What are the common themes in 'Percy Jackson, Son of Zeus and Leto' fanfiction?

Yes, there are quite a few interesting ones. You can start by looking on fanfiction platforms like Archive of Our Own. Some fanfics might explore Percy's relationship with his divine parents in unique ways, or perhaps put him in new and exciting adventures that are different from the original series.

When writing Percy, think about his backstory. He grew up knowing his divine heritage, which could have both positive and negative impacts. He might have been bullied by other demigods out of jealousy, so he has a bit of a guarded side. But he also has a strong sense of justice, inherited from Zeus, which makes him always ready to stand up for the weak. His relationship with his parents should also be explored. He could have a closer bond with Leto as she was more present in his life, while Zeus was often distant due to his many responsibilities in Olympus.

Another idea is a story where Percy discovers a hidden prophecy related to his birth. In this fanfiction, he might have to team up with some unlikely allies, like a group of minor gods who are also interested in the outcome of the prophecy. The story could involve Percy learning more about his parents' relationship and how it has shaped his own destiny.

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.

One possible plot could be Percy's journey to discover his true place among the demigods. Since he is the son of Leto and Zeus, he might face unique challenges. For example, he could be caught in the middle of power struggles between different camps of demigods. He may also have to deal with the expectations and rivalries that come with having such powerful parents. His powers, which could be a combination of those associated with Leto and Zeus, might make him a target or a valuable ally.

One idea could be Percy having to mediate between Zeus and Hades during a major feud. Since he's the son of both in this fanfiction, he has a unique connection to them. He could use his powers and his knowledge of both of their domains to try and broker peace.

One common theme is identity. Since Percy is suddenly the son of Zeus, he has to figure out who he really is. Another theme is power. With Zeus as his father, he may have new and greater powers to control.

The Titans could be great antagonists. Since they often oppose the gods, they might see Percy as a threat, especially if he is the son of Leto. Kronos, for example, could try to stop Percy from fulfilling any prophecies related to Leto or the gods in general.

One idea could be Percy having to team up with Leto's other children in a quest to retrieve a powerful artifact that was stolen from their mother. Another could be Percy discovering a hidden connection between his powers and Leto's domain, leading to a new level of his abilities.

Well, it could involve Percy having to adapt to a new family dynamic under Leto. He might learn new powers or abilities related to Leto's divine nature. Maybe he'd have to deal with Leto's other children, if any in this fanfic, and face new challenges that come with being part of her family.
