An emancipated Harry would be more self - reliant. He would no longer be the 'chosen one' in the traditional sense, but rather a self - made wizard. He would take charge of his own destiny, which means he would train himself harder in magic, seek out his own mentors, and not be bound by the expectations of others. He could even start to question the very foundation of the wizarding world's power structure and work towards changing it.
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.
His relationships would shift. He might distance himself from some friends who he feels are too reliant on the old ways. And he could form closer bonds with those who support his new - found independence. He would also view Dumbledore in a different light, perhaps being more critical of Dumbledore's past decisions.
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.
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.
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.
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.
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.
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 might gain more independence in his actions. For example, he could make decisions about his own education and training without the interference of the Ministry or Dumbledore. He could choose to explore magic in his own way, perhaps even study some dark arts to understand his enemies better, but not necessarily use them for evil.
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 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 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.
