Typically, in a 'the walkers twilight fanfiction', we might see the protagonists from 'The Walkers' being thrust into the Twilight world. So, it could be characters like Rick or Michonne. Alongside them, the Twilight characters would also play significant roles. Bella might be involved in some sort of encounter with the Walkers, and Edward could be using his vampire abilities to deal with the new threat or situation that the Walkers bring to the Twilight universe.
One interesting aspect could be the unique interpretations of the characters from 'The Walkers' within the Twilight universe. Maybe it gives a fresh take on their personalities and relationships. For example, how they might interact with the vampires and werewolves in the Twilight world.
There could be. Fanfiction often involves unique crossovers and creative interpretations. Since Naruto has a rich world of its own and the concept of the White Walkers is also quite interesting, it's possible that some fans have been inspired to write a story where Naruto is somehow related to being the 'king of whit walkers'. However, it also depends on how many fans are into both Naruto and the idea of incorporating the White Walker concept into it.
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.
In the comics, the walkers do evolve. They become more dangerous and develop new traits as the story progresses. This adds an extra layer of threat and keeps the plot interesting.
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.
The plot could start with Naruto already being the king of the White Walkers without really understanding how he got there. He then has to deal with the internal politics of the White Walker horde. Meanwhile, he discovers that there are other forces in this new world that are threatened by his new position. So, he has to balance between keeping the White Walkers in line and making peace with these other forces. Along the way, he might also try to find a way back to his own world or bring some of his friends from Naruto's world to help him in this new situation.
