In these fanfictions, Harry's character development can be quite complex. He may start to show a darker side, influenced by the Black family's more ambiguous moral code. However, at the same time, he can also develop a stronger sense of loyalty to his new family. He might become more cunning in his approach to problems, having learned from the Blacks' political maneuvering within the wizarding community. For example, he could use the family's influence to gain access to restricted magical areas or knowledge to further his own growth as a wizard.
Harry's character in this type of fanfiction can develop in a way that he becomes more in tune with his heritage. Since the Black family has a long and storied history, he may start to explore his own roots more deeply. This could lead to him having a better understanding of his parents and their place in the wizarding world. He may also develop new magical abilities or skills that are unique to the Black family, which in turn shapes his personality as he becomes more powerful and self - reliant.
Harry's character might develop a more refined sense of magic. With the Malfoys' influence, he could become more aware of the subtleties of pure - blood magic. His self - confidence could also change. Instead of relying on his Gryffindor bravado, he might learn to be more calculating like the Slytherins. For example, in dealing with school bullies, he might use his wits rather than just charging in.
He could become more shrewd in his dealings. Goblins are known for their business acumen, and living with them, Harry would be exposed to their ways of negotiation and deal - making. This would make him more cautious and calculating in his interactions with others.
Harry's character would likely become more open - minded. Since the OC family is different from the Dursleys and even Hogwarts, he'd be exposed to new ideas. For example, if the family is very laid - back about magic use, Harry might become more experimental with his spells.
He could develop a stronger sense of self - preservation. Since he is in an environment where he is not fully accepted, he has to learn to protect himself, both physically from Dudley's bullying and emotionally from the Dursleys' neglect. So he might become more guarded and less trusting at first.
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.
His character might become more sophisticated. The French culture's influence could make him more refined in his manners.
Harry might become more open and outgoing. The Creevey family's positive attitude could rub off on him, making him less guarded. He could also become more family - oriented, learning the importance of family bonds from the Creeveys.
His character would likely become more edgy and darker. Growing up with demons, he'd be exposed to a lot of negative and cruel things, which would change his view of the world.
Harry would develop a more diverse set of values. Ahsoka comes from a different cultural and moral background in the Star Wars universe. So, he might start to see magic and power in a different light. He could become more in tune with nature and the Force, which would add new layers to his character. Also, his sense of loyalty would expand beyond his friends at Hogwarts to include those he meets in the Star Wars universe through Ahsoka.
Harry's character would likely become more independent and self - reliant. Alduin may not coddle Harry like some of his Hogwarts mentors did. He'd have to learn to fend for himself in a strange new world. His sense of adventure would be heightened as he explores Alduin's domain. Also, his view of magic would expand greatly, which could make him more confident in his abilities.
