In a Fanfic Where Naruto Can't Use Chakra, What New Abilities Could He Develop?

He could develop some sort of psychic power that doesn't rely on chakra. This could be a power related to his willpower, allowing him to influence the minds of his opponents or sense their intentions from a distance.

He could develop the ability to combine the power of the Sharingan with the Nine - Tails' chakra. Maybe he could use the Sharingan to better control the Nine - Tails' power, for instance, seeing the flow of the chakra inside him more clearly. This could lead to new jutsu that are a fusion of Uchiha and Uzumaki techniques.

He could develop the ability to use the Six Paths Sage Mode more effectively. Since the Rinnegan is related to the Sage of Six Paths, it would enhance his connection to that power. He might also gain the ability to create chakra chains similar to those of the Uzumaki clan but with an added Rinnegan - powered twist.

He might rely on his physical strength and martial arts skills. Just like Rock Lee in the original series who doesn't have much chakra but is a great fighter through intense physical training.

He would become more reliant on his friends and allies. Since he doesn't have chakra to fall back on, he has to trust others more and learn to work in a team in a different way.

Naruto could potentially have the ability to create ki - based shields. These shields could protect him from various attacks, whether they are physical or energy - based. Another new ability could be ki - infused clones. Instead of just normal clones made of chakra, these clones would have an added ki element, making them stronger and more durable. He might also be able to use ki to heal himself faster, similar to how some characters in other stories use life - force energy for regeneration.

He could develop the ability to use the Preta Path more effectively. This path allows the user to absorb chakra, and Naruto could use it to nullify enemy attacks that rely on chakra. For instance, if an enemy uses a powerful fire - style jutsu that is chakra - based, Naruto could absorb the chakra of the attack, rendering it useless.

One new ability could be enhanced physical combat skills. Tsunade's strength gives Naruto the power to deliver more powerful punches and kicks, which could be a game - changer in close - quarters battles. He might also develop the ability to use medical ninjutsu more effectively. Since Tsunade is a master of it, Naruto could learn to heal himself and others faster during battles, adding a new dimension to his fighting capabilities.

One new ability could be the power to charge his own body with kinetic energy for enhanced physical attacks. He could deliver punches or kicks that explode on contact, similar to Gambit's charged staff strikes. Another ability would be to create energy barriers by rapidly charging the air around him. This would be a great defensive move, something Naruto currently lacks in his regular skill set. He could also potentially use Gambit's power to sense the energy levels of his enemies from a distance, giving him an advantage in strategizing his attacks.

He could develop the ability to better withstand the different climates in One Piece. Since he's immortal, he might experiment with his body in ways others can't. Maybe he could learn to breathe underwater like a fish - man over time due to his long - lasting life.
