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.
In this fanfiction, Harry may develop a more refined magical style. Dorea Black, coming from a long line of powerful wizards, could pass on different magical knowledge and techniques to Harry. This would make his magic more sophisticated compared to the rough - and - tumble way he learned in the original series. He might also have a different view of the Dark Arts, perhaps being more knowledgeable about its roots and how to defend against it in a more nuanced way due to Dorea's teachings.
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.
He becomes more humble. Elves are used to serving and being in a subservient position. Growing up with them, Harry would learn the value of every being, no matter their status. He'd be less likely to show off his magical abilities like he might have in the original story.
Harry would probably be more attuned to dark magic. His upbringing by Satan would expose him to different forms of magic and he would have a different understanding of power. He might be more ruthless in achieving his goals and less concerned about the consequences for others. For example, in the original series, Harry was always worried about the safety of his friends, but in this fanfiction, he might use his friends as pawns if it served his purpose.
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.
One interesting plot could be how Dorea Black's different values and family traditions shape Harry's upbringing. Maybe she instills in him a stronger sense of pure - blood pride in a more positive way compared to the negative connotations in the original series. Another plot might involve how Harry's relationships with other characters, like Ron and Hermione, develop differently under Dorea's influence.
Her character might be more confident earlier on. Since Dorea Black is from a magical family, Fem Harry would likely be exposed to magic and magical culture from a very young age. She wouldn't have the same feelings of being an outcast that the original Harry had at the Dursleys. This could lead to her being more self - assured when she arrives at Hogwarts.
Well, in the original story, Harry grows up in a muggle household with no knowledge of the wizarding world until he's 11. If he's raised by Orion Black, he'd be immersed in magic from the start. His view of the wizarding world would be shaped by the Black family's history and values. He may be more confident in his magic abilities and have a different set of friends. Also, his relationship with Dumbledore might be less father - figure - like as Orion would be his main parental figure.
He'd be more adaptable. Quarians live in a different way than wizards, so Harry would learn to be flexible in new situations.
He might become more in tune with nature. Since the Phoenix is a symbol of rebirth and nature in the wizarding world, Harry could develop a stronger sense of environmental magic. For example, he could be able to communicate with other magical creatures more easily, not just the Phoenix.
In this fanfiction, Harry's development could be centered around his understanding of family. Growing up with a scorpion, he has a very different concept of what a family is. This could lead to him having a complex relationship with the Weasleys or other surrogate families in the wizarding world. He might be hesitant to accept their love and care at first, but gradually come to realize the value of a real family. Also, his magical development could be more instinctive, like how a scorpion reacts instinctively to threats, Harry might use magic in a more impulsive yet effective way when in danger.
