There might also be original characters created by the fanfiction authors. These could be new family elves with unique personalities and backstories. They might interact with the more well - known characters from the Harry Potter universe, adding new layers to the story about the bound family elves.
Dobby is often a common character in such fanfictions. Since he was a well - known house - elf who managed to break free from his binds, he can be a source of inspiration or a mentor figure for other bound family elves in the stories.
One interesting plot could be a family elf trying to break free from the traditional binds while still remaining loyal to their wizarding family. For example, the elf might start to learn magic that is not typically allowed for elves, creating a conflict between their newfound abilities and their old - fashioned duties.
Harry Potter himself is often a common character. He might be involved in the story when he discovers a classmate or friend has the high elf inheritance. His sense of justice would lead him to help protect the one with the inheritance from those who would misuse it.
Another common character could be Hagrid. He was such an important part of Harry's life at Hogwarts and might continue to be in the fanfiction, perhaps coming over to the Potter family's house to show the kids some new magical creatures or give them some advice on their magical studies. There could also be characters from the Ministry of Magic, like some new Aurors who interact with the Potter family in different ways, either as friends or as those who are a bit suspicious of their activities.
Dobby is definitely one of the most popular. His loyalty and his brave actions in the original series make him a great character to build on in fanfiction. Writers often give him more adventures or more complex relationships with other characters.
Snape can be extremely popular in 'Harry Potter and the Bound Prince' fanfiction. Given his complex history and his role in the original series, fanfiction writers like to delve deeper into his motives and his possible connection to the Bound Prince. Some fanfictions might even suggest that Snape had prior knowledge of the Bound Prince and was secretly working towards a greater good related to this mysterious figure all along.
Harry Potter himself is often a central character. Since it's related to the Harry Potter universe, his actions and decisions usually drive the story forward, especially when it comes to dealing with the implications of blood bonds.
Some fanfictions might also involve the villains. Voldemort or his Death Eaters could be interested in the bound collar for their own evil purposes. They might try to steal it or use it against Harry and his friends, which would create a lot of conflict and action in the story.
Harry and Hermione are the main draws. Harry, with his courage and his new 'bound' state with Hermione, might show different aspects of his character. Hermione, being the intelligent and resourceful one, will surely have an interesting role in how their 'bound' relationship unfolds. Also, characters like Dumbledore could be fascinating. He might have some knowledge about their 'bound' situation and his guidance or lack thereof could be an interesting plot point.
Perhaps an unnamed elf who works in the Hogwarts kitchens. She could be the one who always makes Harry's favorite treats, and they strike up a conversation one day. This leads to a deeper relationship and eventually marriage.
There could be many possibilities. It might be an original character created specifically for the fanfiction. However, it could also be a well - known house - elf from the original series, like Dobby, who in the fanfiction somehow comes to be owned by Harry Potter in a different set of circumstances. Maybe Harry saves Dobby in a more complex way in this fanfiction and as a result, Dobby becomes his house - elf.
