At first, it would be a huge adjustment for Naruto. He's used to the Hidden Leaf Village, a very different environment from Stark Tower. But Naruto is adaptable. He would slowly get used to the high - tech lifestyle. He'd find similarities between the teamwork in the Avengers and his ninja team back home. Also, Tony would probably be patient with him and help him understand things like modern education, which Naruto didn't have much of in the ninja world.
Naruto would adapt to living with Tony Stark in several ways. His ability to make friends easily would help him bond with the Avengers and other people in Stark Tower. He would also use his ninja training discipline to learn about new things. For example, he'd apply his focus from learning ninja techniques to understanding how Tony's inventions function. Naruto's strong will would also play a role. He wouldn't be intimidated by the new and unfamiliar. Instead, he'd see it as an opportunity to grow and become stronger, just like he always has in his ninja life.
In a fanfiction, Tony Stark's adaptation to Winterfell life would be a journey. At first, he'd be completely out of place. His shiny Iron Man suit would stand out like a sore thumb among the furs and leathers of Winterfell. But he's smart. He'd start by making small changes. He'd use his engineering skills to improve the living conditions in a way that's acceptable to the people there. For instance, he could design a better heating system for the castle that doesn't rely on modern technology but still uses some of his scientific principles. He'd also have to adapt his language. He's used to using technical jargon, but in Winterfell, he'd need to communicate in a more straightforward and simple way. He'd gradually become part of the community, participating in hunts, helping with the harvest (if there is one), and eventually becoming a respected figure in Winterfell, all while still maintaining his unique identity as Tony Stark.
Tony Stark is a very intelligent and adaptable character. If he wakes up in the past in fanfiction, he would initially be confused but then quickly start to plan. He might use his charm and intelligence to get close to important people in that time period. He would also start making changes to Stark Industries' operations. He could introduce new safety protocols and start research on projects that were only possible in the future in his original timeline. He would be careful not to arouse too much suspicion while still making significant changes to improve things for the better.
Naruto would probably be very excited to meet Tony Stark. He'd be asking a million questions about all the cool gadgets. Stark, on the other hand, might be a bit put off at first by Naruto's exuberance but would soon warm up to him when he realizes Naruto's skills. They'd likely end up sharing stories about their respective worlds.
Leo would likely adapt by using his intelligence. He's already a clever character. He might start by learning about the technology. He could compare it to the mechanics he's used to in his own world. For instance, if he sees how a Stark suit works, he might find similarities to the machines he's built before.
Naruto adapts by becoming one with the forest. He observes the animals and learns from their behavior. For example, he sees how squirrels store nuts for the winter and starts doing something similar with his food supplies. He also gets used to the sounds of the forest at night, which at first might have been scary but then becomes a normal part of his life. He may even start using the natural elements of the forest like vines to help him in his ninja training.
Tony will have to adapt his mindset as well. The long - running war will take a toll on him. He might become more ruthless in his approach to end the war quickly. But at the same time, he'll still hold on to his values. He'll find a balance between doing whatever it takes to win and not losing his humanity. This internal struggle could be a big part of how he adapts to the situation in the fanfic.
She would likely be very frustrated at first. The Dursleys' strict and non - magical lifestyle would be a big contrast to what she's used to in the wizarding world. But being Hermione, she'd quickly start looking for ways to make the best of it. Maybe she'd create a little 'study corner' in her room using some makeshift magical tools.
Tony might interact with the inmates in a rather cocky way at first. He's used to being in control and having the upper hand. But as he gets to know them, he could start to see them as more than just criminals.
He would surely meet Black Panther. As the king of Wakanda, Black Panther would be the first and most important person Tony Stark would encounter.
He might become more cautious. In the DC Universe, there are a lot of powerful and unpredictable entities. So, he could tone down his cocky side a bit.
