Some fanfiction portrays dark creatures as having their own society and culture. Werewolves could have a complex tribal structure that is not explored in the original books. This allows for more in - depth world - building within the fan - created stories.
In fanfiction, dark creatures can be more sympathetic. For instance, a vampire might be shown as a victim of his own condition rather than just a menacing figure. This gives readers a new perspective on these usually feared beings.
In some Harry Potter fanfics, magical creatures like the werewolf might be portrayed more sympathetically. Instead of just being seen as dangerous during full moons, they could be shown as struggling with their condition. For example, a fanfic might focus on a werewolf trying to lead a normal life among wizards.
Bird creatures in Harry Potter fanfiction are often portrayed as magical helpers. For instance, owls are not just simple mail carriers. Some fanfictions might depict an owl as a sort of spy, observing things on its delivery routes and reporting back to its master in a subtle way. They can be given personalities too, like being sassy or overly cautious.
Some fanfictions portray dominant creatures as having a major role in the history of the wizarding world. For example, giants could be the original founders of certain magical places. They are depicted as strong and their influence on the early wizarding world is explored, showing their dominance in a historical context.
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.
The relationship could be shown as a mentor - mentee type in some fanfictions. Maybe the Dark Lord, in an alternate reality, decides to teach Harry some of his dark magic knowledge not to corrupt him, but to make him stronger to face other threats in the wizarding world. This would completely change the dynamic between them. They could also be shown as reluctant allies, forced to work together to stop a greater evil that is emerging in the wizarding world. This would involve a lot of tension and distrust between them at first, but gradually they could start to understand each other more.
In some fanfictions, Avada Kedavra is used as a way to explore the darker side of characters. For example, a character who was previously seen as good might be forced to use it in self - defense, which then causes them to struggle with guilt. It can also be used to create alternate universes where the spell has different effects or consequences.
They could be portrayed as having a bit of good in them. For example, they might be under some sort of dark spell that forces them to act as they do, and if that spell is broken, they could be more like guardians of the wizarding world in a different way.
Werewolves are also a popular dark creature in fanfiction. Writers may explore their relationships with other characters in more depth, like how they interact with Hogwarts students. For example, a werewolf character could be a misunderstood outcast trying to find his place.
Apparition in fanfiction can also have different side - effects. While in the original series, the main concern is splinching, in fanfictions, there could be other consequences like leaving a magical trace that can be tracked by dark wizards. This adds an element of danger and intrigue to the story.
In some fanfictions, a Patronus might be more powerful than in the original books. For example, it could have additional abilities like being able to communicate complex thoughts instead of just being a defensive charm. Fanfic authors often like to expand on the magic system.
