The main character is Percy Jackson. Other characters could include Tyson, Percy's cyclops half - brother. Tyson could come to the school and help Percy with any underwater - related issues, like if there was a problem with the school's plumbing that was actually caused by a water - based monster. And there could be a group of students who form a sort of 'Percy Jackson fan club' within the school, always eager to hear his next adventure story.
The fanfiction could start with Percy reluctantly taking on a teaching job at Goode. He tries to keep his demigod identity a secret at first. But then strange things start happening at the school, like students having prophetic dreams or unexplained disappearances. Percy realizes he has to use his knowledge and powers to solve these mysteries and also teach his students about the hidden world of gods and monsters. He might even bring in some of his friends from Camp Half - Blood to help out.
In this fanfiction, apart from Percy, we could see his friends from Camp Half - Blood like Tyson. Also, some of the teachers at Goode who might have a more significant role this time. There could be new demigods that Percy meets at Goode. And don't forget the gods or goddesses who might interfere in Percy's life at Goode in some way, for example, Poseidon could give Percy some kind of sign or power boost when he is facing a difficult situation at school.
The school principal could also be an interesting antagonist. Imagine if he or she has somehow been influenced by a dark power from the mythological world. They start implementing strict and unfair rules at the school that target the demigods specifically, and Percy has to figure out a way to break the influence without getting expelled.
There could be a new bully at Goode who targets Percy because he senses Percy is different. This bully might turn out to have some connection to the mythological world, like being a descendant of a minor god.
In the 'Percy Jackson returns to Goode' fanfiction, it could be that Percy has to face some challenges related to his dual identity. On one hand, he is a normal student at Goode, on the other, he is a demigod. This could lead to some interesting situations where he has to balance between the two worlds. For example, he might have to hide his demigod skills during a school competition but still manage to win in a rather unexpected way. Also, there could be new characters introduced, perhaps a new demigod who also attends Goode and Percy has to team up with them to face a common threat.
In this fanfiction, perhaps Percy will make new friends at Goode who end up getting involved in his demigod world. There could be a plot where the school is in danger, and Percy has to use his powers and knowledge of the mythological world to protect it. Maybe he'll also have some interesting interactions with his teachers who suspect there's something different about him.
The main characters are Percy and Annabeth. Percy is a demigod, son of Poseidon, with the ability to control water. Annabeth is also a demigod, daughter of Athena, known for her intelligence and strategic thinking.
He could interact with his old friends at Goode, like Rachel. She has a special connection to the demigod world, and their relationship could be further explored. Also, there might be new teachers or students that Percy meets. Maybe a new student who is actually a demigod in hiding too, and they start to figure out each other's secrets.
Well, in the Percy Jackson books, there's no mention of Percy Jackson Goode reading Percy fanfiction. Fanfiction is more of an outside - the - official - story thing created by fans. It's not really part of the main plot or something the characters would typically be involved in. So, it's very likely that he doesn't read it.
For sure Percy. A merman who is an outcast among his own kind because he has a unique ability that others are jealous of. And Nico di Angelo could be another main character. Nico's connection to the underworld might play an interesting role when dealing with the merman's world which is so different from the underworld but still has some similarities in terms of being a hidden and often misunderstood realm.
