A common trope is the 'Injury Reminder'. In these fanfictions, Snape's limp serves as a constant reminder of a past battle or dark encounter. It adds a sense of mystery and danger to his character.
One great Severus Snape limping fanfiction is 'The Limping Professor'. It delves deep into how his limp affects his daily life in Hogwarts. It shows how he copes with the pain and the stares of students, adding a new layer to his complex character.
One popular trope is the 'enemies - to - reluctant - allies'. Given their history of animosity, it's interesting to see them pushed into a situation where they have to cooperate. Another is the 'redemption arc' for Snape, and Sirius being a part of that in some way, either by initially opposing it and then coming around, or being a catalyst for Snape's change.
In some fanfiction, Snape might be limping because of an injury he received during a battle, perhaps with Death Eaters or other dark forces. It could also be due to a lingering effect of a spell gone wrong.
The 'unexpected friendship' trope is also common. Despite their long - standing enmity, the Marauders saving Snape can lead to an unexpected bond forming between them. This can range from a grudging respect to a full - fledged friendship. It's always interesting to see how the author develops this relationship. And then there's the 'secret alliance' trope. They might have to keep their new - found cooperation a secret from others in Hogwarts, which adds an element of mystery and intrigue to the story.
In Severus Snape family fanfiction, the theme of identity is really popular. Severus' family can play a big role in shaping his identity. For instance, if his family has a long history of being dark wizards, how does he deal with that? Another theme is family curses or blessings. Some fanfictions explore if there are any magical curses or blessings that have been passed down in the Snape family. And family loyalty is also a significant theme. Whether Severus stays true to his family values or breaks away from them is often a central plot point in these stories.
In these fanfictions, the 'love at first sight' trope can be found. The OC could be immediately smitten by Snape's mysterious aura. Additionally, the 'saving each other' trope is popular. Snape might save the OC from some dark wizard or the OC could save Snape from his own self - destruction. It makes their bond even stronger as they realize how important they are to each other.
One popular theme is redemption. Snape, with his complex past, often has a chance at redemption through his interactions with Ginny. Another is mentorship, where Snape becomes Ginny's mentor in magic or dealing with the darker aspects of the wizarding world. Friendship is also a theme, as they overcome their initial differences to become friends.
Another popular theme is the idea of an alternate universe where they could have been friends. In these fanfictions, events are changed, like Snape not being sorted into Slytherin or James being more understanding, which leads to a different relationship between them.
Another trope is the 'mentor - mentee' dynamic in reverse. Usually, they are both mentors to students, but in some fanfictions, they end up learning from each other. Snape might learn more about emotional openness from McGonagall, while she could learn about some of the darker arts and how to better protect students from Snape. It's an interesting flip of their usual roles.
One common scenario is after a fight with Voldemort or his followers. He might get injured and start limping as a result. Another could be when he's in a hurry to save someone, like Harry Potter perhaps, and in the process he injures his leg.
