Harry would likely become more stealthy and skilled in combat. His view of the world might change from just the black - and - white of good and evil in the wizarding world to a more nuanced understanding due to Talia's influence.
His character would develop in many ways. Firstly, he would become more self - reliant as Talia's training methods are likely to be tough. He may also become more secretive as he adapts to the ways of the League of Assassins. His sense of justice might be reshaped as he is exposed to Talia's own brand of justice which could be different from what he learned in the wizarding world. He might even develop a new sense of identity as he is no longer just 'the boy who lived' but also an adopted son of Talia al Ghul.
Harry Potter's character would undergo a significant transformation. He would start to question the values he grew up with in the wizarding world. Talia's teachings would make him more calculating and less impulsive. He would learn to use his magic in more creative and unexpected ways, perhaps combining it with the martial arts and stealth skills he learns from Talia. His relationships with others would also change. He might be more distant from his old friends as he delves deeper into Talia's world, but at the same time, he could form new alliances with characters from Talia's side. This new development in his character would make him a more complex and formidable figure, not just against Voldemort but also in the larger context of the two fictional universes colliding.
Well, in this fanfiction, perhaps Harry Potter's situation at the Dursleys gets so bad that Talia al Ghul, who has her own motives which could include using Harry's magic for her own ends or seeing him as a worthy heir, takes him in. She could introduce him to a world of stealth and combat that he never knew before, while he also tries to figure out how to use his magic in this new context.
Talia al Ghul could be a new kind of threat or ally. As a skilled fighter and a character with a complex moral code, she might be initially seen as a threat by the Ministry of Magic. However, she could also prove to be an ally in the fight against Voldemort if she realizes that his goals are in opposition to her own interests. Her skills in espionage could be used to gather information on the Death Eaters.
His magic might be more focused on self - defense and combat. Instead of learning spells for everyday wizarding life like in Hogwarts, Talia might encourage Harry to develop spells that can be used in a fight immediately. So his spellcasting would be more instinctive and less about following the proper incantations and wand movements precisely.
One idea could be that Talia al Ghul somehow ends up in the wizarding world of Harry Potter. Maybe she is on a mission related to some ancient magic that exists there. She could cross paths with Harry and his friends, and her skills in combat and stealth would make for some interesting interactions. For example, she might help them during a dangerous encounter with Death Eaters, using her unique fighting style that combines martial arts and weaponry.
In the Harry Potter world, his friends would probably be very surprised at first. Hermione might be a bit skeptical, wondering how well Harry really knows Talia and what her motives could be. Ron, on the other hand, would be more open - minded and excited for Harry. The wizarding community as a whole might be a bit divided. Some would see it as an interesting union of different powers, while others might be worried about the influence of someone from Talia's world. In Talia al Ghul's world, her father (if he's still alive in the fanfiction) would likely be very controlling and not happy about it. Her allies might see it as a way to gain an advantage through Harry's magic, while her enemies would try to use their relationship against her.
Well, one possibility is that Harry would be trained in combat and stealth from a very young age, much like Damian Wayne was by Talia. He might grow up with a different view of magic, perhaps more as a tool for survival and power rather than just for study at Hogwarts. Also, his relationship with the wizarding world could be very different. Instead of being excited about Hogwarts, he might see it as a place full of naive wizards who don't understand the real world threats he's been raised to face.
At first, it might be a relationship full of mistrust. Batman is always cautious, especially with Talia as she has ties to the League of Shadows. But as they spend more time together, they start to understand each other better. Their relationship could develop into a deep, passionate love that makes Batman question his own principles at times.
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.
