One great Lupin and Snape fanfiction is 'The Unlikely Alliance'. It delves into their complex relationship, showing how they might overcome their differences in a post - Voldemort Hogwarts. Another interesting one is 'Shadows of the Past' which explores their student - teacher days and how events back then influenced their later interactions.
I really liked 'Lupin and Black: Unspoken Bonds'. In this fanfic, the relationship between Remus and Sirius is explored in a post - Hogwarts setting. It's a story full of mystery and adventure as they work together to solve a dark magic mystery that's plaguing the wizarding world. Their bond is shown to be unbreakable, even in the face of great danger.
One common theme is redemption. Since both characters have had their share of difficult pasts, many fanfictions explore how they can redeem themselves in each other's eyes. For example, Snape's past actions as a Death Eater and Lupin's lycanthropy - related issues.
Their contrasting personalities also make them an appealing pair. Snape is often seen as brooding and mysterious, while Lupin is more gentle and kind - hearted. Writers enjoy writing stories where these two personalities clash and then find common ground. For example, in many fanfictions, they start off hating each other but then realize they have more in common than they thought, like their loyalty to Dumbledore and their love for Hogwarts.
Another great one is 'Beyond Enmity'. Here, an external threat to the wizarding world forces Snape and Lupin to put aside their differences. The story is full of action and also shows their growth as individuals as they face this common enemy together.
I really like 'Remus and Sirius: Bond Beyond School'. This fanfic focuses on how their bond grew stronger over the years, even with all the difficulties they faced. It has some really well - written scenes that show their loyalty to each other. And then there's 'Sirius Black, Remus Lupin and the Mystery of the Forbidden Forest' which is an exciting read. It involves them going back to Hogwarts to solve a mystery in the forest that has ties to their past.
Well, there's the theme of adventure. They were part of the Marauders after all. Fanfictions often send them on new adventures, whether it's exploring a new part of the wizarding world or solving a mystery. Then there's the theme of sacrifice. They are willing to sacrifice for each other. This can be seen in many stories where one puts himself in danger to save the other. And the theme of love - not necessarily romantic love, but a deep, platonic love that is very strong between them.
One popular 'Sirius Black and Remus Lupin' fanfiction is 'Moonshine and Starlight'. It beautifully explores their relationship with a lot of emotional depth and well - written character interactions.
I'd suggest 'Remus Lupin's Secret and Sirius Black's Redemption'. This fanfic focuses on the secrets that Remus has been keeping and how Sirius helps him come to terms with them. It also delves into Sirius's journey of redemption after his time in Azkaban. It's a heart - wrenching and yet heart - warming story.
A great Sirius Black and Remus Lupin fanfiction often has well - developed characters. It stays true to the original personalities of Sirius and Remus from the Harry Potter series. For example, Sirius's rebellious and loyal nature and Remus's more reserved and intelligent side should be accurately portrayed.
