The 'enemies to lovers' trope is also quite popular. Maybe they start off on the wrong foot because their methods of protecting the ocean are different. But as they get to know each other better, they realize they have more in common than they thought. There's also the 'lost in a strange world' trope where the female Percy Jackson gets lost in the underwater world of Aquaman and he has to guide her. During this process, they form a bond.
A common trope is the 'fish out of water' situation. The female Percy Jackson, used to the world of Greek mythology, is suddenly in Aquaman's underwater domain. It creates a lot of humorous and interesting situations as she tries to adapt. Another trope is the power struggle. Since both have power over water, there could be a bit of a tussle about who's in charge when it comes to water - related problems.
One more trope is the 'culture clash' trope. The female Percy Jackson comes from a world of Greek demigods with its own set of rules and beliefs, while Aquaman is from Atlantis with a completely different culture. This can lead to misunderstandings at first, but as they interact more, they start to appreciate each other's cultures. It can be really interesting to see how the author resolves these differences in the fanfiction.
A less common but still interesting trope is the 'power exchange' trope. Since Percy has her demigod powers and Dean has his hunting skills and knowledge of the occult, they could end up teaching each other things. For example, Percy could teach Dean how to use water as a weapon in a more efficient way, and Dean could show Percy how to handle modern weapons. This trope allows for a lot of character development and interaction between the two.
A common trope is the 'fish - out - of - water' situation. The female Percy Jackson is suddenly in the world of the Avengers, which is very different from her demigod world. Another popular one is the 'power - clash' trope, where her demigod powers interact in unexpected ways with the superpowers of the Avengers.
One popular trope is memory recovery. In many of these fanfics, Percy has to gradually remember his past life as a demigod. It adds an element of mystery and character exploration as he figures out who he was. Another is the 'fish out of water' situation. Since he's reincarnated, he often has to adapt to a new world or time period, which can lead to some really interesting and comical situations.
One common trope is the 'fish out of water' situation. For example, Percy suddenly finding himself in Hellboy's world and having to adapt to the much darker and grittier environment. Another trope is the 'team - up against a greater evil'. This usually involves Percy and Hellboy combining their unique skills to take on a powerful villain that threatens both their worlds.
One popular trope is the 'fish - out - of - water' scenario. For example, Percy might find himself in the world of Danmachi and have to adapt to its different rules and cultures. Another common trope is the power - up trope. Characters from Percy Jackson's world might gain new abilities in the Danmachi setting or vice versa.
The 'powerful outsider' trope is also popular. Fem Percy is a powerful demigod, and when she enters the Avengers' world, she often has to prove herself to the team. This leads to some great action scenes and character development as she shows what she can do. It's like she's an unknown variable that the Avengers have to figure out how to work with.
Another common trope is the 'powerful female lead'. Writers love to explore how a female Percy can be even more badass. They often give her new powers or enhanced versions of her existing ones. In crossovers with other hero - based universes, she usually ends up being a key player in saving the day, like in a crossover with the X - Men where she uses her water powers in unique ways to fight mutants and villains.
A common trope is the 'fish - out - of - water' one. Fem Percy Jackson is used to the world of Greek gods and demigods, so when she's in Gotham, she has to adapt quickly. Another popular trope is the 'powerful - duo' trope. She and Batman team up and their combined skills and powers make them an unstoppable force against the villains.
The 'Redemption Arc' is also common. Some fanfictions focus on a character who has made mistakes in the past, like a minor villain, and they get a chance to redeem themselves in the House of Hades setting. It adds an interesting layer of depth to the story.
One great fanfic could be where the female Percy Jackson meets Aquaman during an underwater adventure. Maybe she's on a quest that leads her to the underwater kingdom. The story could explore their different powers and how they team up to face a common threat, like a sea monster that's causing chaos in both the demigod and Atlantean worlds.
