Yes, there are some fanfictions with this concept. In the Harry Potter fandom, writers often explore alternative family relationships through fanfics. This particular idea of Sirius being Harry's dad can lead to some interesting storylines, like re - imagining how Harry's upbringing would have been different if Sirius had been his father from the start.
Sure. There are fanfics out there with that premise. It's a cool concept because Sirius was already like a father figure to Harry in the original series. In these fanfics, they can expand on that relationship and create new adventures and character developments based on the new family dynamic.
One common theme is family. Since Sirius is now Harry's dad, the fanfics often focus on building a strong family unit. Another theme could be redemption, as Sirius might have more of a chance to make up for his past mistakes. Also, there's the theme of protection, as Sirius would be even more determined to keep Harry safe from Voldemort.
It's also likely that they go to Romania. Given Sirius' knowledge of the wizarding world, he might know of a safe haven there. In Romania, they could be around dragons and learn about dragon - related magic. Harry would surely be fascinated by the dragons and it could be a place where he can grow stronger in a different kind of magical environment.
The relationship could also take a more complex turn. Other characters might get involved in their conflict. Some might side with Sirius, thinking Harry was in the wrong, while others might try to mediate. This outside influence could either help or hinder the mending of their relationship, depending on how it's handled in the fanfic.
Sirius might be shocked. He'd probably feel a mix of horror and protectiveness. He'd be horrified that Voldemort has used Harry in such a way and would be even more determined to keep Harry safe from Voldemort's clutches.
Well, Sirius is a very protective character. When he discovers that Harry is a Horcrux in the fanfic, he could initially be in denial. But once he accepts it, he'd likely start looking for ways to either protect Harry from Voldemort or find a way to remove the Horcrux part from Harry. He might also feel angry that Harry has been put in such a dangerous situation.
Sirius helps Harry become more confident. By sharing his knowledge and experiences, Harry feels more capable. For example, when Sirius teaches Harry a difficult spell, Harry realizes he can master things he thought were out of his reach.
In some darker fanfics, Sirius might be faking ignoring Harry as part of a plan to protect him from a greater threat. He thinks that by distancing himself from Harry, he can keep Harry out of danger. But of course, Harry doesn't understand this at first and is deeply hurt.
Sirius would probably be shocked at first. Then, he'd likely feel a deep sense of sadness and guilt. He might think that he should have been there more to protect Harry from getting those scars.
Maybe Harry is crying because he misses his parents. He often feels the pain of their absence deeply, and in this fanfic, when Sirius sees him, that could be the cause.
Yes, there are such fanfics in the Harry Potter fandom. Some fans like to explore different relationship dynamics and create unique storylines where Sirius and Remus are Harry's fathers in a romantic relationship. These fanfics often play with the idea of an alternative family structure for Harry within the magical world.
