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.
The encounter with God could introduce a whole new set of characters or entities related to the divine realm. Harry might be tasked with spreading a new message in the wizarding world, something that could either unite or divide the wizarding community. His relationship with Dumbledore might also change as Dumbledore's knowledge and guidance now seem small compared to what God has to offer. This could lead to some interesting conflicts and reconciliations within the story as Harry tries to balance his old relationships with his new - found connection to the divine.
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.
The plot would change a great deal. For one, Harry would be much more powerful physically. So when facing Voldemort, he could use Thor's strength in combat, not just rely on magic. He might be able to take on Death Eaters more easily.
With Ron, it could be a bit more comical. Ron might be a bit jealous of Harry's cool new form at first, but then he would realize how useful Harry's phoenix abilities are. For example, Harry could use his phoenix tears to heal Ron when he gets injured in their adventures. Their friendship would still be strong, but with a new dynamic.
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.
It would change the power dynamics. Magic has been the main form of combat and defense in the Harry Potter world. Guns would introduce a more Muggle - like, instant form of attack. For example, in a duel, instead of casting spells, a wizard could quickly draw a gun. This would make battles more unpredictable and change the strategies used by characters like Harry.
The plot would become very dark. Harry would no longer be the hero, so the fight against Voldemort would likely take a different turn. Maybe Voldemort would see Harry as an ally instead of an enemy. The other characters would have to either try to change Harry back or find a new way to defeat Voldemort without Harry's help.
The plot could change a great deal. For one, the threat of Voldemort might not be as immediate or known in the same way. Harry could be dealing with different dark forces in America, like some ancient and malevolent American - based dark wizards. His journey to discover his past and his power would likely take different turns as he navigates the American wizarding world.
The plot would change significantly. For one, the final battles against the dark forces would be different. Instead of a wand - only battle at Hogwarts, there could be a full - scale war with modern weapons. The Death Eaters might not be prepared for the firepower of things like machine guns or grenades. It could also change the way characters interact. Hermione might study the mechanics of modern weapons instead of just ancient spells, and Ron could be in charge of weapon supplies.
