If reborn in Twilight fanfiction, Harry Potter's character would be shaped by the new environment. He'd be in a world full of supernatural beings with different rules. He'd have to learn about vampire and werewolf cultures. This would make him more empathetic and strategic. He might also develop new magical abilities or adapt his existing ones to fit the Twilight world.
His character would probably become more complex. He'd have to adapt to a world without wizards at first. He might start off being cautious, but as he discovers the powers and politics of the Twilight world, he'd grow bolder. He could use his intelligence and magic to his advantage.
If Harry Potter were to become a vampire in a Twilight fanfiction, his character development would be quite a journey. Initially, he'd be in shock and confusion about his new state. As he starts to understand the implications, he'd have to learn to live with the constant thirst for blood. This could make him more empathetic towards creatures that are shunned in the wizarding world, like werewolves. His relationships would also shape his character. For example, if he has a romantic relationship with a vampire or a human, it would force him to reevaluate his values. He might become more protective and secretive, but also more in touch with his primal instincts, which would be a whole new side of his character.
He would become more adaptable. Middle - earth is so different from the wizarding world, so he'd have to learn new ways. His character might become more in tune with nature like the elves in Middle - earth.
He'd develop by learning about the different types of magic and how they compare to his ninja abilities. His experiences in the Naruto world, like dealing with loss and fighting for his village, would shape how he approaches the challenges in the wizarding world. For example, he might be more fearless in the face of dark wizards because he's already faced so many tough foes in his past life.
Her character could develop by learning the ways of the Harry Potter world. She'd start as a bit of an outsider with her different origin but would gradually adapt. For instance, she might initially struggle with using a wand instead of her usual means of magic. But as time passes, she'd become more proficient and start to incorporate her own style of magic into the Hogwarts curriculum, changing the way magic is taught there.
He might be more confident from the start. In his past life, Harry grew up without his parents and had a difficult childhood. But as James' brother, he would grow up in a loving family environment. This could make him more outgoing and less hesitant in social situations.
She could develop her identity through her relationships. For example, making friends at Hogwarts who see her as an individual, not just as Harry Potter's sister. She might join a club or a study group where she can shine on her own merits.
Harry's character would become more centered around self - improvement. Goku is always striving to get stronger. So Harry would constantly be looking for ways to improve his magical and physical skills. He might not be as reliant on his friends for support in difficult situations as he is in the original story, instead trying to handle things on his own more often. This could make him seem a bit more independent and self - sufficient.
His character would likely become more edgy and darker. Growing up with demons, he'd be exposed to a lot of negative and cruel things, which would change his view of the world.
He might be more solitary at first. Since ghosts are not as social as living beings in the traditional sense, Harry could be used to his own company. But as he gets to know the living world more, he would start to open up.
His character would likely be much more aggressive. Trigon's influence would push Harry to be more assertive and less hesitant. He'd probably have a quicker temper too.
