In most cases, it's not ethical. The Kage Bunshin is a powerful jutsu in the Naruto universe. Abusing it goes against the principles of fair use of power. In fanfiction, while there's creative freedom, if Naruto is made to abuse this jutsu, it can distort the essence of his character. He is generally seen as a hero who uses his powers responsibly, so such an abuse in fanfiction might not sit well with many fans who have a strong connection to the original portrayal of the character.
Well, it could be about various things. Maybe it's a fanfiction centered around Naruto's Shadow Clone Jutsu (bunshin) and some kind of big explosion (daibakuha). It might explore a scenario where Naruto uses his clones in a unique way to create a powerful explosion in a battle, or it could be a more creative take on how this jutsu affects the story's plot and the characters around him.
There might be some out there, but it's not a mainstream or typical Naruto fanfiction theme. Naruto fanfiction usually focuses on things like battles, character relationships in a more traditional sense, like friendships or romances between existing characters. The idea of a bunshin (clone) getting pregnant is quite out - of - the - box and might be considered inappropriate or just not in line with the general tone of most Naruto - related stories. So, while it's possible, it's not likely to be easy to find.
One idea could be a fanfiction where Naruto's bunshin have their own unique personalities that develop over time. They could start to have different goals and desires from the original Naruto, leading to some interesting conflicts within the story.
One possible consequence could be that Naruto himself loses control. Since the Kage Bunshin requires chakra, overusing it through abuse might lead to him depleting his chakra reserves dangerously. Another consequence could be that his relationships with others suffer. If he uses the clones in an improper way, like sending them to spy on his friends, it would break the trust among them.
In early fanfiction, Naruto's kage bunshin training was often depicted as intense. He would create a large number of clones and have them perform various tasks. Some fanfictions showed him using the clones for stealth training, where they would sneak around undetected. Others might show the clones practicing complex jutsu combinations, with Naruto himself observing and learning from their attempts.
In early fanfiction, Naruto's kage bunshin training was significant as it was a key part of his growth. It allowed him to practice techniques more efficiently. Since the kage bunshin can retain knowledge, Naruto could learn at an accelerated pace. For example, he could send clones to study different jutsu while he was doing other things, like physical training. This made him a more formidable ninja over time.
To start writing Naruto bunshin fanfiction, think about the purpose of the bunshin in your story. Are they created accidentally? Or are they part of a grand plan? You can then begin to write the opening scene, perhaps starting with Naruto creating the bunshin and something unusual happening right away. This will hook the readers and make them want to read more. As you write, keep in mind the rules of the Naruto universe so that your fanfiction feels like it belongs in that world.
It could be an original character created specifically for the fanfiction. This character might be someone who was initially not very good at ninjutsu but discovers a special affinity for the kage bunshin technique and then devotes themselves to mastering it.
One interesting concept could be the unique ways the kage bunshin technique is used. For example, the main character might use it not just for combat but also for learning at an accelerated rate. They could send clones to different places to gather information simultaneously, like to different ninja villages to spy on their training methods or upcoming events.
