Another possibility in fanfiction is that Naruto forms a special bond with a powerful creature. Similar to how he had a bond with the Nine - Tails, but this time it could be a mythical beast from a different dimension. This bond might allow him to access a whole new set of powers, such as the ability to transform into a hybrid form with enhanced abilities like flight and super strength.
One common factor is the discovery of hidden bloodlines. Fanfic authors often write about Naruto finding out he has some long - lost bloodline ability. This could give him access to new and powerful ninjutsu. For example, a bloodline that allows him to control elements in a more advanced way than before.
Another possibility is that he gets help from a powerful ally. This ally could be a sage or a spirit who bestows upon Naruto the power of invisibility. They might see Naruto's potential and the importance of his mission and decide to give him this special ability. It could also be a side - effect of a powerful transformation he undergoes, like a new sage mode or some other super - powered form that has the added benefit of making him invisible.
In many fanfictions, Naruto might become a Jounin through extraordinary feats. For example, he could single - handedly defeat a powerful new enemy threatening the village. His Rasengan technique might evolve into an even more powerful form that convinces the village elders of his capabilities. Also, his leadership skills could shine during a difficult mission where he successfully guides a team of inexperienced ninjas to victory.
It could be that after some great battle where the Hidden Rain is left in a state of chaos, Naruto steps in to help rebuild. His selfless actions during this time earn him the trust and respect of the Rain villagers, leading to him being named the Amekage. He might have used his Rasengan and Sage Mode skills to protect the village during the battle, which makes him a natural choice for leadership.
It might change his fighting style significantly. Instead of relying solely on his ninjutsu and taijutsu, he would now incorporate swordsmanship. This would require him to train in a different way and develop new skills. Also, the sword could give him an edge in battles, allowing him to defeat opponents he previously couldn't. For instance, against opponents with strong defenses that his normal attacks couldn't penetrate, the sword could be the key.
Well, often in fanfiction, Naruto's growth as a better ninja comes from his increased understanding of the nature of chakra. He might discover new ways to manipulate it, like fusing different types of chakra in a more efficient and powerful way. This could lead to him developing new and stronger ninjutsu, making him a more formidable ninja.
In some fanfictions, Naruto and Kurama start to understand each other during their battles. As Naruto constantly shows his determination and never - gives - up attitude, Kurama begins to respect him. For example, when Naruto is facing a powerful enemy and still tries his best even on the verge of exhaustion, Kurama sees his tenacity and starts to have a change of heart. This is a common way for them to start building a friendship in fanfiction.
In some fanfictions, Naruto might start by trying to understand the Kyuubi's pain. He could use his own experiences of being an outcast in the village to empathize. As he shows this understanding, the Kyuubi begins to see him as different from the other humans who just fear it. They might start having conversations in Naruto's mindscape, gradually building a bond of mutual respect.
In some fanfictions, Naruto might become a genjutsu master by training intensively with a reclusive genjutsu expert. This expert could teach him unique and ancient genjutsu techniques that are not commonly known in the ninja world.
In some fanfictions, Naruto becomes friends with Kurama through deep conversations. Naruto, being persistent, tries to understand Kurama's pain and anger. He shares his own experiences of being alone and ostracized. This mutual sharing of feelings gradually breaks down the barriers between them, leading to friendship.
