In fanfic, magical creatures may have different behaviors compared to the original books. For example, a Thestral in fanfic might be more social towards certain characters than in the books. Also, their appearances could be altered. A Hippogriff in a fanfic could have a different color or pattern on its feathers. And sometimes, new abilities are given to them. Maybe an Occamy in fanfic can communicate telepathically which it can't do in the original.
One major difference is that in Harry Potter fanfic, magical creatures can be the central focus of the story, whereas in the original books they often play supporting roles. For example, a fanfic could be entirely about a group of wizards trying to protect a colony of Phoenixes from dark wizards. In fanfic, the powers of magical creatures can be exaggerated or minimized. An Acromantula could be made much larger and more powerful, or a Grindylow could be made less menacing. Also, fanfic allows for the creation of new magical creatures through the combination or mutation of existing ones, which is not present in the original books.
In fanfiction, magical creatures often have more complex personalities. For example, in the books, the Blast - Ended Skrewt is mainly just a strange and dangerous creature. But in fanfiction, it could be given a backstory that makes it more sympathetic. Also, new abilities might be added. The Thestral might be able to communicate telepathically in some fanfictions, which is not in the original books. And sometimes, the relationships between magical creatures and characters are explored more deeply in fanfiction.
In the original Harry Potter series, creatures like the Dementors have a specific origin and role. However, in fanfics, we might see Dementors being controlled by a new kind of magic or even having different powers. Some fanfics might make Dementors be able to transform into other forms, which is quite different from what we know in the books. This is because fanfic authors want to explore new storylines and add twists to the familiar Potter world. They can take a well - known creature and give it new abilities or backstories to fit their own creative vision for the story.
In the original books, the creatures have well - defined characteristics set by J.K. Rowling. But in fanfiction, they can be drastically altered. For example, the werewolves in the books are mainly seen as dangerous during full moons. In fanfiction, a werewolf might be able to control their transformation at will and be a more complex character, perhaps even a hero. So the nature of the creatures can be completely reimagined in fanfiction.
The magical items in fanfiction often differ from those in the original books in terms of their origin and purpose. In the books, items like the Philosopher's Stone have a very specific backstory and are crucial to the main plot. In fanfiction, similar - looking items might be created for different reasons, like a 'fake' Philosopher's Stone made by a dark wizard to deceive others. Moreover, fanfiction may introduce items that are hybrids of existing ones, which is not common in the original series. For instance, a combination of a broomstick and a portkey that can fly you to different magical locations with a simple incantation.
In the original books, boggarts are mainly used for comical relief in some cases, like when Neville's boggart turns into Snape in his grandmother's clothes. In fanfic, they can be much darker. For example, a boggart could be a character's worst nightmare come to life in a more extreme way, like a character seeing their entire world destroyed. Fanfic boggarts might also have different rules. They could be harder to defeat or have the ability to morph into multiple forms instead of just one.
The rituals in the original Harry Potter books are mainly designed by J.K. Rowling to drive the main plot forward. For example, the opening of the Chamber of Secrets has a sort of ritualistic aspect to it. However, in fanfic, rituals can be used to explore different aspects of characters. A character might perform a ritual to overcome their fear, which is not really a focus in the original books. Fanfic rituals can be more character - centric rather than plot - centric.
In fanfiction, Bubotubers might have enhanced abilities. For instance, they could be made to move around more actively compared to the rather stationary ones in the books.
The weapons in the original Harry Potter books are mostly traditional magical items like wands, swords (like Godric Gryffindor's sword), and potions which can be used in a sort of weapon - like way. However, fanfiction weapons are often much more elaborate. Fanfiction might introduce things like a ring that can teleport the wearer anywhere in Hogwarts or a necklace that gives the user the power to control the weather. These weapons are not bound by the limitations of the original book's lore as strictly, so they can be more creative and extreme in their capabilities.
Fanfiction often gives boggarts more abilities or different rules. In the original books, the Riddikulus spell was a fairly straightforward way to deal with them. But in fanfic, boggarts might be harder to defeat, perhaps requiring a combination of spells or a deeper understanding of one's own psyche. They could also have the ability to influence the environment in different ways, like creating illusions that are more difficult to distinguish from reality.
In fanfiction, magical creatures often have more exaggerated abilities. For example, in canon, a unicorn is mainly known for its purity and healing powers. But in fanfiction, a unicorn might be able to communicate telepathically with wizards on a much deeper level. Another difference could be their behavior. Canon might show a centaur as a bit aloof and mysterious, while in fanfiction, a centaur could be much more involved in Hogwarts affairs, like teaching secret classes.
