Harry's character might develop a split personality. On one hand, there's his normal self, trying to hold on to his values. On the other hand, there's the Venom - influenced side that is driven by power and vengeance. As the story progresses, he would be constantly at war within himself, which could lead to some really interesting character growth. For example, he might either fully embrace the dark side or find a way to completely reject the symbiote's influence and emerge as a stronger and more self - aware person.
His character could develop in a darker direction. The Venom symbiote often brings out the worst in its hosts. So Harry might become more aggressive and self - centered. He could start to view his friends as obstacles and become more isolated.
Yes, Harry Osborn does become Venom in some comic storylines.
In some fanfictions, their relationship develops as they both deal with the loss of Peter Parker. They find comfort in each other and gradually realize they have deeper feelings. Harry might start to see Mary Jane not just as Peter's girlfriend but as someone he truly cares for on his own. Mary Jane, in turn, sees a different side of Harry as he matures and tries to move on from his past issues.
He'd likely be more humble. Elves are not boastful, and growing up with them would instill that in Harry. He might be less likely to seek fame or glory like in the original story.
His character would likely become more well - rounded. Since the Grangers are intellectuals, Harry might become more studious. He'd be exposed to different ways of thinking. For instance, instead of just relying on magic for solutions, he'd learn to use logic and knowledge like the Grangers do.
Harry's character would likely be a mix of confusion and determination. He'd be confused by Voldemort's teachings which go against his natural inclination towards good. But his determination to find his true self would remain. He might develop a sort of duality, acting one way around Voldemort and his followers, but secretly being someone else.
Harry would likely become more in tune with magic on a deeper level. Since Fawkes is a magical being full of ancient magic, Harry might gain new insights into spells and wizardry.
Harry might develop a more confident and assertive personality. Growing up with Dorea, he would be exposed to the power and influence of the Black family. This could make him more self - assured and not as hesitant as he was in the original story. He may also be more politically aware, knowing how the different wizarding families interact and jockey for power. For instance, he would understand the implications of being associated with certain families and how to use those connections to his advantage while still maintaining his moral compass.
Harry's character would likely become more aware of different cultures. Growing up among the Cullens, he'd be exposed to vampire culture. This would make him more open - minded. He might also become more cautious, as vampires have different threats compared to the wizarding world.
He could develop new interests and skills. Since he's in a different family environment, he might be exposed to different hobbies or magical studies. For instance, if Dean's family has a tradition of potion - making in a unique way, Harry could pick up on that and become quite proficient, which would also boost his confidence.
Harry would probably be more wild and less bound by wizarding society's norms. Dragons don't follow human rules, and being raised by them would make Harry question and break free from some of the traditional wizarding ways. He might be more instinctive in his actions and decisions, just like how dragons act on their instincts.
