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.
In a 'Percy Jackson Raised by Artemis' fanfiction, the story could start with Percy being orphaned at a young age and Artemis taking him in for some special reason. Maybe she saw his potential or a prophecy was involved. Percy would then grow up in the company of the hunters. He would be taught about the importance of purity in a different sense than what is usually taught at Camp Half - Blood. His adventures could include facing off against enemies that target Artemis' territory or the things she protects. And as he matures, he might have to make difficult choices between loyalty to Artemis and his own identity as a demigod with ties to Poseidon.
Percy's character would likely become more in tune with nature. He'd be more reserved perhaps, as he grows up in an all - female group. His sense of honor might be more shaped by Artemis' values, such as protecting the weak and the natural world.
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.
In such a fanfiction, perhaps the plot could involve Percy going on a great quest to prove himself worthy of Artemis. Maybe he has to overcome some ancient prophecy or defeat a powerful foe that threatens both their lives and the world. Along the way, they gradually develop feelings for each other that are initially unexpected due to Artemis' vow of chastity. But as they face numerous challenges together, they see each other in a new light and eventually decide to get married, uniting the powers of Poseidon and Artemis in a new way.
One possibility is that Percy grows up with a strong sense of independence and a connection to nature. Since Artemis is the goddess of the hunt, Percy might be trained in hunting and survival skills from a young age. He could also have a special bond with the animals in the forest, being able to communicate with them to some extent. This upbringing would likely make him a formidable fighter, not just with a sword but also with bows and arrows and stealthy combat techniques.
In this fanfiction, it could be that Artemis is in a situation where she is about to be killed or lose her powers forever. Percy, being the selfless hero he is, takes on a deadly task to prevent that from happening. Maybe it involves facing an ancient and malevolent god who has a vendetta against Artemis, and Percy uses his unique abilities and the element of surprise to try and stop this god, but at the cost of his own life.
One possible plot could be that the son of Artemis discovers a threat to the demigod world that is related to his mother's domain. He then seeks out Percy for help because of Percy's reputation. Together, they embark on a journey to find a magical artifact that can stop the threat.
In a 'Percy Jackson adopted by Artemis' fanfiction, perhaps Percy is exiled from Camp Half - Blood due to false accusations. Artemis, who has always been intrigued by Percy's courage, takes him in. With Artemis as his new guardian, Percy gets involved in the Hunters' battles against ancient monsters that threaten the world. He also has to deal with the jealousy of some of the other Hunters who are not happy about a male being in their midst.
One possible plot could be Percy having to defend Artemis from a new and powerful enemy. Maybe a primordial being has awakened and is targeting Artemis. Percy, with his skills and the help of his friends, must fight this enemy. He could also have to deal with the politics among the gods as he tries to protect Artemis, since some gods might not be so happy about his interference.
Well, it could involve Percy being tasked with protecting Artemis in a way that goes against his normal alliances. Maybe some dark force is after Artemis and Percy has to use his skills in a new and unexpected way.
In this scenario, Percy would be in a very tough situation. Artemis is a powerful goddess. Percy might have to use all his skills and the help of his friends. He could try to reason with Artemis first. Maybe he'd show her that he's not a threat to her or her hunters. If that doesn't work, he'd probably have to run and hide in places where her powers are limited. For example, in areas protected by other gods who don't want Artemis to overstep.
