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.
The 'soulmate' trope is also quite common. Writers often explore the idea that Luke and Mara are fated to be together, whether it's through some Force - related connection or just a deep, unspoken bond that they share. This trope can lead to some really heartwarming and mystical stories.
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.
One popular trope is the 'forbidden love' angle. Since Percy and Luke are on different sides in the original story, in fem Percy and Luke fan fics, this can be intensified. Their love is something that goes against the rules of their world, like the demigod/godly politics. Another is the 'power couple' trope. Fem Percy with her powers and Luke's own skills could be seen as a force to be reckoned with. They might team up against common enemies in ways that deviate from the original plot.
The 'Secret Sibling' trope also shows up. Imagine a story where it's revealed that one of the Weasley kids has a demigod sibling they never knew about. Or that one of Percy's half - siblings is actually a wizard in disguise. There's also the 'Time - Travel' trope. A character could go back in time and change events in both universes. For instance, a demigod could go back and prevent Voldemort's rise to power, or a wizard could go back and stop the Titans from awakening. These tropes add new and exciting twists to the existing stories of both series in fanfic.
A less common but still interesting trope is the 'swap universes' scenario. In this, the characters from Supernatural end up in The X - Files universe and vice versa. They have to navigate the different rules and cultures of the new world while still trying to find a way back home. It can lead to some really creative and humorous situations.
The 'roommate' trope can also be found. Imagine Andrew and Neil having to share living quarters for some reason, like being on a special exy team training program. This forces them to interact more closely, leading to a deeper understanding of each other and the development of their relationship.
One popular trope is the 'enemies to lovers'. It could start with Abby and the reader having some sort of conflict or misunderstanding, and then gradually falling in love as they get to know each other better. Another is the 'hurt/comfort' trope, where the reader might be in a difficult situation and Abby comes to their rescue and offers comfort.
The 'adventure together' trope is quite popular. It involves the futa and male characters going on an adventure, during which their relationship develops. The 'cultural difference' trope can also be seen, especially if the story is set in a fictional world with different cultures. Here, the differences between them can create interesting plot points. Also, the 'redemption' trope, where one of them, usually the futa, might be seeking redemption and the male character plays a role in that journey.
Some fanfics use the 'redemption' trope. Bowser might start off as his typical villainous self, but through his interactions with the reader, he begins to change for the better. There's also the 'mysterious stranger' trope where the reader is new to Bowser's world and he is intrigued by this unknown entity, leading to their relationship developing.
One popular trope is the 'Training Partner' where the reader becomes Goku's training partner. They start off as someone Goku helps to improve their fighting skills, and a relationship blossoms during the intense training sessions. Another is the 'Saved by Goku' trope, where the reader is in danger and Goku swoops in to save them, which then leads to a deeper connection. There's also the 'Power - up' trope where the reader somehow gains power with Goku's help and they go on adventures together.
