No, it is not ethical. Naruto is a popular and often beloved character in the anime world, especially among younger audiences. Creating such inappropriate fanfiction goes against the spirit of the original work which is mainly about friendship, growth, and ninja adventures. It also involves creating non - consensual and inappropriate scenarios for a character which is unacceptable.
Some great topics would be Naruto's exploration of new jutsus. He could be on a journey to discover ancient ninja techniques that have been lost. Or, the story could focus on his family life, like how he raises his children to be strong and kind - hearted ninjas. Team - building adventures with his old friends and new comrades are also good topics.
Perhaps it's for exploration. Naruto is always curious about the world outside. The robots can be sent to explore dangerous or uncharted areas where it might be too risky for humans to go. They can collect information and report back to Naruto.
Maybe Naruto has some knowledge from an unexpected source. For example, he could have met a wandering inventor who taught him the basics of robotics. With his determination and quick learning ability, he then starts building the robot army. He might also use his chakra in some unique way to power or control the robots.
Perhaps Naruto makes the robot as a tool to help around the village. It could assist in construction, or in taking care of the elderly and the young. Since Naruto is always looking out for the well - being of his village, a robot could be a great addition.
At first, Naruto might be a bit cautious. He's used to facing opponents in battle, and a strange new object like a robot could potentially be dangerous. But once he realizes it's not an immediate threat, he'd likely approach it with his usual enthusiasm. He might start asking it all sorts of questions, like 'What are you?' and 'Where are you from?' His reaction would be a mix of excitement and wariness.
The plot might involve Naruto making the robot to replace himself when he's away on long - term missions. The robot would look like him and act like him, but it would have some glitches at first. These glitches could lead to some comical situations in the village, like the robot accidentally using a powerful jutsu in the middle of the market. As the story progresses, Naruto works to fix the glitches and make the robot a reliable substitute.
Well, Naruto is the central figure for sure. But other characters like Kakashi could also be important. He might be the one guiding Naruto through the process of adapting to his new robotic body. And then there could be new characters introduced, perhaps other half - robot ninja created by the same process as Naruto, and they could either be friends or foes.
Perhaps in the fanfiction, the robot army is a result of some mad scientist's experiment in the Naruto universe. Naruto and his friends have to figure out the weaknesses of these robots, which could be related to chakra or some specific ninja techniques. They might also encounter some robots that can copy ninja abilities, adding more challenges to the story.
Well, one possibility is that Naruto is turned into a robot by some kind of advanced jutsu gone wrong. He might then struggle to adapt to his new mechanical form. For example, he could find it hard to perform his regular ninja moves in the same way. Maybe he would initially be rejected by his friends until they realize his inner self is still the same Naruto they know and love.
