If Harry was taken away from his parents in a fanfic, he might be more distrustful. Without the love and security of his parents in his early years, he could have a harder time forming close relationships. He may also be more self - reliant, having to figure out things on his own from a young age.
Harry could become more of an outcast in a fanfic where he's removed from his parents. Without their guidance and the family name to back him up, he might be shunned by some in the wizarding community. This could make him more bitter and cynical. On the other hand, it could also make him more determined to prove himself. He would have to fight harder for respect and recognition, and this could shape him into a more hardened and perhaps more strategic character. He might also develop a different moral compass, depending on who or what raised him. If he was raised by a group with a more gray - area view of right and wrong, his decisions in difficult situations could be very different from the Harry we know in the original series.
Naruto would likely be more distrustful. Growing up without his parents and under Danzo's influence, he might not have the same sense of hope and determination that he had in the original story. He could be more cynical about the village and its leadership.
He would be more confident. Without the trauma of losing his parents, Harry would not have that underlying sense of insecurity. He would probably be more outgoing and less hesitant in making friends and taking risks.
His character development would take a very different path. Naruto would likely be more introverted in some ways. Since he has his family's love and support, he doesn't need to constantly seek validation from others. He'd be more focused on his family's expectations and traditions. His values would be more in line with those of his parents. For example, he'd have a deeper understanding of loyalty and sacrifice from an early age. He might not be as impulsive either, as his parents would be there to guide him and teach him to think before acting.
Harry would likely be more cynical. Without the love and support of his parents, he'd grow up feeling abandoned. He might be more distrustful of others, especially those who claim to be helping him. For example, he might not trust Dumbledore as easily as in the original story.
He might be more confident. Since his grandfather has more life experience, he could instill in Harry a sense of self - assurance from an early age.
If Harry was raised by his mother, his understanding of magic would be different. His mother could pass on her own unique magical knowledge and skills to him. He might be more proficient in certain areas of magic earlier on. Also, his view of the wizarding world would be more positive as he grows up in a nurturing magical environment, rather than the hostile one at the Dursleys'. This would likely make him a more confident and less brooding character, and his decisions might be more based on hope and love rather than revenge or survival.
His character might be more distrustful. Since his parents left him, he may have a hard time trusting others, especially authority figures like Dumbledore. He could be more independent too, having to fend for himself from a young age. For example, he might not be as quick to accept help from others at Hogwarts.
Naruto would likely become more independent. Without his parents' attention, he would have to fend for himself more. He might grow up quicker and be more self - reliant. For example, he would have to learn to cook and clean for himself at a much younger age.
In some fanfics, a time - traveling accident might cause Harry to be taken away from his parents. For example, if a wizard from the future accidentally creates a rift in time while trying to save Harry from Voldemort in a different way. They end up pulling Harry into the future, separating him from his parents in the past. This could lead to a story where Harry has to find a way to get back to his own time and reunite with his family, all while dealing with the strange future world he's landed in.
He would likely be more confident. Growing up with his grandparents, who presumably love and support him, he wouldn't have the self - doubt that came from living with the Dursleys. He would be more self - assured in his magical abilities from the start.
