What are some common plot devices in fanfiction about Sirius Black joining Voldemort?

It's possible in fanfiction, but it would be a huge departure from his character. Sirius Black is a Gryffindor, known for their courage and loyalty to the side of good. He has personal reasons to hate Voldemort, like the death of his friends at the hands of the Death Eaters. But fanfiction authors might create a complex backstory to justify his joining. Maybe they could write that he was under a powerful spell or was tricked into believing Voldemort had different intentions. Still, it would shock most fans who know the original Sirius.

Another aspect could be the relationship development. The kidnapped character and Sirius might start off as enemies or strangers, but through the events of the kidnapping, they come to understand each other better. There could be a lot of tension and conflict at first, but as they interact more, a bond forms.

One possible fanfiction could be about Sirius Black being in a situation where he has to face Voldemort alone. Maybe he discovers a secret weakness of Voldemort that no one else knows. Sirius, with his brave and reckless nature, decides to take advantage of this knowledge to try and take down the Dark Lord once and for all.

A fanfiction could center around Sirius Black's attempts to rescue someone from Voldemort's clutches. He uses his skills as an Animagus and his knowledge of the wizarding world's hidden paths to get close to Voldemort's lair.

One common plot device is the discovery of a hidden letter or prophecy that reveals the relationship. Another is a magical bond that starts to surface between Snape and Voldemort as the story progresses. Also, there might be a plot where Snape has to struggle with his new - found identity and his loyalty to Dumbledore.

Another plot device could be the revelation of a long - lost prophecy or a secret document. This prophecy or document might have the key to proving Sirius's innocence. It could be something that was deliberately hidden by the villains who framed him. Once it is discovered, it provides all the necessary evidence to clear his name, such as a prediction that Sirius would be wrongly accused and the real perpetrator would be revealed in a certain way.

One interesting plot twist could be that Harry actually has a hidden motive for joining Voldemort. Maybe he wants to learn the Dark Lord's secrets from the inside in order to ultimately defeat him. Another could be that his joining causes a rift among the Death Eaters, as some fear Harry's power and influence. Also, it might lead to a new form of magic being discovered as Harry combines his natural talent with the Dark Arts he learns from Voldemort.

Well, one plot device is the idea of the reader having some special ability or knowledge that attracts Snake. This could be something related to the supernatural elements in Black Butler. Also, misunderstandings are quite common. Maybe the reader misinterprets one of Snake's actions because of his quiet nature, which then leads to some drama and relationship development. And there's the classic 'fated encounter' plot, where it seems like the universe has brought the reader and Snake together for a specific purpose within the Black Butler setting.

Often, a common plot point is the adjustment of the story's timeline. Since Sirius being Harry's father changes a lot, the fanfiction may need to re - work how events like the first meeting between Harry and Sirius occur. Also, the relationship between Harry and the Weasleys might be different. Maybe they are more cautious or more eager to be part of Harry's life depending on how Sirius's status as Harry's father affects things. And then there's the whole matter of Harry's place in the wizarding world, which could be re - defined.

One idea could be a humorous take on Sirius as a baby with his magical abilities already showing in unexpected ways while in diapers. For example, he might accidentally levitate his diaper when he gets excited.
