Well, in this fanfiction, the plot could revolve around Percy having special powers given to him by Artemis. Maybe he can communicate with animals in a unique way that's different from the other demigods. And he has to use these powers to protect the natural world, which is very important to Artemis. There could also be a sub - plot where Percy discovers more about his real parents while living with Artemis, creating an interesting internal conflict for him.
One possible plot could be Percy struggling to fit into Artemis's group of hunters. Since he's male and the hunters are usually female, there would be a lot of conflict and misunderstanding at first. He might have to prove himself worthy of being part of the group, not just because he's Artemis's adopted son. He could go on a quest to retrieve a sacred item for Artemis to show his loyalty.
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 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.
One idea could be Percy having to learn the ways of Artemis's hunters. He might struggle with the no - male - contact rule at first but then find unique ways to bond with his new sisters. Another could be Percy going on a quest specifically related to Artemis's domain, like protecting a sacred forest. And he could use his water powers in new and unexpected ways in the context of Artemis - related tasks.
The Titans could still be antagonists. Even though Percy is now associated with Artemis, the Titans might see him as a threat or a tool to use against the gods. Kronos, for example, could try to turn Percy to his side by offering him power or by threatening those he cares about in Artemis's group.
Well, it could be about Percy having to deal with the conflict of being the son of two such different deities. Maybe he has powers from both Orion and Artemis. For example, he could have Orion's hunting skills combined with Artemis's connection to the moon. He might struggle to fit in with the normal demigods as his origin is so unique.
The plot could involve the son of Artemis facing abuse from other demigods who are jealous of his unique parentage. He might struggle to find his place in the Camp Half - Blood, constantly facing discrimination and harm. Then, perhaps Percy Jackson could come to his aid and together they try to expose the bullies and change the situation at the camp.
The plot could involve Percy trying to find his place in the demigod world. Since Artemis doesn't usually have children, Percy would be an anomaly. He could be on a quest to discover more about his mother and his own identity. Maybe he has to prove himself to the other gods and demigods that he is worthy despite his strange origin.
One possible plot could be Percy finding out he's the son of Artemis in a very unexpected way. Maybe he has some powers related to the moon that start to manifest. He could be shunned by the other demigods at first because it's so unheard of for Artemis to have a son. Then he goes on a journey to find out more about his mother and his place in the demigod world.
A possible plot could be that Percy is initially unaware of his true parentage. He grows up with normal demigod problems, but strange things start to happen. He has an unusual affinity for the moon and animals, which are associated with Artemis. As he discovers the truth, he is caught in the middle of a power struggle between the gods. Some gods want to use him for their own purposes, while others want to destroy him. Percy has to fight to survive, make allies, and figure out his place in this new and dangerous world. He also has to deal with his feelings towards Artemis, who is not like a typical mother figure.
Well, it could be about the son having unique powers. Since Percy has control over water and Artemis is a powerful goddess, the son might have some sort of combination like the ability to control water in a lunar - influenced way. Maybe he can create ice sculptures during a full moon or something.
