Yes, there are likely some fanfictions out there with this concept. Fanfiction often takes creative liberties with established universes, and making Regulus Black Harry's father is an interesting and non - canonical twist. Writers might explore how this would change Harry's story, his relationships, and the whole wizarding world's dynamic.
One possible plotline could be that Regulus faked his death earlier than in the original story. He could have had a relationship with Lily Potter secretly. Then, when Voldemort targeted Harry, Regulus would have to come out of hiding to protect his son. Another plotline might involve Regulus being a double agent for the Order of the Phoenix all along, and his relationship with Lily was part of a bigger plan to protect the wizarding world from Voldemort, with Harry being an unexpected but important part of that plan.
Fanfiction about these three can take many forms. For example, there could be time - travel fics where Harry goes back in time and meets Regulus and Sirius when they were younger. This could lead to all sorts of interesting plot twists, like Harry trying to prevent Regulus from joining the Death Eaters in the first place. Or it could be a fic where Sirius survives and he and Harry explore the secrets of the Black family together, including things that Regulus left behind. There are also fics that focus on the emotional bonds between the characters, showing how the different personalities of Regulus, Sirius, and Harry interact and influence each other.
Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often come up with creative and alternative family relationships for characters. They might explore how Hermione's story could be different if Regulus were her father, perhaps delving into how her magical abilities or her place in the wizarding world might be affected by this new family connection.
It's popular because it combines two very interesting characters. Harry is the main hero of the series, and Regulus is a mysterious figure with a complex backstory. Writers can explore what could have happened if they had interacted more directly.
One common theme is redemption. Regulus is often depicted as seeking redemption for his past mistakes, and Harry can be a catalyst for that. Another theme is family secrets. Since both are part of complex wizarding families, there are always secrets to uncover.
One common theme is redemption. Since Regulus was once part of the Death Eaters and then turned against Voldemort, many fanfictions focus on his journey to make up for his past mistakes. Another theme is family secrets. The Black family has a lot of hidden history, and fanfictions often explore how Regulus was affected by these secrets and how he dealt with them in relation to Harry Potter's story.
One interesting fanfiction could be 'The Lost Black'. In it, the daughter of Regulus Black plays a crucial role in uncovering some long - forgotten secrets in the wizarding world. She teams up with Harry Potter and they go on an adventure that spans from the hidden corners of Hogwarts to the dangerous Forbidden Forest.
The story would also shift in terms of Harry's place at Hogwarts. His sorting into Gryffindor might be more complex. Since he's related to the Black family, which has a history of being in Slytherin, there could be an internal struggle within Harry about his house loyalty. And his friends, like Ron and Hermione, might react differently to this new revelation about his parentage as they've always known him as a Potter.
One interesting fanfiction could be about Regulus Black's secret adventures during his time at Hogwarts that were not mentioned in the original books. It might explore his relationships with other Slytherins in more depth, and how he really felt about the Dark Lord's rising power.
A really interesting fanfiction is the one that explores Regulus Black's connection to the Marauders through Harry. It's set in a post - Voldemort world where Harry discovers some long - lost journals of Regulus. These journals open up a whole new perspective on the relationship between the Blacks, the Marauders and Harry's own family history. It's full of mystery and revelations that keep you hooked till the end.
