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.
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.
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.
Arcturus Black might be portrayed as a wizard with a deep understanding of ancient magic in the fanfiction. He saves Harry Potter perhaps because he sees in Harry the potential to defeat the dark forces that are plaguing the wizarding world. His character could be a blend of mystery, power, and a sense of moral obligation towards Harry.
In the fanfiction, Arcturus Black is likely an important figure in the wizarding world. He might be a powerful and knowledgeable wizard from the Black family. Maybe he has a long - standing reputation for his magical abilities and wisdom, which is why he is chosen to train Harry Potter.
In such a fanfiction, Harry might grow up with a different set of values and skills. Arcturus Black could instill in him a more traditional pure - blood wizarding family's knowledge. He may have different magical training compared to what he got in the original series, perhaps more focused on family - specific magic or ancient spells.
His character could develop in a more sophisticated way. Cassiopeia might expose him to a wider range of magical knowledge and social etiquettes. He would grow up with a better understanding of the complex web of wizarding families and their histories. This would make him a more well - rounded character, better equipped to handle the political and social aspects of the wizarding world. He may also develop a more nuanced view of good and evil, not just seeing things in the simple black - and - white way as he did in the original story.
Harry's character would undergo a significant transformation. The Cullens' values of self - sacrifice and protecting the family would influence him. He'd likely become more empathetic towards non - human beings. His magic might be used in more creative ways to adapt to the Cullens' lifestyle. For instance, he could use magic to make their home more vampire - friendly. His confidence would grow as he learns from the Cullens' strong family bond.
He would likely be more confident. Growing up with gods would give him a sense of self - assurance that he lacks in the original story. He might be less hesitant in using his powers.
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.
His character would be more stable. Without the Dursleys' abuse, he would be less angry and more trusting.
