Another common character to be Hermione's mate in fanfiction is Ron Weasley, which might seem more in line with the original series at first. However, these fanfictions often take a different turn from the canon and explore deeper emotional and magical aspects of their relationship as mates.
In a lot of these fanfictions, Harry Potter himself could be the one who is Hermione's mate. This often changes the whole dynamic of the original friendship triangle in the Harry Potter series. It allows for new storylines to be explored, such as how their relationship affects their fight against Voldemort.
Obviously, Hermione Granger and the Weasley family members are the main characters. This includes Ron Weasley, who is Hermione's friend and often has a complex relationship with her in fanfiction. Then there are the other Weasley siblings like Fred, George, Ginny, etc. Each of them can bring their own unique personalities and storylines to the fanfiction.
Sometimes, characters from other magical schools or even non - human magical creatures could be important. For instance, a centaur who has some special knowledge about the prophecy that concerns Hermione. These additional characters add more depth and variety to the fanfiction.
Draco Malfoy could be a likely character. He was a Death Eater (or on the verge of becoming one), and his relationship with Hermione has always been complex. There's a lot of potential for a story between them as they have a history of rivalry and yet could potentially find common ground or unexpected feelings for each other.
Obviously, Hermione is the central character. Harry and Ron are often also important. They might be in trouble and Hermione has to save them. For example, they could be captured by Death Eaters and Hermione devises a clever plan to rescue them.
Hermione is the key character in these fanfics. But it's not uncommon to have magical creatures play important roles as well. For example, a unicorn whose milk is the focus of the story. Or a house - elf who has some knowledge about a special milk that Hermione is trying to understand. Additionally, characters from other wizarding families might be included to create more complex relationships and storylines around the milk concept.
The two central characters are Jacob and Bella. Jacob, who has the goal of claiming Bella as his mate, may bring his own set of traits like his strong will and determination. Bella, on the other hand, is an important character as she is the focus of Jacob's claim. She might be portrayed as a character who is trying to understand this new aspect of their relationship and how it fits into her life.
Obviously, Ron and Hermione are the main characters as the baby's parents. Their personalities play a big role. Ron's humor and Hermione's intelligence are often passed on to the baby in different ways in the stories. Also, Harry Potter sometimes makes an appearance as the baby's godfather or just as a close family friend.
Obviously, Harry and Hermione are the main characters. Harry is the one who undergoes the transformation into Hermione. Ron is also often involved as he is their close friend and his relationship with both Harry and Hermione is an important aspect. Dumbledore might also make an appearance as he is always aware of what's going on in Hogwarts and could play a role in either helping Harry deal with the transformation or in uncovering the cause of it.
Obviously, Harry himself is a main character. His parents, if the story involves flashbacks or some kind of time - travel or memory retrieval, could also be important. And his siblings, if the fanfiction gives him some, would be main characters as well.
Obviously Naruto is one of the main characters. His father, Minato, and his mother, Kushina, are also likely to be main characters as they are part of his family. And of course, if Naruto has a family of his own in the fanfiction, his wife and children would also be important characters.
