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.
To create a well - rounded character for Percy, consider his powers. He could have control over lightning like Zeus, but also a connection to nature and the moon from Leto. These powers should come with limitations and a learning curve. For instance, at the start of the story, he might not be able to fully control his lightning powers and accidentally cause small disasters. As he grows and matures throughout the fanfiction, he learns to master his abilities and use them for good. Also, his relationships with other characters, such as his friends and rivals, should be complex and dynamic, adding depth to his character.
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.
Common themes include identity crisis. Percy has to figure out who he is now that his parentage has changed. There are also themes related to the Olympian hierarchy. With Zeus as his father, he might be thrust into a different position in the power structure. Additionally, themes of loyalty can come up. Who does he stay loyal to - his old friends and family or his new divine family? These themes make the fanfictions engaging and full of potential for complex storylines.
To write a compelling Percy, give him flaws. Maybe he's overly impulsive because of his divine heritage, which often gets him into trouble. Also, show his internal struggle with being the son of Zeus. He could be constantly torn between living up to his father's expectations and forging his own path.
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.
His powers might include the ability to control the weather like Zeus. So he could summon thunderstorms or clear skies at will. From Leto, he could inherit a connection to the moon. This might give him enhanced senses during the night or the ability to draw power from moonlight. He could also have some form of protection or blessing related to his mother's association with motherhood and fertility in mythology.
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.
In the fanfiction, Percy's relationship with Zeus may develop gradually. Zeus, being a powerful and often aloof figure, might initially be distant from Percy. But as Percy shows his courage and abilities, Zeus could start to take a closer interest. This might lead to Zeus mentoring Percy in some ways, teaching him about godly powers and responsibilities.
Percy would probably become more arrogant at first. But as he faces challenges related to his new identity, he'd learn humility. His loyalty to his friends might be tested as Zeus could demand things that conflict with his friends' interests. He'd also have to deal with the expectations of being the son of the king of the gods, which would shape his character in ways different from when he was just Poseidon's son.
Since Leto has her own history and experiences, Percy could become more empathetic towards the Titans. This newfound empathy could make him more diplomatic in his interactions with others. He might also become more of a loner, as Leto's adopted son, exploring the world on his own terms and trying to understand his new identity. This would shape his personality in a way that is both different from his original self and yet still retains some of his core traits like his sense of humor and determination.
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.
