Harry Potter and Sirius Black are also paired quite often. Sirius was a very important figure in Harry's life. In slash fanfiction, with Harry being dark and powerful, their relationship can take on a different meaning. Sirius's wild and rebellious nature can be paired well with Harry's new - found power and darker side, creating a relationship that is full of passion and a sense of freedom.
Naruto and Sasuke are the most common pair, no doubt. Their story arc in the official Naruto plot has so many layers that can be re - imagined in a slash relationship. But we also see pairings like Gaara and Naruto in some naruto slash fanfiction. Gaara's initially dark nature and Naruto's ability to reach out to him can be an interesting basis for a relationship in these stories.
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.
Hermione is often one of the most intriguing. In these fanfictions, she might be the one trying to bring Harry back from the dark side. Her intelligence and loyalty are put to the test in a whole new way. Draco Malfoy can also be very interesting. He could be an ally or an enemy to 'Dark Lord' Harry. If he's an ally, it could be because he sees potential in Harry's new power structure. If an enemy, it might be out of his own sense of self - preservation or loyalty to his family's traditional views. And then there's Luna Lovegood. She might be the one character who still sees the good in Harry even when everyone else is afraid. Her unique perspective on the world can add a lot of depth to the story.
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.
Harry Potter himself is often written in these types of fanfiction. He can be either the 'little' or the 'caregiver' depending on the story. Hermione is also a popular choice. Her intelligence can be used in different ways in the DDLB relationship, like being a very nurturing 'caregiver' or a 'little' who is learning a great deal. Ron Weasley is another one. His loyalty can be a big part of the relationship dynamics.
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.
Harry Potter and Jake Long are often paired. Since they are the main characters of their respective series, it makes sense that fans would want to see how they interact. Their different personalities and powers make for an interesting dynamic.
Another popular pairing is Harry Potter himself with Chloe Price. Harry's bravery and Chloe's feisty nature could create some great storylines. Maybe Harry helps Chloe understand the value of life more, while Chloe teaches Harry to be a bit more rebellious in a good way.
Harry and Naruto are often paired as they are both the main protagonists in their stories and share the 'chosen one' archetype. Hermione and Sakura are also popularly paired, as they are both intelligent and strong female characters. Another common pairing is Ron and Choji, perhaps because they both have a bit of a comical side and are loyal friends. Also, Dumbledore and the Third Hokage could be paired in some fanfics, as they are both wise leaders in their worlds.
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.
