In some fanfics, their relationship is one of mutual growth. Percy's experiences on the surface world teach Poseidon about the value of human qualities like courage and loyalty in a more personal way. Meanwhile, Poseidon's godly knowledge and power help Percy become a stronger and more capable demigod, forging a deeper bond between them as they both learn from each other.
The relationship can also be shown as very loving. Poseidon might secretly watch over Percy and be proud of his son's achievements. He could send signs of his support during Percy's battles or quests. And Percy, in turn, is always eager to make his father proud and show that he is a worthy son of Poseidon.
The relationship could be shown as a curious one. Since Percy is a baby, he might not fully understand who Poseidon is, but there could be an instinctual bond. Poseidon, on the other hand, could be filled with a sense of wonder at this small version of his son, seeing all the potential in him. He might try to communicate with Percy in gentle, non - verbal ways, like sending small ripples of water to make Percy laugh.
Often, there are storylines where Percy and Poseidon have to work together to save the world. Maybe a primordial force is rising and only their combined powers of a demigod and a god can stop it. Also, some fanfics explore the family dynamic between them, like Percy trying to understand his father more deeply, and Poseidon trying to be a better father despite his godly duties.
Another way is to portray it as a complex relationship filled with envy. Poseidon might envy Zeus's position as the king of the gods, while Zeus could be envious of Poseidon's power over the vast oceans. This envy could lead to various power struggles and tense moments between them in the fanfiction.
Poseidon might be presented as a rather powerless god in the context of Percy being abused in fanfic. Despite being Percy's father, he could be constrained by the will of Zeus and other gods, which prevents him from acting decisively to save Percy. Hades, however, might be a more interesting character. He may have his own motives for helping Percy. He could see Percy as a useful tool against the other Olympians or simply as a victim who he can relate to, given his own outcast status among the gods. So, in fanfic, he might play a key role in Percy's journey to overcome the abuse.
The fanfic could also explore how Poseidon's actions towards Percy affect Sally. For example, when Poseidon claims Percy as his son, Sally might have mixed feelings. On one hand, she's proud that Percy has a powerful father, but on the other hand, she's worried about the dangers that come with being a demi - god. This could create a complex dynamic between the three characters.
In some fanfictions, their relationship is one of deep mutual respect. Percy, as Poseidon's son, often seeks his father's guidance. Poseidon, in turn, tries to protect Percy from the many dangers in the demigod world while also teaching him about his powers.
The bond could be portrayed uniquely by having them communicate through dreams. Every time Percy dreams, he enters a special underwater realm where he can talk to Poseidon. They discuss things like the future of the sea, Percy's relationships with other demigods, and how to maintain peace between the gods and mortals. Through these dream conversations, their bond becomes something very special and different from normal father - son relationships in fanfiction.
In fanfiction, their relationship could be developed by having Poseidon be more involved in Percy's daily life. Instead of just popping in during big events, he could be there for the small things too. For instance, helping Percy with his schoolwork that involves marine biology. They could also have a project together like building a new safe haven for sea nymphs. Through this, they would bond over creating something positive. Also, Percy could start to take on some of Poseidon's responsibilities in the ocean, with Poseidon guiding him. This would not only strengthen their bond but also show Percy growing into his role as Poseidon's son.
Fanfictions may also depict their bonding in the context of quests. Poseidon could be subtly helping Percy from afar during his adventures. He might send sea creatures to assist Percy or give him signs in the form of ocean - related phenomena. This kind of silent support shows their connection, as Percy starts to trust that his father has his back, no matter what.
Their relationship could be shown as a sort of mentorship. Poseidon, as the all - powerful god of the sea, could be teaching Percy the more subtle and complex aspects of his powers. For example, how to control the tides in a way that is not just about brute force but also about finesse. This would make their relationship more than just a father - son bond but also one of teacher and student.
