Thor and Hagrid could be paired. Thor is a powerful god from another realm, and Hagrid has a deep connection with magical creatures. Thor could learn about the unique magical creatures in the Potterverse from Hagrid, and Hagrid could be in awe of Thor's godly powers. Their interactions would bring a fun and unique element to the fanfiction.
Harry Potter and Captain America are likely to be paired. Harry is used to leading a group against dark forces, and Captain America is a natural leader too. Their leadership styles could complement each other. Also, they both have a strong sense of justice.
Harry Potter and Nate Ford could be a likely pair. Harry's experience with facing great evils and his leadership skills combined with Nate's strategic mind in planning heists would make for an interesting dynamic. They could learn from each other's methods of problem - solving.
Harry Potter and Ichigo Kurosaki are very likely to be paired. They are both the main protagonists in their respective series. Harry has his strong sense of justice and magical powers, and Ichigo has his determination and Soul Reaper abilities. They could form a great partnership to fight against common enemies.
Ron and Uryu might be paired. Ron has his own insecurities but also his moments of great courage, much like Uryu. They could bond over their skills in combat, Ron with his magic and Uryu with his Quincy powers.
Yoko from Gurren Lagann and Hermione Granger could be paired. Yoko is a strong and independent female character, and Hermione is brilliant and resourceful. They could team up to face challenges, with Yoko providing her combat skills and Hermione her vast knowledge of magic. Their combination could be a force to be reckoned with in the fanfic.
Luna and Neville would be another possible pair. They are both somewhat outcasts in their own ways in the Harry Potter world. In the fanfic, when the bottle lands on them, it could lead to a really sweet and heartwarming moment. They could bond over their shared experiences and unique perspectives on magic, and perhaps develop a deeper relationship.
I think Harry Potter and Captain America would be likely to form an alliance. Harry is a natural leader who has faced great evil in his world, and Captain America is all about justice and doing what's right. They would respect each other's values and leadership skills. They could lead their respective teams, the Hogwarts students and the Avengers, in the fight against the common enemies like Voldemort and Thanos.
Finn from Glee and Harry Potter himself could be paired in fanfiction. Finn has his leadership qualities in the Glee club, much like Harry has in the wizarding world. They could bond over their responsibilities and face challenges together, whether it's fighting off the Death Eaters or dealing with high - school - like rivalries in the case of Finn in the Glee world.
Hermione is a very likely candidate. With her intelligence, she could easily start a business. For example, she might open a library - like establishment but with rare and restricted magical books that she has managed to collect through her research. She could charge a membership fee for witches and wizards to access these valuable resources.
I think Thor would have a strong bond with Fem Harry. He comes from a world of magic himself, so he would understand her magical abilities better than some of the others. Also, his big - hearted nature would make him very protective of her.
Harry Potter himself is often paired with Madam Hooch in fanfiction. Given their connection through Quidditch and flying lessons, it's easy to see why writers would explore their relationship further. Maybe Harry has some trouble with a new flying technique and Madam Hooch spends extra time with him, leading to a deeper bond.
