Well, it could be that they have different demands that aren't being met. Maybe it's related to their missions or the way they're treated. There could be a lot of reasons!
You should focus on the energy and chakra control needed for creating and maintaining the clones. It's all about balance and not overexerting yourself.
Well, in Naruto fanfiction, using shadow clones in orange animals might involve channeling chakra and imagining the desired effect. It could be a creative twist specific to the fanfic's world-building.
One interesting storyline could be a fanfic where a character uses shadow clones to explore different paths in life simultaneously. For instance, one clone might pursue a path of strict ninja training, another could focus on learning about the village's history, and the original character gets to experience the knowledge and skills gained from all these different 'lives' of the clones.
They can add chaos. For instance, if Naruto sends his clones to do different tasks in a lemon - themed fanfic, like helping at a lemonade stand in the village. But the clones being clones, they might overdo things, like making too much lemonade and flooding the area. This creates a comical and engaging plot point.
Well, such a story usually emerges when women feel their rights or demands aren't being addressed. It's a powerful symbolic act to make a point and bring about social awareness and possible reforms.
A third plot idea is a character - swap scenario. What if Kojou Akatsuki wakes up in the Naruto world with his vampire powers? He would have to navigate the world of ninjas, clans, and hidden villages. Meanwhile, Naruto could end up in the Strike the Blood world, having to deal with the complex politics between the different vampire factions while also trying to find a way back home.
Sasuke could also be an interesting crossover character. In the Strike the Blood world, his Sharingan and ninja skills would make him a formidable opponent. He could cross paths with the powerful vampires and might even form an uneasy alliance with some of them. His quest for power could take on a new dimension in this different universe.
The information you provided is not detailed enough for me to give an accurate answer. However, according to your description, this novel might be The Clone Wars (The Clone Wars:A Story of the Clones). It was a novel about a world war between clones. The war started in Brazil.
