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.
Yes, it can be great. Fanfiction often allows for exploration of ideas that the original series might not have fully delved into. In 'harry potter dada prodigy fanfiction', we might see a character who is exceptionally talented at DADA in ways that Harry and his friends weren't. This can lead to fresh takes on battles against the dark arts, new magical spells and defenses being created, and different relationships within Hogwarts.
One interesting Harry Potter DADA fanfiction could be 'The New Defense Against the Dark Arts Teacher'. In this, a new character with a mysterious past arrives to teach DADA. Another is 'DADA Beyond Hogwarts' which explores how the study of DADA continues after school for the main characters. And there's also 'Unconventional DADA' where the teaching methods are completely different from what we see in the original books.
A great fanfic idea could be that the DADA teacher is actually an animagus who uses their animal form to secretly spy on the Death Eaters. They could be a cat or a bird, for example. In the fanfic, Harry and his friends might start to suspect something strange about the teacher when they notice the animal always seems to be around when important information is being passed. Eventually, they discover the truth and the teacher becomes an even more important ally in their fight against the dark forces.
Another possibility is a reformed dark wizard. Someone who has seen the error of their ways and now uses their in - depth knowledge of dark magic to teach students how to defend against it. This character would have a very interesting backstory, having once been on the wrong side but now using their experiences to help the next generation of wizards in the DADA class.
Common themes include the exploration of magic in new ways. The prodigy might discover new spells or magical techniques related to defense. Also, friendship and loyalty are often themes, as the prodigy interacts with other characters from the Harry Potter world, like Hermione and Ron. They support each other in their battles against evil. And there's also the theme of overcoming challenges, whether it's academic challenges at Hogwarts or life - threatening situations against dark wizards.
Quirrell is also a popular choice in some fanfictions. Some writers like to explore his character more deeply, perhaps giving him a more complex backstory or a different motivation for his actions than what was shown in the original books.
A really cool fanfiction idea is one where the DADA teacher was once a student at Hogwarts who failed the subject miserably. Now they've come back as a teacher to prove that they've mastered the subject. Along the way, they face challenges like old bullies who are now colleagues and students who doubt their abilities.
There might be a fanfiction where the DADA professor is actually an undercover wizard from a far - off land. He brings in unique teaching methods and magical creatures from his homeland, which both fascinates and challenges the students at Hogwarts.
There are fanfictions where the DADA professor is an old wizard who has fought in many magical wars. He has countless stories to tell and his teaching is filled with real - life examples of facing dark magic. His wisdom and experience make him a very appealing DADA professor in these fanfictions.
