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.
If Harry was raised by Talia, he would likely be a master of disguise and infiltration. This would give him an edge in the wizarding world. He could use these skills to uncover secrets about Voldemort or other dark wizards that others couldn't. Maybe he would form his own group of allies outside of the typical Hogwarts houses, allies who are more in tune with his upbringing and his new way of thinking about magic and the world.
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.
Well, in this fanfiction plot, perhaps there is some sort of prophecy that links Harry Potter and Talia al Ghul. This prophecy drives them together. As they get to know each other, they find that they share a common goal of protecting the innocent. Harry's experience with Voldemort has made him a fierce protector, and Talia has her own reasons in her world. Their relationship builds as they work side by side, and love blossoms, leading to their marriage. It could be a story full of action, magic, and a unique kind of love.
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.
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.
A possible fanfiction plot could involve Naruto being sent to the DC universe to learn new forms of combat. He meets Talia al Ghul who offers to train him in her unique fighting style. As they train together, they discover that they have more in common than they thought, like their loyalty to their respective causes and their ability to make tough decisions. Their relationship could develop into a strong friendship or something more as they continue to explore each other's worlds.
A fanfiction could also focus on the clash of their ideologies. Naruto believes in the power of friendship and hard work, while Talia has been brought up in a world of power plays and shadowy organizations. This ideological difference could be the source of great conflict and growth for both characters as they try to understand each other and find a middle ground.
One possible aspect of a Naruto and Talia al Ghul fanfiction could be a crossover of their worlds. Naruto's ninja skills and his strong sense of justice could interact in interesting ways with Talia's complex background in the DC universe. For example, they might team up to fight a common enemy that threatens both their realms. Naruto's ability to form strong bonds with his comrades could also influence Talia, who has often been in a morally grey area in her own storylines.
One plot idea could be exploring how Talia deals with her pregnancy while still being involved in the complex world of the League of Assassins. Maybe she has to hide it from some of her enemies within the organization who might see it as a weakness.
Well, one possible plot could be that Batman decides to marry Talia al Ghul to gain access to the League of Shadows' resources in order to fight a greater evil in Gotham. He might think that by uniting with her, he can reform the League from within and use their power for good.
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.
