Well, considering the founders' different characteristics, Harry's personality would be reshaped. Gryffindor's boldness would likely make Harry bolder in his actions and decisions. Ravenclaw's wisdom would inspire Harry to think more deeply and analytically. Helga Hufflepuff's nurturing nature could make Harry more gentle and caring. And Salazar Slytherin's cunning, if not in a negative way, could make Harry more strategic. He would no longer be the same Harry we know from the original series. His confidence might grow in different areas, and his sense of self would be influenced by the founders' teachings and examples.
His personality might become more traditional in some ways. Since the founders are from an earlier time, their values could rub off on him. He might be more reserved like some of the older wizards.
His personality would likely become more self - assured. Growing up with the founders, he'd be constantly exposed to great magic and wisdom, which would boost his confidence. He might also be more independent as he'd be trained in a more solitary way by the founders.
His personality would likely be a blend of the values of the founders. He'd be extremely courageous like Gryffindor, having that boldness instilled in him from a young age. At the same time, he might also possess Slytherin's cunning, being able to think on his feet in difficult situations. Ravenclaw's influence would make him more intellectually curious, always seeking knowledge. And Hufflepuff's teachings would ensure he was kind - hearted and loyal. Overall, he'd be a more well - rounded wizard with a complex personality.
His personality would likely become more erratic. The Joker's influence is all about chaos and anarchy. Harry might start to laugh at inappropriate times and find pleasure in causing trouble just like the Joker. He could lose his sense of empathy as he is constantly exposed to the Joker's cruel and inhumane behavior.
If adopted by the Malfoys, Harry's personality would be a complex mix. He would be exposed to the Malfoy's elitist views from a young age. This could make him initially seem cold and distant. However, his innate goodness would still be there. He might struggle to reconcile his true self with the Malfoy persona he's expected to have. For example, he might be polite and proper in public as a Malfoy, but secretly help those who are oppressed by the pure - blood ideology, showing that his original kind - hearted personality is still fighting to surface.
He might become more stoic. Gibbs' influence could make Harry hold his emotions in check more. Instead of being so impulsive sometimes, he'd think before acting.
His personality would likely become more conflicted. He has a good heart, but being around Bellatrix would make him question a lot of things. He might become more withdrawn as he tries to hide his true self from Bellatrix.
His personality might become more confident, even a bit arrogant. Growing up in a rich family, he would be used to getting what he wants. For example, he might not be as humble as he was in the original story.
If adopted by Jiraiya, Naruto would probably be more self - assured. Jiraiya would instill in him a sense of pride in his abilities. He'd also be more of a free spirit. Jiraiya's influence would mean Naruto would be more likely to take risks and explore new things without as much hesitation as in the original story. He might also be a bit more flirty, as Jiraiya has his own charm when it comes to the opposite sex.
Percy's personality could become more adaptable. The Avengers operate in a different world compared to where Percy is from. He'd have to learn new ways of doing things. So, he might become more flexible in his thinking and actions. Also, he could become more serious in some ways, as the Avengers often deal with high - stakes situations.
If Harry was raised by the founders in fanfiction, his relationship with his enemies would also change. Voldemort might see him as an even greater threat because of the knowledge and power he gained from the founders. And Harry might not have the same relationship with Dumbledore. He would be more independent and rely more on the teachings of the founders rather than Dumbledore's guidance.
