I think Belle from the Disney princesses would be the most interesting. She is intelligent and curious, much like Hermione in the Harry Potter world. In this fanfiction, she would be eager to explore the wizarding world, learn about magic, and share her love for books with the Hogwarts students. She could also use her kindness and ability to see the good in others to bring out the best in some of the more troubled characters in the Harry Potter universe, like Draco Malfoy perhaps.
Hermione would be really interesting. In a fanfiction like this, she would be fascinated by the Disney princesses. She could study their different forms of magic and their unique cultures. Her in - depth knowledge of magic would help bridge the gap between the two very different fictional universes. Also, she could learn a lot from the princesses about leadership and courage in different ways compared to what she has experienced in the wizarding world.
Snow White could be very interesting. In a 'Harry Potter Disney Princess Harem Fanfiction', her pure heart and kindness would stand out. She could befriend the house - elves at Hogwarts and teach the students about the importance of treating all beings with respect. Her ability to charm animals could also be used in the wizarding world in ways not thought of before. And her experience with the Evil Queen would give her an understanding of facing great evil, which she could share with Harry and his friends when they encounter dark wizards.
One possible plot could be that a powerful wizard from the Harry Potter world accidentally creates a portal that brings together various Disney princesses into the wizarding world. Harry Potter and his friends are initially shocked but then have to work with the princesses to face a new dark threat that emerges due to this strange union. The princesses' unique skills and the magic of the wizarding world combine in unexpected ways to fight the enemy.
Harry Potter himself would be very interesting. Combining his wizarding skills with Kryptonian powers would make him an extremely powerful character. He could be the bridge between the two worlds and use his new powers to protect both the wizarding world and the world of Kryptonians on Earth.
Definitely Harry Potter and Simba. Just think about it, Harry, who has faced so many challenges in the wizarding world, could share his experiences of growing up and facing difficulties with Simba, who also had to overcome many hardships to become king. It would be an interesting combination of two strong - willed characters.
Snape and Madarao would be an unexpected but fascinating pairing. Snape's brooding and complex personality could interact in an interesting way with Madarao's more straightforward and loyal nature. Snape could perhaps study the unique yokai magic associated with Madarao, and Madarao could be both amused and intrigued by Snape's potions and spells.
Definitely Harry Potter and Rias. Rias is used to leading and being in control, but Harry has his own strong sense of justice and leadership. Their interactions could be full of power plays and mutual respect as they try to figure out how to work together.
It could be Aquaman. He is so different from the wizards in the Harry Potter universe. His fish - like abilities and his role as a king would make for some great interactions with the Hogwarts students and professors. He could teach them about the ocean and its secrets, while also being amazed by the magic of wands and potions.
Percy would be really interesting. His ability to control water and his laid - back yet brave personality would contrast well with the more formal wizarding world. He could make some really funny and unexpected interactions with the Hogwarts students and teachers.
I think Hermione would be really interesting. She's already very intelligent and resourceful. If she got the Venom symbiote, she could use its powers to access areas that are normally restricted in the wizarding world, like the restricted section of the library, and find new spells and knowledge. She could also use the symbiote's physical abilities to protect her friends during dangerous situations.
I think Harry Potter and Nick Burkhardt would be an interesting pairing. Harry has his experience with fighting dark magic and Nick has his knowledge of the Wesen world. They could learn a lot from each other. Harry could teach Nick about some of the more complex spells, while Nick could introduce Harry to the different types of Wesen and how to deal with them.
Doctor Strange would be an interesting character to focus on in a Harry Potter MCU fanfiction. He already has knowledge of magic in the MCU, but it's a different kind of magic compared to that in Harry Potter. He could compare and contrast the two magics, and perhaps even learn new spells from the Harry Potter universe. His presence could also bridge the gap between the two universes in terms of magic.
