Kurama is often depicted as mischievous in fanfiction. His powerful and somewhat arrogant personality leads him to play pranks on Naruto. He might think it's beneath him to be so closely tied to a human, so he uses pranks as a way to assert some sort of control or just to amuse himself.
Kurama's pride also plays a part. Since he is a great and powerful tailed beast, he may see Naruto as a bit of a naive youngster. His pranks could be a way of teaching Naruto, in a rather unorthodox way, about the power he has within him. For instance, by making Naruto's chakra do unexpected things during training, Kurama is forcing Naruto to learn how to better control it. This is like a tough - love kind of prank. In addition, Kurama's loneliness deep down might also contribute. Pranks could be his way of getting Naruto's attention and forming a more unique bond with him, even if it's through these somewhat annoying antics.
In some Naruto fanfiction, Kurama might prank Naruto by making his chakra go haywire at inconvenient times, like during a spar with Sasuke. It could be a harmless prank where Naruto's Rasengan suddenly fizzles out because Kurama messed with the chakra flow just for fun.
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.
Naruto's blood often plays a crucial role in fanfiction. For instance, it can be the source of new and unique powers. His Uzumaki blood, which is already special in the original series, can be further enhanced or mutated in fanfiction. It could give him abilities like instant regeneration or the power to communicate with animals through a blood - bond.
Naruto might become more solitary. With the great power of Kurama, he may feel that he is different from others and that they can't understand what he's going through. This could lead to him spending more time alone, training to master his new power. But eventually, he would realize that he still needs his friends and their support, and he would come back to his more social self.
Naruto's optimistic personality is a big factor. His ability to always see the bright side of things can rub off on Sakura. For example, if Sakura is worried about a mission, Naruto will be all like 'Don't worry, Sakura -chan! We've faced tougher things and we always come out on top!'. His positive outlook makes Sakura believe that things will be okay.
Naruto's self - confidence gets a huge boost. Kurama's teachings are like a seal of approval. If Kurama believes in him enough to teach him, then Naruto must be something special. This new - found confidence shows in his posture, his speech, and how he faces challenges. He no longer doubts himself as much when it comes to difficult tasks, whether it's a tough battle or a diplomatic negotiation within the ninja world.
Well, Kurama might train Naruto by teaching him how to better control and access chakra. Since Kurama has a vast amount of chakra, it could show Naruto unique ways to harness and use it. For example, it could guide Naruto in creating more powerful and complex jutsu by using their combined chakra in a more efficient way.
Jashin can also be a source of power in fanfiction. Some characters might be tempted to use Jashin - related powers, which come with a cost. This power - seeking aspect can drive the plot forward as characters make choices between power and morality.
Entropy can play a role in Naruto fanfiction by adding an element of unpredictability. For instance, it can disrupt the normal order of things in the Hidden Leaf Village. Maybe the social hierarchy starts to break down due to entropy, and Naruto has to deal with the resulting chaos.
In fanfiction, the Naruto necklace can be a plot device. It might be the key to a mystery. For instance, it could lead Naruto to a secret location.
