In some fanfictions, Severus is indeed made out to be Harry's biological father. Fanfiction allows for a lot of creative reinterpretation of the original story. Writers might do this to explore different character dynamics and add new layers of drama and relationships to the Harry Potter universe.
There are many fanfictions that explore Severus Snape's father. Some might depict him as a cruel man who had a negative impact on Snape's childhood. In some fanfictions, he could be an absent figure, which might have contributed to Snape's rather solitary and often bitter nature.
Yes, there are such fanfictions in the Harry Potter fandom. Some fans like to explore this alternative family relationship through their creative writing.
One consequence is a change in Harry's self - identity. He would have to reevaluate who he is in relation to Severus. Also, the relationship between Harry and the other characters, like James Potter (who was originally his father), would need to be reimagined.
In fanfiction, anything can be reimagined. It could be possible through creative plot devices like a hidden relationship between Snape and Lily Potter before she was with James. Maybe there was a secret encounter that led to Harry's conception, and the truth was hidden all along.
In fanfic, making Severus Snape Harry Potter's father can be a really interesting concept. It often changes the whole dynamic of the story. For example, Snape's relationship with Harry would be completely different. Instead of the animosity we see in the original books, there could be a more complex father - son relationship filled with Snape's typical brooding and Harry's confusion but also a sense of connection. Fanfic writers might explore how Snape could have hidden this fact and what his reasons were for doing so. It also might change how Harry views magic, as he would be the son of one of the most complex and talented wizards in Hogwarts.
One possible plotline could be that Snape initially hides his relationship to Harry out of fear or a sense of duty. He might secretly protect Harry more than anyone realizes. For example, his constant bickering with Harry could be a way to hide his true feelings. Another aspect could be how Harry discovers the truth. Maybe he finds some old letters or a hidden memory in Snape's Pensieve. This revelation would completely change Harry's perception of Snape and his own identity. It could also lead to a complex relationship between Harry and his mother's memory, as he would have to reconcile Snape's role in her life with his newfound knowledge of Snape as his father.
In some fanfictions, Severus Snape being Harry Potter's father is a radical but interesting concept. It often involves re - imagining the relationship between Lily and Snape. Maybe there was a hidden, deeper connection between them that led to Harry's birth. This changes the whole dynamic of the story as Snape would then have a more personal stake in Harry's life from the start.
Sure. Some fanfics might give Snape's father a more sympathetic portrayal. Maybe his father was caught up in some dark magic against his will, and this had consequences for Snape's family. These types of fanfics can be really interesting as they often rewrite the known facts about Snape's family in a creative way, making us see Snape from a different perspective.
One common theme is redemption. Snape was often portrayed as a complex and somewhat villainous character in the original series. In these fanfictions, being Harry's father gives him a chance to redeem himself in a more direct way. Another theme is family secrets. There are often a lot of secrets about how Snape and Lily got together and how Harry's true parentage was hidden.
