the main character. He is the focus of the story as it is about him in solitude.
