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 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.
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.
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.
Well, one possible plot could be Percy discovering new powers. Since Hecate is the goddess of magic, Percy might learn magical abilities he never knew he had. Maybe he starts to see magic in everyday things in a way he didn't before. For example, he could make inanimate objects come to life or use spells to protect himself and his friends. Another aspect could be his relationship with Hecate. She might be a strict but loving mother figure, teaching him about the deeper mysteries of the demigod world and how magic fits into it all.
Well, one possibility could be that Percy, already a hero in his own right, finds himself in a situation where Apollo decides to adopt him. Maybe Percy has lost his connection to Poseidon for some reason, and Apollo sees his potential. Apollo could then train Percy in new ways of using his powers, not just related to water but also in areas like prophecy or archery, which are Apollo's domains.
One possible plot could be Percy's struggle with his new identity. Since Hera is the goddess of marriage and family, Percy might find himself in a very different family dynamic. He could be thrust into the middle of godly politics more than ever as Hera's adopted son. For example, he might have to deal with the jealousy of other gods' children who see him as having an unfair advantage.
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.
She might be on a quest to retrieve a lost artifact of Artemis. This could involve traveling to different mythological locations, facing monsters along the way. Her skills as a daughter of Artemis, like her archery and tracking abilities, would be crucial in this journey.
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.
