Well, he might use some special jutsu or seals. Maybe he combines his chakra in a unique way to access all five elements simultaneously. For example, he could have a new form of Rasengan that incorporates all the elements.
Perhaps there is some kind of ancient prophecy or power within him that awakens the ability to control all five elements. He starts by having a basic understanding of earth, water, fire, wind, and lightning. Then, through a series of adventures and battles, he discovers how to blend these elements in harmony. He might learn from the spirits or sages in the fanfiction world who guide him on this journey of mastering all five elements.
In this fanfiction, Naruto could have trained intensively to master each element separately first. Then, with his strong will and determination, he figures out a way to merge them. It could be related to his Uzumaki heritage which gives him an edge in chakra control. He might use his shadow clones to practice different element combinations until he can control all five at once.
Well, it could completely reshape the battles. Instead of relying on just one or two main elements like wind in the original, he can now use a combination of all elements to outwit his opponents. For example, he could use water to douse an enemy's fire jutsu and then follow up with earth to trap them.
In certain fanfiction scenarios, it could be through some kind of ancient training method that was long forgotten. Naruto stumbles upon an old scroll or meets an old hermit who reveals to him the secrets of controlling all elements. So, his discovery is more of a guided, knowledge - based awakening rather than a spontaneous one.
Well, it could change the plot in many ways. For one, he might be able to defeat stronger enemies more easily. With the five elements at his disposal, he could use combinations of attacks that are unexpected. For example, combining water and fire to create steam - based attacks that could blind or disorient foes.
In this fanfiction, Naruto could control all the tailed beasts because of his unique chakra nature. His chakra is very special and has a high compatibility with the tailed beasts' chakra. Also, his experiences with Kurama might have given him insights on how to handle other tailed beasts. He probably communicates with them on a spiritual level and convinces them to work together with him.
Well, in many fanfictions, Naruto might use his strong will and the power of his Uzumaki heritage. His natural chakra reserves are huge, which helps. He also has a deep understanding of friendship and the tailed beasts' pain from his own experiences. So, he can connect with them on an emotional level and gradually gain their trust, thus being able to control them.
One interesting application is his ability to create entirely new jutsus by combining different elements. For instance, he could mix fire and wind to create a super - heated blast that's more powerful than either element alone.
Well, it could make some characters more in awe of him. For example, his friends like Sakura and Shikamaru might see him in a new light. They could rely on him more during difficult situations. And his enemies would probably be more fearful. They might change their strategies when facing him, knowing he has such a powerful ability.
Well, in many fanfictions, Naruto might start learning all elements through some unique encounters. Maybe he meets a powerful sage or a mysterious ninja who has knowledge of all elements and decides to teach him. It could also be due to some ancient scroll he discovers that holds the secrets of mastering all elements.
Well, in some fanfictions, Naruto might achieve this through intense training with powerful mentors. Maybe he travels to different hidden villages to learn from their unique elemental techniques. For example, he could go to the Mist Village to master water techniques. Another way could be through some kind of ancient power or a special inheritance that unlocks the ability to control all elements within him.
His having all sub - elements would likely shift the power balance in the Naruto universe. He could potentially solve problems more easily. For instance, if there's a natural disaster caused by an imbalance of elements, he could use his all - encompassing element powers to restore balance. This would change the overall narrative as he becomes a more central figure in maintaining the world's stability.
