Harry's character would develop with a stronger sense of pure - blood wizarding heritage. He might be more confident in his magical abilities from an earlier age, as Arcturus would likely push him to excel in magic. He could also be more calculating in his decisions, having been taught by Arcturus to think like a traditional pure - blood wizard.
He would likely be more reserved. Growing up with Arcturus Black, he'd be influenced by the Black family's rather aloof and traditional ways.
In this fanfiction, Harry's character would develop in a very distinct way. Orion Black, being from a different background than the Dursleys, would offer a more nurturing and magical - centered upbringing. Harry would grow up with a knowledge of his own family's history and power, which would give him a different kind of strength. He would be more attuned to the traditions and politics of the wizarding world. His sense of justice might still be there, but it would be influenced by Orion's perspective. He could also be more of a loner initially, as he has been raised in a unique family environment that not many can relate to at Hogwarts.
His character could develop in a more sophisticated way. Arcturus may expose Harry to a world of high - society wizarding culture. Harry might become more refined in his speech and manners. Also, he could be more secretive and less trusting of others outside of Arcturus' influence, as he's being raised in a more exclusive environment.
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 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.
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.
