One consequence could be that his connection to Voldemort becomes even stronger. This might lead to him being able to sense Voldemort's actions and thoughts more clearly, but also make him more vulnerable to Voldemort's attacks on his mind. Since the Horcrux is a part of Voldemort's soul, it could also start to influence Harry's personality, making him more aggressive or moody at times.
Another aspect is that the magical community might view him differently. Some may fear that he is now tainted by the dark magic of the Horcrux. His friends, on the other hand, would be worried about him and try to help him. Harry himself would have to find a way to either get rid of the influence of the Horcrux or learn to control it. This could involve seeking out powerful magic or ancient spells to cleanse himself, and it would be a long and difficult journey for him.
If Harry were to create a Horcrux in fanfiction, it would likely lead to a great corruption of his soul. Horcruxes are dark magic, and the act goes against all that Harry stands for in the original series. He might start to show signs of increased aggression, a detachment from his friends, and a growing attraction to the Dark Arts.
In some fanfictions, when Harry absorbs the Horcrux, it could lead to a moral dilemma within him. He has to struggle with the dark influence of the Horcrux while still trying to be the good wizard he is. This internal conflict can make for a really engaging story, with Harry constantly fighting his inner demons and trying to separate his own identity from that of Voldemort's.
One consequence could be that Harry feels an internal struggle. Since he has a part of Voldemort's soul in him, he might have to constantly fight against the dark impulses that come with it. For example, he may find himself having more aggressive thoughts or being more easily influenced by dark magic in certain situations.
Yes, in some fanfiction, Harry Potter is considered a Horcrux. This concept adds an interesting twist to the original story, exploring different aspects of magic and the connection between Harry and Voldemort.
If Harry Potter makes a Horcrux in fanfiction, it would be a major departure from his character. Horcruxes are dark magic, and Harry is firmly on the side of good. One consequence could be that he starts to be corrupted by the dark magic within the Horcrux. His friends might turn against him as they see him slipping into darkness. He could also lose his connection to the positive magic that has always defined him, like his ability to use the Patronus charm.
Perhaps his father's old wand. It has a connection to his family and his heritage. Since it's a wand, it already has a certain amount of magical energy, so it could potentially be a suitable vessel for a Horcrux. And it would be a very interesting twist on the concept of a Horcrux as wands are not a typical choice.
Well, in some fanfictions, a Horcrux might be purified through powerful magic spells that are specifically created for the purpose. For example, a spell that can reverse the dark magic used to create the Horcrux in the first place.
Well, it could be that Dumbledore, in some fanfic versions, figures it out first and then reveals it to Harry. Dumbledore is often portrayed as having a deep understanding of magic. He might have noticed some strange magical patterns or behaviors related to Harry that led him to suspect and then confirm that Harry was a Horcrux. And then he would tell Harry about it, which is how Harry comes to know.
His personality could change quite a bit. The Horcrux's dark energy could make him more aggressive at times. He may also develop a sense of superiority due to the extra power, but also have moments of self - loathing when he realizes the source of that power is dark.
One implication is a deeper connection between Harry and Voldemort. Their fates are even more intertwined than in the original story.
