Sure it can be done. Imagine a world where the prophecy was misinterpreted. Instead of being enemies, Harry and Voldemort are forced to work together to face a greater threat. As they spend time together, they realize they have more in common than they thought. Harry's sense of justice and Voldemort's ambition could combine in a unique way. They start to trust each other, and a friendship begins to form, which is completely unexpected but makes for an interesting fanfiction concept.
It's definitely possible. In such a fanfiction, it could start with a time - turner accident. Harry goes back in time and accidentally changes the course of Voldemort's life. They end up growing up together, sharing secrets and adventures. Harry could influence Voldemort to use his power for good, and in turn, Voldemort could teach Harry some advanced magic. This would create a bond of friendship between them.
Yes, it is possible. In some fanfictions, they explore an alternate universe where Harry and Voldemort become friends. This could be due to different circumstances in their upbringing or a change in the events that lead to their first encounter. It allows for a very interesting exploration of the characters' personalities and the wizarding world as a whole.
Perhaps in a world where the prophecy was misinterpreted. The original prophecy that linked Harry and Voldemort could have been misread. In this fanfiction, they discover that they were never truly enemies in the way they thought. Instead, they were meant to work together to bring balance to the wizarding world. Harry, with his compassion, would be more open to this idea, and Voldemort, seeing an opportunity for a different kind of power, would join forces with him.
Well, in a fanfiction, it could be possible if Orochimaru has a change of heart. Maybe Naruto's unwavering belief in redemption reaches Orochimaru. Naruto is known for seeing the good in people, and he might be able to convince Orochimaru to turn away from his dark ways. This new - found friendship could lead to Orochimaru using his vast knowledge for the good of the village, like helping with medical research or sharing his knowledge of forbidden jutsus in a more ethical way.
One possible plotline could be that they start to secretly help each other with their studies. For example, Draco might be struggling with a certain type of magic that Harry is good at, like Patronus Charms. In secret, Harry could give Draco some tips. Another could be that they team up to solve a mystery in Hogwarts that no one else is aware of. They might discover a hidden chamber or a secret spellbook together. They would have to keep their friendship a secret because of the rivalry between Gryffindor and Slytherin. Their friendship could also be tested when their respective houses are in competition, but they still find ways to support each other on the sly.
Well, in a fanfiction, anything can be made possible. Maybe it could be a situation where Voldemort has a change of heart due to some powerful magic that alters his very nature. And Harry, being the forgiving person he is, sees a new side of Voldemort and they develop an unlikely bond that over time turns into love. However, this goes completely against the canon where they are bitter enemies.
Well, one way could be through some dark and misinterpreted magic. Maybe Harry stumbles upon an ancient spell that he thinks will defeat Voldemort once and for all but instead, it backfires and revives him. It could also be due to some sort of interference from a powerful dark object that Harry unknowingly uses in the wrong way.
One reason could be a prophecy misinterpretation. Voldemort might initially think that Harry is key to his success in a different way than he originally thought, and so he saves him to figure out this new angle. For example, if there was a prophecy about a 'chosen one' and Voldemort realizes he needs Harry alive to fulfill some part of it that benefits him.
It could be possible if we consider some sort of time - traveling or alternate reality scenario. Imagine if there was a rift in time and space that brought the two universes together. Percy, with his heroic nature, might be a foil to Voldemort's evil. Their relationship could explore themes of nature vs. nurture, as Percy was raised in a very different environment compared to Voldemort.
One way it could be possible is if Harry were to discover Snape's true loyalties earlier. Maybe if he found out about Snape's love for his mother and all the sacrifices Snape made for the wizarding world while still at Hogwarts. This new understanding could gradually lead to a friendship. For example, Harry could start to see Snape in a different light during a particularly difficult time at school, like when they are facing a common enemy. He might realize that Snape's harsh treatment was more out of a sense of duty and a complex past rather than pure dislike for him.
It could develop after a major event changes Dudley's perspective. Say, Dudley witnesses the true extent of the danger Harry faces in the wizarding world. This could make him feel protective of Harry. He might start to defend Harry against their parents' unfair treatment. And Harry, seeing Dudley's change, would be more open to being friends. They could then start to communicate more, sharing their hopes and fears, and slowly but surely, a friendship would form.
