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.
Kakashi would approach Wonderland with his usual laid - back yet observant attitude. He might be interested in the different kinds of magic and abilities in Wonderland and try to learn from them. As for Sakura, she would probably be a bit more hesitant but also curious. She could use her medical ninjutsu to help any injured Wonderland creatures, which would earn her some allies in this new world.
Naruto, on the other hand, would approach it with his usual optimism. He would try to make friends with as many people as possible. He would see the oppressed in Deadman Wonderland as people he needs to protect. He would use his Rasengan and other jutsus in creative ways during the battles there. He might also try to bring some of the Naruto - world values like friendship and loyalty to the rather cut - throat world of Deadman Wonderland.
Naruto, on the other hand, would be more about the fun and social aspects at first. He'd love using social media to share his ninja adventures and connect with people from different villages. But he'd also see the practical uses, like using GPS to find his way during missions. He might have some trouble with the more complex tech at first, but his determination would help him learn.
Naruto would probably be excited about the new weapons and technology. He'd quickly try to learn how to use guns and modern combat vehicles, while also showing off his ninja skills. Sasuke, on the other hand, would be more reserved. He'd analyze the new military strategies carefully and find ways to incorporate his Sharingan and swordsmanship into modern combat.
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.
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.
Sakura would adapt by using her medical knowledge. She might study the necromorphs to see if there's a way to reverse their mutations. She'd also be a great support to the group, using her strength (which she's developed in Naruto) to protect the more vulnerable survivors from Dead Space. She could also use her chakra control to create barriers against the necromorphs.
Naruto characters would likely face a huge challenge in adapting to the Terra Formars world. The environment is harsh and the enemies are very different from what they are used to. However, their ninja skills would still be useful. For instance, their stealth abilities could help them avoid detection by the Terra Formars.
The ninja from Naruto would initially be shocked by the sheer size and power of the dinosaurs. But they would soon adapt. For example, they could use their tree - climbing skills to escape from ground - based threats. They'd also have to learn about the different types of dinosaurs and their behaviors. Naruto might try to communicate with them using his animal - taming skills, though it might not work as well on these prehistoric beasts. And they would all have to work together to find a way back home if they got trapped in the Jurassic World.
Naruto would probably be very curious at first. He'd try to communicate with them, using his friendly and open - minded nature. Sasuke might be more cautious and view them as potential threats. The ninja in general would adapt their fighting styles. They'd incorporate the Predators' stealth and long - range attacks into their own combat. For example, they might learn to use kunai in a more silent and deadly way like the Predators' throwing weapons. With the Aliens, they'd have to deal with their acidic blood, so they'd need to be extra careful with their attacks.
In a fanfiction, Naruto characters would have to learn the rules of the Dark Souls 3 world. They would need to understand how to manage their 'souls' (equivalent to chakra in some ways). For example, characters like Shikamaru, with his high intelligence, would be able to strategize about when to fight and when to retreat. He could use his shadow - binding jutsu in creative ways to trap enemies. And characters like Hinata might be more cautious, using her Byakugan to detect hidden enemies, much like in Dark Souls 3 where you need to be aware of ambushes.
