Well, in Naruto fanfiction, the Kyuubi often has the power of destruction. It can unleash huge amounts of raw chakra that can level mountains or create massive shockwaves. The Kyuubi's power can also be used for healing in some fanfictions. Since it has such a large amount of chakra, it can be used to heal the jinchuriki's wounds, even from near - fatal injuries. Also, in certain fan - made stories, the Kyuubi has the ability to communicate telepathically with the jinchuriki, providing wisdom and knowledge from its long existence.
Psychic powers in Naruto fanfiction can also be given to other characters. For example, Sakura could have psychic powers that allow her to predict an opponent's moves more accurately.

Well, in 'Naruto Powers of a God' fanfiction, Naruto may possess god - like powers like the ability to resurrect the dead. He could bring back all the fallen comrades from the Great Ninja Wars.

Maybe through some kind of special training or a unique ritual. It could be that he discovers a hidden method within the ancient scrolls of his village.

It's a common trope in fanfiction to use such magical or mysterious items to bring about extraordinary power combinations.
