A common theme is their professional rivalry. They are both powerful wizards and teachers, and in some fanfictions, this rivalry can be quite intense. It might play out in duels of magic, or in competitions for the respect of the students. Additionally, stories may focus on their backstories and how they came to be the people they are. Snape's difficult childhood and McGonagall's early years as a witch could be delved into and how these experiences shape their interactions at Hogwarts.
One popular theme is their friendship. Despite their differences, they are both dedicated teachers at Hogwarts, and fanfictions often explore how they might support each other behind the scenes. Another theme is their possible romantic relationships, not necessarily with each other, but how their views on love and relationships might be. For example, Snape's unrequited love for Lily could be contrasted with McGonagall's more reserved approach to love. Also, their roles during the wizarding wars are often explored in fanfictions. How they coped with the danger, made decisions, and protected the students.
Some fanfictions focus on their mentorship of students. Snape with his Slytherins and McGonagall with her Gryffindors. There could be scenarios where they have to work together to help a student in trouble, like a Slytherin - Gryffindor friendship that they need to support. This shows a different side of their relationship, moving away from their usual house loyalties.
One great Severus Snape and Minerva McGonagall fanfiction is 'The Unlikely Alliance'. In this story, they are forced to work together on a Hogwarts project. Their different teaching styles and personalities create interesting interactions. Snape's brooding nature contrasts with McGonagall's more no - nonsense approach, and as they overcome obstacles in the project, they also start to understand each other better on a personal level.
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 idea could be a story where Minerva and Severus have to team up to protect Hogwarts during a new, unexpected threat. Maybe a dark magic artifact is discovered near the school and they must use their combined knowledge and skills to keep it from falling into the wrong hands.
For Minerva, you could explore her more emotional side. In fanfiction, show her struggling with her feelings for Severus. Maybe she has always seen him as a difficult colleague, but then realizes there is more to him. For Severus, delve deeper into his loyalty. You can write about how his loyalty to Dumbledore and Hogwarts extends to his relationship with Minerva. For example, he would do anything to protect her when Hogwarts is in danger because she is an important part of what he is protecting.
Their different personalities make it interesting. Snape is brooding and often seen as a bit of an outsider, while McGonagall is strict but fair. The contrast between them gives a lot of room for creative writing. For example, how they handle discipline in their respective houses is very different, and fanfictions can explore the clashes or agreements that might occur.
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.
One popular theme is his relationship with Lily. Writers often explore how their friendship developed and how her death affected him deeply. Another theme is his role as a double agent. It's interesting to see how he managed to deceive Voldemort while also trying to protect Hogwarts.
The world of Harry Potter itself is so rich and detailed. Minerva McGonagall is an integral part of that world. Fanfiction about her allows readers to return to the magical world of Hogwarts. Writers can also introduce new magical elements or storylines related to her. For example, they can create stories about her adventures during her youth, or her role in some new magical crisis that was not part of the original books. This gives fans a chance to experience more of the magic and the character they love.
Well, friendship is a big theme. You see, their relationship started as a friendship, and many fanfictions expand on that. They might write about how their different houses in Hogwarts affected their friendship. Also, redemption is a theme. Snape's actions towards the end of the main story can be seen as a form of redemption for his past mistakes, and fanfictions often play with this idea in relation to his relationship with Lily. And of course, the power of love. How Snape's love for Lily influenced his life and actions is always interesting to explore in these fanfictions.
One common theme is her growth as a witch. Fanfictions often show how she hones her magical skills and becomes more confident in her abilities.
