Harry might be more in touch with his emotions. Andromeda could encourage him to express his feelings, which would lead to a more well - rounded character. He'd also be more open - minded. Living with Andromeda, he'd be exposed to different views on magic and the wizarding world, making him less judgmental.
He'd probably be more confident. Growing up with Andromeda, he'd receive proper care and love, unlike with the Dursleys. This would make him more self - assured in his abilities.
His magical skills could develop in a unique way. Andromeda could teach him things not typically taught at Hogwarts. He might become more proficient in certain areas of magic earlier. Also, his sense of family would be stronger. He'd have a real family unit with Andromeda and might be more protective and caring towards those he considers family, just like Andromeda herself.
Her character might develop in terms of her political influence. Fanfictions could show her using her status as a member of the Black family, albeit a disowned one, to change the wizarding world's view on blood purity. She could be actively involved in promoting equality and her character would grow stronger in her beliefs.
Well, one possibility could be that Harry grows up in a more nurturing environment. Andromeda, having lost her own family, could pour all her love into raising Harry. He might learn different magic from what he would at the Dursleys. For example, he could be exposed to more practical and unique spells that the Tonks family is known for.
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.
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.
Well, it's a really creative take in fanfiction. One could imagine that Harry would have a connection to the Tonks family from the start. Andromeda might pass on different magical knowledge or skills to Harry compared to Lily. It could also lead to a different set of friends and allies for Harry, and perhaps a different view on the wizarding world's social hierarchy.
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.
