I recall a fanfic called 'A New Alliance'. It starts with an alternate universe scenario where Snape and Sirius are childhood friends. The story explores how their friendship would have changed the course of events in the wizarding world. It has some interesting plot twists, especially regarding their relationships with other characters like James Potter.
In fanfiction, Sirius Black and Severus Snape often have complex relationships. Sometimes they are portrayed as rivals, with their past grudges from Hogwarts days still lingering. Their different loyalties, Sirius to James and the Order, and Snape to Dumbledore (while being a former Death Eater), add layers of tension.
In many fanfictions, Severus Snape and Lilly are depicted as still friends. Some fanfictions rewrite the canon events to prevent the rift that occurred in the original story. For example, they might change the way Snape was drawn into the Death Eaters or how Lilly perceived Snape's actions. This allows them to maintain their friendship, often with added plotlines that involve them working together against the dark forces in the wizarding world. It gives readers a sense of what could have been and a chance to explore a different side of their relationship that was full of potential in the beginning.
I really like 'A Different Perspective'. In this fanfic, it's set post - war. Sirius, who survived the Battle of Hogwarts, and Severus, who has been pardoned, find themselves living in the same wizarding community. The story focuses on how they both have to deal with their past traumas and how they start to interact with each other. They start off avoiding each other but are gradually drawn together by their shared experiences and the realization that they are not so different after all.
I really like 'A Different Kind of Rivalry'. It shows a unique take on the relationship between Snape and Sirius. Instead of just focusing on their enmity from the original series, it creates a scenario where they have to work together and gradually start to understand and care for each other. It's a refreshing read.
They are an interesting pairing because they are such opposites. Snape is brooding and often seen as the outcast, while Sirius is more bold and carefree. In fanfiction, it's fascinating to see how these two very different personalities could come together.
A possible plot could be that they are both trapped in a magical dimension. They have to rely on each other to find a way out. During this time, they share their stories and secrets. Snape reveals his true feelings about Lily, and Sirius tells about his family. This mutual sharing helps them see each other in a new light and forms the basis of their friendship.
One common theme is redemption. Given their rocky pasts full of enmity, many fanfictions explore how they can redeem themselves in each other's eyes. For example, Sirius might realize that Severus wasn't all bad, and Severus might come to terms with the fact that Sirius had his own reasons for his actions. Another theme is friendship against all odds. They are two very different characters, but fanfictions often show how they can form a bond despite their differences. This can be really inspiring as it shows that even the most unlikely pairs can find common ground.
The exploration of their shared past is also a big theme. Since they were at Hogwarts together, fanfictions often go back to their school days to show how their relationship could have been different. And there's the theme of the power of love and friendship in unexpected places. Despite their initial hatred, they find a connection that goes beyond what they thought possible. It shows that love and friendship can bloom even in the most unlikely situations.
There are also fanfictions where they are magically bonded in some way. This bond makes them feel each other's emotions and forces them to deal with their relationship on a much deeper level. They have to learn to tolerate and eventually accept each other, which leads to a very different kind of relationship compared to what we saw in the original Harry Potter books.
