A fanfiction like this could also explore Percy's character in a new light. He's known for his courage and loyalty, but being married to Gaia would test him in ways he's never been tested before. He might have to make some tough choices, like sacrificing some of his own power or even his relationships with his friends to fight against Gaia. And it could also introduce new characters or creatures that are related to Gaia's realm. Maybe there are some ancient earth spirits that Percy has to deal with, and he has to learn new ways to use his powers to interact with them.
One idea could be that Percy has to find a way to break the strange bond that makes him Gaia's 'husband' in the fanfiction world. Maybe he discovers some ancient prophecy that gives him a clue on how to sever this unholy connection.
A big part of the fanfiction could be about the reactions of the other characters. The other demigods would be shocked, and the gods would probably have mixed feelings. Some might see it as an opportunity to gain power through their connection, while others would be envious. And Percy and Aphrodite would have to navigate their relationship while dealing with all these outside forces.
A fanfiction like this would likely explore Percy's new role in a world where he is the father of Athena. It could show how he imparts his own values and skills to her. There might be adventures where they work together, and Percy has to protect Athena as she grows up. It would also need to explain how this new family dynamic affects the rest of the demigod world and the relationships between the different cabins at Camp Half - Blood.
The fanfiction might explore how Percy's relationship with other characters changes. For instance, he may have to face the judgment of Athena, Annabeth's mother, as he takes on the role of father. Athena could be skeptical or even hostile at first, but over time, Percy could prove himself worthy. Also, Percy would have to interact differently with his own friends and family, like his mother Sally, who might now be a grandmother - like figure to Annabeth.
If Percy was the son of Gaia and Tartarus in fanfiction, his power set would be a fascinating blend. From Gaia, he could potentially have the power of terraforming, reshaping the earth on a large scale. He might also be able to communicate with all forms of earth - bound life. From Tartarus, he could gain the ability to traverse the darkest depths of the underworld with ease, and perhaps even draw power from the primordial chaos there. This would make him a very different and much more complex character compared to his original form in the official series.
One great 'Percy Jackson and Gaia' fanfiction is 'The Battle Against Gaia's Wrath'. It has an interesting plot where Percy has to gather new allies to face Gaia in a more strategic way than in the original series. The character development is really well - done too.
One aspect of 'Percy Jackson x Gaia Fanfiction' could be the unique power dynamics. Percy has his own set of powers from being a demigod, and Gaia is an extremely powerful primordial goddess. Their interaction in fanfiction might explore how Percy, with his courage and skills, contends with Gaia's all - encompassing power. It could also delve into the moral and ethical implications of Percy's relationship with such a powerful and ancient being.
He would likely be more in tune with the earth and the sky elements. His powers might not just be limited to water control as before. For instance, he could have the ability to manipulate the ground like Gaia's children and also have some control over the air or weather like related to Ouranos.
In most traditional Percy Jackson lore, he is the son of Poseidon. However, in fanfiction, authors can create all kinds of alternate universes. So, it's possible for him to be depicted as the son of Gaia and Tartarus in some fan - created stories.
One creative idea is a time - travel fanfiction where Percy travels back in time to before Gaia was fully awakened. He tries to prevent her awakening in a completely different way than what was shown in the original series. Maybe by influencing the actions of minor characters from that era.
