Well, it really varies. Some fanfictions might have McGonagall punishing Harry Potter for things like sneaking out at night or using magic in the wrong way, just like in the official stories. But other fanfictions could take a different route and have her be more lenient or the situation might be so convoluted that she doesn't actually punish him at all. It all boils down to what the author wants to convey with their story.
McGonagall is known for her sense of discipline in the Harry Potter universe. In fanfiction, she could potentially punish Harry Potter. For example, if he were involved in some sort of dangerous or rule - breaking adventure that put himself or others at risk. However, not all fanfictions follow this pattern. Some might show a more complex relationship between them where punishment isn't the first response, or they might be in a situation where the normal rules don't apply.
In most proper Harry Potter fanfiction, McGonagall is a strict but fair character. If Harry were to break school rules in a fanfic, she might punish him as she does in the original books. However, it depends on the plot and the writer's interpretation of her character.
McGonagall often serves as a mother - like figure in fanfiction. She might comfort Harry when he's facing difficulties with Voldemort or other challenges at Hogwarts. Her influence is seen in how Harry approaches problems. He learns from her to think calmly and use his wits, rather than just relying on his Gryffindor bravado. This helps him make better decisions and grow into a more well - rounded wizard.
He might give Harry detention. Harry could be made to clean the trophies in the trophy room or help Hagrid with some difficult tasks in the Forbidden Forest under strict supervision.
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.
There's also 'McGonagall's Legacy'. This fanfiction focuses on how McGonagall influenced generations of students. It has some really heart - warming moments as it shows her teaching and mentoring. It gives a new perspective on her character that you might not get from the original books.
She might immediately comfort him. McGonagall is a strict but kind teacher. She could put a hand on his shoulder and say soothing words like 'There, there, Mr. Potter. It will be all right.'
She might react with her usual no - nonsense attitude. McGonagall is known for being strict but fair. So she would first listen carefully to Harry's problem, her eyes fixed on him, and then start to analyze the situation. She may not show much emotion on the surface, but deep down, she's concerned for Harry's well - being.
In lemon fanfiction, if McGonagall punishes Hermione, it could be due to violating school rules in a more extreme way than in the original books. For example, if Hermione gets involved in inappropriate behavior during a time when she should be studying or following Hogwarts' code of conduct.
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.
Sexual fanfiction involving Harry Potter is inappropriate in the first place as it goes against the intended nature of the series. Dumbledore, as a moral figure in the original story, would likely be seen as acting in an ethical way to punish behavior that distorts the essence of the story and its characters. However, this is all within the realm of fanfiction which is not part of the official canon.
She might use her magic skills to shield Harry from physical harm. For example, she could cast protective spells like a strong shield charm when Harry is in danger from dark wizards. Also, she may use her authority in Hogwarts to keep him away from those who wish to harm him, like making sure he is not alone in dangerous areas of the school.
