Naruto could potentially gain access to Kumo's secret techniques. Kumo has some powerful and unique ninjutsu that are not available in Konoha. For example, he might learn a special form of body - enhancement technique that further boosts his already impressive physical abilities. He could also start to train with different types of weapons that are more common in Kumo, which would add a new dimension to his fighting style.
He might gain unique lightning - based jutsu training in Kumo. Since Kumo is known for its strong lightning - style ninjas. Also, he could develop a new form of Rasengan that incorporates lightning chakra, which he may not have had the opportunity to do in Konoha.
Well, in this fanfiction scenario, Naruto might be betrayed by Konoha due to the long - standing distrust of the Nine - Tails within him. When he joins Kumo, he could be used as a weapon against Konoha at first. However, Naruto being Naruto, he would try to change the Kumo way from within. He'd show them that power isn't everything and that friendship and loyalty are important too. This could lead to a change in Kumo's attitude towards Konoha and even start a new era of cooperation between the two villages.
His relationships would become very complex. His friends in Konoha would be in shock. Naruto leaving Konoha for Kumo is like a slap in the face to them. They would wonder what drove him to such a decision. For example, Naruto had such a strong bond with Iruka - his first mentor. Iruka would be deeply saddened and would question if he had failed Naruto in some way. And Naruto's relationship with Kakashi would also take a hit. Kakashi would be worried about what this means for the future and how it could potentially lead to conflict between Konoha and Kumo.
Well, in Kumo, Naruto might face challenges related to power struggles. There could be certain groups or individuals in Kumo who see Naruto as a threat to their own influence. He's a powerful ninja from Konoha, and some in Kumo might not want him to gain too much power or popularity there. Another biggie is making new friends. It's not easy to break into an established social circle in a new village, and Naruto might find it hard to find people he can really trust and rely on.
The journey itself could be full of danger. There could be bandits or rogue ninja along the way who target Naruto because of his fame. Also, the terrain between Konoha and Kumo might be difficult to traverse, with mountains, rivers, and forests full of wild animals.
One possible reason could be a mission. Maybe the Hidden Cloud Village (Kumo) requests Naruto's help specifically for a very important and dangerous mission that can only be accomplished by him. So, he has to leave Konoha for Kumo.
Well, one possibility is that Naruto would face a lot of distrust in Iwa at first. He's from Konoha, after all, which has had a history of conflict with Iwa. But Naruto being Naruto, he might gradually win over some of the Iwa ninjas with his determination and unique skills. He could learn new jutsus specific to Iwa's style of fighting, which would make him an even more formidable ninja.
Well, his relationships in Konoha would be in shambles. His friends like Sakura and Shikamaru would be shocked and sad. Sakura might feel guilty for not standing up for him more. And Naruto's relationship with Kakashi would be severely strained as Kakashi couldn't prevent his banishment. His enemies in Konoha might feel a sense of victory, but his true friends would always hold a place for him in their hearts.
His character could become more adaptable. In Kumo, he'd be exposed to different values and ways of life. This would make him more open - minded. For instance, he might start to view the concept of power in a new light, as Kumo has a different emphasis on strength compared to Konoha.
If Naruto joins Kumo in fanfiction, it might start with Naruto being sent on a mission to Kumo as an ambassador of sorts. Once there, he becomes intrigued by their combat techniques and decides to stay for a while to train. He could get involved in Kumo's internal power struggles. For example, there might be a faction in Kumo that doesn't trust him and tries to drive him out, while another faction sees his potential and wants to keep him. His presence could also change the dynamics between Kumo and other ninja villages as they see Naruto's new allegiance.
Naruto could potentially gain the power of mind - reading magic. This would be a huge advantage in both the wizarding war and in his interactions within Konoha. He could also gain the ability to transform into magical creatures, which would give him new forms of attack and defense. Another possibility is that he gains the power to nullify magic, which would make him a key player in the fight against wizards who use dark magic.
