His battles would become more one - sided in his favor. With dragon slayer magic, he could take on dragons much more easily. Instead of having to use complex spells and strategies to avoid a dragon's attacks, he could directly counter them with dragon slayer magic.
In battles, Harry's newfound dragon slayer magic would revolutionize his approach. When facing dragons, he could use spells that specifically target their weaknesses, which normal wizards may not know. This would not only make the battles shorter but also less dangerous for him. Against other opponents, like dark wizards who might be using dragon - related magic or summoning dragons, Harry would have a distinct advantage. He could disrupt their magic or quickly defeat the summoned dragons, changing the tide of the battle.
His Hogwarts experience would likely be very different. For one, he might be more physically fit and confident in combat situations. He could be less intimidated by the likes of Snape or Malfoy, as the Dragon Slayer would have taught him to stand up for himself. Also, he might introduce some new skills to Defense Against the Dark Arts, like dragon - slaying techniques adapted for magical creatures.
If we consider Harry Potter as a God Slayer in fanfiction, the characters would experience significant changes. Harry himself would have a different aura about him. His confidence would grow exponentially as he realizes the magnitude of his new - found abilities. He would start to question some of the established rules of magic. Hermione would be constantly by his side, trying to analyze and understand the new powers from a theoretical perspective. Ron, on the other hand, would be the one to keep Harry grounded, reminding him of their roots and the importance of friendship. And the villains would be more afraid of Harry, seeing him as a much greater threat than before, which could lead to them forming new alliances or strategies to deal with him.
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.
His relationships would also change. Some friends might distance themselves because they are so immersed in the magical world. Others might stay by his side, and together they'd explore a new kind of adventure, one without magic but full of human emotions and real - world challenges.
His overall posture and movement would change too. With the wings, he would need to be more aware of his surroundings to avoid knocking things over with them. His gait might be different as he adjusts to the new weight and balance on his back. Also, his face might have a more 'otherworldly' look. Maybe his eyes would have a glint like a dragon's, or his skin could take on a slightly scaly texture near the base of the wings.
At first, his friends would be shocked. Hermione might think it's some kind of dark magic at first glance. But as Harry shows them what he can do, she would start to analyze it scientifically. Ron would be more awed. He'd be like a kid seeing a new cool trick. They would both support Harry in exploring this new ability, but also be a bit cautious as they don't fully understand where it comes from or what the implications are in their wizarding world.
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.
His friends would probably be initially shocked. Hermione might be a bit scared at first but then would be very interested in studying his new form. Ron would likely be in awe but also a bit jealous of Harry's new power as a dragon. Overall, their friendship would have a new dynamic as they have to adapt to Harry's different form.
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.
The plot could involve Harry discovering a prophecy that links his destiny to slaying a powerful dragon. So, he embarks on a journey to find and defeat it. Along the way, he might have to learn new spells or combat techniques specific to dragon slaying.
