Some fanfictions might focus on the idea of redemption or transformation. Maybe a goddess who has been seen as cold or distant in the original series has a change of heart in a relationship with a demigod. This could be the case with a goddess like Hera. The story could show her in a new light, as she experiences love and growth through her relationship with a character like Percy, which is quite different from her traditional portrayal in the Percy Jackson canon.
You can try searching on fanfiction websites like Archive of Our Own (AO3). There are often a lot of Percy Jackson - related fanfictions there, including ones that might involve the goddesses in a lemon - style (romantic or spicy) way. Just use the search bar and type in relevant keywords.
It could be an old enemy of Percy's who sees his relationship with Goddess Lemon as a threat. Maybe a Titan or a powerful monster that wants to use their relationship to its advantage, like using it to create a rift among the gods and demigods.
It could be Annabeth, who was made a goddess in some interpretations. Their kids would be really smart and brave, inheriting Percy's heroism and Annabeth's wisdom.
Another possibility is Hera. Although not typically described as 'curvy' in the original myths in that way, in a fanfiction, she could be reimagined. Her role as queen of the gods could bring a whole new dynamic to the story if she's the curvy goddess in this fanfiction. She might be involved in some sort of power struggle or family drama that Percy gets dragged into.
One idea could be that Percy discovers a hidden side of Goddess Lemon that no one else knows. Maybe she has a special power that only Percy can understand or help her control. Another could be that they go on a quest together, facing challenges that test their relationship and force them to rely on each other.
Another theme is identity. Percy has to re - evaluate who he is when he's a goddess. Does he still have the same values? How does he fit into the world of gods and goddesses now? In some fanfictions, he has an internal conflict about whether he wants to be a goddess or return to his old self. This theme adds a lot of depth to the stories. And often, relationships also play a big role. His relationships with his friends, like Grover and Annabeth, change as he becomes a goddess. They might have to deal with a more powerful and different Percy, which can lead to all sorts of interesting story developments.
In fanfiction, if Percy Jackson was with a goddess, there could be all kinds of amazing adventures. They might go on quests together that are even more epic than the ones in the original books. For example, they could face a super - powerful ancient monster that no one has ever defeated before. And their relationship would bring a whole new dynamic to the story. Percy's mortal - turned - hero qualities would mix with the goddess's divine powers in really interesting ways.
In fanfiction, Percy could marry Annabeth, who becomes a goddess. Given their long - standing relationship in the original series, it would be a natural progression in some fanfictions. Or he could marry Amphitrite, the sea goddess. Since Percy has a strong connection to the sea, this would also make sense. Also, Nemesis, the goddess of revenge, could be an interesting choice. A marriage with her could lead to some complex storylines where Percy has to deal with her vengeful nature while also loving her.
One great female Percy Jackson goddess fanfiction is 'The Goddess's Champion'. In this story, a female character is chosen by a goddess to go on a quest similar to Percy's. It has a really interesting plot with the female protagonist facing challenges in the world of Greek gods and monsters. Another one could be 'A Female's Odyssey in the Percy Jackson Universe' which focuses on a girl's journey to discover her own powers and her connection to the goddesses.
