In some Naruto fanfictions, Naruto's chaos powers might be shown as a wild and unpredictable energy source. It could make his jutsu more erratic but extremely powerful. For example, his Rasengan might become a chaotic, swirling mass of energy that can break through even the strongest defenses with ease.
In some fanfictions, the chaos powers might come from an encounter with a powerful and mysterious entity. This entity could have bestowed these powers upon Naruto, either as a gift or as part of a greater plan. For example, a powerful spirit from an ancient realm might have seen Naruto's potential and decided to give him these chaos powers to help him in his journey.
In this fanfiction, the prototype powers could be something like an early form of chakra manipulation that is different from the traditional Naruto world's chakra use. It might be more raw and unrefined, with the potential for new and unique jutsu.
Maybe chaos has the power of transformation. It could change the appearance or nature of things. For instance, it could turn a peaceful forest into a desolate wasteland or a simple object into a complex, magical item. Since Percy is its father, there might be some connection between Percy's own powers and these abilities of chaos.
His hidden powers might be the ability to control all five basic nature types without any training. In the original story, Naruto had to work hard to master different nature types. But in a fanfiction, it could be that he has this innate ability which was hidden all along. This would make him extremely powerful and feared by his enemies.
In some fanfictions, Naruto's multiverse powers are portrayed as a way to bring together different versions of himself. Each version has its own set of skills and knowledge. By merging these aspects, he becomes an even more powerful and complex character, able to solve problems that were previously insurmountable.
Well, he could use Freddy's power of entering people's dreams to fight his opponents in the dream realm. Maybe he would trap his enemies in a never - ending nightmare, causing them mental distress and weakening their will to fight in the real world.
Well, Naruto has his chakra and various jutsu. In fanfiction, his chakra could be seen as a form of magic in the Fairy Tail world. A chaos mage might have the ability to manipulate and disrupt this chakra - magic. For example, Sasuke's Sharingan could be used to analyze the chaotic magic of the chaos mage and find weaknesses, while Fairy Tail wizards use their own elemental magic to support Naruto characters in battles against enemies influenced by chaos magic.
He could have enhanced physical abilities. Since yokai are often known for their strength and speed, as the King of Yokai, Naruto might gain even greater strength and faster reflexes. He may also have the ability to communicate with all types of yokai, understanding their languages and thoughts, which would give him an edge in dealing with them.
Well, Naruto would become extremely powerful. He could use Sinbad's magic powers along with his own ninja skills. Maybe he could fly around the Hidden Leaf Village like Sinbad on his magic carpet and use his powers to protect the village in ways he couldn't before. It would be a really cool combination.
