His character would develop a strong sense of self - reliance. Since he has no family to fall back on, he has to depend on himself. He would be constantly on guard and more prone to taking risks because he has nothing to lose. He might also develop a darker side, as the lack of parental love could lead to feelings of anger and resentment that he has to deal with.
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.
Harry would likely become more self - reliant. Without the support of his parents, he'd have to learn to take care of himself. He might grow more cautious and distrustful, especially if he doesn't know the real reason for the disownment.
He'd likely be more inquisitive about different forms of magic. Instead of just relying on the spells taught at Hogwarts, he'd constantly seek out new magus - based knowledge.
Harry would likely become more feared by some in the wizarding world. Since the Basilisk is often seen as a terrifying and dangerous creature, his connection to it might make others view him with suspicion. He would also have to grapple with the darker side of magic that the Basilisk represents, which could make him more brooding and introspective.
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.
She often then becomes determined. She realizes she has to rely on herself. So, she starts to explore her magic more independently. In some fanfictions, she might begin to study in secret or practice spells on her own to become stronger. She also might look for new allies, like other outcasts in the wizarding world. This could include befriending house - elves or half - bloods who have also faced discrimination. As she progresses, she can become a very strong and independent character, using her past pain as motivation to succeed.
His magical abilities might develop in a different way. The Malfoys could introduce him to different types of magic or magical artifacts. Maybe he'd learn more about the Dark Arts in a different context, not for evil purposes but just to understand it better. He could also become more skilled in areas like Occlumency earlier on, since the Malfoys might see it as an important skill to protect their family secrets. His relationship with his Gryffindor traits would be tested. He might still have his bravery, but it could be expressed in different ways, like standing up to the Malfoy family's wrongdoings.
He'd be more confident. With a loving mother around, he wouldn't have the insecurities that came from growing up with the Dursleys.
Harry might be more self - assured. Charlus, being from an older time, could have a more no - nonsense approach to teaching Harry magic. This would make Harry more confident in his abilities. For example, he might not second - guess himself as much as he does in the original story.
He develops a more rebellious streak. In the original, Harry was quite respectful of authority in the wizarding world. But being raised by bikers, he might question rules more often. For example, he might not be as quick to follow Hogwarts' strict regulations.
When Harry is in Slytherin in fanfiction, his view of the wizarding world may change. He may start to see the grey areas more clearly. Instead of seeing things as simply good or bad, he realizes that there are many factors at play. This makes him more complex as a character. He may also have to deal with the Slytherin legacy of the Dark Arts. He has to navigate through the temptations and warnings related to it. He might study some Dark Arts spells not to use them for evil, but to understand how to defend against them, which is a very different path from what he would have taken in Gryffindor.
