Well, he might face new monsters. For example, some ancient and more powerful versions of the ones he's already fought. Maybe there are new quests waiting for him at the camp, like finding a lost artifact that has the power to either save or destroy the camp.
There could be a new camper who has some really unique powers. Maybe a child of a minor god that we haven't heard much about in the original series. This new character could be both a friend and a rival to Percy.
He might go on a solo adventure to discover more about his powers. He could encounter new mythical creatures that he hadn't seen around the camp. Maybe he'll meet some other demigods who are on the run or have their own secret quests.
One common theme is loyalty. In the Roman Camp, loyalty to the cohort and the camp as a whole is highly emphasized, and fanfictions often explore characters' loyalty being tested. Another theme is identity. Demigods in the Roman Camp may struggle with their dual identity as half - god and half - mortal. Power struggles are also common, as different demigods may vie for leadership or recognition within the camp.
The plot could involve Percy being abandoned by camp because the camp leaders fear his growing power. He wanders the world, feeling lost and angry. Percy then encounters a mysterious figure who offers him a way to get revenge on the camp. However, Percy, being a hero at heart, realizes that taking revenge won't solve anything. Instead, he decides to find evidence to clear his name and expose the real danger that the camp is ignoring while he was being pushed away.
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 kind of fanfiction, a common concept is Percy's role in the camp hierarchy. Since he's a 'god' now, he might be at the top, which could lead to jealousy or admiration from others. Also, the fanfiction might explore how Percy's training changes. Instead of the regular demigod training, he could be getting special training from the elder gods. And perhaps his quests are now on a grander scale, involving saving not just the camp, but the entire world of gods and mortals.
He could go to New York City. It has a lot of water sources like the Hudson River where he can use his powers. Also, there are many places to hide from monsters.
Well, in many fanfictions, Percy Jackson's class could get involved in a quest at the camp. Maybe they have to retrieve a lost artifact or solve a mystery that's been plaguing the camp. They could also form new friendships and rivalries with the other campers. There might be some intense training sessions where they learn to use their newfound powers. And who knows, they could even encounter some long - lost gods or goddesses who have a special task for them.
Definitely Hazel. She has this unique power over the Mist and her past from the 1940s is really fascinating. In fanfiction, she can be the center of stories that involve time - travel or dealing with ancient curses. Frank is also well - liked. His shape - shifting ability and his journey of self - discovery are great fodder for fanfiction. Writers can explore how he grows into his leadership role at Camp Jupiter. And of course, Percy himself when he's at Camp Jupiter. His fish - out - - water experience as a Greek in a Roman camp is always fun to read about in fanfiction.
