The Weasley twins, Fred and George, are also very likely to be main characters involved in the trolling. They are known for their pranks in the original Harry Potter series, so in this fanfic, they could be Harry's partners in crime when it comes to trolling everyone.
Hermione might also be involved in a different way. She could be the one who comes up with clever and devious plans for trolling, using her vast knowledge of magic and the wizarding world. While she's usually more studious, in this fanfic she might let loose a bit and use her intelligence for some light - hearted trolling.
Most likely, Harry Potter himself would be one of the main characters doing the trolling. Given that it's in the title, he's probably at the center of the humorous and mischievous actions.
One interesting scenario could be when Harry uses his magic in a really unexpected and humorous way to troll his professors. For example, he might make Professor Snape's potions ingredients start dancing during a class, just to see Snape's reaction.
Obviously, Harry Potter would be the main character. He is the one doing the saving. Ron Weasley and Hermione Granger are also likely to be main characters as they are Harry's closest friends and often by his side in his adventures. Dumbledore might also play an important role, even if he's dead in the original story, his influence could still be there guiding Harry. And of course, there would probably be villains, perhaps Voldemort or some new dark wizard created for this fanfic.
Dumbledore could also be an important character. He might be the one who tries to figure out what's wrong with Harry and tries to reverse this hatred. Another character could be Snape. He might see this as an opportunity to make Harry's life even more difficult or, on the other hand, might be secretly trying to help him get over this hatred.
I don't know for sure as I haven't read this particular fanfic. But it could have the main character be an original creation with the 'lionheart' trait, or it might center around a well - known Harry Potter character like Harry himself with some new 'lionheart' - inspired story arc.
Well, in many Harry Potter fanfics, even those named 'the change', the main characters often include Harry, Hermione, and Ron. However, depending on what the 'change' is about, new characters could be introduced or existing minor characters could be promoted to main character status. For example, if the change is about the Slytherin house becoming more inclusive, we might see Draco Malfoy taking on a more central role in the story, along with the usual trio.
It could be a Muggle - born protega. This character would face unique challenges as they try to protect the wizarding world while also dealing with their own identity issues. They might have friends among the Hogwarts students, and together they form a group to counter a new evil force that targets both Muggles and wizards.
Without reading it, it's hard to say. But it could feature the main characters from the original series like Harry, Hermione, and Ron as they are usually central in most Harry Potter fanfics. They might be the ones trying to solve the conundrum.
Since it's a fanfic, the main characters could be a mix of new and existing characters from the Harry Potter world. Maybe it has Harry, Ron, and Hermione in some sort of mentoring role to the new hunters. Or it could be entirely new characters who are on a journey of their own, exploring parts of the wizarding world that haven't been fully explored in the original series, like some hidden areas where they need to hunt for something important.
Most likely, the main character is the healer. They could be an original character created for the fanfic. There might also be appearances from well - known Harry Potter characters like Harry himself, Hermione, and Ron. Maybe the healer has to work with them to solve some sort of magical health crisis in Hogwarts or the wizarding world at large.
In addition to Harry, there could be a unique snake character that is a main character. This snake could have its own personality and motives. It might be a magical snake that has been around for a long time and has knowledge of hidden secrets in the wizarding world. Dumbledore could also be a main character as he often guides Harry in the original series and would likely do so in this fanfic as well, especially with Harry's new snake - related situation.
