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.
Well, it would be a whole new world for Harry. He would probably be raised in the goblin society's underground lairs. Growing up, he could be more secretive and shrewd like the goblins. His appearance might even be influenced by their environment, maybe having a more earthy or rugged look. His loyalty would first lie with the goblins, and when he enters the wizarding world, there would be a huge culture clash. He would have to navigate between the two worlds, trying to find his place while also dealing with the prejudices that both sides have towards each other.
Well, one possibility could be that Harry grows up with a very different set of values. Goblins are known for their love of gold and their shrewdness in business. So Harry might be extremely good at handling finances and valuing things in terms of their worth. He could also have a more aggressive and territorial nature, like the goblins. For example, he might be very protective of his 'territory' at Hogwarts, which could be his dorm or the Gryffindor common room.
One possible plot twist could be that the goblins have their own motives for raising Harry. Maybe they see him as a key to some hidden treasure or power. They could be training him in secret goblin magic that no human wizard knows about.
Well, in 'Harry Raised by Goblins Fanfic', a frequent theme is the idea of alternative upbringing. It shows how a different environment can shape Harry's character. Also, power dynamics is a common theme. Since goblins have their own views on magic and power, it often leads to interesting situations when Harry is involved in the wizarding world's power struggles. There's also the theme of loyalty. Harry has to decide who he is loyal to - the goblins who raised him or the wizarding world he is also a part of.
Well, perhaps the story could involve Harry learning the goblin ways of magic and combat. He might grow up with a unique perspective on the wizarding world, seeing things from the goblins' point of view. Maybe he'd have a special bond with goblin characters and use their knowledge to outwit his enemies later in life.
Obviously, Harry Potter himself would be a main character. Then, there would probably be some important goblin characters who raise him. For example, a wise old goblin who acts as his mentor, teaching him everything from magic to the ways of the goblin society.
He would be more independent. Goblins are self - reliant, and Harry would likely pick up this trait. He would not be as reliant on others for help as he is in the original story. His view of power would also change. Instead of seeing power in terms of magic alone, he would understand the power that comes from wealth and influence within the goblin community, which could make him more politically astute.
Harry would be more territorial. Goblins are known to be possessive of their spaces and belongings. So, Harry would probably be very protective of his personal space and things. Also, his sense of justice might be different. Goblins have their own rules and laws, and growing up with them, Harry would view right and wrong from a goblin - centered perspective rather than a wizard - centered one.
Ron might also be a main character. He could be there for moral support to Harry. And his sense of humor might help ease the tension between Harry and the goblins at times. Also, he might accidentally stumble upon a clue that is crucial for helping the goblins, like finding a secret passage in a goblin - related place.
