Percy and Alex from the Unwanteds would be really interesting. Alex has the power of transformation, and seeing how Percy would react to that and how they could use that power together in a fight or a mission would be cool.
I think Percy would be the most interesting. His laid - back yet brave personality would contrast with the more serious Kanes, creating some really fun dynamics.
The story in the fanfiction could start with Percy getting lost and somehow ending up in the world of the Unwanteds. At first, he might be confused and on guard. But as he starts to understand the Unwanteds and their situation, he decides to help. He could use his ability to communicate with sea creatures to get information or assistance. The Unwanteds could be amazed by Percy's powers and his connection to the gods. They might ask him to train them in combat or survival skills. And in return, the Unwanteds could share their unique magical arts with Percy, which could give him an edge in future battles in his own world.
Percy would be very interesting. His charm and his ability to get into and out of trouble are always fun to read about.
I think Anubis could be an interesting character in this fanfiction. He has his own mysterious nature in the Kane Chronicles. If he meets Percy, there could be some really strange and exciting interactions. Anubis could be intrigued by Percy's connection to the Greek gods and his unique powers. Maybe Anubis would even offer some help or pose a new threat, depending on how the story is written.
I think Yu and Joker would be really interesting. Yu is a calm and collected leader in Persona 4, while Joker is more of a cool and strategic leader in Persona 5. Their different approaches to leading their teams could create some great drama and cooperation.
It could be Carter Kane. His leadership skills and his deep knowledge of Egyptian magic would be crucial in the story. He is more reserved than Sadie but has a strong sense of duty. When paired with Percy, he could learn a lot about different ways of fighting and protecting, and his character growth as he adapts to working with demigods would be an interesting aspect of the fanfic.
I think Percy and Tyrion would make an amazing combination. Tyrion is known for his intelligence and sharp wit, while Percy has his demigod powers. Together, they could outsmart their enemies and come up with some really creative strategies, whether it's dealing with the Lannisters or some other threat from Percy's world.
Kim and Marco would also be a great combination. Kim is a confident and capable hero, and Marco is very loyal and has his own set of skills. They could work together really well. Maybe Marco could help Kim understand some of the more out - there aspects of Star's world if they end up there, and Kim could teach Marco some of her combat techniques.
Hermione and Sakura would be a great combination. Hermione is highly intelligent and book - smart, while Sakura is a skilled medical ninja with her own growth arc in terms of strength and confidence. They could exchange knowledge, with Hermione teaching Sakura about the complex magic theories and Sakura showing Hermione some of the medical ninjutsu. They could also work together to solve problems, using their combined wits and skills.
Hermione Granger and Sherlock would be an interesting pair. Hermione is extremely intelligent and well - read in magic. Sherlock is a master of deduction. She could introduce him to the complex world of magic, and he could help her with his logical thinking when it comes to non - magical mysteries at Hogwarts. They could also have some really interesting debates about the nature of knowledge, whether it's through magic or pure logic.
