His fighting style would likely become more defensive. The metal armor could act as a shield, allowing him to block attacks more easily. He might also use it for more physical combat, like charging at enemies and using the armor's weight and strength to his advantage.
Naruto's fighting style would change significantly. With the metal armor, he could potentially have a more grounded approach. Instead of relying solely on his speed and ninjutsu, he could use the armor's durability to withstand powerful attacks. He might also develop new jutsu that are specifically designed to work with the armor. For example, he could create a jutsu that channels his chakra through the armor to create a shockwave. This would not only be a new offensive ability but also a way to keep enemies at a distance. Additionally, the armor could give him a more intimidating presence on the battlefield, which could psychologically affect his opponents.
If Naruto had metal armor in a fanfiction, his fighting style would change in several ways. Firstly, he could incorporate the armor's unique features into his attacks. For instance, if the armor had spikes, he could use those in close - range combat. Secondly, his movement might be restricted a bit, so he would have to develop new ways to be as agile as before. He could use chakra to enhance his movement while wearing the armor. Also, he could use the armor as a distraction. For example, he could make it shine brightly to blind his opponents momentarily before launching an attack.
Naruto's fighting style would likely become more focused on close - combat. Spartan armor is designed for hand - to - hand and melee combat. So he might rely less on his long - range ninjutsu and more on using his fists, a Spartan - style shield, and a short sword if the armor comes with those. He would also probably become more defensive, using the armor's protection to his advantage and waiting for the right moment to strike.
It could also change his offensive style. Naruto might be able to channel his chakra through the armor to create more powerful rasengan variations. The black lightning could add an extra element of destruction to his attacks.
His fighting style would likely incorporate more acrobatic moves. Since the Keyblade can be used for things like jumps and dashes in mid - air, Naruto would start using these abilities. He might also use the Keyblade to block attacks more effectively than he could with just his kunai or shuriken. And he could use the Keyblade's power to enhance his speed, allowing him to quickly close the distance between him and his opponents or dodge attacks more easily.
His fighting style would become more versatile. Naruto is used to his shadow clones and Rasengan techniques. But with Samehada, he could add a whole new dimension. Samehada absorbs chakra, so Naruto could use it to drain his opponents' chakra during close combat. He might also be able to combine his own chakra with Samehada's absorption ability to create some unique attacks that are more about disabling the enemy's chakra system rather than just physical damage.
His fighting style would become a blend of his original ninja techniques and the powers of Hyourinmaru. Naruto could use his clones to distract opponents while he uses Hyourinmaru to strike from unexpected angles. The ice powers would give him an advantage in certain terrains, like frozen landscapes. He would also have to learn to control the release of Hyourinmaru's power, which is different from his chakra control. This would lead to a more diverse and unpredictable fighting style.
Naruto could combine his Shadow Clone Jutsu with Stormbreaker. He could create clones to surround his enemies and then use Stormbreaker to launch a powerful attack from the center. This would be a new and unexpected tactic for his opponents. Also, he might use his chakra to enhance the power of Stormbreaker even further, like making it shoot out energy blasts.
His fighting style might also become more strategic. Since the Amaterasu Zanpakuto is a powerful weapon, Naruto would need to think about when and how to use it. He might use his regular ninjutsu to distract his enemies first and then surprise them with a swift strike from the Zanpakuto. Also, he could use his clones to set up a formation where the Zanpakuto's power can be maximally utilized, like having clones surround an enemy and then all attack with the Amaterasu - infused Zanpakuto at once.
His fighting style would change in terms of strategy too. With the power armor, Naruto may not need to rely as much on his shadow clones. Instead, he could use the armor's defenses to withstand powerful attacks while he focuses on delivering more direct and powerful strikes. He might also use the armor's advanced sensors to detect hidden enemies or traps, changing the way he approaches a fight scene completely.
Naruto's fighting style would likely incorporate more acrobatic flips and spins to take advantage of the lightsaber's reach. He'd also use his shadow clone jutsu in new ways, like having clones surround an enemy while he attacks from above with the lightsaber.
His fighting style would likely become more melee - focused. Naruto is used to fighting from a distance with his jutsu, but with Zabuza's sword, he would need to get up close and personal. He might start to combine his ninjutsu with sword strikes. For example, he could use a clone to distract an enemy while he closes in with the sword for a surprise attack.
