Professor Snape is often very popular in such fanfictions. His complex character in the original series gives a lot of room for creative interpretations in fan works. Writers can explore his relationship with Harry in different ways, like having him be more of a mentor figure in ways that were not fully explored in the books.
One possible plotline could be about Harry having special magical training from one of his teachers in a unique way that's not in the original books. For example, Professor McGonagall might teach him a very advanced form of Transfiguration in a more hands - on and personal setting.
She might be a character from a far - off land in the wizarding world. Since she's Harry's mother in this fanfiction, she must have some special qualities. She could be someone who was friends with Dumbledore in the past and through that connection, her story is intertwined with Harry's. For example, Dumbledore might have known about her powers and how they would affect Harry's future, so he kept an eye on Harry from the start.
Obviously, Harry himself would be one of the main teachers. He could teach Defense Against the Dark Arts. Hermione would also be a great teacher. She could teach Transfiguration as she was excellent at it. Ron might teach something like Care of Magical Creatures. He has a lot of experience with magical creatures from their adventures.
In Harry Potter fanfiction, some might consider Remus Lupin as a very competent teacher. He has a deep knowledge of Defense Against the Dark Arts and is able to connect with the students on a personal level. He understands their fears and is patient in teaching them complex magic.
Obviously, Harry Potter himself would be one of the main teachers. He could teach Defense Against the Dark Arts, given his vast experience in that area. Hermione would be a great fit for teaching Transfiguration or History of Magic, as she has a deep knowledge of both.
A possible fanfiction could be about the interactions between Harry and his potions teachers outside of the classroom. For example, Harry might need extra help with a difficult potion and has to seek out his teacher after hours. This could lead to some interesting conversations and a deeper understanding between them, not just as student - teacher but as individuals with their own stories and struggles.
If we consider a non - adult take on 'lemon' in fanfiction, it could be about a bright, citrus - like charm or potion that has some significance in the story. For instance, a lemon - scented potion that is used to enhance concentration during exams at Hogwarts. This kind of fanfiction can be light - hearted and family - friendly.
Well, it could be a story where Lemon has some special powers that she passes on to Harry secretly. Maybe she was a hidden witch with unique magic that no one knew about, not even James Potter.
One possible plot could be that Lemon discovers a dark secret about the wizarding world that even Harry doesn't know. As they try to uncover the truth, they face opposition from some powerful wizards who want to keep the secret buried. Harry uses his skills and connections, and together with Lemon's fresh perspective and new - found magic, they fight against those who would stop them. Along the journey, their relationship as father and daughter grows stronger as they rely on each other for support and protection.
