He'd probably be more in tune with nature. Native American cultures value nature deeply, so Harry would likely have a calm and respectful attitude towards it. He might be more reserved than the original Harry, as Native American cultures often emphasize listening and observing before acting.
Harry would likely be more community - oriented. In Native American tribes, the community is very important. So, instead of being a bit of a lone hero like in the original series, he would be more likely to rely on and work with others. His sense of justice might also be more holistic, taking into account the well - being of all living things, not just humans. He would have grown up with stories and teachings that emphasize the interconnectedness of all life, which would shape his view of good and evil. He might also be more spiritual, having been raised with Native American spiritual beliefs, which could give him a different source of strength in difficult situations compared to his Gryffindor courage in the original story.
One possible plot could be that Harry is found by a Native American tribe after his parents' death. They might teach him their unique magic, which could be different from the European magic in the original series. For example, it could be more nature - based, like using the power of the land, animals and spirits. Harry would grow up with their values and traditions, and perhaps his fight against Voldemort would have a different approach, incorporating Native American beliefs and strategies.
His personality would probably be more aloof. Since basilisks are solitary creatures, Harry might not be as sociable 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.
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.
If Harry Potter was raised by Luffy, his personality would change significantly. Luffy is always cheerful and optimistic, and this would seep into Harry. Harry would be less haunted by his past and more focused on the present and future. His sense of humor would also be different. Luffy has a very simple and direct sense of humor, and Harry would probably adopt some of that. He would be more likely to laugh at the simple things in life. In addition, Harry would be more impulsive. Luffy often acts on impulse, and Harry would be more likely to do the same, which could lead to both great adventures and some trouble. His loyalty would also be more like Luffy's, fierce and unwavering towards his friends.
He might be more reserved. The Malfoy upbringing would likely make him less impulsive compared to his canon self. He could also be more calculating in his actions.
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.
His personality would be much more bold and fearless. Deadpool's influence would make Harry less afraid of taking risks and more willing to jump into dangerous situations without hesitation. He would also be more adaptable as he would have grown up in a constantly changing and chaotic environment created by Deadpool.
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.
