Well, Neville Longbottom is a great example. He was always a bit shy and clumsy before the war. But after the war, he's much more confident. He proved his courage during the battle and now he stands tall. Ginny Weasley has also changed. She was already strong - willed, but now she's even more determined. She wants to make a difference in the post - war wizarding world. And Draco Malfoy, he's more complex. He's trying to break away from his family's dark past and is more introspective.
Harry could develop a more peaceful side to his personality. He's seen enough death and destruction, so he focuses on promoting harmony in the wizarding world. Hermione may change in her approach to magic. Instead of just relying on book knowledge, she starts to experiment more, using her creativity. This change in their personalities can lead to new adventures and a different kind of relationship between them in fanfiction, whether it's a stronger friendship, a romantic relationship, or a partnership in making the wizarding world better.
In these crossovers, Harry Potter characters could develop a more cynical view of the world. Take Ron for example. In the Overlord - influenced story, he might lose some of his naivete and become more focused on self - preservation. The Overlord characters may also start to value things like friendship more, similar to how it is emphasized in the Harry Potter series, if they interact with the Potter characters long enough.
The characters in the harem often develop new traits related to their relationships. For instance, Luna, who is usually quite dreamy and detached in the original series, might become more grounded as she is part of Harry's harem. She has to be more involved in the practical aspects of their lives together, like helping to plan defenses against potential threats. Also, the relationships within the harem can bring out different sides of each character. They might show more jealousy or more selflessness depending on the situation, which is a significant change from their more one - dimensional personalities in the original books.
In such fanfiction, Hermione might become more outgoing like the High School Musical characters. She could start to participate in more social and musical events at Hogwarts, loosening up her typically studious nature. For example, she might join a choir or a dance group.
In many of these fanfictions, Hermione becomes more forgiving. After the war, she realizes that people can change, and she applies this to Draco. For example, in some stories, she doesn't hold his past actions against him as much as you might expect. Draco, on the other hand, often becomes more humble. He realizes the error of his ways and is trying to be a better person.
Hawkeye might become more serious. After seeing so much during the war, he could lose some of his carefree attitude. He might be more focused on making a real difference in the post - war world. Margaret, on the other hand, could become more empathetic. The war has shown her different sides of people, and she might be more understanding towards others.
Draco might become more humble. After experiencing the horrors of the war and the fall of his family's pure - blood ideology, he realizes the error of his ways. He becomes less arrogant and more open - minded. Hermione, on the other hand, could be more forgiving. She has seen so much death and destruction that she decides to let go of some of her past grudges, including those against Draco.
Hermione's personality might become more forgiving. After the war, she's seen so much death and destruction, and she might realize that even people like Draco can change. So she becomes more open - minded towards him. For Draco, he could become less arrogant. The war has humbled him, and being around Hermione, who doesn't tolerate his old - fashioned pure - blood superiority, forces him to reevaluate himself.
In these stories, Harry's usually brave and self - sacrificing personality might take on a more vulnerable side. He has to deal with the physical and emotional changes of pregnancy. Draco, who is often seen as cold and haughty, may become more empathetic. He starts to care for Harry in a way he never thought he would, which is a big change from his usual Slytherin self - centeredness.
In cold blood Harry Potter fanfics, Harry's personality might become more cynical. Instead of his usual hopeful and somewhat naive self, he could be distrustful of others. For example, he might suspect his friends of having ulterior motives more often.
