Often, fanfic authors give Cho a more complex backstory. Maybe she has family secrets related to the wizarding world's history. This can lead to her making different choices. For instance, she could be more involved in the Order of Phoenix's activities earlier on, rather than just being on the sidelines as in the original. This new backstory can also affect her relationships with other characters, like her friendship with Hermione or her rivalry with Ginny in a more nuanced way.
Well, in certain fanfictions, Cho is depicted as being more independent. She might not be as hung up on Cedric's death as in the books. Instead, she uses that as motivation to become stronger. She could be traveling the wizarding world, learning new spells and making new alliances. This makes her a more well - rounded character compared to her somewhat one - dimensional portrayal in the original series.
Some characters might develop new skills. For instance, Hermione could learn a type of magic from another universe that makes her even more powerful. This would change her role in the story and how others interact with her.
In the fanfiction, Snape might be developed with more of a sense of humor. For example, in the original series, he is very dour, but in the fanfiction, his interactions with Harry in the context of a risky business situation could bring out a side of him that cracks jokes or uses sarcasm in a more light - hearted way. This would be a big departure from his usually serious self in the books.
She could be more introverted compared to Harry. While Harry is often thrust into the spotlight, the little sister could be someone who prefers to stay in the background, observing and learning. This would make her a bit of an enigma to the other characters at Hogwarts, and her actions might be more calculated and less impulsive.
Well, in some fanfictions, Harry's relationship with werewolves could be explored in a much deeper way. He might develop a more empathetic side towards them, especially if he meets a werewolf who is not as bloodthirsty as the ones he has encountered before. Hermione could be developed to be more of a risk - taker. When it comes to werewolves, she might be willing to put herself in more dangerous situations to study them or help them, which is different from her usually cautious self in the original series.
In some 'James Potter alive' fanfictions, his character can be more mature. For example, if he comes back after a long time, he might have learned from his past mistakes. In the original, we saw him as a bit of a troublemaker in his youth. But in fanfics, he could be more responsible, especially if he realizes he has a second chance to be a better father to Harry or a better friend to his mates. He might also be more empathetic, having seen the consequences of his actions (or rather, his 'death') on those he left behind.
In such fanfictions, Hermione as a Time Lady could have her character development centered around her newfound abilities related to time. For example, she may struggle with the ethical implications of time travel and changing events. This is different from the original Hermione who was mainly focused on the study and practice of magic within the Hogwarts framework. Her relationships might also change. She could be more distanced from her friends at first as she tries to understand and control her new powers.
In fanfiction, Harry might be more worldly. Since he gets more exposure to Viktor and Durmstrang, he could pick up on different magical traditions faster. For example, he might start using some Bulgarian hexes in his duels. Viktor, on the other hand, could be shown to be more open - minded. In the books, he was a bit reserved. In fanfiction, he could be more eager to learn about Hogwarts' ways and make more friends there.
Well, in fanfiction, Severus' character can be developed to show his softer side towards Lily earlier on. In the books, we mainly see his tough exterior and his actions as a double agent. But in fanfiction, we might see him expressing his love for Lily in more open and desperate ways. As for Lily, she could be developed in a way that she is more empathetic towards Severus' situation. In the books, she seemed to cut him off quite harshly, but in fanfiction, she might try to understand his reasons for getting involved with the Death Eaters and still hold some hope for their relationship.
Well, in the original Harry Potter, Harry is male and has certain male - oriented experiences. As Fem Harry in Fairy Tail, she would face different challenges related to being a female in a new and different magical world. For instance, she might have to deal with different expectations from the Fairy Tail guild members regarding her appearance or how a female mage should act.
In these fanfictions, Hermione could be more fearless in the face of werewolf - related danger. In the original, she was mainly focused on academic and general wizarding world problems. But here, she might be more hands - on with werewolf matters, using her intelligence to solve problems specific to the werewolf community. For example, she could be researching new spells to help werewolves control their transformations, which shows a different side of her problem - solving skills.
