There's the 'Power of Empathy' trope as well. Since Ariel is different from the original Ash, she might rely more on her empathy to connect with Pokémon. This trope shows how her ability to understand the Pokémon on a deeper level gives her an edge in battles and in her overall journey. It's a really interesting take on the Pokémon world with a fem Ash character.
There's also a fanfic called 'Ariel: The New Ash'. In this one, Ariel as Ash faces different challenges compared to the original Ash. It delves deeper into her relationships with other trainers and Pokémon. It has a great plot that keeps you hooked from start to finish, and the way the author describes the Pokémon battles is really exciting.
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.
One popular trope is the 'enemies to lovers' scenario. Since in the original they might be at odds, in fanfiction, it can be interesting to see how their relationship develops from hostility.

One popular trope is the 'fish out of water' situation.

For example, her reaction to nen compared to chakra can be really entertaining.
A common trope is the 'romantic entanglement' trope. Writers often pair the fem Harry Potter with various characters from Game of Thrones. It could be with Jon Snow, creating a story of two outcasts coming together.

There's also the 'mentor - mentee' trope where she either mentors someone in Westeros about magic or is mentored by someone about the ways of Westeros.
The 'power couple' trope is quite common. Since both are strong leaders in their own right, fanfiction often portrays them as a couple who can take on the world together. They use their combined strength, wisdom, and influence to bring about change in Westeros or beyond. Also, the 'redemption' trope can be found, where one of them has made mistakes in the past and the other helps them redeem themselves.
