They're interesting because it's a unique twist on the original Harry Potter story. It adds a whole new layer of complexity to Harry's character. Instead of just fighting against Horcruxes, he has to deal with being a part of that dark magic in a way.
One popular 'Harry absorbs Horcrux' fanfiction might be 'The Horcrux Within'. It delves into how Harry's character changes as he absorbs the Horcrux. The story explores his internal struggles and how it affects his relationships with his friends at Hogwarts. Another could be 'Absorbing the Darkness' which focuses on the magical implications of such an event. It shows how Harry has to learn to control the new power within him that comes with the absorbed Horcrux.
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.
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.
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.
It can completely change the direction of the plot. For instance, if Harry absorbs the Horcrux early on, he may have to face different challenges than in the original story. He might become a target for both sides, as the good side could be wary of his new, Horcrux - influenced state, and the bad side might see him as a threat to Voldemort's power.
Well, it might enhance his abilities in some ways. Since a Horcrux contains a part of a powerful dark wizard's soul, absorbing it could potentially give Harry access to some dark magic knowledge or powers, though it would also likely be a dangerous and unstable influence on his magic.
Yes. In the Harry Potter fandom, the concept of Harry being a Horcrux is quite a popular and fascinating one for fanfic writers. It adds a whole new layer of complexity to the story and character relationships.
In fanfic, it could be through a dark spell gone wrong. Maybe a spell that was meant to destroy the Horcrux instead backfired and caused it to merge with Harry.
In a 'harry potter and the last horcrux fanfic', it may center around the significance of the last Horcrux. It could depict the emotional and mental state of Harry as he approaches the end of his long journey. There could be unexpected twists, like the Horcrux being hidden in a place no one suspected. It might also expand on the lore of Horcruxes, for example, by showing different ways to detect or destroy them that were not mentioned in the original series.
