Naruto might also have some sort of mind - control or illusion - based powers. Jenova has been known to influence minds in some storylines, so Naruto could use this to his advantage in battles or to manipulate situations. For example, he could create illusions that are so realistic that his enemies can't tell the difference. This would be a great addition to his existing ninja skills.
I'm not sure of the exact name, but there's a fanfiction where Naruto's connection to Jenova is a secret at first. As the story progresses, he discovers more about his origin and has to deal with the implications. It's an interesting take as it shows Naruto's growth not just as a ninja, but also in coming to terms with his strange heritage.
He could have the power of light. Maybe he could create blinding flashes to disorient his enemies. Also, he might be able to control the sun's heat, using it in combat like shooting out beams of intense heat.
Naruto's chakra powers could potentially counteract Jenova's invasive and corrupting abilities. His positive and life - giving chakra might be able to purify areas affected by Jenova. For example, if Jenova spreads its cells to take over a region, Naruto could use his Rasengan, charged with his pure chakra, to destroy those cells.
He could have the power of flight. It's a common ability associated with angels, and it would give Naruto a huge advantage in battles and also in getting around quickly.
He could have the power of flight, which is a very common ability associated with dragons. This would give him an advantage in battles and also make traveling much easier.
He might have super strength like Optimus Prime. This would allow him to do things like punch through solid rock or lift extremely heavy objects. Also, he could have the ability to transform parts of his body into robotic parts for added protection or combat advantage.
Well, first of all, Naruto's power of sensing chakra might be enhanced to sense ki as well. His shadow clone jutsu could potentially be combined with ki clones, creating a whole new level of clone - based attacks. His original wind - style jutsu could be infused with ki energy, giving them a different color and more potency. And instead of just using the Nine - Tailed Fox's chakra for power - ups, he could have some sort of transformation related to his Saiyan heritage from Goku Black. This would not only change his appearance but also boost his overall combat abilities far beyond what he could do in the original Naruto series.
In fanfiction, Naruto could have the power to control time. He might be able to freeze time during battles, giving him an edge over his opponents. Another strange power could be the ability to communicate with all living things. This would allow him to understand the thoughts and feelings of animals and plants, and use this knowledge to his advantage in various situations.
He might have the power of instant teleportation. Just like a god can appear anywhere, Naruto could do the same to surprise his enemies or reach his friends in need quickly.
He might have the power of Odin's All - Father magic. This could allow him to see the past, present, and future, just like Odin's ability to gain wisdom through his ravens. Also, he could potentially have enhanced physical strength, much greater than what he has as a regular ninja, allowing him to overpower even the toughest opponents with ease.
