One possible plotline could be that Naruto and Athena have to unite their two worlds against a common enemy. For example, an ancient evil that threatens both the ninja villages in Naruto's world and the realm that Athena protects in Greek mythology. They would use their combined skills, Naruto's Rasengan and Athena's strategic planning, to lead their people in the fight.
Yes, it can be quite popular in certain fan communities. The idea of crossing over two very different characters like Naruto from the Naruto universe and Athena, who has roots in Greek mythology, creates a unique and interesting concept. Fans enjoy exploring how their different powers, personalities, and backstories would interact in a married relationship. It allows for a lot of creative freedom in writing fanfiction, such as imagining how Naruto's ninja skills would mesh with Athena's wisdom and strategic abilities. Some might write about them facing challenges together in a new world that combines elements of both their original settings.
If Poseidon and Athena were married in fanfiction, it would likely cause a great stir in the pantheon. Other gods would be either envious or worried. Envious because they might see their union as a powerful combination. Worried because it could mean a shift in power dynamics. For instance, Poseidon and Athena together could influence Zeus's decisions more strongly.
In a fanfiction where Poseidon and Athena are married, their relationship could be filled with power struggles. Both are strong deities. Poseidon, the god of the sea, is often impulsive and passionate. Athena, the goddess of wisdom, is more rational. Their marriage might be a union of different natures. They could constantly be trying to outwit each other in a friendly way, with Poseidon using his brute strength and Athena her intellect. For example, when it comes to matters of ruling over certain territories, Poseidon might want to claim it by force, while Athena would come up with a more diplomatic solution.
It could be a very unique married life. Ares might bring his passion and energy into their relationship, while Athena would use her wisdom to manage their affairs. They could be a powerful couple, with Ares protecting their domain physically and Athena making smart decisions for their future. They might also host grand feasts in Olympus where they showcase their combined influence, with Ares showing off his war trophies and Athena impressing the guests with her intellectual discussions.
One possible plot twist could be that the other gods oppose their union. Since Ares is the god of war and Athena is the goddess of wisdom, their marriage might disrupt the balance among the gods. The gods might fear that their combined powers would lead to unforeseen consequences. For example, Zeus could be worried that they would become too powerful and try to overthrow him. Another plot twist could be that there's a hidden prophecy related to their marriage. Maybe it was foretold that their union would either save or destroy the world of the gods. This would add a layer of mystery and danger to their relationship.
One possible plot twist could be that the gods oppose the marriage. Since Athena is a virgin goddess in Greek mythology, her getting married would go against the traditional view of the gods. This could lead to a conflict where Percy has to prove himself worthy not only to Athena but also to the other deities.
In a fanfiction, perhaps the gods' rules change. Maybe Athena, seeing Percy's courage and loyalty, decides to break the norms. It could start with them having to work together on a really important quest where they develop a deep bond. They might realize they share a common goal of protecting the world in a different way. This newfound understanding could lead to feelings growing between them, despite the initial oddity of a mortal and a goddess getting together.
For Percy's family, it would be a huge shock. His mother would probably be worried at first because Athena is a goddess. But then she might see how much Percy loves Athena and come to accept it. His friends like Grover would be in awe and might also be a bit jealous. As for Athena's side, the other gods would be divided. Some might see it as a new era of cooperation between gods and demigods, while others would be against it as it goes against the norms.
In these fanfictions, Percy often retains his bravery and loyalty. His more impulsive nature can create interesting dynamics with Athena's calculated wisdom. For example, he might rush into a situation while Athena is thinking of a strategic plan.
