In this fanfiction scenario, Harry would likely become more cunning in a positive way. He would have to use the Slytherin traits to his advantage while still maintaining his Gryffindor values. The Slytherin students would experience character growth as well. They might start to question their long - held beliefs about blood purity and house superiority. With Harry as their leader, they could become more collaborative with students from other houses, which would broaden their perspectives and make them more well - rounded individuals.
Harry Potter as the Slytherin leader would lead to some significant character developments. He would have to be more diplomatic, as Slytherin has its own internal power struggles. This would make him a more well - adjusted leader. For the Slytherin students, they would see a different kind of leadership. Harry's selfless nature could inspire them to be less self - centered. Some might even start to show acts of heroism, breaking the stereotype of Slytherin being all about self - preservation. Overall, it would create a more complex and interesting character dynamic within the Slytherin house and across Hogwarts.
One possible plot development could be that Harry has to face a lot more internal conflict. He would be associated with a house that his friends might view with suspicion. Also, he might discover new magical abilities or powers that are related to the Slytherin heritage.
For Harry, he might become more open - minded and adaptable. Growing up in the wizarding world, marrying Hana would expose him to a whole new set of values and cultures. He could develop a greater sense of patience and understanding. For Hana, she might become more confident and adventurous. Being with Harry and getting involved in the wizarding world would likely push her out of her comfort zone. She could learn to be more assertive in the face of the magical and often dangerous situations in Harry's world.
For Harry, he could become more in - depth in his understanding of Hogwarts' history and magic. Interacting with Helena Ravenclaw might make him more reflective and less impulsive. As for Helena, through her connection with Harry, she could gain a new perspective on the modern wizarding world and the changes that have occurred since her time.
Harry could also grow in his understanding of the wizarding education system. He realizes that there are many flaws in it. This understanding might lead him to want to make changes in the future, perhaps by influencing how magic is taught at Hogwarts or even in the wider wizarding world. He could start advocating for more inclusive and practical classes after seeing the limitations during his auditing experience.
One possible character development is that Hermione becomes more secretive. As the heir of Slytherin, she might have to hide this fact from others, which would make her more guarded. Another development could be that she becomes more ambitious in a different way. Instead of just aiming for academic success as a Gryffindor, she might start to pursue power or influence within Hogwarts in a more Slytherin - like manner. She could also develop a more complex relationship with the concept of the dark arts. Since Slytherin has a connection to it, she might have to explore and understand it better, which could lead to a more nuanced view of magic in general.
Naruto would likely develop a more complex view of the ninja world. He'd have to balance his own beliefs with the Akatsuki's reputation. He might become more secretive as he tries to keep his true intentions hidden from those who still see the Akatsuki as enemies. His leadership skills would also grow, as he has to manage a group of very powerful and often unruly individuals.
For Harry, he could become more desperate and resourceful. The experience of being captured by Bellatrix might make him more aware of the true nature of the dark side. He could also develop a deeper understanding of the Death Eaters' motives. As for Bellatrix, she might start to see Harry not just as an enemy but as a worthy opponent. This could lead to a strange sort of respect for him, or it could make her even more determined to break him.
One interesting plot could be Harry struggling to fit in with the Slytherin ideals at first. He might be constantly at odds with some of the more traditional Slytherin values like pure - blood supremacy. But then he could gradually change the house from within, making his Slytherin peers see that not all Gryffindor traits are bad and vice versa.
Draco could also change. Having Harry as his brother might make him more protective or more competitive. He might also start to see the flaws in his family's beliefs. As for other characters, Ron and Hermione might view Harry differently and their friendship could be strained or strengthened in new ways.
For Harry, he could become more confident in his teaching abilities. He has always been a learner, but now he has to be the one imparting knowledge. The Marauders might develop a new respect for the importance of DADA. For instance, Sirius might see it as more than just a subject to goof around in. Remus could gain new insights into teaching methods that he can later use when he becomes a teacher himself at Hogwarts.
