One common theme is the clash of different forms of power. Merlin has his old - world magic and wisdom, while Umbridge has her political power within Hogwarts. Another is the idea of resistance. Merlin would likely oppose Umbridge's unjust rules.
Yes, there are. You can find them on various fanfiction platforms. Some might explore Merlin's magic in the context of Hogwarts where Umbridge is trying to enforce her strict rules. It could be a really interesting clash of two different magical universes' power dynamics.
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.
One interesting plotline could be a battle of wits within the Hogwarts faculty. Snape, with his deep knowledge and sly nature, tries to outmaneuver Umbridge's strict and often cruel regime. For example, he might secretly undermine her rules in ways that only the students and a few other faculty members notice.
However, Umbridge can also be a popular character in these fanfictions in a different way. She is the perfect villain. Her over - the - top cruelty and her self - righteous attitude make her a great antagonist. Writers can really explore her nastiness and how the other characters react to her, especially Snape who has his own way of dealing with her.
One great 'Snape vs McGonagall fanfiction' is 'The Clash of Professors'. It shows their different teaching styles and how they often butt heads in Hogwarts' corridors. The author does a great job of portraying their personalities as we know them from the original books.
In many fanfictions, they are often portrayed as equally powerful in different ways. McGonagall's strength lies in her traditional magical skills and her leadership, while Snape's strength is more in his unique knowledge and his ability to adapt to difficult situations. So it's not always clear - cut who is stronger.
One possible consequence could be that she gets fired from her position. If Harry manages to expose her actions, the wizarding school or the Ministry of Magic might not tolerate such blatant abuse of power and take disciplinary action against her.
