Well, it could be that in the fanfiction world, Naruto's own chakra system has a latent ability to adapt to chaos energy. Maybe due to his Uzumaki bloodline which is known for its strong and unique chakra, his body is able to gradually assimilate chaos energy. He might start by unknowingly absorbing small amounts during intense battles or in places where chaos energy is concentrated, and over time, learn to control and use it for various purposes like enhancing his speed or creating new jutsu.
In some fanfictions, Naruto might be able to use the Chaos Release through a special training or encounter. Maybe he meets a powerful being who imparts the knowledge of this unique release to him, allowing him to access its power.

Well, in 'naruto chaos energy fanfiction', it might involve the concept of chaos energy disrupting the normal ninja world order.

There might be some popular 'naruto chaos energy fanfiction' stories out there. However, popularity can vary depending on the community.

In fanfiction, Naruto may also use chaos energy for defensive purposes. He could form a chaos - energy - based shield around himself.

Some fanfictions might play with the idea of alternate universes. In an alternate universe, the rules of ninjutsu are different.

Naruto could start as a naive and impulsive character who causes chaos without really meaning to. But as the fanfiction progresses, he could learn from his mistakes.
