If reborn into Marvel fanfiction, Harry Potter's character would experience significant changes. His sense of self - reliance would be tested as he'd be surrounded by powerful superheroes. He'd have to learn to rely on others more, which could make him less solitary in his decision - making. His view of power would also expand. In Hogwarts, magic was the main form of power, but in Marvel, there are so many different sources of power like super - soldier serum, gamma radiation, and alien technology. This would make him more curious and eager to learn about different forms of power and how to use them effectively. His moral compass might also shift slightly as he'd encounter different ethical dilemmas in the Marvel universe that are not the same as those in the wizarding world.
In this fanfiction scenario, Harry Potter might change in several ways. His perspective on life and death could shift. Knowing that his brother has some sort of'reborn' aspect could make him question the finality of death more. He could also become more empathetic towards those who have lost loved ones. Emotionally, he might be more stable as he has a family connection now. This new bond could also make him more willing to take risks in the name of protecting his brother, which is a different kind of motivation compared to just fighting Voldemort for the sake of the wizarding world. Additionally, he may develop new magical abilities or skills as a result of the influence of his brother's unique situation.
He would likely become more hardened. In the Harry Potter world, he had his friends and Hogwarts as a sort of safe haven. As a Stark, he'd be in a much harsher world. He'd probably be more aggressive in protecting his family and territory.
Harry Potter reborn as a Jedi would have a different upbringing. Instead of growing up with the Dursleys, he'd be in the Jedi Temple. This would change his perspective. He'd be more focused on the balance of the Force rather than the battle between good wizards and bad wizards. His relationships would be different too. He'd form bonds with other Jedi, and his loyalty would be towards the Jedi Order. His character would be less about the magic of spells and more about the power of the Force, but his core values of bravery and standing up for what's right would remain.
His attitude towards authority might change. Captain Marvel often challenges authority when it's unjust. So Harry might be more likely to question the Ministry of Magic's decisions. For example, he might not be as hesitant to oppose Umbridge in Hogwarts.
If Harry is reborn as a girl in fanfiction, her character would likely be more empathetic. Girls are often socialized to be more attuned to the feelings of others. So, she might be more concerned about the well - being of her classmates and friends at Hogwarts. Also, she could be more creative in her approach to magic, perhaps using it in more nurturing or collaborative ways compared to Harry as a boy.
He would become more cautious. Harry has faced so much danger in his life, and as a father, he would do everything to keep his children safe. So, he might be a bit overprotective at times.
Harry Potter's character traits would experience a significant transformation if reborn as a Lannister. His Gryffindor - like bravery would be channeled into different areas. He might be more cautious in showing it as the Lannister family values a certain level of political savvy and image - management. His kindness, which was a big part of his character in the wizarding world, would be tested. He would be surrounded by a family that often used more cut - throat tactics. But he could also bring a new perspective to the Lannisters. Maybe he'd introduce a more egalitarian way of thinking within the family, slowly changing their view on power and status. His ability to make friends, which was so important in his previous life, would now be about making allies within the complex political landscape of Westeros.
He'd be more adaptable. Quarians live in a different way than wizards, so Harry would learn to be flexible in new situations.
The plot could change drastically. If Harry is reborn, his entire backstory and origin would be different. This would mean that the events leading up to his fight against Voldemort would be altered. Maybe in this reborn version, Voldemort never became as powerful as he did in the original story because Harry was reborn with some sort of special protection that weakened Voldemort from the start.
He'd probably be more timid at first. Tsuna is known for being a bit of a wimp in the beginning, and even though Harry has his own insecurities, being in a new world and a new body might make him even more hesitant. But as he gets used to things, his brave side from his past life would start to show more. He'd still have that sense of justice and a willingness to protect his friends, just like he did in the Harry Potter world.
