It could also be for combat support. In battles, the robot army can assist the ninja. They can be used to create distractions, carry heavy weapons, or even perform coordinated attacks with the ninja. Their mechanical nature might give them an edge in certain situations, like being resistant to some types of jutsu.
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 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.
Sasuke might be initially suspicious. He would question Naruto's motives and the potential danger of such an army. But after seeing how Naruto uses it for good, he might come to accept it.
It could be Orochimaru. He's always been into strange experiments. He might create a robot army to get revenge on the village or to prove his superiority.
Maybe Naruto creates the robot army as a way to bridge the gap between the ninja villages. He uses them for peaceful purposes like construction and rescue operations at first. But then, a rogue group tries to steal the robots and use them for evil, so Naruto has to fight to protect his creation. Well, in this fanfiction, the robots could be powered by chakra, which gives them an interesting twist. They might also be able to learn ninja techniques from Naruto and the other ninjas, making them a formidable force not just in terms of brute strength but also in combat skills.
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.
Robot Naruto in RWBY fanfiction would probably have some amazing abilities. He could have super - strength, allowing him to lift heavy objects or overpower Grimm easily. His robotic body might also give him the ability to transform, like changing his arms into weapons or his legs into boosters for faster movement. Additionally, he could have some sort of energy projection, like shooting lasers from his eyes or hands.
Well, Naruto himself would probably be really excited. He'd be running around the military base, trying to make friends with everyone. His positive attitude might initially seem out of place in the strict military environment but could also start to change the atmosphere, making it more lively.
Naruto could be a special ops agent. His agility and quick - thinking from his ninja training would make him perfect for dangerous and covert missions.
