How does the 'snape is harry's father fanfiction' change the overall story of Harry Potter?

The 'Snape kills Harry' fanfiction would shatter the relationships that were built in the original series. For example, the friendship between Harry, Ron, and Hermione would be left in tatters. Hermione and Ron would be devastated and likely seek revenge. Also, Dumbledore's plan, whatever it was that involved Harry, would be completely ruined. The whole balance of good and evil in the wizarding world would be thrown into chaos.

Well, it completely flips the dynamic. In the original series, Snape was a complex character with a lot of hidden motives that were ultimately revealed to be on the side of good. If Harry kills Snape in the fanfic, it makes Harry seem more impulsive and less of the heroic figure we know. It also undermines the redemption arc that Snape had in the original story.

The relationships that Harry was supposed to form later in life, like his friendships with Ron and Hermione, would never happen. And the whole wizarding world would be different. Without Harry, there might not be someone to stand up to Voldemort in the same way. So, the power balance in the wizarding world would be completely shifted. Also, the mystery around Harry's scar and his connection to Voldemort would be left unresolved in a way that leaves the story with a sense of incompleteness.

This changes the story dynamics massively. In the original story, Snape was a mystery and an antagonist of sorts to Harry. But if he's Harry's father in a fanfic, it means that Snape's actions were not just out of some old grudge or loyalty to Dumbledore. His protectiveness towards Harry could be seen as a fatherly instinct. It also changes how we view Lily's relationship with both Snape and James. Maybe there was more to the story than we knew, and Snape had a closer connection to Harry all along that was hidden for some reason.

In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.

Well, it makes the story much more complex. Instead of being a double agent against Voldemort, Snape is now on his side. This could lead to a much darker and more dangerous situation for the good guys. For example, Harry and his friends would have a harder time getting information or help from Snape.

The overall plot would be completely different. Since Harry is Rias's father, he might introduce some Hogwarts - like education into the Underworld. This could lead to a new generation of devils with different skills and values. Harry's past traumas might also make him extremely protective of Rias, and this could lead to conflicts with other devil families who have different ideas about Rias's role in the Underworld.

Well, it completely flips the script. Instead of being the hero, Harry is now a criminal. This changes the way we view the other characters too. For example, the relationship between Harry and Dumbledore might be seen in a different light. Dumbledore's guidance might be seen as either misguiding Harry into criminal behavior or as an attempt to control a potential criminal.

It can lead to a completely different dynamic. Harry might have a new perspective on Snape and the magical world.

It changes the story a great deal. Firstly, the gender change means different social expectations within the wizarding world. Female characters often face different challenges and opportunities. Also, being reborn as a Black alters the power dynamics. The Blacks are an old and influential family, so she has a different kind of influence and access to resources. For example, she may have more influence in Slytherin house which was often associated with the Blacks.
