There's also 'Fusion of Foes'. This fanfiction is unique because it combines elements of magic and mystery. Percy and Luke find themselves in a situation where they must use their combined powers to solve a mystery that could destroy their world. The relationship between them is portrayed in a very engaging way, with lots of banter and moments of mutual respect that develop throughout the story.
One common theme is the exploration of a forbidden love. Given their complex relationship in the original story, the yaoi fanfiction often plays with the idea of them being together against all odds.
Some popular themes include the struggle between good and evil. Luke has his dark side, and Percy is on the side of good, so that conflict and how it affects their relationship is a big theme. Then there's the theme of trust. It's not easy for Percy to trust Luke at first, but as the story progresses, trust can be built or broken. And the theme of family also pops up sometimes, as their relationships within their own families can influence how they interact with each other.
There's also 'Unexpected Bonds'. In this fanfiction, the author focuses on the character development of both Luke and Percy during the mpreg journey. It shows how they grow as individuals and as a couple. It has some really interesting plot twists that keep readers engaged.
The 'soulmate' trope can be found in Percy x Luke fanfics as well. In this trope, they are destined to be together in some way, whether it's through a magical bond or a prophecy. This trope often adds a sense of fate and inevitability to their relationship. Additionally, the 'secret relationship' trope is used, where they have to hide their feelings and relationship from others in the Percy Jackson world.
It's interesting because it allows for different interpretations of their relationship. In the original story, they are on different sides, but in fanfic, authors can explore what if they had more in - depth interactions? What if they could be friends or something more? It opens up a whole new realm of possibilities for the story.
There's also 'Percy and Luke: A Different Path'. This fanfiction takes a different approach. It imagines if Luke had made different choices early on. Percy plays a key role in guiding Luke towards a better path, and their relationship blossoms as they both learn and grow together.

One plot idea could be a redemption arc for Luke. Maybe Percy helps Luke see the error of his ways and they end up working together to face a greater threat. Another could be a time - travel plot where Percy and Luke meet at a different point in time, like when they were younger, and their relationship develops differently.
