Mermen in fanfiction could also have different magical abilities. While in canon we don't see much of their magic, in fanfiction they could have unique spells or powers related to water. For instance, they might be able to control the weather over water bodies or create illusions within the water that can deceive even the most powerful wizards.
Fanfiction often gives mermen a more detailed culture. In the 'Harry Potter' books, we only get a glimpse of their society. But in fanfiction, we can see their traditions, their social hierarchies, and how they interact with each other. For example, there could be merman clans with different specialties and roles, and their relationship with the wizarding world could be explored more deeply, such as trading magical items or sharing magical knowledge.
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.
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.
In fanfiction, their friendship can be more openly affectionate. In the canon, they have a complex relationship with a lot of rivalry and tension. But in fanfics, they might be shown hugging more often or openly expressing their care for each other without the usual hesitations. For example, in some fanfictions, they might have sleepovers and just talk about their feelings all night.
In fanfiction, Ahsoka might be portrayed as more conflicted about the Jedi Code. For example, she could be more open to Ventress's ideas about power and freedom, which is different from her more by - the - book nature in canon. Ventress, on the other hand, could be shown with a softer side, perhaps having more remorse for her past actions than she does in the official storylines.
In fanfiction, sometimes Harry Potter's heroism is shown through different relationships. Maybe he has a closer bond with some characters that were not as emphasized in the original books, and this relationship drives his heroic actions in a new way. Also, the challenges he faces could be more complex or unique compared to the ones in the original story. In the original books, the main threat was Voldemort, but in fanfiction, he could be dealing with all kinds of new dark forces or complex moral dilemmas that further define his heroism.
In fanfic, Hermione's character might be portrayed as even more assertive and independent than in canon. For example, she could take on leadership roles more quickly and with more confidence when paired with Albus. Albus, on the other hand, may be shown as more open - minded to new ideas, especially those brought by Hermione, compared to how he might be perceived in the original works.
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.
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.
