The Nagini in the Harry Potter series was a large snake. In the story, it was one of Voldemort's Horcruxes. Nagini was under Voldemort's control and was used to do his bidding, often being a weapon in his attacks. It was also used to spy on others as snakes in the wizarding world can be used for that purpose.
Nagini was originally a human woman named Bertha Jorkins. She was cursed and transformed into a snake by Voldemort. Nagini became one of Voldemort's Horcruxes.
It could start with hostility. Harry sees Nagini as a tool of Voldemort, and Nagini is loyal to Voldemort at first. But then, some unexpected events might force them to interact more. For example, they could be trapped together in a magical place, and they have to rely on each other to get out.
Nagini was once a human woman. She was a Maledictus, a person cursed from birth. Over time, due to the curse, she gradually transformed into a snake. Eventually, she became one of Voldemort's Horcruxes. This transformation was a long and tragic process, as she lost her humanity bit by bit as the curse took hold.
Well, Nagini has a rather tragic back story. As a Maledictus, she was doomed from the start. Her transformation into a snake was a slow and painful process. In the wizarding world, being a Maledictus set her apart. And when Voldemort came into the picture, he exploited her situation. He saw the potential in her as a Horcrux. Nagini, in her snake form, was then used by Voldemort to do his bidding, whether it was spying or attacking his enemies. She was a key part of his evil plans.
Yes, there are some out there. You can try searching on fanfiction - specific websites like Archive of Our Own. Just be aware that the concept is quite unusual as Nagini is a snake and in the original series, not really a typical love interest for Harry.
Well, in certain fanfiction scenarios, Nagini could be magically bound to protect Harry. Maybe a spell was cast that made her loyalty shift from Voldemort to Harry. So she would use her venomous attacks or her stealthy movements to keep Harry safe from Death Eaters or other dark forces. She might also be able to communicate with other snakes in the area and get them to help in protecting Harry.
I'm not a big fan of this pairing in a 'lemon' context as it's rather dark and disturbing. However, in fanfiction, it might explore the complex and twisted relationship between Voldemort and Nagini. Maybe it could show how Nagini is not just a servant but has some deeper, unspoken bond with Voldemort.
In many Harry Potter and Nagini fanfictions, the relationship between them is often explored in unique ways. Some might depict Nagini as having a more complex personality than in the original books. For example, she could be shown as a victim of dark magic rather than just a tool of Voldemort.
Harry Potter is likely to be one of the main characters. He and Neville often interact in the original series, and in the fanfic, their relationship could be further developed. Hermione Granger could also be a main character. Her intelligence and knowledge of magic could play a role in whatever adventures or situations Neville gets into. Ron Weasley might be there too, adding his humor and loyalty to the group.
