Well, this type of fanfiction changes the original story in multiple ways. Firstly, the character of Harry is likely to be more reserved and perhaps more studious under Snape's care. Snape, being a strict teacher, would enforce discipline in Harry's study of magic. Secondly, the whole mystery around Harry's parents and his role in the wizarding world might be revealed to him in a different order. Since Snape has his own secrets and grudges related to James Potter, he might tell Harry things in a different light compared to Dumbledore. Moreover, the relationship between Snape and the other Hogwarts faculty would also change. They would have to accept Snape as Harry's guardian, which could lead to some interesting power dynamics and storylines at Hogwarts.
The concept changes the original story a great deal. Firstly, Harry's personality would be different. Instead of the kind - hearted boy we know, he might be more cynical due to IT's influence. Secondly, his relationships would change. His friends might be more wary of him. Also, the way he approaches magic could be altered. He may use magic in more unorthodox and perhaps darker ways.
It changes the story by expanding the scope of Harry's world. Instead of just Hogwarts and the UK wizarding world, he's now part of an international magical community. His values and beliefs are likely to be more diverse.
The whole dynamic of the fight against Voldemort would shift. If Harry were Snape's son, Snape's loyalty and actions throughout the series would be re - evaluated. Harry might have access to different knowledge and skills that Snape could pass on. His connection to the Dark Arts might be more nuanced. Also, the way the other Hogwarts professors treat Harry would be different. They might be more cautious or more expectant of him, given his new family connection.
Harry in this fanfiction is likely to be more ruthless. Voldemort's upbringing would make him less empathetic. He may value power above all else and be more willing to use dark magic to achieve his goals. His relationships would also be different. He wouldn't have the same close - knit group of friends as in the original story. Instead, he might be surrounded by Death Eaters or those who follow Voldemort's ideology.
Well, it changes the character development a great deal. In the original, Harry is raised by the Dursleys which gives him a certain view of the Muggle world. But when raised by animals in fanfiction, he has a more instinctual and nature - based view. For example, if raised by owls, he might have a better understanding of communication through flight and have a different relationship with magic related to animals.
Well, a 'Harry raised by Andromeda' fanfic can completely transform the original story's plot. Andromeda, being a Black, has her own connections and knowledge of the wizarding world. She can introduce Harry to different aspects of magic and magical families that he might not have known otherwise. His growth as a wizard is different. He may not rely as much on his friends for emotional support as he gets it all at home. This can change the dynamics of his friendships at Hogwarts. Also, in the battle against Voldemort, Harry may have different resources and allies due to Andromeda's influence.
In this kind of fanfiction, Harry often becomes more proficient in potions and other areas that Snape is good at. His relationship with Snape also makes him more empathetic towards Snape's past and the Slytherin house in general. He may not be as quick to judge people based on their house. Also, he might develop a more complex view of the wizarding world's politics, as Snape is deeply involved in some of the darker aspects of it.
It can lead to a completely different dynamic. Harry might have a new perspective on Snape and the magical world.
He might become more confident in his pure - blood heritage. Since Dorea Black is from an old pure - blood family, she could instill in Harry a sense of pride and belonging that he didn't have in the original story. This could change his attitude towards other pure - bloods and half - bloods.
His character becomes more confident. Since he was raised by a god, he has a certain level of self - assurance that normal Harry might not have. He may not be as easily intimidated by Voldemort or other threats.
