Well, he might be completely out of his depth at first. Naruto's ninja skills are cool, but in the DBZ universe with all those super - powered Saiyans and other strong beings. He'd probably try to make friends and learn about the new world. Maybe he'd try to use his Rasengan against a Ki blast, which would be an interesting sight.
He might use his ninja skills to survive in Westeros. His ability to move stealthily and his combat skills could make him a formidable figure. He could also form alliances with some of the characters in Westeros, perhaps teaching them some of his ninja techniques in return for knowledge about the land.
In this kind of fanfiction scenario, Naruto could face challenges from future villains who have powers he's not familiar with. However, his own experience and strong will would still be valuable assets. He might also meet descendants of his friends and discover how his actions in the past have influenced the future in ways he never expected. For example, he could find that a village was founded in his honor, or that a new style of ninja training was developed based on his teachings.
Well, Naruto's ninja skills would be quite a shock to the AoT world. He could probably use his Shadow Clone Jutsu to confuse the Titans. Maybe he'd team up with the Survey Corps and teach them some new combat moves. His chakra control might also give him an edge in using the ODM gear more effectively.
Well, Naruto would probably be really confused at first. He'd see all the bending and different cultures. He might try to use his ninja skills, but soon realize they work a bit differently here. He could end up making friends with Aang or Korra. Maybe he'd learn some bending too, like he learned new jutsus in his own world. It would be a wild adventure for him, full of new challenges and things to discover.
In the time of Hashirama, Naruto would be quite an anomaly. He could introduce new concepts like the idea of different villages working together more amicably. Since Naruto has a way of befriending people, he might even befriend the young Uchiha clan members and prevent some of the future animosity between the Uchiha and Senju. And his chakra levels and control would surely impress Hashirama.
If Naruto were in the DBZ world, he could potentially learn to use ki. Since he's good at adapting and learning new techniques. He might combine his shadow clone jutsu with ki energy. Imagine hundreds of Naruto clones all shooting out ki - enhanced attacks. However, he'd also face some serious challenges. The villains in the DBZ world are extremely powerful and often planet - destroying threats. Naruto's usual foes are not on that level, so he'd have to level up fast.
When Naruto is in a DBZ fanfiction, his abilities are quite different from the DBZ characters. His chakra - based jutsus are not the same as Ki - based attacks. For example, Goku can transform into a Super Saiyan and gain immense power. Naruto doesn't have such a transformation in the same sense. However, Naruto's ninjutsu are versatile. His Rasengan can be a concentrated and powerful attack, but it's still not on the level of a Kamehameha in terms of raw power. But he could use his agility and clone jutsu to outmaneuver some DBZ characters.
If Naruto ends up in a female ninja world, he could bring some unique male - influenced ninja techniques. This might disrupt the existing order in that world a bit. He could also form some interesting relationships. For example, he might find himself in the middle of female - only ninja clans and have to navigate their politics. There could be some initial resistance from the female ninjas towards him, but eventually, they might learn from each other.
He would probably be very confused at first. The tall buildings, the busy streets and all the strange technology compared to his world in Konoha would be overwhelming.
One possibility is that Harry would use this opportunity to change certain events in the past that had a negative impact on the baby or its family. He could also form a special bond with the baby. Maybe he'd introduce the baby to some of his friends from his own time who are also in the past now. This could create a whole new set of relationships and storylines in the fanfiction.
