On the other hand, if Voldemort travels to the future and sees how much Harry has grown and the resistance against him, he might respect Harry in a strange way. He could see Harry as a worthy adversary, which would change the nature of their enmity. Instead of just hating Harry blindly, he might start to understand him better.
Well, in certain fanfictions, time travel could lead to a strange kind of truce between Harry and Voldemort. Maybe they both realize that their fates are intertwined in a way they didn't expect due to the time - traveling events. They might not become friends, but they could have a more nuanced relationship where they avoid direct conflict for a while as they both try to figure out how to get back to their proper times without causing too much disruption to the timeline.
Their relationship would likely become more complex. Since Harry has only known Lily through memories and stories, actually meeting her in person through time travel would be a shock. Lily would see Harry as a grown man, not the baby she left behind. They might develop a more equal, friend - like relationship as they face the challenges of the time - travel situation together.
The relationship would become extremely complex. Harry would be confused and conflicted. He's been taught all his life that Voldemort is pure evil, but now he's been saved by him. Voldemort, on the other hand, might start to see Harry in a different light, perhaps as a tool or as someone with whom he can form an unusual bond. It would be a relationship full of mistrust on Harry's part and manipulative intentions on Voldemort's.
At first, it would be extremely tense. Voldemort would be highly suspicious of Harry's motives. Harry, on the other hand, would be very cautious as he is approaching his mortal enemy. But as they start to interact more, there might be a grudging respect that develops if they find they have common goals.
The relationship would become extremely complex. Harry would no longer be able to simply see Voldemort as pure evil. He would be in a state of confusion and moral dilemma. Voldemort, on the other hand, might start to view Harry as a more interesting pawn rather than just an enemy to be killed. They could develop a strange sort of respect for each other, at least on a surface level.
In a time travel scenario, their relationship could become a complex love - hate relationship. Bellatrix may find herself attracted to Harry's courage and determination in a different way than she's used to. Harry, while disgusted by Bellatrix's actions in the original timeline, may start to see a different side of her when they are in a different time period. This would be a very strange and morally ambiguous relationship, full of internal and external conflicts.
If they both read fanfiction books, Harry might gain a better understanding of Voldemort's motives through different fictional takes. This could lead to him trying to reason with Voldemort in a different way. Voldemort, seeing how some fanfictions portray his relationship with Harry, could either become more enraged or, in a strange way, start to respect Harry's tenacity. It all depends on how the fanfictions are written and what they emphasize about their relationship.
At first, Dumbledore might see Harry as an even greater threat. But as he delves deeper, he could realize that Harry has the potential to be a powerful force for good, despite his dark lineage. So, Dumbledore would start to mentor Harry in a different way, focusing more on helping him come to terms with his identity and use it for positive change.
In a fanfiction scenario, Harry's actions could cause a complete breakdown in any potential for a positive relationship between them. Snape's loyalty to Dumbledore and his role in protecting Harry from the shadows would be put at risk. Harry would have to face the fact that he may have made a huge mistake. And Snape, who has sacrificed so much already, would be in an even more precarious position, both with Voldemort and in the wizarding world in general. This could lead to a chain of events that completely alters the course of the wizarding war, with far - reaching consequences for both Harry and Snape.
If Arthur travels back in time and sees Merlin as a young boy, he might develop a more protective feeling towards him. He'd understand Merlin's journey better and their relationship would shift from just king - and - servant to something more like an older brother - younger brother dynamic. On the other hand, if Merlin takes Arthur to the future and shows him a world without Camelot, Arthur might feel a sense of loss and rely on Merlin even more for emotional support.
