Harry becomes more confident. With Albus and Minerva as his guardians, he no longer has to worry about being alone or unwanted. This newfound security allows him to be more assertive in his actions and decisions. For example, he might speak up more in class or during meetings with other students.
His magical abilities improve significantly. Albus, being one of the most powerful wizards, and Minerva, a highly skilled witch, are able to guide him in his studies. They give him advanced training and knowledge that he wouldn't have access to otherwise. This leads to him being able to perform more complex spells and having a better understanding of magic theory, which in turn boosts his confidence even more.
He also develops a deeper sense of belonging. Growing up with them, he starts to understand the true meaning of family. He becomes more empathetic towards others, as he has received so much love. He might be more likely to reach out to a lonely student or help someone in need, just as Albus and Minerva have helped him.
Hermione would likely develop more confidence in her magical abilities. With Albus and Minerva as her guardians, she would have access to a wealth of knowledge and guidance. This could make her less hesitant in using magic in new and untested ways. For example, she might be more willing to experiment with spells she reads about in old books, knowing she has the support of two of the most powerful wizards at Hogwarts.
One heartwarming scene could be when Albus and Minerva take Harry to buy his first set of new robes. They let him choose the ones he likes the most, and Harry's eyes light up with excitement. It shows that he finally has adults in his life who care about his simple joys.
She becomes more nurturing. Usually, she's known for her strictness at Hogwarts, but when she adopts Harry, she softens up. For instance, she might show more patience when Harry makes mistakes in his magic studies.
Harry's character often becomes more shrewd and politically aware. In Slytherin, he has to be. He learns to use his wits in different ways than in Gryffindor. For instance, he might become better at reading people's motives and using that to his advantage.
His relationship with Draco could force him to be more empathetic. Instead of just seeing Draco as an enemy, he has to live with him daily. This could lead to Harry developing a more nuanced understanding of people, and his character could become more forgiving and less impulsive in his judgments.
In these fanfictions, Harry's development can be quite complex. At first, he might rely solely on his magic, but as he faces challenges in Westeros, he starts to develop his non - magical skills too. He could learn the art of swordsmanship from the likes of Brienne of Tarth. His moral compass might also be tested as he has to make difficult decisions in a world where there are no clear - cut good or bad sides. He may find himself having to choose between saving the common people or siding with a powerful house for his own survival.
His magical abilities could develop in new directions. Since different families have different focuses in magic, the Greengrass family might encourage Harry to explore areas he hadn't before. For instance, if the Greengrass family is known for their potions skills, Harry could become an even better potions - maker. His self - confidence may also grow as he is part of a new family structure that supports and encourages him in different ways compared to the Dursleys.
Harry becomes more confident. With Dumbledore as his adoptive father, he has a stronger support system. He is no longer as alone as he was, and this newfound security allows him to take more risks in his magical studies and in fighting dark forces. His sense of identity also shifts. He starts to see himself as part of Dumbledore's legacy, which gives him a greater sense of purpose.
In this fanfiction, Harry's character could develop a fierce sense of independence. Since snakes are often seen as self - reliant creatures, Harry may take on some of these traits. He may be more likely to rely on his own instincts and the skills he learned from the snakes rather than depending on others. Also, his moral compass could be influenced. Snakes in the wizarding world are often associated with cunning, and Harry might use this to his advantage in a more morally ambiguous way at times, but also learn to balance it with the values he inherits from the wizarding community.
At first, Harry might be confused and a bit out of place. He's used to the Gryffindor way of thinking. But in Slytherin, he has to adapt. He becomes more cunning in a positive sense. He learns to think on his feet and use his wits in different ways than he did in Gryffindor. For example, instead of charging into a situation like he might have in Gryffindor, he starts to plan more carefully.
