Naruto could encourage chaos in fanfiction through his unorthodox training methods. He might introduce new and wild ways of training that break the traditional mold. His friends and comrades, seeing this, would be intrigued and might start to deviate from the normal training routines, leading to a more chaotic and unpredictable environment in the ninja world of the fanfiction.
In some fanfictions, Naruto might encourage chaos by challenging the established order in the village. For example, he could question the strict rules and hierarchies that limit the freedom of the younger generation. This might inspire others to also think differently and cause a bit of chaos as they start to resist the status quo.
