Percy as the son of Oceanus might be more aloof. Since Oceanus is a primordial god, Percy could inherit a sense of distance from the more common demigod affairs. He might be more focused on the grander scale of the ocean's well - being rather than the day - to - day problems of the demigod camp.
On the other hand, Percy could be more powerful and confident. Knowing his heritage as the son of a powerful ocean deity would give him a boost in self - assurance. He would likely take on challenges with more bravado and be less hesitant in the face of danger compared to a demigod with a less prestigious parentage.
Percy as the son of Vulcan would likely be more analytical. In the original, he was quite impulsive. But now, with Vulcan's influence, he might think more before acting. For example, instead of immediately jumping into a fight, he would assess the situation and figure out the best way to use his new powers, like creating a strategic weapon on the spot. He could also be more introverted as he delves deeper into his new abilities and the mysteries of his new heritage. He may spend more time alone in Vulcan's forges, tinkering and thinking, rather than being out with his friends all the time.
In addition to his water - based powers, Percy as the son of Hera and Poseidon could have enhanced leadership abilities. Hera is often associated with ruling and leadership. So, he might be able to inspire and lead groups more effectively. He could also have a stronger connection to the sky, as Hera has some associations with the heavens. This could give him the ability to control weather elements related to the sky, in addition to his control over water.
Canon Percy has powers related to water as Poseidon's son. If he were Artemis' son in fanfiction, his powers would likely be more lunar - based. He might be able to control moonlight, for example. He could use it to blind enemies or create illusions. Also, instead of being able to breathe underwater, he could perhaps run at super - fast speeds like the hunters do.
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.
In this fanfiction, Percy would likely have powers related to both Apollo and Athena. Canon Percy has water - based powers from Poseidon. But here, he might have the ability to heal like Apollo, which would be a huge difference. He could also have enhanced intelligence and strategic thinking from Athena. So instead of just relying on his strength and water powers in battles, he could use his wits and healing abilities as well.
His powers would likely be a blend of Kronos' and Rhea's. Kronos was associated with time, so Percy might have some control over time. He could slow it down or speed it up in a small area. Rhea was a mother goddess, so Percy might have a strong connection to nature and the ability to heal. This is different from his original powers as Poseidon's son where he mainly had control over water and could communicate with sea creatures.
If Percy is the brother of Artemis and Apollo, his personality might be more refined. Since Artemis is associated with grace and Apollo with beauty and culture, Percy could be more sophisticated in his mannerisms compared to the original Percy. He might be more attuned to the arts and have a deeper sense of propriety.
Canon Percy is mainly influenced by Poseidon, which gives him a certain set of traits like being loyal and having a connection to the sea. But if Percy was the son of Ares and Aphrodite, his personality would be a wild mix. He'd likely be more aggressive like Ares, quick to anger in some situations. However, Aphrodite's influence would also make him more charming and aware of social dynamics. He might be more concerned with appearances and how others perceive him compared to canon Percy.
Percy's personality would probably be more solitary at first. Growing up with wolves, he's used to relying on himself and his pack. So when he enters the world of demigods, he might have trouble trusting others immediately. He'd be more in tune with his instincts, which could make him seem unpredictable to those who don't understand his background. For example, he might follow his nose or gut feeling more often than following the advice of others.
There could be a power - hungry sea witch who wants to use Percy's connection to Oceanus for her own gain. If Percy refuses, she becomes an antagonist. Additionally, some of the more traditionalist sea tribes might view Percy as an outsider and try to drive him out, acting as antagonists in the story.
