In fanfiction, Percy Jackson might be a demon to add an element of shock value. It grabs the reader's attention and makes the story stand out. Also, it could be a way to explore different mythologies or combine different supernatural concepts. For example, mixing Greek mythology (from which Percy originally comes) with demonology to create a unique and exciting story world. Sometimes, it's just the author's personal preference to experiment with the character in a completely different way.
One reason could be for a fresh take on the story. Writers might want to break away from the typical demigod narrative and explore a darker, more supernatural side of the Percy Jackson universe. Another reason could be to create a more complex and morally ambiguous character. By making him a demon, they can introduce new conflicts and relationships.
In fanfiction, Percy being rich might be a way for the writer to explore different aspects of the Percy Jackson universe. Maybe they want to show how the world of demigods would interact with wealth. It could also be a way to make Percy more like a modern hero, who often has access to a lot of resources. Plus, it can lead to comical situations where Percy, who is used to a more simple life, has to deal with the trappings of being rich, like dealing with butlers or managing a large estate.
Some fanfiction writers may do it to stand out. Since the Percy Jackson series is so well - known, creating a version where he is a devil can attract attention. Also, it could be a way to explore darker themes. The original series has a lot of heroic and positive elements, but in fanfiction, making Percy a devil allows for a look at the other side of the coin, like how his powers could be used for evil instead of good.
One possible reason could be power politics among the gods. Poseidon might see Percy as a liability in some complex power play. Maybe other gods are pressuring him to distance himself from Percy for some hidden agenda. Another reason could be a misunderstanding. Percy might have unknowingly done something that Poseidon misinterprets as a threat to his domain or power. For example, Percy's actions in the mortal world might have unintended consequences for the underwater realm.
Some authors might write it to add a new and unexpected twist to the Percy Jackson story. They may want to see how the other characters would react if such a thing happened. Also, it could be an attempt to explore the psychological impact on Percy in a very different and extreme situation, though this is a rather controversial approach.
In some fanfictions, Percy might be banished because he goes against the traditional ways of the demigod society too much. For example, if he tries to form an alliance with a group that the other demigods consider enemies. His actions could be seen as a threat to the stability of their world, so they banish him to keep the peace.
One reason could be to create a more powerful version of Percy. Fanfiction writers might want to see how he would fare in more extreme situations with super - soldier abilities added to his demigod powers. It's also a way to mix different fictional universes and concepts, making the story more unique.
There are several possible reasons. Firstly, for the sake of drama. It makes for a very intense and emotional story when a beloved character like Percy dies. Secondly, it could be to explore the after - effects on the other characters. How would Annabeth cope? How would the Camp Half - Blood react? Also, it might be a way to show the unforgiving nature of Tartarus.
In fanfiction, Percy could become a champion of Kronos due to a complex web of factors. It could start with his disillusionment with the Olympians. After all the battles he's fought for them, if he sees no real change in how they treat demigods or the world in general, he might be open to an alternative. Kronos, being a master manipulator in these alternate stories, could offer Percy power and a chance to truly make a difference. Also, Percy's relationships could play a role. If someone he trusts sides with Kronos and convinces him, or if he's in a situation where he has no other allies and Kronos offers support, he could end up in that role. But these are all departures from his original character in the official Percy Jackson series.
One possible reason could be a spell gone wrong. Maybe a magician or a god accidentally casts a spell that sends Percy back in time.
Well, in fanfiction, one reason could be the loss of his friends. Percy has been through so many battles, and if he loses someone close like Annabeth or Grover, it could send him into a deep depression. Another reason might be the burden of his prophecies. He's constantly expected to save the world, and that kind of pressure can wear a person down over time.
