In such a fanfic, the plot could involve Harry finding a long - lost magical artifact that reveals his connection to Voldemort as his heir. As a result, he starts to have strange dreams and visions similar to what Voldemort had. The wizarding world would be in chaos as they try to figure out if Harry is going to turn to the dark side. Harry himself would be in a moral dilemma, trying to decide whether to embrace this new identity or fight against it.
One possible plot could be that Harry, initially shocked and confused, discovers his true parentage. Voldemort, instead of seeing Harry as an enemy, tries to groom him to be his heir. Harry might struggle with his new identity, having grown up believing he was an orphan with no relation to the Dark Lord. He could be torn between the values he learned at Hogwarts and the dark allure of his father's power. Eventually, he might use his unique position to try and change Voldemort's ways, or he could completely reject his father and fight against him in a new way, using his knowledge of Voldemort's weaknesses from their family connection.
One possible plot could be that Harry discovers the truth about his heritage as he gets older. This causes a huge upheaval in the wizarding world. His friends might be initially shocked and some might even turn against him. Harry then has to struggle to prove that he's not like Voldemort while also trying to understand his new - found identity.
For the Order of the Phoenix members, they would be in a state of shock. Lupin, for example, would be very concerned about Harry. He would try to talk to Harry, offer his support, but also be on guard. Ginny would be heartbroken. She loves Harry, but the thought of him being Voldemort's heir is terrifying. She would try to hold onto their relationship while also being afraid of what Harry might become. And the Death Eaters? They would be excited at first, thinking they have a new leader, but as they get to know Harry better, they might realize he's not as easy to manipulate as they thought.
Well, it could involve Voldemort having some strange newfound attraction to Harry and trying to make Harry his 'queen' in a very dark and twisted way. Maybe he uses dark magic to bind Harry to him and Harry has to find a way to break free.
One possibility is that the wizarding world would be in an even greater state of turmoil. The Order of the Phoenix might be suspicious of Harry, and the Death Eaters could try to manipulate him into joining their side. Harry would also have to deal with his own identity crisis, not knowing how much of his actions are his own and how much are influenced by his connection to Voldemort.
One possible plot could be that Harry tries to reason with Voldemort about the futility of his dark ways. He might talk about how much destruction Voldemort has caused and how many lives have been lost. Harry could also try to appeal to any remaining shred of humanity in Voldemort, perhaps by bringing up his own orphan status and how they both lost their parents in a way, though for very different reasons.
Maybe Harry has all of Voldemort's powers but uses them for good. He could start to look like Voldemort but with a kind heart, and he uses his new - found dark magic to fight off new threats that are even more powerful than Voldemort ever was.
In the 'harry joins voldemort fanfic', it could start with Harry being captured by Voldemort. Instead of killing him immediately, Voldemort decides to brainwash him. Through a series of dark magic spells and psychological manipulation, Harry starts to see Voldemort as a mentor. As time passes, Harry becomes an integral part of Voldemort's inner circle, helping him plan attacks against the wizarding world, believing that they are actually for a greater good as Voldemort has convinced him.
Well, one possibility could be that Voldemort adopts Harry as a way to control the wizarding world. He might think that by having Harry on his side, the resistance against him will crumble. Another could be that Voldemort discovers some sort of connection between him and Harry that makes him want to take Harry under his wing, perhaps related to some long - forgotten prophecy.
Yes, in certain fanfiction stories, Harry is depicted as Voldemort's heir. This might be because the authors want to explore a different kind of relationship between them. For example, they could use this concept to show how Harry has to struggle with an inner darkness that he inherits from Voldemort, which makes his character development more complex and interesting.
