In this fanfiction scenario, Naruto's battle strategies are revolutionized. He no longer has to worry about being countered by an opponent with an elemental advantage. He can use his newfound ability to control all elements to create unpredictable attacks. He could, for example, create a whirlwind of fire, water, and earth shards all at once. This would not only be extremely powerful but also very difficult for the enemy to defend against as they would have to deal with multiple elements simultaneously.
His battle strategies would change a great deal. Naruto is known for his diverse range of skills in the original series. But if he can only use Taijutsu, he'd likely start by observing his opponents more carefully. He'd need to analyze their fighting styles and look for patterns. Then, he'd use his own Taijutsu in a more calculated way. Maybe he'd combine different types of physical attacks, like a series of kicks followed by a powerful uppercut. He'd also have to work on his physical strength and endurance more, since he can't rely on other techniques to give him an edge.
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.
Naruto having all elemental affinities means he can adapt his battle strategy based on his opponent's weakness. If his foe is weak against water, he can quickly switch to water - based attacks. He doesn't have to rely on just one or two elements like other ninjas. This flexibility makes his battle plans more versatile and unpredictable.
Well, it could change a lot. For example, he might be able to prevent some of the tragic events that happened in the original. He could stop the deaths of his comrades like Jiraiya. He could also reshape the ninja world order more quickly, maybe by eliminating the root cause of the shinobi wars directly.
Well, Naruto's control over physics could completely turn the plot upside down. He could use it to create new jutsus that defy normal physical laws. For example, he might be able to make objects move without any force being visibly applied, which could give him an edge in battles. This new power would also make his enemies have to re - evaluate their strategies against him.
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.
When Naruto can control the bijuu in the fanfiction, his relationships shift. His friends might be more protective of him as they know his power makes him a bigger target. The villagers who once shunned him could now either idolize him or be even more suspicious. And in the ninja world at large, other villages may try to form alliances with him more eagerly, while some might plot against him out of fear that he'll use the bijuu to dominate. Naruto's newfound control over the bijuu is like a catalyst that stirs up all kinds of reactions in his relationships.
His combat abilities are enhanced greatly. With full control of the Kyuubi, Naruto can access its chakra more freely. This means he can enter the Nine - Tails Chakra Mode without the risk of losing control. His physical strength, speed, and endurance are boosted to superhuman levels. For example, he can move at incredible speeds, dodge attacks more easily, and deliver more powerful punches and kicks.
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.
Naruto's presence would likely introduce new tactics. His unique jutsus like the Rasengan could be used in unexpected ways. His opponents would have to adjust their strategies to deal with his unpredictable fighting style.
