Well, it depends on the specific fanfiction. There are countless fanfictions out there, and some authors might choose to reimagine Percy Jackson as a demon for the sake of a unique and edgy story. But the traditional view of Percy is that of a demigod with his own set of powers and adventures that have nothing to do with being a demon.
He would become more cynical. His once - positive view of the world and people would be replaced with suspicion and hatred. He might start to see everyone as an enemy.
His relationship with Annabeth would be really interesting. At first, Annabeth might be shocked and a bit unsure how to act. But they could also develop a deeper understanding of each other as Percy now experiences things as a girl. With his male friends, like Grover, there could be some awkwardness, but also a chance for them to see Percy in a new light and strengthen their bond in different ways.
Well, one possible plot could be that Hestia has some grand plan. Maybe she turns Percy into a girl to teach him a lesson about seeing things from a different perspective. For example, he might face different challenges as a girl in the world of the story, like how people treat female characters differently in that fictional universe.
In the 'Percy Jackson turns into a cat' fanfiction, he could end up in some really interesting situations. For example, he might be chased by some of the magical creatures at Camp Half - Blood that don't recognize him as Percy. His senses would be heightened as a cat, so he could detect things like danger or hidden treasures more easily. Also, it would be hilarious to see how Annabeth reacts when she first sees Percy as a cat. She might be confused at first but then try to figure out how to turn him back.
The fanfiction could explore Percy's transformation from a human - demigod perspective. As a pegasus, he might have different instincts and emotions. He could struggle with the loss of his human form at times, but also find great joy in the freedom of flight. There could be a plot where he has to use his pegasus form to save his friends or the camp. Maybe he discovers a hidden power within his pegasus self that is unique and helps him in a crucial battle against an ancient enemy.
My knowledge doesn't have anything related to the main character becoming a demon king. Can you provide me with more relevant information so that I can better answer your questions?
His relationship with Annabeth would be different. She might have to get used to Percy being a pegasus. There could be some initial awkwardness, but also a deeper understanding as she sees him in a new form.
One main plot twist could be that the person who betrays Percy is someone he least expects, like a close friend or family member. This shatters his world and makes him question all his relationships, leading him to turn evil as he feels he can't trust anyone anymore.
His decision might give hope to other demigods. They see that it's possible to be content without striving for godhood. For example, some demigods who might have been jealous or envious of Percy could now see that there are other paths to a fulfilling life.
