In terms of relationships, 'giant growth' can have a significant impact. If Harry Potter were to experience giant growth, his relationship with Ginny might be affected. They would have to adapt to his new size. He might worry about accidentally hurting her. Also, his relationships with his friends could change as they now have to interact with him in a different way. Some might be in awe of his new stature, while others might be a bit intimidated.
Mentally, a character experiencing giant growth might feel isolated. If they become much larger than their peers, they could be seen as an outcast. In fanfiction, this could be explored as a character like Neville Longbottom grows large. He might struggle with self - esteem issues as he is no longer the same as the other students. However, it could also give him new confidence in some ways as he realizes his new physical power.
In some fanfictions, giant blood can amplify a character's magic. It might give them more raw power when casting spells. For instance, they could cast more powerful offensive spells compared to other wizards without giant blood. Their magic might also be more primal in nature, less refined but extremely forceful.
For Harry Potter himself, the living metal could present a new set of challenges and opportunities. He might have to learn how to control and utilize it, much like he had to learn about his own magic. It could also attract unwanted attention from dark wizards who are eager to get their hands on this unique material, putting Harry and his friends in danger.
It can limit their physical abilities. For instance, a character with heart disease might not be able to participate in strenuous magical activities like Quidditch. They may also be more vulnerable to dark magic attacks as their weakened state makes it harder for them to defend themselves magically. In some fanfictions, it could lead to social isolation as other characters might avoid them out of fear that the disease is contagious or that they are a liability.
The limbo can force characters to confront their inner demons. For Harry, it might be his fear of not being able to save everyone. This self - realization can lead to him becoming more determined and stronger. Characters may also discover new powers or abilities in the limbo. Hermione, for example, could find that her intelligence takes on a whole new form in this strange realm, which then helps her in her future adventures outside the limbo.
The return of the dead can also cause conflict among the characters. Some might be skeptical or even afraid of the resurrected character. They could think it's some sort of dark magic at play. Take Hermione for instance. She might be initially cautious and want to investigate how and why the character has returned, which could lead to tension within the group of friends.
It can enhance their magical abilities. If two characters are Soul Bonded, they might be able to combine their magic in a more powerful way. For example, they could cast spells that are far beyond their individual capabilities.
The purity potion can also create conflict between characters. For instance, if one character passes the test and another fails, it could lead to jealousy or discrimination. This can drive the plot forward as characters deal with the fallout of these results. In some fanfictions, a character who fails the purity potion test might be ostracized by their community, which forces them to either fight to regain their standing or find a new place where they are accepted.
One interesting scenario could be a character like Hagrid accidentally casting a giant growth spell on himself. He's already large, but this could make him truly gigantic, towering over the Hogwarts castle. It might lead to some comical situations as he tries to navigate through the narrow corridors and small rooms in the castle.
The Weasley family would have mixed reactions. Mrs. Weasley would probably still try to mother Harry, even though he's emancipated. The younger Weasley siblings might look up to Harry even more, seeing him as a truly independent and brave figure. While some of the older Weasleys might be concerned about the implications of Harry's emancipation on the wizarding world's social order.
It can change the perception quite a bit. For example, if Ron is made to betray Harry in fanfiction, readers might start to question the loyalty that was so fundamental to Ron's character in the original books. It makes the character seem more complex and perhaps less reliable.
