Well, perhaps the Black family's dark magic artifacts play a huge role. Harry could be exposed to them at a young age. He might start to show an aptitude for certain types of dark magic not seen in the regular series. But then he has to struggle with whether to embrace this power or reject it, knowing it goes against what Dumbledore and others would expect.
Harry would probably be more aloof. The Black family has a certain air of aristocracy. So, he might be less approachable than in the original story. He could also be more secretive, having grown up in a family where family secrets are highly guarded.
One possible plot could be that Harry grows up with the Black family's strong sense of pure - blood heritage. He might be trained in different types of magic that the Blacks are known for, like dark arts defenses in a more in - depth way compared to how he was raised by the Dursleys. He could also form closer relationships with Sirius's younger relatives, and perhaps be influenced by the family's more complex family politics.
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.
There is a fanfiction titled 'Black Family Bonds'. This story emphasizes the strong family bonds among the Blacks, despite their differences. It could be about how Regulus Black, in this fanfiction, might have had a different influence on the family than what was initially thought. The fanfictions about the Black family often add new dimensions to the characters and their relationships, making them more complex and interesting to read.
If Harry Potter were raised by the Addams family in fanfiction, his style of dressing would be completely different. Instead of the traditional Hogwarts robes, he might be seen in something more gothic, like the Addams family's style. Also, his sense of humor would be darker. He'd probably find the pranks at Hogwarts a bit too tame compared to what the Addams family gets up to.
It would be really interesting. Harry would grow up in a very different atmosphere. Instead of the strict but loving environment at the Dursleys, he'd be in the spooky and unique Addams family setting. He might learn some very unusual magic from them, and his personality could be a blend of the Addams' eccentricity and his own Gryffindor courage.
Well, in a 'Harry Potter raised by Black Widow' fanfiction, the whole Hogwarts experience might be different. Black Widow would likely be very protective of Harry and might even try to teach him some of her spy - like skills. For example, she could show him how to gather information secretly or how to blend into a crowd unnoticed. And Harry's view on magic might also be influenced by Black Widow's more practical and survival - based mindset.
It would be an extremely interesting scenario. Harry would grow up in a very different cultural and technological environment. The Black Panther's Wakanda is known for its advanced technology and unique social structure. Harry might be trained in Wakandan combat styles instead of traditional wizard dueling. He could also have a different perspective on magic, perhaps integrating Wakandan knowledge with his wizarding abilities.
In a 'Harry Potter raised by Pitch Black' fanfiction, the story would probably deviate a great deal from the original. Harry's values and moral compass might be all over the place. He could be exposed to dark magic from a young age, which would put him in a constant internal struggle. His relationships with the characters we know from the original series, like Ron and Hermione, would be very different. They might initially be enemies or at least very suspicious of him.
