For fem Harry, her character can be developed by showing her struggle with her new identity in a world with Poseidon. She could start as a bit of a loner, but as she bonds with Poseidon, she becomes more confident. Poseidon, on the other hand, can be developed by showing his softer side. Maybe he starts as a very strict god, but as he gets to know fem Harry, he becomes more lenient and caring.
Fem Harry's character can grow through her experiences with Poseidon's powers. If she has access to some of his abilities, she has to learn to control them, which makes her more responsible. Poseidon can be developed by exploring his past relationships. Maybe he had a troubled relationship with other gods or mortals in the past, and through his connection with fem Harry, he heals and changes. Also, fem Harry can be developed by facing challenges in Poseidon's domain, like dealing with sea monsters. This would make her braver.
To develop Artemis' character, we can focus on her connection to the moon. In the fanfiction, the moon's influence on her could change in the presence of Poseidon. Maybe the moon's magic reacts differently when she's near him, which makes her question her identity and her powers. As for Poseidon, his character can be developed through his interactions with Artemis' followers. If he respects them, it shows a new level of maturity. He could also learn from Artemis about the value of restraint, which is something he lacks in the original myths. This growth in his character would make the fanfiction more interesting and complex.
In this context, Fem Harry's development can involve her learning to use her unique skills as a wizard in combination with the knowledge she gains about the Lamia. She might start using her magic to protect the Lamia from those who would harm them. This would show her growth from a curious student to a defender of a misunderstood species. Also, her relationships with other characters, both human and Lamia, would shape her character. For instance, if she falls in love with a Lamia, it would force her to face the prejudices of her own world and grow stronger in her convictions.
For the female Percy Jackson, you can develop her character by showing her growth in understanding and using her powers. Since she has a connection to Poseidon, she could start off a bit unsure but as the story progresses, become more confident. As for the 'lemon' aspect, if there's a love interest, it can show her vulnerability and a different side of her. For Poseidon, show his fatherly side towards her, his pride or disappointment in her actions which can shape her character development as well.
One way is to show his more vulnerable side. Maybe he's facing a threat that not even his power can easily overcome, and Percy has to help him in a way. This would make him more relatable.
For Fem Naruto, her character could be developed to be more in touch with her femininity while still maintaining her strong - willed and determined nature. She could use her charm in addition to her combat skills to get what she wants. Shisui, on the other hand, could be developed to be more open about his feelings. In the original, he was rather reserved. In the fanfiction, he could be shown to be more vulnerable, especially around Fem Naruto.
Inuyasha's personality can be developed by showing his growth in accepting Fem Naruto. At first, he might be dismissive of her because she's not from his world and seems weak compared to him. But as he sees her tenacity and the power of her ninja techniques, he could start to see her as an equal. His own issues with trust, especially after his past with Kikyo, can be further explored in relation to how he trusts Fem Naruto and whether he's willing to let her into his heart and share his secrets.
For Fem Percy, her character could be developed by showing her struggle with being different from the traditional Percy. Maybe she has some insecurities about living up to the name. As for Scott, his loyalty can be further explored. For example, when faced with a choice between his pack and Fem Percy, how does he decide?
Their relationship could be developed through more shared secrets. For example, Poseidon could reveal a long - hidden prophecy about Percy that only he knows. This would create a deeper bond of trust between them.
For Harry, you can explore his growth in a non - magical world. He might initially struggle without his wand and the familiar magical environment. But as he teams up with Batgirl, he could learn to adapt and use his wits and basic magical knowledge in new ways. For example, he could use his knowledge of potions to create makeshift antidotes for toxins in Gotham. Batgirl, on the other hand, could learn about the existence of magic from Harry, which could expand her view of the world. This new knowledge could make her more open - minded when facing unusual threats in the future.
For Harry, you can focus on his growth beyond what we see in the original series. Maybe he becomes more cynical after all he's been through, and Acheron challenges his views. For Acheron, explore his past more deeply in the context of the fanfiction. Have Harry learn about his traumas and help him heal in some way.
