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.
There are indeed fanfics like that. It's a very creative idea. Imagine the implications for Hermione's character. She would inherit different traits from both Snape and Minerva. Snape's intelligence and his complex nature, along with Minerva's wisdom and strictness. This would change her backstory and how she interacts with other characters in the fanfic world.
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.
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.
One great Snape vs Voldemort fanfiction is 'The Dark Mark's Secret'. It delves into Snape's complex relationship with Voldemort. Snape is constantly in a precarious position, having to play the double agent. The story shows how he uses his wits against Voldemort's brute power. Another one is 'Snape's Hidden Alliances'. It focuses on how Snape manages to outmaneuver Voldemort in some crucial situations. The characterizations are really well - done in both of these, making them engaging reads.
Well, first of all, her personality might be a bit different. Maybe she'd be more reserved like Snape in some ways, but also have Minerva's confidence. In terms of the plot, she could have a different role in the fight against Voldemort. Since her parents are Snape and Minerva, she might be more involved in the inner workings of Hogwarts' defenses. And her relationship with the other students, especially Harry and Ron, would likely change. She might be more of a leader from the start, given her powerful parentage.
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.
Another theme is loyalty. They both have deep loyalty to Hogwarts but express it in different ways. Snape's loyalty is complex and often misunderstood, while McGonagall's is more straightforward. Fanfictions explore how these different loyalties can cause friction between them. In a lot of these stories, their loyalty also brings them together in times of crisis. For instance, when Voldemort's forces threaten the school, they have to find a way to cooperate despite their differences. This exploration of loyalty makes the fanfictions really engaging.
In some fanfictions, their rivalry might be explored in the context of the Hogwarts Houses. For example, McGonagall being a proud Gryffindor and Snape a Slytherin. There could be a story where they have to resolve a conflict between the two Houses, and their different approaches to the situation create a lot of tension and drama.
