Yes, there are likely several fanfics out there with that premise. The idea of Ayra Stark being the one to take down the Night King was a popular theory among 'Game of Thrones' fans even before the show's final season. Fanfic writers often explore such alternate scenarios, giving more depth and different storylines to characters like Ayra in relation to major events like the defeat of the Night King.
Well, it could be an interesting concept. Naruto has his own set of powerful abilities like the Rasengan and his ninja skills. The Night King from 'Game of Thrones' is a formidable undead foe. If Naruto were to enter the 'Game of Thrones' universe, his speed and combat skills might give him an edge against the Night King. However, it also depends on how the writer would handle the magic systems of both worlds colliding.
I'm not entirely sure if there is a specific 'Harry Potter kills the Night King' fanfiction. However, given the popularity of both 'Harry Potter' and 'Game of Thrones', it's very likely that some fans have been creative enough to write such a story. Fanfiction communities are full of these kinds of crossovers, but you may need to search through various fanfiction platforms to find it.
Arya's character could become more confident and self - assured. After killing the Night King, she might see herself as a true hero and a force to be reckoned with. This new - found confidence could change the way she interacts with others, making her more assertive in her opinions and actions.
A good fanfic would have strong character development for Ayra. It should show her growth from a normal girl to a powerful assassin capable of taking on the Night King. For example, her skills in combat and stealth should be well - described and progress throughout the story.
Well, Harry Potter would likely use his powerful magic. He might use the Avada Kedavra curse to kill the Night King. Then, the magical world of 'Harry Potter' would be intertwined with the world of 'Game of Thrones'. Maybe the wizards would then have to deal with the aftermath in Westeros, like helping to rebuild or dealing with the power vacuum left by the Night King's death.
One possible plot could be that Ayra has a premonition about the Night King's plans. She then sets out on a solo mission to stop him. Along the way, she meets some old friends or makes new allies who help her get to the Night King. When she finally faces him, she uses her unique fighting style, a combination of her Faceless Men training and her Stark roots, to take him down. After that, she has to deal with the power vacuum left by the Night King's death and the political implications within Westeros.
There would be chaos. Joffrey is a king, so his death would create a power vacuum. His mother Cersei would be furious and would likely start a manhunt for Arya. The Lannisters might declare war on Arya's family or allies. The political landscape would be completely disrupted as different factions would try to take advantage of the situation.
The origin of the Night King dates back to when the First Men and the Children of the Forest were in conflict. A man from the First Men was turned into the Night King by the Children of the Forest. This was a strategic move on their part, but it backfired horribly. The Night King then started creating more White Walkers and the undead army. He was no longer under the control of the Children of the Forest. His power grew and he became a terrifying force, bent on bringing an eternal winter and darkness to the world.
