Well, in fanfiction, Draco's arrogance from the books can be toned down a bit. He could be shown as secretly having a good heart all along. His snobbishness might be a front that he drops more quickly. Hermione's perfectionist streak can be exaggerated in some fanfictions. She might be even more obsessed with her studies and magic, but also more likely to let her guard down around Draco. And in fanfiction, their mutual understanding of each other's situations can be explored more deeply. For instance, Draco understanding Hermione's plight as a Muggle - born in a prejudiced wizarding world, and Hermione understanding Draco's family pressures.
In some fanfictions, Draco may be portrayed as more open - minded and less of a bully. He might show a softer side earlier on when working with Hermione. For example, instead of immediately making snide remarks, he tries to have a civil conversation. Hermione, on the other hand, could be more patient. In the original books, she was quick to judge Draco, but in fanfiction, she might give him more of a chance, seeing the potential good in him.
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.
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 some fanfictions, Johanna's loyalty to her friends, especially Haymitch, is made into a central part of her personality. She is shown as being extremely protective of him, which is a bit different from the books where their relationship was more complex. Haymitch in fanfiction may be more proactive in trying to change the system. In the original, he was more resigned to the Capitol's rule until Katniss came along. Here, he could be constantly looking for ways to undermine the Capitol, and Johanna could be his partner in this endeavor.
Well, when it comes to Hermione in fanfiction, she could be given new magical abilities or be involved in more complex relationships. Snape might be depicted as having a more sympathetic backstory, perhaps with a secret friendship with Hermione. Lucius, on the other hand, may be redeemed in some fanfictions, which is very different from his mostly villainous role in the books. The fanfiction world allows for a great deal of experimentation with these well - known characters.
In some fanfictions, Naruto might be more assertive in his feelings towards Gaara compared to the original anime where their relationship is more about friendship. Gaara may be shown as more vulnerable when it comes to love, as in the anime he is often portrayed as stoic and strong.
In fanfiction, Naruto might be portrayed as more emotionally vulnerable around Sasuke. In the original series, he was always very boisterous and positive, but in fanfiction about their brotherly relationship, he could show his insecurities to Sasuke more openly. For example, he might talk about his fear of not being good enough as Hokage. Sasuke, on the other hand, could be shown as more patient. In the original, he was often brooding and impatient, but here he listens attentively to Naruto's concerns.
In some fanfictions, Naruto's childhood self can be even more naive and innocent compared to the original. He might be more openly vulnerable about his feelings of loneliness. For example, he could cry more easily when Sakura accidentally says something that hurts his feelings. Sakura, on the other hand, may be portrayed as more motherly towards Naruto in her childhood in fanfictions. In the original, she was mainly focused on Sasuke, but in fanfiction, she might be the one to comfort Naruto more often.
In the fanfiction, Loki might be more vulnerable. Since he's getting married, he could show a side of himself that is more open to love and less of the mischievous trickster. For example, he may be more hesitant to play pranks that could potentially harm Jane's feelings.
In the fanfiction, Evil Naruto might be more cynical and power - hungry. He could have lost his belief in the values of the Hidden Leaf. Gaara, on the other hand, might be more cold - hearted and less likely to show any mercy, as opposed to his more complex and evolving personality in the original series.
