Sirius Black wants Harry fanfiction: What are some popular plotlines in such fanfictions?

A possible plotline could be that they start to investigate the true history of the Black family. As they dig deeper, they find out secrets that could change the course of the wizarding world. They might also use their status as Lords of the Black family to form new alliances. For example, they could reach out to other families that were previously at odds with the Blacks. This would not only strengthen their position but also help in the fight against the forces of evil. Along the way, they would have to deal with their own personal growth and how being part of the Black family affects their identities, especially Harry, who has always been an orphan with no real family until now.

One interesting plotline could be a mystery - solving one. Harry discovers some strange artifacts in Grimmauld Place that were left by Regulus. With Sirius (if he's alive in the fic), they try to figure out what these artifacts mean and it leads them to uncover a long - forgotten plot by Voldemort. Another plotline could be a redemption arc for Regulus. Harry, after learning about Regulus's attempts to undermine Voldemort, tries to clear his name in the wizarding world, which causes some friction with those who still see the Black family as mostly dark wizards. And there could be a plotline about family secrets. Sirius and Harry find out that there are hidden magical abilities in the Black family bloodline that only Regulus knew about, and they have to figure out how to use or control them.

One common plotline could be Sirius teaching Harry more about his family's history in a way Dumbledore didn't. For example, Sirius might share hidden secrets about the Potter family magic that Harry was never aware of.

One common theme is Sirius as a father figure to Harry. Since Harry lost his parents early, Sirius can fill that role in fanfictions, guiding Harry and protecting him.

Some fanfictions explore the idea of Hermione being sorted into Slytherin instead of Gryffindor. This changes their relationship as they are in the same house. It can lead to them becoming friends or rivals in a different way than in the original series, and often there are complex relationships that develop between them over time.

One common plotline is Sirius being protective of Hermione. He might see her intelligence and bravery and feel drawn to her. He could protect her from various threats in the wizarding world, like Death Eaters or other dark forces.

One common plotline is Sirius Black escaping from Azkaban earlier and secretly training Harry in advanced magic. Another could be Sirius and Harry going on a hidden adventure to uncover more about Harry's parents. There are also stories where Sirius plays a more active role in the fight against Voldemort at Hogwarts, using his knowledge of the Dark Arts and his Animagus form to their advantage.

One popular story is 'The Unspoken Bond' which delves deep into Harry's longing for Sirius's presence and guidance. Another is 'Sirius's Return' where there are some really interesting plot twists around Harry's desire to have Sirius back. You can find these on Archive of Our Own.

One popular Sirius Black OC fanfiction could be 'The Lost Heir of Black'. It has an interesting plot where the OC is a long - lost relative of the Black family with unique magical abilities. Another one might be 'Sirius and the Mysterious Newcomer' which focuses on how an OC disrupts Sirius's life in an unexpected way. There's also 'Black Family Redemption' where an OC plays a crucial role in helping Sirius and the Black family regain their honor.

Another plot is a sort of forbidden love story. Given their different allegiances in the original series, a fanfiction might explore how Hermione and Lucius overcome their differences and fall in love. It could involve a lot of tension, secrecy, and internal conflict as they deal with their feelings and the reactions of the wizarding community.
