His character could change in terms of his loyalty. Marrying into the Black family might make him more torn between his Gryffindor values and the more Slytherin - like values of the Blacks. He might have to balance his sense of justice with the family's often self - serving motives, which could lead to a more conflicted and complex Harry.
If Harry marries the Black sisters, he might become more politically astute. The Black family has a long history in the wizarding world politics. He would have to deal with their family traditions and power plays. His character could become more calculating, learning from the Blacks' ways of getting what they want.
Harry could become more guarded and secretive. The Black family has a lot of secrets and a certain reputation. He would need to protect his new family members as well as himself. He might also become more aware of the importance of bloodlines and family heritage, which could either strengthen or challenge his existing beliefs about equality in the wizarding world.
He would be more physically capable. Instead of just relying on magic, he could use his Wakandan - trained combat skills. His confidence might also be different. Growing up in Wakanda could give him a stronger sense of self - worth and a more regal bearing, which would set him apart from the original Harry Potter.
In the context of the fanfiction, the Black sisters could be characters with their own unique personalities. They might be related to the well - known Black family in the Harry Potter universe, known for their pure - blood heritage. Each sister could have different magical abilities and outlooks on life.
He'd become more disciplined. The military environment would force him to follow strict rules, which is different from the somewhat loose rules in Hogwarts. His sense of responsibility would also grow as he'd be responsible for his comrades' lives.
Harry would likely have a different sense of self - worth. Knowing he is the son of a powerful underwater hero like Aquaman, he would carry himself with more pride. He might also be more in tune with his emotions, as the ocean is often associated with depth of feeling. And his magical abilities could be enhanced in ways related to water, like creating more powerful water - based spells. He could also be more of a loner, as his unique heritage might make it hard for others to fully understand him.
Harry would probably be more physically fit and combat - ready. Sasuke would train him in ninja ways, so he'd be better at hand - to - hand combat compared to the regular Harry. His approach to facing enemies would be more direct and less about relying solely on magic. He might also be more independent, as Sasuke is not one to encourage over - dependence on others.
He'd be tougher. Hela's not one to coddle, so Harry would have to grow up fast.
Harry would be less socialized in the typical human way. He might not understand things like friendship the same way. He could be more territorial and protective. His magic might also be affected. He might use it more instinctively, like using a spell to protect his 'territory' which in this case could be the area where his wolf pack lives.
He would probably be more in tune with nature. The Inuzuka's lifestyle would make him more aware of the natural world around him. He might be less bookish than in the original and more hands - on with physical activities like running and training with the clan.
He'd likely be much more morally ambiguous. Harry would probably have less regard for the rules and traditions of the wizarding world.
Harry Potter's character would transform in several ways if he joined the police in fanfiction. Firstly, he would become more aware of the Muggle society and its problems. His view of the world would expand beyond the wizarding realm. He would also learn the importance of teamwork in a different context. In the wizarding world, he had his friends from Hogwarts, but in the police, he'd be working with a diverse group of people with different skills and backgrounds. This would make him more adaptable and open - minded. His sense of right and wrong, which was already strong, would be further refined as he deals with the complex legal and ethical issues in police work.
