Hermione Granger is often a character that is transformed in these fanfictions. She's a very popular character with a strong personality, so seeing her in a different gender role can lead to all sorts of interesting plot developments.
Draco Malfoy is frequently transformed in such fanfictions too. Given his complex character and his family's standing in the wizarding world, a gender transformation for him can create a lot of drama. It can change his interactions with other Slytherins, his rivalry with Harry, and his own self - image within the strict hierarchies of the wizarding society.
Draco Malfoy is often a character that gets transformed in fanfiction. A transformation for him could lead to a redemption arc. For example, if he was transformed into a house - elf, he would have to experience the life of those he once looked down upon, which could change his perspective. Luna Lovegood is another popular choice. Her already unique personality could be enhanced or changed through transformation, like turning her into a celestial being related to the stars she's so interested in.
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 and Hermione are often swapped. Since Hermione is such a strong and capable character, it's interesting to see her in Harry's role. Also, Neville and Harry are commonly swapped as Neville also has the potential to be a hero.
Harry Potter himself is often included. He's the main hero of the original series, so it makes sense. Hermione Granger is also a common choice. Her intelligence and strong - willed nature make her an interesting addition to a harem. Ron Weasley can be included too, though perhaps less frequently. And then there are characters like Draco Malfoy. His complex personality can add a lot of drama to the harem dynamic.
Harry himself is also a common character for gender - bending. As the main character, changing his gender can completely shift the narrative. It allows for new interpretations of his hero's journey and how he deals with the challenges of the wizarding world as a female. Fans are interested in seeing how a female Harry would handle things like the Triwizard Tournament or facing Voldemort.
Hermione is often gender - swapped. A male Hermione would be interesting as he might approach his studies and friendships differently. Harry is also a top pick. A female Harry could add a different flavor to the story, especially in her relationships with other characters like Ron and Hermione. And Ginny. A male Ginny could change the way we see the Weasley family and his relationship with Harry, perhaps being more of a laid - back friend rather than a love interest at first.
Definitely Harry. Since he is the main character, a gender - bent version of him can lead to many different plot twists. Fans are often interested in seeing how a female Harry would interact with the other characters and change the course of the story.
Definitely the Potter family. Harry Potter himself is a central figure, and so exploring his ancestors like his father James Potter and his grandparents is very common. The Weasley family is also popular. With so many siblings and their parents, there are a lot of family relationships to play with. And of course, the Black family. Their family tree is filled with complex characters like Sirius Black, and fanfiction often delves deeper into their dark past and the family's influence on the wizarding world.
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.
Harry and Hermione are very commonly switched. It's probably because they are two of the main characters with very different personalities. Their friendship and the contrast between their skills and abilities make for an interesting body - switch scenario. Another common pair is Harry and Draco. The good - guy - bad - guy dynamic creates a lot of potential for drama and exploring different perspectives when they switch bodies.
