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.
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.
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.
One common theme could be the exploration of a forbidden relationship. Since Percy is a demigod and a goddess is, well, a goddess, there's likely to be a lot of tension around the relationship being taboo in some way.
I'm not a big advocate for 'lemon' fanfiction as it often goes against the intended spirit of the original work. However, if you're just interested in well - written stories about Percy and Sally's relationship, look for ones that explore their bond, like how Sally's love and support shaped Percy. Some fanfictions might show flashbacks of their time together or Sally's influence on Percy's decisions, which can be really interesting to read.
A popular 'Percy Jackson x Annabeth' fanfic is 'Together Forever'. This fanfic shows their relationship in a very real - life - like way. It shows their arguments and how they make up. It also includes some great action scenes that are in line with the Percy Jackson universe. And then there's 'Annabeth's Choice' which is really interesting as it explores what Annabeth would do when faced with a difficult decision that could impact her relationship with Percy.
Yes, there are some out there. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'Percy Jackson x Sally Lemon' and you'll likely find a variety of stories with different interpretations and plotlines.
Percy's development could involve him using his skills in a new way. For example, his ability to control water could be combined with Elsa's ice in creative ways. This would make him more adaptable. Elsa could develop by seeing Percy's loyalty to his friends and trying to form deeper connections herself. As they interact more, they could influence each other's values. Percy might become more patient like Elsa, and Elsa could become more bold like Percy.
Well, it's controversial because it distorts the nature of their relationship. In the books, Sally is a loving mother to Percy. A 'lemon' fanfiction in this context implies inappropriate and unethical relationships. It also can be very off - putting to fans who love the series for its themes of friendship, family, and heroism. This kind of fanfiction takes things in a direction that is not in the spirit of the original work and can make people uncomfortable.
