What kind of powers might Naruto gain or lose in the fanfiction where he is brainwashed by Orochimaru?

He might gain enhanced physical strength like Bane. Bane was known for his brute force, so Naruto could have a similar boost, being able to overpower his opponents more easily in hand - to - hand combat.

Another possible power is the ability to control all the elements with extreme proficiency, not just the ones he already has in the original series. He could combine them in ways never seen before, creating powerful and unique jutsus that could defeat any opponent.

Naruto could potentially gain the power of infinite chakra. Since the Ten - Tails is a source of massive chakra, absorbing it may give Naruto an unending supply, allowing him to use high - level jutsu continuously without getting tired.

He might gain the power of omnipotence. Just imagine, he could be able to control all the elements at will, not just the ones he already knew like fire, water, etc. He could also have the power to teleport anywhere in an instant, which would make him an even more formidable opponent in battles.

He could gain super strength, allowing him to overpower enemies more easily than before. His speed would be enhanced to a level that might make him almost impossible to catch. And he could have the power of hypnosis, which would be useful in combat and getting information from foes.

Naruto's powers would be a strange mix. He could inherit Orochimaru's ability to regenerate, but in a more Uzumaki - style way. His rasengan could be infused with snake venom or some sort of snake - based chakra. And he might be able to use Orochimaru's body - switching jutsu in a modified form, perhaps using it not for evil but for strategic purposes in battles.

He could gain the power of controlling water like Poseidon's kids since he has good chakra control. It would be a new addition to his skill set.

He could have the power to instantly heal any injury. His chakra might be so vast that he can create multiple clones without getting tired. Also, he might be able to control the elements in ways that are beyond normal shinobi capabilities.

He might gain enhanced physical strength. The devil gene could give him a boost in his taijutsu skills, allowing him to overpower opponents more easily.

Well, in the fanfiction, it's possible that one of the sisters has a power related to the wind, just like Naruto. But instead of using it for offensive attacks mainly, she uses it for more defensive and utility purposes, like creating wind barriers or using the wind to carry messages. Another sister could possess a fire - based power. She could be a master of fire jutsu, creating intense flames that can melt metals. The third sister might have a unique power of light, being able to blind enemies or use light to create illusions.
