The implications are numerous. Firstly, in terms of his relationships, Hermione might be both impressed and a bit worried about the new power he has. Ron, on the other hand, would probably be in awe. In the greater wizarding world, the Ministry of Magic would likely keep a close eye on him. After all, a wizard with dragon slayer magic could potentially be a great asset or a dangerous force if not properly controlled.
Well, it could mean a significant shift in the power balance. Harry already has a lot of skills and knowledge, but dragon slayer magic would put him in a league of his own. He might be able to protect Hogwarts and the wizarding world from dragon - related threats more effectively. Also, it could make other wizards view him with a new level of respect or even fear.
A really exciting fanfiction idea could be that Harry Potter is secretly trained by a powerful, reclusive wizard in the art of dragon slaying. This training is done in a hidden location, away from the prying eyes of Voldemort and his followers. As he becomes more proficient, he uses his skills not only to protect the wizarding world from dragons but also to fight against the dark forces that threaten it. He could even form a special bond with a dragon that he spares during one of his slaying missions, and this dragon could later become an ally in his fight against evil.
One possible fanfiction could be about Harry Potter discovering his hidden ability to slay air dragons. Maybe he stumbles upon an ancient spellbook that reveals the secrets of this power. He then has to train in secret to master it, all while dealing with the regular challenges at Hogwarts like exams and rivalries.
In a Harry Potter air dragon slayer magic fanfiction, the plot might revolve around Harry's discovery that he has an ancestral gift of slaying air dragons. This gift was passed down through generations but was lost in history. As he delves deeper into this newfound ability, he discovers that there are different types of air dragons, some good and some bad. The bad ones are being controlled by a dark force that wants to use them to take over the wizarding world. Harry has to figure out how to distinguish between the good and bad dragons, and use his slaying skills only on the ones that pose a threat. He also has to deal with the fact that some of his classmates are jealous of his new power and try to undermine him, but in the end, he overcomes all obstacles and saves the wizarding world from the dragon - controlled menace.
Well, it means he has a new and powerful skill. It could lead to some really interesting plot twists. Maybe he discovers some long - lost secrets that were only accessible through Parselmagic. And it could also put him in a bit of a moral dilemma. After all, Parselmagic has been seen as something evil. But if he can master it for good, it would show his growth as a wizard. It could also change how the wizarding community perceives Parselmagic in general.
There could be a big shift in the power dynamics. If Harry isn't a Potter, some of the alliances and expectations based on his Potter identity would change.
It could be the main character, say, Alex. He has been through a lot of training and has a special connection with magic that gives him an edge in dragon slaying.
Perhaps he leaves in search of a more peaceful life. The wizarding world, despite its magic, has been filled with turmoil for him. He could be seeking a place where he can simply be Harry, not 'The Boy Who Lived' or the hero who defeated Voldemort. He may also be on a quest to discover more about his family's past in the Muggle world, something that has been somewhat overlooked in his life in the wizarding world.
One reason could be that he's tired of the constant danger and battles. After all he's been through, he might just want a normal, peaceful life away from magic. Maybe he wants to start a family in the Muggle world where his kids can grow up without the threat of dark wizards.
One possible reason could be the trauma he has faced. Harry has endured a great deal of pain, from the loss of his parents to the constant battles and threats in the wizarding world. He might want to escape all that and find peace away from it.
It expands the wizarding world by introducing new magical creatures. Fanfiction often includes creatures that were not in the original books, which can inhabit new areas of the wizarding world. For example, some fanfictions might have underwater magical creatures with their own unique magics. This forces the wizards in the story to interact with different ecosystems. Another way is through new forms of magic education. Instead of just Hogwarts - style teaching, fanfiction can show different schools or methods of teaching magic, like a school that focuses solely on defensive magic and has its own set of spells and techniques.
