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.
One strange power Naruto might possess in fanfiction is the power of elemental fusion. Instead of just using one type of elemental jutsu like fire or water, he could combine them in unique ways. For example, creating a jutsu that combines lightning and earth to make a powerful, electrified earthen attack. He could also have the power of astral projection, where his spirit can leave his body and travel to different places, either for spying or for learning secret techniques from distant masters.
He could have the power of contagion. Naruto might be able to spread a weakened form of the virus to his opponents, which could slow them down or disrupt their chakra flow. Another possible power is enhanced adaptability. The virus in his bloodline could make his body adapt quickly to different situations or attacks, like developing immunity to certain jutsus.
Some fanfictions might give Naruto the power of elemental fusion. He could combine fire, wind, water, earth, and lightning in ways that are not possible in the original series. This would make his attacks extremely powerful and unpredictable. For instance, he could create a storm of lightning - infused water that not only electrocutes his enemies but also drowns them.
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.
One possible power is enhanced speed. Sparda is known for his agility in combat, and Naruto as his descendant in fanfiction could inherit this. He would be able to move so fast that his opponents could barely keep up. Another power could be the ability to manipulate demonic energy in a way similar to how he manipulates chakra. This could give him new jutsu - like abilities, for example, creating energy blasts with demonic properties. He might also inherit Sparda's resistance to certain types of attacks, like magic or dark energy attacks that are common in the Devil May Cry universe.
He could have the power of instant regeneration. So, no matter how severe the injury, Naruto could heal himself in a split second. This would make him extremely difficult to defeat in combat.
Well, it could be something like the ability to control elements in a completely new way. For example, instead of just the basic five elements in Naruto, the new bloodline might allow for the manipulation of light or dark energy. Maybe it gives the power to teleport short distances instantly, which would be a huge advantage in battles.
Maybe Naruto's death powers are a result of some ancient curse or a powerful jutsu gone wrong. This could lead to a plot where he has to find a way to reverse it, while also using it to protect his village. He might encounter other shinobi who have similar powers and learn from them how to use it more effectively.
One possible new power could be the power to absorb and use any chakra, regardless of its origin. This would make him extremely powerful as he could draw from the chakra of his enemies or even from natural sources like the sun or the earth. He could also gain the power of telepathy on a large scale, being able to communicate with anyone in the world or even across different dimensions. Additionally, he might obtain the power of instant teleportation to any place he desires, which would give him a huge advantage in battles and travels.
He could have the ability to fly by using sonic waves to propel himself. Just like how some characters in other stories use sound to levitate. Another cool ability would be to create sonic shields. These shields could protect him from attacks by vibrating at a high frequency and deflecting incoming projectiles.
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.
