He might face new and powerful enemies. In fanfiction, there could be hidden threats in the outside world that are different from those in the village. These enemies could have unique abilities that Naruto has never encountered before, testing his combat skills and strategic thinking.
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.
They could face challenges from the ninja world's authorities who might see them as deserters. Other villages might try to capture them to gain an advantage over Konoha.
One of the main challenges Naruto might face is dealing with political intrigue within the village. There could be clans vying for more power and influence, and Naruto would have to balance their demands while keeping the overall peace. Another challenge could be external threats, like neighboring villages that might see Naruto's leadership as a chance to attack. Also, he would need to ensure the economic stability of the village, which includes things like proper resource management and trade relations.
He could meet other powerful ninjas from different villages. Maybe some reclusive ninjas who are experts in certain jutsu that can help Naruto enhance his skills. For instance, he might come across a ninja who is a master of water jutsu in a far - flung land near a large body of water.
One challenge could be overexertion. He might push his body too far and risk injury. In fanfiction, Naruto's intense training might also attract unwanted attention from enemies who see his growth as a threat. Another challenge could be self - doubt. Despite his determination, there might be moments when he questions if his efforts are enough to reach his goals.
One challenge could be Naruto's stubbornness. Naruto has his own ideas and ways of doing things, and getting him to listen and follow Kakashi's guidance might be tough. Another is dealing with Naruto's past traumas. Kakashi would need to help Naruto overcome his feelings of loneliness and being an outcast. Also, Kakashi has his own responsibilities and missions, so finding time to be a proper adoptive father could be a struggle.
Communication could be a big issue. Naruto has his own way of expressing himself in his world, with his ninja jargon and unique gestures. Kim, with her own lingo from her action - packed life, might find it hard to fully understand Naruto at times. Also, they both have their own sets of friends and allies. Naruto's friends like Sasuke and Sakura might not immediately get along with Kim's friends like Ron and Rufus. This could cause some tension in their married life.
In a married fanfiction, Naruto and Kurotsuchi may face challenges in terms of their busy schedules. Naruto, as Hokage, has a lot of responsibilities in Konoha, and Kurotsuchi also has important duties in Iwagakure. They might struggle to find time for each other. Also, there could be political pressures. Their marriage is not just a personal union but also a connection between two powerful villages. Political factions in both villages might try to use their marriage for their own gains, putting stress on their relationship.
One challenge could be time management. Naruto is always so busy with his ninja duties, protecting the village and going on missions. Finding the time to sit down and write would be tough. Also, he might struggle with grammar and spelling since his ninja training didn't really focus on that.
One challenge could be gaining the trust of the Root members. Since Root has a history of being a secretive and somewhat feared organization, the members might be skeptical of Naruto's leadership. They're used to a more authoritarian style, and Naruto's more open and friendly approach could be met with resistance.
