Well, a 'Naruto is Pain' fanfiction might focus on a what - if scenario. What if Naruto was raised by Pain? In this type of fanfiction, Naruto would grow up with a completely different set of values. His view of the ninja world would be shaped by Pain's teachings. He might see the Hidden Villages as corrupt institutions from the start and strive for a different kind of revolution than the one we see in the original series.
One popular 'Naruto is Pain' fanfiction could be 'The Transformation of Naruto into Pain'. It might explore how Naruto, through some unique circumstances, begins to adopt Pain's ideology or power. Another could be 'Naruto: Pain's Legacy' where Naruto has to deal with the after - effects of Pain's actions in a very personal way.
A fanfiction titled 'Naruto's Admiration for Pain' is also worth checking out. It focuses on Naruto's growing admiration for Pain's power and ideology. However, Naruto also tries to change Pain's more extreme views. The story is full of intense dialogues and Naruto's internal struggles.
One great fanfiction could be 'Naruto's Ascent Against Pain'. It really delves into Naruto's mindset during the fight and adds some unique jutsu concepts. Another is 'Beyond the Pain Battle', which focuses on the after - effects of the fight on the village and Naruto's relationships. There's also 'Naruto vs Pain: The Alternate Path' that takes a different turn in the fight's progression.
Well, 'Fractured Souls' is a great one. In this fanfiction, Hermione and Draco are both haunted by their own traumas which causes a lot of pain in their relationship. It's really interesting to see how they slowly start to understand each other's pain. Also, 'The Pain of Redemption' is quite good. It focuses on Draco's journey of redemption and how Hermione gets involved in it, and the pain they both experience along the way.
One interesting fanfiction could be where Naruto fully masters the powers of the Six Paths of Pain much earlier than in the original story. This could lead to him quickly overpowering his enemies and changing the course of the ninja world. He might use the abilities in unique ways, like combining the Deva Path's gravity control with his own shadow clone jutsu for some really cool battle strategies.
Another reason could be related to his relationships. Maybe in a fanfic, Naruto has a falling out with his friends like Sasuke or Sakura. This emotional hurt can be just as painful as physical harm. The author might use this to show how Naruto grows and overcomes such internal struggles.
One popular Naruto fanfiction is 'A New Path'. It focuses on Naruto exploring a different kind of ninja training outside of the village.

One common plot is that Hinata arrives at the crucial moment when Naruto is about to be defeated by Pain. She uses her Byakugan in a new and unexpected way to counter Pain's attacks. For example, she might be able to see a weakness in Pain's jutsu that no one else could.
I've also heard of a fanfiction that focuses on a battle between Fairy Tail and Pain. In this story, Pain uses his unique abilities in ways that challenge the Fairy Tail members like never before. It's a great read for those who like intense battle scenes and seeing how different power sets interact in the Fairy Tail world.
Archive of Our Own (AO3) is also a great place. It has a well - organized tagging system. Just search for 'Naruto' and 'Pain' tags and look for the ones that imply Naruto having positive feelings towards Pain. There are often some really creative works there.
