A story could revolve around Naruto being the sole male survivor and having to deal with the psychological impact of it. He might struggle with feelings of loneliness and survivor's guilt. However, he uses these emotions to fuel his determination to keep the ninja way alive. He starts by mentoring young male orphans, teaching them the values of the ninja world. As he does this, he gradually builds a new community of male ninjas. This new community then faces challenges from within, such as power struggles and different interpretations of the ninja way, which Naruto has to navigate.
One possible storyline could be about Naruto having to rebuild the ninja world with only male comrades alive. He might focus on training the next generation of male ninjas in a more intense and unique way, incorporating his own experiences. For example, he could create a new training regime inspired by his time with Jiraiya. Another idea is that the male survivors form an all - male alliance to face new threats that emerge in the absence of female ninjas, with Naruto as the leader. They would have to adapt and develop new strategies without the skills and abilities that the female ninjas usually bring.
The main antagonists could be a group of rogue male ninjas who oppose Naruto's vision of rebuilding the ninja world. They might believe in a more ruthless and power - hungry approach, seeing the situation as an opportunity to take over. Another possibility is that an ancient evil, sealed away long ago, is released due to the imbalance in the ninja world with only male ninjas alive. This evil entity could be extremely powerful and have motives related to destroying the new order that Naruto is trying to establish.
Well, in this 'Naruto Only Male Alive' fanfiction, perhaps Naruto wakes up one day to find only male ninjas around. He then decides to create a new ninja order. He starts by training the younger male ninjas more rigorously, teaching them not just combat skills but also the importance of unity. As he does this, he uncovers secrets about a prophecy that only a male ninja can fulfill in this strange new world, and he has to rise to the occasion.
One possible storyline could be that Naruto's parents, Minato and Kushina, are alive and they train Naruto from a young age. This would make Naruto an even more powerful ninja earlier on. He would grow up with their love and support, and perhaps not be as much of an outcast in the village as he was in the original story.
He could have the power of energy absorption. So, when an enemy attacks him with a jutsu, he can absorb the energy and use it to strengthen his own attacks. It would be like a reverse - engineering of the attacks against him.
Danzo could be a great antagonist. He was always a bit of a shadowy figure in the Naruto series. In this 'Only Male Alive' fanfiction, he might emerge as a dictator - like figure. He could be trying to enforce his strict, often controversial rules on the remaining male ninjas, seeing Naruto as a threat to his new - found power and control.
In this fanfiction, Naruto could have the ability to sense and manipulate male - like aspects of chakra even if they don't exist in other male users. For instance, he might be able to tap into some primordial male chakra energy that was thought to be lost. This could give him the power to do things like heal in a different way or communicate with ancient chakra entities that are only attracted to male chakra, making his character much more interesting and his abilities truly one - of - a - kind.
One possible storyline could be that Minato and Kushina help Naruto train. They could pass on their unique jutsu and combat skills directly to him. This would make Naruto even more powerful at a much faster rate compared to in the original story.
A fanfiction storyline could be that Naruto's mother is alive and she reveals to Naruto secrets about his father, Minato, that no one else knew. This could lead to Naruto having a different perspective on his father and his own role in the village. Also, Kushina could be part of a secret organization within the village that is dedicated to protecting ancient shinobi secrets, and she brings Naruto into this world of mystery.
One interesting story could be about the origin of Naruto's ability to summon demons. In the fanfiction, it could be revealed that it was a long - lost bloodline ability that was sealed away for generations. As Naruto discovers this, he has to deal with the fact that there are those in the ninja world who want to use this power for evil. He then has to protect this secret and use his newfound ability to summon demons to stop those who would misuse it, all while trying to understand the true nature of his connection to the demon world.
One possible storyline could be that with his parents alive, Dark Naruto might not have turned so dark in the first place. His parents' love and guidance could have steered him away from the path of darkness. For example, Minato, being a powerful ninja, could have trained Naruto properly from a young age, and Kushina could have provided the emotional support he needed. This would change the whole dynamic of the Naruto universe as we know it, and there would be no need for him to seek power in dark ways.
