One possibility is that Naruto goes to Whirlpool to seek some sort of power or knowledge. He could stumble upon ancient scrolls or training methods that are specific to the Whirlpool region. He may also find himself in a situation where he has to protect the people of Whirlpool from an external threat, like a group of rogue ninjas or a powerful demon.
In such a fanfiction, perhaps there could be an alliance between the Whirlpool and Sand villages. Their unique jutsus and cultures might blend. For example, the water - based techniques of the Whirlpool could be combined with the Sand's desert - based strategies in battles against a common enemy.
Naruto might discover new Uzumaki techniques. Since the Uzumaki clan was known for their strong sealing jutsu, he could learn some advanced sealing techniques during his visit to Whirlpool. Maybe he'd find a special scroll left by his ancestors that contains a powerful jutsu.
In some fanfictions, they might discover hidden jutsu. For example, there could be an ancient sealing technique that was lost in the Whirlpool country. Naruto, with his curious nature, would be eager to explore and learn about it, while Hinata would be by his side, supporting him and using her Byakugan to sense any potential danger.
He might face unique challenges. Hozukijou could have its own set of rules and obstacles that Naruto has to figure out, like perhaps different types of jutsu or magic that are specific to that place.
Well, Naruto might face a lot of challenges in Iwa. He could encounter new types of jutsu that are unique to Iwa ninjas. Maybe he'll make some new friends or foes there.
In this fanfiction, Naruto might face new challenges in Suna. He could encounter different shinobi with unique fighting styles. Maybe he'll form new alliances or have some interesting cultural exchanges.
Well, he might encounter new and powerful ninjas. In Kiri, there are strong water - style ninjas. Naruto could learn new techniques or gain new allies. Maybe he'd get into some battles and show off his Rasengan to the Kirigakure folks.
Naruto arriving in the DBZ universe in a fanfiction would be a wild ride. He'd probably have to adjust to the different rules of combat. The Z - Fighters might be curious about his shadow clones and how he can create so many of them. Naruto could also be a bit shocked by the destruction caused by the battles in DBZ. He might try to find a more peaceful solution to conflicts, like he does in his own world. And perhaps his positive attitude would rub off on some of the more hot - headed DBZ characters.
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.
In some fanfictions, Naruto might go to Orochimaru seeking power. He could be tempted by Orochimaru's knowledge of jutsu. Maybe he thinks that by learning from Orochimaru, he can become stronger faster and be better able to protect his friends and the village.
