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.
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.
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.
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.
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, 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.
One possibility is that Naruto's transformation into a robot could change his relationships. His friends might be initially shocked and have to learn to trust this new robotic version of him. He could also face new enemies who are specifically targeting him because of his unique robotic - ninja nature. His sensei might have to train him in different ways to make use of his robotic abilities, like teaching him how to maintain and upgrade his robotic parts.
The robot arm often serves as a symbol of change and growth in these fanfictions. For example, Naruto might have to adapt to this new limb, which could represent his evolution as a character. He has to learn new fighting styles and ways of interacting with the world around him. Also, the robot arm can have unique powers that are different from traditional ninjutsu, like the ability to interface with machines or have super - strength. This opens up new plot possibilities and challenges for the characters.
