Well, in some fanfictions, Naruto might use his new and improved Rasengan techniques. He could combine his Sage Mode with the Rasengan to overpower the Fourth Raikage's lightning - based attacks. Maybe he also uses his quick thinking and the element of surprise, like suddenly changing the direction or nature of his attack when the Raikage least expects it.
One possibility is that Naruto uses his ability to connect with others on an emotional level. He might understand the Raikage's motives and fears, and use that knowledge to his advantage. For example, he could find a way to make the Raikage hesitate during the battle, and then quickly strike. Also, Naruto's experience from previous battles and his growth as a ninja would play a crucial role in devising a strategy to defeat the Fourth Raikage.
Maybe Naruto gains better control over the Nine - Tails' chakra. He can use it in a more precise way, like creating chakra arms made of Nine - Tails' chakra to grapple with the Raikage or block his attacks. This would give him an edge in close - combat situations against the powerful Raikage.
Perhaps he uses some ninja techniques like a shadow clone jutsu. He could make multiple clones to help him sort through and complete the paperwork quickly.
In many fanfictions, Naruto might use new jutsus or a deeper understanding of his own power. Maybe he taps into a more powerful form of the Nine - Tails' chakra and combines it with his Sage Mode in a unique way to overpower Pain.
The fanfic could show Fem Naruto training under the Fourth Raikage for a short period. This would be an interesting scenario as she would learn different techniques and ways of combat from him. It would also give the opportunity for some character development for both of them, as they get to understand each other's cultures and values better.
In a Fem Naruto and Fourth Raikage fanfic, the story could revolve around a tournament where they both participate. Fem Naruto, with her newfound femininity, might bring a different kind of charm and strategy to the battles. The Fourth Raikage, on the other hand, is known for his brute strength. Their paths cross during the tournament, and they end up forming an unexpected alliance to face a common enemy that threatens the balance of the ninja world.
Well, in some versions, Naruto might use his new and improved Rasengan techniques. He could have combined it with his Sage Mode powers to overpower Orochimaru. Maybe he also uses his quick thinking and the element of surprise, since Orochimaru is always so full of his own schemes.
Some fanfictions might depict Naruto as having a deeper understanding of the chakra system than ever before. He could have found a way to disrupt Madara's connection to the chakra source, or maybe he was able to use his own chakra in a way that nullified Madara's powerful jutsus. Also, Naruto's experience from all his previous battles might have led him to anticipate Madara's moves and strategies, allowing him to stay one step ahead and ultimately defeat him.
It could strengthen Naruto's relationship with Iruka. Since Naruto is the son of the fourth hokage, Iruka might see Naruto as an even more important part of the village and be even more protective. For example, he could be more involved in Naruto's advanced training.
In this fanfiction, it could be that Ash has a really good strategy. He might first make Gyarados use up a lot of its energy by making it attack Charmander's illusions or decoys. Then, when Gyarados is tired, Charmander can step in with its full power. Charmander could also use the environment to its advantage. Maybe there are some flammable objects around that can be set on fire by Charmander, creating a more powerful and widespread fire attack that Gyarados can't avoid.
In some fanfictions, Aang's connection to his past lives plays a crucial role. He could draw on the wisdom and skills of previous Avatars. They might guide him on how to defeat Azula specifically. He could learn a new bending technique from one of his past lives that gives him an edge over Azula's firebending, like a unique way of using water to extinguish her most powerful fire blasts.
