Harry's character development would be very different. Since Trigon is a powerful and evil entity, Harry might develop a sense of superiority. He may not have the same moral compass as in the original. He could be more willing to use force to get what he wants, and his sense of right and wrong might be blurred.
In this fanfiction scenario, Harry's character would take a dark turn. Growing up with Trigon, he'd be exposed to constant power struggles and dark magic. He might become more cynical and distrustful of others. His loyalty might not be towards the good side like in the original. Instead, he could be loyal only to Trigon or to his own self - interest, which he learned from Trigon. He may also lack the compassion that the normal Harry Potter has, as he'd be in an environment that doesn't value such qualities.
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.
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.
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 be more assertive. He'd be used to taking action quickly due to his Warrior upbringing. He might be less hesitant in difficult situations compared to the original Harry.
He would be more independent. Goblins are self - reliant, and Harry would likely pick up this trait. He would not be as reliant on others for help as he is in the original story. His view of power would also change. Instead of seeing power in terms of magic alone, he would understand the power that comes from wealth and influence within the goblin community, which could make him more politically astute.
His character would likely be more hardened. Growing up with the Akatsuki, he'd be exposed to a lot of tough situations and battles early on. This would make him less naive compared to the original Harry. He might be more cynical about the idea of pure good and pure evil, having been around the Akatsuki who operate in a more morally complex world. Also, his sense of loyalty might be different. While he'd still value his friends, it might be in a more guarded way as the Akatsuki don't always trust easily.
Growing up with Zatanna, Harry would develop a stronger sense of showmanship in his magic. He may not be as reserved when it comes to displaying his magical abilities. Also, Zatanna's moral code, which may be different from what he would have learned at Hogwarts, could shape him into a wizard with a more fluid view of what is right and wrong in the magical world. This could lead to some interesting conflicts and decisions as he grows older and faces the challenges in the wizarding world.
He'd probably become more reserved. Growing up with the Cullens, who are often cautious and secretive, he'd pick up on those traits. His Gryffindor courage might be tempered with the Cullens' more calculating approach to life.
In this fanfiction, Harry's character would develop in a very different direction. He would likely be more of an outcast. Growing up with a Nundu, he wouldn't have the normal social interactions a wizard kid has. So, he could be more withdrawn and less communicative. But at the same time, he would be very self - reliant and have a strong survival instinct.
His character would likely be a blend of his original self and the influence of the Madoka world. He would still be brave, but his understanding of good and evil might be more complex due to the different nature of the threats in the Madoka universe. For example, the witches are not like the Death Eaters. He might also become more empathetic towards those who are forced into difficult situations, like the magical girls.
In this fanfiction, Harry's character could develop a different kind of courage. Instead of the typical Gryffindor - style courage, it could be more of a quiet, determined courage. Growing up with the Flamels, he may face different kinds of threats that require a more patient and calculated approach. His moral compass might also be influenced by the Flamels' long - standing values. For instance, they might place a high value on the preservation of certain magical elements, and Harry would internalize this value, which would shape his actions and decisions throughout the story. He could also be more confident in his magical abilities, as the Flamels would have trained him in a more personalized and in - depth way compared to Hogwarts' general education.
