Hermione Granger might also be a central character. Her thirst for knowledge could lead her into situations where she is in the dark, like exploring a new area of magic that has many unknowns. As a child in Hogwarts, she might be trying to solve a mystery that no one else has been able to, and she has to start from a place of not knowing much, or being 'in the dark' so to speak.
Another character could be Neville Longbottom. He started off as a rather timid and often overlooked child in Hogwarts. There could be fanfictions where he is in the dark about his own potential. Maybe he discovers a hidden strength within himself when he is in a difficult or 'dark' situation, such as when facing a dangerous magical creature alone in a dimly - lit part of the school grounds.
Often, Harry Potter himself might be involved. Since he was an orphan, he could be a key figure in understanding how child services work or how they could have been improved in his case. Hermione could also be involved as she is very much into social justice and would likely be interested in the well - being of children in the wizarding world. And there could be original characters created by the fanfiction author, like a dedicated child services worker who is trying to make a difference in the lives of magical children.
Obviously, Harry Potter himself is often involved. He's the hero of the original series, so in fanfiction about a dark dragon, he'd be the one to step up and face the new threat. Hermione and Ron would likely be by his side too, as they are his closest friends.
In addition to the main trio, characters like Draco Malfoy could be a major part of the story in 'Harry Potter Dark Paladin' fanfiction. Draco's complex relationship with the dark side in the original series could be further explored in relation to the Dark Paladin. There could also be original characters created specifically for the fanfiction, who might be fellow Dark Paladins or those who have a connection to the dark powers that the main Dark Paladin is using.
Harry Potter himself is often a main character. Since he has a connection to Voldemort, he's likely to be involved in any dark discoveries related to the Dark Lord.
Harry Potter himself is often a central character. Since he's the main character in the original series, it makes sense that in 'Harry Potter Dark Gifts Fanfic' he would be involved. Writers might explore how he copes with or uses a dark gift.
Another character could be Draco Malfoy. There could be fanfiction where Draco, having been on the wrong side for a long time, now has a change of heart and wants vengeance against his own family or the Death Eaters who used him. He might use his knowledge of the Dark Arts that he learned from his family, but now turn it against them in a bid for redemption through vengeance.
Harry Potter himself could be one of the main characters in such fanfiction. Maybe he gets an automail limb after a particularly dangerous encounter with Voldemort. Hermione might also be involved, using her vast knowledge to help understand and improve the automail technology within the wizarding context.
Harry Potter himself is often a central character. Since he was the one destined to defeat Voldemort and destroy the Horcruxes in the original story, many fanfictions continue his journey with Horcruxes in new and different ways. Hermione Granger also features prominently. Her intelligence would be crucial in understanding the nature of Horcruxes and finding ways to deal with them.
Well, Harry Potter himself is often involved. Since he is the main character in the original series, in fanfiction with a genie, he could be the one to find the genie and interact with it. For instance, he might be the one to use the genie's wishes to save his friends or defeat his enemies.
Ron Weasley can also play an important role. He might be the one who accidentally causes an accident that sends someone to the hospital, and then feels really guilty about it. So he spends a lot of time in the hospital wing trying to make it up to the injured person, while also getting into some comical situations with the other patients and the Healers.
