Harry would likely become more cynical. Crowley's influence would make him question the black - and - white view of good and evil in the wizarding world. He might be more secretive and less trusting of others.
Harry would develop a more diverse set of values. Ahsoka comes from a different cultural and moral background in the Star Wars universe. So, he might start to see magic and power in a different light. He could become more in tune with nature and the Force, which would add new layers to his character. Also, his sense of loyalty would expand beyond his friends at Hogwarts to include those he meets in the Star Wars universe through Ahsoka.
Harry's character would likely become more independent and self - reliant. Alduin may not coddle Harry like some of his Hogwarts mentors did. He'd have to learn to fend for himself in a strange new world. His sense of adventure would be heightened as he explores Alduin's domain. Also, his view of magic would expand greatly, which could make him more confident in his abilities.
His character would probably become more humble. Elves are not as prideful as some wizards, so Harry might adopt that trait.
Harry's character would likely become more worldly. Living with the Delacours, he'd be exposed to different magical cultures. His confidence might grow as he is part of a loving family environment instead of the neglectful Dursleys. He could become more refined in his magic usage, learning from Fleur's elegance in spell - casting. Also, his sense of self - worth would increase, which could make him a more assertive leader in the fight against Voldemort.
His character would likely become more conflicted. Harry was always a symbol of good in the original series, but under Grindelwald's influence, he'd be exposed to different ideas of power and control. He might start to question his own beliefs.
His character could become more ruthless. Growing up with the Volturi, he'd be exposed to their power - hungry ways.
Harry's character would become more mysterious and less predictable. Growing up with Zelretch, he would be exposed to many secrets of the magical universe, which would make him more cautious and calculating. He might also be less impulsive than in the original story, as Zelretch could instill in him a sense of patience and long - term planning.
His character would become more stoic. Growing up with Batman, he'd be influenced by Batman's serious and determined demeanor. He might be less likely to show his emotions openly like he did at Hogwarts.
His character would likely become more confident. With Wonder Woman as his adoptive mother, he'd have a strong role model. He might be less reserved and more assertive in using his powers. For instance, he'd see how Wonder Woman fearlessly faces her enemies, and he'd be inspired to be bolder with his magic.
Harry's character would likely become more open - minded. Since the OC family is different from the Dursleys and even Hogwarts, he'd be exposed to new ideas. For example, if the family is very laid - back about magic use, Harry might become more experimental with his spells.
