There is definitely some out there. One aspect that might be interesting in these fanfictions is how Percy's powers could be different since his parentage is from Zeus and Hera. In many traditional stories, Percy is a son of Poseidon, but in these fanfictions, he could have lightning - based powers or other abilities related to Zeus and Hera's domains.
One common theme is the struggle for identity. Percy, who is usually associated with Poseidon, now has to come to terms with being the son of Zeus and Hera. Another theme could be power - how he manages and discovers his new powers.
A great plot could revolve around Percy's role in the power dynamics among the gods. As the son of Hera and Poseidon, he has the potential to shift the balance. Some gods might try to use him as a pawn, while others see him as a threat. Percy would then have to navigate this complex political situation among the gods while also dealing with his own personal growth and the challenges that come with being a demigod.
A great storyline would be Percy going on a quest to find out more about his mother Hera. Along the way, he could encounter various mythical creatures and gods who either help or hinder him. Maybe he has to prove himself worthy of being Hera's son in the eyes of the other gods. He could also meet other demigods with similar situations and form a new group to face the challenges together.
Percy's powers would be more complex. He could have the ability to communicate with sea deities in a different way. Maybe he could use Hera's diplomatic skills to make deals with them or resolve disputes. His control over water could also be extended to other substances that have a connection to water, like steam or ice, in a more efficient way than before. And his powers of persuasion, which could be influenced by Hera, might be used to calm angry sea storms or make sea monsters cooperate with him, which is an interesting combination of his Poseidon - given powers and Hera - influenced skills.
Percy's relationship with the other campers at Camp Half - Blood would be a rollercoaster. The children of Poseidon might feel a bit betrayed or confused, as they thought Percy was one of their own. However, Percy could use his new status to bridge gaps between different cabins. For example, he could work with the children of Aphrodite to improve relationships in the camp, since Hera has some connection to love and relationships in a different way than Aphrodite. With the gods, his relationship with Zeus would be extremely strained, given Zeus's past issues with Hera. But he might find new allies among the gods who are friendly with Hera, like Hephaestus. Overall, Percy's relationships would be a mix of challenges and new opportunities.
Percy would likely become more regal and proud. Since Hera is associated with royalty, he might develop a more refined and authoritative personality. He could also become more calculating, as Hera is known for her scheming. For example, he might think more about long - term plans rather than just reacting impulsively like he used to.
One possible plot could be Percy discovering his new parentage of being the son of Zeus and Hera. He might struggle with the new identity as it goes against what he previously knew. For example, he could face challenges from the other demigods who are suspicious or jealous of his new status. He then has to prove himself worthy of this new heritage while also dealing with the complex politics among the gods.
One common trope is the outcast status. Since Hera is not the most liked among the gods in the Percy Jackson universe, her son is often made an outcast among the demigods. Another is the special powers. He might have some unique abilities related to Hera's domain, like control over family bonds or something similar.
Well, family drama is a big one. With Hera and Hades as his parents, there would be a lot of tension. Hera is often seen as a difficult goddess, and Hades has his own dark domain. Percy would have to deal with their different natures. Also, themes of acceptance among the demigods and gods would be common, as his new identity might not be easily accepted.
