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 the members of Dumbledore's Army could also play this game. It would be a way for them to bond in a more light - hearted way outside of their usual training. Ginny, Luna, and Neville would all be great candidates. It could be a moment of relaxation for them in the midst of all the chaos at Hogwarts during the darker times.
One of the most likely pairs is probably Neville and Luna. They both have unique personalities and a connection in the books. Their pairing in spin the bottle fanfiction could lead to some really magical and off - beat adventures or conversations. Then there's Fred and Angelina. Given their history in the Quidditch team, if the bottle points at them, it could bring out some old memories and new feelings. And of course, we can't forget about Cedric and Cho. Their relationship was a big part of the story, and if they get paired in the fanfiction, it could explore different aspects of their relationship that weren't fully covered in the original books.
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.
Probably Sasuke. Naruto has always had a strong connection and rivalry with Sasuke. If the bottle landed on Sasuke, it would lead to an intense and interesting moment, whether it's a friendly challenge or a more serious conversation about their past and future.
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 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.
I think Hawkeye and Scarlet Witch could have great interactions. Hawkeye is a down - to - earth, practical guy, while Scarlet Witch has her powerful and sometimes unpredictable magic. If the bottle lands on them, they could have a conversation about how to use their skills in different ways. For example, Hawkeye could teach Scarlet Witch some basic archery skills while she shows him some new ways to think about using his environment during a fight.
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.
Percy Jackson and Carter Kane would be a great pair. Percy is used to the Greek mythological world and its challenges, while Carter has a deep understanding of Egyptian magic and mythology. Their different perspectives could lead to some interesting teamwork, like when they face a monster that has aspects of both Greek and Egyptian mythology, such as a Sphinx with the ability to use water attacks like a Greek hydra.
