One challenge could be dealing with the traditional teaching structure at Hogwarts. The school had a set way of doing things, and Harry, with his more hands - on and unorthodox approach, might face resistance from some of the more conservative teachers. For example, they might not approve of his idea of using real - life dangerous situations as teaching examples.
Another challenge could be the lack of resources. Hogwarts' DADA curriculum had been in a bit of a mess for years. Harry might find that there are not enough proper textbooks or equipment for his teaching. He would have to be creative in finding alternatives, like using his own memories and experiences as teaching materials, which could also be a bit of a stretch at times.
The students' varying levels of skill and confidence could be an issue. Some students might be too afraid to participate in the practical parts of the DADA lessons, especially when it came to facing things like Boggarts or practicing defensive spells against each other. Harry would have to find a way to encourage and support these students without making them feel pressured.
Another challenge for Harry as Dada teacher could be dealing with the school's bureaucracy. He might want to introduce new teaching methods or change the curriculum, but he has to go through the proper channels. And there could be resistance from some of the more conservative teachers or the school administration who are used to the old ways of teaching Dada.
In this fanfiction, Sanguini could start by explaining the history of vampires in relation to the wizarding world's dark arts. He could talk about how vampires have been both feared and sometimes used as allies in battles against the dark side. Then, he could move on to practical lessons, like teaching students how to identify a vampire's lair and what precautions to take when approaching one. His lessons might also include how to use vampire fangs in certain potions for defensive purposes, making DADA a much more interesting and dangerous subject.
Well, in some fanfictions, Harry might draw on his own experiences facing dark magic. He could use his adventures with Voldemort as real - life examples to make the lessons more vivid. For instance, when teaching about defensive spells against the Imperius Curse, he could talk about how he resisted it in his encounters.
One possible plot idea could be that Harry Potter, using his own experiences with dark magic and defense against it, teaches the Marauders new spells and strategies. For example, he could introduce them to the Patronus Charm in a more in - depth way than they might have learned on their own. Maybe he also shares his insights on how to deal with various dark creatures, based on his encounters in the Forbidden Forest.
One challenge could be controlling his new powers. Deadpool's powers are quite wild, and Harry, used to more traditional magic, might struggle to master them. Another challenge could be how the wizarding world views him. His new powers and the resulting change in his behavior might make him an outcast among some in the wizarding community.
Another challenge would be handling the different houses. Each house has its own identity and sometimes rivalries can get out of hand. A new headmaster would need to find ways to promote unity among the houses, like through new inter - house competitions or joint projects.
One challenge would be the goblins. They are very protective of Gringotts and would not easily give up control. They have their own laws and traditions regarding ownership. Harry would have to deal with their resistance and find a way to convince them or negotiate with them.
One possible plotline could be that Harry, with his knowledge of the Dark Arts from his own experiences, tries to show Tom the true nature of defensive magic. He might start by teaching basic spells like the Shield Charm. Harry could also share his insights on how to resist the allure of the Dark Arts, which is something Tom struggles with in his later years as Voldemort.
One challenge could be the lack of Muggle - style technology knowledge. Harry is from the wizarding world and might not be familiar with the complex electronics and coding that are typically part of AI development. Another issue could be the magical interference. Magic and technology don't always mix well in the Harry Potter universe, so his spells might disrupt the normal functioning of the AI components.
One challenge could be dealing with magical laws and regulations regarding land ownership. There might be restrictions on who can own certain types of magical land, or special permits required.
