No. In fanfiction, there can be many male ninjas created by different authors. Fanfiction is a very creative space where various characters can be introduced.
The last male ninja might have a very different role in the village. He could be given special treatment, like being the first choice for all dangerous missions. This is because the village doesn't want to risk losing him as he's the last of his kind. However, this special treatment could also make him a target for enemies who see him as a valuable asset to capture or eliminate.
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.
His unique backstory. In fanfiction, Naruto's orphan status and his journey to gain recognition in the original Naruto story can be explored further or used in new and interesting ways. This makes him a distinct male ninja in fanfiction. Also, his powerful jutsu and his relationships with other characters, like Sasuke and Sakura, can be developed in different ways that set him apart.
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.
One interesting masked ninja is Shinji. He is a masked character in fanfiction who was once a normal ninja but got cursed by an ancient evil. Now, with his masked identity, he tries to find a way to break the curse while also using his new - found dark powers for good in the Naruto world. There's also a masked ninja named Yuki. Yuki is a snow - style user and her mask is made of ice crystals. She is on a quest to find the origin of her ice - based powers. Another is Hikaru, a masked ninja with the power of light, who is often at odds with the darker elements in the Naruto fanfiction world.
In a large number of fanfictions, Naruto is indeed portrayed as the strongest ninja. His journey in the original Naruto series gives him a solid foundation of power and growth. In fanfiction, authors can take this further. They can give him new jutsus, make his existing ones more potent, or enhance his physical and mental abilities. For example, he might master all types of chakra natures more quickly or have an even deeper connection with the Nine - Tails. This all contributes to making him seem like the strongest ninja in the fan - created narratives.
One possible fanfiction could be about a Naruto ninja who has a special mouth technique. Maybe it allows him to speak different languages and he uses this ability to communicate with various enemies and allies during a mission. He could be on a quest to find an ancient scroll that holds the secrets to enhancing his mouth - related jutsu.
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.
Perhaps in this fanfiction, the last male ninja is seen as a sort of anomaly. The ninja world, which was used to a balance of male and female ninjas, now has to adjust. Other ninja might view him with suspicion or even envy. He could be ostracized by some because they fear his power or the fact that he's the last of his kind. This could lead to him having to prove himself constantly, not just in battles but also in his day - to - day interactions with other ninjas.
