In fanfiction where Harry Potter is Voldemort's soulmate, how would their relationship develop over time?

Over time, their relationship would also be shaped by the reactions of their respective families and communities. Caius' vampire coven in Twilight might be suspicious of his connection to a Mikaelson - related soulmate. And the Mikaelson family might have their own reservations. But as they stand up for each other against these external pressures, their bond becomes unbreakable.

In such a fanfiction, Voldemort would view Harry as his possession. He'd order Harry around, thinking he can use Harry's wolf - like abilities for his own dark deeds. However, Harry would not go down without a fight. He'd constantly be trying to undermine Voldemort from within. Their relationship would be a very strange and twisted one. Harry would have to pretend to be loyal while actually hating Voldemort with every fiber of his being. And Voldemort, being so arrogant, might not realize how much of a threat Harry still is even in his wolf form until it's too late.

At first, their relationship would likely be one of intense enmity. Harry has fought against Voldemort, and the female Voldemort would inherit that animosity. But if they are forced to interact, say due to a common threat, they might start to respect each other's power. Harry would be cautious but also curious about her motives.

Initially, Harry's raising of Teddy would be based on his love for Teddy's parents. But as time progresses, he would develop his own unique bond with Teddy. They would go through normal family things like holidays and birthdays together. Teddy would rely on Harry for advice on school, friendships, and magic. Harry would be there for Teddy through all his ups and downs. As Teddy becomes a teenager, there might be some clashes in their personalities, but they would always come back together, and their relationship would be one of the most important in both of their lives.

In this fanfiction, the relationship between Harry and Voldemort would be full of contradictions. Voldemort adopts Harry for his own purposes, but Harry has his own will. In the beginning, Harry may be forced to follow Voldemort's orders out of fear. As time passes, he might start to question Voldemort's actions and ideology. Voldemort, seeing Harry's growing independence, could become more controlling. This could lead to a cycle of rebellion and suppression in their relationship. Harry may also find some common ground with Voldemort in their shared loneliness or desire for power, which would add more layers to their complex relationship.

At first, it would probably be quite rocky. Harry has known Severus as a rather cold and strict figure. But as they spend more time together, Harry might start to see the reasons behind Severus' actions. For instance, Severus' strictness in potions class was actually a way to push Harry to be better at something that could save his life one day.

It could start with a lot of animosity on Harry's part, but as he is trained, he might start to see Voldemort in a different light. Maybe he begins to understand Voldemort's motives, though not necessarily agreeing with them.

At first, they might be cautious around each other. Harry, having known Sirius, would be curious about his daughter but also a bit reserved. As they start to work together on small tasks in Hogwarts, like helping out in Dumbledore's Army - like activities, they'd begin to trust each other more. Eventually, they could become very close friends, sharing secrets and relying on one another in dangerous situations.

The soulmate marks can create a sense of confusion. Harry, being the hero, might be conflicted about having a connection to Voldemort. It could make him question his own identity and purpose. For Voldemort, it might be a source of irritation or an opportunity to manipulate Harry.

At first, it would be extremely tense. Harry would be very suspicious of Voldemort's motives. Voldemort, on the other hand, would likely be impatient with Harry's lack of trust. But as time goes on, they might start to understand each other a bit more. Harry could see that Voldemort is not just pure evil, and Voldemort could come to respect Harry's power.
