In this fanfic, Ayra could be on a mission to avenge someone who was killed by the Night King. She disguises herself and infiltrates the Night King's lair. There, she finds a way to disrupt his source of power. While he is weakened, Ayra takes advantage of the situation and engages in a fierce duel with him. Despite his powerful attacks, Ayra's agility and courage enable her to overcome him and deliver the fatal blow.
One possible plotline could be that Ayra has been on a long and arduous journey to reach the Night King. Along the way, she meets various allies who help her in different ways, like providing her with special weapons or knowledge about the Night King's weaknesses. When she finally faces the Night King, she uses her stealth and quick - thinking skills, perhaps getting in a surprise attack and finally slaying him with a well - placed strike.
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.
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.
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.
Maybe in the fanfic, Death is not a traditional Grim Reaper - like figure but rather a form of an evil curse that has been plaguing the ninja world. Naruto, being the hero, is the only one with enough positive energy and determination to face it. He could start by gathering allies who have also been affected by this 'Death' curse. Together, they form a plan. Naruto would be the vanguard, using his speed and strength to break through the defenses of the curse - based Death and then use his willpower to shatter it completely.
One plotline could be that Simba's mate is pregnant. The pride then prepares for the new arrival. They might search for a safer place within the Pride Lands for the cub to be born, while also facing challenges like food shortages or threats from other animals.
One possible plotline could be Sasuke's revenge-driven journey leading up to the moment he kills Danzo. He might discover new secrets about Danzo's past misdeeds that fuel his hatred even more. For example, he could find out about Danzo's role in the Uchiha massacre in greater detail. Another aspect could be the aftermath of the killing. How does it affect the Hidden Leaf Village? Does it lead to chaos or a new understanding of Sasuke's motives among the villagers?
In a fanfic, Arya could have a more elaborate plan. She might gather evidence of Walder's treachery against House Stark first. Then, she uses her network of allies (either those she made during her travels or some remaining Stark loyalists) to isolate Walder. She could stage a public trial of sorts in the courtyard of his own castle, where she publicly accuses him and then executes him, sending a strong message to all those who wronged the Starks.
One possible plotline could be that Jon and Daenerys travel back in time to before the Night King was created. They might try to prevent the events that led to his creation. For example, they could stop the Children of the Forest from using dragonglass to create the first White Walker. This would change the entire future of Westeros and prevent the Great War against the dead.
One possible plotline could be her journey to discover her true powers. As the daughter of Poseidon, she might have the ability to control water in unique ways, like creating massive tidal waves or even communicating with sea creatures. She could face challenges from other mythological beings who are jealous of her powers.
Perhaps Ezra gets transported back in time and encounters a younger Palpatine. Ezra tries to prevent Palpatine from turning to the dark side, but in the process, he has to face the challenges of the political and social environment of that time. This could lead to a complex story of moral dilemmas and power struggles.
