She might be more pensive and cautious. Since she's reading about the future, she'd be constantly thinking about how to avoid the bad things she reads and how to make the good things happen. For example, if she reads about a future war, she'll start planning how to prevent it right away.
He would be different in that he'd have access to lantern powers. Instead of relying solely on his wand and magic spells, he'd be using the power of the lantern. His confidence might grow even more as he discovers the vast potential of these new powers.
She would have new abilities that would change her approach to problem - solving. With powers like heat vision and super - speed, she could deal with threats much faster than other wizards. For example, if there was a basilisk on the loose, instead of having to figure out how to use spells to defeat it, she could simply use her super - speed to snatch it up or her heat vision to stun it. This would make her a very different kind of hero compared to the original Harry Potter.
Well, Harry could be more confident in his own power. In the normal series, he had doubts about his abilities at times. But in this scenario, if he's set on destroying Snape, he has to be certain of his magic. He would be more decisive, not hesitating to use his skills against Snape. Also, his relationships with other characters might change. Some might see him as too aggressive in his pursuit of Snape, while others might support him wholeheartedly, creating a divide among his friends.
Harry would likely be more wild in a sense. Dragons live by their instincts, and he'd pick up on that. His magical abilities could be more primal. Instead of relying on the spells taught in Hogwarts, he might use magic in a more raw and unrefined way. Also, his sense of loyalty might be more towards the dragons rather than the wizarding community initially.
Harry would be a different character in this fanfiction. He'd have a different upbringing, being the son of James Bond. This would give him a different perspective on the world. He would be more attuned to the Muggle world's espionage and intrigue, which would affect his relationships at Hogwarts. He might be a bit of an outsider among his peers, as his experiences and knowledge would be more diverse. He could be more of a loner, but also more self - reliant. His decision - making would be influenced by Bond's rational and calculated approach. For example, when facing a dark wizard, he might analyze the situation more like a spy, looking for weaknesses and planning several steps ahead, rather than just reacting impulsively with magic as the original Harry might do in some cases.
He would be more refined. Royal upbringing would instill in him a sense of propriety and elegance that he lacks in the original story.
When it comes to romantic fanfiction, it depends. If it's about his relationship with Ginny, and it's well - written and in line with how he feels, he might be a bit shy but also flattered. But if it's some over - the - top, unrealistic romantic scenario that goes against his true feelings, he could be uncomfortable. For example, if a fanfiction has him falling in love with a Death Eater just for the sake of a 'forbidden love' plot, he would surely object.
Harry would have a different view of leadership. Instead of just being a hero who reacts to threats, he would be more proactive in shaping the wizarding world. Lelouch's influence would make him see the importance of having a vision for the future and using all means necessary to achieve it. He would be more strategic in his approach to fighting against Voldemort and the Death Eaters, perhaps even trying to turn some of them to his side rather than just fighting them head - on.
The story might focus more on her emotions in a different way. A female Harry Potter could be more in touch with her feelings while reading, and this could affect how she reacts to the events in the books. For example, she might cry more easily at sad parts.
As a bride, Harry Potter might have to learn new skills like walking in high - heeled shoes if that's part of the bridal look in the fanfic. He would also have to get used to different social expectations. Instead of being the heroic wizard ready for battle, he could be in a position where he is more of a center of attention in a social sense, which is very different from his usual role. This could make him more nervous or more assertive in demanding respect in this new role.
