The plot could center around the first male ninja facing some great threat to the ninja world. He might be on a quest to find a powerful jutsu or artifact to save everyone. Along the way, he could encounter various challenges, make new friends and enemies, and his character could develop as he overcomes these difficulties. For example, he could start as a novice and gradually become a respected and powerful ninja.
In this fanfiction, Naruto could be given god - like speed, strength, and intelligence. Since he is the first male ninja with these powers, he decides to rewrite the rules of ninjutsu. He might start training other ninjas in a new way that focuses on inner power rather than just physical techniques. This could lead to a revolution in the ninja world where Naruto is seen as a pioneer and a hero.
It could entail the first male ninja's struggle to gain acceptance in a world that might be dominated by different power structures initially. Maybe he was from a small village and had to prove himself against bigger, more established ninja groups.
Obviously, the first male ninja would be the main character. But there could also be his mentor, someone who guides him in his ninja training. Maybe an old and wise ninja who has a lot of knowledge about different jutsus.
The plot could revolve around an Amegakure ninja who is on a quest to find a long - lost scroll that contains powerful jutsu. This ninja has to brave dangerous terrains and face off against other ninjas who also want the scroll. Maybe they have to team up with an unlikely ally, like a rogue ninja from another village, to succeed in their mission.
One possibility is that Naruto could become a diplomat. He has a big heart and a strong will, so he could use those traits to negotiate peace between different villages. Without being a ninja, he might focus on building relationships and using words rather than combat to solve problems.
One possible main antagonist could be an ancient evil ninja who was sealed away long ago and is now awakened by Naruto's new - found power. This antagonist might see Naruto as a threat to his plans of world domination and tries to stop him at every turn.
In this type of fanfiction, a cool plot twist could be that the Sound Ninja are not actually the bad guys. Naruto finds out that there has been a huge misunderstanding between the Leaf and the Sound. He then tries to bridge the gap between the two villages. Another idea is that Naruto is given a special mission by the Sound Ninja that has something to do with a powerful artifact hidden in Konoha. And the last one, what if Naruto is part of a prophecy in the Sound Ninja village that foretells of a great hero coming from outside their village to save them from a looming disaster?
A Naruto fanfic focused on the first male ninja could explore many unique aspects. For example, it could delve into the origin story of male ninjas in the Naruto universe. Maybe it would show how the first male ninja developed his skills, like mastering chakra control in a different way compared to later generations. It could also explore his relationships with other early ninjas, whether they were friends or rivals.
Well, one possibility is that Naruto feels betrayed by the Hidden Leaf Village. Maybe they wrongly accused him of a serious crime. So, he decides to go rogue. He could then start traveling alone, using his skills to survive and avoid capture. He might also meet other outcasts who understand his situation.
Perhaps in the fanfiction, Naruto and Ino accidentally get involved in a criminal ninja organization. They initially think they are joining a legitimate group that's supposed to protect the village in a different way, but soon realize it's a front for illegal activities. They then have to work together to expose the organization from the inside without getting caught themselves.
