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.
One interesting plotline could be McGonagall mentoring a young and troubled student. It would show her nurturing side, which we don't always see in the original books. Another could be her taking on a special mission during the war, like protecting a secret magical artifact. This would highlight her bravery and loyalty to the wizarding world.
Another plotline might involve a time - travel scenario where Harry Potter and Minerva McGonagall have to work together to change an event in the past that is threatening the future of the wizarding world. This could lead to some really cool interactions as they navigate through different eras.
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.
One common plotline is McGonagall protecting Harry from the Ministry of Magic when they wrongly suspect him of something. For instance, if the Ministry believes Harry is using Dark Magic, McGonagall stands up for him, using her influence and knowledge of Harry's character to prove his innocence.
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.
One interesting fanfiction could be about Minerva McGonagall's early days as a teacher and how she interacted with a young Harry Potter. It might show her guiding him in secret before he even knew he was a wizard.
There might be a fanfic that focuses on Minerva McGonagall's backstory in relation to Harry Potter. For example, it could explore her thoughts and feelings when she first saw Harry as a baby, knowing the prophecy.

In some fanfictions, the plotline might involve a time - turner related incident. Maybe Hermione gets into some sort of trouble with time - traveling that only McGonagall can help her with. As a result, McGonagall adopts her to keep a closer eye on her and make sure she doesn't get into more dangerous situations. This could lead to some really interesting scenes where McGonagall teaches Hermione more advanced magic and Hermione uses her knowledge in new and creative ways under McGonagall's guidance.
