One idea could be to write a fanfic where Percy uses his demigod powers to play a prank on Gabe Ugliano in a really creative way. For example, he could make it seem like all of Gabe's lottery tickets turn into worthless pieces of paper every time he touches them.
Gabe could be kidnapped by a group of mythical creatures who mistake him for someone important. Percy would then have to rescue him, not because he likes Gabe, but because he knows it's the right thing to do. Along the way, Percy could learn more about Gabe's past and why he is the way he is, which could lead to some unexpected character development for both of them.
There could be. Fanfiction writers sometimes take the existing characters and settings from a story like 'Percy Jackson' and explore different scenarios, including difficult ones like abuse. But it's also likely that this type of fanfiction might not be as common or widely promoted, given the heavy nature of the topic. You can try searching on fanfiction platforms, but be prepared for some potentially upsetting content.
The writer can use vivid descriptions of the home environment. For instance, showing a dirty and chaotic living space created by Gabe, which can give readers a sense of the oppressive atmosphere Percy endures.
It could be portrayed through Percy's internal thoughts. For example, we could see his constant fear and unease when Gabe is around. Every little action of Gabe, like slamming a door or raising his voice, could send shivers down Percy's spine, and these thoughts could be written out.
One interesting 'Percy Jackson Gabe' fanfic could be 'Gabe's Redemption'. It might explore the idea of Gabe changing his ways in a world full of Greek mythology elements. Another could be 'Percy vs Gabe: The Final Showdown' which could be filled with action-packed scenes as Percy finally confronts Gabe. And there's also 'Gabe in the Underworld' which might take Gabe on an unexpected journey through the Underworld.
Some fanfictions may detail the actual incidents of abuse more explicitly. Gabe could be shown stealing Percy's money, which is a form of financial abuse. There might also be descriptions of Gabe being verbally abusive, calling Percy names and putting him down. This abuse not only affects Percy's self - esteem but also shapes his view of the world outside of his home, making him more distrustful in general.
One possible plotline could be Percy struggling to hide the abuse from his friends at Camp Half - Blood while also dealing with his demigod duties. He might be constantly on edge, fearing Gabe's return or actions.
Well, Percy could experience emotional trauma. This might show up as nightmares or flashbacks in the fanfiction. He might also isolate himself from his friends and family because he feels ashamed or doesn't want to burden them with what he's been through. And his view of the world could become more cynical. He may start to see the world as a cruel place where bad things happen to good people like him.
