The main characters are Minerva and Harry. But we can't forget about the antagonists. Voldemort or his Death Eaters could be in the background, threatening the safety of Harry even when he is under Minerva's care. And there may be some other Hogwarts professors who interact with Minerva and Harry, such as Severus Snape, who might have a complex relationship with them in the fanfiction.
One possible plotline could be Minerva helping Harry discover his true magical potential outside of just the Boy - Who - Lived status. Maybe she teaches him advanced magic that Dumbledore didn't have time for. Another could be Minerva protecting Harry from the darker elements in the wizarding world, like the Death Eaters, in a more motherly way. She might also introduce him to different magical cultures that he was previously unaware of.
She becomes more nurturing. Usually, she's known for her strictness at Hogwarts, but when she adopts Harry, she softens up. For instance, she might show more patience when Harry makes mistakes in his magic studies.
In some fanfictions, Minerva adopts Harry after realizing the Dursleys are mistreating him. She then takes on the role of a mother figure, which is a huge change for Harry. This could include her taking him shopping for new robes and school supplies in a more loving and nurturing way than the Dursleys ever did. She might also introduce him to the wizarding world in a more personal and gentle way, making him feel truly welcome.
Minerva in Harry Potter fanfiction is often the same strong, intelligent, and strict character as in the original books. She is a Transfiguration teacher at Hogwarts.
One great 'Harry Potter Minerva McGonagall' fanfiction is 'The Transfiguration of McGonagall'. It delves into her early years as a teacher and how she dealt with the challenges. Another interesting one is 'McGonagall's Secret Mission' which shows her on a covert operation during the wizarding war. There's also 'Minerva's Heart' that focuses on her relationships with other Hogwarts staff members.
The exploration of Minerva's past is also quite common. Writers like to fill in the gaps of her history, such as her early days at Hogwarts or her family background. Also, her friendship with other professors, like Dumbledore, is a theme that frequently appears. These relationships are often developed further in fanfiction to show different aspects of her character. For example, how she might support Dumbledore during tough decisions or how they might have disagreed on certain matters in the past.
In this type of fanfiction, usually Minerva McGonagall discovers Hermione's situation of being abused. She takes Hermione under her wing. Hermione might then start to heal and grow in a more positive environment. Minerva could offer her protection, guidance, and a mother - like figure that Hermione might be lacking. This often leads to Hermione becoming more confident and showing more of her true potential at Hogwarts, away from the abuse.
In other fanfictions, Minerva could be involved in a plot that changes the course of Hogwarts' history. She might be the key figure in dealing with a new, unknown dark magic threat. Her wisdom and experience would be put to the test as she tries to protect the school and its students from this danger.
Minerva is interesting because of her strong and no - nonsense personality. In fanfiction, this can lead to great character interactions. For instance, when she clashes with other Hogwarts staff members over teaching methods or disciplinary actions. Her wisdom and experience also make her a great source of knowledge for other characters to tap into.
