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.
Harry might become more of an outcast. Warlocks are often seen as a bit more solitary and different from the average wizard. So, his relationships with his friends like Ron and Hermione could change. He might start to feel that they don't fully understand his new powers and the responsibilities that come with being a warlock. He could become more withdrawn and focus more on his own magical studies and growth.
If Harry becomes an Apostle in fanfiction, his sense of self - identity could be completely shaken. He has always been defined by his wizarding heritage, but now as an Apostle, he has to grapple with a new set of values and powers. This could make him more introspective and perhaps a bit more of an outcast, even from his old friends at Hogwarts. He may also become more decisive, as Apostles often have to make quick and important decisions in the face of danger.
He would become more solemn. Harry was always a bit of a hero, but as a Grim Reaper, he'd have to deal with the finality of death constantly. So, his usual light - hearted moments would be fewer.
He would become much more aggressive. Harry is usually a calm and strategic fighter, but as the Hulk, he would rely more on brute force and his first instinct would be to attack rather than think through a plan.
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.
If Harry Potter becomes a Sith in fanfiction, his story would take a very different turn. For starters, his character arc would be flipped. He'd start from a relatively good - natured boy to a power - hungry and ruthless individual. His interactions with other characters would be full of conflict. His former friends would likely try to stop him, leading to intense showdowns. He'd also be more likely to align himself with the darker forces in the wizarding world, such as Death Eaters, and together they could wreak havoc. Moreover, his learning would no longer be about light magic but about the darkest and most forbidden spells and arts.
If Harry becomes a communist in fanfiction, the power dynamics would shift. He'd no longer be just a hero against Voldemort. Instead, he'd be a champion for a new social order. For example, he might work towards a more equal Hogwarts, where students from all backgrounds are treated exactly the same in terms of resources and opportunities. He would also likely question the Ministry of Magic's hierarchical structure and try to make it more democratic.
He would become more confident in his abilities. The Green Lantern ring gives its wielder a sense of power and purpose. Harry, who has always had self - doubts, would grow into a more self - assured person.
He would become more fearless. Riding a dragon requires a lot of courage. Harry, who was already brave, would be even more so. He would be more confident in taking on difficult challenges, knowing he has a dragon by his side.
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.
If Harry becomes a centaur, his relationships would shift. His friends at Hogwarts might be initially shocked. But he could form new bonds with centaurs. He'd learn their values, like loyalty to the herd and respect for the forest. This would make him more empathetic towards different species and change how he interacts with others.
