One of the main themes in 'naruto pranks sasuke fan fiction' is competition. Naruto and Sasuke are constantly competing, and the pranks are part of that. Naruto wants to prove he can outwit Sasuke. Humor is also a big theme. The pranks are often really funny and light - hearted, adding a comical aspect to their relationship. And of course, there's the theme of growth. As the pranks happen, both Naruto and Sasuke might learn something about themselves and each other.
One popular 'naruto pranks sasuke fan fiction' is 'The Great Prank War'. In it, Naruto devises all sorts of hilarious pranks on Sasuke, like turning his hair pink overnight. Another one could be 'Prankster Naruto's Surprises for Sasuke' where Naruto uses his shadow clones to set up multiple pranks at once. There's also 'Naruto's Prank Empire Against Sasuke' which has Naruto creating elaborate prank scenarios that keep Sasuke on his toes all the time.
He might replace Sasuke's kunai with candy - shaped ones. It would be really funny when Sasuke tries to use them in a fight or training. Another prank could be that Naruto hides Sasuke's training gear and replaces it with a bunch of candies.
Well, in the fanfiction, Naruto might like to eat those sweet and colorful candies, like the ones that are round and come in different flavors such as strawberry or lemon. Maybe he likes them because they are easy to carry around and can give him a quick energy boost when he's planning his pranks on Sasuke.
One of the funniest pranks could be that the Kyuubi makes Naruto's clones start singing cheesy pop songs instead of following his commands. Naruto often uses his clones in battles and for various tasks. So when he sends them to attack an enemy, they all start singing and dancing instead. This would not only be a shock to Naruto but also to his opponents. Another great prank would be the Kyuubi making Naruto's body move in the opposite direction of what he wants. So when he tries to jump forward, he jumps backward instead, leading to all sorts of comical situations.
One of the pranks Naruto might do is to mess with the Anbu's communication system. He could use his knowledge of chakra and some basic electronics (if we assume some modern - like elements in the fanfiction) to scramble their signals. This would make it difficult for them to coordinate with each other, and they'd be running around trying to figure out what's wrong while Naruto watches from a hiding place, having a great laugh.
Naruto could enlist the help of his friends like Shikamaru. Shikamaru could come up with a really elaborate plan. For example, they could set up a fake mission where Ibiki thinks he's in charge, but it's all just a setup for a series of pranks. They could have actors pretending to be enemy ninjas who act really silly instead of being threatening. And Naruto could keep popping up in unexpected places during this 'mission' to further annoy Ibiki.
Yes, in some fanfics of 'Rokudaime Hokage', Sasuke could be depicted as a Naruto fan. Fanfic authors often explore different character dynamics, and Sasuke having an admiration for Naruto similar to a fan's view can add an interesting twist to the story.
