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.
Harry's sense of justice would still be there but might be expressed differently. As Jon Snow, he'd be more likely to take matters into his own hands in a more direct way. For instance, instead of relying on the Ministry of Magic's laws like he did in the wizarding world, he'd be more of a lone wolf in Westeros, making his own decisions on what's right and wrong. He'd also probably be more reserved in showing his emotions, as Jon Snow was not one to wear his heart on his sleeve.
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.
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.
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.
One possible plot could be that as a Lannister, Harry would be thrust into the complex political web of Westeros. He might use his knowledge from his past life to outwit his enemies within the Lannister family, like Cersei or Joffrey if they showed signs of the same kind of tyranny as Voldemort. He could also try to reform the Lannister's reputation which was often marred by their self - serving actions.
Harry's bravery, which was one of his most prominent traits, would be very useful in the often - dangerous world of Westeros. He might be more willing to take risks than the average Targaryen. His kindness too would play a role. He could be the one to show mercy in a world where mercy is sometimes seen as a weakness. He would probably adapt his Hogwarts - learned values to fit the different cultural context of Westeros.
Loki's mischievous nature would definitely make Harry more of a prankster. Instead of just being the Boy Who Lived, he'd be the Boy Who Pranked. He might play tricks on Malfoy and his cronies more often and in more elaborate ways.
His confidence would still be there but might be a bit more subdued as he adjusts to the new world. He's used to being a big shot among demigods, but in Hogwarts, he has to start from scratch.
He might become more outgoing. In the Naruto world, the culture is different from the rather formal and often secluded wizarding world. Harry would be exposed to a more boisterous and open - minded society, so he could become more extroverted and less reserved.
