One possible plot could be Percy discovering his new identity as the son of Demeter and struggling to adapt. He might have to learn new skills like controlling plant growth and communicating with nature spirits, all while still dealing with his normal demigod challenges.
A plot could involve Percy being sent on a special quest related to Demeter's domain. Maybe there's a blight on the crops in the mortal world that's being caused by a powerful monster, and Percy, with his new powers as the son of Demeter, has to find a way to stop it. Along the way, he could meet new characters related to the agricultural world and learn more about his mother's side of his heritage.
Maybe the plot is centered on a prophecy that involves the 'son of the moon'. This character could be the key to saving Camp Half - Blood from a new threat that is related to the moon's power being misused. So, they have to go on a quest, gather allies, and figure out how to use their own powers to stop the impending doom.
Another god could be the antagonist. For instance, Hades might be jealous of Demeter's newfound 'son' and the attention Percy is getting. He could send his minions to cause trouble for Percy or try to undermine Demeter's influence on Percy, leading to a series of battles and challenges for Percy to overcome.
One idea could be Percy exploring his new powers related to Demeter. Maybe he can control plant growth in unique ways, like making plants form protective barriers. Another could be his interactions with Demeter's other children. He might face some jealousy from them at first but then prove himself and form strong bonds.
Chiron is also likely to be a common character. He would be the one to help Percy adjust to his new identity as a son of Demeter. And there could be antagonists too. Maybe some monsters that are specifically targeting Demeter's children because of their connection to the earth and its resources. They could be trying to disrupt the balance that Demeter's children help maintain.
Yes, there are quite a few. You can check out platforms like Archive of Our Own (AO3). There, you'll find a variety of fan - created stories that explore the concept of Percy Jackson as the son of Demeter. Some might focus on his new powers related to nature and agriculture, while others could delve into how his relationship with the other demigods changes due to this new lineage.
One interesting plot could be Percy having to learn about Demeter's powers and how to use them in a unique way. For example, he might discover a new form of plant - based magic that only a son of Demeter could access. This could lead to him using plants to fight monsters in a really creative way, like making thorny vines trap foes.
The plot could revolve around Percy's relationship with his divine parents. Since Zeus and Hera have a complex relationship themselves, Percy might struggle with their expectations. Maybe he's caught in the middle of a power struggle between Zeus and Hera's different ideas of how he should use his powers. He could also be trying to unite the camps of different god - related demigods under his leadership as the son of two major gods.
One possibility could be that Percy, being the banished son of Odin, has to prove himself in the world of Percy Jackson. Maybe he has powers from Odin that are not fully understood in the demigod world. He could go on a journey to discover his true identity and find a way to regain his place. For example, he might face challenges from both the Norse and Greek mythological beings. He may have to use his wits and newfound powers to overcome these obstacles.
In 'The Traitorous Demeter', there's a major plot twist where Demeter seems to turn against Percy. This goes against the normal mother - son type relationship expected. It turns out she has been influenced by an ancient evil, and Percy has to find a way to break that influence and save her, while also dealing with the chaos it causes among the demigods.
A powerful nature - hating Titan who wants to plunge the world into eternal winter could be a great antagonist. He would be directly opposed to Demeter's power over the seasons and crops.
