What are the possible consequences for Harry in the fanfic where Sirius learns that Harry is a Horcrux?

Sirius might be shocked. He'd probably feel a mix of horror and protectiveness. He'd be horrified that Voldemort has used Harry in such a way and would be even more determined to keep Harry safe from Voldemort's clutches.

Well, Sirius is a very protective character. When he discovers that Harry is a Horcrux in the fanfic, he could initially be in denial. But once he accepts it, he'd likely start looking for ways to either protect Harry from Voldemort or find a way to remove the Horcrux part from Harry. He might also feel angry that Harry has been put in such a dangerous situation.

One implication is that Harry's life is in even more danger. Voldemort might be more determined to keep him alive until he can fully use Harry for his own evil purposes.

In this kind of fanfiction, it often shows Ginny's shock and the complex emotions she might have. She might be worried about Harry's fate, as being a Horcrux means he is tied to Voldemort in a very dangerous way. This discovery could lead to her trying to find a way to break the Horcrux connection without harming Harry.

Well, it depends on how the author writes it. Maybe Voldemort would initially be in disbelief. But once he accepts it, he could start to manipulate Harry in different ways. He might think that by controlling Harry, he can control the Horcrux within him. This could create some really interesting plot twists where Harry has to resist Voldemort's attempts at a much deeper level than just physical attacks.

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.

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.

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 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.

The theme of self - discovery for Ginny is often seen. As she delves deeper into the situation of Harry being a Horcrux, she might discover new aspects of herself, like her own strength in dealing with such a complex and dangerous situation. And there's also the theme of hope, that despite the seemingly impossible situation, there is always a way to save Harry and defeat Voldemort.
