He becomes more detached from the petty squabbles of the wizarding world. His concerns shift from things like Voldemort and Hogwarts politics to the well - being of the entire universe.
When Harry Potter becomes a cosmic deity in fanfiction, his character experiences a huge transformation. He becomes far more powerful, of course, but also more serene and all - knowing. He may start to view magic not just as a tool for good against evil on Earth, but as a force that needs to be balanced across the cosmos. His relationships with his old friends might change too, as they can't fully understand his new cosmic existence.
As a cosmic deity, Harry Potter's character would likely become more patient. In the wizarding world, he was often in a hurry to solve problems. But now, with the whole universe at his fingertips, he has all the time in the world. He also becomes more benevolent in a way that encompasses all beings in the universe. His sense of justice expands beyond what was just right for the wizarding community to what is right for every living thing in the cosmos.
Physically, of course, there are the obvious changes. But more importantly, her personality might become more nurturing. For example, she could be more empathetic towards others' feelings, which might change how she interacts with Neville or other students who were bullied. Also, she might be more in tune with her emotions and not suppress them as much as male - Harry did.
Well, he might gain the power to control the entire universe. He could reshape galaxies, create new stars, and maybe even manipulate time on a cosmic scale. For example, he could ensure that all magical creatures live in harmony across the cosmos.
He becomes more assertive. Instead of waiting for others to tell him what to do, he takes the initiative. For instance, he would be more likely to confront the Ministry of Magic directly about their wrongdoings.
He becomes more authoritative. Harry, who was once just a student and a hero, now has to make decisions for an entire kingdom. So he has to be more assertive and confident in his actions.
He might become more sneaky and calculating. Since he's a thief now, he would have to be good at hiding his actions and planning his 'heists'. His moral compass might also shift a bit as stealing isn't exactly an ethical behavior in the normal wizarding world.
When Harry Potter becomes part phoenix in fanfiction, his relationship with the magical world around him would shift. He could communicate with other phoenixes in a way normal wizards can't. This would give him access to knowledge and secrets that are hidden from others. Also, his role in the wizarding community would become more special. People would look at him not just as the boy who lived, but as a unique being with the powers of a phoenix. He might be seen as a symbol of hope and renewal, much like the phoenix itself.
Naruto's character would change in several ways. Firstly, he would become more strategic. As a lord, he has to plan for the long - term development of his land, which requires thinking ahead. His impulsiveness would be curbed as he has to deal with the complex web of politics. He would also grow in terms of wisdom. He would learn from his experiences and the advice of his advisors. His charisma would be used in a different way. Instead of just inspiring his ninja comrades, he would need to inspire all his people. His sense of justice would expand from individual cases to the overall fairness of his domain, and he would strive to make his territory a model of a just society.
He becomes more serious. Gone is the Naruto who is always cracking jokes.
His relationship with magic could also transform. Without the support of the wizarding community, he may start to explore magic in his own way. He could discover new spells or magical abilities that are not taught at Hogwarts. This newfound knowledge might be a double - edged sword. On one hand, it could help him survive as an outcast. On the other hand, it could further isolate him as it makes him even more different from the others.
His confidence would likely soar. As a warlock, he'd have more power at his fingertips, and this would probably make him bolder in his actions. He might not be as hesitant as he was in the original story when facing challenges.
