Naruto would adapt by using his ninja skills. His speed and agility from being a ninja would help him in exploring Earthland. He could also use his rasengan as a powerful attack against any potential enemies. He might start by finding a place to stay and learning about the local customs.
Well, Naruto has always been adaptable. In a Hive fanfic, he'd first try to communicate with the locals. His positive attitude would make it easier for him to get along. He could use his ninjutsu to his advantage, like using his transformation jutsu to blend in or gather information. He'd also be excited to learn new things in the Hive, which would further his adaptation process. His goal - setting nature would make him look for ways to improve the Hive or help those in need there.
He'd probably start by observing. Naruto is curious, so he'd watch how the Asgardians live, their customs, and how they interact. Then he'd start to adapt by using his ninja adaptability skills.
In a 'Naruto travel to the future fanfiction', Naruto would adapt through his strong sense of curiosity. He would be eager to explore every new thing he sees in the future. His resilience would also play a big role. If he encounters difficulties, like not understanding how a particular future - tech works, he won't give up. Instead, he'll keep trying until he figures it out. And his ninja training gives him discipline. He would use this discipline to study the new ways of life in the future, from the social norms to the technological advancements.
Naruto's adaptation to the Anbu in this fanfiction could be a complex process. At first, he'd probably struggle with the strict discipline and the need for secrecy. But his previous experiences in tough situations would come in handy. He'd gradually understand the importance of stealth and how to use his skills in a more covert way. He might also learn from the more experienced Anbu members, and his own determination would drive him to become a valuable part of the Anbu.
He would need to understand the social hierarchy in Kirigakure. In Konoha, he was used to a certain way of doing things, but in Kirigakure, there could be different rules regarding how ninjas interact with each other and with the village leaders. For example, he might have to show more deference to the Mizukage than he did to the Hokage. Also, he'd have to adapt to the food. Kirigakure is near the sea, so there would be a lot more seafood in his diet.
He could start by learning to control his new powers. Naruto is used to training hard, so he'd likely focus on mastering his kagune and other ghoul - related abilities. This would help him not accidentally harm anyone.
Sasuke would likely be very cautious at first. He'd be observing everything closely, trying to figure out the rules of this strange place. His Sharingan might give him an advantage in seeing through some of the illusions in Wonderland. Naruto, on the other hand, would probably be more excited and jump right into things, ready to make friends with the odd - looking creatures.
To adapt to being the Mandarin, Naruto would first need to understand the nature of the ten rings. He might start by experimenting with each ring's individual power. He'd then figure out how to combine these powers with his existing ninja abilities like rasengan. His relationships with other characters would also change. Some might be afraid of his new power, while others would see it as an opportunity to fight against greater threats. Naruto would have to convince them that he can be trusted with this power and that he'll use it for the greater good.
