Naruto would likely win. Godlike Naruto implies he has extraordinary powers. Naruto has strong chakra reserves, and his signature jutsus like Rasengan are extremely powerful. Also, his ability to quickly adapt in battle gives him an edge over Orochimaru.
Perhaps he uses some ninja techniques like a shadow clone jutsu. He could make multiple clones to help him sort through and complete the paperwork quickly.
He could have the power to instantly heal any injury. His chakra might be so vast that he can create multiple clones without getting tired. Also, he might be able to control the elements in ways that are beyond normal shinobi capabilities.
I really like 'Naruto, Sasuke and Sarutobi: A New Beginning'. In this fanfic, it starts with Sarutobi having a premonition about the future of Naruto and Sasuke. So he takes steps to guide them differently. It's an interesting take on their relationship. 'Sasuke's Redemption under Sarutobi' is also good. It shows Sasuke trying to make amends with the village with Sarutobi's guiding spirit in mind. And 'The Hidden Power of the Trio' is a fanfic that gives a new perspective on the powers they possess and how they can be combined for the greater good.
A common theme is family and clan loyalty. Since the Sarutobi are an important clan in the Naruto universe, many OC fanfictions explore how the original characters uphold the values and traditions of the clan. Another theme is the pursuit of power. OCs often strive to become strong ninjas, just like the well - known Sarutobi characters in the original series.
In this type of fanfiction, it's possible that the story delves into Naruto's backstory and how being Sarutobi's son would have affected his childhood. Maybe he would have grown up with more guidance and support, which could have changed his personality. Instead of being the lonely outcast that he was in the original story, he could have been more confident from the start. The fanfiction might also introduce new characters related to Sarutobi that play important roles in Naruto's life. There could be new adventures and challenges that are unique to this new family dynamic, such as Naruto having to uphold the Sarutobi family name and legacy within the Hidden Leaf Village.
Well, it could be about Naruto getting special training from Sarutobi in stealth. Maybe Sarutobi teaches Naruto some ancient jutsu that only he knows. This would give Naruto an edge in battles and make him more respected in the village.
One possible fanfiction could be about an OC (original character) who is a student of Hiruzen Sarutobi. This OC has always heard tales of Minato Namikaze's heroics. The story could involve the OC getting into a difficult situation, perhaps a dangerous mission, and drawing inspiration from the skills and courage of Minato. Hiruzen, as the wise teacher, could guide the OC in learning from Minato's example. For example, the OC might be struggling with a new jutsu, and Hiruzen tells them how Minato mastered a similar one with his determination and innovation.
One great Anbu Naruto Sarutobi fanfiction is 'The Anbu's Hidden Mission'. It delves deep into Sarutobi's leadership within the Anbu and Naruto's unexpected role in a secret operation. The story is filled with intense action scenes and a touch of mystery.
