Well, if Percy is raised by Apollo, he could be trained in the arts of prophecy as well. This would give him an edge in anticipating future threats. Maybe he would be more in tune with the sun's power, and could use it to boost his strength during battles, much like how Percy already uses water powers but with a solar twist.
The plot could be centered around Percy's identity crisis. Since he's raised by Apollo, he might struggle with whether he should follow Apollo's more flamboyant and carefree ways or stay true to his own nature. He could be exposed to Apollo's many lovers and children, which would make him question his place in this complex family. Additionally, his relationship with other demigods would change. He might be seen as an outcast by some who are loyal to Poseidon, while others might be jealous of his connection to Apollo. This would lead to various adventures where he has to prove himself not just as a son of Poseidon but as someone with a unique upbringing under Apollo.
It could be about Percy having some sort of traumatic experience that leaves him scarred, and Apollo takes him in to raise him. Maybe Percy's experience was related to a battle or some sort of mythical encounter, and Apollo, seeing Percy's potential or just out of kindness, decides to be his guardian.
Percy would likely become more confident in his abilities. Apollo's influence would make him more outgoing and perhaps a bit more self - assured. He'd also probably have a greater appreciation for beauty and the finer things in life.
In this fanfiction, Percy's identity could be somewhat transformed. He may take on some of Apollo's traits. Maybe he becomes more confident in his appearance and charm, like Apollo. His combat style could also change. Instead of just relying on his swordsmanship and water powers, he could incorporate Apollo's archery skills. He would have to learn how to make and use arrows, and this new skill would make him a more versatile fighter. His relationship with other characters would shift too. Some might be jealous of his new connection with Apollo, while others would be curious about how he has changed.
His character would become more confident in his artistic abilities. Apollo is the god of many arts, so Percy would likely be exposed to music, poetry, and painting. He might be more flamboyant in his actions and speech, as Apollo has a certain charm. For example, he could start using more flowery language when talking to his friends or enemies.
Perhaps Percy would have a more strained relationship with the other gods. Since Hera is not the most popular among the gods, those who oppose her might be less inclined to help Percy. He would also likely have a very different relationship with Zeus. With Hera as his mother figure, Zeus might be more watchful and even more distrustful of Percy, fearing that Hera has some ulterior motive in raising him.

One possible plot could be that Percy, being raised by Artemis, grows up with a deep connection to nature and the moon. He might be trained in archery and hunting from a young age. Since Artemis is a virgin goddess, Percy would have to deal with the unique situation of being part of her all - female group, perhaps facing some initial resistance from the hunters. He could also develop special powers related to the moon or gain an enhanced sense of stealth.
Percy would probably be angry at first. He has a strong sense of justice and being kidnapped against his will would make him fight back. He might immediately try to use his water powers to break free or at least create a distraction.
Well, perhaps Percy is being trained in some sort of combat or special skills by Apollo. Maybe Apollo is teaching him archery, which is Apollo's specialty. Percy could be learning to use a bow and arrow in new and creative ways to defeat his enemies.
