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.
Naruto could face the challenge of being homesick in Kumo. He has grown up in Konoha and has strong emotional bonds with the people and places there. In Kumo, he is in a completely new environment. Additionally, he may have to deal with different political situations. Kumo might have different relationships with other villages and Naruto may get caught in the middle of some complex diplomatic issues. For example, if there is some sort of tension between Kumo and another village that Naruto has ties to, he will have to navigate that carefully.
He might meet a young and idealistic ninja in Kumo. This ninja could show Naruto a different way of looking at the ninja world. Maybe this Kumo ninja has a more peaceful approach to resolving conflicts, which makes Naruto re - evaluate his own views on fighting and rivalry between villages.
Adapting to a new ninja system could be a big challenge. Kumo may have different training methods, rules, and traditions compared to his home village. Naruto would need to learn and adjust quickly if he wants to survive there.
One challenge could be the powerful ninja from Kumo. They are known for their strength and combat skills. Naruto would have to face them in order to rescue Kushina.
In some fanfictions, Naruto might face new challenges in Kumo. He could encounter different ninja with unique jutsus. Maybe he has to prove himself all over again in this new village environment.
One possible plot could be that Naruto goes to Kumo but is not well - received there. Maybe the people of Kumo are still suspicious of him because of his status as a Jinchuuriki. They could isolate him, and Naruto has to struggle to prove himself worthy of their trust. He might also face discrimination from some of the Kumo ninja.
First of all, Naruto arriving in Kumo could disrupt the power balance there. Some might see him as a threat, while others as an opportunity. He could get involved in Kumo's internal politics. Since he's always been about making friends, he might try to bridge the gap between Kumo and Konoha, even though he was banished from Konoha. He could also discover secrets about Kumo that are related to his own past or abilities. For example, there could be some ancient Kumo jutsu that only he can master due to his Uzumaki heritage.
In the 'naruto goes to kumo fanfic', Naruto could be on a mission in Kumo. He might make new friends or enemies. He could also learn new jutsu from the ninjas in Kumo. It could be a great opportunity for him to grow as a ninja and expand his understanding of the ninja world.
Naruto might meet some young and talented Kumo ninjas. They could be eager to test their skills against Naruto or learn from him. Maybe there are some unique characters like a Kumo ninja with a special bloodline limit that Naruto has never seen before.
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.
Another possibility is that there is a rogue ninja in Kumo who uses Naruto's neglected state to his advantage. He might try to manipulate Naruto into doing things that would be bad for both Naruto and Kumo, all while remaining in the shadows and making it seem like Naruto is acting on his own accord.
