The White Walkers were a race of ice creatures in the world of 'Game of Thrones'. They were created by the Children of the Forest as a weapon against the First Men. They had blue eyes and could raise the dead. They were extremely powerful and cold, bringing a long winter wherever they went. Their leader was the Night King. They were a major threat to all living things south of the Wall.
The White Walkers were created by the Children of the Forest. Long ago, the First Men were encroaching on the lands of the Children. In an attempt to defend themselves, the Children of the Forest created the White Walkers using dark magic. They were made from captured humans and given powers over ice and cold. However, the White Walkers soon got out of control and became a great threat not only to the First Men but also to the Children of the Forest themselves.
One possible fanfiction could be about a group of survivors who are captured by the White Walkers. They might be used as some sort of bait to draw out other humans. For example, the White Walkers could leave a trail of the captured ones, leading the Night's Watch or other northern forces into a trap.
Well, the White Walkers story in Game of Thrones had so much potential. However, it did seem like the show threw it away. They had been a looming danger for seasons, and fans were expecting a more epic and drawn - out battle and resolution. Instead, it ended quite quickly. There were also some plot holes in how they were defeated, like Arya's sudden ability to take out the Night King. It made the whole build - up of the White Walkers' threat feel a bit wasted.
In this fanfiction's plot, Naruto might team up with some of the local characters in the White Walker world. He could teach them some of his ninja skills in exchange for knowledge about the White Walkers. As the story progresses, Naruto discovers that there is a 'leader' among the White Walkers. He decides that to truly end the threat, he must take on this leader. He trains hard, combining his existing skills with new strategies he's learned from his new allies.
Well, in this fanfiction, Naruto might use his shadow clone jutsu to overwhelm the White Walkers. He could create a horde of clones and swarm them. Also, his Rasengan could be a powerful weapon against the undead. Just imagine Naruto spinning his Rasengan and blasting through a group of White Walkers.
