One possible plot development could be Naruto focusing on rebuilding Konoha. He might use his newfound influence and power to inspire the villagers and make Konoha stronger than ever. Maybe he starts new training programs for the ninja of the village to better prepare them for future threats.
Naruto himself is obviously a central character. His growth and decisions will shape the story. Hinata could also be important as her relationship with Naruto might develop further. Shikamaru, being one of Naruto's smartest friends, could play a crucial role in planning for Konoha's future and strategizing against potential threats.
I'm not sure which is the absolute best, but 'Naruto and the Spectacle of Pain's Battle' is another one that stands out. It has some unique interpretations of the fight, like how Naruto analyzes Pain's techniques in real - time and how that affects his own future battles. The writing style is engaging and it keeps you hooked from start to finish.
Boruto is often a popular character as he is the main character in the new generation. His journey to find his own path separate from his father Naruto's is an interesting aspect. Sasuke also remains popular as his skills and complex personality continue to draw readers.
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.
You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide range of Naruto fanfictions, and you might be able to find one about Naruto watching the fight with Pain there.
The biggest difference is the creativity of the fanfiction writers. In the anime, the fight follows a set storyline. But in fanfiction, anything can happen. For example, Naruto could suddenly gain a new power that was never in the anime. It's like a whole new world of possibilities.
Often, Naruto's relationships with other characters are explored further. He might have deeper conversations with Sasuke, trying to convince him to come back to the village for good. His bond with Sakura could also develop in different ways, perhaps becoming a stronger friendship or even something more romantic in some fanfictions.
In some fanfictions, after Naruto defeated Pain, the village started to rebuild immediately. Naruto became a hero not only in name but also in the hearts of every villager. People looked at him with newfound respect and admiration.
