There probably is. Fanfiction is a vast world where all kinds of ideas are explored. Since Naruto and Jiren are from different anime universes, a fanfiction about Naruto being a fan of Jiren could be really interesting. It might involve Naruto somehow learning about Jiren's power and being in awe of it. Writers could play around with different scenarios like Naruto trying to train like Jiren or even seeking his advice in the fanfiction world.
One possible plot could be that Naruto, through some sort of interdimensional rift, witnesses Jiren's power during the Tournament of Power. He becomes so impressed that he starts to study Jiren's fighting style and tries to incorporate it into his own ninja techniques. This could lead to Naruto facing some resistance from his friends and teachers who don't understand his new fascination, but Naruto persists in his pursuit to become stronger like Jiren.
Well, in fanfiction when Naruto releases his power, it could result in some wild and creative scenarios. He could end up using his power to explore new dimensions or time - travel. His power might also attract the attention of ancient and powerful entities. Imagine Naruto using his power to communicate with the spirits of past Hokages in a more profound way, getting advice and unlocking even greater powers from their wisdom.
If Natsu releases his power in the fanfiction, it could also have some unforeseen consequences. Maybe his friends would be worried about him losing control. It could be a moment of great drama, with his friends trying to calm him down while he's in the midst of this power outburst. And it might also attract some unwanted attention from stronger foes who see his power as a threat.
Yes, there are some. In some fanfictions, they might start as rivals but gradually develop a deep bond that could be interpreted as love. However, these are often very creative interpretations that deviate from the original animé's more straightforward rivalry theme.
One key element is the near - extinction of his race. This event had a profound impact on him and motivated his pursuit of strength. Another is his membership in the Pride Troopers, which shaped his fighting style and his sense of justice. Also, the destruction he witnessed in his youth is an important part of his back story.
Jiren is a powerful warrior from Universe 11 in Dragon Ball Super. His back story is centered around his quest for justice and strength. He comes from a race that was nearly wiped out. This tragic event in his past made him determined to become stronger so that he could protect what was left. He trained rigorously under the Pride Troopers and became one of the strongest beings in the multiverse. His sense of justice is unwavering, and he believes that true strength should be used to uphold order and protect the innocent.
When Naruto releases the Kyuubi in the fanfic, it might change his relationship with his sensei, Kakashi. Kakashi would be on high alert, ready to step in if Naruto loses control. At the same time, he would be guiding Naruto on how to better manage the Kyuubi's power. This could bring them closer as Naruto learns from Kakashi's experience. And Naruto's relationship with the other ninja in the village would also shift. Some would look up to him more as a powerful force to protect them, while others might be jealous of his new - found strength.
