The Board of Governors could also be portrayed as more hands - on in fanfiction. They might be actively involved in the day - to - day running of Hogwarts, not just making big - picture decisions. For example, they could be the ones to directly handle student discipline cases instead of leaving it all to the professors and the headmaster.
The Board of Governors could also be involved in financial matters in fanfiction. They would ensure that Hogwarts has enough funds for repairs, new equipment, and staff salaries. Maybe they have to deal with a situation where the school's budget is tight due to some magical disasters that damaged parts of the castle.
A lot of fanfictions play around with the Dursleys' relationship with Harry. They could be depicted as having a sort of begrudging respect for Harry. For instance, when Harry starts to show real courage and power, the Dursleys might start to see him in a new light. This is different from the original story where they mostly just try to suppress Harry. Also, some fanfictions might give the Dursleys magical abilities of their own, which completely changes their dynamic with Harry and the wizarding world.
In the original series, Hedwig is mainly a faithful owl companion. But in fanfiction, she can be much more. She could be a magical entity with her own backstory and motives. For instance, some fanfictions might explore her origin in more detail, like she was bred from a special line of owls with unique abilities.
In some fanfiction, inquistors are shown as more corrupt than in the original books. They might take bribes or abuse their power for personal gain. For instance, an inquistor could let a known dark wizard go free in exchange for a valuable magical artifact.
He develops a more rebellious streak. In the original, Harry was quite respectful of authority in the wizarding world. But being raised by bikers, he might question rules more often. For example, he might not be as quick to follow Hogwarts' strict regulations.
When Harry is in Slytherin in fanfiction, his view of the wizarding world may change. He may start to see the grey areas more clearly. Instead of seeing things as simply good or bad, he realizes that there are many factors at play. This makes him more complex as a character. He may also have to deal with the Slytherin legacy of the Dark Arts. He has to navigate through the temptations and warnings related to it. He might study some Dark Arts spells not to use them for evil, but to understand how to defend against them, which is a very different path from what he would have taken in Gryffindor.
In this fanfiction, Harry's development would deviate a lot from the original. His sense of right and wrong would be blurred. Since he's raised by devils, he may not have the same values as the normal Harry. He could be more self - centered, focused on his own survival and power gain rather than the well - being of others. His magical abilities might also develop in a more unorthodox way. Instead of learning the traditional spells for good, he might learn spells that are more harmful or controlling.
He'd likely be more inquisitive about different forms of magic. Instead of just relying on the spells taught at Hogwarts, he'd constantly seek out new magus - based knowledge.
In Harry Potter fanfiction, Merlin can be depicted in many ways. Sometimes he's a benevolent figure, guiding the protagonists from the shadows. Other times, he might be a more complex character with his own motives and secrets. He could be presented as the originator of certain spells or magical techniques that are either lost or only partially understood in the main Harry Potter story. And his appearance might be described as a majestic figure draped in robes and surrounded by an aura of ancient magic.
Well, in a lot of Harry Potter fanfiction, elves are sometimes given backstories that weren't explored in the main series. They can be shown as a more diverse group. There could be different types of elves with different appearances and cultures. Some fanfictions might even have elves interact with other magical creatures in new and interesting ways, like teaming up with centaurs to protect the Forbidden Forest from dark wizards.
