In some fanfictions, Molly Weasley might be portrayed as more of a mentor figure to characters other than her own children. For example, she could be shown guiding Harry through some complex magic that even Dumbledore hadn't thought of. This is different from the original series where her focus was mainly on her family and the Order's activities within that family - centric context.
Often, fanfiction writers give Molly a more adventurous side. Maybe she goes on secret missions alone, which is a departure from the books where she was mostly at home taking care of things. She could be depicted as a powerful witch in combat situations in fanfiction, using her skills not just for protection at home but in the wider wizarding world battles.
A living Lily in fanfiction might be depicted with a different personality. In the original story, we mainly see her through memories, but in fanfiction, she can be given new traits. She could be more assertive or more involved in political aspects of the wizarding world. For instance, she might take a stand on issues like blood purity in a more direct way than she could in the original plot, which was cut short by her death.
In these fanfictions, Draco may be shown as a more vulnerable character. His marriage to Harry makes him show his softer side that was hidden in the original series. Harry might be portrayed as more confident in his choices outside of just fighting Voldemort. His relationship with Draco gives him a new kind of strength and stability, and he becomes more of a relationship - builder in the fanfic world.
Well, in the original Harry Potter series, Harry was focused on fighting Voldemort and his adventures were mainly centered around that. However, in this fanfiction, since Fem Harry is Bill's mate, their relationship would develop with a focus on building a life together. Their relationship might develop through shared interests in things like exploring different parts of the wizarding world that are not related to the main battle. And the way they communicate would be different. Fem Harry might be more open about her emotions with Bill compared to the original Harry who was often more reserved. Also, their relationship would be influenced by the Weasley family traditions and values in a much deeper way as they are mates, not just friends or comrades.
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.
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 relationship could start with mutual respect. Harry has always respected Molly as a mother figure in the Weasley family. This could gradually turn into something more romantic as they share more personal experiences. For example, Harry might confide in Molly about his post - war traumas, and Molly's understanding and care could lead to deeper feelings.
There are also fanfictions about Molly Weasley's friendship with other characters. She could be shown interacting with the other members of the Order of the Phoenix. Her no - nonsense attitude and motherly instincts might come into play in these relationships. For instance, she might be the one to comfort or give advice to her friends in the Order during the fight against Voldemort, showing her importance not just within her family but also in the broader fight for good in the wizarding world.
In the fanfiction, their relationship would be much more intense and instinctive. Instead of just being friends or acquaintances as in the original series, they would have an unspoken connection. For example, they might be able to sense each other's emotions from a distance. If Bill was in danger while on a mission far away, Harry would feel a sense of unease or even pain without really knowing why at first. Their relationship would also involve a lot more secrecy because it's not a normal type of relationship in the wizarding world.
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.
