This revelation would likely shatter Harry's previous idealized view of his father. He might start to question all the stories he had been told. For example, if he was told his father was a hero, now he has to grapple with the fact that he was a bully. It could make Harry feel conflicted, angry, or even a bit lost. He may wonder if he has any of those bullying tendencies in him too.
His friends might be shocked too. They could be supportive of Harry, trying to help him come to terms with this new information. For example, Hermione would probably start researching if there was any way to change this in the magical world's past, while Ron would be more about just being there for Harry, sharing his feelings.
If Harry finds out Severus is his father in fan fiction, it could completely change the dynamic between them. Harry's view of Severus would shift from hatred or suspicion to a complex mix of emotions. He might start to understand Severus' actions in a new light, like his seeming animosity towards Harry in the original story could be reinterpreted as a father's tough love. This revelation could also change Harry's relationship with the other characters. For example, his connection to the Snape family, if there are any in the fan - made lore, would become significant. It could also impact how he views his mother, Lily, and her relationship with Severus.
One interesting plot could be Harry's struggle to accept Severus as his father. He has such a long - held image of Severus as an enemy, and now he has to come to terms with this new reality. Another plot could be Severus trying to make up for lost time and be a good father to Harry. There might also be a plot where the wizarding world reacts to this news. Some might be shocked, others might not believe it at all.
Harry's character grows in terms of self - confidence. Knowing that Sirius is his father gives him a stronger sense of identity. He no longer feels like an orphan in the truest sense. He becomes more assertive in the wizarding world, demanding respect and answers. For example, he might be more forceful in his interactions with Snape, not tolerating any slights as he now has a powerful family connection.
One interesting plot development could be how Harry's relationship with the wizarding world changes. Knowing Sirius is his father might make him feel more confident and entitled to certain things. He might demand more answers from Dumbledore about his family's past and the secrets that were kept from him. Another aspect could be his relationship with the Weasleys. It might become a bit strained as he realizes his true lineage and starts to see himself in a different light, perhaps more of a pure - blood heir in his own mind, which could contrast with the Weasleys' more humble status.
A unique concept makes it stand out. For example, if the soulmate is not a typical witch or wizard but has some special power or origin. Also, good character development is key. If the author can show how Harry and his soulmate grow both as individuals and as a couple. It should also fit well within the existing Harry Potter universe, respecting the lore and the established characters' personalities.
In this kind of fanfiction scenario, it would be a huge shock for Harry. He would probably struggle with a whole new set of emotions. His relationship with Ginny, which was romantic before, would have to be completely re - evaluated. He might feel a sense of betrayal, not towards Ginny but towards the situation. He would also have to deal with how this new knowledge affects his relationships with the Weasley family. For example, he might feel odd about his connection with Ron, who is now also Ginny's brother.
Well, often in fanfiction, when Harry discovers his inheritance, it can completely change his social standing. He could be revealed as part of an ancient and noble magical family. This might lead to him getting more respect from the wizarding community and also open up new opportunities for him in terms of education and alliances. For example, he could be given access to rare magical libraries or training from the most skilled wizards in the family. He might also find out about family secrets that have been hidden for generations, which could help him in his fight against Voldemort or other threats.
In such a fanfiction, Harry would likely be in shock. His world view has been centered around their deaths for so long. He could be hesitant to trust this new reality. But once he does, he'd have a whole new support system. His parents could teach him magic they've learned in their 'hidden' years. This would make him even more powerful and give him a different standing among his peers.
