Harry would probably be more self - reliant. Snape isn't the type to coddle, so Harry would have to figure things out on his own more often. He'd have a sharper tongue, like Snape, and might be less quick to trust others. However, he'd also have a strong sense of justice instilled in him by Snape, who despite his flaws, was always fighting against the Dark side in his own way.
His personality would be a blend of Snape's cynicism and his own inherent goodness. He might be more introverted, spending more time in study and self - reflection. Harry would also have a deeper understanding of the darker side of magic and the wizarding world, which could make him seem a bit more brooding. He'd still be brave, but his bravery would be more of a quiet determination rather than the brash kind we see in the original books.
Harry's sense of humor might be different. Instead of the quick - witted and sometimes sarcastic humor he had in the original story, he could have a drier, more understated sense of humor. Snape's own rather caustic personality could influence Harry to be more subtle in his jokes and remarks, and perhaps a bit more cynical at times.
His personality would be shaped by Snape's cynicism. Harry would be less trusting of others at first glance. He would have a sharper tongue, like Snape, but also a deeper sense of loyalty. Since Snape is often alone, Harry might be more independent and used to handling things on his own. He would also have a great respect for the art of potions and perhaps a more nuanced view of the Slytherin house.
He'd likely be more fearless. Dragons are fear - inspiring creatures, and growing up with them would make Harry less intimidated by threats. He might be more direct in his actions and less likely to second - guess himself.
He might be more shrewd. Goblins are known for their business acumen and cunning. So, Harry could be more calculating in his decisions, not as impulsive as in the original story.
Harry would likely be more fearless and brash. Kenpachi is a bold and fearless fighter, and his influence would make Harry less hesitant. For example, when facing a bully like Draco, Harry might immediately react with physical force rather than just trading barbs. He would be more upfront and direct in his approach to problems.
His personality would probably be more aloof. Since basilisks are solitary creatures, Harry might not be as sociable as in the original story.
His personality would be significantly different. Since house - elves have a very different culture from wizards, Harry would grow up with different values. He could be more empathetic towards the underprivileged in the wizarding world, like the house - elves themselves. He might also be less concerned with the pure - blood/muggle - born divide, as house - elves don't really care about such things. Additionally, he would have a strong sense of duty towards those he considers family, which in this case would be the house - elf that raised him. This sense of family and loyalty would be a core part of his personality.
Harry would likely be more confident in his pure - blood status, at least on the surface. Since he's raised by the Malfoys' twins, he'd be exposed to the pure - blood elitist culture from a young age. He might be more calculating and less impulsive than in the original story, having learned from the Malfoy family's shrewd ways.
Harry's personality would be quite different. He would probably be more cynical and less trusting. Growing up with Snape, who has a rather jaded view of the world, would influence Harry. He might be more sarcastic too. However, he could also be more disciplined. Snape would surely enforce strict rules at home, which would make Harry more organized in his studies and other aspects of his life. Also, his relationship with authority figures at Hogwarts might be more complex. He would respect McGonagall but might also question her more often, having been raised by Snape who often challenges the status quo.
He'd probably be more in tune with nature. Since mermaids live in harmony with the sea, Harry might have a deep respect for all living things. He could be more calm and collected, like the stillness of the ocean depths.
