Often in fanfiction, Draco's insecurities are more on the surface when he's with Hermione. He may worry more about how she perceives him, which is different from the books where he mostly hid his insecurities behind his bravado. Hermione's personality can be tweaked to be more empathetic towards Draco. She realizes that his upbringing in a strict pure - blood family has influenced his actions, and she tries to help him break free from some of those constraints, which is a departure from her more judgmental stance in the original story.
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.
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 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.
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.
In some fanfics, Harry might be more open - minded towards Luna's eccentricities compared to in the books. He could be shown to fully embrace her ideas right away instead of gradually coming to respect them. Luna, on the other hand, might be made even more confident in her beliefs and actions. For example, she could be more assertive in standing up for her views on magical creatures, like the Crumple - Horned Snorkacks.
In some fanfictions, Nami might be portrayed as more assertive towards Zoro. For example, she could be the one who always initiates their adventures together, whereas in the original series, it's often a more collective decision. Zoro, on the other hand, may be shown as more patient with Nami's sometimes - bossy attitude, which is a contrast to his more straightforward and tough - guy image in the original.
In fanfiction, Naruto might be portrayed as more vulnerable in his relationship with Itachi. In the original series, he is very boisterous and confident, but in yaoi fanfiction, his feelings for Itachi could make him more hesitant and self - conscious. For example, when expressing his love, he might stutter or blush more often.
Well, in chibi fanfiction, Naruto is often depicted as an even more energetic ball of sunshine. His love for ramen might be shown in a cuter, more obsessive way. Sasuke, though still having his serious demeanor, may be more approachable. His determination to become stronger could be intertwined with his friendship with Naruto in a more light - hearted manner. For instance, instead of the deep - seated angst in the original, his drive to be better might be because he wants to keep up with Naruto's growth in a friendly way.
