The original Harry Potter series only gives us a basic understanding of squibs. They are there as a part of the background, like Filch, who is just a caretaker with a bitter attitude towards students because he can't do magic. In fanfic, though, squibs can be portrayed in a much more complex way. Some fanfics may show squibs as having a secret knowledge of the magical world that even some wizards don't have. Others might make them into heroes in their own right, using their non - magical skills in clever ways to solve problems in the magical world. Fanfic writers can really play with the concept, making squibs more than just the 'non - magical in a magical family' idea from the original series.
In the original series, squibs like Filch are more on the sidelines. But in fanfic, they can be the main focus. Fanfic might give them more agency and explore their unfulfilled magical desires more deeply.
In the original Harry Potter books, squibs are briefly introduced as an anomaly in the magical world. For instance, Filch is mainly shown as a grouchy caretaker. However, in fanfic, the concept of squibs can be expanded greatly. Fanfic authors may give squibs unique abilities that are not exactly magic but still useful in the magical world. They might also explore the emotional turmoil of a squib in a magical family in more detail, showing how they deal with the constant comparison to their magical relatives. Moreover, fanfics could create entire storylines around a squib's discovery of a way to gain a form of magic or their journey to find a place where they are accepted despite their lack of magic.
One way it can be different in fanfic is in the control aspect. In the original series, legilimency was a complex and somewhat restricted magic. But in fanfic, a character might have perfect control over their legilimency, being able to turn it on and off at will, or even target specific thoughts within a person's mind with great precision.
The power of augureys is often enhanced in fanfic. While in the books, their significance was somewhat limited. In fanfic, they might have the ability to heal with their feathers, or their song could have the power to put dark creatures to sleep. This expansion of their abilities makes them more interesting and central to the plot in many fan - created stories.
In the original books, Thestrals were not as prominently featured. But in fanfic, they can be the main focus. For instance, in some fanfic, Thestrals are shown to be more intelligent and able to communicate in ways not shown in the books.
His relationships can be changed. In the original, his interactions were somewhat limited. Fanfic authors might give him deeper friendships or romances. For instance, he could have a romantic relationship with a character that was not in his story arc in the original Naruto.
Fuuinjutsu in Naruto fanfic often has different levels of complexity compared to the original. Fanfic writers may introduce new types of seals that have unique properties not seen in the show. For instance, a seal that can transfer a person's soul into another body. Also, the power levels of existing fuuinjutsu might be exaggerated in fanfic to create more intense storylines.
In fanfiction, Dobby is often given more agency. In the original books, he is very much a servant - like figure at first. But in fanfictions, he can be a leader in the fight against the dark forces. For example, he might lead a group of house - elves in a rebellion against the Death Eaters who are cruel to them.
In the original books, goblins are mainly shown in relation to Gringotts Bank. But in fanfiction, they can have more diverse roles. They might be shown as having their own political agendas outside of the bank operations.
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.
His character arc can be very different. In the books, his development was somewhat limited, but in fanfiction, he could have a complete transformation. He might start to oppose the dark side more actively and become a hero - like figure, which is a big contrast to his original role.
In fanfiction, Fem Harry might be more in touch with her emotions. While the original Harry was often a bit stoic, Fem Harry could be shown as more openly expressing her fears and joys. For example, when she is chosen for the Triwizard Tournament, she might have a more emotional reaction like crying out of a mix of shock and anxiety.
