There could be a love story. Artemis, now mortal, might develop feelings for Percy that she couldn't as a goddess. This would be a complex relationship as Percy already has his own life and relationships. The fanfiction could explore how they navigate these new emotions.
Artemis as a mortal could be a target. In the demigod world, mortals are often in danger. Percy would have to protect her. This would put him in a difficult position as he has his own quests and responsibilities. The story could revolve around how he manages to keep her safe while still fulfilling his duties.
One idea could be that Artemis becomes mortal to understand Percy's human world better. Maybe she's intrigued by his heroism and wants to experience life from his perspective. This could lead to a whole new set of adventures as she struggles with mortal limitations.
In this fanfiction, Percy becoming a god and marrying Artemis could mean a complete overhaul of the power structure in the mythological world. Artemis might teach Percy more about the secrets of the divine world, especially those related to nature and the hunt. Their union could also bring about a change in how mortals view the gods. Maybe mortals would start to see the gods as more approachable and relatable, especially with Percy being a former mortal himself. And Percy would have to deal with the fact that he is now part of the divine family, which comes with its own set of politics and expectations.
In this fanfiction, perhaps Percy would have to overcome many challenges. Artemis is a maiden goddess, so she might initially be very hesitant. Percy could start by showing his deep understanding of her values, like her love for nature and the hunt. He might bring her unique gifts related to these aspects. And he would need to convince her that their relationship could work, despite the differences between a demigod and a goddess.
In this type of fanfiction, it could be a really interesting concept. Percy becoming a god already changes the whole dynamic of the Percy Jackson universe. And marrying Artemis, who is a virgin goddess in the original mythology, would be a huge deviation. It might lead to a story full of challenges as they have to deal with the reactions of other gods and goddesses. Maybe Percy's new - found godly powers would help him navigate the complex relationship with Artemis, who is known for her independence.
If Percy Jackson becomes mortal in fanfic, he would likely lose his demigod powers. He might struggle to adapt to a normal human life. For example, he would no longer be able to control water or have his superhuman strength. He could face challenges like getting sick more often or not being able to defeat monsters as easily. His relationships might also change. His friends from Camp Half - Blood might have to protect him instead of fighting side by side with him.
If Artemis wants a baby with Percy in fanfiction, it could change the power dynamics in the story's world. Artemis might become more protective and less involved in her usual activities as a goddess. Percy, on the other hand, might gain some new powers or abilities related to Artemis's domain. For example, he could have a stronger connection to nature or the ability to control wild animals. This could also create a new set of enemies for them, as some might see their union as a threat to the existing order.
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.
One possibility is that Percy's relationship with the other demigods would change. Since he is now under the wing of Apollo and Artemis, some demigods might be jealous or curious. He could also become a sort of mediator between the two gods' followers. For example, if there were disputes between the Apollo - related campers and Artemis - related hunters, Percy could use his position to resolve them.
